Specific embodiment

The UE for forming the part of Internet of Things (IoT) will usually be connected only to wireless network up to short interval (for example, to provide one A little fragmentary services, such as the state or situation of report associated entity, object or personnel).For example, part as IoT UE may include the discontinuous feature for receiving (eDRX) or battery saving mode (PSM) of such as extension.In eDRX or PSM, UE can It is maintained at idle state, and long period can neither be reached from service radio network up to service radio network can not be connected to (for example, a few hours or longer).During UE is maintained at the period of idle state, client terminal device is (for example, positioning service (LCS) client) possibly UE can not be reached, thus limitation or prevention positioning service.This can prevent or hinder such as geography fence, Asset tracking and children or pet positioning real-time positioning service because possibly can not access UE or measurement the signal from UE with Enable the positioning that UE is obtained when UE is in idle state.A kind of this possible solution will be allowed needing in real time Position access period during in IoT UE activation cycle and triggering positioning reporting.However, (for example, passing through 3GPP) only needle To usually reachable at any time UE rather than usually inaccessible UE defines the existing process for period and triggering positioning. For example, a few hours or a couple of days in inaccessible period and triggering positioning possibly can not be originated in UE using present procedure.

The new procedures described herein for supporting different types of period and triggering positioning.New procedures can be used for usually any Time reachable UE and for a long time both inaccessible IoT UE, for example, due to the discontinuous reception (eDRX) of such as extension Or the feature of battery saving mode (PSM).Described program may include fisrt feature comprising be directed to target UE in LCS client starting Period and trigger positioning reporting request after, by network by two intermediate responses return to LCS client.First response It can indicate that LCS client request is received by network and network is ready to originate described program in target UE.With traditional journey Sequence is different, it is possible to provide the second response, instruction activation cycle and triggering Location Request in UE, that is, target UE will start to return Period and triggering positioning reporting.Second response can return quickly after the first response, for example, for normal UE, or can be the A few hours or a couple of days return after one response, for example, for IoT UE.

New procedures can additionally comprise second feature, and the second feature includes the maximum for period and triggering Location Request Report interval, wherein report triggering event rather than periodic event, even if to force UE that normal report event is not yet occurring When also issue positioning reporting.Receiving positioning reporting can be still effective in UE to network and LCS client confirmation positioning reporting.Separately On the one hand, if being not received by positioning reporting after maximum report interval, LCS client or network may be assumed that positioning It is reported in UE and terminates, and then can terminate and/or clearly cancel the request.This can avoid traditional polling routine, institute It states traditional directory and crosses range request LCS client or network entity and periodically inquire UE and carrying out location sessions to determine and be It is no still effective.In some aspects of second feature, minimum report interval can also be included to avoid excessively most from UE Mesh positioning reporting.It can be frequent for example, minimum report interval is equal to some short cycle (for example, 10 to 15 minutes) Occur to be avoided when trigger event from a large amount of reports of the UE in short time (for example, one hour).

The new process can further include third feature, and the third feature includes the maximum event sampling interval, it is described most The major issue sampling interval can define the maximum time interval between two continuous samplings movement of UE, and wherein UE determines determining for request Whether position trigger event has occurred and that, such as because UE has moved more than threshold distance or entered or left specified target area Domain.If above situation is that possible can be used to be less than the maximum event sampling interval without more excessive power drains, UE Sampling interval.Increase the maximum event sampling interval can be reduced by possibly reducing the frequency of UE sampling action UE power and Battery consumption, but the delay for the trigger event that report has occurred can also be increased.Therefore, the maximum event sampling interval can be by LCS visitor Family end adjustment, to realize the optimal tradeoff between power and battery consumption and report the required positioning service of best match target UE And the delay of the trigger event of ability.The maximum event sampling interval can be contrasted with the minimum event sampling interval, and can provide Flexibilities more more than the minimum event sampling interval, in the minimum event sampling interval, UE needs to verify trigger event at some Whether minimum interval has occurred.For example, when UE can support above situation in the case where no significant excessive power drain When, the minimum event sampling interval can prevent UE from using the shorter sampling interval.As example, as vehicle part or be attached to Vehicle or possess their own charging source (for example, by mobile power supply of light, heat or user) UE can in terms of power consumption by To less limitation.

Under the situation of OTDOA, UE 102 can measure signal (such as by transceiver and base station near in pairs (for example, ENB 122 and 124) transmitting location reference signals (PRS) or cell specific reference signal (CRS)) between reference signal when Between poor (RSTD).RSTD measured value may be provided at UE 102 from two different transceivers (for example, from eNB 122 and eNB 124 RSTD between received signal) reaching time-difference between received signal (for example, CRS or PRS).UE 102 can will be surveyed The RSTD of amount returns to location-server (for example, E-SMLC 133), can known locations based on the transceiver measured and Known signal timing positions to calculate the estimation of UE 102.Signal in some embodiments of OTDOA, for RSTD measurement (for example, PRS or CRS signal) can be exactly synchronous to the shared generation of such as GPS time or Coordinated Universal Time(UTC) (UTC) by transceiver When boundary, universal time is shared for example, accurately obtaining using GPS receiver in each transceiver.

The estimation of the positioning of UE 102 can be referred to as positioning, location estimation, location fix, orientation, position, location estimation Or location fix, and can be geographical measurement, therefore the positioning coordinate (for example, latitude and longitude) of UE 102 is provided, it can wrap Contain or can not include altitude component (for example, height above sea level, the height on ground level or the depth under ground level, flooring it is horizontal or Basement is horizontal).It alternatively, can be municipal administration positioning by the localization and expression of UE 102 (for example, as postal address or for example specific The title of some point or zonule in the building of room or floor).The position of UE 102 can also be expressed as expected UE 102 Region therein or volume are positioned at (geographically or with municipal administration with some probability or confidence level (for example, 67% or 95% etc.) Form defines) etc..The position of UE 102 may further be relative position comprising for example relative to some known position The distance and direction or opposite X, Y (and Z) coordinate that some origin defines, the known location can be geographically or in a manner of municipal Or the point, area or the volume that indicate on Reference Map, plan view or architectural plan defines.The description for being included herein In, the use of term registration may include any variant in these variants, unless otherwise directed.

Using Mobile Termination Location Request (MT-LR) program pin to the GSM carried out in 3GPP TS 23.271 by UE 102 The triggering for being defined on UE 102 under the request of external client (such as external client 160) with UMTS access positions (for example, base In zone issue) and period positioning.Different MT-LR processes is defined in 3GPP TS 23.271 to support the period of UE 102 Positioning (being positioned using MT-LR program for the period) and the triggering of UE 102 are positioned, and wherein UE 102 enters, leaves or be maintained at The geographical inner region defined (using MT-LR routine change zone issue).However, in 3GPP TS 23.271 for by UE 102 carries out E-UTRAN access (for example, using LTE or NB-IoT) and defines such MT-LR program (for example, for period position The change of the MT-LR program or zone issue set).Under the situation for the CIoT feature that UE 102 is used, in 3GPP TS The ability of the position change of report UE 102, but the positioning in solution and 3GPP TS 23.271 are supported in definition in 23.682 It supports inconsistent (for example, because the ability in 3GPP TS 23.682 is used with the solution in 3GPP TS 23.271 not Same framework and different agreement), the positioning of the granularity of cell ID or tracing area (TA) is only provided, and only becoming in UE 102 can Used time report positioning (for example, under the situation for the long eDRX paging cycle of UE 102, it may be between almost three hours Every).

The MT-LR ability in more flexible period and/or triggering can be used for realizing and be normally made available by UE 102 (for example, Be connected to VPLMN EPC 130) except time with LTE access, classification M1 access or NB-IoT access and/or have than The positioning of the UE 102 of the better granularity of cell ID or TA.For example, user may wonder valuable assets, children or pet The time of specific region is immediately entered or leaves after an event occurs, rather than after saying two hours, and in addition may prefer to work as This event more accurate current location when occurring.

Single program (for example, MT-LR program) can be used for supporting different types of period and triggering positioning.Herein this The example of single process is called that " period and triggering positioning ", " period and triggering MT-LR ", " period and triggering MT-LR are fixed Position ", " period and triggering positioning determine ", " period positioning and triggering positioning ", " period or triggering positioning ", " period position determines And triggering positioning determines ", or " period position is determining or triggering positioning determines ".In addition, can be at this to the request of this single program It is referred to as " period and triggering Location Request ", " MT-LR of period and triggering request ", " MT-LR of period and triggering positioning in text Request ", " period positioning and triggering request for location services ", " period or triggering Location Request ", " period Location Request and triggering are fixed Position request ", or " period Location Request or triggering Location Request ".Using supporting period and different types of triggering positioning reporting Single program may be better than individual program, and each program only support a type of report (for example, only periodic report or only reporting Accuse zone issue), this is because reducing the implementation of UE 102 and/or for such as MME's 131 and GMLC 132,142 and 152 Network element.Program can be used for usually reachable at any time both inaccessible IoT UE 102 of UE 10 and long-time.Institute Program is stated containing the several features for supporting positioning service, for example, being used for IoT UE.In a feature of the process, LCS client (for example, external client 160) requests network (for example, R-GMLC 152) starting for target UE (for example, UE 102) after period and triggering positioning reporting, two intermediate responses can be returned to by network (for example, passing through MME 131) LCS client.The first response that can usually return in seconds can indicate that LCS client request is received by network or network (for example, passing through R-GMLC 152, H-GMLC-142, V-GMLC-132 and MME 131) and network (for example, MME 131) prepares Fortunately initial orders in target UE.Second response can for normal UE first response after soon (for example, several seconds it Return afterwards), or can after for the response of the first of IoT UE a few hours or a couple of days return, can indicate that period and triggering positioning ask It asks and is activated in UE.Different from the traditional program for not providing this second response, the second response can notify LCS client target UE It will start return period and triggering positioning reporting.

In UE (for example, UE 102) activation cycle and triggering positioning reporting after, UE can these occur and examined by UE The type of requested period and/or trigger event is reported when measuring, and may include these report location estimation (or network may Include location estimation).However, when trigger event does not occur (for example, UE is maintained in geography fence region and does not need to report This situation), network (for example, R-GMLC 152 and H-GMLC 142) and LCS client (for example, external client 160) may Any positioning reporting is not received, so that network or LCS client can not can know that Location Request effective or quilt still in UE It terminates (for example, since UE is powered down).Traditionally, additional queries program can be used, allow LCS client or network entity (for example, GMLC) inquires ongoing effective position session living to UE.However, determining the positioning with UE using additional queries The current state of session may will increase the influence to wireless network and UE, and when the UE in idle state is unreachable for a long time When may cause delay response.Another feature of program described herein can provide the more effective solution with less delayed Certainly scheme, wherein the period and triggering Location Request for trigger event (for example, zone issue report) provide maximum report interval Even if can also generate positioning reporting to force UE publication there is no normally reporting event.Positioning reporting can to network (for example, R-GMLC 152 and H-GMLC 142) and LCS client (for example, LCS client 160) confirmation positioning reporting in UE still Effectively.If being not received by positioning reporting after maximum report interval, LCS client or network are (for example, R-GMLC 152 and H-GMLC 142) it may be assumed that and terminate positioning reporting in UE.

EPC service period and triggering positioning can support with periodic intervals or whenever UE detect some trigger events and Cancel positioning reporting (for example, by UE or LCS client) Shi Faqi positioning reporting.For example, being supported for positioning reporting Trigger event may include zone issue (for example, UE enter, leave or be retained in predefined region in the case where) and fortune Dynamic event.It in one embodiment, can only include a type in any request in period, zone issue and motion event The report of type.It in another embodiment, can be for identical period and triggering finder (for example, from period, zone issue And in motion event report) support the report of more than one type.Under the situation of zone issue, target area can for example pass through For PLMN, the geographic area of country or geopolitics title, PLMN mark, cell set and/or TA definition.In motion event Under situation, movement can be more than for example linear range threshold corresponding to the previous position by UE progress from the UE UE for reporting motion event The movement of value.Described program can support the UE mobility between different service MME and different service PLMN without interrupt event report It accuses.

Fig. 2 shows signaling process 200, illustrates the MT-LR for period and triggering for LCS client request and has The target UE of LTE and/or NB-IoT wireless access initiates and executes the process of event and positioning reporting.Example in Fig. 2 and slightly UE 102 of the exemplary application shown in Fig. 3 and 4 afterwards in system architecture 100, wherein using identical number in Fig. 2 to 4 Show the element from system architecture 100.As illustrated in signaling process 200, at the stage 1, LCS client 160 is to R- GMLC 152 sends LCS service request, provides the type of requested positioning (or locating events) report (for example, entering Left in region, from region, in region, the report of regular reporting or motion event) and associated parameter.In this example, false It is located at the stage 1 and only requests a type of positioning reporting (for example, for example in periodic event but non-area event or motion event Stage 1 at request report).However, it is possible in the presence of the other example (examples for the positioning reporting for wherein requesting more than one type Such as, it is requested at the stage 1 of both reporting cycle event and motion event).For any kind of report, LCS service request It may include the mark containing UE 102, such as movement station international subscriber directory number code (MSISDN), international mobile subscriber number (IMSI) or some other marks known to LCS client 160 and R-GMLC152.For regular reporting, for example, LCS service is asked The time interval between the total number that can further include consecutive tracking report, report is sought, and may include may include required position The location quality of service (QoS) of accuracy.For example, (for example, entering in region, being left from region for zone issue report Or in region), LCS service request can further include the details of target area (for example, geographical or urban target region determine Justice), the event to be reported be UE in target area, into target area or leave target area, event report it is lasting when Between, continuous events report between minimum and/or maximum time interval, maximum event sampling interval, location estimation whether can quilt Included in event report (and associated location QoS), and a positioning reporting or more than one positioning whether is only needed to report It accuses.If target area is expressed by local coordinate, city position or geopolitics title, R-GMLC 152 can be by target Region is converted to the geographic area indicated by the geographic shape of for example round, ellipse or polygon (for example, such as in 3GPP TS Defined in 23.032).Motion event is reported, for example, LCS service request can further include the triggering movement thing of UE 102 Part report movement threshold value linear range, event report duration, continuous events report between minimum and/or maximum Time interval, the maximum event sampling interval, location estimation whether may include in event report (and relevant position QoS), and Whether a positioning reporting or more than one positioning reporting are only needed.In some embodiments, LCS client 160 may be The information of the LCS service request sent in the stage 1 is received (in Fig. 2 not from another entity (for example, user of LCS client 160) It shows).

At the stage 2, the disposition of LCS service request is executed between GMLC 152,142 and 132.LCS clothes at 2nd stage Business request disposition may include following one or more: (i) inquires and is attained at UE 102 from HLR/HSS 144 by R-GMLC 152 142 address H-GMLC, 132 address V-GMLC, the address for servicing MME 131 and/or additional mark (such as MSISDN or One or more of IMSI)；(ii) LCS service request is forwarded to by H-GMLC 142 by R-GMLC 152；(iii) by H- GMLC 142 carries out privacy and authority checking to LCS service request；(iv) it is inquired and is obtained from HLR/HSS 144 by H-GMLC 142 Must be used for 132 address V-GMLC of UE 102, the address for servicing MME 131 and/or additional mark (for example, MSISDN or One or more of IMSI).As the part of the LCS service request disposition at the stage 2, H-GMLC 142 can be asked in LCS service Ask the received information of middle record institute and parameter.H-GMLC 142 can also be for example based on from the reception of HLR/HSS 144 or in advance in H- The user's correlation and subscription related information for UE 102 configured in GMLC 142, delays request (LDR) with reference to volume for position It number is assigned to LCS service request and optional report PLMN list (in this example should be comprising the clothes corresponding to VPLMN EPC 130 Be engaged in PLMN).Then, LCS service request is transmitted to V-GMLC 132 by H-GMLC 142, and includes LDR Ref. No., H-GMLC The user of 142 addresses, any optional report PLMN list and UE 102 and/or UE 102 notifies privacy or verifies optional Request.H-GMLC 142 is sent directly to by LCS client 160 in the LCS service request in the 1st stage rather than via R-GMLC Under the situation of 152 (for example, wherein R-GMLC 152 is identical as H-GMLC 142), it can omit only for the stage 2 for R- The movement that GMLC 152 is described.(for example, working as VPLMN EPC 130 under the situation identical with V-GMLC 132 of H-GMLC 142 For HPLMN 140 part when), 132 can be omitted from H-GMLC 142 to V-GMLC and send LCS service request.

At the stage 3, under the situation of request zone issue report, if target area defined by geographic shape (for example, As defined in 3GPP TS 23.032), then V-GMLC 132 target area can be converted to defined for RAN 120 it is small The corresponding lists of area's mark and/or tracing area (TA).If entire target area cannot be converted into for example by V-GMLC 132 The network identity of cell ID and tracing area, then V-GMLC 132 can be described in error reason (not showing in Fig. 2) refusal It requests and sends LCS service response to H-GMLC 142.Otherwise, V-GMLC 132 sends Location Request and relevant parameter to MME 131, for example, in user positioning request message is provided, the details comprising the event to be reported, LDR Ref. No., H- Any optional list of PLMN is reported in 142 address GMLC, and any optional request for notifying privacy or verifying.MME 131 can be the service MME for UE 102, and may be in response to as being previously directed to inquiry described in the stage 2, from HLR/HSS 144 offers are identified into the information of R-GMLC 152 or H-GMLC 142.

At the stage 4, MME 131 can verify that UE 102 about independently supplement services (example to the relevant calling of positioning service Such as, the notice of LCS) support ability, may previously by HLR/HSS 144 provide to MME 131 as UE102 subscribe to believe It (for example, when UE 102 is first attach to VPLMN EPC 130 or executes tracking area update, is not opened up in Fig. 2 the part of breath Show).If UE 102 does not support calling relevant to positioning service independently supplement service, or if MME 131 is not supported to fixed The Location Request (for temporarily or permanently reason) of phase and triggering positioning, then can be by MME 131 with suitable error reason User location errored response will be provided back to V-GMLC 132 (not showing in Fig. 2).Otherwise, MME 131 is to V-GMLC 132 Confirmation is returned, such as user's positioning confirmation (Ack) message is provided, is received by MME 131 with confirmation request.In one aspect In, confirmation may include in the current inaccessible situation of UE 102 until next time UE 102 becomes reachable interval expeced time Or the instruction (for example, this can be measured based on the remaining time in eDRX period or PSM period) of maximum time interval.In aspect, really Recognizing can also or alternatively be comprising the Last Known Location of UE 102, for example, if based on the UE's 102 being stored at MME 131 Information is available.Offer user positioning request message at the stage 3 and offer user's Relocation Commit message at the stage 4 can be such as It is defined in 3GPP TS 29.172 for EPC LCS agreement (ELP).

In some embodiments, the UE 102 directly indicated to period and the support for triggering Location Request may be not present Ability information.However, if UE 102 supports that independently supplement services (for example, for example the relevant calling of at least one positioning service The notice of LCS), then MME 131 can assume to support period and triggering positioning in some embodiments.In these embodiments, If the request that 102 nonrecognition of UE is sent in the stage 9 later, UE 102 can be in the stage 10 (for example, such as 3GPP TS Defined in 24.008) to the return of MME 131 errored response (for example, Facility Reject instruction), in this situation, MME 131 can It is terminated with the error reason appropriate at the stage 19 in the message (for example, user's positioning reporting) of transmission by initiation signaling flow The request that the stage 19 to 24 of journey 200 carries out.

At the stage 5 to 7, V-GMLC 132 returns to LCS service response via H-GMLC 142 and R-GMLC 152 Whether LCS client 160 receives period and triggering Location Request with notice.Then, LCS client 160 can return to notice Another entity (for example, user of LCS client 160) (not shown in Fig. 2).When H-GMLC 142 services LCS at the stage 6 When response returns to R-GMLC 152, it may include the LDR Ref. No. distributed at the stage 2 by H-GMLC 142, and R-GMLC Then 152 can distribute another Ref. No. by LDR Ref. No., or by R-GMLC 152 in LCS service response at the stage 7 It is transmitted to LCS client 160.The LCS service response returned at the stage 5 to 7 can be additionally included at the stage 4 comprising until in UE 102 become reachable and/or UE 102 Last Known Location (if any of these are included in the stage 4 next time Place) expection or maximum time interval instruction.Note that can be omitted the stage when R-GMLC 152 is identical as H-GMLC 142 6, and when H-GMLC142 is identical as V-GMLC 132, the stage 5 can be omitted.

Note that the LCS service response of message (for example, providing user's positioning confirmation) and 5 to 7 place of stage at the stage 4 is all It not can confirm that and activate positioning reporting or UE 102 that may allow for supporting request in UE 102.However, disappearing at the stage 4 The LCS service response at breath (for example, providing user's positioning confirmation) and 5 to 7 place of stage, which can confirm, supports the energy of request in network side Power and intention, and when the response from UE 102 since UE 102 is temporarily unreachable (for example, if locating due to PSM or eDRX In idle state) it may be useful to LCS client 160 when being delayed by.Offer user positioning confirmation and stage 5 to 7 at stage 4 The LCS service response at place can correspond to the one in two responses previously referred to for fisrt feature, the fisrt feature Including two intermediate responses are returned to LCS client by network.

At the stage 8, if UE 102 current unreachable (for example, when in PSM or in eDRX), MME 131 wait until UE 102 become again up to (for example, when UE 102 can be paged again in eDRX end cycle or Or if request the signaling connection to RAN 120 again in PSM).When UE 102 becomes reachable, UE 102 can be via RAN The signaling connection for arriving VPLMN EPC 130 is established in 120 requests, and in this condition, UE 102 and MME 131 can establish signaling company Connect and execute verifying and encryption.Alternatively, if UE 102 is becoming up to after in idle state (for example, in EPS connection In IDLE (ECM-IDLE) state of management), then the executable paging of MME 131, and then UE 102 and MME 131 is executable tests It demonstrate,proves and encrypts to establish the signaling connection of UE 102.If requesting privacy notifying/verifying (for example, in the stage 3 or according to MME The subscription information of 131 UE 102 obtained from HLR/HSS 144) and the support of UE 102 calling independence benefit relevant to positioning service The service of filling, then LCS position informing can be called message be sent to UE 102 by MME 131, as the part in stage 8, wherein position The activation of type instruction extension Location Request is set, extension locating events type indicates the type of positioning reporting event (that is, into area Domain is left from region, in region, period or movement) and about whether the instruction for needing to carry out privacy verification.If request Privacy verification, as the part in stage 8, refers to then UE 102, which can return to LCS position informing to MME 131, returns the result message Show whether permit or refuse the license to Location Request (for example, by user of UE 102).If UE 102 is when needing to respond Refusal license or not returning response, then MME 131 can terminate request as further described for the stage 11.At aspect In, if UE 102 become can to change before the arrival of MME 131 service MME 131 (for example, to new demand servicing MME, such as MME 131#), then message (for example, user's positioning reporting message) can be returned to the change of instruction MME 131 by MME 131 V-GMLC 132 and if available so may include new 131 address MME (for example, the MME when MME131# is new demand servicing MME The address of 131#) (not shown in Fig. 2).In in this regard, V-GMLC 132 then can be via H-GMLC 142 and R-GMLC Mistake is forwarded to LCS client 160 or repeatable stage 3 the case where providing (not showing in Fig. 2) by MME 131 by 152 It is lower that period and triggering Location Request are transmitted to new MME (for example, MME 131#).Hereinto aspect, when later by new MME (for example, MME 131#) again execute stage 4 when, V-GMLC 132 can not duplication stages 5 to 7 because the stage 5 ought initially be executed LCS client 160 has been apprised of network and receives the request when to 7.

Back to the signaling process 200 for normal (success) program, wherein program is not terminated and is not directed to another One MME, at the stage 9, MME 131 sends delivery in the stage 3 from V- for message (such as LCS period trigger calling message) The UE 102 of the received all information concerning events of GMLC 132, the type comprising positioning reporting event is (for example, enter region In, region is left, in region, regular reporting or motion event report), LDR Ref. No., 142 address H-GMLC, report PLMN optional list (provided that) and any request under the situation for needing location estimation QoS.

In the stage 10, if UE 102 is according to the received request support period at the stage 9 and triggers positioning, and mesh It is preceding that there is resource to service the request, then UE 102 sends an acknowledgement to MME 131, confirm period and triggering Location Request Received by UE 102 and is activated in UE 102.Otherwise, UE 102 can suitably error reason be returned to the transmission of MME 131 Errored response.The LCS period at stage 9, which triggers, calls message and any confirmation at the stage 10 can be as in 3GPP TS 24.080 It is defined.

At the stage 11, if UE 102 cannot support period and triggering Location Request, MME 131 can be suitable Error reason returns to the message (for example, user's positioning reporting message) comprising 142 address of LDR Ref. No. and H-GMLC V-GMLC 132.Otherwise, if UE 102 confirms in the stage 10 supports period and triggering Location Request, as the stage 11 Part, instruction event can be reported in UE 102 by MME 131 is activated and is included at the stage 3 received LDR with reference to compiling Number and 142 address H-GMLC message (for example, user's positioning reporting message) return to V-GMLC 132.If successor Report needs location estimation (for example, as indicated at the stage 3), then MME 131 can get the current location (example of UE 102 Such as, the stage 15 to 17 as described later) and can include in the message for being sent to V-GMLC 132 location estimation (for example, Which V-GMLC 132 can confirm to MME 131).As the part in stage 11, V-GMLC 132 is then via H-GMLC 142 And R-GMLC 152 to LCS client 160 return to LCS service response with notify in UE 102 whether activation cycle and triggering it is fixed Position request.It may include by H- when LCS service response is returned to part of the R-GMLC 152 as the stage 11 by H-GMLC 142 The LDR Ref. No. that GMLC 142 and 142 address H-GMLC are assigned, and the part R-GMLC 152 as the stage 11 can be in LCS LDR Ref. No. is transmitted to LCS client 160 in service response.Then, LCS client 160 can return a response to another Entity (for example, user of LCS client 160) (not shown in Fig. 2).As the part in stage 11, V-GMLC 132, H-GMLC 142 and/or R-GMLC 152 also can record the charge information of the request.After the stage 11, MME 131 and V-GMLC 132 It releasably include all resources about the request of any status information.Note that user's positioning reporting message and have it is upper Face can respectively correspond to previously for the LCS service response for the activation instruction that the stage 11 describes for two of fisrt feature reference Both the in response, including (such as and can be to LCS client back to LCS client by two intermediate responses by network 160 confirmations have started to position (or locating events) report in UE 102).User's positioning reporting message and correlation at stage 11 Connection confirmation message can be defined such as the EPC LCS agreement (ELP) in 3GPP TS 29.172.

At the stage 12, for zone issue or motion event, UE 102 is received in 9 place of stage to be equal to or less than The interval in maximum event sampling interval monitors institute's request event (or trigger event).If being not received by most major issue in the stage 9 The part sampling interval (for example, due to by LCS client 160 not including or part as the stage 2 is by H-GMLC at the stage 1 142 include), the maximum event sampling interval of default can be used in UE 102.It can using the maximum event sampling interval at the stage 12 Corresponding third feature previously described in this article, including maximum event sampling interval, and may make and can limit or reduce For 102 power of UE of event monitor and/or the limitation of battery consumption and the maximum delay to detecting event, such as previous institute Description.When following any situation occurs, event (or trigger event) can be detected in UE 102: (i) UE 102 has been detected To requested zone issue (for example, entering in region, being left from region or in region) or requested motion event, and from Final report (FR) (if this is not first event report) from the stage 14 has pass by minimum report interval (if the stage of being included in At 9)；(ii) requested regular positioning event has occurred；Or (iii) zone issue or the maximum report interval of action event have arrived Phase.Corresponding to alternative solution (iii) event trigger and its then it is associated with the stage 13 to 24 further describe it is subsequent Report can support period and the touching previously for the report of event described in the second feature of this program, including being directed to trigger event The maximum report interval of Location Request is sent out, and may make network entity (for example, R-GMLC 152 and H-GMLC 142) and LCS visitor Still effectively whether family end 160 can determine period and triggering positioning reporting in UE 102.

When detecting event triggers UE at the stage 12, once UE 102 can be to report PLMN's received at the stage 9 PLMN in optional list registers (for example, using RAN 120), or if do not provide the list of any report PLMN, or such as Fruit UE 102 does not support the optional list of report PLMN, then registering to original service PLMN, UE 102 proceeds to the stage 13. If UE 102 cannot be registered to licensed PLMN, UE 102 be may wait for until can access licensed PLMN to report The event is accused, or for period and triggering Location Request due to the cancellation of LCS client 160, the cancellation or permission of UE 102 The report duration expire and terminate.Note that if UE 102 carrys out the hair of report area event using different service PLMN It is raw, then UE 102 still can be continued to use by the original service containing cell ID and/or TA for original service PLMN The target area that PLMN (for example, being in this example VPLMN EPC 130) is provided.It may using only the limitation of licensed PLMN The PLMN carried out by UE 102 selection is not influenced.

At the stage 13, if UE 102 is in idle (for example, ECM-IDLE) state, UE touching is can be performed in UE 102 The service request of hair or connection restore (for example, as defined in 3GPP TS 23.401), to obtain signaling via RAN 120 Connection is to service MME 131.Note that the MME 131 and V-GMLC 132 in stage 13 to 24 can be with the MME 131 in stage 1 to 11 And V-GMLC 132 is different, but still can belong to VPLMN EPC 130.In period and another example (Fig. 2 of triggering Location Request In do not show) in, UE 102 can be attached to another PLMN EPC different from VPLMN EPC 130 at the stage 13, described Under situation, use can be replaced in MME 131 demonstrated in Figure 2, V-GMLC 132 and E-SMLC 133 for the stage 13 to 24 In MME, V-GMLC and E-SMLC of this other PLMN.For example, UE 102 can be attached in system architecture 100 via RAN 126 VPLMN EPC 134, in this situation in Fig. 2 show be used for the stage 13 to 24 MME 131, V-GMLC 132 and E- SMLC 133 can replace with MME 135, V-GMLC 137 and E-SMLC 136 respectively.If UE 102 cannot after the stage 12 It accesses VPLMN EPC 130 (for example, if UE 102 is not in coverage area of RAN 120) but has access to other PLMN (for example, due to having access to VPLMN EPC134 in the coverage area of RAN 126), it would be possible that occurring to another PLMN's This attachment.

At the stage 14, UE 102 can send the instruction extension period to MME 131 and trigger the event report of Location Request LCS mobile originating Location Request (MO-LR) call message.It may include the class of reported event that LCS MO-LR, which calls message, Type (for example, entering in region, left from region, in region, periodic event, motion event or maximum report interval phase It is full), LDR Ref. No., 142 address H-GMLC and whether need location estimation.When needing location estimation (for example, for Period locating events or for zone issue or motion event, if requested by LCS client 160), UE 102 may include in rank 9 received any QoS of section and location estimation (if location estimation is currently available for UE 102).UE 102 may further indicate that the period And whether triggering Location Request terminates in UE 102 now (for example, since the report duration expires or because only requests one A event report).Note that UE 102 provides location estimation in the stage 14 and can apply in some respects when requesting at the stage 9 In the expired event of the maximum report interval for corresponding to zone issue or motion event.In the LCS MO-LR tune that the stage 14 sends With message and return the result message for LCS MO-LR described in the stage 18 later can be as determined in 3GPP TS 24.080 Justice.

UE 102 maximum report interval expire when or before the stage 14 send LCS MO-LR call message the case where Under (for example, because after the stage 12 UE 102 be powered down or cannot access the PLMN of VPLMN EPC 130 or another permission), One or more of LCS client 160, H-GMLC 142 or R-GMLC 152 can determine UE 102 due in maximum report interval The MT-LR of period and triggering is not responded to and can no longer support before.In this scene (not shown in Fig. 2), LCS client End 160, H-GMLC 142 and/or R-GMLC 152 can cancel cycle and triggering Location Request-for example, it is as follows about Described by Fig. 3 and 4.

Fig. 2 is returned to, if the instruction of UE 102 needs location estimation at the stage 14, MME 131 can be by the stage The positioning of UE 102 is initiated by E-SMLC 133 is sent to the locating request message of UE 102 at 15.Then, E-SMLC 133 can be used control plane positioning solution in the positioning of the acquisition of stage 16 UE 102, as described earlier in this article.Example Such as, E-SMLC 133 can at the stage 16 with 102 exchanging orientation protocol message of UE (for example, about in 3GPP TS 36.355 The message of defined LTE location protocol (LPP)) (not shown in Fig. 2) and/or can at the stage 16 in RAN 120 with In UE 102 service eNB (such as eNB 122) exchanging orientation protocol message (for example, about the institute in 3GPP TS 36.455 LPP A (LPPa) agreement of definition) (not shown in Fig. 2).Location protocol message can be via MME 131 and (for example, being directed to LPP Message) it is exchanged via RAN 120.Location protocol message (for example, LPP message) can be used to request and receive and in E-SMLC 133 Alignment measurement (for example, being positioned for A-GNSS, OTDOA, E-CID or WLAN) and/or usable positioning association from UE 102 Message (for example, LPPa message) is discussed to request and receive alignment measurement from the service eNB (such as eNB 122) for UE 102 (for example, being positioned for E-CID).Also location protocol message (for example, LPP message) can be used to mention to UE 102 for E-SMLC 133 For auxiliary data to help to enable UE 102 to obtain position measurement (for example, for A-GNSS, OTDOA, E-CID or WLAN Position) and location estimation may be calculated from these alignment measurements.Then, E-SMLC 133 can be from the received position measurements of institute (for example, according to A-GNSS, OTDOA, E-CID or WLAN location method) determines the location estimation of (or verifying) UE 102, and can Location estimation is returned into MME 131 at the stage 17.If UE 102 provides location estimation, MME at the stage 14 It 131 can omit the stage 15 to 17 (for example, depending on configuration information in MME 131) or step 15 to 17 can be performed in MME 131 It and may include being estimated at the stage 14 by the positioning that UE 102 is provided in be sent to the Location Request of E-SMLC 133 in the stage 15 Meter.

At the stage 18, MME 131 sends MO-LR to UE 102 and returns the result message, and confirmation will send locating events report It accuses.If MME 131 cannot send locating events report (for example, because MME 131 does not support this ability), can return to MO-LR returns to mistake rather than UE 102 (not showing in Fig. 2).Then, UE 102 can define this MO-LR return mistake receiving Number embodiment after the last cycle and triggering finder.

Assuming that MME 131 can send locating events report, then at the stage 19, (the example in consolidated network of MME 131 Such as, in VPLMN EPC 130) select V-GMLC 132 and by message (such as user's positioning reporting message) together with the following terms Be sent to V-GMLC 132: the instruction of the event type (or locating events) of report (for example, enter in region, from region from Open, in region, periodic event, motion event or maximum report interval expire), LDR Ref. No., 142 ground H-GMLC Location, the stage 14 it is received or the stage 15 to 17 obtain any location estimation, and optionally about be used for location estimation Localization method information.MME 131 also may include UE 102 IMSI or MSISDN, and can indicate the MT-LR of period and triggering Now whether in UE 102 terminate (for example, if being indicated so in the stage 14 by UE 102).

At the stage 20, V-GMLC 132 will confirm that message is sent to MME 131, and MME 131 can record charge information. User's positioning reporting message at the stage 19 and the confirmation message at the stage 20 can be as defined for ELP agreement.

At the stage 21, V-GMLC 132 will be forwarded to H-GMLC 142 in the received information of stage 19, such as by rank 19 received 142 address H-GMLC of institute of section is identified.V-GMLC 132 can record charge information.

At the stage 22,142 use of H-GMLC is in the received LDR Ref. No. of 21 institute of stage and/or IMSI or MSISDN To identify the Location Request applied by the received message in 21 place of stage.H-GMLC 142 can also execute privacy at the stage 22 It checks (for example, it may be determined that whether at the stage 23 will be forwarded to LCS client 160 in the received information of the institute of stage 21).

At the stage 23, H-GMLC 142 will be forwarded to R- from the received information of V-GMLC 132 in LCS service response GMLC 152.If UE 102 instruction terminate Location Request, can in H-GMLC 142 MT-LR of execution cycle and triggering Location Request.H-GMLC 142 can record charge information.

At the stage 24, R-GMLC 152 reports event and any included location estimation is transmitted to LCS client 160.Then, LCS client 160 can report event and any included position is transmitted to another entity (for example, LCS is objective The user at family end 160) (not shown in Fig. 2).If UE 102 indicates the termination of the MT-LR Location Request of period and triggering, that Location Request can be completed in R-GMLC 152.R-GMLC 152 can record charge information.Note that working as R-GMLC 152 and H- It when GMLC 142 is identical, can omit the stage 23, and when H-GMLC 142 is identical as V-GMLC 132, the stage 21 can be omitted.

At the stage 25, if UE 102 is no after the stage 18 to terminate Location Request, UE 102 can be such as in rank Continue to monitor institute's request event at section 12, and can report each generation of institute's request event at the stage 13 to 24, until being asked The duration is asked to expire or until UE 102 or LCS client 160 terminate report for other reasons.

The explanation of signaling process 300 that Fig. 3 is shown when LCS client 160 requests to cancel for cancelling to period and triggering The program of the extension Location Request of positioning.For signaling process 300 it is assumed that being directed to UE described by signaling process 200 as being directed to 102 successfully start period and triggering MT-LR and the stage 1 to 7 or stage 1 to 11 and stage of successful execution signaling process 200 Possibility some events in 12 to 24.

At the stage 1 of signaling process 300, LCS client 160 requests to cancel the period of previous Request and the MT- of triggering LR Location Request.The LDR (or other) in the previous LCS service response of LCS client 160 included is sent to by R-GMLC 152 Ref. No. (for example, such as at the stage 7 of signaling process 200 or stage 11) may include in 1 place of stage of signaling process 300 Which should be cancelled with instruction in the request of transmission and carrying out Location Request.

At the stage 2, cancellation request is sent H-GMLC 142 by R-GMLC 152, includes LDR Ref. No..Some In scene (showing in Fig. 3), R-GMLC 152, which itself can be originated, to be cancelled, such as whenever R-GMLC 152 is from there is no positioning reports It accuses up to long-term and infers that Location Request may be terminated by UE 102.

In the stage 3, H-GMLC 142 can send message (example to HLR/HSS 144 using the IMSI or MSISDN of UE 102 Such as, SEND_ROUTING_INFO_FOR_LCS message) to inquire the current VPLMN of UE 102.If UE 102 is no longer by original V-PLMN EPC 130 or original MME 131 is serviced, it would be possible that needing said circumstances.

At the stage 4, HLR/HSS 144 returns to 132 address of 131 address current service MME and V-GMLC of UE 102. Note that the stage 4 by the MME 131 indicated and V-GMLC 132 of HLR/HSS 144 can with it is initial in the MT-LR of period and triggering It is different for the original MME 131 and V-GMLC in stage 1 to 11 132 in signaling process 200 when beginning.

At the stage 5, H-GMLC 142 by LCS cancel service request with from the received LDR Ref. No. of R-GMLC 152, 142 address H-GMLC services 131 address MME (for example, receiving at step 4 from HLR/HSS144) and is possibly used for UE 102 IMSI or MSISDN is forwarded to V-GMLC 132 together.In some scenes (showing in Fig. 3), H-GMLC 142 can Itself starting cancelbot is (for example, in the privacy profile for UE 102 being stored in H-GMLC 142 no longer to allow LCS When the reception of client 160 changes for the event of UE 102 and the mode of positioning reporting).

At the stage 6, V-GMLC 132 will indicate the cancellation of extension Location Request and be included in the stage 5 from H-GMLC 142 The message of 142 address of received LDR Ref. No. and H-GMLC (and may UE 102 IMSI or MSISDN) (such as provides use Family locating request message) it is sent to service MME 131.Even if when V-GMLC 132 be not involved in establish Location Request (for example, according to Signaling process 200) when, V-GMLC 132 is also to transmit canceling position.Offer user positioning request message at the stage 6 and slightly It afterwards can be as defined for EPC protocol for the described user's Relocation Commit message that provides of stage 10.

At the stage 7, if UE 102 is current unreachable (for example, during eDRX period or in PSM), MME 131 may wait for becoming reachable until UE 102.When UE 102 become up to when, if UE 102 be in idle state (for example, ECM-IDLE state) when, then MME 131 executes paging, verifying and encryption.

At the stage 8, the LCS period is positioned cancel request message (comprising LDR Ref. No. and optional H- by MME 131 142 address GMLC) it is sent to UE 102.

At the stage 9,102 dwelling period of UE and triggering locating events are reported and position the LCS period and cancel confirmation message Back to MME 131.Return the LCS period position cancellation confirmation can in addition when UE 102 does not know that finder is cancelled (example Such as, if UE 102 is powered off during program) Shi Yingyong.The LCS period at the stage 8 positioned cancellation request and at the stage 9 The LCS period positions cancellation confirmation message can be as defined in 3GPP TS 24.080.

At the stage 10, MME 131 will cancel confirmation and be sent to V-GMLC 132 (for example, providing user's positioning confirmation In message), and optionally there is 142 address of LDR Ref. No. and H-GMLC.In aspect, if MME 131 cannot be executed Stage 7 to 9 is (for example, since UE 102 changes MME 131 or VPLMN, or because stage of the MME 131 in signaling process 200 At 8 never in UE 102 activation cycle and triggering MT-LR), MME 131 can suitable error reason return to errored response (for example, user location error response message is provided).In in this regard, then mistake is returned to H-GMLC by V-GMLC 132 142, if applicable, H-GMLC 142 can retry cancellation with different MME 131 or different PLMN.

At the stage 11, LCS cancellation service response message is sent H-GMLC 142 by V-GMLC 132, and optionally has There is 142 address of LDR Ref. No. and H-GMLC.

At the stage 12, LCS cancellation service response message is sent R-GMLC 152 by H-GMLC 142, and optionally has There is LDR Ref. No..

At the stage 13, LCS cancellation service response is sent LCS client 160 by R-GMLC 152.

Fig. 4 shows the signaling process of the program for cancelling period and triggering positioning when UE 102 requests to cancel 400.If network entity (for example, H-GMLC 142, V-GMLC 132 or MME 131) cancels period and triggering positioning, It can be used for cancelling period and triggering positioning towards UE 102 above with respect to program described in signaling process 300, and be used for letter Enable the program of process 400 can be used for cancelling towards LCS client 160 period and triggering positioning.It is false for signaling process 400 If as successfully started period and triggering MT-LR and successful execution signaling flow for UE 102 for signaling process 200 is described The stage 1 to 11 of journey 200 and some generations of possibility in the stage 12 to 24.

Stage 1 in signaling process 400, UE 102 are waited until UE 102 is registered or can be in the rank of signaling process 200 (for example, via RAN 120) is registered to PLMN in the optional list of received report PLMN at section 9, or if not to UE 102 provide the optional list of report PLMN or if UE 102 does not support the optional list of report PLMN, are directed to signaling flow Journey 200 services PLMN (for example, VPLMN EPC 130) registration to dying with injustice unredressed.If UE 102 is in idle state (for example, ECM- IDLE state), then the service request of UE triggering can be performed by UE 102 or connection restores (for example, as in 3GPP TS 23.401 It is defined), to acquire the signaling connection of service MME 131.It should be noted that MME 131, RAN 120 demonstrated in Figure 4 And V-GMLC 132 may differ from the MME for establishing period and trigger position at the stage 1 to 11 in signaling process 200 131, RAN 120 and V-GMLC 132.

At the stage 2, UE 102 to service MME 131 send LCS MO-LR call message for cancelling for the period and Trigger the extension MT-LR of positioning.This message includes to terminate reason (for example, instruction user's terminator) and UE 102 in signaling Received 142 address H-GMLC and LDR Ref. No. at stage 9 in process 200.

In the stage 3, cancellation request can be sent to V-GMLC 132 from MME 131, and may include 142 address H-GMLC, The mark (for example, IMSI or MSISDN) of LDR Ref. No. and UE 102.V-GMLC 132 can be by the determination of MME 131-for example Based on the configuration information in MME 131.

At the stage 4 to 6, cancellation request may pass to H-GMLC 142, the R-GMLC of serve LCS clients 160 152, and it is ultimately delivered to LCS client 160.

At the stage 7 to 10, the response from LCS client 160 is transmitted back to MME 131 to confirm and cancel.

At the stage 11, MME 131 is returned the result in LCS MO-LR and is will confirm that in message back to UE 102.In the stage 2 Place send LCS MO-LR call message and the stage 11 send LCS MO-LR return the result message can be such as 3GPP TS Defined in 24.080.

In signaling process 200 starting for the period of UE 102 and triggering Location Request and in signaling process 300 and Cancel the ongoing period for UE 102 in 400 and triggers the previous case of Location Request based on the exemplary system of Fig. 1 System framework 100, wherein RAN 120 and RAN 126 provides the wireless access to UE 102 using NB-IoT or LTE RAT, and Wherein VPLMN EPC 130 and VPLMN EPC 134 supports the E-UTRAN of UE 102 using RAN 120 and RAN 126 respectively Access.However, signaling process similar or identical can with signaling process 200,300 and 400 for other RAT and other networks It can be possible.In an example embodiments, RAN 120 and RAN 126 in Fig. 1 can respectively replace with next-generation RAN (NG-RAN), the next generation RAN provides the wireless access to UE 102 according to NR or 5G.In this embodiment, VPLMN EPC 130 and VPLMN EPC 134 can respectively replace with 5G core network (5GC), wherein access and mobile management function to ps domain (AMF) can Each of MME 131,131# and 135 are replaced, orientation management function (LMF) is alternatively in E-SMLC 133,133# and 136 Each, and V-GMLC 132,132# and 137 can keep being not replaced or can be by the identical name entity of execution similar functions Replacement.It then, can be by being replaced to the MME in these signaling processes with the reference to AMF to each ginseng of 131,131# or 135 Examine, with to LMF reference replacement to E-SMLC 133,133# or 136 it is each with reference to and with to gNB reference replacement to eNB (for example, eNB's 122 or 124) is each with reference to creating the signaling similar or almost the same with signaling process 200,300 and 400 Process.It then, can also be by being replaced to the MME in these signaling processes with the reference to LMF to each of 131,131# or 135 With reference to the reference replacement to LMF (it can be the identical LMF of replacement MME) to E-SMLC 133,133# or 136 each ginseng It examines, the stage 15 and 17 in removal signaling process 200 (are retouched so that LMF is able to carry out for the MME in signaling process 200 The some functions of stating), and with reference replacement to gNB to each with reference to creating and believe of eNB (for example, eNB 122 or 124) Enable process 200,300 and 400 similar signaling processes.When UE uses NR rather than NB-IoT or LTE is used to carry out wireless access, The signaling process of modification can be defined for the program that period and triggering positioning are executed for UE 102.

Fig. 5 shows the place for executing the period to target UE (such as UE 102) and triggering the method for positioning service Manage process 500.Process flow 500 can be executed by first network entity.First network entity can be MME (for example, system architecture MME 131, MME 131# or MME 135 in 100), any of AMF or LMF.In following process flow 500 In description, it can correspond in the signaling process 200 modified as described above by the reference to movement that AMF or LMF is executed One or more stages, to be suitable for the 102 NR wireless access of UE via NG-RAN to 5GC.

Process flow 500 can start at frame 502, and wherein first network entity receives from the second network entity and is directed to target The period of user equipment (for example, UE 102) and triggering Location Request.Second network entity can be Gateway Mobile Location Center (GMLC).For example, the second network entity can be V-GMLC (such as V-GMLC 132) or H-GMLC (such as H-GMLC 142), and Frame 502 can correspond to the stage 3 in signaling process 200.For example, period and triggering Location Request can correspond to provide user's positioning Request message.

At frame 504, first network entity emits the instruction period to the second network entity and triggering Location Request has been connect It receives and received first responds.For example, the first response can correspond to provide user's Relocation Commit message, and frame 504 can correspond to Stage 4 in signaling process 200.

At frame 506, if target UE is not currently in reachable state, first network entity waits target to use Family equipment and wireless network (for example, VPLMN EPC 130 and RAN 120) are in reachable state.For example, frame 506 can correspond to The part in the stage 8 in signaling process 200.
