Background technology

Fig. 1 is that (The 3rd Generation Partnership Project, third generation affiliate counts 3GPP Draw) honeycomb moves long evolving system in family's standard (Long Term Evolution is called for short LTE) System architecture schematic diagram, including mobile management entity (the Mobility Management of core-network side Entity, is called for short MME), gateway (Serving GetWay is called for short SGW), wireless access The subscriber equipment of net side or referred to as terminal (User Equipment, be called for short UE) and base station (eNodeB, Referred to as eNB), it is Uu air interface between them or is referred to as eating dishes without rice or wine, between eNB and MME be S1-MME (S1for the control plane) terrestrial interface, is S1-U ground between eNB and SGW Face interface, is X2-U (X2-User plane) and X2-C (X2-Control plane) between eNB Face interface.

Fig. 2 (a)～Fig. 2 (d) is UE and eNB in LTE system, core net (MME and SGW) Between chain of command and the protocol stack architecture in user face, and chain of command and user face between eNB and eNB Protocol stack architecture schematic diagram.Uu therein eat dishes without rice or wine media access control layer (Media Access Control, Be called for short MAC) and physical layer (Physical layer, abbreviation PHY) agreement be subsequent content weight of the present invention The part that point is relevant.MAC layer be mainly upper level logical channels provide data transmission and be responsible for up-downgoing without The distribution of line resource, completes hybrid automatic repeat-request (Hybrid ARQ is called for short HARQ), scheduling (Scheduling), the merit such as priority processing and multiplexing and demultiplexing (Multiplexing is called for short MUX) Energy；PHY layer is mainly the packet MAC PDU of transmission channel provides physical layer coherent signal to process, Transmission means and signal conversion of eating dishes without rice or wine.Additionally Uu eat dishes without rice or wine upper strata agreement RLC (Radio Link Control, Wireless spread-spectrum technology) layer is mainly used in providing user and controlling the segmentation of data and retransmission service；PDCP Layer is mainly used in completing the transmission of user data to RRC or upper strata, user face；Rrc layer has been mainly used in Become broadcast (Broadcast), paging (Paging), wireless heterogeneous networks connection management, radio bearer Control, mobility functions, terminal survey report and control etc..Above-mentioned background technology is at the open net of 3GPP The associated protocol specification of LTE all can be inquired in standing.

Special equipment is utilized to carry out cost and the complexity of artificial network's drive test in order to reduce mobile operator, LTE system, from the beginning of Rel-10 version, introduces and a series of minimizes drive test (Minimization of Drive Test, referred to as MDT) function.MDT utilizes common LTE terminal automatic collection network phase The measurement result closed, is then reported to eNB by chain of command (Control Plane) signaling, then is passed through The terrestrial interface of eNB upstream is reported further to Operation & Maintenance System (Operation And Maintenance, referred to as OAM) tracking collect entity (Trace Collection Entity, be called for short For TCE), for network design and the adjusting and optimizing of operational factor.Such as: MDT it can be found that certain The weak covering of a little network areas, blind spot problem, can find that some has hot spot region of Large Copacity demand etc..

MDT function is divided into MDT (Management based MDT) based on management and based on signaling MDT (Signaling based MDT).The activation process of MDT based on management is typically OAM Send and comprise the tracking activate message (Trace session activation) of MDT configuration to eNB, eNB Suitable UE is selected in the region (MDT Valid Area) that this message specifies, and by described MDT Configuration information is sent to the UE chosen.The activation process of MDT based on signaling is to be sent bag by OAM Tracking activate message (Trace session activation) containing MDT configuration gives home subscriber server (Home Subscriber Server, referred to as location register (HSS)) specifies UE's to activate MDT measures, and the MDT configuration information of described UE is sent to MME by location register (HSS), The MDT configuration information of this UE is sent to eNB, eNB MDT configuration information the most at last and sends out by MME Give this UE.MDT based on signaling is generally with IMSI International Mobile Subscriber Identity (International Mobile Subscriber Identity, referred to as IMSI) or international mobile station device identification (International Mobile Station Equipment Identity, referred to as IMEI) specify certain UE, or plus area information To limit the selection of UE.MDT based on management and tracking activate message based on signaling all comprise From track reference (Trace Reference) information of OAM, wherein, including PLMN Network (Public Land Mobile Network, referred to as PLMN) information, by Mobile Country Code MCC (Mobile Country code, referred to as MCC) and Mobile Network Code (Mobile Network code, referred to as MNC) composition.

MDT function is operated in Idle state RRC_IDLE according to it and is operated in connected state RRC_CONNECTED can be divided into two kinds of mode of operations, and specially " record minimizes drive test (Logged MDT) " and " minimizing drive test (immediate MDT) immediately ".Record minimum Change drive test to refer to: UE receives when the condition configured meets in RRC_IDLE (RRC is idle) state Report when collecting and store correlation measurement information for receiving and ask for order request from eNB in the future, eNBs After receiving data, collect or be directly forwarded to TCE.Minimize drive test immediately and refer to that UE exists During RRC_CONNECTED (RRC connection) state, collect correlation measurement information and meet in report During report condition, active upload is to eNB, and then collects report is passed to TCE.

The different attribute of object is measured according to MDT, can be in the measurement object of current LTE MDT Hold and be divided into 3 classes or 3 layers: L1: such as, to LTE descending pilot frequency class signal (Common Reference Signal, public reference signal, is called for short CRS；Channel State Information-Reference Signal, Channel status instruction reference signal, is called for short CSI-RS) intensity RSRP (Reference Signal Receiving Power, Reference Signal Received Power) and quality RSRQ (Reference Signal Receiving Quality, Reference Signal Received Quality) statistics of variables measurement；L2: such as, to LTE MAC/RLC (Radio Link Control, wireless spread-spectrum technology)/PDCP (Packet Data Convergence Protocol, packet count According to convergence protocol) etc. Protocol layer data packet delay/packet loss/packet loss statistics of variables measure；L3: such as, To LTE particular data radio bearer (Data Radio Bearer is called for short DRB) data throughput/handle up Amount and the statistical measurement of other mobility correlated performances (switching, call drop etc.) index.

Up to now, the measurement object of MDT is essentially from the content in operator's belonging network, as belonged to The pilot signal quality of oneself network service district and intensity, capacity regionality distribution configures, to one's name Miscellaneous service QOS (Quality of Service, the service quality) performance of service UE in network.This Fill in authorizing frequency spectrum wireless environment and want, because authorizing frequency spectrum to mean only to spend have purchased its fortune Battalion business, just has the right to determine the most specifically to go to dispose to use and those mandate frequency spectrum resources of adjusting and optimizing.Remove Outside mandate frequency spectrum, medium-high frequency section also have a large amount of unlicensed spectrum resource (operator need not buy, Multiple operators can freely dispose use under the restriction of public wireless control condition), such as run Business and enterprise's household person dispose WLAN WLAN AP (access node) node used Make use of these unlicensed spectrum resources to carry out up-downgoing data transmission, following LTE evolution system is also in addition The technology such as LAA (Licensed Assisted Access authorizes and assists to access) can be utilized to remove connection further Closing polymerization utilizes these unlicensed spectrum resources to carry out the transmission of up-downgoing data, this external unlicensed spectrum In, it is also possible to or without the Non-LAA Standalone LTE-U system authorizing carrier wave to assist, the most various The wireless systems such as radar microwave navigation, these adhere to the different types of wireless system of different operators separately with not Same compound mode coexists in unlicensed spectrum wireless environment, causes the wireless environment of complex and does Disturb situation.

In view of present situation, if certain operator A needs with specific system mode, go to utilize certain physical areas Unlicensed spectrum resource in territory and band limits, if it is possible to the in advance and in real time wireless environment to it Carrying out perception understanding, this is highly profitable undoubtedly.Although co-existing in same target physical region and band limits The interior different system of different operator, they the most specifically dispose and use identical unlicensed spectrum resource mode Method cannot be predicted by operator A, i.e. has a potential, uncontrolled property and the feature of randomness, but Being to measure sampling by substantial amounts of MDT and report statistical information, operator A is it is also possible that analyze Certain rule, and then preferably dispose and use unlicensed spectrum resource to provide valuable ginseng for follow-up Examine.

Owing to the respective server carrier/cell deployment of current vast operator is authorizing on frequency spectrum, existing MDT technology can't carry out relevant MDT and measure and knot the carrier wave/Serving cell in unlicensed spectrum Fruit collects statistics, does not also have carrier wave RSSI simultaneously or receives the measurement of correlation statistics of gross energy index amount.

Detailed description of the invention

Given this meaning, embodiments provides a kind of method knowing unlicensed spectrum wireless environment.

Fig. 3 is the flow chart of the method knowing unlicensed spectrum wireless environment of the embodiment of the present invention, such as figure Shown in 1, the method for the present embodiment includes:

S0: initializing, LTE network and terminal UE are all provided simultaneously with the GL of the present invention, UE It is among the unlicensed spectrum environment under the covering of LTE network normal wireless and described in background technology.

Whether S1:OAM/TCE judges that unlicensed spectrum resource uses and is satisfied with, if will start or continue MDT measures the flow process of unlicensed spectrum wireless environment, as wireless in MDT to be started measurement unlicensed spectrum The flow process of environment, then go to step S2, as being not required to start, then returns to init state.

Unlicensed spectrum in the present embodiment refers to had specific center frequency point and certain band by one or more Wide frequency band, carrier wave or community synthesis.

OAM/TCE analyzes module analysis through internal specific unlicensed spectrum resource service condition and sends out Existing: within a period of time in past, non-in the range of this of the UEs that services certain eNB administrative area in Authorize frequency spectrum resource service condition undesirable/dissatisfied/the most up to standard, then determine that starting MDT measures non- Authorize the flow process of frequency spectrum wireless environment.

This step is optional.

S2:OAM/MME/TCE starts MDT and measures the flow process of unlicensed spectrum wireless environment.

OAM/MME/TCE passes through the control message on terrestrial interface (such as S1 interface) " MDT Measure unlicensed spectrum wireless environment " order (startup) and relevant configured parameter (such as thing to be measured Reason regional extent, effective time limit, the unauthorized band limits of target, measure the cycle, measure object etc.) send out To the service eNB at UE place.

ENB passes through the control message in air interface further " it is wireless that MDT measures unlicensed spectrum Environment " order (startup) and relevant configured parameter (ibid) issue UE.Above-mentioned control message Send reception to be realized by LTE system existing chain of command data transmitting-receiving module.

S3:UE receives the order of " MDT measures unlicensed spectrum wireless environment " from eNB After relevant configured parameter, internal execution certain the type following measurement to unlicensed spectrum wireless environment, Can be realized by the internal unlicensed spectrum radio environment measurements module of UE.

Class1: UE is in RRC_IDLE state, then according to eNB configuration measurement physical extent and In the cycle, (can be configured multiple) in target unauthorized frequency range carrier frequency point and bandwidth, go to measure note Picture recording answers received signal strength indication value, and (Received Signal Strength Indicator is called for short RSSI), now RSSI value comprise that all symbiotic systems that UE currently can receive launch all dry Disturb the institutes such as signal summation, such as WLAN APs, LAA-LTE system, Standalone LTE-U system Some interference sources.Rssi measurement can utilize the DRX under RRC_IDLE state opportunity (Discontinuous Receive discontinuously receives) OFF Period (discontinuously receiving closed-down period).

Further, owing to WLAN AP can launch Beacon (beacon) pilot signal periodically, because of This UE also can be only relevant with WLAN AP Beacon under surveying record individually RSSI value.

Type 2:UE is in RRC_CONNECTED state, but the work in current unauthorized frequency range Make frequency and bandwidth (if being configured) and MDT target to be measured unauthorized frequency range carrier wave frequency range is not appointed What intersection, then according to measurement physical extent and the cycle of eNB configuration, carry in the unauthorized frequency range of target In ripple frequency and bandwidth (can be configured multiple), remove the signal intensity that surveying record is received accordingly Indicated value (Received Signal Strength Indicator is called for short RSSI), now RSSI value comprises All interference signal summations that all symbiotic systems that UE currently can receive are launched, such as WLAN The all of interference sources such as APs, LAA-LTE system, Standalone LTE-U system.During rssi measurement Machine can utilize under RRC_CONNECTED state configuration measurement space Measurement Gaps or Person DRX Inactive Period (discontinuous reception deexcitation closed-down period).

Further, owing to WLAN AP can launch Beacon pilot signal periodically, therefore UE is also RSSI value that can be only relevant with WLAN AP Beacon under surveying record individually.

Type 3:UE is in RRC_CONNECTED state, but the work in current unauthorized frequency range Make frequency and bandwidth (if being configured) and MDT target to be measured have the part completely or partially overlapped, Then according to measurement physical extent and cycle, the work in the unauthorized frequency range being currently configured of eNB configuration In frequency and bandwidth, remove signal strength indication value (the Received Signal that surveying record is received accordingly Strength Indicator, is called for short RSSI), now RSSI value comprise that UE currently can receive all All interference signal summations that symbiotic system is launched, such as WLAN APs, LAA-LTE system, The all of interference sources such as Standalone LTE-U system.Rssi measurement can utilize opportunity Measurement space Measurement Gaps or DRX of configuration under RRC_CONNECTED state Inactive Period.Type 2 and type 3 can be compatible, can be the most measured.

Further, owing to WLAN AP can launch Beacon pilot signal periodically, therefore UE is also RSSI value that can be only relevant with WLAN AP Beacon under surveying record individually.

S4: report the MDT measurement result of unlicensed spectrum wireless environment.

After UE performs in step S3 the measurement to unlicensed spectrum wireless environment, it is thus achieved that a series of MDT result data (at least contains: the corresponding moment measured on time dimension, corresponding survey in frequency dimension The unauthorized frequency bandwidth of amount, the corresponding physical location information measured on Spatial Dimension, measurement result is corresponding RSSI quantized value, then according to LTE system existing MDT result triggers and reporting schemes (passes through LTE system existing MDT measurement data reporting module realizes), go to report the most recorded unauthorized The result of frequency spectrum radio environment measurements, eNB reports TCE MDT measurement result the most again and collects Analyze.

After S5:OAM/TCE obtains the MDT data that UE records, generate unlicensed spectrum resource distribution Pattern.

Alternatively, OAM/TCE collects flow process by existing MDT measurement result, it is thus achieved that arrived multiple A series of MDT data that UEs recorded in past MDT Session (j), specific through inside Unlicensed spectrum wireless environment analyze module analysis find: some period/some physical location scope/certain In a little unauthorized frequency bandwidth, rssi measurement value (means the unauthorized money in there than relatively low/more stable Source is more idle), and in additionally some period/some physical location/some unauthorized frequency bandwidth, Rssi measurement value is the highest/(mean that the there occupied utilization rate of unauthorized resource compares than more random High) etc., therefore the wireless environment of unlicensed spectrum can be had necessarily based on regular cognition statistically, Thus generate unlicensed spectrum resource distribution pattern.

S6:OAM/TCE needs to analyze module through internal specific unlicensed spectrum resource service condition Continuing to analyze: within certain a period of time that the past is new, in certain eNB administrative area, the UEs of service is to this In the range of unlicensed spectrum resource service condition whether preferable/satisfied/up to standard etc.？Decide whether again to continue Or close MDT and measure the flow process of unlicensed spectrum wireless environment.Non-awarding is measured as decided to continue with MDT The flow process of power frequency spectrum wireless environment, the most heavily joins MDT and measures the flow process of unlicensed spectrum wireless environment.Fortune Battalion business can be according to rule, environment, the change of condition, measures entity for each MDT and goes again to join Put MDT parameter, thus obtain different MDT measurement result expectations.

OAM/MME/TCE passes through the control message on terrestrial interface such as S1 interface above-mentioned " unauthorized Frequency spectrum resource distribution pattern " issue the service eNB at UE place, thus eNB is follow-up to service UEs The when of carrying out unauthorized resource distribution and use, there is the ginseng in more preferable time/space/frequency dimension Examine.ENB can go to select at those unlicensed spectrum resource ratios as possible according to the consideration of internal comprehensive strategic Use in more idle time/space/frequency.

In step S3, UE can also surveying record carrier energy load indicated value etc.

Except RSSI and carrier energy load indicated value, it is also possible to comprise existing MDT technology for mandate All kinds of measurement amounts that frequency spectrum intercarrier community has been defined for, the MDT illustrated in such as background technology is Have and measure object and result quantities: L1/L2/L3 correlative.Embodiment is entered as a example by surveying record RSSI Row explanation.

Foregoing invention embodiment provides a kind of side being known unlicensed spectrum wireless environment by terminal measurement Method, takes the fundamental mechanism of MDT technology in LTE system.In principle, OAM/MME/TCE is same Sample can also allow eNB node go to measure the wireless environment knowing unlicensed spectrum, and without passing through further Chain of command flow process of eating dishes without rice or wine and terminal carry out that the transmission of MDT relevant configuration is mutual and the reporting of measurement result, Summary of the invention is equally applicable to allow eNB do the situation that MDT measures.But due to eNB it is the most all ratio Relatively fixed position is disposed, and therefore can only measure the unlicensed spectrum wireless ring around eNB fixed position Border, and what UE typically position was moved, that therefore can measure in the range of bigger and more dynamical non-awards Power frequency spectrum wireless environment, can be that network subsequent more reasonably disposes focus base station (Hotspot Small Cell) position and utilize the resource in unlicensed spectrum to provide more preferable reference.

Additionally, when execution UE is by the MDT measurement result about unlicensed spectrum wireless environment, pass through Eating dishes without rice or wine after Uu reports eNB, eNB can also be local the most in addition with reference to utilizing, and without entering one Walk and transmitted toward the network node such as MME of upstream further by S1 terrestrial interface.ENB can also lead to Cross X2 terrestrial interface further toward adjacent other eNB nodes transmission, allow adjacent eNB receive those About local the most in addition with reference to utilizing after the MDT measurement result of unlicensed spectrum wireless environment.In a word, No matter terminal or eNB node can carry out the MDT about unlicensed spectrum wireless environment and measure, Its MDT measurement result obtained, both upstream can report further Macro or mass analysis to process by network node Utilize, it is also possible to behind this locality or transmission, Macro or mass analysis processes and utilizes.

For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing Embodiments of the invention are described in detail.It should be noted that in the case of not conflicting, this Shen Embodiment in please and the feature in embodiment can mutual combination in any.Should be appreciated that described herein Multiple specific embodiments, only in order to explain present disclosure, be not intended to limit the present invention is interior Hold.

Embodiment 1:

S100: operator A configures and performs Logged to the UE 1 of service under certain eNB administrative MDT operates, and is learnt by LTE existing wireless capability interaction flow: this UE1 supports this The ability that bright content is relevant.The UE 1 being in RRC_IDLE state (joins at the Serving cell that eNB is administrative Put on the mandate carrier wave of operator A) in move freely through, internal radio frequency module can support that measurement is arrived Radio conditions in specific unlicensed spectrum.

S101:OAM/TCE analyzes module through internal specific unlicensed spectrum resource service condition and divides Analysis finds: within a period of time in past, non-in some physical extent of the UEs of this eNB service Authorize frequency spectrum resource service condition undesirable: as the least in LAA data distribution proportional quantities, unauthorized resource Competition collision probability is big, then determines that starting terminal MDT measures the flow process of unlicensed spectrum wireless environment.
