Communication means involved in the embodiment of the present invention, it is intended to solve the prior art at the position for determining UE, need to send paging message to all base stations, interface-free resources is caused to waste larger technical problem.

It is described in detail below with specifically embodiment to how technical solution of the present invention and technical solution of the present invention solve above-mentioned technical problem.These specific embodiments can be combined with each other below, and the same or similar concept or process may be repeated no more in certain embodiments.

Fig. 5 is the signaling process figure of communication means embodiment one provided in an embodiment of the present invention.What is involved is equipments of the core network for the present embodiment by controller equiment paging UE, to save the detailed process of interface-free resources.As shown in figure 5, this method comprises the following steps:

S101: equipment of the core network sends query messages at least one controller equiment.

The mark of UE is carried in the query messages, the query messages are used to indicate at least one described controller equiment and determine whether the UE is located in the cell range of at least one controller equiment covering according to the mark of the UE.

Specifically, when equipment of the core network determines that the current business datum for having UE is to be transmitted, equipment of the core network sends query messages at least one controller equiment, optionally, at least one controller equiment can be all controller equiments for having interface with equipment of the core network, it can also be the segment controller equipment that equipment of the core network is screened from all controller equiments, and, at least one controller equiment can be the base station with controller function, it can also be the equipment independently of base station that there is communication interface with base station, such as the controller Controller in the network architecture of above-mentioned multiplexing, the present embodiment is at least one controller equiment and without limitation.Above-mentioned query messages are used to indicate at least one controller equiment according to UE Mark determine the UE whether be located at least one controller equiment covering cell range in, wherein, the mark of the UE, it can be international mobile subscriber identity (the International Mobile Subscriber Identification Number of UE, abbreviation IMSI) or Temporary Mobile Subscriber Identity (Serving-Temporary Mobile Subscriber Identity, abbreviation S-TMSI) or eNB be the UE distribution Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Cell Radio Network Temporary Identifier, abbreviation C-RNTI) Or controller equiment is the private link mark (Dedicated Connection Identifier, abbreviation DCID) of UE distribution, is also possible to other identifier, the present invention is without limitation.It should be noted that above-mentioned DCID is unique mark of the UE in hypercell,

S102: at least one controller equiment receives query messages.

S103: at least one controller equiment determines whether the UE is located in the cell range of at least one controller equiment covering according to the query messages.

Specifically, at least one controller equiment inquires whether UE is located in the cell range of its covering after receiving query messages, according to the query messages.Optionally, the accurate location of UE can be determined using the tracking signal that the interval UE received under a certain particular state is sent, specifically: in the nocell involved in the network architecture of multiplexing, there are two types of states by UE: ACTIVE state and ECO state, in ACTIVE state, UE can support schedule data transmission, what the UE (UE may be transmitted without business at this time) in ECO state can be spaced sends tracking (tracking) signal to the TP under at least one above-mentioned controller equiment, TP can be to affiliated controller equiment reporting measurement reports after receiving the tracking signal, based on this mechanism, at least one controller equiment can know whether UE corresponding to the mark of above-mentioned UE is located in the coverage area of itself.Optionally, above-mentioned " a certain specific state " can be the ECO state under the network architecture of multiplexing, which is actually the state under a kind of battery saving mode, and between Idle state and connected state, in this state, UE can send some signals to network side.

S104: when the first controller equiment determines that the UE is located in the cell range of itself covering, the first controller equiment sends confirmation message to the equipment of the core network；Wherein, the first controller equiment belongs at least one above-mentioned controller equiment.

Specifically, when the first controller equiment at least one controller equiment determines that UE is located in the cell range of itself covering, first controller equiment can send confirmation (ACK) message to equipment of the core network, to inform that equipment of the core network UE is located in the coverage area of the first controller equiment.

S105: equipment of the core network receives the confirmation message that the first controller equiment is sent.

The confirmation message is used to indicate the UE and is located in the cell range of first controller equiment covering.

Specifically, after equipment of the core network receives the confirmation message of the first controller equiment transmission, know that UE is located in the coverage area of the first controller equiment, that is equipment of the core network specific location that UE has been known that by the confirmation message, paging message (i.e. without paging UE in the cell that all base stations cover) is sent without all base stations in the TAI List to UE and is assured that the position of UE, thus interface-free resources when paging UE is greatly saved.

Optionally, if equipment of the core network does not receive any controller equiment and is directed to the confirmation message that query messages are replied, the paging method of the prior art is used, details are not described herein.Equipment of the core network mentioned here does not receive any controller equiment and is directed to the confirmation message that the query messages are replied, it can be all controller equiments for receiving query messages and all replied negative (NACK) message, it is also possible to equipment of the core network and starts a timer when sending query messages, confirmation message is still not received by timer expiry, so that equipment of the core network re-starts the transmission of query messages or the paging method using the prior art, the indefinite waiting of equipment of the core network is avoided.

Communication means provided in an embodiment of the present invention, query messages are sent at least one controller equiment by equipment of the core network, so that at least one controller equiment determines whether UE is located in the coverage area of itself according to the query messages, when the first controller equiment at least one controller equiment determines that UE is located in itself coverage area, confirmation message is sent to equipment of the core network, so that equipment of the core network knows the specific location of UE, therefore, equipment of the core network sends paging message without all base stations into the TAI List of UE, save interface-free resources when paging UE, improve the paging efficiency of UE.

Fig. 6 is the signaling process figure of communication means embodiment two provided in an embodiment of the present invention.What is involved is equipments of the core network after the confirmation message for receiving the transmission of the first controller equiment for the present embodiment, paging message is sent to the first controller equiment, so that the detailed process of UE access equipment of the core network.On the basis of the above embodiments, further, after above-mentioned S105, this method can also include:

S106: equipment of the core network sends paging message to the first controller equiment.

The mark of the UE is carried in the paging message, the paging message is used to indicate first controller equiment and initiates paging.

S107: the first controller equiment initiates paging according to the paging message.

In the present embodiment, equipment of the core network is after the confirmation message for receiving the transmission of the first controller equiment, know that UE is located in the coverage area of the first controller equiment, thus equipment of the core network sends the paging message for carrying UE and identifying to the first controller equiment, allows the first controller equiment to UE initiation paging so that UE accesses equipment of the core network after being transferred to activated state from Idle state.Optionally, it can be after equipment of the core network indicates that the first controller equiment sends paging message to UE, instruction UE is transferred to state of activation to the first controller equiment initiating random access procedure, that is, UE, then sends business datum to UE by the first controller equiment；Optionally, it can also be that the first controller equiment of instruction directly sends business datum to UE.Optionally, the first controller equiment can be independently of the equipment of base station in the present embodiment, such as can be controller (controller), or the base station with controller function.

Communication means provided in an embodiment of the present invention, equipment of the core network is after receiving confirmation message, paging message is sent to the first controller equiment by orientation, so that the first controller equiment UE initiates paging, UE is paged in cell without all base stations in the TAI List of UE, interface-free resources when paging are saved, paging efficiency is improved.

Fig. 7 is the flow diagram of communication means embodiment three provided in an embodiment of the present invention.The present embodiment selects to send query messages at least one controller equiment what is involved is equipment of the core network, with the detailed process for the interface resource saved between equipment of the core network and at least one controller equiment.On the basis of the above embodiments, further, before S101, this method can also include:

S201: at least one controller equiment sends tracing area identification information to equipment of the core network.

S202: equipment of the core network obtains the tracing area identification information of at least one controller equiment.

S203: when determining that the tracing area identification information of at least one controller equiment is matched with the TAI in the tracing area identification list of the UE when equipment of the core network, equipment of the core network, which is determined at least one controller equiment, sends the query messages.

Specifically, under the available equipment of the core network of equipment of the core network all controller equiments tracing area identification information, optionally, the TAI which can be used for characterizing these controller equiments and which base station has relationship.Therefore, after equipment of the core network receives these tracing area identification informations, determine that the TAI in the tracing area identification information of some of which controller equiment and the tracing area identification list (TAI List) of UE is matched, so equipment of the core network, which is determined to these controller equiments, sends query messages.It should be noted that " matching " mentioned here, can be controller equiment Tracing area identification information at least one TAI it is identical as the TAI in the tracing area identification list (TAI List) of UE.

Optionally, when at least one above-mentioned controller equiment is the equipment independently of base station, such as when Controller (equipment in following embodiments independently of base station is by taking Controller as an example), when TAI of the equipment of the core network in the TAI List of the tracing area identification information that at least one above-mentioned controller equiment has been determined and UE is matched, so that it may directly send query messages at least one controller equiment (i.e. an at least Controller).Further, before equipment of the core network sends query messages at least one Controller, equipment of the core network needs to establish the first communication interface with these Controller.The process for establishing the first communication interface can be equipment of the core network triggering, can also be that Controller is triggered.Also, the mode that above-mentioned equipment of the core network obtains the tracing area identification information of at least one controller equiment may include following several:

The first: step shown in Figure 8, above-mentioned S201 are specifically included:

S301:OAM is the TAI that Controller configures Controller.

S302:Controller and equipment of the core network establish the first communication interface, and when establishing the first communication interface, the TAI of the ID of Controller and Controller is sent to equipment of the core network.

Specifically, when establishing the first communication interface, it may is that Controller sends the first communication interface to equipment of the core network and establishes request message (step A), first communication interface establishes in request message the TAI for carrying the ID and Controller of Controller, equipment of the core network is after receiving the first communication interface and establishing request message, the first communication interface, which is sent, to Controller establishes response message (step B), first communication interface is successfully established, and the first communication interface shown in Figure 9 establishes signaling process figure one.It may also is that equipment of the core network, which sends the first communication interface to Controller, establishes request message (step A '), Controller is after receiving first communication interface and establishing request message, the TAI carrying of the ID of Controller and Controller is established in response message in the first communication interface and is sent to equipment of the core network (step B '), first communication interface is successfully established, and the first communication interface shown in Figure 10 establishes signaling process figure two.That is, the tracing area identification information of Controller is the TAI of the ID and Controller of Controller under the implementation, so that equipment of the core network can determine whether the Controller matches with the TAI in the TAI List of UE according to the ID and TAI of the Controller, and then determine that the matched Controller of TAI into the TAI List of TAI and UE sends query messages, save the interface resource between Controller and equipment of the core network.

Second: step shown in Figure 11, above-mentioned S201 are specifically included:

The second communication interface is established in S401:Controller and the second base station, and obtains when establishing the second communication interface the ID of the second base station and/or TAI of second base station.

Specifically, in this implementation, the tracing area identification information of Controller can be the ID of Controller and there are the ID of the second base station of the second communication interface with the Controller, it can also be the ID of Controller and the TAI of the second base station, can also be the ID of the ID of Controller, the TAI of the second base station and the second base station.

As the ID of ID and the second base station that the tracing area identification information of Controller is Controller, since equipment of the core network can know the ID of the second base station and TAI of the second base station by the interaction for carrying out information with the second base station, in this way when equipment of the core network get Controller ID and the second base station ID when, equipment of the core network can know that the Controller is relevant with which TAI, and then equipment of the core network checks whether the TAI List of UE includes the TAI again, if so, equipment of the core network, which is determined to the Controller, sends query messages.

As the TAI of ID and the second base station that the tracing area identification information of Controller is Controller, equipment of the core network is after getting the tracing area identification information of the Controller, it can directly know that the Controller is relevant with which TAI, and then equipment of the core network checks whether the TAI List of UE includes the TAI again, if so, equipment of the core network, which is determined to the Controller, sends query messages.

As the TAI of ID, the second base station that the tracing area identification information of Controller is Controller and the ID of the second base station, equipment of the core network is after getting the tracing area identification information of the Controller, it can also directly know that the Controller is relevant with which TAI, and then equipment of the core network checks whether the TAI List of UE includes the TAI again, if so, equipment of the core network, which is determined to the Controller, sends query messages.

Tracing area identification information based on the above different Controller, all refer to the relevant information to the second base station, therefore, the ID of the Controller and ID with the second base station are sent to equipment of the core network in Controller, or, the ID of the Controller and the TAI of the second base station are sent to equipment of the core network in Controller, or, the ID of the Controller is sent to equipment of the core network in Controller, before the TAI of the second base station and ID of the second base station, Controller needs to establish the second communication interface with the second base station, and the ID of the second base station and/or TAI of the second base station is obtained when establishing the second communication interface.When establishing the second communication interface, Controller triggering can be, it can also be with It is the second base station triggers.When establishing the second communication interface by Controller triggering, specifically: Controller sends the second communication interface to the second base station and establishes request message (step C), optionally, second communication interface establishes in request message the ID for carrying Controller, second base station is after receiving the second communication interface and establishing request message, the second communication interface, which is sent, to Controller establishes response message (step D), second communication interface establishes in response message the TAI of the ID for carrying the second base station and/or the second base station, second communication interface is successfully established, second communication interface shown in Figure 12 establishes signaling process figure one.When establishing the second communication interface by the second base station triggers, specifically: the second base station sends the second communication interface to Controller and establishes request message (step C '), second communication interface establishes in request message the TAI of the ID for carrying the second base station and/or the second base station, Controller is after receiving second communication interface and establishing request message, the second communication interface, which is sent, to the second base station establishes response message (step D '), optionally, second communication interface establishes in response message the ID that can carry Controller, second communication interface is successfully established, second communication interface shown in Figure 13 establishes signaling process figure two.

S402:Controller and equipment of the core network establish the first communication interface, and the ID of Controller and the ID of the second base station are sent to the equipment of the core network when establishing the first communication interface, or the ID of Controller and the TAI of the second base station are sent to equipment of the core network, alternatively, to equipment of the core network send Controller ID and the second base station TAI and the second base station ID.

Specifically, when Controller get the second base station ID and/or second base station TAI when, Controller and equipment of the core network establish the first communication interface, and when establishing the first communication interface by the ID of Controller obtained and, the TAI of the ID of the second base station and/or second base station is sent to equipment of the core network.

When Controller from establish obtained in the second communication interface process be the second base station ID, then Controller is when establishing the first communication interface with equipment of the core network, just by the equipment of the core network that is sent to of the ID of the Controller and ID of the second base station, i.e., the tracing area identification information for the Controller that equipment of the core network obtains at this time is the ID of Controller and the ID of the second base station；When Controller from establish obtained in the second communication interface process be the second base station TAI, then Controller is when establishing the first communication interface with equipment of the core network, just by the equipment of the core network that is sent to of the ID of the Controller and TAI of the second base station, i.e., the tracing area identification information for the Controller that equipment of the core network obtains at this time is the ID of Controller and the TAI of the second base station；When Controller is the TAI of the second base station and ID of the second base station from establishing obtain in the second communication interface process, then Controller exists When establishing the first communication interface with equipment of the core network, the ID of the ID of Controller, the TAI of the second base station and the second base station are just sent to equipment of the core network, i.e., ID, the TAI of the second base station and the ID of the second base station that the tracing area identification information for the Controller that equipment of the core network obtains at this time is Controller.

Above-mentioned Controller and equipment of the core network are when establishing the first communication interface, by the ID of Controller and, the ID of the second base station and/or TAI of second base station is sent to equipment of the core network (the tracing area identification information of Controller is sent to equipment of the core network), optionally, it can be Controller triggering and establish the first communication interface, specifically: Controller sends the first communication interface to equipment of the core network and establishes request message, first communication interface establishes in request message the tracing area identification information for carrying Controller, equipment of the core network is after receiving the first communication interface and establishing request message, the first communication interface, which is sent, to Controller establishes response message, it should First communication interface, which establishes response message, can carry the ID of equipment of the core network, and the first communication interface is successfully established.Optionally, it can also be that the first communication interface is established in equipment of the core network triggering, specifically: equipment of the core network sends the first communication interface to Controller and establishes request message, first communication interface, which establishes request message, can carry the ID of equipment of the core network, the tracing area identification information carrying of Controller is established in the first communication interface after receiving the first communication interface and establishing request message and is sent to equipment of the core network in response message by Controller.
