Abstract

The invention discloses a switching processing method and a switching processing system in a location service in a long term evolution network. In the scheme, when determining that user equipment (UE) needs to be switched in the process of initiating a service request, an evolved node B (eNB) sends a location control signaling containing a terminated location request to an enhanced serving mobile location centre (E-SMLC); and after receiving the location control signaling containing the terminated location request, the E-SMLC indicates the eNB or the UE to stop locating. According to the scheme, when determining that the UE needs to be switched in the process of initiating the service request, the eNB can send the location control signaling containing the terminated location request to the E-SMLC timely to stop locating, thereby avoiding the waste of location resources.

[0048]步骤 101 :eNB 向移动管理实体(MME,Mobility Management Entity)发送定位业务请求(Location Service Request),发起对UE 的定位。 [0048] Step 101: eNB sends a location service request (Location Service Request) to the mobile management entity (MME, Mobility Management Entity), the UE initiates positioning.

[0049] 步骤102 =MME收到来自eNB的定位业务请求后,向E-SMLC转发该定位业务请求。 After [0049] Step 102 = MME receives the positioning service request from the eNB, forwarding the request to the location service E-SMLC.

[0050] 步骤103a =E-SMLC收到定位业务请求后,进行与eNB交互的定位处理(eNB Procedures),如获取定位测量或辅助数据。 After [0050] Step 103a = E-SMLC receives location service request, the positioning process interaction eNB (eNB Procedures), such as obtaining positioning measurements or auxiliary data.

[0054] 以上流程中,eNB作为定位业务请求的发起方,主要是为了了解当前小区的信号情况,便于网络优化。 [0054] In the above process, the eNB as the positioning service request originator, mainly in order to understand the signal of the current cell, to facilitate network optimization. 如果此时由于UE的移动需要进行切换,那么由源eNB发起定位业务请求所得到的UE的定位结果,对于源eNB而言没有任何意义,应该及时终止后续的定位过程。 At this time, if the location result of the UE due to movement of the UE needs to handover, then the location service initiated by the source eNB requests the obtained have no meaning to the source eNB, the positioning should be promptly terminate the subsequent process.

[0055] 本发明中,eNB发起定位业务请求的过程中,判定UE需要进行切换时,向增强型服务移动位置中心(E-SMLC,Enhanced Serving Mobile LocationCentre)发送包含终止定位请求的定位控制信令;E-SMLC收到包含终止定位请求的定位控制信令后,根据当前定位过程使用的定位方法,如果使用基于网络的定位方法,即UE不参与定位过程的定位信令交互,则指示eNB终止定位过程;如果使用基于UE的定位方法,即UE参与到定位测量、上报过程,则指示UE终止定位过程;如果当前定位方法未选定,则指示eNB终止定位过程即可。 [0055] In the present invention, the eNB initiates the process of positioning in the positioning service request, it is determined that the UE needs to handover to the enhanced service mobile location center (E-SMLC, Enhanced Serving Mobile LocationCentre) transmits a location request to terminate the control signaling ; the E-SMLC receives location request including the stop positioning control signaling, the method according to the current location using positioning process, if network-based positioning method, i.e., not involved in a signaling interaction UE positioning positioning process, indicating termination eNB positioning process; If UE-based positioning method, i.e. to participate UE positioning measurements, reporting procedure, the UE terminates the positioning process is indicated; if the current selected positioning method is not, it terminates positioning process to indicate eNB.

[0058] 步骤203 :由于eNB之前已经发起了对UE的定位,但还未收到定位响应,需请求终止此定位过程,通过定位协议LPPa (LPPa,LTE Positioning Protocol)向E-SMLC发送包含终止定位请求的定位控制信令。 [0058] Step 203: Since the eNB has initiated before the positioning of the UE, but not received in response to the positioning required for this positioning request to terminate the process, by positioning protocol LPPa (LPPa, LTE Positioning Protocol) to the E-SMLC transmits a termination positioning location request control signaling.

[0059] 包含终止定位请求的定位控制信令可以是基于LPPa新增加的一条定位控制信令,该定位控制信令包含终止定位请求的消息字段;也可以是利用LPPa的现有定位控制信令,在基于LPPa的现有定位控制信令中增加一个表示终止定位请求的消息字段。 [0059] A termination location request positioning control signaling may be based on a newly added LPPa positioning control signaling, the signaling message field positioning control comprising positioning request termination; may also be positioned using conventional control signaling LPPa increase in the conventional positioning control based LPPa signaling represents a terminating location request message field.

[0060] E-SMLC收到包含终止定位请求的定位控制信令后,根据当前定位过程使用的定位方法进行相应处理,如果使用基于网络的定位方法,即UE不参与定位过程的定位信令交互,则执行步骤204a,E-SMLC指示eNB终止定位过程;如果使用基于UE的定位方法,即UE 参与到定位测量、上报过程,则执行步骤204b,E-SMLC指示UE终止定位过程;如果当前定位方法未选定,执行步骤204a,E-SMLC指示eNB终止定位过程即可。 [0060] E-SMLC receives location request comprises positioning the terminating control signaling, processing corresponding positioning method according to the current position during use, if network-based positioning method, i.e., not involved in a signaling positioning UE positioning interaction perform step 204a, E-SMLC indicating eNB terminates positioning process; If positioning method UE based, i.e. UE involved in the positioning measurements, reporting procedure, step 204b, E-SMLC indicating the UE terminates positioning process; if the current location The method is not selected, step 204a, E-SMLC terminates positioning process to indicate eNB.

[0061 ] 步骤204a =E-SMLC使用LPPa指示eNB终止定位过程。 [0061] Step 204a = E-SMLC using LPPa eNB indicating the termination location process.

[0062] 基于LPPa指示eNB终止定位过程的具体实现:可以是基于LPPa新增加的一条定位控制信令,该定位控制信令包含终止定位过程的消息字段;也可以是利用基于LPPa的现有定位控制信令,在基于LPPa的现有定位控制信令中增加一个表示终止定位过程的消息字段。 [0062] eNB indicating termination embodied LPPa positioning process based on: LPPa may be based on a newly added control signaling positioning, the positioning control signaling message field comprising a positioning process terminates; may be based on existing positioning of LPPa control signaling, adding a terminating positioning process represents a message field based on the conventional positioning LPPa control signaling.

[0063] 步骤204b :或者,E-SMLC基于LPP指示UE终止定位过程。 [0063] Step 204b: Alternatively, E-SMLC terminates positioning process based on the indication LPP UE.

[0064] 基于LPP指示UE终止定位过程的具体实现:可以是基于LPP新增加的一条定位控制信令,该定位控制信令包含终止定位过程的消息字段;也可以是利用基于LPP的现有定位控制信令,在基于LPP的现有定位控制信令中增加一个表示终止定位过程的消息字段。 [0064] Depending on implementation indicate that the UE LPP terminating positioning process: LPP may be based on a newly added control signaling positioning, the positioning control signaling message field comprising a positioning process terminates; may be based on use of the existing positioning LPP control signaling, adding a terminating positioning process represents a message field based on the conventional LPP positioning control signaling.

[0065] 步骤205 :源eNB向目标eNB发送切换请求,进行UE的切换处理。 [0065] Step 205: The source eNB sends a handover request to the target eNB, a handover of the UE.

[0066] 步骤206 :源eNB或UE收到终止定位过程的指示后,停止定位相关的测量、上报过程,UE、eNB、E-SMLC释放定位相关资源,定位过程结束。 [0066] Step 206: After receiving the UE the source eNB indicating the termination or positioning process, stopping location-related measurements, reporting procedure, UE, eNB, E-SMLC positioning releases related resources, positioning the end of the process. [0067] 图3为本发明中eNB发起定位过程中UE发生切换时的具体实施例二流程图,如图3所示,具体处理过程包括: [0067] FIG. 3 embodiment when the eNB initiates handover of the UE occurs two positioning a flow chart shown in Figure 3 of the present invention, specifically the process comprises:

[0068] 步骤301〜步骤302 :eNB通过MME向E-SMLC发送定位业务请求,发起对UE的定位。 [0068] Step 301~ Step 302: eNB sends a location service request to the E-SMLC via MME, the UE initiates positioning. eNB收到定位响应前,UE上报测量报告,eNB、即源eNB判定UE需要进行切换。 ENB receives a response before positioning, measurement report UE, eNB, i.e., the source eNB determines that the UE needs to handover.
