Description

终端的位置管理方法、寻呼方法、装置和终端
本申请要求于2015年05月25日提交中国专利局，申请号为201510272312.2、发明名称为“终端的位置管理方法、寻呼方法、装置和终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，具体而言，涉及一种处于网络覆盖外的终端的位置管理方法、一种处于网络覆盖外的终端的位置管理装置、一种对处于网络覆盖外的终端进行寻呼的方法、一种对处于网络覆盖外的终端进行寻呼的装置和一种终端。
背景技术
3GPP Release 12开始已经引入了部分覆盖场景的讨论，即进行D2D(Device-to-Device，设备对设备)通信的两个或者多个终端，有的位于网络覆盖内，有的位于网络覆盖外。位于网络覆盖范围内的终端，可以由网络侧实现对其的位置管理，而位于网络覆盖外的终端，3GPP尚未定义如何进行位置管理。如图1所示为部分覆盖场景示意图，在部分覆盖场景示意图中，基站通过S1接口与SAE(System Architecture Evolution，系统架构演进)或核心网(Core Network)建立连接，中继UE(User Equipment，用户设备)可以与基站建立RRC(Radio Resource Control，无线资源控制)和NAS(Non-access Stratum，非接入层)信令连接，远端UE可与中继UE进行D2D通信。
由于现有技术的位置管理主要依靠UE与网络侧的控制信令连接，如NAS连接，而在部分覆盖场景下，远端UE与网络侧的NAS连接可能并不存在，因此现有技术并不支持对覆盖外终端的位置管理。然而，在特定的场景下，网络侧仍然是需要知道远端UE是否存在，或者需要通过寻呼来触发远端UE发起D2D通信，如启动中继UE的选择和连接过程等，而现有方案却导致远端UE的位置信息无法进行管理。如果网络侧需要通过中继UE来寻呼远端UE，缺乏位置管理信息的结果是网络需要在全网进行寻呼消息的广播，随着终端数 量的不断增加，这无疑会造成极大的无线资源浪费。
因此，如何能够实现对处于网络覆盖外的终端的位置信息进行管理，避免了在需要寻呼远端UE时在全网广播寻呼消息而导致占用较多的无线资源成为亟待解决的技术问题。
发明内容
本发明正是基于上述技术问题至少之一，提出了一种新的处于网络覆盖外的终端的位置管理方案和寻呼方案，能够实现对处于网络覆盖外的终端的位置信息进行管理，进而能够实现在指定范围内对远端UE进行寻呼操作，避免了在需要寻呼远端UE时在全网广播寻呼消息而导致占用较多的无线资源。
有鉴于此，根据本发明的第一方面，提出了一种处于网络覆盖外的终端的位置管理方法，所述终端可与中继终端进行D2D通信，所述中继终端处于网络的覆盖范围之内，所述终端的位置管理方法，包括：所述终端获取进行位置管理的粒度信息，所述粒度信息用于标识所述终端所处的位置；所述终端根据所述粒度信息和是否获取到所述中继终端的标识信息，向网络侧服务器上报所述终端的位置信息，以供所述网络侧服务器对所述终端的位置进行管理。
在该技术方案中，由于处于网络覆盖外的终端(以下简称为远端UE)能够与中继终端进行D2D通信，因此可以根据中继终端的位置间接确定远端UE的位置；同时，根据进行位置管理的粒度信息(如小区级别或宏小区簇级别)和是否获取到中继终端的标识信息能够确定中继终端所处的位置信息，而中继终端所处的位置信息对应于远端UE的位置信息，因此可以根据上述粒度信息和是否获取到中继终端的标识信息，来向网络侧服务器上报远端UE的位置信息，进而使得网络侧服务器能够实现对处于网络覆盖外的远端UE的位置信息进行管理，避免了在需要寻呼远端UE时在全网广播寻呼消息而导致占用较多的无线资源。其中，中继终端的标识信息可以是SAE标识。上述的粒度信息具体是用于标识远端UE所处位置的等级，如标识远端UE所处位置为小区等级、跟踪区等级或是宏小区簇等级等。此外，远端UE在向网络侧服务器上报终端的位置信息时，可以触发中继终端向网络侧服务器进行上报，或通过远端UE与网络侧服务器之间的PC3接口进行上报。

在该技术方案中，若未获取到中继终端的标识信息，则可以根据中继终端从网络侧设备转发的E-CGI信息来确定远端UE的位置信息，由于E-CGI信息是小区级别的，因此若进行位置管理的粒度信息是小区等级的，则可以直接将E-CGI信息上报至网络侧服务器，若进行位置管理的粒度信息是宏小区簇级别的，则可以将E-CGI信息所属的宏小区簇的标识信息上报至网络侧服务器，以供网络侧服务器确定远端UE的位置信息。同样地，远端UE在向网络侧服务器上报终端的位置信息时，可以触发中继终端向网络侧服务器进行上 报，或通过远端UE与网络侧服务器之间的PC3接口进行上报。
在上述技术方案中，优选地，所述终端获取进行位置管理的粒度信息的步骤具体包括：所述终端获取预存储在所述终端内或预存储在所述终端的通用集成电路卡(Universal Integrated Circuit Card，UICC)中的所述粒度信息；或

在该技术方案中，若未获取到中继终端的标识信息，则可以根据中继终端从网络侧设备转发的E-CGI信息来确定远端UE的位置信息，由于E-CGI信息是小区级别的，因此若进行位置管理的粒度信息是小区等级的，则可以直接将E-CGI信息上报至网络侧服务器，若进行位置管理的粒度信息是宏小区簇级别的，则可以将E-CGI信息所属的宏小区簇的标识信息上报至网络侧服务器，以供网络侧服务器确定远端UE的位置信息。同样地，远端UE在向网络侧服务器上报终端的位置信息时，可以触发中继终端向网络侧服务器进行上报，或通过远端UE与网络侧服务器之间的PC3接口进行上报。

在上述技术方案中，优选地，所述发送单元502具体用于：通过其他实体设备的中转，以向所述网络侧服务器发送对所述终端的位置信息的获取请求；或定义新的接口，以通过所述接口向所述网络侧服务器发送对所述终端的位置信息的获取请求。
以下结合图6详细说明本发明的技术方案。
图6示出了根据本发明的实施例的对处于网络覆盖范围外的终端进行位置管理和寻呼的方法的示意流程图。
如图6所示，首先，网络侧服务器(如ProSe Application Server或者ProSe Function)和远端UE需要就是否需要位置管理以及实现位置管理的粒度进行配置。
其中，这个配置过程可以是预配置在远端UE中或者UICC中的，也可以是在远端UE位于网络覆盖内时通过与网络侧服务器的连接来动态配置。其中，位置管理的粒度可以是小区级，跟踪区域TA(tracking area)级，也可以是为D2D业务支撑而引入的多个宏小区簇级别的。
宏小区簇级别可以由网络运营商进行划分和配置，其划分需要配置在终端中。划分宏小区簇进行远端UE的位置管理，能够突破TA的局限，使得远端UE的位置管理更加灵活。比如：宏小区簇的划分依据可以是与D2D业务的资源配置相关联的，这样能够实现UE的D2D资源配置变更与位置更新的同步发生，可以减少远端UE与网络侧服务器的交互次数。
其次，远端UE依据所配置的位置更新粒度，进行有条件的位置更新，基本原则如下：
若远端UE与中继UE具有正在进行的D2D通信且远端UE具有中继UE的标识信息(如SAE标识信息)，则远端UE可以触发中继UE将位置信息报 告给ProSe Function；
若远端UE没有获取到中继UE的标识信息或者远端UE只是处于中继UE的中继范围内而并没有正在进行的D2D通信，则远端UE检测中继UE从网络侧转发的E-CGI信息，与自身所配置的粒度进行比对：如果位置管理的粒度是小区级的，则远端UE将位置信息(即当前的E-CGI)汇报给网络侧服务器(如ProSe Function)；如果位置管理的粒度是宏小区簇级别的，则远端终端确定该E-CGI所属的宏小区簇，进而将该E-CGI所属的宏小区簇的标识信息汇报给网络侧服务器。
其中，在远端UE向网络侧服务器汇报位置时，可以使用新的标识将位置信息汇报给ProSe Function。需要注意的是，本发明提出的位置管理与传统基于MME的位置管理机制不同，位置信息的维护实体是ProSe Function；远端UE汇报给ProSe Function的标识，并不需要像S-TMSI(SAE Temporary Mobile Subscriber Identifier，SAE中UE的临时移动用户标识，用于标识移动终端)那样完全由MME这样的控制实体来分配，远端UE汇报给ProSe Function的标识可以是UE与ProSe Function通过PC3接口协商分配好的；ProSe Function需要具备映射能力，使得远端UE上报的标识能够与3GPP SAE的标识如S-TMSI进行映射。
再次，基于如上的位置管理机制，本发明可以实现高效率的寻呼机制：网络侧在寻呼UE时，MME首先需要从ProSe Function处获取UE的位置信息，即位置查询，ProSe Function进行位置反馈后，MME根据中继UE的标识、宏小区或者宏小区簇的信息决定是否发起寻呼以及是否可以在特定小区范围的寻呼，以避免全网广播式的寻呼。
具体地，若ProSe Function查到了远端UE当前正在进行通信的中继UE的标识，则可以直接根据中继UE的位置信息来确定远端UE的位置信息；由于现有网络架构没有定义MME与ProSe Function之间直接的接口，因此，MME向ProSe Function发起位置查询消息需要通过其他实体中转，或者直接定义新的接口来实现。
本发明上述实施例中的技术方案可以实现对处于网络覆盖外的远端UE进行一定频率一定位置粒度的位置管理，解决部分覆盖场景下网络侧在寻呼远端 UE时的盲目寻呼发送问题。
