Description

一种小区选择方法及装置 技术领域
本发明涉及通信领域，特别涉及一种小区选择方法及装置。
背景技术
第三代合作伙伴项目(3rd Generation Partnership Project，3GPP)定义了用户设备(User Equipment，UE)在非接入层(Non-Access Stratum，NAS)需要维护等价网络(Equivalent Public Land Mobile Network,EPLMN)列表，禁止位置区域列表，禁止网络(Forbidden PLMN)列表和GPRS(General Packet Radio Service，通用分组无线业务)业务禁止网络(Forbidden PLMNs for GPRS service)列表等列表信息。
网络侧在附着接受消息或位置更新接受消息中将EPLMN列表下发给UE，UE对该EPLMN列表进行保存；对于所有的无线接入技术(Radio Access Technology，RAT)，UE任何时刻只保存最新从网络侧接收到的一个EPLMN列表。若网络侧因为UE所在位置区域不允许而拒绝了UE的注册请求，则UE将所在的当前位置区域加入到对应的禁止位置区域列表中。若网络侧因为网络不允许(PLMN not allowed)而拒绝了UE的注册请求，则UE将当前网络的身份标识加入到Forbidden PLMN列表中，若网络侧因为GPRS业务在网络不允许(GPRS services not allowed in this PLMN)或EPS(Evolved Packet System，演进分组系统)业务在网络不允许(EPS services not allowed in this PLMN)而拒绝了UE的注册请求，则UE将当前网络的身份标识加入到GPRS业务禁止网络(Forbidden PLMNs for GPRS service)列表中。
3GPP也定义了UE选择合适小区(suitable cell)的方法，合适小区是UE当前选择的PLMN的一个小区，或者是UE当前注册PLMN的一个小区，或者是UE的等价PLMN中的一个小区，同时，合适小区所在的位置区域不在禁止位置区域列表中。3GPP进一步定义了对于跨EPLMN的小区重选，NAS层是不需要执行PLMN选择流程的，AS(Access Stratum，接入层)层通过小区重选可以实现在EPLMN之间的无缝移动。
在合适小区的选择过程中，UE的NAS层会提供维护的EPLMN列表与禁止位置区域列表给UE的AS层。同时，在合适小区的选择过程中，NAS层会提供当前使用的RAT信息给AS层。UE的NAS层，可以配置不同的工作模式：只支持CS(Circuit Switched，电路交换)，只支持PS(Packet Switched，分组交换)，支持CS与PS。对于支持CS与PS的UE，进一步可以配置是CS优先还是PS优先。
UE因为通过底层的合适小区重选，可以驻留在一个EPLMN中的合适小区而无需发起网络选择流程，当这个EPLMN又包含在禁止网络列表或GPRS业务禁止网络列表中时，会导致UE进入服务受限态，即：能够正常驻留但不能获取正常的业务，从而影响了用户体验。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，下面所描述的实施例仅仅是本发明一部分实施例，而非全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应当理解，尽管在本发明实施例中可能采用术语第一、第二等来描述各个用户或终端，但用户或终端不应限于这些术语。这些术语仅用来将用户或终端彼此区分开。例如，在不脱离本发明实施例范围的情况下，第一用户也可以被称为第二用户，类似地，第二用户也可以被称为第一用户；同样的，第二用户也可以被称为第三用户等等，本发明实施例对此不做限制。
首先对本发明所要解决的技术问题、以及所涉及的网元和功能进行概述：
UE在保存EPLMN列表之前，需要检查对应的禁止网络列表，具体地：
对于PS域，UE在保存网络侧在附着接受消息或位置更新接受消息中下发的EPLMN列表之前，检查是否有EPLMN包含在禁止网络列表，或者GPRS业务禁止网络列表中，若有，则将包含在这两个禁止网络列表中的EPLMN从保存的EPLMN列表中删除，也即UE最后保存的EPLMN列表中，EPLMN不会包 含在禁止网络列表或GPRS业务禁止网络列表中。而对于CS域，不同于PS域，UE在保存网络侧在附着接受消息或位置更新接受消息中下发的EPLMN列表之前，只检查是否有EPLMN包含在禁止网络列表中，而不检查GPRS业务禁止网络列表。若有，则将包含在禁止网络列表中的EPLMN从保存的EPLMN列表中删除，也即在保存的EPLMN列表中，EPLMN可能也包含在GPRS业务禁止网络列表中。其中，CS域与PS域处理不一致的主要考虑是：CS域与PS在移动管理上是独立的，CS业务不受PS业务受限的影响。
对于同时支持CS与PS的UE，上述方案不能很好地兼顾CS业务与PS业务的可用性，例如，在如下场景下，会导致UE进入能够正常驻留但不能获取正常PS业务的状态：
假设UE的操作模式为支持CS业务与PS业务，PLMN A处于UE的GPRS业务禁止网络列表中。PLMN A,PLMN B,PLMN C均不在UE的禁止网络列表中；
UE在PLMN B因为RA(Routing Area，路由区)改变发起单独的RAU(Routing Area Update，路由区更新)，SGSN(Serving GPRS Support Node，服务GPRS支持节点)在RAU accept消息中携带了EPLMN列表：{PLMN A,PLMN C}；
UE在接收RAU accept消息后，将PLMN A从EPLMN列表中删除，故保存的EPLMN列表为：{PLMN B,PLMN C}；
UE因为满足LAU(Location Area Update，位置区域更新)的触发条件(比如周期性LAU)发起了单独的LAU，MSC(Mobile Switching Centre，移动交换中心)在LAU accept消息中也携带了EPLMN列表：{PLMN A,PLMN C}；
UE在接收LAU accept消息后，不会将PLMN A从EPLMN列表中删除，故保存的EPLMN列表为：{PLMN A,PLMN B,PLMN C}；
UE的AS层(Access Stratum，接入层)进行小区重选进入PLMN A，从而进入能够正常驻留但不能获取正常PS业务的状态，影响用户体验。
本发明所涉及的网元及功能如下：
UE NAS(用户设备的非接入层)：
(1)维护EPLMN列表，禁止位置区域列表，禁止网络列表和GPRS业务禁止网络列表等列表信息；
(2)执行PLMN选择；
(3)为UE AS层执行小区选择提供EPLMN列表，禁止位置区域列表，RAT等信息；
(4)执行注册等移动性管理功能。
UE AS(用户设备的接入层)：
(1)根据NAS层提供的信息进行合适小区的选择；
(2)在合适小区进行正常驻留。

可以理解的是，该禁止网络列表中包含的网络是对于该UE的GPRS业务 与非GPRS业务均不可用的网络，该GPRS业务禁止网络列表中包含的网络是对于该UE的GPRS业务不可用的网络，该非GPRS业务禁止网络列表中包含的网络是对于该UE的非GPRS业务不可用的网络。
