Description

终止定位进程的方法与装置 技术领域
本发明涉及用户终端（UE, User Equipment )的定位技术， 尤其涉及一 种终止定位进程的方法与装置。 背景技术
图 1为蜂窝无线通讯系统的结构示意图， 如图 1所示， 蜂窝无线通讯 系统主要由核心网 （CN, Core Network ), 接入网 （RAN, Radio Access Network )和用户终端组成。 核心网负责非接入层事务， 例如对用户终端进 行位置更新等， 核心网是用户面的锚点。 接入网包括基站， 或者基站以及 基站控制器， 接入网负责接入层事务， 例如无线资源的管理等， 基站之间 可以根据实际情况存在物理或者逻辑上的连接，如图 1中的基站 1与基站 2 或基站 3之间的连接， 每个基站可以与一个以上的核心网节点连接。 用户 终端是指可以和蜂窝无线通讯网络通讯的各种设备， 比如移动电话或者笔 记本电脑等。
图 2为基于 IP的长期演进 ( LTE, Long Term Evolution )蜂窝无线通讯 系统的扁平化架构示意图， 如图 2所示， LTE蜂窝无线通讯系统由演进的 通用地面无线接入网（E-UTRAN, Evolved Universal Terrestrial Radio Access Network )和核心网节点组成。其中核心网节点包括：移动性管理实体（ MME, Mobility Management Entity ), 服务网关 （ S-GW, Serving Gateway )等。 MME负责移动性管理、 非接入层信令的处理、 用户的移动管理上下文的管 理等控制面相关工作； S-GW负责 UE用户面数据的传送、 转发和路由切换 等。 E-UTRAN包括基站（ eNB ), e B之间在逻辑上通过 X2接口互相连接， 用于支持 UE在整个网络内的移动性， 保证用户的无缝切换。 为了支持提供定位业务， 网络侧设置有网络实体服务移动定位中心
( SMLC, Serving Mobile Location Center ), 专用于对定位的管理和配置。 对 UE进行进行定位时，所有的定位请求通过 MME发送到 SMLC,由 SMLC 管理 eNB或 UE来执行定位操作， 如执行定位测量和结果上报等。
SMLC在接收到定位请求后， 选择 eNB或 UE进行定位， 将定位信息 请求和可能需要的定位辅助数据等发送给 eNB或 UE。 eNB和 UE接收到 SMLC发送的定位信息请求后， 根据定位信息请求中指示的内容进行定位 测量， 并根据要求周期性或事件触发性地上报测量结果， 或直接上报所计 算的位置信息。
然而当 eNB或 UE正在执行周期性上报时， 请求定位的主体， 例如演 进的分组核心网（ EPC, Evolved Packet Core )中的位置业务（ LCS, Location Service )实体认为已经获得足够的终端位置信息或者是不再需要该 UE的位 置信息， 或者觉得当前定位方法的精度不够， 需要调整更新定位方法， 而 且当前周期性上报未能达到最大报告数， 应该可以请求终止当前定位进程。 但目前的协议尚未涉及到主动终止对 UE的定位流程。 发明内容
有鉴于此， 本发明的主要目的在于提供一种终止定位进程的方法与装 置， 能提前终止用户终端定位测量， 避免用户终端作不必要的测量而导致 电量损耗。
为达到上述目的， 本发明的技术方案是这样实现的：
一种终止定位进程的方法， 包括：
服务移动定位中心 SMLC接收到终止对用户终端定位的请求后， 向执 行定位的网元发送终止定位进程指令。

优选地， 所述终止对用户终端定位的请求由所述用户终端、 当前为所 述用户终端服务的基站或移动性管理实体 MME发送给所述 SMLC。
优选地， 所述终止对用户终端定位的请求包括： 位置服务终止请求或 定位进程终止请求。
优选地， 所述终止定位进程指令为独立消息， 或承载于现有发送至所 述执行定位的网元的消息中通知给所述执行定位的网元； 所述位置服务终 止请求或定位进程终止请求为独立消息， 或承载于现有发送至所述 SMLC 的消息中通知给所述 SMLC。

优选地， 所述执行定位的网元包括所述用户终端或当前为所述用户终 端服务的基站。
本发明中， 当 UE或基站确定不必再进行定位服务时，将向网络侧发送 终止对 UE定位进程的请求，网络侧根据请求向当前执行定位的网元发送终 止定位进程指令，使当前执行定位的网元终止对 UE的定位进程。从而使本 发明支持提前终止 UE的定位测量，避免了 UE不必要的测量而导致的电量 损耗。 附图说明
