Description

一种区域变化类位置信息请求中通知 /验证的处理方法 技术领域
本发明涉及网络设备的定位技术， 特别是指一种区域变化类位置信 息请求中通知 /验证的处理方法。 发明背景
移动通信网络的位置业务（LCS, Location Service )是通过定位技 术得到目标用户设备（UE )的位置信息， 目标 UE是指移动通信网络中 被定位的设备终端， 位置信息可以是地理的经纬度信息或当地街道的位 置信息。 移动通信网络获取的位置信息可以提供给目标 UE, 用于目标 UE 的自身定位； 也可以提供给通信网络本身， 用于分区域计费或操作 维护； 也可以提供给其他请求得到目标 UE位置信息的客户应用端， 如 机构和个人， 用于增值业务。 因此， 位置业务在紧急救援、 车辆导航和 智能交通系统、 工作调度和团队管理、 移动黄页查询、 增强网络性能等 方面均有广泛的作用。 在第三代合作伙伴计划 （3GPP ) 中对 LCS规范 以及整个实现位置业务的功能模式、 结构、 状态描述和消息流程等方面 均作了描述。
图 1为实现位置业务的逻辑结构示意图，如图 1所示，请求端（LCS Client )101通过包含 LCS系统的网络 102请求目标 UE 103的位置信息， 包含 LCS系统的网络 102对 LCS Client 101进行合法性鉴权， 验证目标 UE 103是否允许向该 LCS Client 101提供其位置信息， 如果 LCS Client 101通过包含 LCS系统的网络 102的合法性鉴权，则包含 LCS系统的网 络 102接受 LCS Client 101对目标 UE 103发起的位置信息请求，对目标 UE 103进行定位， 并向该 LCS Client 101提供对目标 UE 103的定位结 果； 否则， 包含 LCS系统的网络 102拒绝 LCS Client 101对目标 UE 103 发起的位置信息请求。
LCS系统中能够实现位置业务的功能逻辑实体包括网关移动定位中 心（GMLC )、 用户数据存储服务器（HLR/HSS )、 核心网络（ CN )和无 线接入网络 （RAN )。 GMLC 可进一步包括请求网关移动定位中心 ( R-GMLC, Requesting GMLC ), 归属网关移动定位中心 （H-GMLC, Home GMLC )和拜访网关移动定位中心 （ V-GMLC, Visited GMLC )。 R-GMLC是指接收 LCS Client向目标 UE发起的位置信息请求的 GMLC, H-GMLC是指目标 UE所归属的 GMLC, V-GMLC是指当前为目标 UE 服务的 GMLC, 即目标 UE当前所在的 GMLC。 R-GMLC、 H-GMLC和 V-GMLC 可以为同一个物理实体， 也可为不同物理实体。 HLR/HSS 用 于存储用户数据， 并为其他网络逻辑实体提供 UE 的相关信息， 如 UE 的 H-GMLC、 V-GMLC和 CN的地址信息。 CN接收并管理 GMLC对目 标 UE发起的位置信息请求，协同 RAN对目标 UE进行定位，并向 GMLC 发送定位结果。 RAN在 CN的请求下对目标 UE进行定位， 并向 CN返 回对目标 UE的定位结果。
目前， 3GPP规范中定义了区域变化类位置信息请求及其处理流程。 区域变化类位置信息请求是指 LCS Client预先指定目标区域范围和触发 位置报告的事件， 例如目标 UE进入、 离开或是位于指定目标区域范围 时向 LCS Client上报位置区域事件报告， LCS系统将指定目标区域范围 和触发位置报告事件等信息发送至目标 UE，目标 UE存储指定目标区域 范围和触发位置报告事件等信息， 同时启动相应的应用程序， 当应用程 序监测到触发位置报告事件发生时， 例如目标 UE进入、 离开或是位于 指定目标区域范围， 目标 UE向 LCS系统上报位置区域事件报告， LCS 系统向相应的 LCS Client转发该位置区域事件报告，通知相应 LCS Client 其指定的触发位置报告事件已发生。 LCS Client还可指定目标 UE向其 上报位置区域事件报告的次数， 例如， 仅上报一次位置区域事件报告， 或在指定的有效时间范围内进行周期性上报。 综上所述， 利用区域变化 类位置信息请求， LCS Client可方便灵活地定义一些跟踪监控类位置业 务， 例如， 儿童跟踪、 宠物跟踪等， 使得位置业务能够在跟踪监控方面 得到更广泛的应用。
另外， 3GPP规范对区域变化类位置信息请求的处理流程进行了增 强， LCS Client不仅能够要求目标 UE在触发位置报告事件发生时， 通 过 LCS系统向其上报位置区域事件报告； 还可以要求 LCS系统在返回 位置区域事件报告的同时， 提供目标 UE的当前位置信息。 因此， LCS 系统在收到目标 UE上报的位置区域事件报告后， 会判断 LCS Client是 否要求向其提供目标 UE的当前位置信息， 如果是， 则 LCS系统对目标 UE进行定位，然后向 LCS Client返回位置区域事件报告和目标 UE的当. 前定位结果； 否则， LCS系统仅向 LCS Client返回位置区域事件报告。
图 2为现有技术中 LCS Client请求目标 UE位置信息的区域变化 类位置信息请求处理流程图， 如图 2所示， LCS Client请求目标 UE 位置信息的区域变化类位置信息请求的处理过程包括以下步骤：
步骤 201 : LCS Client向 R-GMLC发送 LCS业务请求（ LCS Service Request ) , 该 LCS Service Request中携带有目标 UE标识、 指定目标 区域范围和触发位置报告事件，触发位置报告事件可为目标 UE进入、 离开或是位于指定目标区域范围时上报位置区域事件报告； 该 LCS Service Request中还携带有定位指示，该定位指示用于通知 LCS系统 在目标 UE上报位置区域事件报告时， 对目标 UE进行精确定位， 并 且该 LCS Service Request中可进一步携带有服务质量 ( QoS )信息， 指示 LCS 系统对目标 UE进行精确定位获取的位置信息应满足 QoS 信息。 LCS Service Request中还可携带有区域变化类位置信息请求的 有效时间范围， 如起始时间和终止时间， 以及区域变化类位置信息请 求要求目标 UE上报位置区域事件报告的次数， 如果需要多次上报位 置区域事件报告，则该 LCS Service Request中还需携带有周期性上报 位置区域事件报告的时间间隔。
步骤 202: R-GMLC收到 LCS Service Request后， 存储 LCS Service Request 中携带的定位指示， 并为当前区域变化类位置信息请求分配序 列号 （ Reference Number )， 然后向 H-GMLC转发 LCS Service Request, 该转发的 LCS Service Request 中进一步携带有 Reference Number。
H-GMLC收到 LCS Service Request后， 对 LCS Client进行合法性鉴权， 确定目标 UE是否允许 LCS系统向该 LCS Client提供其位置信息或位置 区域事件报告， 如果该 LCS Client通过合法性鉴权， 则 H-GMLC 向 V-GMLC转发 LCS Service Request, 该转发的 LCS Service Request中可 进一步携带有 Notification/Verification指示， Notification/Verification指示 用于通知目标 UE对 LCS Client进行私密性验证； 否则， H-GMLC向 R-GMLC返回鉴权失败消息， R-GMLC拒绝该 LCS Client对目标 UE发 起的区域变化类位置信息请求， 结束当前区域变化类位置信息请求的处 理流程。
使用目标 UE 的用户在签约私密性信息时， 可要求 LCS 系统在有 LCS Client对目标 UE发起位置信息请求时发送通知信息或是发送验证 请求。 当签约了发送通知信息时， 在有 LCS Client对其发起位置信息请 求时， LCS系统将 LCS Client发起的位置信息请求中携带的相关信息， 如 LCS Client标识、 LCS Client提供的验证字 （ cordword )等信息发送 给目标 UE,通知目标 UE该 LCS Client正请求其位置信息， 当签约了发 送验证请求时，则 LCS系统请求使用该目标 UE的用户对 LCS Client提 · 供的信息进行验证， 使用目标 UE的用户可以接受或是拒绝当前位置信 息请求，并通过目标 UE向 LCS系统提供相应的接受或是拒绝指示， LCS 系统根据收到的指示， 确定是否继续后续的定位流程， 或是拒绝 LCS Client对目标 UE发起的定位请求。
步骤 203: V-GMLC收到 LCS Service Request后， 将该 LCS Service
Request 中携带的指定目标区域范围转换为网络能够识别的地域标识， 并向 CN发送定位目标 UE请求（ Provide Subscriber Location ),该 Provide Subscriber Location中携带目标 UE标识、转换后的以网络地理格式表示 的指定目标区域范围和触发位置报告事件； 与 LCS Service Request中携 带的信息相对应， 该 Provide Subscriber Location中还可携带有上报位置 区域事件报告的次数， 如果需要多次上报位置区域事件报告， 则携带周 期性上报位置区域事件报告的时间间隔； 该 Provide Subscriber Location 中还携带有 Notification/Verification指示。
步骤 204: CN检测到目标 UE处于空闲模式， 该 CN对目标 UE 发起寻呼， 并对目标 UE进行鉴权和加密， 确定目标 UE是否为合法 的网络用户设备， 如果目标 UE为合法的网络用户设备， 则继续执行 步骤 205; 否则， 结束当前区域变化类位置信息请求的处理流程。
步骤 205 : CN根据 Provide Subscriber Location 中携带的通知 ( Notification ) /验证 （ Verification ) 指示， 向 目 标 UE 发送 Notification/Verification指示，当为 Notification指示时，该 Notification 指示中携带有 LCS Client标识、 位置信息请求类型， 通知目标 UE该 LCS Client请求其位置信息； 当为 Verification指示时,该 Verification 指示中携带有 LCS Client标识、 位置信息请求类型、 LCS Client验证 字等信息， 由目标 UE亲自对 LCS Client进行验证， 如果目标 UE允 许 LCS Client对其发起位置信息请求， 则目标 UE向 CN返回确认响 应， 通知 LCS系统可以向 LCS Client提供其位置信息， 然后继续执 行步骤 206， 否则， 目标 UE向 CN返回否定响应， 通知 LCS系统拒 绝 LCS Client向其发起的位置信息请求， CN向 V-GMLC返回失败的 定位目标 UE响应 （ Provide Subscriber Location Ack ) , V-GMLC向 H-GMLC 返回失败的 LCS 业务响应 （LCS Service Response ) , H-GMLC 向 R-GMLC 返回失败的 LCS Service Response , 最终， R-GMLC向 LCS Client返回失败的 LCS Service Response, 结束当前 区域变化类位置信息请求的处理流程。
步骤 206〜步骤 207: CN经由 RAN向目标 UE发送位置区域事件调 用请求 ( Location Area Event Invoke ), 该 Location Area Event Invoke中 携带的信息与 LCS Service Request中携带的信息相对应。 目标 UE收到 Location Area Event Invoke后， 存储指定目标区域范围和触发位置 4艮告 事件以及 R-GMLC 为当前区域变化类位置信息请求分配的 Reference Number, 如果需要多次上报位置区域事件报告， 则目标 UE还需存储周 期性上报位置区域事件报告的间隔时间， 然后 UE启动自身的相关应用 程序， 监测触发位置报告事件的发生。 目标 UE向 CN发送位置区域事 件调用响应 （ Location Area Event Invoke Ack ), 通 口 CN当前区 i或变 类位置信息请求已被接受、 并已进行相应处理。
步骤 208〜步骤 21 1 : CN收到 Location Area Event Invoke Ack后， 向 V-GMLC发送 Provide Subscriber Location Ack, 通知 V-GMLC当 前区域变化类位置信息请求已被目标 UE接受。 V-GMLC收到 Provide Subscriber Location Ack后， 向 H-GMLC发送 LCS Service Response, 通知 H-GMLC 当前区域变化类位置信息请求已被目标 UE 接受。 H-GMLC收到 LCS Service Response后 ,向 R-GMLC发送 LCS Service Response , 通知 R-GMLC当前区域变化类位置信息请求已被目标 UE 接受。 R-GMLC收到 LCS Service Response后， 向 LCS Client发送 LCS Service Response, 通知 LCS Client当前区域变化类位置信息请 求已被目标 UE接受。
步骤 212〜步骤 213: 触发位置区域事件发生， 即目标 UE进入、 离 开或是位于指定目标区域范围， 目标 UE经由 RAN向 CN发送位置区域 事件艮告 ( Location Area Event Report )， 该 Location Area Event Report 中携带有触发位置区域事件的类型及 R-GMLC 为当前区域变化类位置 信息请求分配的 Reference Number,通知 CN触发位置区域事件已发生。
步骤 214〜步骤 215: CN收到 Location Area Event Report后， 向 V-GMLC 发送目标 UE位置报告 （Subscriber Location Report ), 通知 V-GMLC目标 UE的触发位置区域事件已发生。 V-GMLC收到 Subscriber Location Report后，向 CN发送目标 UE位置才艮告响应（ Subscriber Location Report Ack ), 通知 CN已经收到其发送的 Subscriber Location Report, 此 时， CN可为当前区域变化类位置信息请求生成相应的话单记录。
步骤 216： V-GMLC向 CN发送 Subscriber Location Report Ack后， 向 H-GMLC发送 LCS Service Response, 通知 H-GMLC目标 UE的触发 位置区域事件已发生。
步骤 217: H-GMLC收到 LCS Service Response后， 可再次对 LCS Client进行合法性鉴权， 确保向 LCS Client提供位置区域事件报告属于 该 LCS Client的权限允许范围， 如果该 LCS Client通过合法性鉴权， 则 继续执行步骤 218; 否则， H-GMLC向 R-GMLC返回鉴权失败消息， R-GMLC拒绝该 LCS Client对目标 UE发起的区域变化类位置信息请求， 结束当前区域变化类位置信息请求的处理流程。
步骤 218: H-GMLC向 R-GMLC发送 LCS Service Response, 通知 R-GMLC 目标 UE 的触发位置区域事件已发生。 R-GMLC 收到 LCS Service Response后，判断 LCS Client是否要求提供目标 UE的当前位置 信息，即判断是否存储有对应于 Reference Number的定位指示，如果是， 则继续执行步骤 219 ; 否则， 直接向 LCS Client 发送 LCS Service Response, 通知 LCS Client目标 UE的触发位置区域事件已发生。
步骤 219: R-GMLC根据存储的对应于 Reference Number的定位指 示， 生成新的 LCS Service Request并向 H-GMLC发送， 该 LCS Service Request中携带有 LCS Client标识、步骤 201中的 QoS信息以及 R-GMLC 在步骤 202中分配的 Reference Number,
步骤 220〜步骤 221 : H-GMLC收到 LCS Service Request后， 对 LCS Client进行合法性鉴权，确定目标 UE是否允许 LCS系统向该 LCS Client 提供目标 UE的位置信息，如果该 LCS Client通过合法性鉴权， H-GMLC 根据目标 UE的私密性签约信息，向 V-GMLC转发 LCS Service Request, 该转发的 LCS Service Request中进一步携带有 Notification/Verification 指示； 否则， H-GMLC向 R-GMLC返回鉴权失败消息， R-GMLC拒绝 该 LCS Client对目标 UE发起的区域变化类位置信息请求， 结束当前区 域变化类位置信息请求的处理流程。
步骤 222: V-GMLC收到 LCS Service Request后，向 CN发送 Provide Subscriber Location , 该 Provide Subscriber Location中携带的内容与上面 所述的 LCS Service Request中携带的内容相对应。
步骤 223： CN 根据 Provide Subscriber Location 中携带的
Notification/Verification指示，向目标 UE发送 Notification/Verification指 示， 当为 Notification指示时， 该 Notification指示中携带有 LCS Client 标识、 位置信息请求的类型， 通知目标 UE该 LCS Client请求其位置信 息； 当为 Verification指示时， 该 Verification指示中携带有 LCS Client 标识、 位置信息请求的类型、 LCS Client验证字等信息， 由目标 UE亲 自对 LCS Client进行验证，如果目标 UE允许 LCS Client对其进行定位， 则目标 UE向 CN返回确认响应 , 通知 LCS系统可以向 LCS Client提供 其位置信息， 然后继续执行步骤 224, 否则， 目标 UE向 CN返回否定 响应， 通知 LCS系统拒绝 LCS Client向其发起的位置信息请求， CN向 V-GMLC 返回失败的 Provide Subscriber Location Ack, V-GMLC 向 H-GMLC返回失败的 LCS Service Response, H-GMLC向 R-GMLC返回 失败的 LCS Service Response, 最终， R-GMLC向 LCS Client返回失败 的 LCS Service Response, 结束当前区域变化类位置信息请求的处理流 程。
步骤 224〜步骤 226: CN向 RAN发送定位请求（ Location Request ), 该 Location Request中携带有 QoS信息， 请求 RAN根据 QoS信息对目 标 UE进行定位。 RAN收到 Location Request后， 根据 QoS信息对目标 UE进行定位操作。 定位结束后， RAN向 CN返回定位响应 （Location Response ), 该 Location Response中携带有目标 UE的定位结果。
步骤 227〜步骤 228: CN收到 Location Response后， 向 V-GMLC发 送携带有目标 UE定位结果的 Provide Subscriber Location Ack; V-GMLC 收到 Provide Subscriber Location Ack后， 向 H-GMLC发送携带有目标 UE定位结果的 LCS Service Response 0
步骤 229: H-GMLC收到 LCS Service Response后， 可再次对 LCS Client进行合法性鉴权， 确保向 LCS Client提供目标 UE的定位结果属 于该 LCS Client的权限允许范围， 如果该 LCS Client通过合法性鉴权， 则继续执行步骤 230; 否则， H-GMLC向 R-GMLC返回鉴权失败消息， R-GMLC拒绝该 LCS Client对目标 UE发起的区域变化类位置信息请求， 结束当前区域变化类位置信息请求的处理流程。
步骤 230〜步骤 231 : H-GMLC向 R-GMLC发送携带有目标 UE定位 结果的 LCS Service Response; R-GMLC收到 LCS Service Response后， 向 LCS Client发送携带有目标 UE定位结果的 LCS Service Response, 如果区域变化类位置信息请求中携带了周期性上报位置区域事件报 告的间隔时间和上报位置区域事件报告的次数， 则目标 UE向 CN上报 位置区域事件报告的时间间隔不能小于区域变化类位置信息请求中规 定的上报位置区域事件报告间隔时间 , 上报位置区域事件报告的总次数 不能超过区域变化类位置信息请求中要求的次数， 其每次上报位置区域 事件报告的处理过程与上述过程中步骤 212〜步骤 231基本相同。
由上述 3GPP规范定义的 LCS Client请求目标 UE位置信息的区域 变化类位置信息请求处理流程可见， 上述处理过程被拆分为位置区域事 件才艮告通知流程和定位目标 UE 流程两部分， 这两部分的处理流程中 LCS 系统均会 #居目标 UE的私密性签约信息， 通知目标 UE有 LCS Client请求其位置信息， 或是请求目标 UE对 LCS Client进行验证， 分 别在所述的步骤 205和步骤 223中实现。由此可见，对于同一 LCS Client 请求目标 UE位置信息的区域变化类位置信息请求， 却出现了两个独立 的目标 UE对 LCS Client进行验证的过程， 这样， 必然会导致使用目标 UE的用户产生误解， 无法确定两次通知 /验证之间的关系， 导致用户在 使用位置业务过程中的困惑； 并且由于目标 UE对 LCS Client进行验证 的过程是重复的， 毫无意义地增加了目标 UE的处理工作， 而且干扰了 目标 UE正在进行的其他处理流程。 发明内容
有鉴于此， 本发明的目的在于提供一种区域变化类位置信息请求中 通知 /验证的处理方法， 在区域变化类位置信息请求处理过程中， LCS Client请求目标 UE位置信息时，使得目标 UE对 LCS Client进行的通知 /验证更为合理。

为使本发明的目的、 技术方案和优点更加清楚， 下面结合附图对本 发明作进一步的详细描述。
本发明中， 在对 LCS Client请求目标 UE位置信息的区域变化类位 置信息请求进行处理时， LCS系统根据目标 UE的私密性签约信息， 仅 请求目标 UE对 LCS Client进行一次通知或验证， 避免使用目标 UE的 用户产生误解， 不会干扰目标 UE正在进行的其他处理流程。
本发明的一种实现方式是： 在 H-GMLC 中配置向目标 UE 发送 Notification/Verification指示的时间点， 如果在 H-GMLC 中配置在位置 区域事件报告阶段， 向目标 UE发送 Notification/Verification指示， 则在 而在后续的对目标 UE 进行定位阶段， 不再向目标 UE 发送 Notification/Verification指示；如果在 H-GMLC中配置在对目标 UE进行 定位阶段， 向目标 UE发送 Notification/Verification指示， 则在先前的位 置区域事件报告阶段中， 无需向目标 UE发送 Notification/Verification指 示， 而是在对 目 标 UE 进行定位阶段， 向 目 标 UE 发送 Notification/Verification指示。这样，可以根据运营商的指示，在 H-GMLC 中 配置 "在位置 区域事件报告阶段， 向 目 标 UE 发送 Notification/Verification指示" 或是配置 "在对目标 UE进行定位阶段， 向目标 UE发送 Notification/Verification指示"， 解决了同一区域变化类 位置信息请求流程中， LCS系统重复向用户发送通知 /验证消息的问题， 并可以提供两种向用户发送通知 /验证消息的时间点，满足运营商的不同 需求。
当 H-GMLC中配置为 "在位置区域事件报告阶段， 向目标 UE发送 Notification/Verification 指示" 时， 具体的处理流程是： H-GMLC 收到 R-GMLC发送的 LCS Service Request时，根据 LCS Service Request中的 信息， 如 H-GMLC判断 LCS Service Request中的 Reference Number为 是否为新分配的 Reference Number, 如果是， 则 H-GMLC确定出当前阶 段为区域变化类位置信息请求中的位置区域事件报告阶段， 否则， H-GMLC确定出当前阶段为区域变化类位置信息请求中的对目标 UE进 行定位阶段； 又如， H-GMLC判断 LCS Service Request中是否携带有 QoS信息， 如果没有携带， 则 H-GMLC确定出当前阶段为区域变化类 位置信息请求中位置区域事件报告阶段， 否则， H-GMLC确定出当前阶 段为区域变化类位置信息请求中对目标 UE 进行定位的阶段。 当 H-GMLC 确定出当前阶段为区域变化类位置信息请求中的位置区域事 件报告阶段时，根据 H-GMLC中配置的 "在位置区域事件报告阶段， 向 目标 UE发送 Notification/Verification指示"， H-GMLC按照正常流程进 行处理，直至执行完位置区域事件报告阶段； 当 H-GMLC确定出当前阶 段为区域变化类位置信息请求中对目标 UE 进行定位的阶段时， 根据 H-GMLC 中配置的 "在位置区域事件报告阶段， 向目标 UE 发送 Notification/Verification指示"， 在 H-GMLC对 LCS Client进行合法性鉴 权的过程中， 即使目标 UE 的签约信息设置为需要 LCS 系统发送 Notification/Verification 指示，■ H-GMLC 仍然根据配置信息， 在向 V-GMLC发送的 LCS Service Request中并不携带 Notification/Verification 指示。 因此， 后续 V-GML (：、 CN在对目标 UE进行定位的阶段， 不会 向目标 UE发送 Notification/Verification指示。
另外， H-GMLC中也可配置为 "在对目标 UE进行定位的阶段， 向 目标 UE发送 Notification Verification指示"， 其具体的处理流程同上类 似： H-GMLC收到 R-GMLC发送的 LCS Service Request时， 根据 LCS Service Request中的信息， 如 H-GMLC判断 LCS Service Request中的 Reference Number 为是否为新分配的 Reference Number, 如果是， 贝1 J H-GMLC 确定出当前阶段为区域变化类位置信息请求中位置区域事件 报告阶段， 否则， H-GMLC确定出当前阶段为区域变化类位置信息请求 中对目标 UE进行定位的阶段；又如， H-GMLC判断 LCS Service Request 中是否携带有 QoS信息， 如果没有携带， 则 H-GMLC确定出当前阶段 为区域变化类位置信息请求中位置区域事件报告阶段， 否则， H-GMLC 确定出当前阶段为区域变化类位置信息请求中对目标 UE进行定位的阶 段。 当 H-GMLC 确定出当前阶段为区域变化类位置信息请求中对目标 UE进行定位的阶段时， 根据 H-GMLC中配置的 "在对目标 UE进行定 位的阶段， 向目标 UE发送 Notification/Verification指示"， H-GMLC按 照正常流程进行处理，直至执行完对目标 UE进行定位阶段；当 H-GMLC 确定出当前阶段为区域变化类位置信息请求中的位置区域事件报告阶 段时， 根据 H-GMLC中配置的 "在对目标 UE进行定位的阶段， 向目标 UE发送 Notification/Verification指示"在 H-GMLC对 LCS Client进行合 法性鉴权的过程中， 即使目标 UE的签约信息设置为需要 LCS系统发送 Notification/Verification指示， H-GMLC根据配置信息， 在向 V-GMLC 发送的 LCS Service Request中 , 并不携带 Notification/Verification指示。 因此， 后续 V-GMLC、 CN在位置区域事件报告阶段， 不会向目标 UE 发送 Notification/Verification指示。
图 3为本发明中实施例一处理流程图， 如图 3所示， 本实施例中， 在 H-GMLC 中配置为 "在位置区域事件报告阶段， 向目标 UE 发送 Notification/Verification指示"， 则在对目标 UE进行定位阶段， 不再向目 标 UE发送 Notification/Verification指示，这样， LCS Client请求目标 UE 位置信息的区域变化类位置信息请求的处理过程包括以下步骤：
步骤 301与步骤 201相同。 步骤 302: R-GMLC收到 LCS Service Request后， 存储 LCS Service Request 中携带的定位指示， 并为当前区域变化类位置信息请求分配 Reference Number, 然后向 H-GMLC转发 LCS Service Request, 该转发 的 LCS Service Request中进一步携带有 Reference Number。 H-GMLC收 到 LCS Service Request后， 对 LCS Client进行合法性鉴权， 确定目标 UE是否允许 LCS系统向该 LCS Client提供其位置信息或位置区域事件 报告， 如果该 LCS Client通过合法性鉴权， 并且目标 UE的签约信息设 置为需要 LCS系统发送 Notification/Verification指示时， H-GMLC根据 LCS Service Request 中的信息， 如根据 LCS Service Request 中的 Reference Number为新分配的 Reference Number, 确定出当前阶段为区 域变化类位置信息请求中位置区域事件报告阶段，然后 H-GMLC根据配 置的 "在位置区域事件报告阶段，向目标 UE发送 Notification/Verification 指示"， 则 H-GMLC向 V-GMLC转发 LCS Service Request, 该转发的 LCS Service Request 中携带有 Notification/Verification 指示 ， Notification/Verification指示用于通知目标 UE对 LCS Client进行私密性 验证； 否则， H-GMLC向 R-GMLC返回鉴权失败消息， R-GMLC拒绝 该 LCS Client对目标 UE发起的区域变化类位置信息请求， 结束当前区 域变化类位置信息请求的处理流程。
步骤 303〜步骤 319与步骤 203〜步骤 219相同。
步骤 320〜步骤 321： H-GMLC收到 LCS Service Request后， 对 LCS
Client进行合法性鉴权，确定目标 UE是否允许 LCS系统向该 LCS Client 提供其位置信息， 如果该 LCS Client通过合法性鉴权， 并且目标 UE的 签约信息设置为需要 LCS 系统发送 Notification/Verification 指示时， H-GMLC 根据 LCS Service Request 中的信息， 如根据 LCS Service Request中的 Reference Number不为新分配的 Reference Number，确定出 当前阶段为区域变化类位置信息请求中位置区域事件报告阶段， 然后
H-GMLC 根据配置的 "在位置区域事件报告阶段， 向目标 UE 发送
Notification/Verification 指示"，， 在向 V-GMLC 发送的 LCS Service
Request中，并不携带 Notification/Verification指示；否则，如果 LCS Client 没有通过鉴权， H-GMLC向 R-GMLC返回鉴权失败消息， R-GMLC拒 绝该 LCS Client对目标 UE发起的区域变化类位置信息请求， 结束当前 区域变化类位置信息请求的处理流程。
步骤 322: V-GMLC收到 LCS Service Request后，向 CN发送 Provide
Subscriber Location, 该 Provide Subscriber Location中携带的内容与 LCS Service Request中携带的内容相对应。
步骤 323〜步骤 330与步骤 224〜步骤 231相同。
图 4为本发明中实施例二处理流程图， 如图 4所示， 本实施例中， 在 H-GMLC 中配置为 "在对目标 UE进行定位阶段， 向目标 UE发送
Notification/Verification指示"， 则在先前的位置区域事件报告阶段中， 不需要向目标 UE发送 Notification/Verification指示， 这样， LCS Client 请求目标 UE位置信息的区域变化类位置信息请求的处理过程包括以下 步骤：
步骤 401与步骤 201相同。
步骤 402: R-GMLC收到 LCS Service Request后， 存储 LCS Service Request 中携带的定位指示， 并为当前区域变化类位置信息请求分配 Reference Number, 然后向 H-GMLC转发 LCS Service Request, 该转发 的 LCS Service Request中进一步携带有 Reference Number。 H-GMLC收 到 LCS Service Request后， 对 LCS Client进行合法性鉴权， 确定目标 UE是否允许 LCS系统向该 LCS Client提供其位置信息或位置区域事件 报告， 如果该 LCS Client通过合法性鉴权， 并且目标 UE的签约信息设 置为需要 LCS系统发送 Notification/Verification指示时， H-GMLC根据 LCS Service Request 中的信息， 如根据 LCS Service Request 中的 Reference Number为新分配的 Reference Number, 确定出当前阶段为区 域变化类位置信息请求中位置区域事件报告阶段，然后 H-GMLC根据配 置的 "在对 目 标 U E 进行定位的阶段， 向 目 标 UE 发送 Notification/Verification指示"， 则 H-GMLC在向 V-GMLC发送的 LCS Service Request中， 并不携带 Notification/Verification指示； 否则， 如果 LCS Client没有通过鉴权， H-GMLC向 R-GMLC返回鉴权失败消息， R-GMLC拒绝该 LCS Client对目.标 UE发起的区域变化类位置信息请求， 结束当前区域变化类位置信息请求的处理流程。
步骤 403: V-GMLC收到 LCS Service Request后， 将该 LCS Service Request 中携带的指定目标区域范围转换为网络能够识别的地域标识， 并向 CN发送定位目标 UE请求（ Provide Subscriber Location )，该 Provide Subscriber Location中携带有目标 UE标识、转换后的以网络地理格式表 示的指定目标区域范围和触发位置报告事件； 与 LCS Service Request中 携带的信息相对应， 该 Provide Subscriber Location中还可携带有上报位 置区域事件报告的次数， 如果需要多次上报位置区域事件报告， 则携带 有周期性上报位置区域事件报告的时间间隔。
步骤 404: CN检测到目标 UE处于空闲模式， 该 CN对目标 UE发 起寻呼， 并对目标 UE进行鉴权和加密， 确定目标 UE是否为合法的网 络用户设备，如果目标 UE为合法的网络用户设备，则继续执行步骤 405; 否则， 结束当前区域变化类位置信息请求的处理流程。
步骤 405〜步骤 418与步骤 206〜步骤 219相同。
步骤 419 ~ 420: H-GMLC收到 LCS Service Request后，对 LCS Client 进行合法性鉴权，确定目标 UE是否允许 LCS系统向该 LCS Client提供 目标 UE的位置信息，如果该 LCS Client通过合法性鉴权，并且目标 UE 的签约信息设置为需要 LCS系统发送 Notification Verification指示时， H-GMLC 根据 LCS Service Request 中的信息， 如根据 LCS Service Request中的 Reference Number不为新分配的 Reference Number,确定出 当前阶段为区域变化类位置信息请求中对目标 UE进行定位的阶段， 然 后 H-GMLC根据配置的 "在对目标 UE进行定位的阶段， 向目标 UE发 送 Notification/Verification指示"， 则 H-GMLC 向 V-GMLC转发 LCS Service Request , 该转发的 LCS Service Request 中进一步携带有 Notification/Verification指示； 否则， H-GMLC向 R-GMLC返回鉴权失 败消息， R-GMLC拒绝该 LCS Client对目标 UE发起的区域变化类位置 信息请求， 结束当前区域变化类位置信息请求的处理流程。
步骤 421〜步骤 430与步骤 222〜步骤 231相同。
总之， 以上所述仅为本发明的较佳实施例而已， 并非用于限定本发 明的保护范围。
