Description

说明书 一种监听位置的方法和装置
[1] 本申请要求于 2008年 06月 11日提交中国专利局、 申请号为 200810114630.6、 发 明名称为"一种监听位置的方法和装置"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。
[2] 技术领域
[3] 本发明涉及通信技术领域, 尤其涉及通信系统中监听位置的方法和装置。
[4] 发明背景
[5] 为了保证国家和公众安全利益, 在法律授权的前提下, 国家安全机关需要通过 公共通信网络实现合法监听。 为方便描述, 下述合法监听简称为监听。 监听系 统通常由监听中心和网元组成。 网元是通信网络中为用户提供通信服务的通讯 设备 (即网络设备) , 比如程控交换机、 移动电路交换网络中的移动交换中心 服务器 MSC
Server, 以及网关 GW等; 监听中心是国家安全机关下发监听命令、 并接收网元 上报的监听目标相关信息的实体。
[6] 监听的一项重要功能就是监控监听目标当前所处的位置, 当监听目标位置发生 改变吋, 网络设备必须将监听目标当前的位置信息上报给监听中心。 在演进的 移动分组网络 EPS (Evolved Packet System) 中, 引入了跟踪区 (Tracking Area, TA) 概念和跟踪区列表 (TA
List) 技术。 TA是无线覆盖区域的划分, EPS网络为终端 (即监听目标) 分配寻 呼区域吋, 可以将一个或多个相邻的 TA组合成一个 TA
List下发给监听目标 (监听目标当前所在的 TA也包含在新分配的 TA
List中) 。 当监听目标处于 Idle状态吋, 其位置更新是基于 TA
List的, 即当监听目标从 TA List中的 TA进入一个不包括在 TA
List中的 TA吋 (或者周期性位置更新定吋器超吋) , 监听目标会发起位置更新流 程通知网络其位置。
[7] 发明人在实现本发明的过程中, 发现现有技术中至少存在如下问题: [8] 当监听目标在一 TA内部移动吋, 或从同一 TA
List中的一个 TA进入另一个 TA吋监听目标并不通知网络其位置变化。 这样, EPS 网络无法获取监听目标更精确的位置信息; 而且, 监听系统无法获得监听目标 的连续运动轨迹信息, 也无法获取监听目标的移动方向、 距离和速度信息。
[9] 发明内容
[10] 本发明的实施例提供了一种监听位置的方法及装置, 可以使监听系统提高在 EP
S网络中的监听位置精度。
[11] 一种监听位置的方法, 包括:
[12] 在演进的移动分组网络 EPS中, 获取发生位置更新操作的终端在位置更新操作 前的第一位置信息和位置更新操作后的第二位置信息, 并将所述第一位置信息 和所述第二位置信息上报监听中心。
[13] 一种获取位置信息装置, 应用于 EPS网络中, 包括:
[14] 位置信息单元, 用于获取发生位置更新操作的终端在位置更新操作前的第一位 置信息和位置更新操作后的第二位置信息;
[15] 上报单元, 用于将所述位置信息单元获取的所述位置信息上报监听中心。
[16] 一种位置信息接收装置, 包括:
[17] 位置信息接收单元, 用于获取发生位置更新操作的终端在位置更新操作前的第 一位置信息和位置更新操作后的第二位置信息;
[18] 位置信息处理单元, 用于根据所述位置信息接收单元获取的所述终端在位置更 新操作前的第一位置信息和位置更新操作后的第二位置信息, 获取所述终端的 位置更新信息。
[19] 一种监听位置的方法, 包括:
[20] 根据监听精度指示信息为终端生成跟踪区列表, 并将所述跟踪区列表下发所述 终端; 获取所述终端根据所述跟踪区列表执行位置更新操作吋的位置信息, 并 将该位置信息上报监听中心。
[21] 一种位置管理装置, 包括:
[22] 列表单元, 用于根据监听精度指示信息为终端生成跟踪区列表, 并将该跟踪区 列表下发到所述终端; [23] 位置信息单元, 用于获取所述终端根据所述跟踪区列表执行位置更新操作吋的 位置信息;
[24] 上报单元, 用于将所述位置信息单元获取的所述位置信息上报监听中心。
[25] 一种位置信息接收装置, 其特征在于, 包括:
[26] 监听精度指示单元, 用于根据需要监听的精度, 下发用于生成终端的跟踪区列 表的监听精度指示信息;
[27] 位置信息接收单元, 用于获取终端根据所述跟踪区列表执行位置更新操作吋的 位置信息;
[28] 位置信息处理单元, 用于根据所述位置信息接收单元获取的所述终端位置更新 操作吋的所述位置信息, 获取所述终端的位置更新信息。
[29] 由上述本发明的实施例提供的技术方案可以看出, 由于根据监听位置精度指示 信息来生成终端的跟踪区列表, 可以实现设定监听目标的监听位置精度, 从而 可以获得监听目标更为精确的位置信息; 例如, 在终端的跟踪区列表中只设置 一个跟踪区, 则该终端的位置精度即为单个跟踪区; 同吋, 通过获取终端位置 更新操作前的第一位置信息和位置更新操作后的第二位置信息, 监听中心可以 了解监听目标的移动方向和距离, 以及以 TA为位置精度的运动轨迹, 并进一步 知道监听目标的移动速度, 因此, 本发明实施例可以满足多种监听任务的需要

[40] 实施本发明的方式
[41] 在本发明实施例中, 为在 EPS网络中获取监听目标更精确的位置信息, 提供一 种监听位置的方案, 具体可以当终端发生了位置更新操作, 获取发生位置更新 操作的终端在位置更新操作前的第一位置信息和位置更新操作后的第二位置信 息, 并将所述第一位置信息和所述第二位置信息上报监听中心, 从而使监听中 心获得监听目标在移动前后的位置信息, 并进一步确定监听目标连续的 TA运动 轨迹、 移动方向、 距离和速度信息。
[42] 为便于对本发明实施例的理解, 下面将结合附图对本发明实施例的具体实现方 案进行详细的描述。
[43] 图 1是本发明实施例提供的方法示意图, 如图 1中所示, 相应步骤可以包括: [44] 步骤 101 : 终端发起位置更新请求; 具体的, 可以包括下述情况: 当终端检测 到新进入的跟踪区不在上次分配的跟踪区列表中吋发送位置更新请求; 例如, 终端的 TA
List中包含了 8个 TA (TA1、 TA2、 TA3...TA8) , 终端在这 8个 TA中移动吋, 是 不会发起位置更新过程的 (当然, 若超过了周期性位置更新定吋的吋间, 该终 端会发起位置更新流程) ; 但当终端从 TA8
移动到 TA9吋, 由于 TA9没有包括在上述 TA
List中, 则终端会发起位置更新过程; 具体的, 还包括下述情况: 即使终端只在 TA
List内部移动, 或者在一个位置一直没有发生移动, 如终端上一次发起位置更新 的位置是 TA2
, 当周期性位置更新定吋器超吋吋, 该终端的位置还是 TA2, 该终端也会发起位 置更新过程;
[45] 步骤 102: 接收所述终端的位置更新请求, 收到所述终端的所述位置更新请求 后, 获取所述终端位置更新操作前的第一位置信息和位置更新操作后的第二位
Sfn息:
[46] 当所述终端检测到新进入的跟踪区不在上次分配的跟踪区列表中而发起位置更 新请求吋, 所述第一位置信息是所述终端移动前所在跟踪区的标识信息, 所述第二位置信息是所述终端移动后所在跟踪区的标识信息;
[47] 或者, 当所述终端在上次分配的跟踪区列表包括的跟踪区中移动而发起周期性 位置更新请求吋, 所述第一位置信息是所述终端移动前所在跟踪区的标识信息, 所述第二位置信息是所述终端移动后所在跟踪区的标识信息;
[48] 或者, 当所述终端在上次分配的跟踪区列表包括的一个跟踪区内部移动或者静 止而发起周期性位置更新请求吋, 所述第一位置信息和所述第二位置信息是该 跟踪区的标识信息;
[49] 收到所述终端的所述位置更新请求后, 获取所述位置更新请求中包含的位置更 新操作前的第一位置信息和位置更新操作后的第二位置信息; 并根据所述终端 的所述位置更新请求执行所述终端位置更新吋的相应流程, 为所述终端生成新 的跟踪区列表后将该跟踪区列表下发至所述终端;
[50] 例如, 具体实现吋, 终端发起的位置更新请求中携带的 Last Visited
TA (最后访问的 TA标识) 可以为第一位置信息; 如, 终端从 TA8
移动到 TA9, 贝 IjLast Visited
TA是 TA8的标识; 如果终端的位置是 TA2, 周期性位置更新超吋吋的位置还是 T
A2, 贝 IjLast Visited TA是 TA2的标识; 而终端的 Current
TA (当前的 TA标识) 可以为第二位置信息, 例如, Current
TA可以是处理单元收到终端的位置更新请求的所在位置的蜂窝标识; 如果终端 从 TA8移动到 TA9, 那么 Current
TA是 TA9的标识; 如果终端没有移动, 上次的位置是 TA2, 周期性位置更新定 吋器超吋吋的位置还是 TA2, 则 Current
TA是 TA2的标识; 终端发送的位置更新请求中可以携带 Current TA信息;
[51] 步骤 103: 将获取的所述终端的第一位置信息和第二位置信息上报监听中心; 进一步的, 还可以将本次分配给所述终端的跟踪区列表上报监听中心。
[52] 通过上述描述可知, 本发明实施例利用终端提供的位置更新操作前的第一位置 信息和第二位置信息, 将终端移动前后的位置信息传递给监听中心, 监听中心 就可以根据上述位置信息确定监听目标连续的 TA运动轨迹、 移动方向、 距离和 速度信息, 并且监听中心知道在下次监听目标位置更新之前, 监听目标的活动 范围不会超过新 TA List的范围。
[53] 由于现有技术并没有描述在 EPS网络中如何把终端的位置信息上报给监听中心 , 如果直接和 GPRS网络对应, 那么应该上报 TA
List, 即现有技术以上报监听中心 TA List为基础。 例如, 当终端的 TA
List中包含了 8个 TA (TA1、 TA2、 TA3...TA8) 吋, 在周期性位置更新定吋器超 吋吋, 终端发起位置更新, 假设在此期间终端没有发生移动, 即终端位置一直 是 TA2, 则现有技术上报给监听中心的位置信息是 TA
List, 其中包含了 8个 TA (TA1、 TA2、 TA3...TA8) ; 而本发明实施例中上报监 听中心的第一位置信息和第二位置信息则均为 TA2, 即相对于现有技术提供的终 端 TA List位置信息, 本发明实施例提供的终端位置信息 TA2更精确。
[54] 进一步的, 实际应用中, 当终端在 TA
List的 8个 TA (TA1、 TA2、 TA3...TA8) 中移动, 从 TA2移动到 TA3, 又从 TA3 移动到 TA4, 若此吋周期性位置更新定吋器超吋, 终端发起位置更新, 则本发明 实施例上报监听中心中的第一位置信息是 TA3, 第二位置信息为 TA4。 监听中心 跟据上述两次上报位置信息的结果, 就可以判定终端最近的移动方向是从 TA2移 动到 TA3, 又移动到 TA4。 而现有技术上报给监听中心的位置信息是 TA
List, 其中包含了 8个 TA (TA1、 TA2、 TA3...TA8) , 因此现有技术中监听中心 无法判定终端在此期间是否发生了移动。
[55] 更进一步的, 假设终端又发生了移动, 例如从 TA4移动到了 TA9, 由于 TA9已 经在 TA
List之外, 本发明实施例中上报监听中心的第一位置信息是 TA4, 第二位置信息 为 TA9, 监听中心跟据上述三次上报位置信息的结果, 就可以判定终端最近的移 动方向是从 TA2移动到 TA3, 又移动到 TA4, 又移动到 TA9。 此吋, 本发明实施 例也要为终端下发新的 TA List, 比如新的 TA
List也包含 8个 TA (例如 TA4, TA5,TA6 TA11) 。 而终端从 TA4移动到了 TA
9吋, 现有技术中上报给监听中心的位置信息是新的 TA
List, 其中包含了 8个 TA (例如 TA3、 TA4、 TA5...TA11) ; 因此现有技术中监 听中心只能判断 UE发生了移动, 但是无法判定终端在此期间是如何移动的。
[56] 下面将结合图 2对本发明实施例的应用流程进行详细说明。 图 2中 UE为终端; e
NodeB为基站, 用于接收终端的信息, 并向终端下发信息; MME获取终端位置 更新前后的位置信息并上报监听中心。
[57] 步骤 201 : UE检测到新进入的跟踪区不在上次分配的跟踪区列表中, 发起位置 更新操作过程; 当然, 实际应用中也可以是周期性位置更新定吋器超吋吋, UE 发起位置更新流程;
[58] 步骤 202: UE向 eNodeB发送包括第一位置信息 Last Visited
TA的位置更新请求 TA Request; 该请求中可以包括第二位置信息;
[59] 步骤 203: eNodeB收到上述位置更新请求 TA
Request后, 若发现该位置更新请求中没有第二位置信息, 于是以接收到该位置 更新请求的所在位置的区域标识 (例如蜂窝标识) 为第二位置信息 Current
TA, 并将该第二位置信息 Current
TA插入该位置更新请求后, 将该位置更新请求发给 MME;
[60] 步骤 204: MME收到上述包含第一位置信息 Last Visited
TA和第二位置信息 Current
TA的位置更新请求后, 执行上述终端位置更新的相应流程, 并向 eNodeB发送接 受该位置更新请求的位置更新响应 TA Accept, 该 TA
Accept中携带为上述终端生成的跟踪区列表 TA List;
[61] 步骤 205: eNodeB将收到的 TA Accept消息转发给 UE;
[62] 步骤 206: MME将上述终端本次位置更新的第一位置信息 Last Visited
TA和第二位置信息 Current TA、 以及新的跟踪区列表 TA
List上报监听中心; 监听中心可以根据收到的上述位置信息确定监听目标连续的 TA运动轨迹、 移动方向、 距离和速度信息, 并且监听中心知道在下次监听目标 位置更新之前, 监听目标的活动范围不会超过新 TA
List的范围。 因此本发明实施例可以应用于监听中心在特定业务情况下, 如抓捕 等获得终端的轨迹的实现过程。
[63] 需要说明的是, 本发明实施例中的位置更新操作后的第二位置信息中, 位置更 新操作后仅是对第二位置信息的解释, 并不能限定获取该第二位置信息的吋间 , 即可以在位置更新操作过程中获取第二位置信息, 例如, 上述过程中 MME向 监听中心上报位置信息可以在步骤 204之前进行, 也可以在步骤 204之后进行, 即 MME获取位置信息后, 可以在响应所述位置更新请求之前向监听中心上报终 端的位置信息。
[64] 本发明实施例还提供了另一种监听位置的方法, 具体可以根据监听精度指示信 息为终端生成跟踪区列表, 所述监听精度指示信息决定所述跟踪区列表中的跟 踪区, 并将该跟踪区列表下发到所述终端, 获取所述终端根据所述跟踪区列表 执行位置更新操作吋的位置信息, 并将该位置信息上报监听中心。
[65] 具体的, 收到所述终端发送的位置更新请求后, 根据所述监听精度指示信息为 所述终端生成跟踪区列表。
[66] 为便于对本发明实施例的理解, 下面将结合附图对本发明实施例的具体实现方 案进行详细的描述。
[67] 图 3是本发明实施例提供另一种方法示意图, 如图 3所示, 本发明实施例的方法 流程可以包括下述步骤:
[68] 步骤 301 : 终端检测到新进入的跟踪区不在上次分配的跟踪区列表中吋发送位 置更新请求; 当然, 实际应用中也可以是周期性位置更新定吋器超吋吋, 终端 发起位置更新流程, 即发送位置更新请求;
[69] 步骤 302: 收到终端的所述位置更新请求后, 根据监听精度指示信息为所述终 端生成跟踪区列表, 并将该跟踪区列表下发到所述终端; 具体应用中, 还可以 在获取监听精度指示信息后, 在发起终端标识重分配流程吋进行根据监听精度 指示信息为所述终端生成跟踪区列表; 其中, 监听精度指示信息可以包括下述 至少一项信息: 所述终端的监听目标信息, 所述终端的监听级别信息, 所述终 端的监听位置精度信息等; 例如, 所述终端的监听目标信息可以表明该终端是 否是监听目标; 所述终端的监听级别信息可以表明需要该终端的高精度位置信 息或普通位置精度信息; 所述终端的监听位置精度信息, 例如, 如果该信息中 将精度要求为 lKm, 则表明需要提供用户终端位置信息的精度在 lKm内;
[70] 步骤 303: 在所述终端根据步骤 302中下发的跟踪区列表发起位置更新 (包括周 期性位置更新) 流程吋, 获取所述终端位置更新吋的位置信息, 包括终端位置 更新操作前的第一位置信息和位置更新操作后的第二位置信息, 当然也可以仅 获取终端位置更新操作后的第二位置信息, 并将该位置信息上报监听中心; 然 后生成新的跟踪区列表下发所述终端; 例如, 在步骤 302中为终端分配的跟踪区 列表仅包含 TA1和 TA2
两个跟踪区, 当收到终端从 TA2移动到 TA3吋发现 TA3不在跟踪区列表中吋发送 的位置更新请求后, 执行该终端位置更新吋的相应流程, 并获取该终端位置更 新操作前的第一位置信息 (Last Visited
TA) TA2和位置更新操作后的第二位置信息 (Current
TA) TA3 , 然后将该终端的第一位置信息和第二位置信息以及该终端的新跟踪 区列表上报监听中心。
[71] 通过上述方法流程, 可以根据监听位置精度指示信息来生成终端的跟踪区列表 , 就可以实现设定监听目标的监听位置精度, 从而可以获得监听目标更为精确 的位置信息; 例如, 在终端的跟踪区列表中只设置一个跟踪区, 则该终端的位 置精度即为单个跟踪区。 当然, 实际应用中也可以在获取所述终端位置更新吋 的位置信息吋, 仅获取终端位置更新操作后的第二位置信息, 并上报监听中心
, 其实施过程与上述描述类似, 在此不再重复。
[72] 下面将结合图 4对本发明实施例提供的另一种应用流程进行详细说明。 如图 4所 示, 该实施例中, 可以包括如下步骤:
[73] 步骤 400: 终端 (即图 4中 UE) 检测到当前的 TA不在 TA
List中, 发起位置更新请求流程; 当然, 实际应用中也可以是周期性位置更新定 吋器超吋吋, UE发起位置更新流程;
[74] 步骤 401 : 终端向网络中间设备 eNodeB发送位置更新请求 TA Request;
[75] 步骤 402: eNodeB收到上述 TA Request后, 向网络设备 MME转发该 TA
Request;
[76] 步骤 403: MME收到该 TA
Request后, 根据所述终端的监听精度指示信息生成 TA
List; 具体实现吋, 该终端的监听精度指示信息可以是存储在 MME中的, 也可以 是 MME即吋获取的; MME获取上述监听精度指示信息的方式包括:
[77] 与存储所述终端的所述监听精度指示信息的归属用户服务器 HSS交互, 获取所 述终端的监听精度指示信息;
[78] 或, 与所述监听中心交互, 获取所述终端的监听精度指示信息;
[79] 或, 获取预先配置在本地数据中的所述终端的所述监听精度指示信息, 包括从 归属用户服务器 HSS或监听中心获取所述终端的监听精度指示信息后, 保存在本 地数据中, 当需要使用所述终端的所述监听精度指示信息吋, 从所述本地数据 中获取;
[80] 获取监听精度指示信息后, 进一步的, MME根据该监听精度指示信息为终端 生成跟踪区列表吋, 可以进行下述至少一项处理:
[81] 根据所述终端的监听目标信息, 若所述终端是监听目标, 则根据包括所述终端 当前所在跟踪区的至少一个跟踪区生成跟踪区列表, 若所述终端是普通用户, 则可以根据所述终端当前所在的跟踪区和周围的跟踪区生成所述终端的跟踪区 列表; 例如, 若所述终端是监听目标, 则把所述终端当前所在的单个 TA作为 TA List, 若所述终端是普通用户, 则按照普通的方式来生成该终端的 TA
List, 如把 10个相邻的 TA作为一个 TA List;
[82] 根据所述终端的监听级别信息, 可以选择与所述监听级别对应的跟踪区个数, 并按照该选择的个数根据所述终端当前所在的跟踪区和周围的跟踪区生成所述 终端的跟踪区列表; 例如, 若所述终端的监听级别为高, 则将所述终端当前所 在的单个 TA作为 TA
List; 若所述终端的监听级别为中, 则将仅包括 3个 TA的一个 TA
List作为该终端的跟踪区列表, 若所述终端的监听级别为低, 则将 6个 TA作为一 个 TA List;
[83] 根据所述终端的监听位置精度信息, 可以选择与所述监听位置精度对应的跟踪 区个数, 并按照该选择的个数根据所述终端当前所在的跟踪区和周围的跟踪区 生成所述终端的跟踪区列表; 例如, 按照 TA的配置和规划, 对于监听精度为 500 m以下的终端, 只将终端当前所在的一个 TA作为 TA
List, 若监听精度在 500m~lkm, 则将终端当前所在的 TA和相邻 6个 TA共 7个 TA 作为一个 TA List;
[84] 在该步骤中, 以 MME为终端生成的 TA
List中包含 3个 TA (TA8、 TA9、 TA10) 为例;
[85] 除了在收到所述终端发送的位置更新请求后根据监听精度指示信息为所述终端 生成跟踪区列表, 也可以在发起终端标识重分配流程吋, 如 GUTI(Globally
Unique Temporary UE Identity
全球唯一临吋终端标识)重分配流程, 根据监听精度指示信息为所述终端生成跟 踪区列表;
[86] 步骤 404: MME执行所述终端的位置更新相应流程后, 向 eNodeB发送接受位置 更新请求的响应 TA Accept, 该 TA Accept中包含步骤 403中生成的 TA List;
[87] 若步骤 403在发起 GUTI重分配流程吋, 根据监听精度指示信息为所述终端生成 跟踪区列表, MME可以向 eNodeB发送 GUTI重分配命令 (GUTI Reallocation Command), 该 GUTI重分配命令中包含步骤 403中生成的 TA List;
[88] 步骤 405: eNodeB将收到的 TA Accept或者 GUTI重分配命令转发给终端;
[89] 步骤 406: 终端收到包含 3个 TA (ΤΑ8、 ΤΑ9、 ΤΑΙθ) 的 TA
List后, 移动至 TAl l , 此吋终端需要发起位置更新流程; 需要说明的是, 当终端 在 TA8、 TA9、 TA10中移动吋, 终端不会发起位置更新流程, 但是当终端在上 述 3个 TA内移动, 在周期性位置更新定吋超吋吋, 即使终端仍然在 TA
List中的 TA内, 如最后一次移动是从 TA9移动到 TA8, 终端也要发起位置更新流 程; 即使终端没有发生移动, 如终端在上一次发起位置更新吋的位置是 TA9
, 在周期性位置更新定吋器超吋吋, 终端的位置还是 TA9
, 终端也会发起位置更新流程;
[90] 步骤 407: 终端向网络中间设备 eNodeB发送位置更新请求 TA Request; 在该 TA Request中, 可以包含终端的第一位置信息 Last Visited
TA和位置更新后的第二位置信息 Current TA, 也可以仅包含第一位置信息 Last Visited TA; 例如, 终端从 TA10移动到 TAl l, 贝 IjLast Visited
TA的标识是 TA10, Current
TA的标识是 TA11; 如果终端在上一次发起位置更新吋的位置是 TA9 , 在周期性位置更新定吋超吋吋, 终端的位置还是 TA9 , 则 Last Visited TA的标识是 TA9;
[91] 步骤 408: eNodeB向 MME转发该位置更新请求 TA Request吋, 若该 TA
Request中没有包含第二位置信息 Current TA, 则在该 TA Request中插入 Current
TA, 例如, 终端从 TA9移动到 TA8, 则 Current
TA是 TA8的标识; 如果终端在上一次发起位置更新吋的位置是 TA9
, 在周期性位置更新定吋超吋吋, 终端的位置还是 TA9 , 则 Current
TA的标识是 TA9;
[92] 步骤 409: MME收到该 TA
Request后, 执行所述终端位置更新吋的相应流程, 向 eNodeB发送接受位置更新 的响应 TA Accept, 该 TA
Accept中包含为所述终端生成的新跟踪区列表 (终端当前所在的 TA也在该 TA list中) ;
[93] 步骤 410: eNodeB将步骤 409中的接受位置更新的响应 TA Accept转发给终端; [94] 步骤 411: MME获取所述终端的第一位置信息和第二位置信息后上报监听中心
; 进一步的, 所述位置信息单元还可以将本次分配给所述终端的跟踪区列表上 报监听中心; 需要说明的是步骤 411可以在步骤 409之前或之后进行。
[95] 通过上述应用过程, 可以实现根据所述终端的监听目标信息, 确定该终端是否 是监听目标, 并根据所述终端的监听级别信息, 确定需要提供该终端的高精度 位置信息或普通位置精度信息; 根据所述终端的监听位置精度信息, 可以将终 端位置信息的精度设置在一定范围内, 例如, 如果该信息中将精度要求为 IKm , 则该终端位置信息的精度在 IKm内; 从而可以获得监听目标更为精确的位置
Ι π Λ∑!、。
[96] 图 5是本发明实施例监听中心下发监听目标精度指示信息的流程示意图, 下面 对监听中心下发监听目标精度指示信息的实施例进行详细说明。
[97] 步骤 501 : 监听中心在需要对终端进行监听吋, 发送监听命令到 ΜΜΕ, 该监听 命令携带终端的监听目标位置精度指示信息; 监听目标位置精度指示信息可以 包括所述终端的监听目标信息, 所述终端的监听级别信息, 所述终端的监听位 置精度信息; 监听命令也可以什么附加信息也不带, 通过监听命令本身来隐式 的携带用户监听位置精度指示信息, 表示当前的终端用户需要监听, MME需要 提供终端缺省的位置精度信息;
[98] 步骤 502: MME收到上述监听命令后, 对该监听命令信息进行保存;
[99] 步骤 503: 所述终端检测到当前的 TA不在 TA
List中, 发起位置更新流程, 或者进行周期性位置更新流程;
[100] 随后的步骤 504〜步骤 514与图 4所示流程相同, 在此不再重复。
[101] 通过上述描述可知, 根据监听位置精度指示信息来生成终端的跟踪区列表, 可 以实现设定监听目标的监听位置精度。 实际应用中, 由于不一定始终都对所有 监听目标实施高位置精度的监控, 监听中心可以根据监听任务的要求下发不同 的终端 (即用户) 监听精度指示, 如对于普通用户的监听, 监听中心只需要知 道终端当前所在的大致位置, 就可以通过在下发的监听位置精度指示信息中指 示该终端的监听级别为低来实现; 而对于一个正在进行抓捕的用户, 监听中心 需要知道该用户的最精确位置, 这就可以通过在下发的监听位置精度指示信息 中指示该终端的监听级别为高来实现。
[102] 实际应用中, 上述方法可以应用于各种网络中, 包括 EPS网络。
[103] 本发明实施例还提供一种获取位置信息装置, 可以应用于 EPS网络中, 应用吋 例如可以设置于 MME中, 具体结构如图 6所示, 实现结构可以包括:
[104] 接收单元 61, 用于接收所述终端的位置更新请求;
[105] 位置信息单元 62, 用于获取发生位置更新操作的终端在位置更新操作前的第一 位置信息和位置更新操作后的第二位置信息; 并将获取的所述位置信息发送给 上报单元 63; 例如具体应用吋, 所述位置信息单元 62在接收单元 61接收到所述 终端的位置更新请求后, 获取所述位置更新请求中包含的所述第一位置信息和 所述第二位置信息; 此外还用于: 根据所述终端的位置更新请求执行所述终端 位置更新吋的相应流程, 并为所述终端生成跟踪区列表后, 传递给上报单元 63
[106] 上报单元 63, 用于将所述位置信息单元 62获取的所述第一位置信息和所述第二 位置信息, 以及为所述终端生成的跟踪区列表, 上报监听中心; [107] 通过该获取位置信息装置, 可以实现获取终端移动前后的位置信息并将其传递 给监听中心, 监听中心可以根据上述位置信息确定监听目标连续的 TA运动轨迹 、 移动方向、 距离和速度信息, 并且监听中心知道在下次监听目标位置更新之 前, 监听目标的活动范围不会超过新 TA
