- the length of time depends on the effective time of the TMSI set by the switch. That is to say, if the method is opened by the method of the present invention, if the user has not been outside the network or the incoming call of the VLR outside the network, there is no call out to the network or the VLR in the network.

However, once one of the above behaviors is present, the method of the present invention can remember the correspondence between its initial MSISDN and TMSI, and the corresponding relationship can be maintained. This is an accumulation process.
- the following action trigger signaling is required to obtain the location information of the user, thereby performing positioning:
- this location update is automatically generated by the network side, and its frequency can be set in the switch.
- the detection rate of the user cell location is not high, and the guess rate is used to detect the probability of the MSISDN and the cell location relationship, but with time Accumulation, its detection rate will gradually increase.
- the cell positioning method of the mobile user comprehensively and comprehensively considers the association characteristics between various protocol types from a system aspect, and proposes a unified and efficient method for extracting the correspondence relationship between the user MSISDN and the cell, thereby effectively

现有技术中的通讯系统在社会各个领域中已得到了日益广泛的应用, 改变 了人们传统的生活、工作方式, 通讯技术也在人们需求的推动下, 得到快速的 发展。其中运营商根据用户的行为属性而定制各种特性化的服务已经得到了广 泛的应用。
目前通过 7号信令监测提供用户位置信息的技术有如下几个方面: 大区短信欢迎。其主要的工作原理是通过监测 VLR (拜访位寄存器, Visitor Location Register, 以下简称 VLR) 和 HLR (归属位寄存器, Home Location Register, 以下简称 HLR)之间的接口以获取用户跨 VLR的行为, 从而实现大 区短信欢迎。但其能定位的最小范围是 VLR所包括的区域,不能区分小区级别 的范围。
目前已有运营的小区短信系统, 如中国移动的山东移动小区短信系统, 其 工作原理是通过监测 A接口, C接口和 D接口, 主要是通过 A接口获取用户的 小区位置信息, 但其 A接口上仅限于走 IMSI (国际移动用户标识,

以下结合附图, 将对本发明的各较佳实施例进行较为详细的说明。
本发明的一种利用七号信令实现移动用户小区定位的方法, 所涉及的接口 协议主要包括: ISUP (综合业务数字网用户部分, ISDN User Part, 以下简称 ISUP). MAP (移动应用部分, Mobile Application Part, 以下简称 MAP)以及 BSSAP (基站系统应用部分, Base Station System Application Part, 以下简 称: BSSAP)。 其中 ISUP协议接口主要是监测呼叫接续, 可以获得接续中的主 叫用户号码和被叫用户号码,其中如果被叫用户为移动用户,则被叫号码可能 为被叫的漫游号码。 MAP协议接口主要是监测位置更新事件, 发路由信息事件 和提供漫游号码事件, 目的是获取用户的 MSISDN (移动台国际 ISDN号码, Mobile Station International ISDN Number,也就是通常所说的手机号码) 与: EMSI的对应关系, MSRN (移动台漫游号码, Mobile Station Roaming Number) 与 MSISDN的对应关系。 Gsm A接口主要是为了获取用户 TMSI与位置信息的对 应关系, 同时获取呼叫中的主叫号码和被叫号码的对应关系。可以看出, 单独
监测其中的一个接口是很难实现用户定位需求的。而且 BSSAP信令多数采用的 是 TMSI号码,无法直接得到用户 TMSI与 MSISDN的对应关系。针对这种现状, 本发明提出了一种高效通用的移动用户小区定位方法, 该方法针对现网中 BSSAP信令使用 TMSI或者: [MSI都适合。 可以通过移动用户位置更新, 起呼, 终呼等用户行为关联出 TMSI与 MSISDN的对应关系,从而进一步实现移动用户 小区定位。
如图 1所示为移动用户小区定位方法流程图, 其中第一步 101信令采集和 第二步 102事件合成对于本专利实现的各种情况是一致的,后续的步骤根据用 户的行为类型的不同, 处理方式有所不同。
具体步骤如下:
步骤 101 :对七号信令的 A接口, D接口, E接口和 G接口的数据进行采集; 步骤 102: 对采集后的数据进行事件合成;
步骤 103: 对 A接口事件, D接口事件, E接口事件和 G接口事件进行关联 以得到移动用户 TMSI与 MSISDN的对应关系;
步骤 104: 通过 A接口事件中的 TMSI重分配消息, 提取新旧 TMSI号, 更 新 TMSI与 MSISDN的对应关系;
步骤 105:从 A接口包含位置信息的事件中获取 TMSI号码和与之对应的小 区信息;
步骤 106: 将所述步骤 105中的 TMSI号码与小区的对应关系与所述步骤 104中的 TMSI与 MSISDN的对应关系通过 TMSI号码关联, 即得到 MSISDN与该 MSISDN所在的小区的对应关系, 从而得到移动用户的小区位置信息。
下面针对不同的用户行为模式, 以描述实施的步骤。
一、 用户跨 VLR位置更新行为
在该部分, 其实现原理如图 2, 示明了用户跨 VLR位置更新的简易过程。 其过程如下:

203、 用户原先所在的 MSC向用户所在的 MSC反馈发标识;
204、 用户所在的 MSC向用户所在的 BSC反馈位置更新结果。
图中两条竖直的虚线部分为本发明所监测区域,通过原先 TMSI号码关联 A 接口位置更新事件和 G接口发标识事件可获得用户 TMSI与: [MSI的对应关系, 再根据 A接口其它事件和 MSISDN与 IMSI的对应关系可以得到移动用户的小区 位置信息。

331、 从 A接口位置更新 TDR中提取用户原先 TMSI与现在 TMSI的对应关 系;
332、 从 G接口发标识 TDR中提取用户原先 TMSI与頂 SI的对应关系;
333、 从 D接口位置更新事件中提取用户 MSISDN与 IMSI对应关系;
34、 通过第 332步和第 333步, 由: EMSI查找关联第 332步和第 333歩的 结果, 得到用户原先 TMSI与 MSISDN的对应关系;
35、 通过第 331步和第 34步, 由原先 TMSI査找关联第 331和第 34步的 结果, 得到用户现在 TMSI与 MSISDN对应关系;
36、从 A接口 TMSI重新分配事件中提取原先 TMSI与新的 TMSI对应关系, 根据第 35步的结果, 更新 TMSI与 MSISDN对应关系;
37、 分析 A接口其它包含位置信息的事件, 如周期位置更新, 正常位置更 新, 起呼, 终呼, 发短信, 收短信等, 提取用户现在 TMSI和与它对应的小区 位置信息;
38、 对第 37步中的结果通过 TMSI査找第 36步的结果, 得到用户 MSISDN 和与之对应的小区位置信息, 从而实现了用户的小区定位。
二、 移动用户起呼呼叫网内 VLR以外的用户
在该部分, 其实现原理如图 4, 图 4示明了移动用户起呼呼叫网内 VLR以 外用户的简易过程, 其过程如下:

402 MSC1通过被叫号码找到被叫注册的 HLR并向 HLR发发路由消息来获取 被叫用户路由;
403 HLR会将被叫路由返回给 MSC1,告知被叫用户现在在 MSC2;
404 MSC1发起起呼消息到 MSC2,将呼叫接续到 MSC2。
图中两条竖直的虚线之间部分为本发明所监测的区域, 通过被叫 MSISDN 和被叫 MSRN关联 A接口起呼事件, E接口起呼事件和 D接口发路由信息事件, 从而获得用户 TMSI与 MSISDN的对应关系,再根据 A接口其它事件可以得到移 动用户的小区位置信息。 具体实施步骤如图 5所示, 步骤如下:

533、 从 D接口发路由信息 TDR中提取被叫 MSISDN与被叫 MSRN的对应关 系;
54、 将上述第 531步,第 532步,第 533步的结果综合, 根据被叫 MSISDN 和被叫 MSRN关联, 得到主叫用户现在 TMSI与 MSISDN对应关系;
55、从 A接口 TMSI重新分配事件中提取原先 TMSI与新的 TMSI对应关系, 更新第 54步的结果, 得到用户最新 TMSI与 MSISDN对应关系;
56、 分析 A接口其它包含位置信息的事件, 如周期位置更新, 正常位置更 新, 起呼, 终呼, 发短信, 收短信等, 提取用户现在 TMSI和与它对应的小区 位置信息;
57、 对第 56步中的结果通过 TMSI查找第 55步的结果, 得到用户 MSISDN 和与之对应的小区位置信息, 从而实现了用户的小区定位。
三、 移动用户起呼呼叫网外用户
在该部分, 其实现原理如图 6, 图 6示明了移动用户起呼呼叫网外用户的 简易过程, 其过程如下:
601 用户所在 BSC向 MSC1发起起呼消息;
602 MSC1通过被叫号码判断为网外呼叫, 发起起呼消息到 MSC2 (网内或 网外关口局) ,将呼叫接续到 MSC2。
图中两条竖直的虚线部分为本发明所监测区域, 通过被叫号码关联 A接口 起呼事件和 E接口起呼事件,从而获得用户 TMSI与 MSISDN的对应关系,再根 据 A接口其它事件可以得到移动用户的小区位置信息。具体的实施步骤如图 7, 步骤如下:
71、 首先对七号信令的数据进行采集;
72、 对采集到的数据放入分析模块进行正常 CDR/TDR合成分析, 其具体合 成方法同具体实施方式的第一个实例;
73、 上两步完成后, 并行处理如下两步:
731、从 A接口起呼 CDR中提取用户最新 TMSI与被叫用户号码的对应关系;
732、 从 E接口呼叫 CDR中提取主叫 MSISDN与被叫用户号码的对应关系; 74、 将第 731歩和第 732步的结果通过被叫用户号码关联, 得到主叫用户 现在 TMSI与 MSISDN对应关系;
75、从 A接口 TMSI重新分配事件中提取原先 TMSI与新的 TMSI对应关系, 更新第 74步的结果, 得到用户最新 TMSI与 MSISDN对应关系;
76、 分析 A接口其它包含位置信息的事件, 如周期位置更新, 正常位置更 新, 起呼, 终呼, 发短信, 收短信等, 提取用户现在 TMSI和与它对应的小区 位置信息;
77、 对第 76步中的结果通过 TMSI査找第 75步的结果, 得到用户 MSISDN 和与之对应的小区位置信息, 从而实现了用户的小区定位。
本发明不是对所有的 A接口用户事件都能够关联到其 MSISDN与小区位置 的对应关系,是有一定的限制的,首先必须有如下的动作之一才能够关联出用 户 MSISDN与 TMSI的对应关系:
1 呼出电话到网外, 或者是网内本 VLR以外;
2 网外或者是网内本 VLR以外的呼入电话;
3 跨 VLR位置更新;
4关机后长时间再开机, 时间的长短视交换机设置的 TMSI有效时间为准。 也就是说, 如果采用本发明的方法开通系统后, 如果用户一直没有网外或 者是网内本 VLR以外的电话呼入, 也没有电话呼出到网外或者是网内本 VLR
以外, 也没有进行跨 VLR位置更新, 同时也不关机的话, 采用本发明的方法是 关联不到用户 MSISDN与 TMSI的对应关系的。 但一旦有以上行为当中的一种, 本发明方法就能记住其初始的 MSISDN与 TMSI的对应关系,就能够对其对应关 系进行维护了, 这是一个累加的过程。
有了 MSISDN与 TMSI的对应关系后, 还需要如下的动作触发信令才能得到 用户的位置信息, 从而进行定位:
1 用户开机 /关机动作;
2 呼入 /呼出;
3 收短信 /发短信;
4位置区级别的位置更新;
5周期性位置更新, 此位置更新由网络侧自动产生, 其频率可在交换机设 置。
从上面的描述可以看出, 采用本发明的方法在初始状态时, 用户小区定位 的检测率是不高的, 该捡测率用于检测到 MSISDN与小区位置关系的概率, 但 随着时间的累积, 其检测率会逐渐提高。
尽管上面结合附图对本发明所述方法的几个具体实施例进行了描述, 但是 本方法并不局限于上述的具体实施方式, 也不局限于七号信令监测的网络类 型, 上述的具体实施方式仅仅是示意性的, 而不是限制性的, 本领域的普通技 术人员在本方法的启示下,在不脱离本方法宗旨和权利要求所保护的范围情况 下, 还可以作出各种可能的变形, 这些均应属于本方法的保护之内。 工业应用性
本发明所述移动用户的小区定位方法从系统方面上全面、综合地考虑各种 协议类型之间的关联特性, 提出一种统一的、 高效的提取用户 MSISDN与小区 的对应关系的方法,从而有效的解决了移动用户的小区定位的问题;该方法监 测接口标准统一,考虑完备, 可集中监测, 且对现网在运行的主设备没有任何 影响, 能够推广到全省乃至全国监测。本发明方法可适合通讯领域中的涉及 7 号信令监测的领域, 本发明方法同样适合存在类似问题的其他各领域。
