Definitions

  • the present invention relates to a voice channel optimization processing technique in which a user roams out of a home country, and more particularly, to a user in a roaming country calling a foreign visiting user.
  • BACKGROUND OF THE INVENTION With the rapid increase of international communication services, the round-trip between international long-distance offices can be as follows: Users roam out of the home country (the country to which the user belongs), and go to another country, which is called a roaming country. The domestic user of the roaming country dials the foreign visiting number, and the call continues to be detoured between the international long distance offices.
  • the domestic user of the roaming country calls the foreign caller's voice route diagram.
  • the domestic caller of the roaming country calls the foreign visitor, and the caller connects to the relevant remote switch of the roaming country.
  • Step 101 Then proceed to the roaming country International Exit and Exit Bureau (step 102); then continue to the called user's home country international exit and exit office (step 103); and then continue to the home country called the local gateway mobile exchange center (step 104)
  • the gateway mobile switching center finds that the user roams to the roaming country, and returns the voice channel to the home country international import and export office (step 105); the voice path continues to return to the international gateway of the roaming country (step 106); roaming country international entrance and exit bureau
  • the session is connected to the called party long distance office (step 107); the called party long distance station then connects the session to the called side related switch (step 108).
  • steps 103, 104, 105, 106 in the splicing of the splicing form a roundabout channel. Since the master and the called are in the same country, this roundabout is unnecessary. This seriously wastes network resources and causes the main and called users to generate high unnecessary international call charges.
  • the 3GPP TS 23.079 optimized routing protocol provides a solution for this.
  • Figure 2 is a basic mobile-to-mobile optimized routing framework based on this protocol. The mobile switching center on the calling side and the visited location register on the called side. In the case that the mobile switching center and the home country location register support the optimized routing function, the basic process package is as follows: Step 201: The gateway of the calling party moves directly to the home location register of the called country.
  • Step 202 The home location register of the called country is called to the visited location register of the called party. Providing a roaming number; Step 203: The visited location register of the called party returns a roaming number; Step 204: Returning the home location register of the called country to return the routing information carrying the roaming number to the gateway mobile switching center where the calling party is located;
  • Step 205 The gateway mobile switching center where the calling party is located # ⁇
  • the returning roaming number sends an initial address message to the visited mobile switching center where the calling party is located, and the called party is connected. From this process, there is no loopback for users in the roaming country to call this visiting foreign mobile user, but this protocol has the following problems:
  • the protocol only stipulates the optimized route from the mobile user to the mobile user, but does not specify the optimized route from the fixed user 10 to the mobile user.
  • the foreign mobile user in the roaming country dials the visiting foreign mobile user or will generate a voice path;

优化漫游国国内用户呼叫国外来访用户话路的系统及方法 技术领域 本发明涉及用户漫游出归属国的话路优化处理技术,具体地说, 是涉及一 种漫游国国内的用户呼叫国外来访用户时话路的优化处理系统及方法。 背景技术 随着国际通讯业务的迅速增多,国际长途局间的话路迂回在如下情况下可 肯 H: 用户漫游出归属国(用户所归属的国家), 到另一个国家, 称之为漫游国, 漫游国国内用户拨打此国外来访号码, 此时话路接续在国际长途局间可能产生 迂回。 如图 1一 情况下漫游国国内用户呼叫国外来访用户话路路由示意图所 示, 漫游国国内主叫用户呼叫国外来访用户, 话路经主叫侧相关交换机接续到 漫游国国内主叫侧长途局(步骤 101 ); 然后接续到漫游国国际出入口局(步骤 102 ); 再接续到被叫用户归属国国际出入口局(步骤 103 ); 再接续到归属国被 叫归属所在地关口移动交换中心(步骤 104 ); 关口移动交换中心发现用户漫游 至漫游国, 又将话路返回到归属国国际出入口局(步骤 105 ); 话路继续返回至 漫游国的国际出入口局(步骤 106 ); 漫游国国际出入口局将话路接续到被叫侧 长途局 (步骤 107 ); 被叫侧长途局再将话路接续到被叫侧相关交换机 (步骤 108 )。 从图 1 中明显可以看出, 话路接续中的步骤 103、 104、 105、 106形成 了一个迂回话路。 由于主、 被叫位于同一个国家, 因此这个迂回话路是不必要 的。 这严重浪费了网络资源, 同时让主、 被叫用户产生高额的不必要的国际通 话费。 目前, 3GPP TS 23.079优化路由协议为此提供了一种解决办法, 图 2是基 于此协议的基本移动到移动优化路由框架图, 在主叫侧的关口移动交换中心、 被叫侧的拜访位置寄存器、 拜访移动交换中心以及归属国位置寄存器都支持优 化路由功能的情况下, 其基本过程包 4舌如下: 步聚 201: 主叫所在的关口移动交换中心直接向被叫归属国的归属位置寄 存器发送路由信息; 步骤 202: 被叫归属国的归属位置寄存器向被叫所在的拜访位置寄存器请 求提供漫游号码; 步骤 203: 被叫所在的拜访位置寄存器返回漫游号码; 步驟 204: 被叫归属国的归属位置寄存器向主叫所在的关口移动交换中心 返回携带漫游号码的路由信息;
5 步骤 205: 主叫所在的关口移动交换中心 #^居返回的漫游号码向被叫所在 地的拜访移动交换中心发送初始化地址消息, 接通被叫。 从此流程上看,漫游国国内的用户呼叫此来访的国外移动用户没有迂回路 由, 但是此协议存在以下问题:
1、 协议只规定了移动用户到移动用户的优化路由, 但没有规定固定用户 10 到移动用户的优化路由, 漫游国国内固定用户拨打来访的国外移动用户还是会 产生话路迂回;
2、 此协议要求漫游国和归属国的关口移动交换中心、 拜访位置寄存器和 归属位置寄存器都要支持该协议, 但目前相当多的设备并不支持;
3、 即使所有上述设备都支持 3GPP TS 23.079优化路由协议, 还需要漫游 15 国与归属国通信运营商都开展优化路由业务, 如果某国与另一个国家没有开通 此业务, 那么这两个国家的用户漫游至对方国时, 国际长途局间的迂回就不可 避免会发生。 发明内容 本本发发明明所所要要解解决决的的技技术术问问题题是是为为了了提提供供一一种种优优化化漫漫游游国国国国内内用用户户呼呼叫叫国国 2200 外外来来访访用用户户话话路路的的系系统统及及方方法法,, 使使得得话话路路接接续续只只在在漫漫游游国国国国内内相相关关网网元元上上进进 行行,, 且且不不仅仅适适用用于于移移动动到到移移动动,, 还还适适用用于于固固定定到到移移动动的的呼呼叫叫。。 为为了了解解决决上上述述技技术术问问题题,,本本发发明明提提供供一一种种优优化化漫漫游游国国国国内内用用户户呼呼叫叫国国外外来来 访访用用户户话话路路的的方方法法,, 先先在在漫漫游游国国的的国国内内长长途途局局和和出出入入口口局局之之间间设设置置信信令令拦拦截截装装 置置,, 该该方方法法包包括括如如下下两两 分分::

1、 协议只规定了移动到移动优化路由, 但没有规定固定到移动的优化路 由, 漫游国国内固定用户拨打来访的国外移动用户还会产生话路迂回, 采用本 发明的系统和方法也同样对固定用户拨打国外移动来访用户不会产生迂回路 由;
2、 目前相当多的设备不支持 3GPP TS 23.079优化路由协议; 采用本发明 的系统和方法, 即使设备不支持 3GPP TS 23.079优化路由协议, 也可以达到同 样的效果; 3、 支持 3GPP TS 23.079优化路由协议需要国与国通信运营商之间就开通 ύ化路由业务进行协商, 和任 ^可一个国家的运营商协商条件不满足, 国际长途 局间的迂回就不可避免会发生。 采用本系统和方法, 不需要与其他国运营商协 商, 可以快速应用业务。 附图说明 图 1是一般情况下漫游国国内用户呼叫国外来访用户话路路由示意图; 图 2是基于 3GPP TS 23.079协议的基本移动到移动优化路由框架图; 图 3是本发明所述信令拦截装置实施例应用组网图; 图 4 是本发明用于漫游国国内用户呼叫国外来访用户话路路由实施例示 意图。 具体实施方式 下面结合附图和具体实施方式对本发明作进一步详细说明。 图 3是本发明所述信令拦截装置实施例应用组网图,信令拦截装置位于国 内长途局和国际出入口局之间, 并通过七号信令网与国内长途局、 国际出入口 局相连。 主要包括如下部分: 信令处理前置机, 对外提供七号信令接口, 经七号信令网与国内长途局和 国际出入口局相连, 支持信令转接点功能, 并支持电话应用部分和 ISDN用户 部分协议, 将其它网元发送过来的移动应用部分协议的相关信令转交给业务处 理单元处理, 并将业务处理单元传送过来的移动应用部分协议的相关^"令发送 出去。 业务处理单元, 用以处理移动应用部分协议的相关信令, 并可从数据库获 取所需信息, 及将信息保存到数据库中。 该业务处理单元可以位于在 PC 务 器上, 也可以和信令处理前置机集成在一起。 进一步包括: 位置信息管理子单元, 用于在收到国内长途局发来的位置更新消息后,对 位置更新消息流程进行检测和处理, 如收到位置更新成功响应, 将该来访移动 用户标识及位置相关信息保存在数据库中或更新数据库中的原有数据; 如收到 位置更新失败响应或等待超时, 则不保存所述用户的所述位置信息, 并检查数 据库, 若数据库中具有此用户的位置信息, 则删除此用户相关记录。 呼叫处理子单元, 用于在收到初始化地址消息,确认被叫号码为国外号码 后并在数据库查询到该号码时, 根据记录向被叫用户漫游地的 VLR 查询得到 被叫漫游号码, 将初始化地址信息转发给被叫漫游地的 MSC; 如果发现所述被 叫用户号码在所述数据库中不存在, 则将所述初始化地址消息转发给国际出入 口局。 数据库, 用以存储国外来访用户的号码信息和位置信息, 同时存储有配置 的归属位置寄存器子系统号。 该数据库可以放在信令处理前置机上, 也可以放 在服务器上, 既可以是内存数据库, 也可以是物理数据库。 操作维护台, 用以对装置各部分的配置、 监测和维护。 上述各部分之间, 均利用高速以太网进行通讯。 本发明信令拦截装置可以是独立的装置,也可以在国际出入口局的相关设 备基础上进行设备升级, 而且同一厂家的设备一般只需要进行软件升级即可, 升级容易。 本发明涉及到的通信协议都是国际通用标准协议, 易于开发, 易于和其它 采用标准协议的设备对接, 不存在设备对接的困难。 本发明系统中的长途局与出入口局通过信令拦截装置相连,长途局和出入 口局软硬件都不需要改动, 只需在配置中将邻接局配置改变一下, 各自需要配 置信令拦截装置的局向、 信令点。 即长途局将原来指向出入口局的 gt号码(用 以标识相关交换机的号码)分析修改成指向信令拦截装置, 出入口局将原来指 向长途局的 gt号码分析修改成指向信令拦截装置。 本发明进而提供一种优化漫游国国内用户呼叫国外来访用户话路的方法, 主要由两部分组成。 第一部分是信令拦截装置记录漫游到国内的国外移动用户 的位置信息的方法。 包^ ·以下步骤: 步骤一, 国外移动用户漫游到国内, 漫游用户拜访地的 MSC ( Mobile Switch Center移动交换中心) /VLR ( Visit Location Register拜访位置寄存器) 收到该用户移动终端的位置更新请求后, 向归属国的 HLR ( Home Location Register, 归属位置寄存器)发送位置更新消息; 这个消息经过的地方有: 漫游所在地的 MSC/VLR—〉 国内长途局一〉 国 际出入口局一〉 归属国国际出入口局一〉 归属国国内长途局一〉 HLR, 其中国 内长途局、 国际出入口局、 归属国国际出入口局、 归属国国内长途局作为中间 的信令转接点。 步骤二,信令拦截装置对从国内长途局发送过来的移动应用部分消息进行 拦截, 根据操作码 (位置更新的操作码为 2, 参考 3GPP TS 29.002协议)如识 别出为位置更新消息, 执行下一步; 步骤三, 信令拦截装置对整个位置更新消息流程进行检测和处理。 信令拦截装置需要拦截从国际出入口局发到国内长途局的位置更新响应 消息并进行处理: 如收到位置更新成功响应, 则将该来访移动用户 IMSI ( International Mobile Subscriber Identifier 国际移动用户标识)号码、 MSISDN ( Mobile Station ISDN移动台 ISDN号码) 号码、 MSC号码、 VLR号码全部保存在数据库中; 如果该来访移动用户的号码在数据库中已存在, 则更新数据库中该用户的位置 信息; 如收到的是失败响应或等待超时,则不保存所述用户的所述位置信息,并 检查数据库, 若数据库中具有此用户的位置信息, 则删除此用户相关记录。 第二部分是 ^言令拦截装置对本国用户呼叫国外移动用户的初始化地址消 息进行拦截并处理, 包括如下步骤: 步骤 401 : 漫游国国内用户呼叫国外号码, 主叫所在地的固网交换机 /移 动交换中心分析号码为国外号码, 向国内长途局发送初始化地址消息, 被叫为 国外用户号码; 步 402: 国内长途局分析初始化地址消息中被叫号码为国外号码, 将此 消息转发给信令拦截装置; 步骤 403: 信令拦截装置收到初始化地址消息后, 根据消息中携带的被叫 号码的号码属性及号码前缀分析被叫号码为国外号码, 就向数据库查询被叫号 码是否存在, 若被叫号码存在, 向被叫漫游地的 VLR (拜访位置寄存器)发送 提供漫游号码请求消息; 若用户号码在数据库中不存在,则信令拦截装置将初始化地址消息转发给 国际出入口局。 另外,信令拦截装置在发送的漫游号码请求消息中,将装置的子系统号设 为归属位置寄存器的子系统号, 用以其模拟归属位置寄存器 HLR的行为。 步驟 404 被叫所在拜访位置寄存器收到漫游号码请求消息后, 向信令拦 截装置返回漫游号码; 步骤 405 信令拦截装置根据漫游号码,将初始化地址信息转发给被叫漫 游所在地的拜访移动交换中心, 从而接通被叫。 上述流程中,若被叫用户所在的拜访位置寄存器向信令拦截装置返回由于 用户不存在造成的取漫游号码失败响应 则信令拦截装置将初始化地址消息转 发给国际出入口局, 同时删除该用户在信令拦截装置的记录信息, 该用户可能 已经漫游出国内了。 综上所述, 采用本发明所述方法, 当漫游国国内的用户在呼叫国外来访用 户时, 话路接续只在漫游国相关网元上进行, 避免了话路在国际长途局间的迂 回。
