Description

SIP终端注册及业务处理的方法、 ¾ 目关设备
本申请要求于 2011 年 03 月 28 日提交中国专利局、 申请号为 201110075196.7、发明名称为 "SIP终端注册及业务处理的方法、及相关设备" 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。
技术领域
本发明涉及通信技术领域,具体涉及会话初始协议( SIP: Session Initiation Protocol )终端注册及业务处理的方法、 及相关设备。
背景技术
互联网协议多媒体子系统( IMS: IP Multimedia Subsystem )是第三代移 动通信标准化伙伴项目( 3GPP: 3rd Generation Partnership Project )版本 5 ( R5: Release 5 )提出的提供互联网协议( IP: Internet Protocol ) 多媒体业务的子系 统, 主要采用 SIP、 Diameter协议等协议, 与上层控制子系统和具体的接入技 术无关。 由于 IMS是与接入技术无关的网络, 因此不论用户通过使用非对称 数字用户线(ADSL: Asymmetric Digital Subscriber Line ) 的计算机接入, 还 是使用宽带码分多址( WCDMA: Wideband Code Division Multiple Access )手 机等无线方式接入, 都可体验相同的业务。
IMS核心网 (IMS CN )允许一个用户拥有多个终端, 例如手机、 固话、 SIP终端等, 并且可以同时呼叫用户的多个终端。 其中, SIP终端介于手机和 固话之间, 首先和固话一样只能接入归属地的核心网, 其次具备移动能力, 可 以通过因特网 (Internet ) 实现拜访地到归属地的网络互联, SIP终端可以是个 人电脑 (PC: Personal Computer )软终端等。
SIP终端通常使用 SIP/IP方式接入核心网, SIP号码( SIP URI )按照协议 规定允许用户自定义, 因此 PC软终端的 SIP号码和传统电话号码不同, 所以 在用户漫游后, 除非在用户开户时分配包含地理信息的 SIP号码, 否则无法通 过路由配置为 SIP终端提供的漫游功能,而如果在用户开户时分配包含地理信 息的 SIP号码, 则会损失 SIP业务特性。 为了保持 SIP业务特性, 现有的一种 处理方式是 SIP终端通过 Internet直接向归属地的核心网注册, 并进行业务处 理。
在 SIP终端通过 Internet直接向归属地的核心网注册时, SIP终端的业务 控制和媒体层面信令都需要经过 Internet,而各地或各国的 Internet网络质量参 差不齐, 因此将会导致业务质量无法得到保证。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清 楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而不是 全部的实施例。基于本发明中的实施例, 本领域普通技术人员在没有作出创造 性劳动前提下所获得的所有其他实施例, 都属于本发明保护的范围。
先介绍本发明实施例提供的 SIP终端注册的方法,图 1描述了本发明一个 实施例提供的 SIP终端注册的流程, 包括:
101、 第二业务服务器接收 SIP终端从第一网络发送的登录请求。
其中, 第二业务服务器归属于第二网络。
例如, 第一网络可以为 SIP终端的拜访地网络, 第二网络可以为 SIP终端 的归属地网络。
102、 第二业务服务器将所述第一核心网网元的地址发送给 SIP终端, 以 使 SIP终端向第一核心网网元进行注册以及进行业务请求;并且向第一业务服 务器发送 SIP终端的业务数据,以使第一业务服务器根据业务数据对业务请求 所请求的业务进行业务处理。
其中,第一核心网网元归属于第一网络,第二业务服务器归属于第二网络。 在本发明的一个实施例中, 第一核心网网元可以为代理-呼叫会话控制功能
( P-CSCF: Proxy-Call Session Control Function ) 实体等 IMS核心网的网元。
具体地,第二业务服务器根据接收的登录请求获取第一核心网网元的地址。 一方面, 第二业务服务器可以从登录请求中获取 SIP终端登录的登录地址, 从 而根据登录地址确定 SIP终端当前所处的第一网络,再从预置的核心网网元的 地址列表中查找第一网络对应的第一核心网网元的地址。核心网网元的地址列 表中包括所有可能与第二网络有业务关系的网络的核心网网元的地址。另一方 面,第二业务服务器根据 SIP终端的登录地址确定 SIP终端当前所处的第一网 络后,可以从预置的业务服务器的地址列表中查找第一网络对应的第一业务服 务器的地址,再与第一业务服务器进行通信获得第一核心网网元的地址, 业务 服务器的地址列表中包括所有可能与第二网络有业务关系的网络的业务服务 器的地址, 可以使核心网网元的地址不用直接暴露给其他网络的业务服务器, 提高网络安全性。
SIP终端的业务数据中包括一些不适合发送的业务数据, 如涉及大量群组 信息的企业 Centrex业务等, 此时第二业务服务器可以仅将适合迁移的业务数 据发送给第一业务服务器,第二业务服务器还可以进一步根据该适合发送的业 务数据为第一核心网网元配置 SIP终端的初始过滤准则 (iFC: Initial Filter Criteria ), 并将配置的 iFC发送给第一核心网网元, 以使第一核心网网元根据 该 iFC进行业务控制; 当然,也可以由第一业务服务器在接收到适合发送的业 务数据后,根据该适合发送的业务数据为第一核心网网元配置 SIP终端的初始 过滤准则, 并将配置的 iFC发送给第一核心网网元, 以使第一核心网网元根据 该 iFC进行业务控制。
一方面,第二业务服务器在接收到 SIP终端从第一网络发送的登录请求后, 可以主动地向第一业务服务器发送 SIP终端的业务数据。 另一方面, 第二业务 服务器也可以在接收了业务数据发送请求后,才向第一业务服务器发送 SIP终 端的业务数据,该业务数据发送请求可以由 SIP终端的用户或运营商客服登录 特定的系统后触发发送, 例如, SIP终端的用户或运营商客服可以登录第二业 务服务器触发发送该业务数据发送请求, 其中,登录第二业务服务器可以是通 过浏览器的远程登录也可以是直接本地登录第二业务服务器。
从上可知,本实施例中第二业务服务器在接收到 SIP终端从第一网络发送 的登录请求后, 可以引导 SIP终端向第一核心网网元进行业务请求, 还可以将 SIP终端的业务数据发送给第一业务服务器, 使第一业务服务器根据业务数据 为 SIP终端进行业务下发, 从而使 SIP终端直接从第一网络获得业务, 避免通 过第一网络和第二网络之间的 Internet网络获得业务, 使业务质量可以得到保 证; 同时, SIP终端可以直接向第一核心网网元进行注册, 使得 SIP终端可以 根据自己的需要申请 SIP号码,只要申请的 SIP号码满足协议的规定都不会影 响本发明实施例的实现, 因此不会损失业务特性。
在本发明另一个实施例提供的 SIP终端注册的方法中,第二业务服务器在 向第一核心网网元发送 SIP终端的业务数据后,如果接收到 SIP终端从第二网 络或第三网络发送的登录请求,则向第一业务服务器发送删除该 SIP终端的业 务数据的请求。 如果接收到 SIP终端从第二网络或第三网络发送的登录请求, 则说明 SIP终端已经离开了第一网络, 可以向第一业务服务器发送删除该 SIP 终端的业务数据的请求, 使第一业务服务器删除该 SIP终端的业务数据,释放 存储该业务数据的存储空间。
在本发明另一个实施例提供的 SIP终端注册的方法中,第二业务服务器在 接收了 SIP终端从第一网络发送的登录请求后,可以进一步判断是否有另一个 SIP终端使用与该 SIP终端相同的 SIP号码第二核心网网元处于注册状态, 第 二核心网网元归属于第二网络;如果是,则向第二核心网网元发送去注册请求, 以使该另一个 SIP终端在第二核心网网元去注册,从而确保一个 SIP号码在同 一时间只通过一个 SIP终端在一个核心网注册, 确保业务能够路由至正确的 SIP终端。
再介绍本发明实施例提供的业务处理的方法,图 2描述了本发明一个实施 例提供的业务处理的流程, 包括:
201、 第一核心网网元接收已注册的 SIP终端发送的业务请求。
其中, 第一核心网网元归属于第一网络, SIP终端归属于第二网络。
例如, 第一网络可以为 SIP终端的拜访地网络, 第二网络可以为 SIP终端 的归属地网络。
其中, 已注册的 SIP终端可以采用本发明实施例提供的 SIP终端注册方法 在第一核心网网元注册。
202、 第一核心网网元将业务请求转发给第一业务服务器, 以使第一业务 服务器根据 SIP终端的业务数据对业务请求所请求的业务进行业务处理。
该业务数据由第一业务服务器预先从第二业务服务器获得,第一业务服务 器归属于第一网络, 第二业务服务器归属于第二网络。 具体地, 该业务数据可 以由 SIP终端在采用本发明实施例提供的 SIP终端注册方法在第一核心网网元 进行注册时, 由第二业务服务器发送给第一业务服务器。
从上可知,本实施例中第一核心网网元可以接收归属于第二网络的 SIP终 端的注册, 并且可以将 SIP终端发送的业务请求转发给第一业务服务器, 使第 一业务服务器可以根据业务数据为 SIP终端进行业务下发,从而使 SIP终端直 接从第一网络获得业务, 避免通过第一网络和第二网络之间的 Internet网络获 得业务, 使业务质量可以得到保证; 同时, SIP终端可以直接向第一核心网网 元进行注册, 使得 SIP终端可以根据自己的需要申请 SIP号码, 只要申请的 SIP号码满足协议的规定都不会影响本发明实施例的实现, 因此不会损失业务 特性。
在本发明另一个实施例提供的业务处理的方法中,第一核心网网元将业务 请求转发给第一业务服务器前,可以进一步根据预先配置的 SIP终端的初始过 滤准则,对业务请求所请求的业务进行判断; 只有在判断业务请求所请求的业 务为第一网络业务时, 才将业务请求转发给第一业务服务器; 在判断业务请求 所请求的业务为第二网络业务时,则通过第二核心网网元将业务请求转发给第 二业务服务器, 以使第二业务服务器对业务请求所请求的业务进行业务处理, 其中, 第二核心网网元归属于第二网络。
图 3描述了本发明另一个实施例提供的业务处理的信令流程,本实施例中, SIP终端、 第二业务服务器、 第二核心网网元归属于第二网络, 第一业务服务 器和第一核心网网元归属于第一网络, 其中, 第一网络具体可以为 SIP终端的 拜访地网络, 第二网络具体可以是 SIP终端的归属地网络, 该实施例包括:
301、 SIP终端向第二业务服务器发送登录请求。
302、 第二业务服务器向 SIP终端发送登录响应, 该登录响应包括第一核 心网网元的地址。
具体地, 第二业务服务器可以根据登录请求获取第一核心网网元的地址, 第二服务器获取第一核心网网元的过程可以参考 102, 此处不再赘述。
303、 第二业务服务器向第一业务服务器发送 SIP终端的业务数据。
其中,第二业务服务器可以将 SIP终端的全部业务数据发送给第一业务服 务器; 另一方面, 在 SIP终端的业务数据中仅有部分适合发送时, 第二业务服 务器也可以仅将 SIP终端的部分业务数据发送给第一业务服务器。本实施例以 第二业务服务器仅将 SIP终端的部分业务数据发送给第一业务服务器为例进 行描述。
其中, 303也可以在 302之前执行, 或与 302同时执行。 304、 第一业务服务器为第一核心网网元配置 iFC。
305、 SIP终端根据第一核心网网元的地址向第一核心网网元发送基于 SIP 的注册请求。
306、 第一核心网网元向 SIP终端发送基于 SIP的注册响应。
注册响应携带 SIP终端注册成功或失败的信息, 在本实施例中, ¾殳 SIP 终端注册成功。
307、 SIP终端向第一核心网网元发送基于 SIP的业务请求。
308、 第一核心网网元对业务请求所请求的业务进行判断; 如果是第一网 络业务, 进入 309; 如果是第二网络业务, 进入 310。
具体地,第一核心网网元可以根据 iFC对业务请求所请求的业务进行判断。
309、 第一核心网网元将业务请求转发给第一业务服务器。
第一业务服务器在接收了业务请求后,可以根据业务请求所请求的业务做 相应的业务处理; 具体地, 根据业务请求所请求的业务不同, 第一业务服务器 可以进行不同的业务处理, 例如在该业务请求为呼叫请求时, 第一业务服务器 可以接续呼叫。
310、 第一核心网网元将业务请求转发给第二核心网网元。
311、 第二核心网网元将业务请求转发给第二业务服务器。
第二业务服务器在接收了业务请求后,可以根据业务请求做相应的业务处 理; 具体地, 根据业务请求所请求的业务不同, 第二业务服务器可以进行不同 的业务处理,例如在该业务请求为呼叫请求时,第二业务服务器可以接续呼叫。
从上可知,本实施例中第一核心网网元可以接收归属于第二网络的 SIP终 端的注册, 并且可以将 SIP终端发送的业务请求转发给第一业务服务器, 使第 一业务服务器可以根据业务数据为 SIP终端进行业务下发,从而使 SIP终端直 接从第一网络获得业务, 避免通过第一网络和第二网络之间的 Internet网络获 得业务, 使业务质量可以得到保证; 同时, SIP终端可以直接向第一核心网网 元进行注册, 使得 SIP终端可以根据自己的需要申请 SIP号码, 只要申请的 SIP号码满足协议的规定都不会影响本发明实施例的实现, 因此不会损失业务 特性。 并且, 在业务请求所请求的业务为第二网络业务时, 也可以由第二业务 服务器为 SIP终端下发业务, 从而确保 SIP终端所请求的业务得到下发。 需要说明的是, 对于前述的各方法实施例, 为了筒单描述, 故将其都表述 为一系列的动作组合,但是本领域技术人员应该知悉,本发明并不受所描述的 动作顺序的限制,因为依据本发明,某些步骤可以采用其他顺序或者同时进行。 其次, 本领域技术人员也应该知悉,说明书中所描述的实施例均属于优选实施 例, 所涉及的动作和模块并不一定是本发明所必须的。
