Description

一种号码关联的实现方法及系统 技术领域
本发明涉及无线通信技术领域, 尤其涉及一种号码关联的实现方法及 系统。 背景技术
IP多媒体子系统(IP Multimedia Subsystem, IMS )是第三代合作伙伴 组织( 3rd Generation Partnership Project, 3 GPP )定义的下一代网络的标准, 其显著特点是采用会话初始协议(Session Initiation Protocol, SIP )体系, 通讯与接入无关, 可以具备多种媒体业务控制功能与承载能力分离, 呼叫 与会话分离, 应用与服务分离, 业务与网络分离, 以及移动网与因特网业 务融合等多种能力。
IMS的提出顺应了通讯网融合发展的趋势, IMS的网络架构如图 1所 示, 包括: 用户设备(User Equipment, UE ) /接入设备, 代理呼叫会话控 制功能实体(Proxy Call Session Control Function, P-CSCF ), 查询呼叫会话 控制功能实体(Interrogating Call Session Control Function, I-CSCF ), 服务 呼叫会话控制功能实体( Serving Call Session Control Function, S-CSCF ), 归属用户服务器( Home Subscriber Server, HSS )以及未表示在图 1中的应 用服务器 ( Application Server, AS )。
公有用户标识( Public User Identity, PUI )是用户在 IMS网络中通信 的标识。 为了满足某些业务应用的特定场景的要求, 在 IMS中引入了别名 组的概念, 这里所述别名组是指用户的具体的哪几个号码互为别名的信息, 例 ^口: PUI 1和 PUI 2互为另 'J名, 即 PUI 1和 PUI 2代表同一个用户。
同一个别名组中的通用资源标志符( Uniform Resource Identifier, URI ) 具有以下特征: 属于同一个隐式注册集; 签约的业务相同; 对每一种业务 场景配置要完全相同。
在 IMS架构中, S-CSCF通过向 HSS获取用户数据信息, 可以得到别 名组信息, 具体流程如图 2所示, 包括下述步骤:
S201, UE向 P-CSCF发送注册请求, 所述注册请求中带有公有用户标 识;
S202, P-CSCF收到注册请求时, 定位本地用户数据, P-CSCF通过域 名系统(Domain Name System, DNS ) 查询或者其它方法找到 I-CSCF, 并 将注册请求转发到 I-CSCF;
S203, I-CSCF向 HSS发送 S-CSCF分配请求( UAR ),要求分配 S-CSCF;
5204, HSS向 I-CSCF返回 S-CSCF分配响应 (UAA ), 所述 S-CSCF 分配响应中包含有为该用户分配的 S-CSCF地址 /名称, 及用户数据包括用 户的别名组信息;
5205, I-CSCF将注册请求消息发送到选定的 S-CSCF;
S206, S-CSCF发送获取用户数据请求( SAR )给 HSS,获取用户数据;
5207, HSS返回获取用户数据响应(SAA ), 携带用户数据, 其中包括 用户的别名组信息;
5208, S-CSCF进行相应处理,向 I-CSCF返回注册成功响应,如 200OK, 响应中包括 PUI信息; 同时本地保存用户的别名组信息;
S209, I-CSCF将注册成功响应转发给 P-CSCF;
5210, P-CSCF收到注册响应消息后, 保存用户数据到本地, 即将 PUI 信息保存到本地;
5211 , P-CSCF将注册成功响应转发给 UE。
通过别名组技术, S-CSCF能够实现不同号码的关联。 例如: PUI 1和 PUI 2互为关联号码, 其中, PUI 1为 sip: +861013813812345@bj.com.cn; PUI 2为 tel: +861013813812345。 对于某些功能下, 需要使用关联号码。 以 监听功能为例,假设对 PUI 1进行布控,由于 PUI 1和 PUI 2号码业务相同, 性质相同,因此必须同时监听 PUI 1和 PUI 2,以防止监听遗漏。对于 S-CSCF 而言, 别名组技术能够解决号码关联问题, 能够实现对 PUI 1和 PUI 2的同 时监控。
目前 P-CSCF没有号码关联信息, 也没有别名组信息。 在 P-CSCF上实 现一些功能, 如监听功能时, 需要将一个用户的所有号码形式全部进行布 控, 才能有效防止遗漏, 操作麻烦, 实现成本较高。 发明内容
有鉴于此, 本发明实施例提供一种号码关联的实现方法及系统, 能够 基于 P-CSCF实现用户号码的关联。
为达到上述目的, 本发明实施例的技术方案是这样实现的:
