Description

接入网关控制功能实体中用户的业务接入方法与系统 技术领域
本发明涉及接入网关控制功能 ( AGCF , Access Gateway Control Function )实体中用户的业务接入技术,尤其涉及一种固网仿真子系统( PES, PSTN( Public Switched Telephone Network )/ISDN( Integrated Services Digital Network ) Emulation Subsystem )网络中接入网关控制功能实体中用户的业 务接入方法与系统。 背景技术
IP多媒体子系统( IMS , IP Multimedia Core Network Subsystem )是由 第三代合作伙伴计划 ( 3GPP, 3rd Generation Partnership Project )组织提出 的一种基于 IP的网络架构, 其构建了一个开放而灵活的业务环境, 支持多 媒体应用, 并为用户提供丰富的多媒体业务。 而 PES是支持电信和互联网 融合业务及高级网络协议 ( TISPAN , Telecommunications and Internet converged Services and Protocols for Advanced Networking ) 的 , 将传统用户 终端接入 IMS而提出的一种基于 IP的网络架构。
在 PES中, 不提倡 AGCF实体直接与营帐(boss ) 系统连接, 在营帐 系统中为分配 AGCF实体中的用户, 不应由营帐系统通过相关接口直接下 发给 AGCF实体, 并在 AGCF实体中进行存储。 目前在欧洲电信标准化组 织 ( ETSI, European Telecommunications Standards Institute )提出的相关规 范中要求 AGCF实体与注册服务器对用户的配置一致, 但并没有说明该如 何实现。
这就要求 AGCF实体等网络实体中存储公有用户标识( PUI, Public User Identifier ) 即呼叫中使用的 PUI。 也就是说 AGCF 实体中为用户线配置的 PUI, 需要与 PES中的应用服务器(AS, Application Server ), 呼叫会话控 制功能(CSCF, Call Session Control Function )实体、归属用户服务器(HSS, Home Subscriber Server )等网元中的 PUI—致。 这在对 AGCF实体中的用 户支持移动性带来了管理和网络负担, 比如需要将 AGCF实体纳入营帐系 统来进行管理, 这无疑加大了网络侧的处理负担, 而 AGCF实体的分布是 零散的, 且所处的位置都较偏远, 将其纳入营帐系统后不可能像维护 HSS、 CSCF实体或 AS那样便利。 例如, 当 AGCF实体中的用户移机时, 需要在 HSS、 CSCF实体或 AS中进行用户逻辑号码(逻辑 PUI ) 与物理号码(物 理 PUI )对应关系的重新配置, 由于 AGCF实体中的配置信息需与 HSS、 CSCF实体或 AS中的一致, 这样, 将不得不在 AGCF实体中更新相应的配 置信息, 如果是大规模的移机或频繁的移机操作, 维护工作将相当繁杂。 发明内容
有鉴于此, 本发明的主要目的在于提供一种接入网关控制功能实体中 用户的业务接入方法与系统, 仅在 HSS中存储用户逻辑号码与物理号码的 对应关系, AGCF通过用户的注册获取 HSS中的用户逻辑号码与物理号码 的对应关系并存储。

本发明的基本思想是: 在 HSS中存储有 AGCF实体中用户的逻辑号码 与物理号码的对应关系, 而 AGCF实体中的用户通过 AGCF实体进行注册 时, 在注册成功后, HSS 将根据注册用户携带的物理号码信息确定出其对 应的逻辑号码信息, 并通知给该 AGCF实体, 对应的 AGCF实体存储该用 户的物理号码与其逻辑号码的对应关系即可, 在接收到该用户的业务接入 请求时, 直接使用携带该用户的逻辑号码即可实现业务的接入。 由于用户 逻辑号码与物理号码的对应关系存储在 HSS中, 因此, 在用户进行移机等 操作时, 直接修改 HSS中的逻辑号码与物理号码的对应关系即可, 而用户 的 AGCF实体在用户进行注册时即可实现与 HSS的同样配置,不必对 AGCF 实体单独维护, 即可实现对移机的操作, 维护成本极低。
为使本发明的目的、 技术方案和优点更加清楚明白, 以下举实施例并 参照附图, 对本发明进一步详细说明。
本发明中的物理号码(或物理 PUI ) 为与用户线(比如 IP地址与端口 号)对应的号码。 在建网时为 AGCF实体中的用户线一次分配, 该物理号 码能被用户永久使用, 物理号码为用户不可见号码。
本发明中的逻辑号码(或逻辑 PUI )为放号时分配给用户的号码, 也是 用户知道的号码, 用户的业务信息也与逻辑号码(或逻辑 PUI )绑定。 在 HSS的管理下, 能实现物理号码(或物理 PUI )与逻辑号码(或逻辑 PUI ) 的绑定, 物理号码与逻辑号码并不一定相同。 但随着放号的变更, 用户的 移机不改号等业务的实现, 绑定关系也会发生相应的变化。 对于某个用户 线而言, 如果在 HSS中只有物理号码(或物理 PUI ) 而没有逻辑号码(或 逻辑 PUI ), 则表示该用户线还没有分配给任何用户。 在收到该用户线的注 册请求时, HSS直接回复注册失败响应。
本发明中,在 HSS或其它网元中存储物理 PUI和逻辑 PUI的对应关系。 AGCF实体在注册请求中使用物理 PUI。 在呼叫和订阅等流程中, AGCF使 用注册响应返回的 PUI, 即逻辑 PUI。 以下详细说明本发明的技术方案是如 何实现的。
图 1 为本发明接入网关控制功能实体中用户的业务接入方法实施例一 的流程图, 在 HSS中存储有 AGCF实体中用户的逻辑号码与物理号码的对 应关系, 如图 1 所示, 本示例的接入网关控制功能实体中用户的业务接入 方法包括以下步驟:
步驟 101 : AGCF实体接收到用户终端的注册请求消息。 具体的, 用户 通过接入网关 (AG, Access Gateway ) 向 AGCF实体发送注册请求消息, AG将用户的注册请求消息透传给 AGCF实体。这里的注册请求消息可以是 H.248标准中的 Service Change消息, 并携带有用户终端的物理号码信息。
步驟 102: AGCF实体向用户终端返回注册成功响应消息。 这里, 注册 成功响应消息可以是 H.248标准中的 Reply消息。
步驟 103: AGCF实体为该 AGCF实体中的用户向查询呼叫会话控制功 能( I-CSCF, Interrogating Call Session Control Function )实体发送注册请求 消息。 这里, 注册请求消息可以是 3GPP TS24.229中的 Register消息。 消息 中携带的 PUI为用户的物理号码。
步驟 104: 接收到 AGCF实体的注册请求消息后, I-CSCF实体向 HSS 发送位置信息请求消息, 该位置信息请求消息是为了使 HSS对用户线的物 理 PUI的合法性进行判断, 并获取用户在呼叫中使用的服务呼叫会话控制 功能( S-CSCF, Serving Call Session Control Function )实体。具体实现消息, 可以为 3GPP TS29.228/3GPP TS29.229 中的 UAR ( User Authorization Request ) 消息。 在对 PUI进行合法性判断时, 除了完成当前 3GPP规范中 要完成的工作外, 还要判断用户是否有相应的逻辑号码(或逻辑 PUI ), 如 果没有逻辑号码(或逻辑 PUI ), 则应该返回失败响应, 这意味着用户线还 未分配给任何用户, 该用户请求注册的物理号码为不合法用户线, 直接返 回失败响应消息, 整个注册流程结束。 HSS根据 I-CSCF实体发送的位置信 息请求消息中的用户物理号码查找该物理号码是否有分配的对应的逻辑号 码,有逻辑号码时通过步驟 105中的位置信息请求响应消息通知 I-CSCF实 体, 否则也通过步驟 105中的位置信息请求响应消息通知 I-CSCF实体, 当 前流程结束。 需要说明的是, 本步驟中, HSS根据用户的物理号码对应的 逻辑号码信息, 为用户确定该用户业务接入中使用的 S-CSCF实体,在确定 用户的物理号码有对应的逻辑号码时,将所确定的 S-CSCF实体信息一并通 知给 I-CSCF实体。 步驟 105: HSS向 I-CSCF实体反馈位置信息响应消息, 为位置信息请 求响应消息, 这里, 位置信息请求响应消息可以是 3GPP TS29.228/3GPP TS29.229中的 UAA ( User Authorization Answer )消息。 位置信息响应消息 中携带有 S-CSCF实体信息, 由于此次注册尚未对用户进行鉴权,反馈位置 信息响应消息中将不会携带用户的物理号码对应的逻辑号码信息。
步驟 106: I-CSCF实体向用户的 S-CSCF发送注册请求消息。 注册请 求消息可以是 3GPP TS24.229中的 Register消息。
步驟 107: 接收到 I-CSCF实体的注册消息后, S-CSCF实体给 HSS发 送鉴权请求消息,将鉴权中使用的相关信息发给 HSS,以便 HSS进行鉴权。 这里相关信息包括用户终端的硬件的标识信息等信息。 鉴权请求消息可以 是 3GPP TS29.228/3GPP TS29.229 中的 MAR ( Multimedia Authorization Request ) 消息。
步驟 108: HSS向 S-CSCF实体反馈鉴权响应消息, 为鉴权请求的响应 消息。 这里, 鉴权请求的响应消息可以是 3GPP TS29.228/3GPP TS29.229中 的 MAA ( Multimedia Authorization Answer ) 消息。
步驟 109: S-CSCF实体向 I-CSCF实体返回注册失败响应消息。 这里, 注册失败响应消息可以是 3GPP TS24.229中的 401消息等, 该 401消息中 携带有前述的鉴权认证用的随机数。 当用户使用其他注册方式时, 401消息 中携带的可以是其他信息, 401消息也可以是其他失败响应消息。
步驟 110: I-CSCF实体给 AGCF实体返回注册失败响应消息。 这里, 注册失败响应消息可以是 3GPP TS24.229中的 401消息, 该 401消息中携 带有前述的鉴权认证用的随机数。
步驟 111 : 接收到注册失败响应消息后, AGCF实体发起再次注册, 向 I-CSCF实体发送注册请求消息。这里的注册请求消息可以是 3GPP TS24.229 中的 Register消息。 注册请求消息中携带有用户的物理号码信息。 步驟 112: I-CSCF实体向 HSS发送位置信息请求消息, 该位置信息请 在呼叫中使用的 S-CSCF实体。具体实现消息,可以为 3GPP TS29.228/3GPP TS29.229中的 UAR ( User Authorization Request )消息。 在对 PUI进行合法 性判断时, 除了完成当前 3GPP规范中要完成的工作外,还要判断用户是否 有相应的逻辑号码(或逻辑 PUI ), 如果没有逻辑号码(或逻辑 PUI ), 则应 该返回失败响应, 这意味着用户线还未分配给任何用户, 该用户请求注册 的物理号码为不合法用户线, 直接返回失败响应消息, 整个注册流程结束。 HSS根据 I-CSCF实体发送的位置信息请求消息中的用户物理号码查找该物 理号码是否有分配的对应的逻辑号码, 有逻辑号码时通过步驟 113 中的位 置信息请求响应消息通知 I-CSCF实体, 否则也通过步驟 113中的位置信息 请求响应消息通知 I-CSCF实体, 当前流程结束。需要说明的是,本步驟中, HSS根据用户的物理号码对应的逻辑号码信息, 为用户确定该用户业务接 入中使用的 S-CSCF实体,在确定用户的物理号码有对应的逻辑号码时,将 所确定的 S-CSCF实体信息一并通知给 I-CSCF实体。 HSS还需要对 AGCF 实体发送的消息按之前为 AGCF实体确定的随机数进行鉴权认证, 如果鉴 权认证成功, 则通知 I-CSCF实体, 否则注册失败, 当前注册流程结束。
步驟 113: HSS向 I-CSCF实体返回位置信息响应消息, 为位置信息请 求响应消息, 这里的位置信息响应消息可以是 3GPP TS29.228/3GPP TS29.229中的 UAA ( User Authorization Answer )消息。 位置信息响应消息 中携带有用户业务接入时使用的 S-CSCF实体信息。
步驟 114: 接收到位置信息响应消息后, I-CSCF实体向 S-CSCF实体 发送注册请求消息。 这里的注册请求消息可以是 3GPP TS24.229 中的 Register消息。
步驟 115: 接收到注册请求消息后, S-CSCF向 HSS发送业务分配请求 消息, 主要是为获取用户的业务信息。 这里的业务分配请求消息可以是
3GPP TS29.228/3GPP TS29.229中的 SAR( Server Assignment Request )消息。
HSS接收到业务分配请求消息后, 确定用户的签约业务信息, 并将该用户 的签约业务信息通过步驟 116中的业务分配请求的响应消息通知 S-CSCF实 体,同时,将用户的物理号码所对应的逻辑号码信息一并通知 S-CSCF实体, 再由 S-CSCF实体将用户的逻辑号码通知 I-CSCF实体, 以下详细说明之。
步驟 116: HSS向 S-CSCF实体进行业务分配的响应, 即向 S-CSCF实 体发送业务分配请求的响应消息, 由 HSS返回业务信息, 并在业务分配请 求的响应消息中携带用户的逻辑号码。 这里的业务分配请求的响应消息可 以是 3GPP TS29.228/3GPP TS29.229中的 SAA ( Server Assignment Answer ) 消息。 S-CSCF实体存储 HSS返回的业务信息。
步驟 117: S-CSCF实体向 I-CSCF实体返回注册成功响应消息。 这里 的注册成功响应消息可以是 3GPP TS24.229中的 200 OK消息,该消息中携 带有用户的逻辑号码信息。
步驟 118: I-CSCF实体向 AGCF实体返回注册成功响应消息。 这里的 注册成功响应消息可以是 3GPP TS24.229中的 200 OK消息,该消息中携带 有用户的逻辑号码信息。 AGCF 实体保存注册成功响应消息中返回的用户 的逻辑 PUI, 即保存用户的逻辑 PUI与物理号码的对应关系, 将用户的逻 辑号码作为发起呼叫时使用的号码。
本发明通过在 HSS上实现物理号码(或物理 PUI ) 与逻辑号码(或逻 辑 PUI ) 的灵活绑定, 使现有技术中需要 AGCF实体与 HSS中存储的 PUI 必须在任何时候保持一致, 以及如何保持一致的要求不复存在。 同时也能 方便地让 AGCF实体中的用户实现移机不改号等业务。 在上述的注册过程 中,用户的逻辑号码与物理号码的对应关系也可以同时存储于 S-CSCF实体 及 I-CSCF实体中。 在注册过程中用户的业务信息的分配也可以更加灵活, 比如可以不在 CSCF 实体等网元中进行存储。 呼叫过程中, 用户的业务信 息的获取也可以更加灵活, 比如可以在呼叫过程中到 HSS或其它网元上获 取用户的业务信息。
实现注册后, AGCF 实体中的用户, 无论是作被叫还是主叫, 在呼叫 过程中, 都可以使用注册中获取的逻辑号码与 AGCF实体记录的物理号码 (对应终端实体与端口) 的对应关系, 实现正常的呼叫。
图 2 为本发明接入网关控制功能实体中用户的业务接入方法实施例二 的流程图, 在 HSS中存储有 AGCF实体中用户的逻辑号码与物理号码的对 应关系, 如图 2所示, 本示例的接入网关控制功能实体中用户的业务接入 方法包括以下步驟:
步驟 201至步驟 206与前述步驟 101至步驟 106完全相同。
而步驟 207至步驟 210与前述步驟 115至步驟 118完全相同。 图 2所 示的用户注册流程与前述图 1 所示的注册流程所不同的是, 用户注册过程 中没有挑战的情形, 即不需经 HSS对该用户鉴权认证, 通过首次注册即完 成了整个注册流程。 这种情形用于特定用户的情形, 该用户无需鉴权, 例 如优先级较高的用户。
