技术领域
本发明涉及移动通信领域, 尤其涉及群组用户注册方法、用户状态更新方 法、 用户状态处理装置、 IMS网络实体和通信系统。
背景技术
互联网协议多媒体子系统( Internet Protocol Multimedia Subsystem , 简称 IMS )是第三代移动通信标准化伙伴项目 ( 3rd Generation Partnership Project, 简称 3GPP )标准定义的支持 IP多媒体业务的子系统,其核心特点是采用会话 初始协议 ( Session Initiation Protocol, 简称 SIP )和接入的无关性。 IMS是一 个在分组域上的多媒体控制 /呼叫控制平台, 支持会话类和非会话类多媒体业 务, 为未来的多媒体应用提供了一个通用的业务平台。
在 IMS网络中, 呼叫^舌控制功能( Call Session Control Function, 简称 CSCF ) 实体是 IMS的核心功能实体, 主要用于实现 IMS的呼叫和会话控制。 IMS中定义了三种 CSCF实体: 代理 CSCF ( Proxy CSCF, 简称 P-CSCF )、 问 询 CSCF ( Interrogating CSCF, 简称 I-CSCF )和服务 CSCF ( Service CSCF, 简称 S-CSCF ); 其中 S-CSCF的主要功能是接受用户注册, 从归属用户服务器 ( Home Subscriber Server, 简称 HSS )下载并临时存储用户相关数据; 重定向 路由,进行呼叫^舌控制;触发用户签约业务,协同业务平台进行业务支持等。 IMS中的 HSS实体则主要负责存储用户签约信息和位置信息等。
IMS 网络中的注册过程使用户设备 ( User Equipment, 简称 UE )可以使 用 IMS服务, 但是 SIP只允许单用户的注册, 即一条注册请求只能注册一个 公共用户身份, 如果要注册多个公共用户身份, 则需要重复注册多次, 这样会 耗费大量的无线资源。 为此 3GPP提供了隐式注册机制, 由预先定义好的共用 一个私有用户身份的一组公共用户组成一个隐式注册集合,当集合中任一公共 用户被注册或注销时 , 隐式注册集合中的所有公共用户均都被注册或注销。
隐式注册机制可以实现通过单条注册请求注册集合中所有公共用户,解决 了单用户注册机制中由于重复注册所产生的资源耗费的问题。
然而, 发明人在实现本发明过程中发现, 隐式注册机制也存在以下缺陷: 一是在实际应用中, 隐式注册集合中所有公共用户状态并不总是完全一致,可 能存在一些用户处于可服务状态, 而另一些用户处于不可服务状态(例如 UE 关机、 故障等)的情况, 当处于可服务状态的公共用户发起注册请求后, 集合 中所有公共用户即均被注册,而事实是处于不可服务状态的公共用户无法接受 服务, 因而并不需要被注册。 此外, 在注册成功后, 当隐式注册集合中某一公 共用户的状态发生变化时, IMS 网络无法对该公共用户的状态进行相应的更 改,在发生如用户设备发生故障等情况时, 由于注销该用户会导致整个隐式注 册集全部被注销, 因此 IMS 网络无法单独注销隐式注册集合中的某一用户。 由于 IMS网络是按照用户的注册信息处理业务,只要用户处于注册状态, IMS 就会处理与该用户有关的业务, 因此上述两种情况均可能产生资源的浪费。此 夕卜, IMS网络不能对公共用户的状态进行更改还会导致一些业务(如存在业务) 提供错误的用户状态信息等问题。
发明内容
本发明提供一种群组用户注册方法、用户状态处理装置、 IMS网络实体和 通信系统, 能够对符合条件的动态群组用户进行注册。
本发明还提供一种用户状态更新方法和通信系统,能够实现在完成动态群 组用户注册后, 当动态群组中用户状态发生变化时, 将所述变化通知 IMS 网 络对该用户的状态做出相应的更新。
本发明的一个技术方案提供一种群组用户注册方法, 包括: 对隐式注册集 合中的用户标识进行注册;以及对所述隐式注册集合中的相关用户信息进行更 新。
本发明的一个技术方案提供一种用户状态更新方法, 包括: 对动态群组中 的用户标识进行注册; 所述动态群组中的用户标识的状态发生改变时,根据状 态改变信息对隐式注册集合中的相关用户信息进行相应的更新。
本发明的一个技术方案提供一种用户状态处理装置, 包括: 用户状态获取 单元, 用于获取动态群组中用户标识的当前状态; 存储单元, 用于保存所述动 态群组中用户标识的状态信息; 控制单元, 用于根据所述存储单元所保存的用 户标识的状态信息和所述用户状态获取单元所获取的用户标识的当前状态控 制发送单元发送更新请求, 以对隐式注册集合进行更新。
本发明的一个技术方案提供一种 IMS 网络实体, 包括: 接收单元, 用于 接收表示对隐式注册集合进行更新的更新请求; 更新单元, 用于根据所述接收 单元接收的更新请求对所述隐式注册集合中的相关用户信息进行更新。
本发明的一个技术方案提供一种通信系统, 包括用户设备、用户状态处理 装置和 IMS 网络实体; 用户状态处理装置, 用于感知用户设备的状态, 并根 据所感知的用户设备的状态和已保存的用户设备的状态信息向 IMS 网络实体 发送更新请求; IMS网络实体,用于根据所述用户状态处理装置发送的更新请 求对隐式注册集合中的相关用户信息进行更新。
本发明的一个技术方案提供一种用户状态更新方法, 包括: 订阅用户的注 册状态信息; 接收状态发生变化的用户标识及变化后的注册状态信息。
本发明的一个技术方案提供一种通信系统,包括多用户管理控制实体和属 于 IMS 网络的用户注册状态订阅单元, 其中: 所述多用户管理控制实体, 用 于接受所述用户注册状态订阅单元对注册状态信息的订阅,在所管理的用户标 识的状态发生变化时,向所述用户注册状态订阅单元发送状态发生变化的用户 标识及其当前注册状态信息; 所述用户注册状态订阅单元, 用于向多用户管理 控制实体订阅用户注册状态信息 ,接收多用户管理控制实体所提供的状态发生 变化的用户标识及其当前注册状态信息。
从以上的一个技术方案可以看出,由于在注册完成前或完成后要对所述隐 式注册集合进行更新, 因此可以实现仅仅注册符合一定条件的动态群组用户。 而在现有技术中, 即使某些用户不符合注册条件,也要对隐式注册集合中所有 的用户都进行注册。对比可知, 采用本发明的群组用户注册方案可以在一定程 度上避免资源的浪费。
从以上另一个技术方案可以看出,在注册之后, 当动态群组中的公共用户 标识的状态发生改变时,可以根据状态改变信息对隐式注册集合中的相关用户 信息进行相应的更新, 从而避免了由于无法更新所导致的资源浪费的问题。
另外, 通过订阅用户的注册状态信息; 使当用户标识的状态发生变化时, 可以获知状态发生变化的用户标识及变化后的注册状态信息,进而, 能够实现 对与该用户标识关联的用户信息数据进行修改, 实现了在用户状态发生变化 时, 可以通知 IMS 网络对该用户状态做出相应的更新, 避免了由于无法更新 所导致的资源浪费的问题。

对隐式注册集合中的相关用户信息的更新可以是根据多用户管理控制实 体发起的更新请求进行,或者根据多用户管理控制实体通过至少一个用户状态 处理单元发起的更新请求而进行, 或者根据用户终端发起的更新请求而进行。 多用户管理控制实体发送更新请求可以通过维护接口管理方式,或者消息 通知方式。通过维护接口管理方式发送更新请求主要是以主动发起命令的方式 通过 Diameter消息、 会话初始化协议( SIP )、 简单网络管理协议( SNMP )、 超文本传输协议(HTTP )、 无线会话协议(WSP )、 对象交换协议(OBEX ) 或同步标识语言( SyncML )或者其他各种私有协议、 内部协议发送更新请求。 通过消息通知方式发送更新请求主要是根据 IMS 网络实体的订阅以类似短消 息等的通知方式发送更新请求, 具体实现时, 可以采用 SIP通知消息进行, 此 时, 所述 SIP通知消息中携带有表示更新请求的注册信息事件包。
用户终端发起更新请求可以是具体的注销或注册请求,所述请求中携带状 态发生变化的公共用户标识以及表示对该标识进行注册或注销的标识符。
对隐式注册集合中的相关用户信息进行更新可以是在所述注册完成前或 完成后对隐式注册集合中的用户标识进行更新,使该集合中仅包括符合预定条 件的用户标识,还可以是对隐式注册集合中用户标识的注册状态进行更新,对 不符合预定条件的用户标识,将相应隐式注册集合中该用户标识的状态更新为 不可服务状态。
在上述方法中, 所述的多用户管理控制实体可以是企业网的基于 IP技术 的专用电话交换机 ( IP private branch ( telephone ) exchange, 简称 IP PBX )或 基于 IMS的公众交换电话网 /综合业务数字网仿真子系统中的接入网关控制功 能( Access Gateway Control Function, 简称 AGCF )实体。 下面以 AGCF为例 进行伴细描述

当多用户管理控制实体中未存储当前隐式注册集合所包含的公共用户标 识时, 需要先从 HSS、 设备管理 /客户端供应 (DM/ CP )服务器或网络管理实 体等下载所述信息。
图 2是 P1中所述隐式注册过程的一个实施例, 包括以下步骤:
B1至 B2、 多用户管理控制实体代理 UE通过 P-CSCF向 I-CSCF发送携 带 IMS公共用户标识( IMPU )、 私有用户标识( IMPI )及联系地址的注册请 求。

下面给出 C1中所述 H.248的注册过程的一个具体实例:
D1、媒体网关( Media Gateway, 简称 MG )向 AGCF发送关于 ROOT (表 示媒体网关)的服务改变方法(ServiceChangeMethod )为重启(Restart )的服 务改变( servicechange )命令, 若 MG下存在处于 OutOfService用户 , 则在服 务改变命令中携带服务改变未完成标记( ServiceChangelncompleteFlag ), 否则 不携带;
D2、 AGCF设置所有公共用户标识的状态为 InService, 并向 MG返回响 应 ( Reply ) 消 息 ; 若接 收 的 servicechange 命令 中 携 带 有 ServiceChangelncompleteFlag标记, 则继续 D3; 否则 H.248的注册过程结束。
D3、 MG向 AGCF上报当前状态为 OutOfService的公共用户标识, 上报 完该标识的状态后,还存在未上报的处于 OutOfService的公共用户标识,则继 续携带 ServiceChangelncompleteFlag标记 , 否则不携带。
D4、 AGCF设置上 的公共用户标识的状态为 OutOfService, AGCF 向 MG返回 Reply响应消息 , 若命令中携带 ServiceChangelncompleteFlag标记 , 则等待 MG继续上报, 继续执行上述 D3, 否则 H.248的注册过程结束, 可以 执行其他操作, 如接入呼叫等。
所述的 H.248注册过程还可以是 MG直接上 处于 InService状态的公共 用户标识, 当 AGCF收到 MG上报的第一个处于 InService状态的公共用户标 识后, 直接执行上述群组用户注册过程中的 C2。

从以上的实施例可以看出,由于在注册完成前或完成后要对所述隐式注册 集合进行更新,使该集合中仅包括符合预定条件的公共用户标识,或者将隐式 实现仅仅注册符合一定条件的动态群组用户。
此外 , 由于注册时采取先通过单条消息对动态群组的所有用户进行注册, 再从隐式注册集合中取消不符合条件的公共用户标识,或者先使隐式注册集合 中仅包括符合条件的公共用户标识,再通过单条消息对符合条件的公共用户标 识进行注册, 而不用针对每个用户分别发送消息进行注册, 因而可以实现以较 小资源对符合条件的动态群组用户进行注册。
在注册之后, 当动态群组中的公共用户标识的状态发生改变时, 将符合预 定条件的公共用户标识加入隐式注册集合或在隐式注册集合中将该用户标识 的状态修改为可服务状态,将不符合预定条件的公共用户标识从隐式注册集合 中删除或在隐式注册集合中将该用户标识的状态修改为不可服务状态 ,则能够 实现在公共用户标识的状态发生变化时, 通知 IMS网络, 使 IMS网络可以对 该用户做出相应的处理, 从而避免了由于无法更新所导致的资源浪费的问题。
另外,通过向多用户管理控制实体订阅用户的注册状态信息; 使多用户管 理控制实体在所管理的公共用户标识的状态发生变化时,向用户注册状态订阅 单元发送携带有状态发生变化的公共用户标识及变化后的注册状态信息的注 册状态通知, 因而用户注册状态订阅单元能够通知 HSS对与该公共用户标识 关联的用户信息数据进行修改, 实现了在用户状态发生变化时,可以通知 IMS 网络对该用户状态做出相应的更新,避免了由于无法更新所导致的资源浪费的 问题。
