Description

移动网络获取 IMS控制点信息的方法及系统 技术领域
本发明涉及 IMS ( IP Multimedia Subsystem, IP多媒体子系统), 尤其 涉及一种移动网络获取 ICP ( IMS控制点)信息的方法及系统。 背景技术
IMS是由 3GPP ( 3rd Generation Partnership Project, 第三代合作伙 伴计划)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, 并能够为用户提供丰富的多媒体业务。
在 IMS业务体系中, 控制层和业务层是分离的, 控制层不提供具体 业务, 只向业务层提供必要的触发、 路由和计费等功能。
控制层中业务触发和控制功能是由 CSCF ( Call Session Control Function, 呼叫会话控制功能) 完成的。 CSCF 分为三种类型: P-CSCF ( Proxy-Call Session Control Function , 代理 CSCF ) 、 I-CSCF ( Interrogating-Call Session Control Function, 查询 CSCF ) 和 S-CSCF ( Serving-Call Session Control Function, 服务 CSCF ) ; 其中, S-CSCF 负主要责任, I-CSCF是可选的。 除此之外, IMS业务体系中还有一些辅 助网元, 如 IBCF ( IMS边界控制功能) 和 ATCF (访问转移控制功能 ) 等。
业务层由一系列 AS ( Application Server, 应用服务器)组成, 并提 供具体业务服务。 AS 可以是独立的实体, 也可以存在于 S-CSCF 中。 S-CSCF根据用户的签约信息控制业务触发, 调用 AS上的业务, 实现业 务功能。
会话中的端到端设备称为 UE ( User Equipment , 用户设备) , 负责 与使用者的交互。 有的 UE具有多种接入移动网络的方式, 如通过 3GPP 移动网络的 PS ( Packet Switch, 包交换 )域接入移动网络, 通过非 3GPP 移动网络(如 CDMA (码分多址) IX或 Wimax (全球微波互联接入 ) 网络) 的 PS 域接入移动网络, 甚至可以通过移动网络的 CS ( Circuit Switch, 电路交换) 域接入移动网络。 移动网络包括基站子系统和核心 网, 核心网网元可以是 SGSN (服务 GPRS 支持节点) 、 GGSN (网关 GPRS支持节点) 、 MME (移动管理实体) 、 MSC (移动交换中心) 、 PCF (分组控制功能)或 PDSN (分组数据服务节点)等。 为了实现移动 网络与 IMS网络的交互,在某些情况下需要移动网络获得 ICP信息, ICP 可以是 P-CSCF、 I-CSCF、 IBCF、 ATCF或 AS等具有 IMS信令控制功 能的实体, 甚至可以是具有 IMS信令功能的 MSC。
图 1是现有技术中 MSC获取 ICP信息的流程图, 获取流程包括: 步驟 101 : UE向移动网络发起附着请求, 比如向为自身服务的基站 子系统发送附着请求 ( Attach Request ) 消息; 其中, 基站子系统可以是 基站系统( BSS , Base Station System )或无线网络控制器( RNC , Radio Network Controller ) 。
步驟 102: 基站子系统将附着请求消息发送给 MSC。
步驟 103: MSC收到附着请求消息后, 允许 UE附着并使用移动网 络, 于是向 UE发送允许附着消息, 比如附着接受 (Attach Accept ) 消 息, 该允许附着消息途经基站子系统。
步驟 104: 基站子系统将允许附着消息发送给 UE。
步驟 105: MSC允许 UE附着并使用移动网络后,向 UE的归属 IMS 网络发起注册请求, 比如向 UE的归属 IMS网络中的 S-CSCF发送注册 ( Register ) 消息, 该注册消息属于 IMS信令。
步驟 106: S-CSCF允许 UE接入 IMS网络, 于是向 MSC返回注册 响应, 比如发送 "200 OK" 消息, 该 "200 OK" 消息属于 IMS信令。 步驟 107: UE通过 PS域提供的接入服务和 P-CSCF向 UE的归属
IMS网络发起注册请求,比如向 P-CSCF发送 Register消息,以使用 IMS 网络提供的业务; 其中, Register消息属于 IMS信令。
以下步驟是 ICP不在 AS上的情况。
如果 ICP在 P-CSCF和 S-CSCF之间, 如在 IBCF上, 则包括: 步驟 108a: P-CSCF收到注册请求后, 选择服务该 UE的 ICP, 并将 该注册请求转发给该 ICP。
步驟 109a: ICP收到注册请求后, 向 S-CSCF发送另一注册请求, 该另一注册请求中携带有 ICP信息, 该 ICP信息可以是直接定位 ICP的 信息, 如 ICP的号码、 地址或标识, 也可以是间接定位 ICP的信息, 如
ICP的索引, 还可以是上述各种信息的任意组合。
步驟 110a: S-CSCF允许 UE接入 IMS网络并使用 IMS网络提供的 业务, 于是返回注册响应, 比如发送 "200 OK" 消息, 该 "200 OK" 消 息属于 IMS信令。
步驟 111a: 注册响应到达 ICP, ICP将该注册响应转发给 P-CSCF。 如果 ICP在 P-CSCF上, 则步驟 108a-l l la简化为:
P-CSCF收到注册请求后, 向 S-CSCF发送另一注册请求, 该另一注 册请求中携带有 ICP信息。
S-CSCF允许 UE接入 IMS网络并使用 IMS网络提供的业务, 于是 向 P-CSCF返回注册响应, 比如发送 "200 OK" 消息, 该 "200 OK" 消 息属于 IMS信令。
如果 ICP在 S-CSCF上, 则步驟 108a-l l la简化为:
P-CSCF收到注册请求后, 将该注册请求转发给 S-CSCF。
S-CSCF允许 UE接入 IMS网络并使用 IMS网络提供的业务, 于是 向 P-CSCF返回注册响应, 比如发送 "200 OK" 消息, 该 "200 OK" 消 息属于 IMS信令。
以下步驟是 ICP在 AS上的情况。
步驟 108b: P-CSCF收到注册请求后,将该注册请求转发给 S-CSCF。 步驟 10%: S-CSCF允许 UE接入 IMS网络并使用 IMS网络提供的 业务, 于是向 P-CSCF返回注册响应, 比如发送 "200 OK"消息,该 "200 OK" 消息属于 IMS信令。
步驟 110b: S-CSCF向 ICP转发注册请求。
步驟 111b: ICP收到注册请求后, 向 S-CSCF返回注册响应, 该注 册响应中携带有 ICP信息, 该 ICP信息可以是直接定位 ICP的信息, 如 ICP的号码、 地址或标识, 也可以是间接定位 ICP的信息, 如 ICP的索 引, 还可以是上述各种信息的任意组合。
以下步驟是上述两种情况后续的共同步驟。
步驟 112: P-CSCF收到步驟 11 la或 10%的注册响应后, 向 UE转 发该注册响应。
步驟 113: S-CSCF获得 ICP信息后,将获得的 ICP信息通知给 MSC, 比如向 MSC发送 Notify (通知) 消息, 该 Notify消息中携带有获得的 ICP信息, 且该 Notify消息属于 IMS信令。
由以上流程可以看出, 现有技术中 MSC必须支持 IMS信令并完成 代替 UE的注册过程才能获得 ICP信息; 如果 MSC不支持 IMS信令, 则为了能够应用图 1 所示的流程, 需要增加新的接口与协议以使 MSC 能够与 S-CSCF进行消息交互;且也只定义了 MSC如何获取 ICP信息的 过程, 因此上述流程的应用场景很有限。 发明内容
有鉴于此, 本发明的主要目的在于提供一种移动网络获取 ICP信息的 方法及系统, 使移动网络中各网元都能获得 ICP信息。
为达到上述目的, 本发明的技术方案是这样实现的:

进一步地, 所述第一核心网网元为服务所述 UE的原 MSC; 所述第 二核心网网元为目标 MSC; 发送给目标 MSC的消息为切换请求。
由以上技术方案可以看出, 本发明中, ICP信息是由 IMS网络提供给 UE, 再由 UE提供给移动网络中的基站子系统或核心网网元, 因此根据本 发明, 移动网络中的各网元无需增加新的接口或协议就能获得 ICP信息, 而不限于仅有 MSC能获得 ICP信息。 另外, 本发明中, MSC不通过 IMS 过程获取 ICP信息, 因此本发明中的 MSC可以不支持 IMS信令。 综上, 本发明可以应用于更多的应用场景。 附图说明

图 2为本发明实施例一的移动网络获取 ICP信息的流程图;
图 3为本发明实施例二的移动网络获取 ICP信息的流程图;

本发明移动网络获取 ICP信息的方法主要包括: UE通过 IMS过程 从 IMS信令中获得 ICP信息;
所述 UE将携带有所述 ICP信息的消息发送给所述移动网络中的基 站子系统或第一核心网网元。
这里, IMS过程指 IMS注册过程或其他 IMS消息交互过程。 另夕卜, 本领域技术人员应当理解, IMS过程中交互的各种消息都属于 IMS信令。
以下通过几个实施例对本发明作进一步详细说明。
实施例一
实施例一描述了一种由 IMS网络向 UE提供 ICP信息并由 UE将 ICP 信息提供给移动网络中的核心网网元的方法, 其中 ICP不在 AS上。 如 图 2所示, 该方法包括:
步驟 201: UE通过 PS域向 IMS网络发起注册请求,比如发送 Register 消息。
步驟 202: 注册请求途经 P-CSCF, P-CSCF将注册请求转发给 ICP。 步驟 203: ICP将注册请求转发给 S-CSCF。
步驟 204: S-CSCF允许 UE接入 IMS网络,于是返回第一注册响应, 比如发送 "200 OK" 消息。
步驟 205: ICP收到第一注册响应后,向 P-CSCF发送第二注册响应, 该第二注册响应中携带有 ICP信息, 该 ICP信息可以是直接定位 ICP的 信息, 如 ICP的号码、 地址或标识, 也可以是间接定位 ICP的信息, 如 ICP的索引, 还可以是上述各种信息的任意组合。 步驟 206: P-CSCF收到第二注册响应后,向 UE转发第二注册响应, 该第二注册响应中携带有 ICP信息。
步驟 202-206描述的是 ICP在 P-CSCF和 S-CSCF之间的情况,如果 ICP在 P-CSCF上, 则步驟 202-206简化为:
P-CSCF收到注册请求后, 将注册请求转发给 S-CSCF;
S-CSCF允许 UE接入 IMS网络, 于是返回第一注册响应, 比如发 送 "200 OK" 消息;
P-CSCF收到第一注册响应后, 向 UE发送第二注册响应, 该第二注 册响应中携带有 ICP信息, 该 ICP信息可以是直接定位 ICP的信息, 如 ICP的号码、 地址或标识, 也可以是间接定位 ICP的信息, 如 ICP的索 引, 还可以是上述各种信息的任意组合。
如果 ICP在 S-CSCF上, 则步驟 202-206简化为:
注册请求途经 P-CSCF, P-CSCF将注册请求转发给 S-CSCF;
S-CSCF允许 UE接入 IMS网络, 于是返回注册响应, 该注册响应 中携带有 ICP信息, 该 ICP信息可以是直接定位 ICP的信息, 如 ICP的 号码、 地址或标识, 也可以是间接定位 ICP的信息, 如 ICP的索引, 还 可以是上述各种信息的任意组合;
P-CSCF收到注册响应后, 向 UE转发注册响应, 该注册响应中携带 有 ICP信息。
上述这些步驟属于 IMS注册过程, UE和 IMS网络可能还存在其他
IMS消息交互过程, 比如 UE可向 S-CSCF发送 Subscribe (订阅 )消息, S-CSCF会向 UE发送 Notify消息, Notify消息经过 ICP时, ICP在转发 的 Notify消息中携带 ICP信息, 从而使 UE获得 ICP信息。
步驟 207: UE向移动网络的核心网网元发送消息, 消息经过基站子 系统转发, 但基站子系统不理解消息内容, 在发送的消息中携带有 UE 获得的 ICP信息; 其中,发送的消息可以是发起 CS起呼或执行 CS终呼 过程中向 MSC发送的 Service Request (业务请求 )消息, 也可以是发起 位置更新过程中向 SGSN发送的 Routing Area Update (路由区更新 ) 消 息, 等等。
实施例二
实施例二描述了一种由 IMS网络向 UE提供 ICP信息并由 UE将 ICP 信息提供给移动网络中的核心网网元的方法, 其中 ICP在 AS上。 如图 3所示, 该方法包括:
步驟 301: UE通过 PS域向 IMS网络发起注册请求,比如发送 Register 消息。
步驟 302 : 注册请求途经 P-CSCF , P-CSCF 将注册请求转发给 S-CSCF。
步驟 303 : S-CSCF收到注册请求后, 可以从 HSS ( Home Subscriber Server, 归属用户服务器) 获取 ICP信息。
步驟 304: S-CSCF允许 UE接入 IMS网络, 于是返回注册响应, 比 如发送 "200 OK" 消息, 如果 S-CSCF获取了 ICP信息, 则可以在注册 响应中携带 ICP信息。
可选地, S-CSCF在发送的注册响应中不携带 ICP信息。
步驟 305: P-CSCF收到注册响应后, 向 UE转发注册响应, 该注册 响应中携带有 ICP信息。
如果步驟 304中的注册响应未携带 ICP信息, 则 P-CSCF转发的注 册响应中也不携带 ICP信息。
步驟 306: S-CSCF根据 UE的签约信息向 ICP转发注册请求。
步驟 307: ICP收到注册请求后, 可以更新 HSS上的 ICP信息, 该 ICP信息可以是直接定位 ICP的信息, 如 ICP的号码、 地址或标识, 也 可以是间接定位 ICP的信息, 如 ICP的索引, 还可以是上述各种信息的 任意组合; 之后, HSS通知 S-CSCF更新后的 ICP信息。
步驟 308: ICP向 S-CSCF返回注册响应, 比如发送 "200 OK"消息。 步驟 309: 如果 S-CSCF收到 HSS发来的更新后的 ICP信息, 则向 UE发送 ICP信息已被更新的通知, 比如发送 Notify消息, 该 Notify消 息中携带有更新后的 ICP信息。
步驟 310: Notify消息途经 P-CSCF, P-CSCF将通知消息转发给 UE, 该通知消息中携带有更新后的 ICP信息。
步驟 311 : UE向移动网络的核心网网元发送消息, 消息经过基站子 系统转发, 但基站子系统不理解消息内容, 在发送的消息中携带有 UE 获得的更新后的 ICP信息; 其中, 发送的消息可以是发起 CS起呼或执 行 CS终呼过程中向 MSC发送的 Service Request消息,也可以是发起位 置更新过程中向 SGSN发送的 Routing Area Update消息, 等等。
实施例三
实施例三描述了一种由 IMS网络向 UE提供 ICP信息并由 UE将 ICP 信息提供给移动网络中的基站子系统, 并且基站子系统可以将 ICP信息 提供给移动网络的核心网网元的方法, 其中 ICP不在 AS上。 如图 4所 示, 该方法包括:
步驟 401-406: 与图 2中步驟 201-206相同, 在此不再赘述。
步驟 401-406属于 IMS注册过程, UE和 IMS网络可能还存在其他 消息交互过程, 比如 UE可向 S-CSCF发送 Subscribe消息, S-CSCF会 向 UE发送 Notify消息, Notify消息经过 ICP时, ICP在转发的 Notify 消息中携带 ICP信息, 从而使 UE获得 ICP信息。
步驟 407: UE向基站子系统发送消息, 发送的消息中携带有 UE获 得的 ICP信息;其中,发送的消息可以是 RRC Connection Setup Complete (无线资源控制连接建立完成)消息、 RRC Handover to UTRAN Complete (无线资源控制切换到 UTRAN完成 ) 消息或 RR Assignment Complete (无线资源管理指配完成) 消息等。
步驟 408: 步驟 407之后, UE可能触发业务, 比如发起起呼或执行 终呼过程等。
步驟 409: 基站子系统可以向核心网网元发送消息, 发送的消息中 携带有基站子系统获得的 ICP信息;
基站子系统发送的消息可以是受 UE发送的消息触发, 比如受 UE 发送的 Routing Area Update消息而触发发送的 Initial UE Message (初始 UE消息); 也可以不是受 UE发送的消息触发, 比如基站子系统确定需 或 Handover Required (切换请求) 消息; 又可以是收到核心网网元发送 的 RAB Assignment Request (无线接入承载指配请求 ) 消息, 等等。
如果核心网网元是与基站子系统无直接联系的网元 (如 GGSN ) , 则与基站子系统有直接联系的网元 (如 SGSN ) 可以将获得的 ICP信息 通过信令消息告知与基站子系统无直接联系的网元, 比如通过携带有 ICP信息的资源分配 ( Resource Allocation ) 消息。
如果 ICP在 AS上,则步驟 401-406可替换为图 3中的步驟 301-310。 实施例四
实施例四描述了一种由 IMS网络向 UE提供 ICP信息并由 UE将 ICP 信息提供给原 MSC, 再由原 MSC提供给目标 MSC的方法, 其中 ICP 不在 AS上。 如图 5所示, 该方法包括:
步驟 501-506: 与图 2中步驟 201-206相同, 在此不再赘述。
步驟 501-506属于 IMS注册过程, UE和 IMS网络可能还存在其他 消息交互过程, 比如 UE可向 S-CSCF发送 Subscribe消息, S-CSCF会 向 UE发送 Notify消息, Notify消息经过 ICP时, ICP在转发的 Notify 消息中携带 ICP信息, 从而使 UE获得 ICP信息。
步驟 507: UE向原 MSC发送消息, 发送的消息中携带有基站子系 统获得的 ICP信息; 其中, 发送的消息可以是发起 CS起呼或执行 CS 终呼过程中向 MSC发送的 Service Request消息, 也可以是发起位置更 新过程中向 MSC发送的 Location Area Update (位置区更新 ) 消息。
所述原 MSC是指切换发生前服务 UE的原 MSC。
步驟 508: 基站子系统确定需要触发 UE的切换过程时, 向原 MSC 发送 Relocation Required消息或 Handover Required消息 , 消息中携带有 目标标识, 该目标标识可用于定位目标 MSC。
这里, 原 MSC与基站子系统有直接联系。
步驟 509: 根据收到的目标标识, 原 MSC定位目标 MSC并向目标 MSC 发送携带有原 MSC 获得的 ICP 信息的切换请求, 比如发送 MAP-PREPARE-HANDOVER Request (移动应用协议准备切换请求)消 息。
这里, 目标 MSC可以与某些基站子系统有直接联系, 但与步驟 508 中的基站子系统无直接联系。
如果 ICP在 AS上,则步驟 501-506可替换为图 3中的步驟 301-310。 步驟 507也可替换为与图 4中的步驟 407和 409, 即由 UE将获得 的 ICP信息通过信令消息告知基站子系统, 再由基站子系统在确定需要 触发 UE 的切换过程时通过切换请求 (如 Relocation Required 消息或 Handover Required消息) 将获得的 ICP发送给原 MSC。
为实现上述方法, 本发明实施例还提供一种移动网络获取 ICP信息 的系统。 如图 6所示, 该系统包括: UE和基站子系统; 其中,
