Description

一种呼叫处理方法及系统
技术领域
本发明属于通信领域, 尤其涉及一种呼叫处理的方法及系统。 背景技术
目前 3G ( Third Generation )技术逐渐成熟、 并已在全 艮多国家、 地区 投入了商用。 IP多媒体子系统( Internet protocol Multimedia Subsystem, IMS ) 的提出为移动网络的多媒体业务提供了一种解决方案。 3G网络被划分成不同 的域, 包括电路交换域(Circuit Switched Domain, CS )、 分组交换域( Packet Switched Domain, PS ) 以及 IMS域。 CS域采用电路交换技术提供语音和多 媒体服务, 与 2G系统比较类似; PS域为用户接入 Internet提供 IP连通性; IMS域采用会话起始协议( Session Initiation Protocol, SIP )作为主要的通信 协议为用户提供基于 IP的多媒体服务。 在 3G 网络中用户终端可以通过 CS 域或 PS 域分别接入网絡, 在通话过程中允许用户在不同网络域之间进行切 换, 而正在进行的会话不会中断。 例如用户正在使用 CS 域通话, 但是当前 CS域的信号已经比较弱, 而 IMS域的信号比较强, 这时最好把话路切换到 IMS 域中, 从而获得更好的通话质量。 3GPP ( Third Generation Partnership Projects )组织正在积极制定 CS域和 IMS域之间切换语音不间断性控制的业 务规范和需求,目前 3GPP-R7版本中正在对 IMS域控制的呼叫不间断性切换 方案作进一步的分析研究。 在该方案中为了后续话音切换做预先的准备, 要 求 CS域的呼叫必须经过 IMS域的语音呼叫连续性 ( Voice Call Continuity, VCC )应用服务器, 具体实现流程如图 1 , 详述如下:
1.支持 VCC的用户通过用户终端( User Equipment, UE )向被叫 B发起 呼叫;
2.拜访移动业务交换中心( Visit Mobile service Switching Center, VMSC ) 检测到相关触发器, 并发送启动检出点 ( Initial detection point, IDP ) 消息到 全球移动通信系统业务控制功能实体 ( Global System Mobile Service Control Function, GSMSCF );
3. GSMSCF检测到该呼叫支持 VCC, 就把呼叫重定向到 IMS域(IMS anchoring determination );
4. GSMSCF分配一个 IP多媒体路由号码( IP Multimedia Routing Number, IMRN ), 并用 Connect指示 MSC把呼叫接续到 IMS域;
5. MSC 根据 IMRN 号码向媒体网关控制功能实体 (Media Gateway Control Function, MGCF )发送初始地址消息( Initial Address Message , IAM );
6. MGCF发送 SIP Invite 消息给呼叫会话控制功能实体(Call Session
Control Function, CSCF );
7. CSCF把呼叫触发到呼叫连续性控制功能实体( Call Continuity Control Function, CCCF );
8. CCCF再向被叫 B发起呼叫请求。
可以看出, 上述为 VCC切换做准备工作而将 CS域发起的呼叫均接续到
IMS域的 VCC应用服务器的接续过程比较复杂,造成用户的呼叫接续耗时较 长, 而且, 并不是用户发起的每一次呼叫均需要进行 VCC切换。 所以目前将 其所有呼叫都接续到 IMS域的 VCC应用服务器势必给用户的使用造成不便 及负面体验影响。 发明内容
本发明实施例的目的在于提供一种呼叫处理方法, 旨在解决现有技术中 存在的不能让用户自主选择其呼叫是否需要进行 VCC处理,而将其所有呼叫 都接续到 IMS域的 VCC应用服务器造成用户的呼叫接续耗时较长以及负面 体验影响的问题。
本发明实施例的另一目的在于提供一种呼叫处理系统, 旨在解决现有技 术中存在的不能让用户自主选择其呼叫是否需要进行 VCC处理,而将其所有 呼叫都接续到 IMS域的 VCC应用服务器造成用户的呼叫接续耗时较长以及 负面体验影响的问题。
本发明实施例是这样实现的, 一种呼叫处理方法, 所述呼叫从通信网络 的第一域发起, 所述方法包括:
收集用户对语音呼叫连续性配置信息并保存;
当接收到用户终端从所述第一域发起的呼叫时, 根据用户标识读取所述 配置信息;
根据配置信息判断是否将呼叫接续到所述第二域, 并进行相应的接续处 理。
一种呼叫处理系统, 所述呼叫从通信网络的电路域发起, 所述系统包括 全球移动通信系统业务控制功能实体、 移动业务交换中心以及语音呼叫连续 性应用服务器, 所述语音呼叫连续性应用服务器包括:
配置信息管理模块, 用于保存用户通过所述电路域或所述 IP多媒体子系 统域提交的语音呼叫连续性配置信息;
所述全球移动通信系统业务控制功能实体包括;
语音呼叫连续性处理模块, 用于根据在电路域发起呼叫的用户标识向所 述配置信息管理模块请求配置信息, 根据配置信息判断是否将呼叫接续到 IP 多媒体子系统域, 并指示移动业务交换中心进行相应的接续处理。
本发明实施例通过 CS 域或 IMS 域预先配置 VCC 相关信息, 以便
GSMSCF在后续的呼叫处理过程中根据这些信息进行相关的处理。 使得用户 可以自主选择有些呼叫是否需要 VCC处理, 如果不需要 VCC处理, 可以实 现用户呼叫的更快接续, 避免用户长时间等待, 提高了用户的满意度。 附图说明
图 1是现有技术 3GPP协议中呼叫处理方法的实现流程图; 图 2是本发明实施例提供的系统组网示意图;
图 3是本发明实施例提供的呼叫处理方法的实现流程图;
图 4是本发明一优选实施例提供的呼叫处理方法的实现流程图。 具体实施方式
为了使本发明的目的、 技术方案及优点更加清楚明白, 以下结合附图及 实施例, 对本发明进行进一步详细说明。 应当理解, 此处所描述的具体实施 例仅仅用以解释本发明, 并不用于限定本发明。
本发明实施例通过 CS 域或 IMS 域预先配置 VCC 相关信息, 以便 GSMSCF在后续的呼叫处理过程中根据这些信息进行相关的处理, 使得用户 可以自主选择有些呼叫是否需要 VCC处理, 如果不需要 VCC处理, 可以实 现用户呼叫的更快接续。
图 2 示出了本发明实施例提供的系统组网示意, 用户终端可以通过 CS 域或 PS 域分别接入网络, 在通话过程中允许用户在不同网络域之间进行切 换, 同时正在进行的会话不会中断。 例如用户开始时注册到 IMS域中, 然后 发起呼叫, CSCF触发 VCC业务, 完成呼叫的接续控制过程, 并进入通话状 态。 由于用户或网络的原因, 用户终端注册到网络的 CS域中, 向 VCC应用 服务器发起呼叫切换请求, 并建立终端到 MSC和 MGW之间的话路链接,在 VCC应用服务器的控制之下, 完成 CS域话路切换原先的 IMS话路, VCC应 用服务器指示释放 IMS话路, 最终实现通话由 IMS域切换到 CS域过程。 其 中, GSMSCF包括配置信息收集模块 101以及 VCC处理模块 102, VCC应 用服务器包括配置信息管理模块 201。配置信息收集模块 101收集用户的 VCC 配置信息, 并提交到 VCC应用服务器的配置信息管理模块 201 中; VCC配 置信息可以包括: 主 /被叫号码、 号码特征(例如号段)或者需要切换的时间 段等。
在本发明一实施例中, 配置信息收集模块 101中有一段业务管理逻辑通 过指示 cs域的智能设备向用户放音来收集用户的 VCC配置信息。 例如, 当 用户拨打管理流程后 GSMSCF把呼叫连接到智能设备, 并指示智能设备放音 提示用户选择功能。 智能设备放音提示用户配置信息的一个示例如下:
1、 默认配置
Figure imgf000007_0001
2、 具体配置
Figure imgf000007_0002
用户在拨打管理流程后, 可以在智能设备放音过程中选择上述 1或 2选 项修改相关的配置。 假设用户选择 2, 还可以进一步选择查询 (选择 1 )、 增 加 (选择 2 )、 修改(选择 3 )或删除(选择 4 )等操作。 当收集完用户的配 置信息后配置信息收集模块 101把配置信息发送到 VCC应用服务器的配置信 息管理模块 201中。
在本发明另一实施例中, 由于 IMS域中使用 SIP协议, 用户可以直接通 过 IMS域与 VCC应用服务器交互实现对 VCC进行配置, 例如通过客户端的 维护界面或者命令直接和 VCC应用服务器进行交互, 将相应地配置信息(例 如: 用户的 VCC配置信息以及用户的 IMS标识和 CS标识的对应关系等)存 储于 VCC应用服务器的配置信息管理模块 201中。
通过上述 VCC配置, 当该用户在 CS域发起呼叫时, GSMSCF的 VCC 处理模块 102根据用户标识向配置信息管理模块 201请求配置信息, 例如当 用户发起对 "7654321" 的呼叫时, MSC接收到呼叫请求后触发 GSMSCF业 务, VCC处理模块 102向配置信息管理模块 201请求 VCC相关配置信息, 请求消息中包含用户 ID22222222222以及被叫号码 7654321 , 配置信息管理 模块 201通过匹配相关的配置信息返回 VCC标识给 VCC处理模块 102。 VCC 处理模块 102根据 VCC标识判断该次呼叫是否支持 VCC处理,例如,当 VCC 标识为 1 , 表示该次呼叫支持 VCC处理, VCC处理模块 102指示 MSC把呼 叫连接到 IMS域中;为 0表示该次呼叫不支持 VCC处理, VCC处理模块 102 指示 MSC进行正常的业务处理。
具体的实现流程如图 3所示, 详述如下:
1. UE发起呼叫;
2. MSC检测到呼叫后, 发送 Initial DP到 GSMSCF触发业务;
3. GSMSCF向 VCC应用服务器请求 VCC配置信息;
4. VCC应用服务器根据请求消息中携带的信息返回对应的 VCC标识;
5. GSMSCF根据返回的 VCC标识分析该次呼叫是否支持 VCC处理,如 果是 , GSMSCF就发送 Connect请求 MSC把呼叫接续到 IMS域,否则 GSMSCF 发送 Continue请求 MSC进行正常的接续处理。
上述以 VCC配置信息为主叫号码和被叫号码进行举例,同样的,当 VCC 配置信息为号码特征或时间段时, 则表示需要对被叫号码符合该号码特征或 用户在该时间段发起的呼叫进行相应的 VCC处理。 有关后续的 MSC将呼叫 连接到 IMS域的处理过程可以参考现有 3GPP相关规范, 不再赘述。
在本发明另一实施例中, 根据附加在被叫号码上的一个特殊的前缀或后 缀判断该次呼叫是否要求进行 VCC处理, 例如, 指定 333为要求进行 VCC 处理的特殊前缀, 则当用户发起呼叫的被叫号码为 3337654321时, 对该呼叫 进行 VCC处理。 相应的 GSMSCF的 VCC处理模块 102进一步包括一前缀 / 后缀提取单元 1021用于根据提取到的该前缀或后缀指示 MSC进行相应的接 续处理。
在本发明一优选实施例中, 既通过分析被叫号码的前缀或后缀判断用户 的呼叫是否要求进行 VCC处理, 也通过 CS域或 IMS域预先配置的 VCC相 关信息判断用户的呼叫是否要求进行 VCC处理, 具体的呼叫处理流程如图 4 所示, 详述如下:
在步骤 S401中, 当用户终端在 CS域发起呼叫时, GSMSCF分析被叫号 码的前缀或后缀判断该次呼叫是否支持 VCC处理, 是则执行步骤 S406, 否 则执行步骤 S402;
在步驟 S402中, GSMSCF向 VCC应用服务器请求 VCC配置信息; 在步骤 S403中, VCC应用服务器根据请求消息中携带的信息返回对应 的 VCC标识;
在步驟 S404中, 根据 VCC标识判断该次呼叫是否支持 VCC处理, 是 则执行步骤 S406, 否则执行步骤 S405;
在步骤 S405中, GSMSCF请求 MSC按照正常的呼叫接续控制过程处理; 在步骤 S406中, GSMSCF请求 MSC把当前呼叫接续到 IMS域。
上述既通过分析被叫号码的前缀或后缀判断用户的呼叫是否要求进行 VCC处理, 也通过 CS域或 IMS域预先配置的 VCC相关信息判断用户的呼 叫是否要求进行 VCC处理的呼叫处理流程更加灵活,使得用户自主选择其呼 叫是否需要进行 VCC处理的方式不再单一。
本发明实施例通过 CS 域或 IMS 域预先配置 VCC 相关信息, 以便 GSMSCF在后续的呼叫处理过程中根据这些信息进行相关的处理。 使得用户 可以自主选择有些呼叫是否需要 VCC处理, 如果不需要 VCC处理, 可以实 现用户呼叫的更快接续, 避免用户长时间等待, 提高了用户的满意度。 另外 还可以临时通过增加前缀或后缀等机制指示 GSMSCF当次呼叫是否需要进行 VCC处理, 使得用户自主选择其呼叫是否需要进行 VCC处理的方式不再单 以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在本 发明的精神和原则之内所作的任何修改、 等同替换和改进等, 均应包含在本 发明的保护范围之内。
