Description

IMS、IMS中的业务开通方法及装置 技术领域
本发明涉及通信领域，尤其是涉及一种互联网协议多媒体子系统(Internet Protocol Multimedia Subsystem，简称为IMS)，IMS中的业务开通方法及装置。
背景技术
IMS是未来多媒体通信的发展方向，也是下一代网络最为重要的组成部分。它是第三代合作伙伴计划(Third Generation Partnership Project，简称为3GPP)提出的支持IP多媒体业务的子系统，其显著特征是采用了会话初始协议(Session Initial Protocol，简称为SIP)体系，通信与接入方式无关，具备多种多媒体业务的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是一种全新的多媒体业务形式，能够满足用户更新颖、更多样化的多媒体业务需求。目前，IMS被认为是下一代网络的核心技术，也是解决移动与固网融合，引入语音、数据、视频三重融合等差异化业务的重要方式。
用户在使用IMS业务之前，需要进行IMS业务的开通，在现有的IMS业务开通技术中，需要涉及多个网元，如图1所示，包括用户归属服务器(Home Subscriber Server，简称为HSS)、签约位置功能(Subscription Locator Function，简称为SLF)、电话号码映射服务器(Telephone Number Mapping，简称为ENUM)和应用服务器(Application Server，简称为AS)等多个网元以及业务支撑系统(如Business and Operation Support System，简称为BOSS)等。
以用户开通由多媒体电话业务应用服务器(Multimedia Telephony Application Server，简称为MMTel AS)提供的语音业务为例，如图2所示，为基于图1所示结构示意图的IMS业务开通流程示意图，包括以下步骤：
步骤101：当用户发起开通MMTel语音业务的业务开通请求时，业务支撑系统需在HSS为该用户配置开通MMTel语音业务所需的用户数据。
通俗地说，本步骤101即为用户在HSS中的开户过程。
所述用户数据包括：IP多媒体公共标识(IP Multimedia Public Identity，简称为IMPU)、IP多媒体私有标识(IP Multimedia Private Identity，简称为IMPI)、鉴权密码、IMS口令、IMS核心网密码和初始化过滤规则(Initial Filter Condition，简称为IFC)等。
当HSS为用户配置用户数据后，用户只能注册到IMS，并不能使用IMS的MMTel语音业务。
步骤102：业务支撑系统在ENUM中为该用户开通电话统一资源标识(TEL Uniform Resource Identifier，简称为TEL URI)和会话开始协议统一资源标识(Session Initiation Protocol URI，简称为SIP URI)的映射关系。
所述TEL URI和SIP URI的映射关系用以支撑该用户作为被叫时，在核心网的路由能力。
步骤103：业务支撑系统将为该用户配置的用户数据与该用户的用户标识绑定在MMTel AS中，完成MMTel语音业务的激活。
此时多媒体电话(Multimedia Telephony，简称为MMTel)语音业务所需要的用户数据已写入MMTel语音业务开通所涉及的各关键网元中，用户能够登陆IMS，使用相应的MMTel语音业务。此后，MMTel AS可将业务开通成功消息返回给业务支撑系统，并由业务支撑系统向所述用户发送短信以进行二次确认，至此，用户完成MMTel语音业务的开通。
在现有IMS业务开通过程中，用户需通过业务支撑系统申请开通IMS业务，业务支撑系统在接收到用户的IMS业务开通请求后，为该用户生成相应的IMPI、IMPU、IFC等用户数据，并将其写入HSS中，此后还需完成ENUM和AS的开通，上述任何一个环节出现错误，某个网元失效，或者业务支撑系统遇到突发性订购导致业务量突然增大时，都会造成IMS业务开通失败或延迟。另一方面，现有的IMS业务开通系统需要在多个网元上均存储用户或业务数据，造成业务或用户数据过于分散，不利于业务的扩展。
针对相关技术中的上述技术问题，目前尚无有效地解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
针对现有IMS业务开通流程中，开通网元多，开通效率低，开通系统复杂，容易发生故障的缺点，本发明提出了一种方法，通过将业务数据开通集中到单一网元，由该新赠网元(即开通事务管理实体)对复杂的开通进行综合管理及事务管理控制；并且规定开通流程的数据格式，提高了IMS业务开通流程的效率，可扩展性，以及IMS业务开通系统的可靠性。
实施例1
图3为根据本发明实施例的IMS中的业务开通方法的流程图。该方法通过在IMS中设置开通事务管理实体实现，该开通事务管理实体存储有IMS中各个网元在开通指定IMS业务过程中所需要的开通信息，如图3所示，该方法包括以下处理步骤S302-S304：
步骤S302，在指定IMS业务的开通过程中，向开通事务管理实体发送查询请求；
步骤S304，接收开通事务管理实体根据查询请求反馈的开通信息。
通过上述各个处理步骤，由于将业务开通所需要的信息均存储在新增的开通事务管理实体中，该开通事务管理功能(Operating Transaction Manager)对复杂的开通进行综合管理及事务管理控制。这样IMS中在业务开通时所涉及的各个网元从该开通事务管理实体中获取业务开通所需要的信息，从而可以解决了现有的IMS业务开通过程涉及到的网元较多导致开通效率低、可靠性差、不利于业务扩展等技术问题，进而提高IMS网络的性能。
需要说明的是，上述指定业务可以包括全部IMS业务中的一个或多个或所有IMS业务。上述步骤的执行主体可以为在IMS业务开通过程中所涉及到的网元，例如AS、S-CSCF、HSS等。
在步骤S304之前，需要IMS中的业务支撑系统将各个网元所需要的信息(即开通信息)开通到上述开通事务管理实体，即通过MS的业务支撑系统将除上述开通事务管理实体之外的其它网元所需要的信息存储至上述开通事务管理实体。
并且，针对相关技术中存在数据一致性问题，衍生垃圾数据，甚至影响系统可靠性、正确性，开通事务管理实体可以与上述各个网元协商确定上述开通IMS业务所需要的信息的格式，以使得开通事务管理实体中存储的开通信息与各个网元在开通IMS业务过程中所需要的信息的格式相同。其中，上述开通信息，包括以下至少之一：从IMS中业务支撑系统中获取的用户数据、从ENUM服务器中获取的数据、从应用服务器AS中获取的业务信息。上述处理过程在具体应用时可以表现为以下形式，但不限于此：
步骤101：当用户发起业务开通请求时，业务支撑系统将用户的基本数据开通到开通事务管理实体。此类用户数据包括：IP多媒体公共标识IMPU、IMPI、鉴权密码、IMS口令、IMS核心网密码和初始化过滤规则(Initial Filter Condition，简称为IFC)等。当开通了用户数据后，用户只能注册到IMS，并不能使用IMS的任何业务。
步骤102：业务支撑系统将ENUM网元相关的数据开通到开通事务管理实体，此类数据包括电话统一资源标识(TEL Uniform Resource Identifier，简称为TEL URI)和会话开始协议统一资源标识(Session Initiation Protocol URI，简称为SIP URI)的映射关系。
TEL URI和SIP URI的映射关系用以支撑该用户作为被叫时，在核心网的路由能力。
步骤103：业务支撑系统将AS相关的业务信息，例如，MMTel语音业务，补充业务数据，用户属性等，开通到开通事务管理实体。
至此，用户完成业务的开通，当用户能够登陆IMS，使用相应的MMTel语音业务。
在本实施例中，还提供了一种IMS中的业务开通装置，该装置中所涉及到的各个模块可以通过软件或硬件实现，如图4所示，该装置包括：
发送模块40，设置为在所述指定IMS业务的开通过程中，向IMS中设置的开通事务管理实体发送查询请求，其中，所述开通事务管理实体存储有所述IMS中各个网元在开通指定IMS业务过程中所需要的开通信息；
接收模块42，连接至发送模块，设置为接收所述开通事务管理实体根据所述查询请求反馈的所述开通信息。
通过上述各个模块所实现的功能，同样可以将业务开通所需要的信息均存储在开通事务管理实体中，这样IMS中在业务开通时所涉及的各个网元从该开通事务管理实体中获取业务开通所需要的信息，从而解决现有的IMS业务开通过程涉及到的网元较多导致开通效率低、可靠性差、不利于业务扩展等技术问题。
正如前面所述，上述实施例中的各个模块是可以通过硬件来实现的。例如可以通过以下方式实现，但不限于此：发送模块40和接收模块42分别位于第一处理器和第二处理器中，或者：发送模块40和接收模块42位于同一处理器中。
实施例2
在本实施例中，还提供了另外一种IMS中的业务开通方法，该方法通过在IMS中设置开通事务管理实体实现，该开通事务管理实体存储有所述IMS中各个网元在开通指定IMS业务过程中所需要的开通信息，如图5所示，该方法包括：
步骤S502，在业务开通过程中，开通事务管理实体接收IMS中各个网元的查询请求；
步骤S504，开通事务管理实体向上述各个网元发送与查询请求对应的开通信息。
需要说明的是，上述处理步骤中接收或发送来自各个网元的信息的时间可以是同一时间或不同时间，具体根据不同业务开通过程确定。
在本实施例中，开通事务管理实体中存储的开通信息可以通过以下方式获取，但不限于此：通过IMS中的业务支撑系统将上述各个网元的开通信息存储至开通事务管理实体。
在一个优选实施例中，开通事务管理实体中存储的开通信息与上述各个网元在开通IMS业务过程中所需要的信息的格式相同。
上述开通信息，包括但不限于以下至少之一：从所述IMS中业务支撑系统中获取的用户数据、从电话号码映射ENUM服务器或域名服务器(Domain Name Server，简称为DNS)中获取的数据、从应用服务器AS中获取的业务信息。由此可见，业务开通过程中所涉及到的上述“各个网元”可以包括但不限于：业务支撑系统、AS、DNS、ENUM。
为实现上述方法，本实施例还提供一种IMS中的业务开通装置，如图6所示，该装置包括：
接收模块60，设置于开通事务管理实体中，设置为在业务开通过程中，接收IMS中各个网元的查询请求，其中，该开通事务管理实体存储有所述IMS中各个网元在开通指定IMS业务过程中所需要的开通信息；
发送模块62，连接至接收模块60，设置于开通事务管理实体中，设置为向上述各个网元发送与上述查询请求对应的开通信息
上述实施例中的各个模块是可以通过硬件来实现的。例如可以通过以下方式实现，但不限于此：发送模块62和接收模块60分别位于第一处理器和第二处理器中，或者：发送模块62和接收模块60位于同一处理器中。
在本实施例中，还提供一种IMS，该IMS中新增加了开通事务管理实体，如图7所示，该IMS包括：
业务支撑系统70，设置为将在指定IMS业务的开通过程中各个网元所需要的开通信息均开通至开通事务管理实体；
开通事务管理实体72，设置为存储上述开通信息，并在上述开通过程中向各个网元提供上述开通信息；
各个网元74，设置为直接或间接向开通事务管理实体请求上述开通信息，以及进行网元间的信息交互，以实现业务开通。
如图8所示，上述各个网元可以包括但不限于以下实体：
用户签约数据存储实体740(例如HSS/SLF)，设置为在上述开通过程中读取上述开通事务管理实体中存储的用户数据；
在本发明实施例的一个优选示例中，用户签约数据存储实体740，还设置为接收服务呼叫会话控制功能S-CSCF实体根据接收的用户注册请求发送的用户授权UAR请求，并向开通事务管理实体发送用于查询用户信息的查询请求，以及向S-CSCF实体发送UAR请求的响应消息，其中，该响应消息中携带有上述用户信息。
应用服务器742，设置为在上述开通过程中直接或通过上述用户签约数据存储实体读取上述开通事务管理实体中存储的业务数据，并根据该业务数据实现相应的业务；
在本发明实施例的一个优选示例中，应用服务器742，还设置为接收来自S-CSCF实体的服务器的业务请求；以及直接或者通过用户签约数据存储实体向开通事务管理实体发送用于获取业务数据的查询请求；和/或，用户签约数据存储实体740，还设置为接收来自S-CSCF实体的请求消息，并向开通事务管理实体请求业务数据，其中，S-CSCF实体在用户注册成功后发送请求消息。
电话号码映射ENUM服务器或域名服务器DNS 744，设置为在上述开通过程中读取上述开通事务管理实体中存储的电话统一资源标识TEL URI和会话初始化统一资源标识SIP URI的映射关系，以及DNS数据。
本发明实施例对上述技术方案的进一步改进在于，开通事务管理实体，还设置为与所述各个网元协商确定开通信息的格式，其中，协商确定后的格式与各个网元所需要的开通信息的格式一致。
为了更好地理解上述实施例1-2，以下结合一个优选实施例详细说明。
实施例3
在该优选实施例中以上述开通事务管理实体为开通事务管理实体为例进行说明，但不限于此。以下优选实施例的主要设计思想在于：所有的开通数据统一存放在开通事务管理实体，业务支撑系统与开通事务管理实体之外的网元没有接口；业务支撑系统开通的数据是与网元协商确定的数据格式，不需要开通事务管理实体进行数据格式转换；开通事务管理实体提供数据的增加、删除、修改、查询的接口，接口采用的协议不限，典型的协议是轻量目录访问协议(Lightweight Directory Access Protocol，简称为LDAP)。在业务处理流程中，各网元如果需要使用数据，通过与开通事务管理实体交互获得。
在本实施例中涉及的IMS业务开通架构可以基于图8所示IMS，但不限于此，其中：
业务支撑系统，负责将IMS中各网元(HSS，AS，ENUM/DNS等)需要的各类数据统一开通到开通事务管理实体，并且要求开通的数据格式是各网元需要的数据格式；
开通事务管理实体，统一存放IMS系统各网元的开通数据，各网元可以通过统一的接口读写用户的开通数据，并且提供接口允许对开通数据的增加、删除、修改、查询。
HSS/SLF，负责读取开通事务管理实体中存放的用户开通的基本数据，同时可以作为AS的代理读写开通事务管理实体中存放的用户开通的业务数据。
AS，可以直接或间接通过HSS读写开通事务管理实体中存放的用户开通的业务数据，并使用业务数据实现相应的业务。
ENUM/DNS，负责读取开通事务管理实体中存放的用户开通的TEL URI和SIP URI的映射关系，以及DNS数据。
图9示出了改进的IMS业务开通流程，以开通MMTel语音业务为例进行说明，具体步骤如下：
步骤S902：当用户发起开通MMTel语音业务的业务开通请求时，业务支撑系统将用户的基本数据开通到开通事务管理实体。此类用户数据包括：IP多媒体公共标识(IP Multimedia Public Identity，IMPU)、IP多媒体私有标识(IP Multimedia Private Identity，简称为IMPI)、鉴权密码、IMS口令、IMS核心网密码和初始化过滤规则(Initial Filter Condition，简称为IFC)等，具体的数据定义在3GPP TS 29.228中进行了描述。
当开通了用户数据后，用户只能注册到IMS，并不能使用IMS的MMTel语音业务。
步骤S904：业务支撑系统将ENUM网元相关的数据开通到开通事务管理实体，此类数据包括电话统一资源标识(TEL Uniform Resource Identifier，简称为TEL URI)和会话开始协议统一资源标识(Session Initiation Protocol URI，简称为SIP URI)的映射关系。
TEL URI和SIP URI的映射关系用以支撑该用户作为被叫时，在核心网的路由能力。
步骤S906：激活某个业务；业务支撑系统将MMTel语音业务数据，按照MMTel AS要求的数据格式将业务数据开通到开通事务管理实体，例如，补充业务的数据在3GPP TS 29.364中有定义：
Figure PCTCN2014088775-appb-000001
Figure PCTCN2014088775-appb-000002
步骤S908：读写HSS用户数据业务；
步骤S910：读写AS用户业务数据；
步骤S912：读写AS用户业务数据；
至此，用户完成MMTel语音业务的开通。
图10示出了业务开通后的用户注册流程，以开通了MMTel语音业务为例，其中，MMTel AS通过HSS间接从开通事务管理实体读取数据。具体步骤如下：
和图9类似，首先执行以下步骤：当用户能够登录IMS，服务呼叫会话控制功能实体(Serving-CSCF，简称为S-CSCF)收到用户的注册请求，向HSS发送获取用户信息的用户授权请求(User Authorization Request，简称为UAR)(参见3GPP TS 29.228)，请求鉴权数据；HSS向开通事务管理实体发送查询请求，获得UAR请求中需要的信息；HSS返回UAA响应给S-CSCF，S-CSCF继续正常的注册流程；当用户成功注册后，S-CSCF发送SAR请求给HSS，请求用户的iFC等业务触发数据；HSS向开通事务管理实体发送查询请求，获得SAR请求中需要的信息；HSS返回结果给S-CSCF；
然后执行图10所示步骤：
步骤S1002：S-CSCF发送SIP注册(REGISTER)请求给MMTel AS进行第三方注册；
步骤S1004：MMTel AS收到第三方注册请求后，向HSS/SLF发送UDR请求(参见3GPP TS 29.328)，请求获得补充业务数据；
步骤S1006：HSS/SLF向开通事务管理实体发送查询请求，获得用户数据请求UDR(Use Data Request，简称为UDR)请求中需要的数据库数据(Repository Data)，如表1所示。

步骤S1008：开通事务管理实体向HSS/SLF返回MMTel信息。
步骤S1010：HSS/订阅定位功能(SubscriptionLocatorFunction，简称为SLF)返回结果给MMTel AS。
步骤S1012：MMTel AS返回第三方注册成功的200 OK响应给S-CSCF。
至此，完成用户在IMS的注册过程，可以实现MMTel业务。
图11示出了业务开通后的用户注册流程，以开通MMTel语音业务为例，其中，MMTel AS直接从开通事务管理实体读取数据。具体步骤如下：
在执行图11所示步骤之前，需要先执行以下步骤：当用户能够登录IMS，S-CSCF收到用户的注册请求，向HSS发送获取用户信息的UAR请求(参见3GPP TS29.228)，请求鉴权数据；HSS向开通事务管理实体发送查询请求，获得UAR请求中 需要的信息；HSS/SLF返回UAA响应给S-CSCF，S-CSCF继续正常的注册流程；当用户成功注册后，S-CSCF发送服务器分配请求(Server-Assignment-Request，简称为SAR)请求给HSS/SLF，请求用户的iFC等业务触发数据；HSS/SLF向开通事务管理实体发送查询请求，获得SAR请求中需要的信息；HSS返回结果给S-CSCF。
如图11所示，还包括以下处理步骤：
步骤S1102：S-CSCF发送SIP REGISTER请求给MMTel AS进行第三方注册；
步骤S1104：MMTel AS收到第三方注册请求后，直接将开通事务管理实体发送查询请求，请求获得补充业务数据；

步骤S1106：MMTel AS返回第三方注册成功的200 OK响应给S-CSCF。
图12示出了业务开通后的用户注册流程，以S-CSCF通过HSS间接从开通事务管理实体读取数据为例。具体步骤如下：
步骤S1202：当用户能够登录IMS，S-CSCF收到用户的注册请求，向HSS发送获取用户信息的UAR请求(参见3GPP TS 29.228)，请求鉴权数据；
步骤S1204：HSS向开通事务管理实体发送查询请求(查询用户的鉴权信息)，获得UAR请求中需要的信息；
步骤S1206：HSS返回UAA响应给S-CSCF(携带用户鉴权响应User-Authorization-Answer，简称为UAA)，S-CSCF继续正常的注册流程；
步骤S1208：当用户成功注册后，S-CSCF发送SAR请求给HSS，请求用户的iFC等业务触发数据；
步骤S1210：HSS向开通事务管理实体发送查询请求，获得SAR请求中需要的信息，即更新用户的注册信息，并下载业务触发信息；
步骤S1212：HSS返回结果(SAA)给S-CSCF。
综上所述，本发明实施例实现了以下有益效果：有效解决了现有IMS开通技术中存在的开通效率低，可靠性差，不利于扩展等缺点，极大提升了IMS网络的可运营性，并且该方案可以扩展到其他通信领域，有非常高的通用性。
