- - Application identifier An application is identified by the carrier ID and the application ID. Currently the carrier ID is set to "0". A routing entry may have different destinations based on the Attribute Value Pair (AVP) in the message. The application identifier must be used as the second key field for the routing table query.

Description
一种 Diameter路由方法和***
技术领域 本发明涉及移动通信领域,尤其涉及一种 Diameter路由方法和***以及 一种 MGCF设备。
背景技术
在通信网络***普遍应用的今天,为了保障通信网络的安全和商业用途, 通信网络中各类资源的使用, 需要通过通信网络***支持认证、 授权和计费 功能。 目前,通信网络***使用的两种主流鉴别、授权、计费 (Authentication, Authorization ¾ Accounting, AAA )应用协议为 Radius 和 Diameter协议。 Diameter协议是新一代的 AAA技术, 它克服了 Radius协议的诸多弊端, 并 以其强大的可扩展性和安全保证, 正得到越来越多的关注。 在国际电信联盟 ( International Telecommunication Union, ITU ) 、 第三代合作伙伴计划 ( 3rd Generation Partnership Proj ect, 3 GPP )和 3 GPP2等国际标准组织中, 已经正 式将其作为下一代网络(Next Generation Network, NGN ) 、 宽带码分多址 ( Wideband Code Division Multiple Access, WCDMA )和 CDMA2000等未来 通信网络的首选 AAA协议。
CDMA2000 ***中, 在传统 CDMA 网络与 IP 多媒体子*** ( (IP Multimedia Subsystem, IMS ) 网络互通时, 呼叫接通通话后, 需传统 CDMA 网络中的媒体网关控制功能( Media Gateway Control Function, MGCF )网元 将通话的计费信息发送给 IMS网络中的计费网关 ( Charging Gateway, CG ) 计费中心, 目前业内通常釆用 Diameter协议来传递计费信息。 在 RFC3588 Diameter协议中规定了 Diameter消息路由釆用基于域的路 由表方式。 所有基于域的路由查找都是依靠域路由表来执行的。 域路由表入 口包含以下字段:
——域名。 该字段通常用作路由表查询中的主关键字。 注意, 某些实际 应用在执行查询时是基于"从右端最长匹配"的原则, 而不要求完全匹配。
——应用标识符。 一个应用是由运营商 ID和应用 ID来标识的。 目前 运营商 ID 均定为 "0"。 一个路由入口基于消息中的应用标识属性值对 ( Attribute Value Pair, AVP), 可能拥有不同的目的地。 应用标识符必须用作 路由表查询的第二关键字字段。 ——本地动作。本地动作字段用来标识一个消息将被如何处理。支持以 下动作:
•本地(LOCAL ) -本地动作设置为 LOCAL 的 Diameter 消息可以在本 地处理, 无需被路由到其它服务器。
•中继(RELAY ) -所有属于本类型的 Diameter 消息必须被路由到下一 跳的服务器, 无需修改任何非路由 AVP。
•代理(PROXY ) -所有属于本类型的 Diameter 消息必须被路由到下一 跳的服务器。本地服务器可以在路由之前通过将新的 AVP***到该消息中, 来实行本地策略。
•重定向 (REDIRECT ) -所有属于本类型的 Diameter 消息必须附加归 属 Diameter服务器的标识, 并且返回给消息的发送者。 从上文描述可以看出, 对于 Diameter消息路由釆用域名作为主关键字, 而此时 MGCF向 CG计费中心发送消息时, 釆用 CG的域名作为消息路由的 主关键字。 如图 1所示, 为了实现不同 CG计费中心管理不同号码, IMS网 元需要根据不同号码通过配置映射为不同的 CG域名, 在呼叫接通时传递给 MGCF网元。 图 1为基于域名进行 Diameter路由的计费上报流程图, 包括:
101 : IMS网元投入运行前, 将不同号码或号码段映射为不同 CG域名。 如 999900001〈-〉 cgl.example.com.cn, 888800001〈-〉 cg2.example.com.cn。
102: CDMA网络用户呼叫 IMS用户或 IMS用户呼叫 CDMA网络用户, MGCF与 IMS网元之间呼叫建立, IMS网元将 CG域名传递给 MGCF。
103: MGCF以 CG域名作为主关键字, 在路由表中查找到路由记录, 得 到本地动作为: RELAY, 向外发送计费请求 (Accounting Request, ACR )
消息。
104: MGCF将编码后的 ACR消息, 通过底层链路将消息发送给 IMS 网元。
105: CG计费中心接收到 ACR消息, 提取消息中的目的域名 AVP , 作 为主关键字在路由表中查找路由记录, 得到结果本地动作为: LOCAL, 消息 在本 CG计费中心处理。
106: CG计费中心处理完 ACR消息,向 MGCF返回计费响应( Accounting Answer, ACA ) 消息, 编码后通过底层链路发送给 MGCF网元。 釆用图 1描述的方式, 实现不同 CG管理不同号段用户, 缺点在于需在 IMS网元进行用户号码与 CG域名对应关系设定, 同时在呼叫过程中需根据 用户号码得到 CG域名, 发送给 MGCF网元, 这样也增加了 IMS与 MGCF 网元之间的消息流量。
发明内容
本发明要解决的技术问题是提出一种 Diameter路由方法和***及一种

本发明的较佳实施方式 本发明提供一种 Diameter路由方法, 包括: CDMA网络用户和 IP多媒 体子***(IMS )用户建立呼叫后, 在发送计费信息给 IMS网络的过程中, 使用所述 IMS用户的用户号码作为 Diameter消息路由的主关键字查找路由。 其中,在 CDMA网络用户呼叫 IMS用户时,釆用被叫号码作为 Diameter 消息路由的主关键字; 在 IMS用户呼叫 CDMA网络用户时, 釆用主叫号码 作为 Diameter消息路由的主关键字。 其中, 媒体网关控制功能( MGCF )配置并保存 IMS用户的用户号码与 计费网关的映射关系; 当 CDMA网络用户呼叫 IMS用户时, 包括: 所述 MGCF 提取被叫号码, 使用所述被叫号码作为主关键字查找路由 表, 得到对应的计费网关, 向所述计费网关发送计费请求消息, 所述计费请 求消息中携带被叫号码信息; 所述计费网关接收到所述计费请求消息后, 从所述计费请求消息中提取 所述被叫号码和主叫号码, 判断至少其中之一属于所述计费网关时, 接收并 处理所述计费请求消息。 当 IMS用户呼叫 CDMA网络用户时, 包括: MGCF提取主叫号码, 使 用所述主叫号码作为主关键字查找路由表, 得到对应的计费网关, 向所述计 费网关发送计费请求消息, 所述计费请求消息中携带主叫号码信息; 所述计费网关接收到所述计费请求消息后, 从所述计费请求消息中提取 所述被叫号码和主叫号码, 判断至少其中之一属于所述计费网关时, 接收并 处理所述计费请求消息。
下文中将结合附图对本发明的实施例进行详细说明。 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任意组合。
图 2和图 3给出两种基于用户号码进行 Diameter路由的计费消息上报流 程图, 可以发现两种方式适用于不同的业务场景, 当 CDMA 网络用户呼叫 IMS 用户时, 需使用被叫号码作为查询路由表关键字, 当 IMS 用户呼叫 CDMA网络用户时, 需使用主叫号码作为查询路由表关键字。 图 2为当 CDMA网络用户呼叫 IMS用户时,基于被叫号码进行 Diameter 路由的计费上报流程图, 包括:
201 : 首先 MGCF网元需进行数据配置, 配置 IMS用户号码与不同 CG 之间映射关系, 并保存在 MGCF网元中, 例如 9999****号段用户映射 CG1 , 8888****号段用户映射 CG2。 202: CDMA网络用户呼叫 IMS网络中用户,通过会话初始协议( Session
Initiation Protocol , SIP )呼叫接续, 此时比如 IMS用户号码为 99990001。
203: MGCF网元提取出呼叫过程中的被叫号码 99990001 , 根据在步骤 201所做的数据配置, 以被叫号码作为主关键字查找路由表, 基于"从右端最 长匹配"的原则, 得到结果为 CG1 , 并且本地动作为: RELAY; 204: MGCF向 CGI发送 ACR消息, 消息中携带被叫号码信息。
205: CG1接收到该 ACR消息, 从消息中提取出主叫号码与被叫号码, 分别判断号码是否属于本 CG,如至少其中一个号码属于本 CG,则本地处理, 此时被叫号码 99990001属于 CG1 , 接受处理此 ACR消息。
206: CG1处理完 ACR消息, 向 MGCF返回 ACA消息。
图 3为当 IMS用户呼叫 CDMA网络用户时,基于主叫号码进行 Diameter 路由的计费上报流程图。
301 : 首先 MGCF网元需进行数据配置, 做好 IMS用户号码与不同 CG 之间映射关系, 并保存在网元中。 例如 9999****号段用户映射 <->CGl , 8888****号段用户映射 <->CG2。
302: IMS网络中用户呼叫 CDMA网络用户, 通过 SIP呼叫接续, 此时 比如 IMS用户号码为 99990001。
303: MGCF网元提取出呼叫过程中的主叫号码 99990001 , 根据在步骤 301所做的数据配置, 以主叫号码作为主关键字查找路由表, 基于"从右端最 长匹配 "的原则, 得到结果 CG1 , 并且本地动作为: RELAY, 向 CG1 发送 ACR消息。 304: MGCF向 CG1发送 ACR消息, 消息中携带主叫号码 AVP信息。
305: CG1接收到 ACR消息, 从消息中提取出主叫号码与被叫号码, 分 别判断号码是否属于本 CG1 , 如至少其中一个号码属于本 CG, 则本地处理, 此时主叫号码 99990001属于 CG1 , 接受处理此 ACR消息。
306: CG1处理完 ACR消息, 向 MGCF返回 ACA消息。
本发明还提供一种 Diameter路由***, 所述***包括媒体网关控制功能 ( MGCF ) ,该 MGCF设置为:在 CDMA网络用户和 IP多媒体子***( IMS ) 用户建立呼叫后, 在发送计费信息给 IMS网络的过程中, 使用 IMS用户的 用户号码作为 Diameter消息路由的主关键字查找路由。 其中, 当 CDMA网 络用户呼叫 IMS用户时, 使用被叫号码作为 Diameter消息路由的主关键字; 当 IMS用户呼叫 CDMA网络用户时, 使用主叫号码作为 Diameter消息路由 的主关键字。 所述 MGCF还设置为: 配置并保存 IMS用户的用户号码与计费网关的 映射关系。 所述 MGCF设置为当 CDMA网络用户呼叫 IMS用户时,提取被叫号码, 使用所述被叫号码作为主关键字查找路由表, 得到对应的计费网关, 向所述 计费网关发送计费请求消息, 所述计费请求消息中携带被叫号码信息。 所述 MGCF设置为当 IMS用户呼叫 CDMA网络用户时,提取主叫号码, 使用所述主叫号码作为主关键字查找路由表, 得到对应的计费网关, 向所述 计费网关发送计费请求消息, 所述计费请求消息中携带主叫号码信息。 其中, 所述***还包括计费网关, 所述计费网关设置为: 接收到所述计 费请求消息后, 从所述计费请求消息中提取所述被叫号码和主叫号码, 判断 至少其中之一属于所述计费网关时, 接收并处理所述计费请求消息。
本发明还提供了一种媒体网关控制功能(MGCF )设备, 该 MGCF设备 设置为: 在 CDMA网络用户和 IP多媒体子***(IMS )用户建立呼叫后, 在发 送计费信息给 IMS网络的过程中, 使用 IMS用户的用户号码作为 Diameter 消息路由的主关键字查找路由。 所述 MGCF设备是设置为: 当 CDMA网络用户呼叫 IMS用户时, 使用 被叫号码作为 Diameter消息路由的主关键字; 当 IMS用户呼叫 CDMA网络 用户时, 使用主叫号码作为 Diameter消息路由的主关键字。 所述 MGCF设备还设置为: 配置并保存 IMS用户的用户号码与计费网 关的映射关系; 所述 MGCF设备是设置为按如下方式使用 IMS 用户的用户号码作为 Diameter消息路由的主关键字查找路由: 当 CDMA网络用户呼叫 IMS用户 时, 提取被叫号码, 使用所述被叫号码作为主关键字查找路由表, 得到对应 的计费网关; 以及 所述 MGCF设备还设置为: 向所述计费网关发送计费请求消息, 所述计 费请求消息中携带被叫号码信息。 所述 MGCF设备还设置为: 配置并保存 IMS用户的用户号码与计费网 关的映射关系; 所述 MGCF设备是设置为按如下方式使用 IMS 用户的用户号码作为 Diameter消息路由的主关键字查找路由: 当 IMS用户呼叫 CDMA网络用户 时, 提取主叫号码, 使用所述主叫号码作为主关键字查找路由表, 得到对应 的计费网关; 所述 MGCF设备还设置为: 向所述计费网关发送计费请求消息, 所述计 费请求消息中携带主叫号码信息。
通过以上方法, 不再需要 IMS将 CG的域名发送给 MGCF, 实现不同用 户的计费消息发送到其归属的 CG计费中心。 而且由于 IMS不需将 CG的域
名发送给 MGCF, 达到减少消息流量的效果。 根据号码进行 Diameter路由, 在进行网络规划时, 可实现不同 CG计费中心管理不同号段的用户, 便于网 络管理。 本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序 来指令相关硬件完成, 所述程序可以存储于计算机可读存储介质中, 如只读 存储器、 磁盘或光盘等。 可选地, 上述实施例的全部或部分步骤也可以使用 一个或多个集成电路来实现。 相应地, 上述实施例中的各模块 /单元可以釆用 硬件的形式实现, 也可以釆用软件功能模块的形式实现。 本发明不限制于任 何特定形式的硬件和软件的结合。
工业实用性 本发明利用呼叫中的主叫号码或被叫号码作为 Diameter消息路由的主关 键字,不需要在 IMS网元进行用户号码与 CG域名对应关系设定,不需要 IMS 网元在呼叫过程中根据用户号码得到 CG域名发送给 MGCF网元,减少了消 息流量。 另外, 由于在 MGCF发送给 CG计费中心的 ACR消息中, 目前已 具有主叫号码与被叫号码, 所以不需要增加额外的开销。
