具体实施方式
在这里描述的主题包含用于丰富Diameter信令消息的方法、系统和计算机可读介质。如这里使用的那样,术语Diameter指的是由RFC3588定义的由电信和计算机网络利用的认证、授权和计账(AAA)协议。在一个实施例中,本主题可包含接收与特定的移动订户相关的Diameter信令消息的Diameter信令路由(DSR)。接收的Diameter信令消息还可要求来自诸如网络计费功能节点(例如,计费数据功能(CDF)、策略和计费规则功能(PCRF)等)的特定类型的网络服务节点的处理。在接收Diameter信令消息时,DSR节点可被配置为询问Diameter绑定仓库(DBR)以确定处理接收的Diameter信令消息的优选网络服务节点。在一个实施例中,询问消息触发DBR以检查存储的绑定记录以确定优选的网络服务节点是否已被分配(或“绑定”)到移动订户。如这里使用的那样,绑定记录可包括包含在分配的网络服务节点与移动订户信息(例如,标识符)之间形成的一个或多个关联的电子记录。因此,DBR可获得存储于绑定记录中的DBR信息并将其提供给DSR。DSR可随后修改指向优选的网络服务节点的Diameter信令消息以包含接收的DBR信息的至少一部分。因此,优选的网络服务节点可具有包含附加的移动订户信息、与移动订户相关的附加的会话标识符和与支持移动订户的其它网络服务节点相关的识别/身份/地址信息的丰富的Diameter信令消息。在一个实施例中,可在长期发展(LTE)网络和/或因特网协议多媒体子系统(IMS)网络中实现本主题。作为替代方案,在不背离本主题的范围的情况下,可在其它的网络中部署本主题。
图1示出包括可被用于丰富Diameter信令消息的大量的各种网络要素的示例性系统100。在一个实施例中,系统100包含被配置为接收与移动订户相关的Diameter信令消息的Diameter路由节点,例如DSR104。虽然图1示出DSR的用户,但是,在不背离本主题的范围的情况下,可以利用被配置为路由Diameter信令消息的任何网络节点。例如,网络节点还可包含Diameter路由代理(DRA)、Diameter委托代理(DPA)、Diameter中继代理、Diameter转换代理和Diameter重定向代理等。在一个实施例中,DSR104包含可被配置为在各种Diameter接口上的各种Diameter节点之间路由Diameter信令消息的Diameter路由引擎(DRE)122,这些Diameter接口包含但不限于Gy、Ro、Rf、S6d和S6a接口。由DSR104接收的示例性的基于Diameter的信令消息包含信用控制请求(CCR)消息、计账请求(ACR)消息、更新位置请求(ULR)消息、Diameter可动管理消息和Diameter计费消息。在一个实施例中,由Diameter路由节点接收的Diameter信令消息可通过诸如例如策略和计费增强功能(PCEF)节点、网关GPRS支持节点(GGSN)、可动管理实体(MME)和公共数据网络(PDN)网关的网络节点(未示出)被发送。DSR104还可包含被配置为与一个或多个DBR(例如,DBR102)通信(例如,发送询问/请求消息和接收回答/响应消息)的绑定询问客户机(BQC)124。
在一个实施例中,由DSR104接收的Diameter信令消息可最初被指定或寻址到能够处理Diameter信令消息的网络服务节点。虽然图1示出Diameter信令消息可被路由到的示例性的多个网络服务节点,诸如CDF1121,,,m和PCRF1141,,,n,但是,在不背离本主题的范围的情况下,可以在系统100中利用被配置为用于服务Diameter信令消息的任何其它类型的网络服务节点。例如,网络服务节点可包含策略和计费规则功能(PCRF)网络、网络计费节点(例如,计费数据功能(CDF)、计费触发功能(CTF)、计费网关功能(CGF))、在线计费系统(OCS)节点、离线计费系统(OFCS)节点、家庭订户服务器(HSS)节点、家庭位置登记节点(HLR)、AAA节点和呼叫会话控制功能(CSCF)节点。
在图1中,系统100还包括包含托管绑定记录数据库128的绑定询问服务器(BQS)126的Diameter绑定仓库(DBR)102。在一个实施例中,绑定记录数据库128可被配置为存储包含移动订户标识符与分配的网络服务节点之间的关联(例如,与Diameter相关的绑定、映射、链接等)的绑定记录。由DBR102存储的示例性的Diameter相关绑定可包含但不限于Diameter会话绑定、Diameter会话标识符到网络服务节点关联、Diameter端对端标识符到网络服务节点关联、移动订户标识符到网络服务节点关联和计费标识符到网络服务节点关联等。在一个实施例中,计费标识符可包含IMS计费ID。在后面在图5中描述示例性的绑定记录数据库128。
在这里示出的实施例中,DBR102被示为独立实体,诸如网络节点、计算机、服务器、应用或位置与DSR104分开的数据库。但是,在其它的实施例(未示出)中,DBR102可共处于DSR内或者共处于任何其它网络节点内。虽然在图1中仅示出单个DSR和单个DRB,但是,在不背离本主题的范围的情况下,本主题可包含与DSR104和DBR102通信连接的附加的DSR和DBR。
图2是示出根据这里描述的主题的实施例的丰富Diameter信令消息的示例性的基于Diameter的消息序列图。如图2所示,DSR104接收包含移动订户相关信息的Diameter信令消息即信用控制请求(CCR)消息201。在本例子中,移动订户相关信息包含用户名(例如,“用户名X”)和会话标识符(例如,“会话ID_1”)。在一个实施例中,会话标识符用作用于在发送CCR消息的网络节点(例如,PCEF)与最终被选择为处理CCR消息的网络服务节点之间建立的通信会话的标识符。
在一个实施例中,DSR104可被配置为从接收的Diameter信令消息提取移动订户相关信息。从Diameter路由消息提取的移动订户相关信息的例子包含但不限于Diameter会话标识符信息、用户名信息、国际移动订户身份(IMSI)信息、IMS私人身份(IMPI)信息、IMS公共身份(IMPU)信息、会话初始协议(SIP)统一资源标识符(URI)信息、网络访问标识符(NAI)信息、移动/可拨号信息、移动订户目录号信息、IMS计费标识符信息、移动站国际订户目录号(MSISDN)信息和用户因特网协议(IP)地址信息。返回图2,CCR消息201包含用户名和由DSR104提取的会话标识符。
在一个实施例中,DSR104还可被配置为将提取的移动订户相关信息插入DBR询问消息中。例如,DSR104可产生用于请求能够处理CCR消息201的网络服务节点的身份和/或地址的DBR询问消息202。在一个实施例中,DSR104被配置为将从消息201提取的用户名和会话标识符信息插入到询问消息202中。
如图2所示,DBR102可从DSR104接收包含例如会话标识符和与移动订户相关的用户名标识符的提取的移动订户相关信息的DBR询问消息202。在一个实施例中,DBR102可被配置为通过存储于包含于记录数据库128中的绑定记录的移动订户标识符的列表交叉引用接收的用户名标识符,该绑定记录数据库128包含多个绑定记录。如果交叉引用过程导致定位匹配提取的用户名标识符的条目,那么DBR102可获得包含于与匹配条目相关的绑定记录中的DBR信息。在一个实施例中,绑定记录包含用户IP地址、IMPI、IMPU、用户名标识符和相关网络服务节点标识符/身份/地址。如果提取的用户名标识符匹配该特定绑定记录中的用户名标识符,那么DBR102可获得绑定到用户名标识符的网络服务节点标识符(例如,识别CDF标识符1121的标识符)。DBR102还可获得存储于相同的绑定记录中并与移动订户相关(即,匹配用户名)的多个其它的标识符。例如,DBR102可从绑定记录获得用户IP地址、IMPI和IMPU。
在从记录数据库128获得DBR信息之后,DBR102可然后产生包含DBR信息的DBR响应消息203并随后将响应消息203路由到DSR104。如图2所示,DBR信息可包含诸如网络服务节点身份/地址(例如,用于CDF1121的标识符)、用户名标识符、用户IP地址、IMPI和与移动订户相关的IMPU的参数/标识符。
图2还示出DSR104从DBR102接收包含DBR信息的DBR响应消息203。DSR104可然后使用接收的DBR信息连同网络服务节点标识符信息(例如,CDF1121)以修改/丰富原接收的基于Diameter的CCR消息201。特别地,DSR104将DBR信息的至少一部分(例如,一些或全部)插入原CCR消息201中,使得产生修改的CCR消息204。如图1所示,CCR消息201被修改,使得用户IP地址、IMPI和IMPU被添加到原会话标识符和包含于消息201中的用户名,这导致修改的CCR消息204。DSR104还可被配置为使用获得的网络服务节点标识符(即,包含于消息203中的CDF标识符)以将消息204寻址和路由到CDF1121。在替代性实施例中,DSR104可被配置为产生包含DBR信息中的一些或全部的全新的CCR消息而不是修改原接收的CCR消息201。
图3是示出根据这里描述的主题的实施例的用附加移动订户相关会话信息丰富Diameter信令消息的示例性的基于Diameter的消息序列图。如图3所示,DSR104接收包含移动订户相关信息的Diameter信令消息,即,信用控制请求(CCR)消息301。在本例子中,移动订户相关信息包含用户名(例如,“用户名X”)和会话标识符(例如,“会话ID_1”)。在一个实施例中,会话标识符用作用于在发送CCR消息的节点与最终被选择为处理CCR消息的网络服务节点之间建立的通信会话的标识符。在一个实施例中,DSR104可被配置为从接收的CCR消息301提取移动订户相关信息,诸如用户名标识符/身份和会话标识符。
在一个实施例中,DSR104还可被配置为将提取的移动订户相关信息插入DBR询问消息中。例如,DSR104可产生用于请求能够处理CCR消息301的网络服务节点的身份、标识符和/或地址的DBR询问消息302。在一个实施例中,DSR104被配置为将从消息301提取的用户名和会话标识符信息插入到询问消息302中。
如图3所示,DBR102可从DSR104接收包含例如会话标识符和与移动订户相关的用户名标识符的提取的移动订户相关信息的DBR询问消息302。在一个实施例中,DBR102可被配置为通过存储于包含于记录数据库128(在图1中示出)中的绑定记录的移动订户标识符的列表交叉引用接收的用户名标识符。如果交叉引用过程导致定位匹配提取的用户名标识符的条目,那么DBR102可获得包含于与匹配条目相关的绑定记录中的DBR信息。例如,DBR102可获得在绑定记录中绑定到匹配的用户名标识符的网络服务节点标识符(例如,CDF标识符1121)、身份或地址。DBR102还可获得存储于相同的绑定记录中并与移动订户相关的多个其它的标识符/参数。例如,绑定记录可指示与用户名标识符相关的用户IP地址、IMPI和IMPU。
另外,DBR102还可获得识别在第二网络服务节点(例如,“PCRF_1”)与寻求获得关于移动订户的信息的另一Diameter网络节点之间建立的通信会话的第二会话标识符。例如,DBR102可从数据库128中的相同的上述的绑定记录获得会话标识符“会话ID_2”和网络服务节点标识符“服务PCRF_1”。在本例子中,“PCRF_1”被事先指定为提供用于询问Diameter节点的服务或处理信息,该Diameter节点请求了关于与“用户名X”相关的移动订户的信息。
在从数据库128获得DBR信息之后,DBR102可然后产生包含DBR信息的DBR响应消息303并随后将响应消息303路由到DSR104。如图3所示,DBR信息可包含诸如第一网络服务节点身份/地址(例如,用于CDF1121的标识符)、用户名标识符、用户IP地址、IMPI和与移动订户相关的IMPU的参数/标识符。注意,消息303还可包含第二会话标识符和第二网络服务节点标识符/身份。
图3还示出DSR104从DBR102接收包含DBR信息的DBR响应消息303。DSR104可然后使用接收的DBR信息连同网络服务节点标识符信息(例如,与CDF1121相关的标识符)以修改原接收的基于Diameter的CCR消息301。特别地,DSR104可将DBR信息的至少一部分(例如,一些或全部)插入原CCR消息301中,使得产生修改的CCR消息304。如图1所示,CCR消息301被修改,使得用户IP地址、IMPI和IMPU被添加到原会话标识符和包含于消息301中的用户名,这导致修改的CCR消息304。DSR104还可被配置为使用获得的网络服务节点标识符(即,包含于消息303中的CDF标识符)以将消息204寻址和路由到CDF1121。DBR信息还可包含第二会话标识符(例如,“会话ID_2”)和第二网络服务节点标识符/身份(例如,“PCRF_1”)。通过向第一网络服务节点即CDF1121提供第二网络服务节点和会话信息,本主题预空闲地向CDF1121提供已知的网络服务节点信息,使得CDF1121不需要询问第三方节点或数据库CDF1121是否需要与处理与移动订户相关的其它Diameter信令消息的其它网络服务节点通信或者另外获其身份。在替代性实施例中,DSR104可产生包含DBR信息中的一些或全部的全新的CCR消息而不是修改原接收的CCR消息301。
图4是示出根据这里描述的主题的实施例的丰富多个Diameter信令消息的示例性的基于Diameter的消息序列图。如图4所示,DSR104接收包含移动订户相关信息的Diameter信令消息即信用控制请求(CCR)消息401。在本例子中,移动订户相关信息包含用户名(例如,“用户名X”)和会话标识符(例如,“会话ID_1”)。在一个实施例中,会话标识符用作用于在发送CCR消息的节点与最终被选择/指定为处理CCR消息的网络服务节点之间建立的通信会话的标识符。
在接收CCR消息401之后,DBR104可被配置为产生DBR请求消息402。在一个实施例中,DSR104从接收的消息401提取一个或多个移动订户标识符,并且将提取的移动订户标识符中的一个或多个插入到产生的DBR请求消息中。在本例子中,DSR104从CCR消息401提取用户名标识符并随后产生DBR请求消息402。DSR104可然后在向DBR2发送请求消息之前将用户名标识符插入到产生的DBR请求消息402中。虽然DBR102在图4中被示为与DSR104共处,但是,在不背离本主题的范围的情况下,DBR102可被分开的独立的网络托管。
在接收DBR请求消息402时,DBR102使用包含于消息402中的用户名标识符以访问并交叉引用一个或多个绑定记录(例如,基于Diameter的绑定记录)。例如,在交叉引用用户名标识符(例如,“用户名X”)与存储于记录数据库128(在图1中示出)中的绑定记录之后,DBR102确定优选的用于处理与移动订户相关的CCR消息相关的网络服务节点是CDF1121。DBR102然后产生包含CDF1121的标识符或地址的DBR响应消息403。然后,DBR102向DSR104发送消息403。
在DBR响应消息403被DSR104接收之后,DSR104可然后将原CCR消息转送到在响应消息403中指定的网络服务节点。如图4所示,修改的CCR消息404(是修改的CCR消息401)被发送到CDF1121以供处理。
图4还示出DSR104随后接收包含与原移动订户相关的第二唯一会话标识符(例如,“会话ID_2”)、用户名(例如,“用户名X”)和IMS公共身份的Diameter消息A405。响应接收Diameter消息405,DBR104然后访问本地数据库(或图4所示的共处的DBR102)以确定优选的用于处理Diameter消息A405的网络服务节点。在一个实施例中,Diameter消息A405可包含另一CCR消息、ACR消息、ULR消息、Diameter可动管理消息或Diameter计费消息。虽然图4没有示出,但是DSR104可被配置为利用DBR请求消息(与上述的消息402类似)以询问DBR102确定优选的用于处理Diameter消息A405的网络服务节点。除了确定PCRF1141是优选的用于处理Diameter消息A405的网络服务节点(例如,通过交叉引用具有包含于绑定记录中的条目的用户名)以外,DBR102还可提供事先确定的网络服务节点识别信息和相关的会话标识符信息。例如,由于使用相同的用户名标识符“用户名X”以指定CDF1121作为优选的用于事先接收的CCR消息401的网络服务节点,因此DBR102可向DSR104提供第一会话标识符(即,“会话ID_1”)和第一网络服务节点标识符(即,识别CDF1121的“CDF_1”)。
在获取DBR信息之后,DSR104修改原Diameter消息405以包含第一会话标识符和第一网络服务节点标识符/身份。即,DSR104可修改原Diameter消息405以产生包含“会话ID_1”会话标识符和“服务CDF_1”标识符(识别CDF1121)的修改的Diameter消息A′406。DSR104可然后将修改的Diameter消息A′406路由到PCRF1141(由从DBR102获得的网络服务节点标识符识别)。
以类似的方式,图4示出在DSR104接收包含与原移动订户相关的第二唯一会话标识符(例如,“会话ID_3”)、用户名(例如,“用户名X”)和IMS私人身份的另一Diameter消息B407。响应接收Diameter消息407,DBR104然后访问本地数据库(或图4所示的共处的DBR102)以确定优选的用于处理Diameter消息B407的网络服务节点。在一个实施例中,Diameter消息B407可包含另一CCR消息、ACR消息、ULR消息、Diameter可动管理消息或Diameter计费消息。虽然图4没有示出,但是DSR104可被配置为利用DBR请求消息(与上述的消息402类似)以询问DBR102确定优选的用于处理Diameter消息B407的网络服务节点。除了被用于确定CSCF412是优选的用于处理Diameter消息B407的网络服务节点以外,DBR102还可提供事先确定的DBR信息,诸如网络服务节点识别信息、相关会话标识符信息和移动订户标识符信息。例如,由于使用相同的用户名标识符“用户名X”以指定CDF1121和PCRF1141分别是优选的用于事先接收的CCR消息401和Diameter消息A405的网络服务节点,因此DBR102可向DSR104提供第一会话标识符(即,“会话ID_1”)、第一网络服务节点标识符(即,识别CDF1121的“CDF_1”)、第二会话标识符(即,“会话ID_2”)和第二网络服务节点标识符(即,识别PCRF1141的“CDF_2”)。
在获取DBR信息之后,DSR104可被配置为修改原Diameter消息407以包含与移动订户相关的第一会话标识符、第一网络服务节点标识符/身份和IMPU标识符信息。特别地,DSR104可修改原Diameter消息407,以产生包含“会话ID_1”会话标识符、“服务CDF_1”标识符(识别CDF1121)和IMPU的修改的Diameter消息B′408。虽然图4没有示出,但是,DSR104还可在修改的Diameter消息B′408中包含第二会话标识符(例如,“会话ID_2”)和第二网络服务节点标识符(即,识别PCRF1141的“PCRF_1”)。DSR104可然后将修改的Diameter消息B′408路由到CSCF412(由从DBR102获得的网络服务节点标识符识别)。DSR104还可被配置为修改被确定为指向CDF以包含识别订户的服务PCRF的信息的接收Diameter信令消息。一般地,基于DBR查找的结果修改接收的Diameter信令消息以将关于第一类型的第一Diameter节点的Diameter绑定信息传送到与第一类型不同的第二类型的第二Diameter节点意在处于这里描述的主题的范围内。
图5是示出根据这里描述的主题的实施例的用于识别网络服务节点的绑定记录数据的示例性表500。在一个实施例中,表500可代表在DBR102中保持的数据库128的至少一部分。表300可包含作为列标题的多个移动订户相关标识符502~518。例如,表500可包含用于以下方面中的每一个的至少一个列:Diameter会话标识符502、用户名504、IMPI标识符508、IMPU标识符510、SIP URI512、NAI514、移动/可拨号516和用户IP地址518。表500还可包含诸如网络服务节点标识符/地址列520的网络服务节点列。虽然在图5中示出十个列,但表500可包含与任意类型的标识符相关的任意数量的列。
在一些实施例中,可在确定、识别和/或选择例如用于处理特定的Diameter交易或相关的Diameter消息的网络服务节点时使用绑定记录数据。例如,绑定记录数据可被用于将与由IMSI值识别的特定用户相关的交易路由到由HSS标识符识别的特定HSS。
图6是示出根据这里描述的主题的实施例的用于丰富Diameter信令消息的处理600的流程图。在块602中,接收与移动订户相关的Diameter信令消息。在一个实施例中,DSR104从发送的网络节点接收诸如CCR消息的基于Diameter的请求消息。
在块604中,从Diameter信念消息提取移动订户相关信息。在一个实施例中,DSR104被配置为从接收的CCR消息提取移动订户相关信息。例如,提取的移动订户相关信息可包含与特定的移动订户相关的用户名和会话标识符。
在块606中,询问DBR节点。在一个实施例中,DSR104可产生包含提取的移动订户相关信息的询问或请求消息(例如,DBR请求消息)。例如,DSR104可从接收的CCR消息提取与移动订户相关的用户名和会话标识符。DSR104可然后被配置为产生包含提取的用户名和会话标识符的请求或询问消息。DSR104还可被配置为向DBR102发送包含用户名和会话标识符的请求消息。
在块608中,DBR102中的绑定记录被访问以定位DBR信息。在一个实施例中,DBR102可比较或交叉引用接收的DBR询问消息中的用户名标识符与包含于存储于记录数据库128中的绑定记录中的要素(例如,标识符/参数)。在找到绑定记录中的匹配要素/条目之后,DBR102产生DBR回答消息。DBR102还可被配置为在记录绑定中插入与匹配要素对应的附加的DBR信息。例如,除了其它的移动订户标识符、网络服务节点标识符和会话标识符以外,DBR信息可包含与移动订户相关的网络服务节点。并且,如果存在不匹配包含于现有的绑定记录中的要素的任何移动订户相关标识符,那么可添加这些不匹配的移动订户相关标识符(即,提供给现有的绑定记录)。
在块610中,在DBR上接收DBR信息。在一个实施例中,DSR104接收包含DBR信息的DBR响应消息。
在块612中,DBR用DBR信息修改/丰富Diameter信令消息。在一个实施例中,DSR104通过插入接收的DBR信息的至少一部分修改原接收的Diameter信令消息(即,在块602中接收的消息)。
在块614中,向着选择/指定的网络服务节点路由修改的Diameter信令消息。在一个实施例中,DSR104将修改的Diameter信令消息(例如,CCR消息)路由到与由DBR102提供的网络服务节点标识符相关的网络服务节点。例如,DSR104可将修改的CCR消息转送到CDF1121。
