优先权要求
本申请要求于2010年12月23日递交的美国临时专利申请序列号为61/426,841的权益,该临时申请的公开内容通过引用而全部被并入本文。
技术领域
本文描述的主题涉及处理要发往计费功能节点的Diameter信令消息。更具体地,该主题涉及用于修改要发往计费功能节点的Diameter信令消息的方法、系统和计算机可读介质。
背景技术
目前,在线计费系统(OCS)使得电信服务供应商对顾客的服务使用进行实时计费。在线计费系统可以采用基于流的计费算法和过滤器来确定用户对于服务数据流的计费。例如,提供的OCS算法利用包含于所接收到的基于Diameter的信令消息(如信用控制请求(CCR)消息)中的信息,来确定移动用户使用在线服务所引起的合理计费。在OCS处接收到的CCR消息通常包含有限量的信息,因此限制了将与用户有关的数据用作输入的算法的有效性。显著地,如果将与移动用户有关的额外数据提供给OCS,则能够实施更复杂的OCS算法来对客户更有效地计费。
相应地,存在改善用于修改要发往计费功能节点的Diameter信令消息的方法、系统和计算机可读介质的需求。

具体实施方式
本文描述的主题包括用于修改要发往计费功能节点的Diameter信令的方法、系统和计算机可读介质。虽然本主题在此被描述为在Diameter信令路由器(DSR)处实施,但是可以使用被配置成路由Diameter消息(例如,Diameter路由代理(DRA)、Diameter委托代理(DPA)、Diameter中继代理或者Diameter转换代理)的任何节点,而不偏离本主题的范围。在一个实施例中,DSR接收要发往计费功能节点的基于Diameter的信令消息,所述计费功能节点例如是在线计费系统(OCS)节点或离线计费系统(OFCS)节点。接收到的Diameter信令消息可能从另一网络元件被发送,比如信令传送点(STP)或移动管理实体(MME)。在接收Diameter信令消息时,DSR可能被配置为在转发修改后的消息到计费功能节点之前将与移动用户有关的信息增加到消息上。可以从本地或远程数据库访问或获得与移动用户有关的信息,所述数据库已经提供有来自之前接收到的信令消息的与移动用户有关的信息。
图1描绘了示例性系统100,其包括数个多种移动网络元件,所述元件可用于修改要发往计费功能节点的Diameter信令消息。在一个实施例中,系统100包括信令传送点(STP)102,其被配置为路由7号信令系统(SS7)信令消息,比如移动应用部分(MAP)消息。在一个实施例中,STP102可能被配置为从由网络节点发送的接收到的MAP更新位置请求消息和MAP更新通用分组无线业务(GPRS)位置请求消息中提取/复制与移动用户有关的信息,比如移动用户识别信息(例如,IMSI、电话簿号码和GUTI信息)。例如,发送网络节点可以包括支持移动用户设备101(例如移动电话)的移动用户中心(MSC)109或者GPRS服务支持节点(SGSN)110。STP102还可以被配置为从接收到的MAP信令消息中提取和/或复制与移动用户有关的信息,例如服务网络信息,如服务MSC地址信息、拜访位置寄存器(VLR)号码信息、SGSN地址信息以及SGSN号码信息。
在一个实施例中,在STP102处复制的与移动用户有关的信息(例如,服务网络信息)被传递到Diameter路由节点,比如Diameter信令路由器(DSR)104。DSR104还可以被配置为存储/高速缓存由STP104提供的服务网络信息。例如,STP102(或者与STP102相关联的应用或子系统)可能被配置为向DSR104发送未经请求的更新或者通知信令消息,其包括与移动用户相关联的复制服务网络信息。然后,DSR104可能将接收到的服务网络信息存储到本地高速缓存或数据库108中。在替代实施例中,DSR104可以向STP102(或者与STP102相关联的应用或子系统)发送查询消息以请求与移动用户有关的信息,比如服务MSC地址、VLR号码、SGSN地址、SGSN号码信息、或者与移动用户有关的任何其它服务网络信息。DSR104还可以发送查询消息。
在一个实施例中,DSR104可以将服务网络信息转换成可以由其他网络节点利用的PLMN相关的标识符。例如,DSR104可以将服务MSC地址、VLR号码、SGSN地址、SGSN号码信息转换成相关联且适当格式化的移动国家码(MCC)和移动网络码(MNC)标识符,这些标识符由其他网络节点在长期演进(LTE)网络中识别出,比如计费功能节点,如在线计费系统(OCS)节点116。在一个实施例中,OCS节点116可以利用MCC和MNC信息响应由策略和计费执行功能(PCEF)节点(如,PCEF112)发送的信用控制请求(CCR)消息。正如在此使用的,术语“在线计费”是指实时管理由网络计费功能节点(比如OCS节点116)引导的定价和付款过程。在线计费系统知道每个移动用户实时的服务使用和账户结余。在一个实施例中,OCS节点116可以被配置为基于用户使用和当前结余为每个移动用户定制定价、服务交付和营销传播。虽然图1描绘了OCS节点116,但可以在不偏离本主题的范围的情况下使用其他计费功能节点,比如离线计费系统(OFCS)节点。
在一个实施例中,OCS节点116被配置为管理所有用户类型和服务类型,并为网络服务供应商提供用于移动用户所使用的任意网络服务的在线计费和在线控制能力。OCS节点116可以被供应有包括各种计费规则和服务流过滤器的算法。服务流过滤器识别并处理与特定服务数据流相关联的分组。基于与用户相关的信息(例如,移动用户标识符,拜访网络识别信息,等等),在OCS节点116中的OCS算法可以使用计费规则来确定如何对移动用户为给定服务计费(例如,在单个PDP上下文中为独特的媒体流计费)。在一个实施例中,OCS节点116可以接收来自PCEF节点112的基于Diameter的请求消息。例如,PCEF节点112可以发送信用控制请求(CCR)消息来请求与移动用户有关的计费规则。在另一个实施例中,OCS节点116可以与能够进行在线计费的IMS网络节点(例如,应用服务器、媒体资源功能控制器(MRFC)以及经由IMS网关114的服务呼叫会话控制功能(S-CSCF))传递信用控制请求和应答。
在一个实施例中,DSR104可以将MCC和MNC标识符信息,或者任何其他服务网络信息存储在与DSR104集成或可以访问DSR104的本地高速缓存或数据库108中。在另一个实施例中,DSR104可以将与移动用户有关的信息(例如,用户标识符信息和/或服务网络信息)传递到用户简档存储库(SPR)节点122(或一些其他的数据库应用或数据库存储库),其中存储有当前MCC/MNC信息以及移动用户信息。DSR104还可以被配置为稍后查询SPR节点122来获得存储的服务网络信息。
在一个实施例中,DSR104被配置为在各种Diameter接口上的各种Diameter节点之间路由Diameter消息,所述接口包括但不限于Gy、Ro、Rf和S6a接口。DSR104进一步配置为监控在PCEF节点(比如网关GPRS支持节点(GGSN)、公共数据网络(PDN)网关等等)和OCS节点116之间经由Gy接口进行通信的Diameter信令消息流量。在一个实施例中,DSR104被配置为监控、观测和/或截取从PCEF112发送到OCS节点116的Gy接口信令消息,比如与用户相关联的Diameter信用控制请求(CCR)消息。DCR104还可以被配置为修改Diameter CCR消息以包括以下的一个或多个:服务MSC地址、VLR号码、SGSN地址、SGSN号码、MCC标识符或MNC标识符信息。然后,修改的CCR消息被路由到目标OCS节点116。
在替换实施例中,DSR104被配置为监控经由S6a接口在移动管理实体(MME)111和归属用户服务器(HSS)106之间通信的Diameter信令消息流量,并从Diameter信令消息(例如更新位置请求消息)中提取识别移动用户以及与当前PLMN服务移动设备101相关联的MCC和MNC信息的信息。
图2到图7示出了利用图1描绘的网络元件用于修改要发往计费功能的Diameter信令消息的各种示例性消息序列。例如,图2为示出根据本文描述的主题的实施例的在网络路由节点处从更新位置请求(ULR)信令消息获得服务网络信息的过程的消息序列图。在图2中,MSC109可以将SS7MAP更新位置请求信令消息201(该消息最初从如便携式电话的移动用户设备处接收)转发给网络路由节点,比如STP102。在一个实施例中,SS7MAP更新位置请求消息可以包括比如国际移动用户身份(IMSI)信息和/或电话簿号码(DN)信息的移动用户识别信息、位置信息(例如,服务位置区域代码信息、服务小区识别信息、比如全球定位系统坐标信息的移动用户地理位置坐标信息,等等),以及可以与服务/支持与移动用户相关联的移动设备的服务网络元件相对应的服务网络信息。示例性服务网络信息可以包括包含于更新位置请求信令消息201中的服务网络元件识别信息,比如服务MSC地址和/或与移动用户相关联的拜访位置寄存器(VLR)号码。
在替代实施例中,信令消息201反而可以包括来自SGSN110的SS7MAP更新GPRS位置信令消息。从SGSN110发送的SS7MAP更新GPRS位置请求信令消息还可以包括移动用户识别信息、位置信息和服务网络元件识别信息,比如服务SGSN地址和/或SGSN号码。
在接收到更新位置请求信令消息201之后,STP102可以从更新位置请求消息201获得移动用户识别信息和服务网络信息。STP102然后可以复制和/或高速缓存服务网络信息(例如,与由移动用户访问的网络相关联的MSC和VLR号码)和/或从MAP更新位置消息中获得的位置信息。在替代实施例中,STP102可以被配置为接收MAP更新GPRS位置请求消息,并可以在更新位置请求消息被路由到HLR102或HSS106之前,从信令消息中提取并存储SGSN号码信息。图2进一步描绘了STP102将用户状态更新通知消息203传输给DSR104。例如,消息203可以包括移动用户识别信息(例如,IMSI识别信息或DN识别信息),位置信息和服务网络信息(即,服务网络元件识别信息),比如服务MSC地址信息和/或VLR号码。在替代实施例中,消息203可以包括服务SGSN地址和/或SGSN号码。
在从STP102接收服务网络信息时,DSR104可以将MSC地址和VLR号码信息转换成适当格式化的移动国家码(MCC)和移动网络码(MNC)识别信息。MCC和MNC数据可以被DSR104存储在本地数据库108中供以后使用。例如,图3示出了描绘在Diameter外出节点(例如DSR104)使用上述提到的存储的MCC和MNC数据修改Diameter信令消息的消息序列图。在图3中,PCEF112可以将与移动用户相关联的Diameter信令消息发送到DSR104。在一个实施例中,PCEF112可以是GGSN或PDN网关。在图3中,Diameter信令消息是信用控制请求(CCR)消息301,其包含移动用户标识符(例如IMSI或DN),所述消息可以由DSR104经由Gy接口、Ro接口或Rf接口来接收/截取。
在一个实施例中,DSR104可以识别或检测CCR消息301,并修改CCR消息301以包括拜访MCC和MNC标识符信息和/或位置信息。显著地,MCC和MNC标识符数据可以源自于或包括之前获得(见图2)并存储在数据库108中的信息。DSR102可以被配置为经由Gy接口、Ro接口或Rf接口将修改后的CCR消息302路由到OCS节点116。在接收到修改后的CCR消息302之后,OCS节点116可以利用包含在消息302中的用户标识符和拜访MCC和MNC信息来生成信用控制应答(CCA)消息303。然后,CCA消息303可以由OCS节点116发送到起源PCEF112。在替代实施例中,IMS网关114和/或S-CSCF可以取代PCEF节点而用于通过在Ro接口上发送CCR消息301来与DSR104进行通信。在另一个实施例中,IMS网关功能或S-CSCF可以取代PCEF节点而用于通过在Ro接口上发送CCR消息301来与DSR104进行通信。在另一个实施例中,GGSN、PDN网关或CSCF可以取代PCEF节点112而用于通过在Gx/Rx接口上发送CCR消息301来与DSR104进行通信。在这样的实施例中,DSR104可以被配置为经由Gx/Rx接口取代OCS节点116将修改后的CCR消息302路由到PCRF118。在替代实施例中,起源PCRF节点可以取代PCEF节点112而用于通过在S9接口上发送CCR消息301来与DSR104进行通信。在这样的实施例中,DSR104可以被配置为经由S9接口取代OCS节点116将修改后的CCR消息302路由到目标PCRF。
图4示出了描绘根据本文描述的主题的实施例的修改要发往计费功能节点的Diameter信令消息的过程的消息序列图。在图4中,MME111将S6a更新位置请求(ULR)信令消息401发送给比如DSR104的Diameter路由节点。在一个实施例中,S6a ULR消息401可以包括移动用户识别信息,比如IMSI信息、DN信息和/或全局唯一临时标识符(GUTI)信息。S6a ULR消息401还可以包括拜访MCC和MNC信息,所述MCC和MNC信息对应于服务/支持与用户以及位置信息(例如,跟踪区域信息、服务小区识别信息、全球定位系统坐标信息,等)相关联的漫游移动设备的PLMN。在接收ULR消息401时,DSR104可以复制和/或高速缓存(在本地数据库108中)来自消息401的拜访MCC和MNC和/或位置信息。之后,ULR消息402然后可以被转发给原始目标,HSS106。在接收到ULR消息402(也就是被转发的消息401)以后,HSS106然后可以响应于由MME111以S6a更新位置应答(ULA)消息403做出的原始更新位置请求。
一旦拜访MCC和MNC和/或位置信息被存储在本地数据库108中,PCEF112可以经由Gy或Ro接口将包含用户标识符的CRR消息404要发往OCS节点116。DSR104然后可以识别/检测CRR消息404,并确定包含于CCR消息404中的移动用户标识符是否与之前高速缓存的MCC和MNC和/或从消息401中复制的位置信息相关联。DSR104然后可以修改CCR消息404以包括拜访MCC和MNC信息。在一个实施例中,DSR104然后可以经由Gy或Ro接口将修改后的CCR消息405发送给OCS节点116。在接收修改后的CCR消息405时,OCS节点116可以将CCA消息406发送给PCEF112作为对原始CCR消息404的响应。
图5为示出根据本文描述的主题的实施例的更新具有服务网络信息的用户简档存储库(SPR)节点的消息序列图。例如,MME111将S6a更新位置请求(ULR)信令消息501发送到比如DSR104的Diameter路由节点。在一个实施例中,S6a ULR消息501可以包括移动用户识别信息,比如IMSI信息、DN信息和/或GUTI信息和/或位置信息。S6a ULR消息501还可以包括对应于服务/支持与移动用户相关联的漫游移动设备的PLMN的拜访MCC和MNC信息。在接收ULR消息501时,DSR104可以从消息501中复制拜访MCC和MNC和/或位置信息。然后可以将ULR消息501转发(即,图5所示的消息502)到其原始目标,HSS106。在接收到ULR消息502之后,HSS106然后可以通过发送S6a更新位置应答(ULA)消息503响应MME111的原始请求。在一个实施例中,DSR104还可以截取ULA消息503,并提取包含于其中的与移动用户有关的信息。DSR104然后可以将所提取的与移动用户有关的信息存储到本地高速缓存或SPR122中。
在从ULR消息501复制拜访MCC和MNC和/或位置信息之后的一段时间中,DSR104可以生成SPR更新消息504。在一个实施例中,SPR更新消息504包括移动用户识别消息(例如,IMSI、DN和/或GUTI信息)和之前复制的拜访MCC和MNC和/或位置信息。在一个实施例中,DSR104可以经由Sp接口或轻量目录访问协议(LDAP)接口将SPR更新消息504发送到SPR122中。
图6示出了描绘使用之前存储在SPR122的MCC和MNC和/或位置信息在DSR104处修改要发往计费功能节点的Diameter信令消息的过程的消息序列图。在图6中,PCEF112可以将Diameter信令消息601发送到DSR104。在一个实施例中,替代PCEF112,IMS网关功能可以负责发送Diameter信令消息601。在图6中,Diameter信令消息601是信用控制请求(CCR)消息,其包含要发往OCS节点116的移动用户标识符。图6中描绘的CCR消息601可以经由Gy接口或Ro接口由DSR104接收/截取。在一个实施例中,DSR104可以识别或检测包含与存储在SPR122中的MCC和MNC和/或位置信息相关联的移动用户标识符的CCR消息601。DSR104然后可以被配置为经由Sp接口或LDAP接口将SPR查询消息602发送到SPR节点122。在一个实施例中,SPR查询消息602可以包括用户识别信息,比如IMSI、DN和/或GUTI信息。在接收查询消息602时,SPR122生成SPR应答消息604,其包括与前面提到的用户识别信息相关联的拜访MCC和MNC和/或位置信息。在一个实施例中,SPR应答消息604被发送到DSR104,所述DSR104然后可以被配置为修改CCR消息601以包括之前存储在SPR节点122中的拜访MCC和MNC标识符和/或位置信息。DSR102可以被配置为随后经由Gy接口或Ro接口将修改后的CCR消息606路由到OCS节点116。在接收到修改后的CCR消息606之后,OCS节点116然后可以利用消息302中的用户标识符和拜访MCC和MNC和/或位置信息来生成信用控制应答(CCA)消息608。CCA消息608然后可以被OCS节点116发送到起源PCEF112。在替代实施例中,IMS网关功能114可以替代PCEF112而用于通过在Gy或Ro接口上发送CCR消息601与DSR104进行通信。
图7示出了描绘使用之前存储在数据库108中的MCC和MNC数据在DSR104处修改要发往计费功能节点的Diameter消息的过程的消息序列图。在图7中,第一Diameter节点704可以经由DSR104将Diameter信令消息701要发往第二Diameter节点705。在一个实施例中,第一Diameter节点704可以为如下的至少一个:Diameter信令路由器(DSR)、Diameter路由代理(DRA)、Diameter委托代理(DPA)和Diameter中继代理。在图7中,Diameter消息701包括用户名属性值对(AVP)和修饰的网络访问标识符(NAI)。Diameter信令消息701可以被DSR104接收或截取。在一个实施例中,DSR104可以识别或检测Diameter信令消息701,并随后复制从用户名AVP的修饰的NAI部件中获得的MCC和MNC消息。例如,复制的MCC和MNC信息可以存储在数据库108中。或者,MCC和MNC信息可以被存储在SPR节点122中。
在一个实施例中,DSR104将Diameter信令消息702转发给第二Diameter节点705。在存储MCC和MNC信息之后,DSR生成SPR更新消息703,其包括用户标识符信息(例如,IMSI、DN和/或GUTI信息)以及拜访MCC和MNC信息。在一个实施例中,SPR更新信息703经由Sp接口或LDAP接口被发送给SPR122。DSR104可以发出如图6所示的SPR请求消息,以便获得与特定的用户标识符相关联的拜访MCC和MNC信息来修改Diameter信令消息,比如随后的CCR请求消息。

在方框804中,访问与移动用户有关的信息。在一个实施例中,DSR104访问之前获得并高速缓存的与移动用户有关的信息。例如,DSR104可以访问本地高速缓存108以获得之前存储的与移动用户有关的信息(例如,拜访MCC和MNC和/或位置信息)。相似地,DSR104可以将查询消息发送到外部数据库存储节点(例如,HSS106或SPR122)或者信令路由节点(例如STP102),以请求与移动用户有关的信息。在另一个实施例中,DSR104可以截取由HSS106发送的、包含与移动用户有关的信息的信令消息。
在方框806中,Diameter信令消息被修改以包括与移动用户相关的信息。在一个实施例中,DSR104被配置成将所获得的/访问的与移动用户有关的信息(比如拜访MCC和MNC和/或位置信息)插入到接收到的Diameter信令消息(比如CCR消息)中。
在方框808中,修改后的Diameter信令消息被路由到目标计费功能节点。在一个实施例中,DSR104被配置为将包含插入的与移动用户有关的信息的修改后的CCR消息路由到原始目标,也就是计费功能节点(例如,OCS或OFS)。
