Description
本申请要求于2015年11月16日提交中国专利局、申请号为201510786144.9,发明名称为“漫游计费方法、相关装置及在线计费系统”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本发明涉及移动通信技术领域,具体而言涉及一种漫游场景下的计费方法、相关装置及在线计费系统。
漫游(roaming)指移动台离开自己注册登记的服务区域,移动到另一服务区后,移动通信系统仍可向其提供服务的功能。欧洲漫游法案III定义了可选择的漫游服务提供商(Alternative Roaming Provider,ARP),一个ARP可以为一个或者多个欧洲国家的用户提供数据业务漫游服务器。用户在欧洲内漫游时,可以选择普通漫游,即通过与用户归属地服务提供商(服务提供商简称运营商)签订协议的本地服务提供商来提供服务。用户还可以选择ARP提供漫游服务,向ARP订购相应的ARP套餐。相对于普通漫游,ARP漫游可以提供更低的资费,欢迎程度更高。
参见图1,图1是现有技术提供的计费方法的流程图。
其中,用户当前漫游到ARP网络,ARP网络的网元包括ARP计费系统,例如在线计费系统(Online Charging System,OCS)、ARP代理(ARP Proxy)和拜访地的(Visit)服务GPRS支持节点(Serving GPRS Support Node,SGSN),归属地网络(Home network)的网元包括归属地的在线计费系统(Home OCS)、归属地的策略控制规则功能(Policy Control Rule Function,PCRF)设备以及归属地的网关GPRS支持节点(Gateway GPRS Support Node,GGSN)。
具体的,ARP OCS用于根据用户订购的ARP套餐对用户进行计费。ARP OCS还可以获取用户的ARP套餐使用量或账户余额,并通过Sy接口发送给Home PCRF设备(Home PCRF设备简称PCRF)。ARP代理作为ARP OCS的代理,用于将其他网元发送的消息转发给ARP OCS或将ARP OCS发送的消息向外转发。
当用户准备在拜访地使用数据业务时,漫游用户的移动台向拜访地的SGSN发送分组数据协议(Packet Data Protocol,PDP)连接请求,请求建立PDP会话。拜访地的SGSN将该连接请求转发到用户归属地的GGSN。
图1所示的计费方法包括如下流程:
步骤1、归属地的GGSN向归属地的PCRF设备发送信用控制请求消息。
其中,信用控制请求(Credit Control Request,CCR)消息的目的在于请求针对该用户的计费控制策略,该消息可以通过Gx接口发送。
PCRF设备根据该CCR消息对该用户进行策略决策,策略决策过程具体包括步骤2和6。
步骤2、PCRF确定该用户该订购了ARP套餐,向ARP代理发送请求消息获取该套餐的使用量。
其中,PCRF上保存了用户的ARP订购信息,PCRF可以根据该信用控制请求确定用户订购了ARP套餐。
PCRF通过消费限额请求(Spending Limit Request,SLR)消息向ARP OCS获取该套餐的使用量,该消息可以通过Sy接口发送。
步骤3、ARP代理转发该SLR消息到ARP OCS。
步骤4、ARP OCS获取该ARP套餐的使用量,并回消费限额响应(Spending Limit Answer,SLA)消息给ARP Proxy。
步骤5、ARP代理转发该SLA消息到PCRF。
步骤6、PCRF根据SLA消息中的套餐使用量对用户进行策略控制,生成相应的控制策略,并通过信用控制响应(Credit Control Answer,CCA)消息下发给归属地的GGSN。
步骤7、归属地的GGSN根据下发的控制策略,向ARP代理申请信用授权。
其中,GGSN可以通过Gx接口发送CCR消息来申请信用授权。
步骤8、ARP代理转发CCR消息到ARP OCS。
步骤9、ARP OCS对用户进行信用授权,返回CCA消息,其中携带用户的授权配额(quota)。
步骤10、ARP代理转发CCA消息给GGSN。
此时,PDP会话建立成功,用户开始使用ARP套餐中的数据业务。
随着技术的发展,归属地的OCS逐渐演进为融合的OCS,即OCS中融合了传统的PCRF的功能,传统的PCRF演进为嵌入式(embedded)PCRF,嵌入
式PCRF作为一个模块嵌入到OCS中,嵌入式PCRF不执行具体的策略决策功能,策略决策功能具体由OCS中的融合计费点(Convergent Billing Point,CBP)来实现。
现有技术中的漫游计费方法需要归属地的PCRF向ARP OCS获取ARP套餐的使用量,但融合的OCS中的CBP和ARP OCS之间无通信接口,因而CBP无法向ARP OCS获取该ARP套餐的使用量,进而CBP无法对ARP漫游业务进行策略决策,导致漫游用户无法使用订购的ARP套餐。

下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性的劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明提供一种漫游计费方法、装置及计费系统,参见图2,图2是本发明实施例提供的计费系统的组网示意图。
其中,ARP网络的网元包括ARP计费系统、ARP代理、客户关系管理(Customer Relationship Management,CRM)系统和拜访地的SGSN。其中,拜访地的SGSN的功能也可以由移动性管理实体(Mobile Management Entity,MME)来实现。ARP计费系统可以为在线计费系统,也可以为离线计费系统。归属地网络的网元包括归属地的OCS以及归属地的网关GPRS支持节点(Gateway GPRS Support Node,GGSN)。归属地的GGSN的功能也可以由分组数据网关(Packed Gateway,PGW)来实现。归属地的GGSN在本发明实施例中简称GGSN,拜访地的SGSN简称为SGSN。
在本发明实施例中,归属地的OCS采用融合的OCS技术,其中融合了嵌入式PCRF,嵌入式PCRF在本发明实施例中简称PCRF。归属地OCS还包括CBP,CBP可以接收外部的计费请求,根据计费请求执行在线计费或离线计费。CBP和嵌入式PCRF之间采用扩展的(Extensional Sy,Esy)接口进行通信。嵌入式PCRF和归属地的GGSN之间采用Gx接口进行通信,归属地的GGSN和CBP、ARP OCS之间均采用Gy接口进行通信,ARP的代理和嵌入式PCRF之间采用Sy接口进行通信。相对于现有技术中OCS和PCRF分离部署的场景,本发明实施例中的融合的OCS的场景中,运营商的产品信息和用户订购信息可
以只在CBP上定义,有利于产品的维护和运营。
如图所示,用户访问ARP网络的CRM系统,订购合适的ARP套餐。ARP网络的CRM还将用户的订购信息同步到ARP网络的OCS以及用户归属地的OCS。其中,订购信息包括订购的用户以及订购的业务量,ARP网络的CRM具体通过ARP代理将上述订购信息同步到归属地的OCS。
参见图3,图3是本发明实施例一提供的漫游计费方法的流程图。
用户漫游到拜访地时,准备通过拜访地的网络使用业务,拜访地的SGSN向该用户归属地的GGSN发送PDP建立请求,归属地的GGSN中的策略和计费执行功能(Policy and Charging Enforcement Function,PCEF)设备(PCEF设备简称PCEF)向嵌入式PCRF发送信用控制请求CCR消息,用于请求该用户的控制策略。
本发明实施例提供的漫游计费方法包括如下步骤:
步骤301、嵌入式PCRF接收PCEF发送的信用控制请求CCR消息,该CCR消息中携带用户的位置信息。
具体的,用户归属地的嵌入式PCRF通过Gx接口接收PCEF发送的CCR消息。
步骤302、嵌入式PCRF向CBP发送第一控制策略请求消息,该控制策略请求消息中携带用户的当前位置信息。
具体的,嵌入式PCRF上没有存储用户的订购信息,因而PCRF向CBP发送该控制策略请求消息来请求该用户的控制策略。其中,第一控制策略请求消息在具体实现时可以为消费限额请求SLR消息,该消息通过Sy接口传递。
步骤303、嵌入式PCRF接收该CBP返回的第一控制策略响应消息,该第一控制策略响应消息中携带所述用户的ARP订购信息。
其中,第一控制策略响应消息在具体实现时可以为SLA消息,该消息通过Sy接口传递。
步骤304、嵌入式PCRF根据该订购信息向ARP OCS发送使用量请求消息,所述使用量请求消息中携带所述用户的ARP订购信息。
具体的,由于用户的ARP套餐使用量信息存储在ARP OCS上,因而PCRF向ARP OCS发送使用量请求消息。需要说明的是,由于ARP代理是ARP OCS的代理设备,PCRF也可以向ARP代理发送使用量请求消息,由ARP代理将该消息转发给ARP OCS。
步骤305、嵌入式PCRF接收ARP OCS返回的使用量响应消息,所述使用量响应消息中携带所述用户的ARP套餐使用量。
其中,ARP套餐使用量可以为数据流量、数据时长,还可以为也用或不可用,即可用表示ARP套餐还有剩余,不可用表示ARP套餐使用完毕。
步骤306、嵌入式PCRF根据所述ARP套餐使用量对所述用户生成控制策略,并通过第一控制策略响应消息向所述PCEF发送生成的控制策略。
具体的,嵌入式PCRF根据所述ARP套餐使用量对用户进行策略决策,即对用户生成控制策略,并向PCEF发送该控制策略。其中,控制策略中可以包括服务质量(Quantity of Service,Qos)信息和计费规则等。
在本发明实施例提供的漫游计费方法中,嵌入式PCRF向CBP获取用户的ARP订购信息,以及向ARP OCS获取该用户的ARP套餐使用量,然后PCRF根据ARP套餐使用量对用户进行策略决策。随后归属地的PCEF根据PCRF下发的控制策略对用户进行策略控制,用户即可开始使用ARP套餐的业务量。与现有技术相比,本发明实施例提供的漫游计费方法可以适用于融合的OCS场景下的计费,适应性较好。
在本发明实施例中,PCEF根据PCRF发送的控制策略对用户进行策略控制,由于该控制策略是基于ARP套餐生成的,因而PCEF将向ARP OCS请求信用配额,并根据ARP OCS返回的信用配额对用户进行计费控制。ARP OCS在计费过程中,可能出现ARP套餐使用完毕,或状态异常的情况(例如无法扣费)。此时,本发明实施例提供的计费方法还包括如下步骤307-308:
步骤307,嵌入式PCRF接收ARP计费系统发送的套餐使用状态消息,所述套餐使用状态消息中携带所述用户的ARP套餐的使用状态。
其中,ARP套餐的使用状态可以包括ARP套餐使用完毕、状态异常或状态正常等类型。
步骤308、嵌入式PCRF向所述CBP发送第二控制策略请求消息,所述第二控制策略请求消息中携带所述ARP套餐的使用状态。
具体的,PCRF通过Sy接口再次向CBP发送SLR消息,该SLR消息中携带ARP套餐的使用状态,以便于CBP获知ARP套餐的使用状态,并根据该套餐的使用状态对用户进行策略决策,例如在ARP套餐使用完毕,或状态异常时,根据归属地套餐对该用户生成新的控制策略或强制用户下线等。若CBP对该用户生成新的控制策略,则本发明实施例还包括如下步骤309-310:
步骤309、嵌入式PCRF接收所述CBP返回的第二控制策略响应消息,所述第二控制策略响应消息中携带所述用户的归属套餐控制策略。
其中,第二控制策略响应消息为SLA消息,该消息中携带新的控制策略,例如用户的归属套餐控制策略。
步骤310、嵌入式PCRF向所述PCEF发送重鉴权请求RAR消息,所述RAR消息中携带所述用户的归属套餐控制策略。
本发明实施例中,嵌入式PCRF在SLA消息中携带新的控制策略时,向PCEF发送重鉴权请求(Re-Auth-Request,RAR)。其中,RAR消息中可以携带用户的归属套餐控制策略。
PCRF向PCEF发送RAR消息可以使得PCEF更新用户的控制策略,进而PCEF根据新的归属套餐控制策略对用户进行策略控制,用户的业务不会因为ARP套餐使用完毕或状态异常而中断,增强了用户的业务体验。
以上对嵌入式PCRF一侧的计费流程进行了描述,下面描述CBP一侧的漫游计费流程。参见图4,图4是本发明实施例二提供的漫游计费方法的流程图。
用户漫游到拜访地时,本发明实施例提供的漫游计费方法包括:
步骤401、CBP接收嵌入式PCRF发送的第一控制策略请求消息,该第一控制策略请求消息中携带用户的位置信息。
具体的,第一控制策略请求消息用于请求用户的控制策略,该消息中携带用户的标识以及用户的当前位置信息。第一控制策略响应消息在具体实现时可以为SLR消息,该消息通过Sy接口传递。
步骤402、CBP根据所述位置信息确定用户订购了ARP套餐,向PCRF发送控制策略响应消息,该控制策略响应消息中携带所述用户的ARP订购信息。
具体的,CBP可以判断所述用户的位置信息与本地保存的ARP套餐中的位置信息是否一致,若一致,则说明用户订购了该位置的ARP套餐,CBP通过ESy接口向PCRF发送第一控制策略响应消息,其中携带用户的ARP订购信息。
在本发明实施例提供的漫游计费方法中,CBP在接收到PCRF发送的控制策略请求消息后,确定用户订购了ARP套餐,则向PCRF发送携带所述ARP订购信息的控制策略响应消息,以便于PCRF根据该ARP订购信息对用户进行策略决策,进而实现基于ARP套餐的漫游计费。与现有技术相比,本发明实施例使得ARP订购信息可以保存在CBP上,而不需要将普通订购信息(例如归
属地套餐订购信息)和ARP订购信息分别保存在CBP和嵌入式PCRF上,可以方便运营商在CBP上统一管理用户的业务订购信息,提高运营效率。
在本发明实施例中,若CBP判断用户没有订购当前位置信息对应的ARP套餐,则CBP根据普通订购信息,例如用户归属地的套餐对用户进行策略决策并生成控制策略,向PCRF下发该控制策略,从而实现基于普通订购信息的计费。
进一步的,用户在使用ARP套餐的过程中,可能出现ARP套餐使用完毕或ARP套餐的状态异常(例如ARP计费系统扣费失败)的情况,则PCRF向CBP上报ARP套餐的使用状态,则本发明实施例提供的计费方法还包括:
步骤403、CBP接收所述嵌入式PCRF设备发送的第二控制策略请求消息,所述第二控制策略请求消息中携带所述用户的ARP套餐的使用状态。
具体的,第二控制策略请求消息在具体实现时可以为SLR消息,该SLR消息中携带用户的ARP套餐的使用状态。
步骤404、在使用状态为ARP套餐使用完毕或状态异常时,CBP根据所述用户的归属套餐对所述用户生成归属套餐控制策略并向所述嵌入式PCRF发送。
在本发明实施例中,若ARP套餐的使用状态为ARP套餐使用完毕或状态异常,则需要为用户提供新的计费套餐。本实施例中CBP根据所述用户的归属套餐生成归属套餐控制策略并向所述嵌入式PCRF发送,进而PCRF将该归属套餐控制策略发送给PCEF,使得PCEF根据该归属套餐控制策略对用户进行策略控制,不会中断用户的业务使用,例如数据业务使用。
参见图5-6,图5-6是本发明实施例三提供的漫游计费方法的流程图。
在本发明实施例中,挪威用户在德国漫游,并订购了Germany ARP套餐包,10欧元包100M流量,带宽为512kbps。当该套餐使用完毕后,使用归属地(挪威)的漫游套餐,例如0.001欧元/Kb,带宽为128kbps。
如图所示,本发明实施例提供的漫游计费方法包括如下步骤:
501、挪威用户在德国漫游上网,Germany SGSN向Norway GGSN发起PDP会话建立请求,Norway GGSN发起Gx CCR请求到Embedded PCRF申请控制策略。
502、Embedded PCRF发起Esy SLR消息到CBP进行策略申请,CBP根据Esy SLR中携带的用户位置信息查询用户ARP订购记录,并且获取到对应漫游
地的ARP套餐信息。
其中,Esy SLR请求消息里面包含如下AVP取值:
