Description

一种配额共享方法及信令路由设备
本申请要求于2016年4月25日提交中国专利局、申请号为201610263752.6、发明名称为“一种配额共享方法及信令路由设备”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。
技术领域
本发明涉及通信领域，尤其涉及一种配额共享方法及信令路由设备。
背景技术
随着通信业务惠及人群的逐渐增加，衍生出了配额共享业务，其中配额可以是流量、通话时长等。所谓配额共享业务是指由主用户承担配额费用，由主用户和多个共享用户共同使用配额的计费方案。
目前，要实现不同用户间的配额共享业务，必须保证各个用户均对应同一计费设备，如：策略与计费规则功能单元(英文全称：Policy and Charging Rules Function，缩写：PCRF)或在线计费系统(英文全称：Online Charging System，缩写：OCS)。
可能存在多个用户对应有多个PCRF(或OCS)，会话管理网关(PDN GateWay，PGW)将各个用户的会话建立请求路由到不同的PCRF上，进而各个用户由不同的PCRF进行计费，便无法实现这些用户间的配额共享业务。
发明内容
本发明实施提供一种配额共享方法及信令路由设备，能够在多个PCRF无法互相通信的场景下，实现多个用户之间的配额共享。
为达到上述目的，本发明的实施例采用如下技术方案：
现有技术中，会话管理网关PGW主要负责会话和承载的管理以及IP地址分配等。PGW接收用户的会话建立请求，并将用户的会话建立请求直接路由至用户对应的PCRF(计费设备)，由用户各自对应的PCRF对用户使用的配额进行计费。本申请在现有组网中引入信令路由设备SPS，意在根据用户之间的共享关系，将用户的会话请求进行重定向，以实现配额共享业务。具体如下：
第一方面，公开了一种配额共享方法，包括：
首先，在用户间的配额共享业务设置后，信令路由设备会接收到管理员配置的相关数据，即所述共享信息数据。这里的共享信息数据指示共享关系信息、主用户的标识与其对应的第一计费设备的对应关系、共享用户的标识与其对应的第二计费设备的对应关系，所述共享关系信息指示主用户与共享用户共享同一配额。举例而言，该共享信息数据可以是 “主用户A：PCRF1；共享用户B：PCRF2；共享关系信息：用户A为主用户，用户B为共享用户，二者共享2G流量”。
其次，当共享用户发起会话请求时，会话管理网关(PGW)接收共享用户的会话建立请求，并将该共享用户的会话建立请求转发至所述信令路由设备。在此，会话建立请求会携带该共享用户的标识。当然，会话管理网关接收其他用户(如：主用户或其他共享用户)的会话建立请求，也会将该用户的会话建立请求转发至所述信令路由设备。
接着，所述信令路由设备会查询预存储的共享信息数据，确定所述用户为共享用户，需要与主用户共享同一配额，因此需要采用主用户的PCRF，即所述第一计费设备作为所述共享用户的计费设备。具体地，可以根据所述用户的标识查询所述共享信息数据，确定所述用户为共享用户。示例的，承上所述的共享信息数据，信令路由设备首先查询所述共享信息数据，确定用户B设置有配额共享业务且主用户为A，进而确定用户B对应的计费设备为主用户A的计费设备。
最后，所述信令路由设备将所述会话建立请求路由至所述第一计费设备，以便所述第一计费设备建立与所述信令路由设备间的第一会话，使得所述主用户与所述共享用户共用共享配额。
现有技术中，存在多个用户对应有多个不同的计费设备，PGW会将各个用户的会话建立请求路由到不同的PCRF上，进而各个用户由不同的PCRF进行计费。这就无法实现由同一计费设备为不同的用户使用配额进行计费，进而也就无法实现主用户和多个共享用户共同使用配额的计费方案，即配额共享。
本发明在现有组网中引入SPS，预先将记录共享业务的相关数据存储在SPS，当SPS接收到PGW转发的某个用户的会话建立请求时，可以查询预先记录的数据确定该用户是否为设置有配额共享业务的用户，若用户设置有配额共享业务，则进一步确定该用户当前会话的计费设备为主用户对应的计费设备，随即将该用户的会话建立请求路由至主用户对应的计费设备，以便主用户对应的计费设备对该用户使用的配额进行计费，实现该用户与主用户共享同一配额的计费方案。
结合第一方面，在第一方面的第一种可能的实现方式中，
若共享业务取消，即所述信令路由设备确定所述主用户与所述共享用户间的配额共享业务满足撤销条件，则采用所述第二计费设备作为所述共享用户的计费设备。
也就是说，当共享业务撤销，共享用户则不能继续使用由主用户付费的配额，需要由自己本身的计费设备对其使用的配额进行计费，因此需要将共享用户的当前会话对应的计费设备为所述共享用户对应的计费设备。
结合第一方面的第一种可能的实现方式，在第一方面的第二种可能的实现方式中，所述方法还包括：
所述信令路由设备向所述第一计费设备发送会话删除消息，使得所述第一计费删除与共享用户之间的当前会话，即所述第一会话。
另外，还会向所述第二计费设备发送会话建立请求，使得所述第二计费设备建立与所述信令路由设备间的第二会话，所述第二会话的会话标识与所述第一会话的会话标识相同。
这样，对于会话管理网关PGW来说，根据会话标识判断该共享用户当前会话还是原来的会话，不会产生业务中断的现象。
结合第一方面的第一种可能的实现方式，在第一方面的第二种可能的实现方式中，所述信令路由设备向所述会话管理网关发送会话变更信息并向所述第二计费器发送会话建立请求，所述会话管理网关接收后向所述第一计费设备发送会话删除消息，第一计费设备器删除所述第一会话。之后，第二计费设备接收会话管理网关发送的会话建立请求，建立所述第二计费设备建立与所述信令路由设备间的第二会话；所述第二会话的会话标识与所述第一会话的会话标识相同。
同样，相对于会话管理网关PGW来说，根据会话标识判断还是原来的会话，不会产生业务中断的现象。
结合第一方面的第一种可能的实现方式，在第一方面的第四种可能的实现方式中，所述方法还包括：
所述信令路由设备接收所述会话管理网关转发的来自所述共享用户的会话建立请求，将所述会话建立请求路由至所述第二计费设备。也就是说，共享业务撤销以后，所述信令路由设备会将共享用户的会话请求转发给该用户本身对应的计费设备。
结合第一方面的第一至第四种可能的实现方式中的任一项，在第一方面的第五种可能的实现方式中，所述撤销条件为：所述主用户与所述共享用户的共享关系解除，或，所述共享配额的剩余量为零，即共享配额已被用完。
第二方面，公开了一种信令路由设备，包括：
接收单元，用于接收共享信息数据；所述共享信息数据指示共享关系信息、主用户的标识与其对应的第一计费设备的对应关系、共享用户的标识与其对应的第二计费设备的对应关系，所述共享关系信息指示主用户与共享用户共享同一配额；
所述接收单元还用于，接收会话管理网关转发的来自所述共享用户的会话建立请求，所述会话建立请求携带所述共享用户的标识；
查询单元，用于查询所述共享信息数据，根据所述共享用户的标识确定所述共享用户对应的计费设备为所述第一计费设备；
发送单元，用于将所述会话建立请求路由至所述第一计费设备，以便所述第一计费设备建立与所述信令路由设备间的第一会话，使得所述主用户与所述共享用户共用共享配额。
现有技术中，存在多个用户对应有多个不同的计费设备，PGW会将各个用户的会话建立请求路由到不同的PCRF上，进而各个用户由不同的PCRF进行计费。这就无法实现由同一计费设备为不同的用户使用配额进行计费，进而也就无法实现主用户和多个共享用户共同使用配额的计费方案，即配额共享。
本发明在现有组网中引入SPS，预先将记录共享业务的相关数据存储在SPS，当SPS接收到PGW转发的某个用户的会话建立请求时，可以查询预先记录的数据确定该用户是否为设置有配额共享业务的用户，若用户设置有配额共享业务，则进一步确定该用户当前会话的计费设备为主用户对应的计费设备，随即将该用户的会话建立请求路由至主用户对应的计费设备，以便主用户对应的计费设备对该用户使用的配额进行计费，实现该用户与主用户共享同一配额的计费方案。
结合第二方面，在第二方面的第一种可能的实现方式中，还包括确定单元，
所述确定单元用于，若确定所述主用户与所述共享用户间的配额共享业务满足撤销条件，则采用所述第二计费设备作为所述共享用户的计费设备。
结合二方面的第一种可能的实现方式，在第二方面的第二种可能的实现方式中，
所述发送单元还用于，向所述第一计费设备发送会话删除消息，使得所述第一计费设备删除所述第一会话；
向所述第二计费设备发送会话建立请求，使得所述第二计费设备建立与所述信令路由设备间的第二会话；所述第二会话的会话标识和所述第一会话的会话标识相同。
结合二方面的第一种可能的实现方式，在第二方面的第三种可能的实现方式中，
所述发送单元还用于，向所述会话管理网关发送会话变更信息并向所述第二计费器发送会话建立请求，以便所述第一计费设备删除所述第一会话，所述第二计费设备建立与所述信令路由设备间的第二会话；所述第二会话的会话标识和所述第一会话的会话标识相同。
结合二方面的第一种可能的实现方式，在第二方面的第四种可能的实现方式中，
所述接收单元还用于，接收所述会话管理网关转发的来自所述共享用户的会话建立请求；
所述发送单元还用于，将所述会话建立请求路由至所述第二计费设备。
结合二方面的第一至第四种可能的实现方式中的任一种，在第二方面的第五种可能的实现方式中，
所述撤销条件为：所述主用户与所述共享用户的共享关系解除，或，共享配额的剩余量为零。

具体实施方式
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，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性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。
现有技术当出现不同用户对应不同的PCRF(或OCS)时，组网中的PGW会将不同用户的会话请求路由至不同的PCRF，因此无法实现配额共享业务。具体地，现有的会话路由流程如图1所示，用户A本身对应的是PCRF1，用户B本身对应的是PCRF2，PGW会将用户A的会话请求路由至PCRF1，将用户B的会话请求路由至PCRF2，由于PCRF1、PCRF2之间无法进行通信(如：PCRF1、PCRF2是异厂家)，用户A、B就不能通过一个PCRF进行计费，也就无法实现共享同一配额的业务。
本发明提供一种通信组网，如图2所示，包括：会话管理网关、信令路由设备、至少两个不同的计费设备。其中，会话管理网关可以是PGW(PDN GateWay，PDN会话管理网关)，用于将用户的请求转发至信令路由设备。信令路由设备可以是SPS(信令业务处理系统(Signaling service Processing System))设备，预先记录有共享业务的相关数据，即本发明所述的共享信息数据。计费设备可以是PCRF。不同于现有技术，本发明提供的通信组网中引入信令路由设备SPS，意在根据用户之间的共享关系，将用户的会话请求进行重定向，以实现配额共享业务。在图2所示的通信组网中，信令路由设备可以将用户的会话建立请求重定向至不是该用户本身对应的计费设备上。示例的，用户A本身对应的是PCRF1，信令路由设备接收会话管理网关转发的用户A的会话建立请求路由至PCRF2。
基于此，本发明实施例提供一种信令路由设备，旨在对用户的会话建立请求进行重定向，以在多个PCRF无法互相通信的场景下，实现多个用户之间的配额共享。
如图3所示，本发明实施例提供的信令路由设备包括：接收器101、发射器102、处理器103以及存储器104。进一步地，参考图3，本发明实施例提供的配额共享方法包括以下步骤：
首先，在用户间的配额共享业务设置后，接收器101会接收到管理员配置的相关数据，即所述共享信息数据。并将所述共享信息数据存储在存储器104中。
这里的共享信息数据指示共享关系信息、主用户的标识与其对应的第一计费设备的对应关系、共享用户的标识与其对应的第二计费设备的对应关系，所述共享关系信息指示主用户与共享用户共享同一配额。举例而言，该共享信息数据可以是“主用户A：PCRF1；共享用户B：PCRF2；共享关系信息：用户A为主用户，用户B为共享用户，二者共享2G流量”。
S1.接收器101接收由会话管理网关(PGW)转发的共享用户的会话建立请求。
具体实现中，会话管理网关(PGW)接收共享用户的会话建立请求，并将该共享用户的会话建立请求转发至所述信令路由设备。在此，会话建立请求会携带该共享用户的标识。当然，会话管理网关接收其他用户(如：主用户或其他共享用户)的会话建立请求，也会将该用户的会话建立请求转发至所述信令路由设备。
S2.处理器103会查询存储器104存储的所述共享信息数据，确定采用所述第一计费设备作为所述共享用户的计费设备。
需要说明的是，根据用户(共享用户)的标识查询共享信息数据，可以确定该用户为共享用户，需要与主用户共享同一配额，因此需要确定所述共享用户对应的计费设备为主用户的PCRF，即所述第一计费设备。具体地，可以根据所述用户的标识查询所述共享信息数据，确定所述用户为共享用户。示例的，承上所述的共享信息数据，信令路由设备首先查询所述共享信息数据，确定用户B设置有配额共享业务且主用户为A，进而确定用户B对应的计费设备为主用户A的计费设备。
S3.发射器102将所述会话建立请求路由至所述第一计费设备，以便所述第一计费设备建立与所述信令路由设备间的第一会话，使得所述主用户与所述共享用户共用共享配额。
在本实施例中，处理器103可以为中央处理器(英文全称：central processing unit，缩写：CPU)。
发射器102可以由光发射器，电发射器，无线发射器或其任意组合实现。例如，光发射器可以是小封装可插拔(英文全称：small form-factor pluggable transceiver，缩写：SFP)发射器(英文全称：transceiver),增强小封装可插拔(英文全称：enhanced small form-factor pluggable，缩写：SFP+)发射器或10吉比特小封装可插拔(英文全称：10Gigabit small form-factor pluggable，缩写：XFP)发射器。电发射器可以是以太网(英文全称：Ethernet)网络接口控制器(英文全称：network interface controller，缩写：NIC)。无线发射器可以是无线网络接口控制器(英文全称：wireless network interface controller，缩写：WNIC)。
接收器101可以由光接收器，电接收器，无线接收器或其任意组合实现。例如，光接收器可以是小封装可插拔接收器,增强小封装可插拔接收器或10吉比特小封装可插拔接收器。电接收器可以是以太网网络接口控制器。无线接收器可以是无线网络接口控制器。
存储器104，用于存储程序代码，并将该程序代码传输给该处理器101，处理器101根据程序代码执行下述指令。存储器104可以包括易失性存储器(英文全称：volatile memory)，例如随机存取存储器(英文全称：random-access memory，缩写：RAM)；存储器104也可 以包括非易失性存储器(英文全称：non-volatile memory)，例如只读存储器(英文全称：read-only memory，缩写：ROM)，快闪存储器(英文全称：flash memory)，硬盘(英文全称：hard disk drive，缩写：HDD)或固态硬盘(英文全称：solid-state drive，缩写：SSD)。存储器104还可以包括上述种类的存储器的组合。
本发明提供的配额共享方法，预先将记录共享业务的相关数据存储在SPS，当SPS接收到PGW转发的某个用户的会话建立请求时，可以查询预先记录的数据确定该用户是否为设置有配额共享业务的用户，若用户设置有配额共享业务，则进一步确定该用户当前会话的计费设备为主用户对应的计费设备，随即将该用户的会话建立请求路由至主用户对应的计费设备，以便主用户对应的计费设备对该用户使用的配额进行计费，实现该用户与主用户共享同一配额的计费方案。
在本发明的优选实施例中，若共享业务取消，即所述信令路由设备确定所述主用户与所述共享用户间的配额共享业务满足撤销条件，则确定所述共享用户对应的计费设备为所述第一计费设备。这里的撤销条件为：所述主用户与所述共享用户的共享关系解除，或，所述共享配额的剩余量为零，即共享配额已被用完。
也就是说，当共享业务撤销，共享用户则不能继续使用由主用户付费的配额，需要由自己本身的计费设备对其使用的配额进行计费，因此采用该所述共享用户本身对应的计费设备作为共享用户的当前会话的计费设备。需要说明的是，当共享业务撤销，对于SPS来说，会接收到管理员配置的更新共享信息数据，该更新共享信息数据指示共享用户不再与主用户共享同一配额。或者是，SPS监测到共享配额被用完，SPS则自发确定共享用户不再与主用户共享同一配额。
在本发明的另一优选实施例中，为了保证共享业务撤销(切换)时会话不中断，所述信令路由设备向所述第一计费设备发送会话删除消息，使得所述第一计费删除与共享用户之间的当前会话，即所述第一会话。
另外，还会向所述第二计费设备发送会话建立请求，使得所述第二计费设备建立与所述信令路由设备间的第二会话，所述第二会话的会话标识和所述第一会话的会话标识相同。
这样，对于会话管理网关PGW来说，根据会话标识判断还是原来的会话，不会产生业务中断的现象。
或者，为保证共享业务撤销(切换)时会话不中断，所述信令路由设备向所述会话管理网关发送会话变更信息并向所述第二计费器发送会话建立请求，所述会话管理网关接收后向所述第一计费设备发送会话删除消息，第一计费设备器删除所述第一会话。之后，第二计费设备接收会话管理网关发送的会话建立请求，建立所述第二计费设备建立与所述信令路由设备间的第二会话；所述第二会话的会话标识和所述第一会话的会话标识相同。
同样，相对于会话管理网关PGW来说，根据会话标识判断还是原来的会话，不会产生业务中断的现象。
另外需要说明的是，所述信令路由设备接收所述会话管理网关转发的来自所述共享用户的会话建立请求，将所述会话建立请求路由至所述第二计费设备。也就是说，共享业务 撤销以后，所述信令路由设备会将共享用户的会话请求转发给该用户本身对应的计费设备。
实施例1：
本发明实施例提供一种配额共享方法，以会话管理网关可为PGW、信令路由设备可以为SPS、用户A对应的是PCRF1、用户B对应的是PCRF2，用户A为主用户为例，参考图4，所述方法包括以下步骤：
101、PGW接收用户B的会话建立请求，并将用户B的会话建立请求转发至所述SPS。
其中，所述会话建立请求可以是Gx-CCRi消息。该会话建立请求携带该用户B的标识，如：B。
当然，PGW接收到任何用户的会话建立请求，都是会将其会话建立请求转发至SPS的。
在此之前，在用户间的配额共享业务设置后，SPS会接收相关数据，即共享信息数据。这里的共享信息数据指示共享关系信息、主用户的标识与其对应的计费设备的对应关系、共享用户的标识与其对应的计费设备的对应关系，所述共享关系信息指示主用户与共享用户共享同一配额。
举例而言，该共享信息数据可以是“主用户A：PCRF1；共享用户B：PCRF2；用户A为主用户，用户B为共享用户，二者共享2G流量”。
102、所述SPS接收用户B的会话建立请求，根据用户B的标识确定采用PCRF1作为用户B的计费设备。
其中，用户A为主用户，那么PCRF1即本发明所述的第一计费设备。用户B本身对应的计费设备PCRF2，即为本发明所述的第二计费设备。
具体实现中，所述SPS会根据用户B的标识查询所述共享信息数据，确定所述共享用户配置有配额共享业务，需要与主用户共享同一配额，因此需要确定为该共享用户计费的计费设备，即对应的主用户的PCRF。具体地，可以所述主计费设备为所述主用户对应的计费设备。
示例的，承上所述的共享信息数据，SPS首先查询所述共享信息数据，确定用户B设置有配额共享业务，进而确定主用户A的计费设备PCRF1为所述共享用户B的当前会话对应的计费设备。
103、所述SPS将所述会话建立请求路由至PCRF1。
104、PCRF1建立与所述SPS间的第一会话，使得所述用户B与用户A共用共享配额。
这样，响应用户B的会话请求建立的PCRF1建立与所述SPS间的第一会话，能够使得PCRF1为用户B的会话进行计费管理，实现用户B与主用户间的配额共享。
现有技术中，存在多个用户对应有多个不同的计费设备，PGW会将各个用户的会话建立请求路由到不同的PCRF上，进而各个用户由不同的PCRF进行计费。这就无法实现由同一计费设备为不同的用户使用配额进行计费，进而也就无法实现主用户和多个共享用户共同使用配额的计费方案，即配额共享。
本发明在现有组网中引入SPS，预先将记录共享业务的相关数据存储在SPS，当SPS接收到PGW转发的某个用户的会话建立请求时，可以查询预先记录的数据确定该用户是否为设置有配额共享业务的用户，若用户设置有配额共享业务，则进一步确定该用户当前会话的计费设备为主用户对应的计费设备，随即将该用户的会话建立请求路由至主用户对应的计费设备，以便主用户对应的计费设备对该用户使用的配额进行计费，实现该用户与主用户共享同一配额的计费方案。
在本发明的优选实施例中，若共享业务取消，即所述信令路由设备确定所述主用户与所述共享用户间的配额共享业务满足撤销条件，则确定所述共享对应的计费设备为第二计费设备，即所述共享用户本身对应的计费设备。
其中，所述撤销条件为：所述主用户与所述共享用户的共享关系解除，或，所述共享配额的剩余量为零，即共享配额已被用完。
示例的，当主用户A、共享用户B的共享关系解除，或共享配额被用完，SPS则确定用户B对应的计费设备为其本身的计费设备PCRF2。
也就是说，当共享业务撤销，共享用户则不能继续使用由主用户付费的配额，需要由自己本身的计费设备对其使用的配额进行计费，因此需要采用所述共享用户本身对应的计费设备作为该共享用户的当前会话的计费设备。
进一步地，所述信令路由设备接收所述会话管理网关转发的来自所述共享用户的会话建立请求，将所述会话建立请求路由至所述共享用户对应的计费设备。也就是说，共享业务撤销以后，所述信令路由设备会将该用户的会话请求转发给其本身的计费设备。
另外，当共享业务撤销时，为保证业务不中断，参考图5，所述方法还包括：
201、所述SPS向所述PCRF1发送会话删除消息。
其中，所述会话删除消息可以是Gx-CCRt消息。当然，该会话删除消息携带第一会话的会话标识，使得PCRF1可以将该会话标识对应的会话删除。
也就是说，若共享用户与主用户的计费设备(PCRF1)建立会话连接，与主用户共享同一配额，当共享用户与主用户间的共享业务撤销时，共享用户不能继续与主用户共享同一配额，因此，首先需要向主用户的计费设备发送会话删除消息，指示主用户的计费设备删除与共享用户之间的会话。
202、所述PCRF1删除所述第一会话。
其中，所述第一会话即所述PCRF1与共享用户(用户B)之间的当前会话。
203、SPS向所述用户B对应的PCRF2发送会话建立请求。
其中，会话建立请求可以是Gx-CCRi消息。需要说明的是，该会话建立请求需要携带第一会话的会话标识，以便在共享业务撤消后，共享用户本身的计费设备(PCRF2)能够建立与第一会话相同的会话，使得共享用户的业务不会中断。
当共享业务撤销，共享用户则不能继续使用由主用户付费的配额，需要由自己本身的 计费设备对其使用的配额进行计费，因此需要将共享用户的当前会话对应的计费设备为所述共享用户对应的计费设备。
204、所述用户B对应的PCRF2建立与所述SPS间的第二会话，所述第二会话的会话标识和所述第一会话的会话标识相同。
这样，相对于PGW来说，根据会话标识判断还是原来的会话，不会产生业务中断的现象。
或者，当共享业务撤销时，为保证业务不中断，参考图6，所述方法还包括：
301、SPS向PGW发送会话变更信息。
这里的会话变更消息可以是特殊的通知消息，如：RAR。
302、PGW接收后向PCRF1发送会话删除消息。
同样，当然，该会话删除消息携带第一会话的会话标识，使得PCRF1可以将该会话标识对应的会话删除。
303、PCRF1删除所述第一会话。
304、PGW向所述用户B对应的计费器PCRF2发送会话建立请求。
需要说明的是，该会话建立请求需要携带第一会话的会话标识，以便在共享业务撤消后，共享用户本身的计费设备(PCRF2)能够建立与第一会话相同的会话，使得共享用户的业务不会中断。
305、PCRF2建立所述共享用户对应的计费设备建立与所述信令路由设备间的第二会话；所述第二会话的会话标识和所述第一会话的会话标识相同。
同样，相对于PGW来说，根据会话标识判断还是原来的会话，不会产生业务中断的现象。
本发明提供的配额共享方法，预先将记录共享业务的相关数据存储在SPS，当SPS接收到PGW转发的某个用户的会话建立请求时，可以查询预先记录的数据确定该用户是否为设置有配额共享业务的用户，若用户设置有配额共享业务，则进一步确定该用户当前会话的计费设备为主用户对应的计费设备，随即将该用户的会话建立请求路由至主用户对应的计费设备，以便主用户对应的计费设备对该用户使用的配额进行计费，实现该用户与主用户共享同一配额的计费方案。
另外，在共享关系撤销时，还可以进行信令交互，删除共享用户与主用户的计费设备间的会话，建立共享用户与其本身的计费设备间的会话，且使用相同的会话标识，使得会话不中断。
