具体实施方式
应当理解，此处所描述的实施例仅仅用以解释本公开，并不用于限定本公开。在不冲突的情况下，以下实施例和实施例中的特征可以相互组合。
现在将参考附图描述实现本发明可选实施例的移动终端。在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本发明实施例的说明，其本身并没有特定的意义。因此，″模块″与″部件″可以混合地使用。
实施例一
如图1所示，本发明的一个实施例提出一种计费方法，包括步骤S110和S120。
在S110中，SGSN接收移动终端发出的路由区更新请求消息，路由区更新请求消息中包含移动终端的小区信息。
在S120中，SGSN向GGSN发出携带小区信息的更新PDP上下文请求消息，以用于供GGSN按小区信息输出用于计费的话单。
其中，GGSN表示网关GPRS支持节点，GPRS表示通用分组无线服务技术，PDP表示分组数据协议。
本实施例的技术方案基于服务通用分组无线服务技术的支持节点SGSN实现。运营商为了提高计费精度，希望按照全球小区对用户进行计费，根据本实施例的技术方案，SGSN内RAU时把用户当时的小区信息带给GGSN以进行话单计费；相比于相关技术中RAI粒度太大，导致计费精度不够高的问题，本实施例 的技术方案可以减小小区信息粒度，从而可以更精确地对小区进行计费。
实施例二如图2所示，本发明的一个实施例提出一种计费方法，包括S210-S230。
在S210中，SGSN接收移动终端发出的路由区更新请求消息，路由区更新请求消息中可以包含移动终端的小区信息。
在本实施例中，在移动终端在2G(2nd Generation Mobile Communication System第二代移动通信系统)网络中发生路由区更新时，小区信息可以为全球小区识别码(Cell Global Identifier，CGI)；在移动终端在3G(3rd Generation Mobile Communication System第三代移动通信系统)网络中发生路由区更新时，小区信息可以为服务区码(Service Area Code，SAC)。
在S220中，SGSN判断接收的小区信息相比于已记录的小区信息是否变化。
在S230中，当判定接收的小区信息相比于已记录的小区信息发生变化时，SGSN向GGSN发出携带小区信息的更新PDP上下文请求消息，以用于供GGSN按小区信息输出用于计费的话单。
在本实施例中，运营商为了提高计费精度，希望按照全球小区对用户进行计费，根据本实施例的技术方案，SGSN内RAU时把用户当时的SAC(Service Area Code服务区码)/CGI(Cell Global Identifier全球小区识别码)信息带给GGSN，GGSN在小区位置信息改变的时候输出话单，并在G-CDR内的ULI信息里填报SAC/CGI位置信息，即话单里带LAC+SAC信息或LAC+CGI信息。相比于RAI粒度太大而导致计费精度不够高的问题，本实施例可以提高位置精度，在话单中记录下发生RAU时候的用户位置信息，例如该位置信息可以包括3G的SAC或者2G的CGI，则用户在话单查询的时候，可以得到用户的SAC或者CGI信息，而不只是路由区标识(RoutingArea Identity，RAI)信息；因为RAI的范围太大，3G的SAC或者2G的CGI与RAI相比，范围要小很多，因而可以实现更精细的计费。本实施例的方法可以应用于2G到2G局内RAU的示例如图3所示，包括S301-S306。
在S301中，移动台(Mobile Station，MS，可用于2G网络的移动终端)发送路由区更新请求消息到SGSN，消息中携带了位置信息，如果位置信息中只有小区(CGI)信息改变，则SGSN可以发送更新PDP上下文请求消息到GGSN，通知GGSN移动台的新小区信息。
在S302中，实现安全功能。
在S303中，SGSN向移动台发送路由区更新接收消息。
在S304中，SGSN向GGSN发送更新PDP上下文请求消息，通知GGSN移动台的新小区信息，GGSN发现用户的位置信息发生变化则触发话单上报。
在S305中，GGSN向SGSN发送更新PDP上下文响应消息。
在S306中，移动台向SGSN发送路由区更新完成消息。
以上示例中步骤S301以及步骤S304到S305中，SGSN收到路由区更新请求消息，消息中携带了位置信息，如果位置信息中只有小区(CGI)信息改变，则SGSN会发送更新PDP上下文请求消息到GGSN，把移动台的新小区信息通知GGSN。而在相关技术中，当只有小区信息改变，则SGSN不会发送更新PDP上下文请求消息，所以GGSN无法知道移动台的小区信息发生了变化，无法上报基于新小区的话单，因此无法实现运营商基于小区的精细计费。
相应地，本实施例的方法可应用于3G到3G局内RAU的示例，如图4所示，包括S401-S406。
在S401中，用户设备(UE，3G网络内的移动终端)发送路由区更新请求消息到SGSN，消息中可以携带位置信息，如果位置信息中只有小区(SAC)信息改变，则SGSN会发送更新PDP上下文请求消息到GGSN，通知GGSN用户设备的新小区信息。
在S402中，实现安全功能。
在S403中，SGSN向用户设备发送路由区更新接收消息。
在S404中，SGSN向GGSN发送更新PDP上下文请求消息，通知GGSN用户设备的新小区信息，GGSN发现用户的位置信息发生变化则触发话单上报。
在S405中，GGSN向SGSN发送更新PDP上下文响应消息。
在S406中，用户设备向SGSN发送路由区更新完成消息。
以上示例中步骤S401以及步骤S404到S405，SGSN收到路由区更新请求消息，消息中可以携带有位置信息，如果位置信息中只有小区(SAC)信息改变，则SGSN会发送更新PDP上下文请求消息到GGSN，把移动台的新小区信息通知GGSN。
实施例三
如图5所示，本发明的一个实施例提出一种计费方法，包括S510-S550。
在S510中，SGSN与移动终端对应的源无线链路控制器(Source Radio Network Controller RNC，即切换前的无线链路控制器)以及目标RNC(Target RNC，即切换后的无线链路控制器)交互获取相应的切换信息；切换信息表示移动终端从源RNC切换连接至目标RNC并造成移动终端的全球小区识别码信息变化。在本实施例中，在接收移动终端发送路由区更新请求消息前，SGSN即可确定移动终端发生RAU，在移动终端未发送路由区更新请求消息时，SGSN可以主动向移动终端请求路由区更新请求消息。
在S520中，SGSN接收移动终端发出的路由区更新请求消息，路由区更新请求消息中包含移动终端的小区信息。
在S530中，SGSN判断接收的路由区信息相比于已记录的路由区信息是否发生变化。
在S540中，SGSN判断接收的小区信息相比于已记录的小区信息是否变化。
在S550中，在判定接收的路由区信息相较于已记录的路由区信息未发生变化且接收的小区信息相较于已记录的小区信息发生变化时，SGSN向GGSN发出携带小区信息的更新PDP上下文请求消息。
在实施例中，当路由区信息发生变化时，则GGSN可以按照路由区信息进行计费，或者也可以在路由区信息的基础上基于小区信息进行计费。
本实施例的方法可以应用于3G网络中的移动终端发生局内切换后的流程图，参照图6，包括S601-S618。
在S601中，源RNC发送重定位请求到SGSN。
在S602中，SGSN发送重定位请求到目标RNC。
在S603中，实现安全功能。
在S604中，目标RNC发送重定位请求证实消息到SGSN。
在S605中，SGSN发送重定位命令到源RNC。
在S606中，源RNC发送前传数据消息到目标RNC。
在S607中，源RNC发送重定位执行消息到目标RNC。
在S608中，目标RNC发送重定位检测消息到SGSN。
在S609中，目标RNC发送重定位完成消息到SGSN。
在S610中，目标RNC发送RAN移动信息消息到用户设备。
在S611中，用户设备发送无线接入网(Radio Access Network，RAN)移动信息证实消息到目标RNC。
在S612中，SGSN发送接口单元(Interface Unit，IU)释放命令消息到源RNC。
在S613中，源RNC发送IU释放完成消息到SGSN。
在S614中，切换后的用户设备发送路由区更新请求消息到SGSN，消息中可以携带有位置信息，如果位置信息中只有小区(SAC)信息改变，则SGSN可以发送更新PDP上下文请求消息到GGSN，通知GGSN用户设备的新的小区信息。
在S615中，SGSN向用户设备发送路由区更新接收消息。
在S616中，SGSN向GGSN发送更新PDP上下文请求消息，通知GGSN用户设备的新的小区信息，GGSN发现用户的位置信息发生变化则触发话单上报。
在S617中，GGSN向SGSN发送更新PDP上下文响应消息。
在S618中，用户设备向SGSN发送路由区更新完成消息。
以上示例中步骤S614以及步骤S616到S617，SGSN收到路由区更新请求消息，消息中可以携带有位置信息，当位置信息中只有小区(SAC)信息改变，则SGSN可以发送更新PDP上下文请求消息到GGSN，把移动台的新的小区信息通知GGSN。
实施例四
如图7所示，本发明的一个实施例提出一种计费装置，包括：
信息接收模块710，设置为接收移动终端发出的路由区更新请求消息，路由区更新请求消息中包含移动终端的小区信息。
信息发送模块720，设置为向GGSN发出携带小区信息的更新PDP上下文请求消息，以用于供GGSN按小区信息输出用于计费的话单；
其中，GGSN表示网关GPRS支持节点，GPRS表示通用分组无线服务技术，PDP表示分组数据协议。
本实施例的技术方案可以基于SGSN实现。运营商为了提高计费精度，希望按照全球小区对用户进行计费，根据本实施例的技术方案，SGSN内RAU时可以把用户当时的小区信息带给GGSN以进行话单计费；相比于相关技术的方案，由于RAI粒度太大而导致计费精度不够高，而本实施例的技术方案可以降低小区信息粒度，从而可以更精确地进行小区计费。
实施例五
如图8所示，本发明的一个实施例提出一种计费装置，包括：
信息接收模块810，设置为接收移动终端发出的路由区更新请求消息，路由区更新请求消息中包含移动终端的小区信息。
在本实施例中，在移动终端在2G(2nd Generation Mobile Communication System第二代移动通信系统)网络中发生路由区更新时，小区信息为全球小区识别码信息CGI；在移动终端在3G(3rd Generation Mobile Communication System第三代移动通信系统)网络中发生路由区更新时，小区信息为服务区码信息SAC。
第一判断模块820，设置为判断接收的小区信息相比于已记录的小区信息是否变化。
信息发送模块830，设置为当判定接收到的小区信息相较于已记录的小区信息发生变化时，向GGSN发出携带小区信息的更新PDP上下文请求消息，以用于供GGSN按小区信息输出用于计费的话单。
在本实施例中，运营商为了提高计费精度，希望按照全球小区对用户进行计费，根据本实施例的技术方案，SGSN内RAU时把用户当时的SAC(Service Area Code服务区码)/CGI(Cell Global Identifier全球小区识别码)信息带给GGSN，GGSN在小区位置信息改变的时候输出话单，并在G-CDR内的ULI信息里填报SAC/CGI位置信息，即话单里带LAC+SAC或LAC+CGI信息。相比于相关技术的方案，由于RAI粒度太大而导致计费精度不够高，本实施例的技术方案可以提高位置精度，在话单中记录下发生RAU时候的用户位置信息，包括3G的SAC或者2G的CGI，则用户在话单查询的时候，可以得到用户的SAC或者CGI信息，而不只是RAI(Routing Area Identity路由区标识)信息；因为相关技术中的RAI的范围太大，而3G的SAC或者2G的CGI与RAI相比，范围要小很多，因此可以实现更精细的小区计费。
实施例六
如图9所示，本发明的一个实施例提出一种计费装置，包括：
交互模块910，设置为与移动终端对应的源RNC(Source RNC，即切换前的无线链路控制器)以及目标RNC(Target RNC，即切换后的无线链路控制器) 交互获取相应的切换信息；切换信息表示移动终端从源RNC切换连接至目标RNC并造成移动终端的全球小区识别码信息变化。在本实施例中，在接收移动终端发送路由区更新请求消息前，SGSN即可确定移动终端发生RAU，在移动终端未发送路由区更新请求消息时，SGSN可以主动向移动终端请求路由区更新请求消息。
信息接收模块920，设置为接收移动终端发出的路由区更新请求消息，路由区更新请求消息中包含移动终端的小区信息。
第二判断模块930，设置为判断接收的路由区信息相比于已记录的路由区信息是否发生变化。
