具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的各实施方式进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施方式中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施方式的种种变化和修改，也可以实现本申请所要求保护的技术方案。
本申请的一实施例涉及一种国际漫游短消息的计费方法，应用于IP-SM-GW，方法包括获取S-CSCF发送的第三方注册消息，其中，第三方注册消息中携带用户的漫游网络信息，第三方注册消息基于来自P-CSCF发送的用户注册消息生成；从第三方注册消息中解析出漫游网络信息；在收到用户发送的短消息的情况下，向计费系统发送用户的漫游网络信息，供计费系统根据漫游网络信息对用户进行计费。
在本申请实施例中，运营商新建专用于4G或5G用户国际漫游的国际关口局，关口局包含P-GW/UPF(Packet Data Network Gateway，PDN网关/User Plane Function，用户面功能)及P-CSCF等专用网元，负责把国际漫出用户的IMS注册及消息路由至用户归属IMS网络。
本申请实施例的网络架构中包括以下设备：IP-SM-GW、SMSC(Short Message Service Center，短消息中心)、4G核心网关设备S-GW(Serving Gateway，服务网关)/P-GW、5G核心网设备UPF、5G网络PCF(Policy Control Function，策略控制功能、4G网络策略和计费规则功能PCRF(Policy and Charging Rule Function)、HSS(Home Subscriber Server，归属签约用户服务器)以及IMS网络设备P-CSCF、I-CSCF(询问呼叫会话控制功能，Interrogating Call Session Control Function)和S-CSCF等。
其中，IP-SM-GW主要用于记录用户漫游网络的PLMNID(Public Land Mobile Network Identification,公共陆地移动网)和向计费系统提供MCC和MNC信息；SMSC主要用于终端短消息的存储、转发以及重试；4G核心网设备S/P-GW主要用于分组数据的路由转发；PCRF主要用于策略控制决策和基于流计费控制的功能；5G核心网设备UPF主要执行不同的用户面处理；PCF主要提供策略规则供网络实体实施执行；HSS主要负责管理用户的签约数据和移动用户的位置信息；P-CSCF主要用于向I-CSCF转发UE(User Equipment，用户设备)发来的SIP(Session initialization Protocol，会话初始协议)注册请求以及向S-CSCF转发UE发送的SIP消息；I-CSCF主要用于为用户指定某个S-CSCF来执行SIP注册以及将其他网络传送的SIP请求转发到S-CSCF；S-CSCF主要用于处理注册请求，通过HSS使注册请求生效，以及与各种应用服务器交互提供多媒体业务。
4G网络基于S8HR方案的国际漫游短消息系统如图1所示，运营商在支持4G国际漫游时需要在国际关口局建设国际漫游专用P-GW和P-CSCF，4G用户漫游到国外网络后，发送短消 息路径如图中标注序号：
UE->漫游地S-GW->国际关口局P-GW->国际关口局P-CSCF->I-CSCF->S-CSCF->IP-SM-GW->SMSC。
5G网络基于N9HR方案的国际漫游短消息系统如图2所示。运营商在支持5G国际漫游时需要在国际关口局建设国际漫游专用UPF和P-CSCF，5G用户漫游到国外网络后，发送短消息路径如图中标注序号：
UE->漫游地UPF->国际关口局UPF->国际关口局P-CSCF->I-CSCF->S-CSCF->IP-SM-GW->SMSC。
下面对本实施例中的方法的实现细节进行具体的说明，以下内容仅为方便理解本方案的实现细节，并非实施本方案的必须。具体流程如图3所示，可包括如下步骤：
在步骤301中，获取S-CSCF发送的第三方注册消息，其中，第三方注册消息中携带用户的漫游网络信息，第三方注册消息基于来自P-CSCF发送的用户注册消息生成。
在一个例子中，P-CSCF发送的用户注册消息的PVNI头域中有漫游网络信息，即PLMN ID。其中，漫游消息中包含MNC(Mobile Network Code，移动网络号码)和MCC(Mobile Country Code，移动信号国家码)。
在一个例子中，国际关口局P-CSCF将携带PVNI头域的IMS初始注册消息传送到用户归属的S-CSCF，IP-SM-GW从S-CSCF获取携带PVNI头域的第三方IP短消息注册消息。
另外，IP-SM-GW收到第三方注册消息后，向HSS发送PUR(Profile-Update-Request，用户信息更新请求)消息，供HSS完成用户的注册，当IP-SM-GW收到HSS发送的PUA(Profile-Update-Answer，用户信息更新应答)响应时，则说明用户注册成功，此时IP-SM-GW还需向S-CSCF返回注册响应。
在一个例子中，4G或5G用户国际漫游场景下的IMS注册流程参考图4，具体步骤如下：
在步骤401中，4G或5G漫游UE发起到第一方注册消息，经漫游地网络提交到国际关口局漫游专用P-CSCF。
在步骤402中，P-CSCF查询PCF/PCRF获取用户漫游地运营商的PLMNID，将信息填写在第一方注册消息的头域字段PVNI中，经I-CSCF转发至S-CSCF。
在步骤403中，S-CSCF返回200OK响应。
在步骤404中，P-CSCF向UE返回200 OK响应。
在步骤405中，S-CSCF向预设IP-SM-GW发起第三方注册消息，携带PVNI头域信息。
在步骤406中，预设IP-SM-GW收到第三方注册消息，记录MNC及MCC等漫游信息，然后发送PUR消息注册到HSS。
在步骤407中，HSS给IP-SM-GW返回PUA响应。
在步骤408中，IP-SM-GW给S-CSCF返回第三方注册响应。
在步骤302中，从第三方注册消息中解析出漫游网络信息。
在一个例子中，IP-SM-GW从PVNI头域中解析出漫游网络信息中的MNC和MCC信息，并保存到本地的用户注册信息表中。
在步骤303中，在收到用户发送的短消息的情况下，向计费系统发送用户的漫游网络信息，供计费系统根据漫游网络信息对用户进行计费。
具体地说，在用户发送国际漫游短信息时，IP-SM-GW将已保存的用户的漫游网络信息发 送给用户，使得计费系统能针对国际漫游短信进行收费。
进一步地，在采用离线计费的情况下，向计费系统发送携带用户的漫游网络信息的短消息话单文件，供计费系统根据用户的漫游网络信息对用户进行计费，即在运营商采用离线计费方式时，IP-SM-GW查询本地保存的主叫用户的注册信息，获取用户当前漫游网络信息中的包含MNC和MCC等信息的PLMN ID，生成短消息话单文件；IP-SM-GW向计费系统传送带有MNC和MCC信息的短消息话单文件，供计费系统对漫游用户进行计费。
在一个例子中，在运营商采用离线计费的方式下，4G或5G用户国际漫游场景下短消息发送计费流程参考图5所示，具体步骤如下：
在步骤501中，4G或5G漫游UE发起MO(Mobile Originate上行短消息)短消息，经漫游地网络提交到国际关口局，然后转发到用户归属IP-SM-GW。
在步骤502中，IP-SM-GW将短消息转发到短消息中心。
在步骤503中，短消息中心返回起呼成功响应。
在步骤504中，IP-SM-GW查询本地保存的主叫用户的注册信息，获取用户当前漫游网络的PLMNID，包含MNC及MCC等信息，生成短消息话单文件。
在步骤505中，IP-SM-GW将短消息话单文件传送到计费系统。
在步骤506中，IP-SM-GW给UE返回短消息起呼响应。
在步骤507中，UE返回200 OK响应。
更进一步地，在采用在线计费的情况下，向在线计费系统发送携带用户的漫游网络信息的计费认证消息，供在线计费系统根据用户的漫游网络信息对用户进行实时计费。即在运营商采用在线计费方式时，IP-SM-GW查询本地保存的主叫用户的注册信息，获取用户当前漫游网络包含MNC和MCC等信息的PLMN ID；IP-SM-GW将用户拜访地的MCC和MNC信息添加到OCS系统的计费认证消息中，向OCS系统发送携带MNC和MCC信息的计费认证消息，供OCS系统进行漫游用户的实时计费。
在一个例子中，在运营商采用在线计费的方式下，4G或5G用户国际漫游场景下短消息发送计费流程参考图6所示，具体步骤如下：
在步骤601中，4G或5G漫游UE发起SIP短消息，经漫游地网络提交到国际关口局，然后转发到用户归属IP-SM-GW。
在步骤602中，IP-SM-GW向OCS系统发起CCR(Credit Control Request，在线计费认证)，携带用户漫游地PLMN ID信息。
在步骤603中，OCS系统向IP-SM-GW返回CCA(Credit Control Answer，在线计费认证应答)响应。
在步骤604中，如果在线计费成功，IP-SM-GW给漫游UE返回202成功响应。
在步骤605中，IP-SM-GW将短消息转发到短消息中心。
在步骤606中，短消息中心返回起呼成功响应。
在步骤607中，IP-SM-GW给UE返回短消息起呼响应。
在步骤608中，UE返回200 OK响应。
本申请实施例提供的国际漫游短消息的计费方法，通过获取携带用户漫游网络信息的注册消息并将注册消息存储在本地的信息列表中，使得当用户在发送国际漫游短消息时，能将用户的漫游地信息发送至短消息中心，从而短消息中心能够根据用户的漫游地信息对用户的 国际漫游短消息进行计费，避免了用户在国际漫游情况下发送的短消息和未国际漫游情况下发送的短消息在短消息中心生成的短消息计费话单完全相同的问题，实现了短消息中心对漫游短消息的计费。
本申请实施例还涉及一种国际漫游短消息的计费方法，其中，应用于P-CSCF，方法包括：
下面对本实施例中的国际漫游短消息的计费方法的实现细节进行具体的说明，以下内容仅为方便理解本方案的实现细节，并非实施本方案的必须。具体流程如图7所示，可包括如下步骤：
在步骤701中，在接收到用户发起的用户注册消息后，获取用户的漫游网络信息。
具体地说，在运营商采用HR方式的国际漫游方案的情况下，通过向用户归属网络的策略控制功能PCF或者策略和计费规则功能PCRF订阅漫游地运营商的漫游网络变更信息，获取用户的漫游网络信息。
在一个例子中，P-CSCF通过向用户归属网络的PCF/PCRF订阅漫游地运营商的PLMN ID变更信息，来获取用户的漫游网络信息，4G或5G用户在国际漫游场景下，P-CSCF获取漫游PLMN ID的流程如下所示，具体流程如下：
首先，国际关口局P-CSCF获取4G或5G漫游UE发起到第一方注册消息，其中，所述注册消息，经漫游地网络提交到国际关口局漫游专用P-CSCF。
然后，P-CSCF向用户归属网络PCF/PCRF订阅用户漫游地运营商的PLMN ID变更信息。
最后，当用户漫游网络PLMN ID发生变化时，用户归属地PCF/PCRF将变更后的PLMN ID信息发送到P-CSCF。
更进一步地，如果运营商采用LB(Local Breakout，本地疏通，与HR归属地路由相对，LB为在当地漫游网的络疏通业务，HR为归属地疏通业务)方式的国际漫游方案，由于P-CSCF位于漫游地，P-CSCF可以直接获取用户漫游地运营商的PLMN ID信息，并直接携带PLMN ID发送到用户归属网络，不需要执行上述向用户归属网络PCF/PCRF订阅用户漫游地运营商的PLMN ID变更信息的操作。
在步骤702中，在用户注册消息中添加用户的漫游网络信息；
在一个例子中，在国际关口局P-CSCF收到国际漫游用户终端发送的IMS初始注册消息后，将获取到的用户漫游网络信息即PLMN ID信息，填写到注册消息的PVNI头域，其中，PLMN ID信息包括MCC和MNC信息。
在步骤703中，向S-CSCF发送漫游信息添加后的用户注册消息，供S-CSC向IP短消息网关IP-SM-GW发送第三方注册消息，其中，第三方注册消息中携带用户的漫游信息；所述第三方注册消息用于IP-SM-GW在收到用户发送的短消息的情况下，向计费系统发送用于对用户进行计费的漫游网络信息。
在一个例子中，国际关口局P-CSCF将携带用户漫游网络信息的IMS初始注册消息传送到用户归属的S-CSCF，S-CSCF将携带用户漫游网络信息的第三方IP短消息注册消息传送给IP-SM-GW。在漫游用户发送短消息时，IP-SM-GW将保存的MCC和MNC信息提供给计费系统，计费系统根据MCC和MNC信息进行离线或在线计费。
本申请实施例提供的国际漫游短消息的计费方法，通过在收到用户的短消息注册消息时，获取用户漫游网络信息，并将用户漫游网络信息添加到短消息注册消息中，并将携带用户漫游网络消息的注册消息发送至S-CSCF，供S-CSCF生成携带用户漫游网络信息的第三方注册 消息并发送至IP-SM-GW，使得当用户在发送国际漫游短消息时，IP-SM-GW能将获取的用户漫游网络信息发送至短消息中心，从而短消息中心能够根据用户的漫游地信息对用户的国际漫游短消息进行计费，避免了用户在国际漫游情况下发送的短消息和未国际漫游情况下发送的短消息在短消息中心生成的短消息计费话单完全相同的问题，实现了短消息中心对漫游短消息的计费。
本申请实施例还提供了一种国际漫游短消息的计费方法的交互图，参考图8所示，具体步骤如下：
在步骤801中，国际关口局P-CSCF在接收到国际漫游用户终端经漫游地网络提交发送的IMS初始注册消息后，获取用户漫游网络信息，并在注册消息的PVNI头域填写包含MCC和MNC信息的用户漫游网络信息。
在步骤802中，国际关口局P-CSCF将IMS初始注册消息传送到用户归属的S-CSCF。
在步骤803中，S-CSCF将携带PVNI头域的第三方IP短消息注册消息传送给IP-SM-GW。
在步骤804中，IP-SM-GW从PVNI中取出MNC和MCC信息保存在本地的用户注册信息表中。
在步骤805中，运营商国际关口局P-CSCF接收国际漫游用户提交MO短消息。
在步骤806中，国际关口局P-CSCF将消息转发到用户归属的S-CSCF，用户归属的S-CSCF转发到归属IP-SM-GW。
在步骤807中，IP-SM-GW收到用户提交的MO短消息后，查询保存在本地的注册信息表中的MNC和MCC信息，将拜访地的MCC和MNC记录到短消息话单文件中。
在步骤808中，IP-SM-GW将短消息话单文件传送给计费系统。
在步骤809中，计费系统根据用户拜访地的MCC和MNC信息对漫游短消息进行计费。
上述例子是运营商采用离线计费的方式对用户的国际漫游短消息进行计费，当运营商采用在线计费的方式时，参考图9所示，具体步骤如下：
在步骤901中，国际关口局P-CSCF在接收到国际漫游用户终端经漫游地网络提交发送的IMS初始注册消息后，在注册消息的PVNI头域填写包含MCC和MNC信息的用户漫游网络信息。
在步骤902中，国际关口局P-CSCF将IMS初始注册消息传送到用户归属的S-CSCF。
在步骤903中，S-CSCF在第三方IP短消息注册消息中携带PVNI头域传送给IP-SM-GW。
在步骤904中，IP-SM-GW从PVNI中取出MNC和MCC信息保存在本地的用户注册信息表中。
在步骤905中，国际漫游用户提交MO(Message Originated)短消息，经漫游地网络发送到归属运营商国际关口局P-CSCF。
在步骤906中，国际关口局P-CSCF将消息转发到用户归属的S-CSCF，用户归属的S-CSCF转发到归属IP-SM-GW。
在步骤907中，IP-SM-GW收到用户提交的MO短消息后，查询保存在本地的注册信息表中的MNC和MCC信息，IP-SM-GW将用户拜访地的MCC和MNC信息添加到发送至OCS系统的计费认证消息中。
在步骤908中，IP-SM-GW将计费认证消息传送给OCS系统。
在步骤909中，OCS系统根据拜访地的MCC和MNC信息对漫游短消息进行实时计费。
本申请实施例提供的国际漫游短消息的计费方法，在4G或5G国际漫游用户的IMS注册流程，预设IP-SM-GW记录用户漫游网络的PLMN ID；在漫游用户发送短消息时，预设IP-SM-GW将MCC和MNC信息提供给计费系统，计费系统根据漫游标识进行离线或在线计费，使得当用户在发送国际漫游短消息时，IP-SM-GW能将获取的用户漫游网络信息发送至短消息中心，从而短消息中心能够根据用户的漫游地信息对用户的国际漫游短消息进行计费，避免了用户在国际漫游情况下发送的短消息和未国际漫游情况下发送的短消息在短消息中心生成的短消息计费话单完全相同的问题，实现了短消息中心对漫游短消息的计费。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
本申请实施例还涉及一种国际漫游短消息的计费装置，应用于IP-SM-GW，如图10所示，包括：注册消息获取模块1001、漫游网络信息解析模块1002以及发送模块1003。
具体地说，注册消息获取模块1001：获取S-CSCF发送的第三方注册消息，其中，第三方注册消息中携带用户的漫游网络信息，第三方注册消息基于来自P-CSCF发送的用户注册消息生成；漫游网络信息解析模块1002：用于从第三方注册消息中解析出漫游网络信息；发送模块1003：用于在收到用户发送的短消息的情况下，向计费系统发送用户的漫游网络信息，供计费系统根据漫游网络信息对用户进行计费。
在一个例子中，国际关口局P-CSCF将携带PVNI头域的IMS初始注册消息传送到用户归属的S-CSCF，注册消息获取模块1001从S-CSCF获取携带PVNI头域的第三方IP短消息注册消息。
在一个例子中，注册消息获取模块1001收到用户的注册消息后，向HSS发送PUR消息，供HSS完成用户的注册，当IP-SM-GW收到HSS发送的PUA响应时，则说明用户注册成功，此时IP-SM-GW还需向S-CSCF返回注册响应。
进一步地，在采用离线计费的情况下，发送模块1003向计费系统发送携带用户的漫游网络信息的短消息话单文件，供计费系统根据用户的漫游网络信息对用户进行计费，即在运营商采用离线计费方式时，发送模块1003查询本地保存的主叫用户的注册信息，获取用户当前漫游网络信息中的包含MNC和MCC等信息的PLMNID，生成短消息话单文件；发送模块1003向计费系统传送带有MNC和MCC信息的短消息话单文件，供计费系统对漫游用户进行计费。
更进一步地，在采用在线计费的情况下，发送模块1003向在线计费系统发送携带用户的漫游网络信息的计费认证消息，供在线计费系统根据用户的漫游网络信息对用户进行实时计费。即在运营商采用在线计费方式时，IP-SM-GW查询本地保存的主叫用户的注册信息，获取用户当前漫游网络包含MNC和MCC等信息的PLMN ID；发送模块1003将用户拜访地的MCC和MNC信息添加到OCS系统的计费认证消息中，向OCS系统发送携带MNC和MCC信息的计费认证消息，供OCS系统进行漫游用户的实时计费。
本申请实施例提供的国际漫游短消息的计费装置，通过获取携带用户漫游网络信息的第三方注册消息并将注册消息存储在本地的信息列表中，使得当用户在发送国际漫游短消息时，能将用户的漫游地信息发送至短消息中心，从而短消息中心能够根据用户的漫游地信息对用户的国际漫游短消息进行计费，避免了用户在国际漫游情况下发送的短消息和未国际漫游情 况下发送的短消息在短消息中心生成的短消息计费话单完全相同的问题，实现了短消息中心对漫游短消息的计费。
不难发现，本实施方式为上述应用于IP-SM-GW的国际漫游短消息的计费方法实施例相对应的装置实施例，本实施方式可与上述应用于IP-SM-GW的国际漫游短消息的计费方法实施例互相配合实施。上述应用于IP-SM-GW的国际漫游短消息的计费方法实施例提到的相关技术细节在本实施方式中依然有效，为了减少重复，这里不再赘述。相应地，本实施方式中提到的相关技术细节也可应用在上述应用于IP-SM-GW的国际漫游短消息的计费方法实施例中。
本申请实施例还涉及一种国际漫游短消息的计费装置，应用于P-CSCF，如图11所示，包括：漫游网络信息获取模块1101、添加模块1102以及发送模块1103。
具体地说，漫游网络信息获取模块1101：在用于接收到用户发起的用户注册消息后，获取用户的漫游网络信息；添加模块1102：用于在用户注册消息中添加用户的漫游网络信息；发送模块1103：向S-CSCF发送漫游信息添加后的用户注册消息，供S-CSCF向IP-SM-GW发送第三方注册消息，其中，第三方注册消息中携带用户的漫游信息；第三方注册消息用于IP-SM-GW在收到用户发送的短消息的情况下，向计费系统发送用于对用户进行计费的漫游网络信息。
在一个例子中，漫游网络信息获取模块1101通过向用户归属网络的PCF/PCRF订阅漫游地运营商的PLMNID变更信息，来获取用户的漫游地信息。
在一个例子中，在收到国际漫游用户终端发送的IMS初始注册消息后，添加模块1102将获取到的用户漫游网络信息即PLMN ID信息，填写到注册消息的PVNI头域，其中，PLMN ID信息包括MCC和MNC信息。
在一个例子中，发送模块1103将用户漫游网络信息的IMS初始注册消息传送到用户归属的S-CSCF，S-CSCF将携带用户漫游网络信息的第三方IP短消息注册消息传送给IP-SM-GW。在漫游用户发送短消息时，IP-SM-GW将保存的MCC和MNC信息提供给计费系统，计费系统根据MCC和MNC信息进行离线或在线计费。
本申请实施例提供的国际漫游短消息的计费装置，通过在收到用户的短消息注册消息时，获取用户漫游网络信息，并将用户漫游网络信息添加到短消息注册消息中，并将携带用户漫游网络消息的注册消息发送至S-CSCF，供S-CSCF生成携带用户漫游网络信息的第三方注册消息并发送给IP-SM-GW，使得当用户在发送国际漫游短消息时，IP-SM-GW能将获取的用户漫游网络信息发送至短消息中心，从而短消息中心能够根据用户的漫游地信息对用户的国际漫游短消息进行计费，避免了用户在国际漫游情况下发送的短消息和未国际漫游情况下发送的短消息在短消息中心生成的短消息计费话单完全相同的问题，实现了短消息中心对漫游短消息的计费。
不难发现，本实施方式为上述应用于P-CSCF的国际漫游短消息的计费方法实施例相对应的装置实施例，本实施方式可与上述应用于P-CSCF的国际漫游短消息的计费方法实施例互相配合实施。上述应用于P-CSCF的国际漫游短消息的计费方法实施例提到的相关技术细节在本实施方式中依然有效，为了减少重复，这里不再赘述。相应地，本实施方式中提到的相关技术细节也可应用在上述应用于P-CSCF的国际漫游短消息的计费方法实施例中。
