Description

一种近距离业务的计费方法及通信装置 技术领域
本申请涉及无线通信技术领域，尤其涉及一种近距离业务的计费方法及通信装置。
背景技术
近距离业务(proximity based services，ProSe)是指终端设备之间利用无线通信技术进行相互发现以及直连通信的业务，近距离业务可包括近距离发现(ProSe discovery)和近距离通信(ProSe communication)两种。近距离业务可以用在很多场景下，例如，在商业场景中，利用近距离业务可以发现附近的餐厅，发现周围的好友；再例如，在安全场景下，救援队可以利用近距离业务在野外进行群组通信等。
近距离业务作为移动运营商提供的一种业务类型，终端设备在进行近距离业务的过程中的多种行为都会用到运营商的商业频谱，因此需要对终端设备使用近距离业务进行计费。
现有技术中，网络对于近距离发现业务采用事件计费的计费策略，这导致了终端设备只要成功申请了近距离发现业务就会被计费。但是实际上，终端设备可能在得到业务授权后没有进行近距离发现业务，例如因为本地没有用于近距离发现业务的频谱资源，或者作为监听者(monitor)的终端设备没有监听到它希望监听的作为广播者(announcer)的其他终端设备的信息，导致业务不成功。在这种情况下，仍然对终端设备进行计费是不合理的，因此用户体验也较差。
发明内容

需要说明的是，本申请实施例可以应用于上述图1所示的通信系统，不予限制；此外，本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”，可理解为一个或多个，例如理解为一个、两个或更多个。例如，包括至少一个，是指包括一个、两个或更多个，而且不限制包括的是哪几个。例如，包括A、B和C中的至少一个，那么包括的可以是A、B、C，A和B，A和C，B和C，或A和B和C。同理，对于“至少一种”等描述的理解，也是类似的。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度，并且“第一”、“第二”的描述也并不限定对象一定不同。
请参考图2，为本申请实施例提供的一种近距离业务的计费方法，该方法包括：
步骤S201、终端设备向AMF发送第一请求消息。
其中，该第一请求消息用于请求第一应用的近距离发现业务。
相应的，AMF接收来自终端设备的第一请求消息。
其中，第一应用可以为终端设备即将发起的一种应用业务，例如微信，大众点评等社交应用，也可以是各种游戏应用，例如王者荣耀、绝地求生等；相应地，第一应用的近距离发现业务可以为微信中发现附近的人，大众点评中发现同在一个商场、餐厅或场馆的用户，或者发现在附近区域内具有相同兴趣或分享相似内容的用户，游戏应用中发现附近区 域内其他具有相同人物形象的玩家等功能。
示例性地，当AMF授权该终端设备进行所述近距离发现业务后，终端设备可通过所述近距离发现业务发现其他终端设备，然后与发现的其他终端设备进行近距离通信业务，传输该第一应用的数据。
可选的，第一请求消息中还包括终端设备的标识信息和第一应用的标识信息。其中，终端设备的标识信息用于标识终端设备，例如可以是终端设备的设备标识(如设备序列号)，也可以是用户标识(如系统账号、手机号码、邮箱等)。第一应用的标识信息用于标识第一应用，例如可包括第一应用的名称，版本信息等。
具体地，第一请求消息可以为近距离发现请求(ProSe discovery request)消息，不限定。
需要指出的是，本申请也可以不限定终端设备请求某一具体应用的近距离发现业务，该近距离发现业务可以为泛指的(即不区分应用的)近距离发现业务。
步骤S202、AMF根据第一请求消息和第一计费策略，向终端设备发送第一响应消息。
其中，该第一响应消息用于表征授权终端设备进行所述近距离发现业务。该第一响应消息中包括该近距离发现业务的计费信息，该计费信息用于终端设备上报该近距离发现业务的统计信息。所述统计信息可以用于网络(如CHF)对该近距离发现业务进行计费，可以理解为是具体计费方法的输入参数或考量指标，因此，所述统计信息也可以称为计费输入信息，或计费指标信息，或计费参考信息，或具有其他名称，并不限定。
相应的，终端设备接收来自AMF的第一响应消息。
具体地，第一响应消息可以称为近距离发现响应(ProSe discovery response)消息，不限定。
步骤S203、终端设备根据计费信息，上报统计信息。
具体地，终端设备可根据计费信息，确定统计信息所包含的具体内容，进而上报统计信息。
在一个示例中，计费信息包括用于表征对所述近距离发现业务按照流量和/或时长进行计费的信息，例如计费信息可包括该近距离发现业务的计费方式，该计费方式可以包括按照流量计费的方式和按照时长计费的方式。相应的，统计信息可包括该近距离发现业务的流量和/或时长。进一步地，终端设备根据计费信息上报统计信息可以包括：若计费信息中包括的该近距离发现业务的计费方式包括按照流量计费的方式，则终端设备上报该近距离发现业务的流量，或者终端设备确定上报的统计信息中包括该近距离发现业务的流量；或者，若计费信息中包括的该近距离发现业务的计费方式包括按照时长计费的方式，则终端设备上报该近距离发现业务的时长，或者终端设备确定上报的统计信息包括该近距离发现业务的时长。
其中，近距离发现业务的流量和/或时长可以是终端设备在该近距离发现业务的过程中由该近距离发现业务消耗、占用或使用的流量和/或时长。
在另一个示例中，计费信息包括用于表征对所述近距离发现业务按照事件进行计费的信息，例如计费信息包括该近距离发现业务的计费方式，该计费方式包括按照事件计费的方式。相应的，统计信息可包括事件信息。
进一步地，终端设备根据计费信息上报统计信息可以包括：若计费信息中包括的该近距离发现业务的计费方式包括按照事件计费的方式，则终端设备上报在该近距离发现业务 过程中的事件信息，或者终端设备确定上报的统计信息包括在所述近距离发现业务过程中的事件信息。
其中，事件信息可包括终端设备在该近距离发现业务的过程中的业务角色和/或使用的公共陆地移动网络(public land mobile network，PLMN)资源。
终端设备在进行该近距离发现业务时的业务角色与其采用的近距离发现模型有关，例如，如果其采用的近距离发现模型为近距离直接发现模型A，则终端设备的业务角色可以是广播者(announcer)或监听者(monitor)；再例如，如果采用的近距离发现模型为近距离直接发现模型B，则终端设备的业务角色可以是发现者(discoverer)或被发现者(discoveree)。
上述PLMN资源可以包括终端设备在近距离发现业务过程中使用的频段信息、小区信息、无线技术类型、或运营商信息等信息中的一项或多项。
在本申请的实施例中，第一计费策略为终端设备的近距离发现业务对应的计费策略。
示例性地，在步骤S202中，AMF可根据第一请求消息和终端设备的签约数据，确定授权该终端设备进行所述近距离发现业务，然后AMF根据第一计费策略向终端设备发送第一响应消息。
进一步地，第一计费策略可以是AMF在确定授权终端设备进行所述近距离发现业务后，从本地或PCF获取的，并不限定。具体的，AMF从本地获取第一计费策略可以是指，AMF通过之前该终端设备的近距离发现业务的请求流程已从PCF获取了第一计费策略并保存到了本地，因此，AMF可从本地获取之前保存的第一计费策略。而AMF从PCF获取第一计费策略可以是指，AMF被配置为每次从PCF获取第一计费策略，以确保获取到的第一计费策略是最新的或准确的；或者，也可以是指当AMF确定本地没有保存第一计费策略时，或者本地保存的第一计费策略已过有效期时，从PCF获取第一计费策略。
应注意，第一计费策略可以是终端设备的第一应用的近距离发现业务所适用的计费策略，也可以是终端设备的所有应用的近距离发现业务都适用的计费策略，并不限定。换言之，网络侧(例如PCF)可以针对不同应用的近距离发现业务分别配置计费策略，也可以不区分应用，为所有应用的近距离发现业务配置统一的计费策略。此外，网络侧也可以对不同的终端设备的相同应用的近距离发现业务配置相同或不同的计费策略，也不限定。
在一种可能的实施方式中，AMF可在接收到来自终端设备的第一请求消息后，从UDM获取该终端设备的签约数据，根据该终端设备的签约数据对终端设备进行鉴权。鉴权通过后，AMF确定能够授权该终端设备进行所述近距离发现业务，或者说确定该终端设备有权限进行所述近距离发现业务。可选的，所述签约数据可以为该终端设备与近距离发现业务或与第一应用的近距离发现业务相关的签约数据。
进而，AMF可在授权终端设备进行所述近距离发现业务后，从PCF获取第一计费策略。示例性地，AMF从PCF获取计费策略的过程可以包括：首先，AMF向PCF发送计费策略请求消息，该计费策略请求消息中包括终端设备所请求的所述近距离发现业务的信息，以表示当前请求的是终端设备的所述近距离发现业务的计费策略。例如，所述计费策略请求消息可包括终端设备的标识信息、第一应用的标识信息或业务类型信息中的一项或多项，其中，业务类型信息用于表征终端设备当前请求的近距离业务是所述近距离发现业务。如此，PCF可接收来自AMF的计费策略请求消息，根据该计费策略请求消息，确定所述近 距离发现业务对应的第一计费策略，然后通过计费策略响应消息，将该第一计费策略发送给AMF。
可选的，在本申请的实施例中，计费信息是AMF根据第一计费策略生成的，例如AMF可根据第一计费策略，确定计费信息中包括业务信息(如业务的标识信息)、业务进行的时长、业务消耗的流量、进行业务的对象(如对端设备的标识信息)、业务进行的小区(如小区的标识信息)、采用的接入技术等信息中的一项或多项。
如此，在步骤S202中，AMF根据第一计费策略向终端设备发送第一响应消息可以包括：AMF根据第一计费策略生成计费信息，然后AMF向终端设备发送第一响应消息，该第一响应消息包括该生成的计费信息。应注意，计费信息中包含的内容与第一计费策略中包含的内容可以部分相同或完全相同，并不限定。
需要说明的是，第一响应消息可以通过携带上述计费信息来隐含地指示终端设备上报统计信息。示例性地，当第一响应消息携带有上述计费信息时，终端设备确定需要上报所述近距离发现业务的统计信息。
显然，第一响应消息中还可包括上报指示信息，该上报指示信息用于指示终端设备上报所述近距离发现业务的统计信息。于是，在步骤S203中，终端设备从AMF接收到第一响应消息后，可根据该上报指示信息和计费信息上报所述近距离发现业务的统计信息。
可选的，第一响应消息中还包括统计信息的上报条件，如此，终端设备可在该上报条件被满足时上报统计信息。
例如，统计信息的上报条件可以包括以下一项或多项：所述近距离发现业务的流量大于或等于第一门限值；所述近距离发现业务的时长大于或等于第二门限值。相应地，统计信息的上报条件被满足可以是指，所述近距离发现业务的流量大于或等于第一门限值，和/或，所述近距离发现业务的时长大于或等于第二门限值。
再例如，终端设备可以被设置为按照某一个设定的时间长度周期性地上报统计信息，如此，统计信息的上报条件被满足可以是指，周期性上报的定时器被触发。
应注意，上报条件可以是一个或多个上报条件，本申请对上报条件的数量不作具体限定。如果存在多个上报条件，终端设备可以被配置为，当多个上报条件中的任一上报条件满足时上报统计信息，也可以在当多个上报条件同时满足时上报统计信息，并不限定。
可选的，在本申请的实施例的一种实施场景中，上述方法还包括：终端设备向AMF上报统计信息，AMF接收到来自终端设备的统计信息后，再将统计信息发送给CHF，以便CHF对终端设备的所述近距离发现业务进行计费。
也可能的，由于终端设备的位置变化等原因，终端设备在满足上报条件时，已接入另一个AMF，则在该情形下，终端设备可以向新接入的AMF上报统计信息，由新接入的AMF将统计信息发送给CHF。
可选的，在本申请的实施例的另一种实施场景中，第一响应消息中还可包括CHF的地址，该CHF的地址用于终端设备向CHF上报统计信息。
进一步地，上述方法还包括：终端设备根据CHF的地址向CHF上报统计信息，以便CHF对终端设备的所述近距离发现业务进行计费，不再需要经过AMF转发统计信息，从而有效减小上报延时。
采用上述技术方案，网络可以基于流量、时长以及事件等一种或多种因素对终端设备 的近距离发现业务进行计费，从而解决现有技术中对近距离发现业务计费不合理的问题，有效提高用户体验。
本申请实施例中的技术方案既可以适用于对终端设备的近距离发现业务和近距离通信业务进行分别计费的场景下，也可以适用于对终端设备的近距离发现业务和近距离通信业务进行统一计费的场景下。所述统一计费指的是对于近距离通信和近距离发现两种近距离业务类型，采用相同的计费策略，比如都采用基于流量的计费。
下面对本申请实施例涉及的对终端设备的近距离发现业务和近距离通信业务进行统一计费的场景进行说明。
可选的，在上述实施例的另一种实施场景中，该场景用于对终端设备的近距离发现业务和近距离通信业务进行统一计费，第一请求消息中还包括第一信息。
在一种可能的实施方式中，该第一信息用于请求对近距离发现业务和近距离通信业务进行统一计费，即对于该终端设备的任何应用的近距离发现业务和近距离通信业务都可以采用统一计费。或者，该第一信息用于请求对第一应用的近距离发现业务和该第一应用的近距离通信业务进行统一计费，即针对某一个特定应用的近距离发现业务和近距离通信业务采用统一计费。
具体地，在该实施方式中，第一信息还可以称为统一计费请求信息，或具有其他名称，并不限定。在另一种可能的实施方式中，该第一信息可用于表征终端设备支持对近距离发现业务和近距离通信业务进行统一计费。
具体地，在该实施方式中，第一信息还可以称为终端设备的能力信息，或计费能力信息，或具有其他名称，并不限定。
基于上述两种可能的第一信息的实施方式，示例性地，AMF在接收到来自终端设备的第一请求消息后，可向PCF请求第一计费策略，并且在向PCF请求该第一计费策略时携带上述第一信息，或者说AMF向PCF发送的计费策略请求消息中可包括上述第一信息，该第一信息可以是上述任一种实施方式的第一信息。进而，PCF向AMF返回第一计费策略，该第一计费策略还可包括用于指示对近距离发现业务和近距离通信业务进行统一计费的指示信息。相应地，AMF向终端设备发送的计费信息中也可包括用于指示对近距离发现业务和近距离通信业务进行统一计费的指示信息。
在该场景中，为了便于对终端设备所请求的近距离发现业务进行计费，终端设备上报的统计信息中还可包括业务类型信息，该业务类型信息用于表征终端设备进行的近距离业务的业务类型具体为近距离发现业务。
采用上述技术方案，可实现对终端设备的近距离发现业务和近距离通信业务进行统一计费。通过进行统一计费可以有效简化网络侧的实现，减少对近距离发现业务和近距离通信业务进行分别计费带来的信令开销，此外还可以更贴近用户的业务付费习惯，提高用户体验。
本申请实施例中的技术方案还可适用于终端设备在脱网状态下进行近距离发现业务的场景中，所述脱网是指终端设备无法接入运营商网络，原因可能是例如运营商网络的信号覆盖弱、终端设备离开网络覆盖范围等。
下面对本申请实施例涉及的脱网场景进行说明。
可选的，在上述实施例的另一种实施场景中，该场景可以支持终端设备在脱网状态下进行近距离发现业务，第一请求消息中还包括第二信息，该第二信息用于终端设备请求在脱网状态下进行近距离发现业务。
示例性地，AMF在接收到第一请求消息后，可以根据终端设备的签约数据确定授权终端设备进行近距离发现业务，然后根据该第二信息确定终端设备请求在脱网状态下进行近距离发现业务，进而为该终端设备分配事务标识，并将该终端设备的事务标识通过第一响应消息发送给终端设备。
其中，事务标识用于在终端设备脱网后标识该终端设备，或者说用来在该终端设备脱网后追踪该终端设备，例如追踪其近距离发现业务的使用情况以用来计费等。
在该场景中，终端设备上报的统计信息中还可包括该终端设备的事务标识。
需要说明的是，终端设备在从脱网状态变为重新接入网络后，如果统计信息的上报条件被满足，则终端设备可通过当前接入的AMF向CHF上报所述统计信息，或者直接向CHF上报所述统计信息。此外，终端设备当前接入的AMF与终端设备在脱网前接入的AMF可以是同一AMF，也可以是不同的AMF，不作限定。
此外，AMF还可将该终端设备的事务标识发送给UDM，以便UDM保存该事务标识。
在一种可能的实施方式中，UDM可在该终端设备去注册后保留或不删除该终端设备的事务标识，从而便于对脱网的终端设备的用户上下文进行管理。
在另一种可能的实施方式中，AMF还可为该终端设备的事务标识分配对应的业务授权时间，并将该终端设备的事务标识以及该事务标识对应的业务授权时间发送给UDM，以便UDM保存该事务标识和对应的业务授权时间。进一步地，AMF可以通过上述第一响应消息将该事务标识和对应的业务授权时间发给终端设备。
其中，业务授权时间是指允许终端设备进行该近距离发现业务的时间长度。它可以是一个定时器timer，定时器的取值表示时长，单位可以是秒、分、时、或者年。
示例性地，UDM可在该终端设备的事务标识对应的业务授权时间到达前，不删除该终端设备的事务标识，而当超出业务授权时间之后，才删除该终端设备的事务标识。可选的，所述业务授权时间可以从终端设备脱网后(例如在终端设备完成去注册后)开始计时，也可以从为该终端设备生成事务标识时开始计时，不作限定。所述终端设备的事务标识对应的业务授权时间也可以理解为终端设备的事务标识的生存时间或有效时间。
由于在终端设备脱网后，UDM会删除该终端设备相关的用户信息，这会导致当终端设备脱网后，终端设备的用户上下文无法管理，进而无法对脱网的终端设备使用近距离发现业务进行计费。鉴于此，本申请的实施例中通过为该终端设备分配对应的事务标识，并相应保存到UDM以及下发给终端设备，可将终端设备在脱网前以及脱网后进行的近距离发现业务的相关信息关联起来，使得网络在该终端设备脱网后依然能够对该终端设备的用户上下文进行有效管理，从而实现对脱网用户的近距离发现业务的计费。
值得注意的是，本申请的各实施例中由AMF执行的动作或步骤，也可以由ProSe CTF来执行，即ProSe CTF可以具有与AMF类似的计费相关功能。
