一种邻近发现标识的使用方法、装置及存储介质
相关申请的交叉引用
本申请要求在2020年04月03日提交中国专利局、申请号为202010258452.5、申请名称为“一种邻近发现标识的使用方法、装置及存储介质”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
本申请涉及通信领域,尤其是涉及一种邻近发现标识的使用方法、装置及存储介质。
背景技术
在第四代移动通信(the fourth generation mobile network,4G)邻近通信业务(Proximity Service,ProSe)标准中,为支持受限发现(restricted discovery)过程,邻近业务功能(ProSe Function)向用户终端(User Equipment,UE)提供邻近发现标识(ProSe Discovery UE ID,PDUID),UE向应用服务器(ProSe Application Server)提供该PDUID。在后续的发现过程中,应用服务器使用该PDUID认证邻近业务功能发送的发现请求。
在第五代移动通信(the fifith generation mobile network,5G)ProSe标准中,为UE提供策略/参数的网络实体不再是ProSe Function而是策略控制功能(Policy Control Function,PCF)。由PCF为UE提供发现参数,而具体的发现过程由ProSe Function参与。即在5G ProSe中,参数提供功能和发现功能位于不同的网络实体,而在4G ProSe中,参数提供功能和发现功能位于同一网络实体(即ProSe Function),这使得在5G ProSe中不能使用与4G ProSe相同的方法来进行参数提供和功能发现。

具体实施方式
本申请实施列提供一种邻近发现标识的使用方法、装置及存储介质,以解决现有技术中存在的在5G网络架构下,如何为UE分配邻近发现标识,以及如何使用该邻近发现标识的技术问题。
本申请实施例中的技术方案为解决上述的技术问题,总体思路如下:
提供一种邻近发现标识的使用方法,应用于网络侧的策略控制功能PCF,该使用方法包括:从用户终端UE接收邻近业务策略提供请求消息;其中,邻近业务策略提供请求消息用于请求为UE提供进行邻近发现所需的参数;根据邻近业务策略提供请求消息,向UE提供邻近发现参数;其中,邻近发现参数包括UE的邻近发现标识。
由于在上述方案中,网络侧的策略控制功能PCF在接收到UE发送的邻近业务策略提供请求消息后,根据邻近业务策略提供请求消息所请求的为UE提供进行邻近发现所需的参数,并向UE提供邻近发现参数,该邻近发现参数中包括了UE的邻近发现标识。从而使得UE在5G网络架构下,能够使用邻近发现标识。
为了更好的理解上述技术方案,下面通过附图以及具体实施例对本申请技术方案做详细的说明,应当理解本申请实施例以及实施例中的具体特征是对本申请技术方案的详细的说明,而不是对本申请技术方案的限定,在不冲突的情况下,本申请实施例以及实施例中的技术特征可以相互组合。
为了是本领域的技术人员能够充分理解本申请的方案,在介绍本申请的技术方案之前,先简单的介绍4G ProSe标准中邻近发现标识的分配和使用。
在4G ProSe中,为支持受限发现过程,应用服务器需要认证邻近业务功能发送的发现请求,为了避免向发现服务器暴露UE的3GPP网络标识(如IMSI),邻近业务功能为UE分配一个PDUID。在业务授权过程中,邻近业务功能通过PC3接口将PDUID提供给UE。
在受限发现过程中,UE向应用服务器提供PDUID,应用服务器使用PDUID认证邻近业务功能的发现请求。具体过程请参见图1,为4G中邻近业务的受限发现过程的流程图。
步骤100:UE向应用服务器发送PDUID,并接收应用服务器为UE分配的RPAUID。
UE可以通过信令层向应用服务器提供PDUID,应用服务器为该PDUID分配RPAUID并保存PDUID与RPAUID的绑定关系,之后,应用服务器向UE返回RPAUID。
步骤101:UE向邻近业务功能发送发现请求消息。
该发现请求消息中包含RPAUID、Application ID等参数。
步骤102:邻近业务功能对UE进行授权检查。
该授权检查用于确定UE提供的Application ID是否被允许进行首先发现。 如果邻近业务功能中没有UE上下文(UE context),邻近业务功能通过归属签约用户服务器(Home Subscriber Server,HSS)进行授权检查。
步骤103:邻近业务功能向应用服务器发送认证请求消息。
该认证请求消息中包含RPAUID。
步骤104:应用服务器根据存储的PRAUIDA与PDUID的绑定关系,确定与认证请求消息中包含的RPAUID对应的PDUID。
步骤105:应用服务器通过验证响应消息,将与认证请求消息中包含的RPAUID对应的PDUID返回给邻近业务功能。
步骤106:邻近业务功能验证应用服务器返回的PDUID与UE的PDUID是否相同,在确定相同时,为RPAUID分配邻近发现应用层用户标识(ProSe Restricted Code)以及其它参数。
步骤107:邻近业务功能向UE返回发现响应消息,该发现响应消息中携带ProSe Restricted Code以及其它参数。
步骤108:UE在空口广播邻近发现应用层用户标识。
这样UE就可以通过邻近发现应用层用户标识让其它UE发现它,并与之进行邻近通信。
通过步骤100-108可以看出,在4G ProSe标准中,邻近业务功能(ProSe Function)既为UE提供邻近发现标识,又参与到具体的发现过程中,实现邻近业务发现功能(ProSe Function)与应用服务器(ProSe App Server)之间的认证过程。
而在5G ProSe标准中,由PCF为UE提供发现参数,而具体的发现过程由邻近业务功能参与。即在5G ProSe中,参数提供功能和发现功能位于不同的网络实体,而在4G ProSe中,参数提供功能和发现功能位于同一网络实体(即ProSe Function),这使得在5G ProSe中不能使用与4G ProSe相同的方法来进行参数提供和功能发现。
因此,本申请提供了下述方法来解决:在5G网络架构下,不能使用邻近发现标识的问题。
请参考图2,本申请实施例提供一种邻近发现标识的使用方法,应用于网络侧的策略控制功能PCF,该使用方法的处理过程为:
步骤201:从用户终端UE接收邻近业务策略提供请求消息;其中,邻近业务策略提供请求消息用于请求为UE提供进行邻近发现所需的参数。
从UE接收邻近业务策略提供请求消息,还包括:从UE接收邻近发现能力信息;其中,邻近发现能力信息用于指示UE支持邻近业务发现。
例如,在UE向PCF发送邻近业务策略提供请求消息时,邻近业务策略提供请求消息中可以携带邻近业务能力信息。通过邻近业务能力信息可以指示UE支持受限发现。
在实际应用中,邻近业务策略提供请求消息可以是通过接入控制和移动性管理功能(access control and mobility management Function,AMF)转发给PCF的。AMF可以根据UE的能力信息和签约信息确定UE是否可以进行受限发现,在确定UE能进行受限发现时,将邻近业务策略提供请求消息转发给PCF。
在PCF接收到邻近业务策略提供请求消息后,便可执行步骤202。
步骤202:根据邻近业务策略提供请求消息,向UE提供邻近发现参数;其中,邻近发现参数包括UE的邻近发现标识。
UE在接收到邻近业务策略提供请求消息后,需要根据该邻近业务策略提供请求消息为UE分配策略参数和邻近发现标识(PDUID),并将之作为邻近发现参数提供给UE。
为UE分配邻近发现标识时,可以采用以下两种方式:
第一种,由PCF为UE分配邻近发现标识,并提供给UE。
第二种,PCF从邻近发现功能获取邻近发现标识,并提供给UE。
PCF从邻近发现功能获取邻近发现标识,可以采用下列方式获取邻近发现标识:PCF请求邻近发现功能分配邻近发现标识,并在请求消息中包含UE的UE标识;PCF接收邻近发现功能为UE分配的邻近发现标识。
UE标识可以是UE ID,如订阅标识符(Subscription Permanent Identifier, SUPI)。
在本申请提供的实施例中,邻近发现标识包括公共陆地移动网标识(Public Land Mobile NetworkIdentifier,PLMN ID)和UE的临时标识。
在本申请提供的实施例中,向UE提供邻近发现参数之后,还包括:
PCF接收邻近发现功能的认证请求消息,认证请求消息包含UE的UE标识;PCF向邻近发现功能返回认证响应消息,响应消息包含UE的邻近发现标识。
在PCF向UE提供邻近发现参数之后的受限发现过程中,PCF还可能需要向邻近发现功能提供UE的邻近发现标识,如PCF接收到邻近发现功能发送的包含UE标识的认证请求消息后,PCF根据UE标识找出与之对应的邻近发现标识,并将该邻近发现标识通过认证响应消息发送给邻近业务功能。
为了使本领域的技术人员能够充分理解上述技术方案,下面将提供2个具体的例子进行说明:
请参见图3为本申请实施提供的PCF为UE分配邻近发现标识的流程图。
步骤301:PCF接收邻近业务策略提供请求消息。
该邻近业务策略提供请求消息用于请求为UE提供进行邻近发现所需的参数,该邻近业务策略提供请求消息中还包括用于指示UE支撑邻近业务发现的邻近发现能力信息。
步骤302:PCF根据邻近业务策略为UE提包含供策略参数和邻近发现标识的邻近发现参数。
步骤303:PCF向UE发送邻近发现参数。
在执行完步骤301~303之后,在后续的发现过程中,UE请求邻近业务功能为其分配邻近发现码的过程中,由于是PCF为UE分配的邻近发现标识,所以在邻近业务功能中并未存储有UE标识对应的邻近发现标识,因此邻近业务功能需要向PCF发送包含UE标识的认证请求消息,以便PCF将与UE标识对应的邻近发现标识通过认证响应消息返回给邻近业务功能。
请参见图4为本申请实施例提供的邻近业务功能分配邻近发现标识的流 程图。
步骤401:PCF接收邻近业务策略提供请求消息。
该邻近业务策略提供请求消息用于请求为UE提供进行邻近发现所需的参数,该邻近业务策略提供请求消息中还包括用于指示UE支撑邻近业务发现的邻近发现能力信息。
步骤402:PCF发送包含UE标识的请求消息给邻近业务功能。
该请求消息用于请求邻近业务功能为UE标识对应的UE分配邻近发现标识。
步骤403:邻近业务功能根据请求消息为U分配对应的邻近发现标识。
同时,存储UE标识与邻近业务标识的对应关系。
步骤404:PCF接收邻近发现标识。
步骤405:PCF根据邻近业务策略为UE提包含供策略参数,将策略参数和邻近发现标识作为邻近发现参数。
步骤406:PCF发送邻近发现参数给UE。
由于邻近业务功能中存储了邻近业务标识,所以在后续的发现过程中,邻近业务功能在为UE分配邻近发现标识码时,便可以直接在邻近业务功能中查找与UE标识对应的邻近发现标识,而不需请求PCF提供。
在从PCF侧介绍了邻近发现标识的使用方法之后,下面将从邻近业务发现功能侧介绍如何使用PCF为UE分配的邻近发现标识。
请参见图5,本申请一实施例中提供一种邻近发现标识的使用方法,应用于网络侧的邻近业务发现功能,该方法包括:
步骤501:接收用户终端UE发送的发现请求消息,发现请求消息中包含UE的UE标识和邻近发现应用层用户标识,邻近发现应用层用户标识是应用服务器根据策略控制功能PCF为UE提供的邻近发现标识分配的。
在UE接收到PCF为其提供的邻近发现标识后,UE通过应用层信令向应用服务器提供UE的邻近发现标识,使应用服务器为UE分配邻近发现应用层用户标识。在UE获得邻近发现应用层用户标识后,向邻近业务发现功能发送 携带有UE标识和邻近发现应用层用户标识的发现请求消息。
邻近业务功能接收到UE发送的发现请求消息后,便可执行步骤502。
步骤502:获取UE的邻近发现标识。
在本申请提供的实施例中,获取UE的邻近发现标识可以采用以下方式:
若邻近发现标识是邻近发现功能为UE分配的,则根据UE标识在邻近发现功能中获取邻近发现标识。
若邻近发现标识是策略控制功能PCF为UE分配的,当发现请求消息中包括邻近发现标识时,则从发现请求消息中获取邻近发现标识;当发现请求消息中不包括邻近发现标识时,则根据UE标识从PCF获取邻近发现标识。
邻近业务功能根据UE标识从PCF获取邻近发现标识,可以采用如下方式实现:
向PCF发送认证请求消息,认证请求消息中包含UE标识;接收PCF返回的认证响应消息,响应消息中包含邻近发现标识。
在获取UE的邻近发现标识之后,便可执行步骤503。
步骤503:向UE发送发现响应消息,发现响应消息中包含邻近发现应用层用户标识对应的邻近发现标识码。
为了使本领域的技术人员能够充分理解上述方案,下面将提供几个具体的例子进行说明:
请参见图6为本申请实施例提供的邻近业务发现过程的流程图一,假设UE向邻近发现功能提供了邻近发现标识,UE的邻近发现标识是采用图3中的方式分配的。
600:UE向应用服务器发送邻近发现标识,并接收应用服务器为UE分配的邻近发现应用层用户标识。
该邻近发现标识是由PCF分配的,具体的分配过程请参见图3。
601:邻近业务功能接收包含邻近发现标识和邻近发现应用层用户标识的发现请求消息。
该发现请求消息用于让邻近业务功能为UE分配邻近发现标识码。
602:对UE的应用进行授权检查。
邻近业务功能在接收到发现请求消息后,需要对UE的应用是否被运行进行受限发现进行检查(即授权检查)。若邻近业务功能中有UE上下文则在邻近业务功能中进行授权检查,若邻近业务功能中没有UE上下文则执行步骤602a。
602a:若邻近业务功能中没有UE上下文,则通过PCF进行授权检查。
在授权检查通过后,便可执行步骤603。
603:邻近业务功能向应用服务器发送包含邻近发现应用层用户标识的请求消息。
604:应用服务器根据邻近发现应用层用户标识找到对应的邻近发现标识。
605:应用服务器返回邻近发现标识。
606:邻近业务功能从发现请求消息中获取邻近发现标识,并判断其与应用服务器返回的邻近发现标识是否相同,若相同为UE分配邻近发现标识码。
607:邻近业务功能向发送UE包含邻近发现标识码的发现响应消息。
608:UE在空口广播邻近发现标识码。
请参见图7为本申请实施例提供的邻近业务发现过程的流程图二,假设UE未向邻近发现功能提供邻近发现标识,UE的邻近发现标识是采用图3中的方式分配的。
700:UE向应用服务器发送邻近发现标识,并接收应用服务器为UE分配的邻近发现应用层用户标识。
该邻近发现标识是由PCF分配的,具体的分配过程请参见图3。
701:邻近业务功能接收包含邻近发现标识和邻近发现应用层用户标识的发现请求消息。
该发现请求消息用于让邻近业务功能为UE分配邻近发现标识码。
702:邻近业务功能发送包含UE标识的认证请求消息。
703:PCF获取与UE标识对应的邻近发现标识。
由于邻近业务标识是PCF为UE分配的,所以PCF可以根据邻近业务功 能提供的UE标识,获取对应的邻近业务标识。
704:邻近业务功能从PCF接收返回的包含邻近发现标识的认证响应消息。
705:邻近业务功能向应用服务器发送包含邻近发现应用层用户标识的请求消息。
706:应用服务器根据邻近发现应用层用户标识找到对应的邻近发现标识。
707:应用服务器返回邻近发现标识。
708:邻近业务功能判断PCF返回的邻近发现标识与应用服务器返回的邻近发现标识是否相同,若相同为UE分配邻近发现标识码。
709:邻近业务功能向发送UE包含邻近发现标识码的发现响应消息。
710:UE在空口广播邻近发现标识码。
请参见图8为本申请实施例提供的邻近业务发现过程的流程图三,假设UE未向邻近发现功能提供了邻近发现标识,UE的邻近发现标识是采用图4中的方式分配的。
800:UE向应用服务器发送邻近发现标识,并接收应用服务器为UE分配的邻近发现应用层用户标识。
该邻近发现标识是由邻近业务功能分配的,具体的分配过程请参见图4。
801:邻近业务功能接收包含邻近发现标识和邻近发现应用层用户标识的发现请求消息。
该发现请求消息用于让邻近业务功能为UE分配邻近发现标识码。
802:邻近业务功能向应用服务器发送包含邻近发现应用层用户标识的请求消息。
803:应用服务器根据邻近发现应用层用户标识找到对应的邻近发现标识。
804:应用服务器返回邻近发现标识。
805:邻近业务功能从本地获取与UE标识对应的发现标识,并判断从本地获取的邻近发现标识与应用服务器返回的邻近发现标识是否相同,若相同为UE分配邻近发现标识码。
由于UE的邻近发现标识是由邻近业务功能分配的,所以邻近业务功能可 以从本地获取与UE标识对应的邻近发现标识。
806:邻近业务功能向发送UE包含邻近发现标识码的发现响应消息。
807:UE在空口广播邻近发现标识码。
在从PCF侧及邻居业务应用侧介绍完邻近发现标识的使用过程后,接下来从UE侧介绍邻近发现标识的使用过程。
