具体实施方式
本申请提供一种数据处理的方法、装置和系统，用于在组通信中，接入网设备为组控制设备保存组成员设备的V2X通信参数，并依据保存的V2X通信参数成功为组成员设备分配PC5资源，使得组成员设备可以在分配的PC5资源上进行V2X业务。
首先，本申请实施例提供的数据处理的方法可以应用于各种通信系统，例如，可以应用于5G通信系统。以下以5G通信系统为例，对本申请实施例提供的数据处理的方法的具体应用场景进行说明。
示例性的，本申请提供的数据处理方法应用的网络架构可以如图1所示，图1为基于5G通信技术的第三代合作伙伴计划(3rd generation partnership project，3GPP)网络架构。
其中，该网络架构具体可以包括但不限于：无线接入网(radio access network，RAN)设备、AMF实体、用户面功能(user plane function，UPF)实体、PCF实体、用户设备(user equipment，UE)等，且各个网元或设备的数量可以是一个或多个，图1中仅以1个进行举例说明。
AMF实体，主要负责终端设备的认证、终端设备的移动性管理、网络切片选择、会话管理功能(session management function，SMF)实体的选择等功能。
PCF实体，主要负责提供策略规则给网络实体。
RAN可以由多个RAN设备组成的网络，实现无线物理层功能、资源调度和无线资源管理、无线接入控制以及移动性管理功能等。RAN设备通过用户面接口N3与UPF实体相连，用于传输终端设备的数据。RAN设备通过控制面接口N2和AMF实体建立控制面信令连接，用于实现无线接入承载控制等功能。其中，本申请图1中示出了无线接入网设备，即RAN设备，也可以替换为有线的接入网设备，图1中仅以RAN设备进行示例性说明，在本申请以下的说明中，直接称为接入网设备。具体的，接入网设备可以是具有中心控制功能的设备，如宏基站、微基站、热点(pico)、家庭基站(femeto)、传输点(TP)、中继(Relay)、接入点(Access Point，AP)等。若该接入网设备为基站，该基站可以是，长期演进(long term evolution，LTE)中的基站(eNodeB，eNB)，新空口(New Radio，NR)中的基站(gNodeB，gNB)等。
UE，用于向用户提供语音/数据连通性，例如，具有无线连接功能的手持式设备、或车载设备等。也可以包括智能移动电话、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等等，以下也可以称为终端设备。
UPF实体，作为协议数据单元(protocol data unit，PDU)会话连接的锚定点，负责对用户设备的数据报文过滤、数据传输/转发、速率控制、生成计费信息等。
此外，除了图1中所包括的网元之外，该网络架构还可以包括其他网元(图中未示出)，例如，鉴权服务器功能(Authentication Server Function，AUSF)、网络切片选择功能(Network Slice Selection Function，NSSF)、会话管理功能(Session Management Function，SMF)等等，本申请实施例仅仅是示例性说明，具体可以根据实际应用场景进行调整。
进一步地，本申请提供的数据处理方法具体可以应用于V2X通信中，具体的应用场景可以如图2所示。
其中，5G核心网主要可以包括但不限于PCF实体、AMF实体、SMF实体、UPF实体、统计数据管理网元(unified data management，UDM)网元、统一数据存储库网元(unified data repository，UDR)网元、网络能力开放功能网元(network exposure function，NEF)网元和应用功能(application function，AF)实体等。
PCF实体、AMF实体、RAN设备、UPF实体以及UE的介绍如前述图1中的描述，此处不 再赘述。
UDM网元，主要是管控用户数据。例如，签约信息的管理，可以包括：从UDR网元获取签约信息并提供给其它网元(例如AMF实体)、为终端设备生成3GPP的认证凭证和登记维护当前为终端设备服务的网元。
UDR网元，主要用于存储用户数据。用户数据可以包括由UDM网元调用的签约数据，PCF实体调用的策略信息，用于能力开放的结构化数据，NEF网元调用的应用数据。
NEF网元，用于连接核心网其它内部网元与核心网外部应用服务器之间的交互，以将网络能力信息提供给外部应用服务器，或者将外部应用服务器的信息提供给核心网网元。
SMF实体，主要负责UE会话管理的控制面功能，包括UPF选择，IP地址分配，会话的QoS管理，(从PCF)获取策略控制和计费(Policy Control and Charging，PCC)策略等。
AF实体，具备应用服务功能，与核心网网元交互以为终端设备提供服务。例如，与PCF实体交互以进行业务策略控制，或者，与NEF网元交互以获取网络能力信息或提供应用信息给网络，或者，与PCF实体交互以提供数据网络接入点信息给PCF实体，用以PCF实体生成相应的数据业务的路由信息。
其中，一个或多个UE可以通过Uu接口接入RAN设备(如图2中的U11、UE2)，并且，两个或两个以上的UE之间也可以建立连接。例如，如图2所示，UE1与UE2之间可以通过邻近通信第五接口(ProSe communication 5，PC5)接口建立连接，具体可以是独立的信令连接、组通信(group communication)连接等等。
V2X通信包括PC5通信以及Uu通信，即V2X业务可以通过Uu接口或PC5接口与数据网络(Data Network)中的V2X应用服务器进行通信。通常，Uu接口通信与PC5接口通信可以使用不同的频段，因此，Uu接口通信与PC5接口通信可以同时进行。
需要说明的是，本申请实施例的数据处理方法可以应用于图1或图2所示的通信网络，也可以应用于3G，或4G通信网络，还可以应用于未来通信网络，例如，6G网络、7G网络等，且上述涉及的网元名称不限定，均可以替换成在未来通信网络中具备相同或相似功能的网元名称，本申请并不做限定。
基于前述图1与图2的网络架构，本申请提供的数据处理的方法可以应用于组通信(group communication)的场景。示例性地，组通信的具体场景可以参阅图3。
组通信为多个UE之间建立的通信连接。其中一个UE可以作为组控制设备(group controller)，其他的一个或多个UE作为组成员(Group member)设备。例如，图3中的组成员设备1、组成员设备2以及组成员设备3。
组控制设备可以对组通信组内的各个组成员进行管理，例如，可以对各个组成员的进行部分V2X业务管理、数据管理、资源分配等等。通常，在组通信场景中，组成员设备不需要直接向接入网设备请求PC5资源，而是由组控制设备为组成员设备的PC5通信向组控制器对应的接入网设备请求PC5资源。
例如，若组通信内包括4个UE，UE1、UE2、UE3以及UE4，则可以将UE1作为组控制设备，UE2、UE3以及UE4作为组成员设备。UE1可以为UE2、UE3以及UE4向UE1对应的接入网设备请求PC5资源。
具体的，组成员设备与组控制设备之间可以通过Uu口或者PC5口建立连接。并且，在组成员设备与组控制建立组通信连接时，组成员设备可以处理空闲态，即组成员设备不存在与通信网络(接入网或核心网)的信令连接。
应理解，组成员是组通信中接入组控制器的成员，组成员可以以UE为载体。在本申请以下的说明中，与组控制设备建立组通信连接的设备可以直接称为组成员，也可以称为组成员设备。
下面基于前述图1与图2的网络架构或图3的应用场景，对本申请提供的数据处理的方法进行说明。
请参阅图4，本申请实施例提供了一种数据处理方法，具体如下所述。
401、接入网设备接收组成员设备的V2X通信参数。
其中，该接入网设备为组控制设备接入的接入网设备，后续可以称之为组控制设备的接入网设备。此外，组成员设备接入的接入网设备与组控制设备接入的接入网设备可以是同一个，也可以不相同。
并且，在接入网设备接收组成员设备的V2X通信参数之前，组控制设备与组成员设备之间的连接状态，可以是已建立连接，也可以是未建立连接，具体可以根据实际应用场景进行调整，本申请对此不作限定。
在一种具体的实施方式中，接入网设备在接收V2X通信参数时，可以同时接收组成员的标识、组控制设备的标识、或者组标识中的一种或多种标识，该一种或多种标识，用于接入网设备确定V2X通信参数对应的组成员设备，以及该组成员所属的组以及所属组中的组控制设备等。
其中，V2X通信参数可以包括组成员设备的V2X授权信息，组成员设备的PC5接口通信的服务质量(quality of service，QoS)参数等中的至少一种。例如，V2X通信参数也可以仅包括组成员设备的V2X授权信息，也可以同时包括组成员设备的V2X授权信息以及PC5接口通信的QoS参数。V2X授权信息可以用于指示组成员设备是否可以使用V2X业务进行通信。PC5接口通信的QoS参数用于指示组成员设备可以在PC5接口通信中所使用的QoS参数。该Qos参数可以包括以下的一种或多种：PC5服务质量标识(PC5 QoS indentifier，PQI)，用于指示组成员设备的QoS要求；PC5优先级信息(例如PC5地址解析协议(Address Resolution Protocol,ARP)或PC5 priority，用于指示PC5资源调度的优先级)；PC5保障流比特率(guaranteed flow bite rate，GFBR)；PC5最大流比特率(maximum flow bite rate，MFBR)；PC5 QoS流标识(PC5 QoS flow identifer，PFI)等。
在一种实施方式中，接入网设备接收来自PCF实体的组成员设备的V2X通信参数。
在另一种实施方式中，接入网设备接收来自组控制设备的组成员设备的V2X通信参数。接入网可以直接接收来自组控制设备的组成员设备的V2X通信参数，无需经由PCF实体发送，可以提高接收到组成员设备的V2X通信参数的效率。
需要说明的是，V2X通信参数除了可以由PCF实体或者组控制设备发送之外，还可以是由其他可以获取到或者保存了组成员设备的V2X通信参数的设备发送，具体可以根据实 际应用场景进行调整，本申请对此不作限定。
402、接入网设备将V2X通信参数保存在组成员设备所属组中的组控制设备的上下文中。
其中，接入网设备在接收到组成员设备的V2X通信参数之后，为组成员所属组中的组控制设备保存该组成员设备的V2X通信参数，具体是保存在该组控制设备的上下文中。
需要说明的是，除了保存在组控制设备的上下文中，也可以是保存在其他与组控制设备对应的数据中，具体可以根据实际应用场景进行调整。
更具体的，可以是保存在接入网设备的本地存储设备或本地存储器中。
在一种实施方式中，接入网设备在组控制设备的上下文中保存了组成员设备的V2X通信参数之后，接入网设备根据组成员设备的V2X通信参数，为所述组成员设备分配PC5资源，并向所述组控制设备发送为组成员设备分配的PC5资源的信息。
在另一种具体的实施方式中，接入网设备接收来自组控制设备的PC5资源请求消息，该PC5资源请求消息用于请求为所述组成员设备分配PC5资源，接入网设备根据该PC5资源请求消息和保存的组成员设备的V2X通信参数，为该组成员设备分配PC5资源。
在一种实施方式中，接入网设备在接收到PC5资源请求消息之后，确定该PC5资源请求消息用于请求为组成员设备分配PC5资源，则接入网设备根据保存的V2X通信参数，对组成员设备进行授权检查。当确认授权成功时，接入网设备为组成员设备分配PC5资源，并向组控制设备发送为组成员分配的PC5资源的信息。为组成员分配的PC5资源可以用于组成员设备进行V2X业务，使得V2X业务正常进行。
在另一种具体的实施方式中，该PC5资源请求包括以下至少一种：组成员设备的组成员标识号、PC5接口通信服务质量标识(PQI)、PC5接口Qos流标识或数据量等。
在一种实施方式中，在接入网设备接收来自组控制设备的PC5资源请求消息之前，接入网设备还接收组成员设备的组成员识别号。该组成员识别号用于接入网设备识别组成员设备。
在另一种实施方式中，在接入网设备接收来自组控制设备的PC5资源请求消息之前，接入网设备可以为组成员设备分配组成员识别号，并向组控制设备发送该组成员识别号。以使组控制设备在为组成员请求PC5资源的PC5资源请求中可以携带该组成员识别号。
在一种实施方式中，若接入网设备接收来自组控制设备的V2X通信参数，则在接入网设备接收到该V2X通信参数之后，向PCF实体发送验证信息，该验证信息用于指示PCF实体验证组成员设备的V2X通信参数。在PCF实体对该V2X通信参数进行验证之后，向接入网设备发送验证回复消息。接入网设备接收来自PCF实体的验证回复信息，当验证回复信息用于指示组成员设备的V2X通信参数验证成功时，接入网设备保存V2X通信参数。因此，本申请实施方式中，接入网设备在接收到来自组控制设备的组成员设备的V2X通信参数之后，可以对该V2X通信参数进行验证，以保存正确的组成员设备的V2X通信参数。
在一种具体的实施方式中，接入网设备可以接收组控制设备的无线资源控制(Radio Resource Control，RRC)消息，该RRC消息中可以包括组成员设备的V2X通信参数。
在一种具体的实施方式中，该验证信息中包括来自组控制设备的V2X通信参数以及组 成员设备的标识。以使PCF实体可以识别出该V2X通信参数对应的组成员设备，并对该V2X通信参数进行验证。
在一种具体的实施方式中，接入网设备还向PCF实体发送指示信息，该指示信息用于指示组成员设备与组控制设备已建立连接。具体的，在组成员设备与组控制设备建立了连接之后，接入网设备向PCF实体发送该指示信息，以通知PCF实体该组控制设备与该组成员设备建立了连接。
在另一种实施方式中，若该验证回复信息指示组成员设备的V2X通信参数验证未成功，则接入网设备不保存该V2X通信参数。
在另一种实施方式中，若该验证回复信息指示组成员设备的V2X通信参数验证未成功，则PCF实体还可以将组成员设备正确的V2X通信参数发送至接入网设备。
因此，在本申请实施例中，接入网设备可以保存组成员设备的V2X通信参数，接入网设备在接收到来自组控制设备的PC5资源请求消息之后，为组成员设备请求PC5资源时，可以根据组成员设备的V2X通信参数，为组成员设备分配PC5资源。使得组成员设备可以根据分配的PC5资源进行V2X业务的PC5接口通信。可以避免因接入网设备上未保存组成员设备的V2X通信参数，而导致无法为组成员设备分配PC5资源，使得组成员设备无法使用PC5资源进行V2X业务的数据传输。
在图4的实施例中，接入网设备接收到的组成员设备的V2X通信参数可以是来自PCF实体，也可以来自组控制设备，下面对这两种情况进行进一步说明。
首先对PCF实体发送该V2X通信参数的实施例进行说明。请参阅图5，本申请实施例还提供了另一种数据处理方法，具体如下所述。
501、PCF实体获取组成员设备的V2X通信参数。
其中，该PCF实体为组控制设备对应的PCF实体，组控制设备与组成员设备可以对应同一个PCF实体，也可以对应不同的PCF实体。
当组控制设备与组成员设备对应同一个PCF实体时，该PCF实体可以从本地存储的数据中，获取组成员设备的V2X通信参数，或者接收组控制设备对应的UDR发设的组成员设备的V2X通信参数。
当组控制设备与组成员设备对应不同的PCF实体时，组成员设备对应的PCF实体从组成员设备对应的UDR获取组成员设备对应的V2X通信参数，然后组成员设备对应的PCF实体将该组成员设备的V2X通信参数发送至组控制设备对应的PCF实体。
需要说明的是，当组控制设备与组成员设备对应不同的PCF实体时，需要由组成员设备对应的PCF实体将组成员设备相关的数据发送至组控制设备对应的PCF实体。本申请的以下实施例中，以组控制设备对应的PCF实体进行说明，对于组控制设备与组成员设备对应不同的PCF实体时的场景不再赘述。
在一种实施方式中，在PCF实体获取组成员设备的V2X通信参数之前，PCF实体可以接收指示信息，该指示信息用于指示组成员设备与组控制设备已建立连接。PCF实体根据接收到的指示信息，获取该V2X通信参数。
具体的，PCF实体可以根据该指示信息，获取本地存储的组成员设备的V2X通信参数。 或者，PCF实体根据该指示信息，接收来自UDR的组成员设备的V2X通信参数。
在一种具体的实施方式中，PCF实体可以接收来自应用服务器(application server，AS)的指示信息，也可以接收来自组控制设备的指示信息，也可以接收来自组成员设备的指示信息，还可以接收来自接入网设备的指示信息等。
在一种实施方式中，在PCF实体获取组成员设备的V2X通信参数之后，根据该V2X通信参数对该组成员进行授权检查，当组成员设备授权成功时，PCF实体将组成员设备与组控制设备关联起来。
502、PCF实体向接入网设备发送组成员设备的V2X通信参数。
其中，在PCF实体获取到组成员设备的V2X通信参数之后，将该组成员设备的V2X通信参数发送至接入网设备。
在一种实施方式中，PCF实体还可以将组成员设备的V2X通信参数发送给组控制设备，组控制设备保存该组成员设备的V2X通信参数，以使组控制设备也可以对组成员设备进行授权检查，减少接入网设备的工作量。
在一种实施方式中，PCF实体还从组控制设备接收组成员设备的组成员识别号；或者，PCF实体从组成员设备接收组成员设备的组成员识别号；或者，PCF实体为组成员设备分配组成员识别号。该组成员识别号可以在组控制设备为组成员设备请求PC5资源时使用。
在一种实施方式中，PCF实体还向接入网设备发送组成员识别号，以使接入网设备可以根据该组成员识别号，识别出待分配PC5资源的组成员设备。
在另一种实施方式中，若组成员识别号由PCF实体分配，则在PCF实体为组成员设备分配了组成员识别号之后，PCF实体还向组成员设备发送该组成员识别号，或者，PCF实体向组控制设备发送该组成员识别号，或者，PCF实体向AS发送该组成员识别号。
503、接入网设备在组控制设备的上下文中保存组成员设备的V2X通信参数。
其中，在接入网设备接收到来自PCF实体的组成员设备的V2X通信参数之后，在组控制设备的上下文中保存该V2X通信参数。以使接入网设备可以基于该组成员设备V2X通信参数为组成员设备分配PC5资源。
需要说明的是，本申请实施例中的步骤503与前述步骤402中所述的过程类似，具体此处不再赘述。
在本申请实施例中，PCF实体在获取到组成员设备的V2X通信参数之后，将该V2X通信参数发送给接入网设备，以使接入网设备可以在组控制设备的上下文中保存组成员设备的V2X通信参数。接入网设备可以根据保存在组控制设备的上下文中的组成员设备的V2X通信参数，为组成员设备分配PC5资源。使得组成员设备可以根据分配的PC5资源进行V2X业务的PC5接口通信。可以避免因接入网设备上未保存组成员设备的V2X通信参数，而导致无法为组成员设备分配PC5资源，使得组成员设备无法使用PC5资源进行V2X业务的数据传输。
在由PCF实体向接入网设备发送组成员设备的V2X通信参数的场景下，可以是由组控制设备向PCF实体发送指示信息，以触发PCF实体向接入网设备发送组成员设备的V2X通信参数。请参阅图6，本申请实施例还提供了另一种数据处理方法，具体如下所述。
601、组成员设备与组控制设备建立连接。
其中，组成员设备与组控制设备之间可以建立组通信连接，或者其他的信令连接。
当组成员设备与组控制设备之间建立了组通信连接，该组通信连接可以参阅前述图3中的组通信连接的描述。
当组成员设备与组控制设备建立了其他的信令连接，该信令连接为组成员设备与组控制设备之间一对一的信令连接。
示例性地，组控制设备与组成员设备之间建立的连接可以参阅前述图3。
602、组控制设备向PCF实体发送指示信息。
其中，在组成员设备与组控制设备之间建立了连接之后，组控制设备可以向PCF实体发送指示信息。该指示信息用于指示组控制设备与组成员设备已建立连接。
在一种实施方式中，组控制设备通过AS向PCF实体发送该指示信息。具体的，组控制设备在与组成员设备建立连接之后，向AS发送指示信息，AS将该指示信息转发给PCF实体。或者，组控制设备在与组成员设备建立连接之后，向AS发送指示信息，AS根据该指示信息，生成不同格式的指示信息，然后将该不同格式的指示信息发送给PCF实体。
603、PCF实体获取组成员设备的V2X通信参数。
其中，PCF实体在接收到来自组控制设备的指示信息之后，PCF实体获取组成员设备的V2X通信参数。

需要说明的是，本申请实施例中的步骤603-605与前述图5中的步骤501-503类似，对于类似的内容此处不再赘述。
在一种实施方式中，组控制设备还向组成员设备发送组成员标识号，该组成员标识号可以在组成员设备请求PC5资源时使用。
在另一种实施方式中，在组控制设备向组成员设备发送组成员标识号之前，组控制设备获取该组成员标识号的方式可以包括：组控制设备可以为组成员设备分配该组成员标识号，或组控制设备接收来自PCF实体的该组成员标识号，或组控制设备接收来自接入网设备的该组成员标识号等。
在本申请实施例中，PCF实体接收到来自组控制设备的指示信息之后，确定组成员设备与组控制设备建立连接，即可获取组成员设备的V2X通信参数。然后PCF实体将该V2X通信参数发送给接入网设备，以使接入网设备可以在组控制设备的上下文中保存组成员设备的V2X通信参数。接入网设备可以根据保存在组控制设备的上下文中的组成员设备的V2X通信参数，为组成员设备分配PC5资源。使得组成员设备可以根据分配的PC5资源进行V2X业务的PC5接口通信。可以避免因接入网设备上未保存组成员设备的V2X通信参数，而导致无法为组成员设备分配PC5资源，使得组成员设备无法使用PC5资源进行V2X业务的数据传输。
其次，本申请中组成员设备的V2X通信参数还可以由组控制设备发送给接入网设备。请参阅图7，本申请实施例还提供了另一种数据处理方法，具体如下所述。
701、组成员设备向组控制设备发送V2X通信参数。
其中，组成员设备上保存了自身的V2X通信参数，因此，组成员设备可以将自身保存的V2X通信参数发送给组控制设备。
此外，在组成员设备向组控制设备发送V2X通信参数之前，组成员设备与组控制设备之间可以是已建立连接的状态，组成员设备与组控制设备之间也可以是未建立连接的状态。
702、组控制设备向接入网设备发送组成员设备的VX通信参数。
其中，组控制设备在接收到来自组成员设备的V2X通信参数时，组控制设备将该组成员设备的V2X通信参数发送至接入网设备。
703、接入网设备在组控制设备的上下文中保存组成员设备的V2X通信参数。
本申请实施例中的步骤703与前述步骤402类似，此处不再赘述。
在一种实施方式中，组控制设备也可以保存该组成员设备的V2X通信参数，以便后续对组成员设备进行授权检查。
在本申请实施例中，可以由组控制设备向接入网设备发送组成员设备的V2X通信参数，无需经过PCF实体，可以提高接入网设备得到组成员设备的V2X通信参数的效率。并且，接入网设备可以在组控制设备的上下文中保存组成员设备的V2X通信参数。接入网设备可以根据保存在组控制设备的上下文中的组成员设备的V2X通信参数，为组成员设备分配PC5资源。使得组成员设备可以根据分配的PC5资源进行V2X业务的PC5接口通信。可以避免因接入网设备上未保存组成员设备的V2X通信参数，而导致无法为组成员设备分配PC5资源，使得组成员设备无法使用PC5资源进行V2X业务的数据传输。
前述对本申请实施例中提供的数据处理的方法进行了说明，更进一步地，在接入网设备为组控制设备保存了组成员设备的V2X通信参数之后，接入网设备可以基于保存的组成员设备的V2X通信参数为组成员设备分配PC5资源。下面对本申请实施例提供的数据处理的方法进行更进一步地说明。
请参阅图8，本申请实施例提供的数据处理的方法的另一种实施例示意图，具体包括以下所述。
801、PCF实体获取组成员设备的V2X通信参数。
802、PCF实体向接入网设备发送组成员设备的V2X通信参数。
803、接入网设备在组控制设备的上下文中保存组成员设备的V2X通信参数。
需要说明的是，本申请实施例中的步骤801-803与前述步骤501-503类似，此处不再赘述。
804、组控制设备向接入网设备发送PC5资源请求消息。
其中，组控制设备向接入网设备发送PC5资源请求消息，该PC5资源请求消息用于请求接入网设备为至少一个组成员设备分配PC5资源。该至少一个组成员设备可以是一个或者多个组成员设备。该一个或多个组成员设备在组控制设备向接入网设备发送PC5资源请求消息之前，已与组控制设备建立连接，因此可以由组控制设备向接入网设备为该一个或多个组成员设备请求PC5资源。
具体地，该PC5资源可以用于组成员设备进行V2X业务。
具体地，该PC5资源请求消息中可以携带该一个或多个组成员设备的标识，以及PC5接口QoS流标识，或者，PC5接口通信服务质量标识(PC5 QoS identifier，PQI)，或者，一个或多个组成员设备的数据量等中的一项或者多项。PQI可以用于指示组成员设备的PC5通信的质量等级，数据量即组成员设备进行V2X业务所使用的数据量。
通常，组控制设备可以是主动向接入网设备发送PC5资源请求消息，为组成员设备请求PC5资源，也可以是在组控制设备接收到组成员设备的PC5资源请求消息之后，组控制设备向接入网设备发送PC5资源请求消息，为组成员设备请求PC5资源，具体可以根据实际应用场景进行调整，本申请对此不作限定。
具体地，该PC5资源请求消息中可以携带组成员设备的标识，以及，组成员设备的PC5接口QoS流标识、PC5接口通信PQI或数据量中的至少一种。使得接入网设备可以根据该成员设备的标识识别出组成员设备，并根据组成员设备的PC5接口QoS流标识、PC5接口通信PQI或数据量中的至少一种，以及保存的组成员设备的V2X通信参数，为组成员设备分配PC5资源。
805、接入网设备进行授权检查。
其中，在接入网设备接收到来自组控制设备的PC5资源请求消息之后，确定需要分配PC5资源的一个或多个组成员设备。然后对该一个或多个组成员设备进行授权检查。
具体地，接入网设备可以根据PC5资源请求消息中携带的组成员设备的标识，确定需要分配PC5资源的一个或多个组成员设备，并查找该一个或多个组成员设备中每个组成员设备的V2X通信参数。然后根据该每个组成员设备的V2X通信参数对每个组成员设备进行授权检查，确定每个组成员设备是否授权成功。
更具体的，对组成员设备的授权检查，即根据组成员设备的V2X通信参数，确定组成员设备是否可以使用V2X业务，或者，若组成员设备可以使用V2X业务，还可以结合PC5资源请求消息，进一步检查组成员设备进行V2X业务的服务质量等级等。若根据V2X通信参数确定组成成员设备可以使用V2X业务，或者，确定了组成员设备可以进行V2X业务的服务质量等级，则可以确定对组成员设备的授权检查成功。
应理解，授权检查可以是对组成员设备进行授权检查，组成员设备可以理解为组成员的载体，组成员即组通信中的成员。因此，也可以理解为对组成员进行授权检查。授权检查具体可以是检查组成员的V2X授权信息，例如，检查组成员是否被授权V2X业务，或者，是否可以使用PC5资源进行通信等。因此，在本申请实施例中，接入网设备可以对组成员设备进行授权检查，以确定是否可以为组成员设备分配PC5资源，避免盲目的分配PC5资源，提高资源利用率。
806、接入网设备为组成员设备分配PC5资源。
其中，在接入网设备对每个组成员设备进行授权检查之后，接入网设备根据授权检查的结果，为一个或多个组成员设备分配PC5资源。
具体地，若接入网设备确定其中一个组成员设备授权成功，则接入网设备可以为该组成员设备分配PC5资源，若该组成员设备授权不成功，则接入网设备不为该组成员设备分配PC5资源。该PC5资源可以是组成员设备在PC5接口上可以传输数据的时频资源。
在一种实施方式中，若其中一个组成员设备的V2X通信参数中包括组成员设备的PC5接口通信的QoS参数，则接入网设备可以根据该组成员设备的QoS参数以及PC5资源请求消息中携带的数据，为组成员设备分配PC5资源。
在另一种实施方式中，接入网设备在为组成员设备分配PC5资源时，除了参考组成员设备的QoS参数之外，接入网设备还可以结合PC5资源请求消息中携带的PC5接口QoS流标识、PQI或数据量等中的一种或多种，为组成员设备分配PC5资源。示例性地，可以按照PQI的值，结合V2X通信参数中的Qos参数，确定为组成员设备分配的PC5资源的等级，为每个组成员设备分配PC5资源；可以结合组成员设备的数据量，为组成员设备分配PC5资源。例如，如若组成员设备的PQI代表的QoS要求越高(通常时延越低可靠性越高，QoS要求越高)，或者数据量越大，则可以为该组成员设备分配更多的PC5资源。
807、接入网设备向组控制设备发送PC5资源的信息。
其中，在接入网设备为组成员设备分配PC5资源之后，接入网设备向组控制设备发送该PC5资源的信息。以使组控制设备在接收到该PC5资源的信息之后，通知各个组成员设备可以使用的PC5资源。
需要说明的是，本申请实施例中的步骤804-807为可选步骤。
通常，若组控制设备向接入网设备发送的PC5资源请求消息，请求接入网设备为多个组成员设备分配PC5资源。则接入网设备在确定各个组成员设备授权成功之后，为该多个组成员设备分配PC5资源。
在一种实施方式中，接入网设备可以直接通知组控制设备分配的PC5资源的信息，然后由组控制设备再对接入网分配的PC5资源进行详细划分，分别为每个组成员设备分配对应的PC5资源。接入网设备仅需通知组控制设备为多个组成员设备分配的所有PC5资源即可，无需为每个组成员设备单独划分PC5资源，或者无需为每个组成员设备进行实时的PC5资源调度，可以降低接入网设备的信令开销。
在另一种实施方式中，接入网设备也可以在分别为每个组成员设备分配PC5资源之后，接入网设备通知组控制设备为每个组成员设备分别分配的PC5资源，然后组控制设备通知每个组成员设备对应的PC5资源。
在一种实施方式中，若组控制设备向接入网设备发送的PC5资源请求，用于请求接入网设备为一个组成员设备分配PC5资源，则接入网设备在确定组成员设备授权成功之后，为该一个组成员设备分配PC5资源，并通知组控制设备。组控制设备可以直接将该PC5资源分配给该组成员设备，无需再进行详细划分。
在本申请实施例中，接入网在接收到组成员设备的V2X通信参数之后，在组控制设备的上下文中保存组成员设备的V2X通信参数。然后在接入网设备接收PC5资源请求消息之后，根据保存的V2X通信参数为组成员设备分配PC5资源。因此，接入网设备可以根据保存的V2X通信参数为组成员设备分配PC5资源，使得组成员设备可以使用接入网设备分配的PC5资源进行通信。可以避免接入网设备无法确定组成员设备是否可以授权，而导致接入网设备拒绝为组成员设备分配PC5资源，组成员设备无法进行PC5通信。
在本申请中，除了可以由接入网设备进行授权检查，若组控制设备上保存了组成员设 备的V2X通信参数，也可以由组控制设备进行授权检查。下面以一个组成员设备为例，对组控制设备进行授权检查的场景进行说明。请参阅图9，本申请实施例提供的数据处理的方法的另一种实施例示意图，具体包括以下所述。

902、PCF实体向接入网设备发送组成员设备的V2X通信参数。
903、接入网设备在组控制设备的上下文中保存组成员设备的V2X通信参数。
需要说明的是，本申请实施例中的步骤901-903与前述步骤501-503类似，此处不再赘述。

其中，组控制设备在接收到PCF实体发送的组成员设备的V2X通信参数之后，可以保存该组成员设备的V2X通信参数。
本申请实施例对步骤902与步骤903的执行顺序不作限定，可以先执行步骤902，也可以先执行步骤903，还可以同时执行步骤902与步骤903，具体可以根据实际应用场景进行调整。
905、组控制设备进行授权检查。
其中，组控制设备基于保存的组成员设备的V2X通信参数，对组成员设备进行授权检查。
具体的，组控制设备可以根据组成员设备的V2X通信参数，确定组成员设备是否可以使用V2X业务。
906、组控制设备向接入网设备发送PC5资源请求消息。
其中，若组控制设备确定组成员设备授权成功，则组控制设备向接入网设备发送PC5资源请求消息。若组控制设备确定组成员设备授权不成功，则组控制设备不向接入网设备发送PC5资源请求消息。
907、接入网设备为组成员设备分配PC5资源。
其中，接入网设备在接收到组控制设备发送的PC5资源请求消息之后，无需对组成员设备进行授权检查，可以直接基于PC5资源请求消息中所携带的信息为组成员设备分配PC5资源。
具体地，本申请实施例中的步骤907与前述步骤806类似，此处不再赘述。
908、接入网设备向组控制设备发送PC5资源的信息。
其中，本申请实施例中的步骤908与前述步骤807类似，此处不再赘述。
在本申请实施例中，PCF实体可以将组成员设备的VX通信参数发送至组控制设备，由组控制设备进行授权检查，接入网设备可以无需对组成员设备进行授权检查。在组控制设备对组成员设备进行授权检查确认授权成功之后，组控制设备才向接入网设备发送该组成员设备的PC5资源请求消息，接入网设备在接收到该PC5资源请求消息之后，无需进行授权检查，可以直接分配PC5资源，以减少接入网设备的工作流程，提高接入网设备分配PC5资源的效率。若组控制设备对组成员设备进行授权检查确认授权不成功，则组控制设备不为该组成员设备请求PC5资源，以进一步降低接入网设备的工作量，提高接入网设备的工 作效率。并且，接入网设备可以在组控制设备的上下文中保存组成员设备的V2X通信参数。接入网设备可以根据保存在组控制设备的上下文中的组成员设备的V2X通信参数，为组成员设备分配PC5资源。使得组成员设备可以根据分配的PC5资源进行V2X业务的PC5接口通信。可以避免因接入网设备上未保存组成员设备的V2X通信参数，而导致无法为组成员设备分配PC5资源，使得组成员设备无法使用PC5资源进行V2X业务的数据传输。
图8-图9对由PCF实体向接入网设备发送组成员设备的具体步骤进行了说明，下面对组控制设备向接入网设备发送组成员设备的具体步骤进行说明。请参阅图10，本申请实施例提供的数据处理的方法的另一种实施例示意图，具体包括以下所述。

在本申请实施例中，可以由组控制设备向接入网设备发送组成员设备的V2X通信参数，无需经过PCF实体，可以提高接入网设备得到组成员设备的V2X通信参数的效率。并且，接入网设备可以在组控制设备的上下文中保存组成员设备的V2X通信参数。在接入网设备接收到组控制设备为组成员申请请求PC5资源的PC5资源请求消息时，接入网设备可以根据保存在组控制设备的上下文中的组成员设备的V2X通信参数，为组成员设备分配PC5资源。使得组成员设备可以根据分配的PC5资源进行V2X业务的PC5接口通信。可以避免因接入网设备上未保存组成员设备的V2X通信参数，而导致无法为组成员设备分配PC5资源，使得组成员设备无法使用PC5资源进行V2X业务的数据传输。
前述对本申请实施例提供的数据处理的方法进行了详细说明，下面结合具体的应用场景，对本申请提供的数据处理的方法进行示例性说明。
场景一，请参阅图11，本申请实施例提供的数据处理的方法的另一种实施例示意图，可以包括：
1101、组成员设备与组控制设备建立连接。
具体地，组成员设备与组控制设备之间的连接可以参阅前述步骤601，此处不再赘述。
在一种实施方式中，在组成员设备与组控制设备之间建立组通信连接之后，该组通信可以对应一个组标识(Group ID)。
具体地，该组标识可以是在组控制设备与组成员设备建立了组通信连接之后，组控制设备即可直接分配该组标识；该组标识也可以是由PCF实体提前分配之后发送至组控制设备的，在组控制设备与组成员设备建立了组通信连接之后，即可确定该组通信对应的组标识。具体可以根据实际应用场景进行调整，本申请对此不作限定。
示例性地，在一种场景中，组控制设备与组成员设备都是UE，在UE1与UE2建立连接之后，可以将UE1作为组控制设备，UE2作为组成员设备，也可以将UE2作为组控制设备，UE1作为组成员设备，具体可以根据实际应用场景进行调整，本申请对此并不作限定。
1102、组控制设备向PCF实体发送指示信息。
其中，本申请实施例中的指示信息与前述步骤602中的指示信息类似。
组控制设备在与组成员设备建立连接之后，组控制设备可以向组控制设备的PCF实体发送指示信息。该指示信息可以用于指示组控制设备与组成员设备已建立连接。在另一种场景中，该指示信息还可以用于指示请求对组成员设备进行授权检查。
具体地，该指示信息可以包括组成员设备的标识。可选的，该指示信息还包括组控制设备的标识、组标识、组成员加入指示中的一个或多个。
示例性地，在本申请实施例中，组成员设备的标识可以是组成员设备的常用的身份标识号，例如，用户永久标识符(Subscriber Permanent Identifier，SUPI)、用户隐藏标识符(Subscription Concealed Identifier，SUCI)、临时标识符(Global Unique Temporary Identifier，GUTI)等等，也可以是由组控制设备或PCF实体分配的组成员标识号。其中，组成员设备的标识可以同时包括组成员设备的常用的身份标识号和组控制设备分配的组成员标识号。组成员标识号具体可以是随机分配的，也可以是按照预设规则分配的，该预设规则可以包括，组成员标识号的长度为预设值、或按照预设的顺序排列得到组成员标识号等等。
在一种实施方式中，若该组成员的标识包括组成员标识号，该组成员标识号可以由组控制设备直接分配，然后包括于该指示信息中。该组成员标识号可以在组成员设备请求PC5资源时使用。
在另一种实施方式中，若该组成员的标识为组成员标识号，且由PCF实体分配，则由PCF实体在组控制设备发送指示信息之前，发送至组控制设备。以使指示信息可以携带该组成员标识号。
在另一种实施方式中，若由PCF实体分配该组成员识别号，PCF实体除了可以将该组成员识别号发送至组控制设备和/或组成员设备，还可以将该组成员识别号发送至接入网设备。
在一种场景中，指示信息可以不携带组成员标识号，并且该组成员标识号由PCF实体在接收到指示信息之后，为组成员设备分配。
通常，在组控制设备与组成员设备建立了组通信连接之后，需要通知PCF实。具体地，组控制设备可以向PCF实体发送指示信息，以通知PCF实体组控制设备与组成员设备之间 已建立组通信连接。
此外，组控制设备通常无法直接将指示信息发送至PCF实体，可以由AMF实体转发。具体的，组控制设备可以向AMF实体发起上行非接入层(Non-access stratum，NAS)传输，通过NAS消息将该指示信息发送至AMF实体，然后由AMF实体通过N11消息，将指示信息发送至PCF实体。应理解，在本申请实施例中，在PCF实体向接入网设备或组控制设备等传输数据或消息时，都可以经由AMF实体进行转发，本申请实施例中不再一一赘述。
1103、PCF实体向UDR发送V2X通信参数请求消息。
其中，在PCF实体接收到来自组控制设备的指示信息之后，确定组成员设备与组控制设备已建立连接，PCF实体可以向UDR请求组成员设备的V2X通信参数。具体的，可以由PCF实体向UDR发送V2X通信参数请求消息，以请求组成员设备的V2X通信参数。
示例性地，该V2X通信参数请求消息中可以携带组成员设备的SUPI，以使UDR可以根据组成员的标识，识别出组成员设备，进而从存储的用户数据中提取组成员设备的V2X通信参数。其中，PCF实体可以根据指示信息中所包括的组成员的标识获取SUPI，可以包括：如果组成员的标识包括SUPI，则PCF实体可以直接识别指示信息中的SUPI；如果组成员的标识包括SUCI，则PCF实体根据SUCI获取SUPI，具体地，PCF实体可以依据该SUCI通过接入和移动性管理功能(AMF，access and mobnility management function)和/或认证服务器功能(AUSF，Authentication Server Function)获取SUPI；如果组成员的标识包括GUTI，则PCF实体可以根据GUTI获取SUPI，具体地，PCF实体可以通过AMF获取SUPI。
1104、UDR向PCF实体发送V2X通信参数。
其中，UDR在获取到组成员设备的V2X通信参数之后，向PCF实体发送V2X通信参数。
通常，UDR上保存了用户数据，V2X通信参数请求消息中可以携带组成员设备的标识，UDR可以根据组成员设备的标识从数据库或存储器中查找组成员设备的V2X通信参数，然后发送至PCF实体。
在一种实施方式中，PCF实体除了从UDR获取组成员设备的V2X通信参数，也可以从本地存储的数据中获取组成员设备的V2X通信参数，具体可以根据实际应用场景进行调整，此处并不作限定。
应理解，若PCF实体从本地存储的数据中获取组成员设备的V2X通信参数，则无须执行步骤1103和1104。
1105、PCF实体向接入网设备发送V2X通信参数。
其中，PCF实体在获取到V2X通信参数之后，向接入网设备发送该V2X通信参数。
在一种实施方式中，PCF实体在接收到V2X通信参数之后，PCF实体可以依据该V2X通信参数对组成员设备进行授权检查，若授权成功，则可以将组控制设备与组成员设备关联起来；当然，PCF实体也可以直接将组控制设备与组成员设备关联起来；或者，若组成员设备授权不成功，也可以将组控制设备与组成员设备关联起来，具体可以根据实际应用场景进行调整，本申请对此并不作限定。
在一种具体的实施方式中，组控制设备与组成员设备关联起来，可以包括：PCF实体将组成员设备的V2X通信参数保存至组控制设备相关的数据中；或者，PCF实体将组成员 设备的标识保存至组控制设备相关的数据中；或者，PCF实体将组控制设备的标识保存至组成员设备相关的数据中；或者，PCF实体在组控制设备相关的数据中添加指示数据，该指示数据用于指示组控制设备与组成员设备已建立连接；或者，PCF实体上建立有组通信数据，该组通信数据可以包括组控制设备与各个组成员设备的数据等，PCF实体将该组成员设备的V2X通信参数或标识保存至该组通信数据中，例如，若PCF实体上保存有组通信表格，其中包括了组控制设备的标识与组成员设备的标识。组控制设备与组成员设备之间具体的关联方式可以根据实际应用场景进行调整，本申请实施例仅仅是举例说明，对此并不作限定。
其中，组成员设备的V2X通信参数中可以包括组成员设备的V2X授权信息、和/或PC5Qos参数等，该V2X通信参数的详细介绍可以参阅前述步骤401。
在一种实施方式中，PCF实体在向接入网设备发送组成员设备的V2X通信参数时，还发送组成员设备的标识、组控制设备的标识、组标识等中的一个或多个，以使组控制设备根据以上的标识，确定如何保存组成员设备的V2X通信参数。V2X通信参数与组成员设备的标识、组控制设备的标识、组标识等中的一个或多个，可以是通过同一消息发送，也可以是分别独立发送。
在一种实施方式中，PCF实体除了可以将组成员设备的V2X通信参数发送至接入网设备，还可以将组成员设备的V2X通信参数发送给组控制设备，由组控制设备进行授权检查。此外，若PCF实体无需向组控制设备发送组成员设备的V2X通信参数，而PCF实体为组成员设备分配组成员识别号，则PCF实体可以单独将该组成员识别号发送至组控制设备，以使组控制设备将该组成员标识号发送至组成员设备。
在一种场景中，PCF实体可以调用Namf_Communication_N1N2MessageTransfer服务，通过N2消息将V2X通信参数发送至接入网设备，还可以通过N1消息将V2X通信参数发送至组控制设备，由控制设备进行授权检查。或者，若PCF实体无需将V2X通信参数发送至组控制设备，而PCF实体为组成员设备分配了组成员标识号，则可以直接通过N1消息将组成员标识号发送至组控制设备。
1106、接入网设备保存V2X通信参数。
本申请实施例中的步骤1106与前述步骤402类似，不再赘述。
在一种实施方式中，若接入网设备上保存了组成员设备的V2X通信参数，则接入网通知PCF实体或者组控制设备，以使PCF实体或组控制设备确定组控制设备对应的接入网设备上保存了组成员设备的V2X通信参数。
1107、组控制设备向组成员设备发送组成员标识号。
其中，组成员设备的组成员标识号可以由组控制设备分配，或者由PCF实体分配之后通知组控制设备。组控制设备在确定组成员设备的组成员标识号之后，可以将该组成员标识号发送给组成员设备。该组成员标识号可以在组成员设备请求PC5资源时使用。
在一种实施方式中，若该组成员的标识由PCF实体分配，则PCF实体还可以将该组成员标识号发送至组成员设备。
1108、组成员设备向组控制设备发送PC5资源请求消息。
在组成员设备需要PC5资源时，可以向组控制设备发送PC5资源请求消息。PC5资源请求用于请求PC5资源。例如，该PC5资源可以用于组成员设备进行V2X业务。
该PC5资源请求消息中可以携带组成员设备的组成员标识号，还可以携带组成员设备的PC5接口QoS流标识、PC5接口通信服务PQI或数据量中的至少一种。
1109、组控制设备向接入网设备发送PC5资源请求消息。
本申请实施例中的步骤1109与前述步骤804类似，不再赘述。
1110、接入网设备进行授权检查。
本申请实施例中的步骤1110与前述步骤805类似，不再赘述。
此外，需要说明的是，除了可以由接入网设备进行授权检查之外，若组控制设备上保存有组成员设备的V2X通信参数，也可以由组控制设备进行授权检查，若授权成功，则组控制设备直接向接入网设备发送PC5资源请求消息，接入网设备无需进行授权检查。具体的步骤可以参阅前述步骤905-908。
1111、接入网设备分配PC5资源。
其中，接入网设备在确定设备授权成功之后，或者在接收到来自组控制设备的PC5资源请求消息之后，即可为组成员设备分配PC5资源。
本申请实施例中步骤1111的具体步骤与前述步骤806类似，此处不再赘述。
1112、接入网设备向组控制设备发送PC5资源的信息。
本申请实施例中步骤1112与前述步骤807类似，此处不再赘述。
1113、组控制设备向组成员设备发送PC5资源的信息。
通常，若组控制设备为一个组成员设备请求了PC5资源，则接入网设备为该一个组成员设备分配PC5资源。
若组控制设备为多个组成员设备请求了PC5资源，则接入网设备可以为多个组成员分配PC5资源，并由组控制设备为每个组成员设备进行详细划分。也可以是，若组控制设备为多个组成员设备请求了PC5资源，接入网设备可以直接为多个组成员中的每个组成员设备分别分配PC5资源，然后由组控制设备通知每个组成员设备。
本申请实施例中的步骤1113与前述步骤807中的实施方式类似，此处不再赘述。
在本申请实施例中，接入网在接收到来自PCF实体的组成员设备的V2X通信参数之后，在组控制设备的上下文中保存组成员设备的V2X通信参数。然后在接入网设备接收PC5资源请求消息之后，根据保存的V2X通信参数为组成员设备分配PC5资源。因此，在由组控制设备为组成员设备请求PC5资源时，接入网设备可以根据保存的组成员设备的V2X通信参数，为组成员设备分配PC5资源，使得组成员设备可以使用接入网设备分配的PC5资源进行通信。
场景二，具体请参阅图12，本申请实施例提供的数据处理的方法的另一种实施例示意图，可以包括：

组成员设备向组控制设备对应的PCF实体发送指示信息，该指示信息可以用于指示组控制设备与组成员设备已建立连接。可选地，该指示信息还可以用于指示请求对组成员设备进行授权检查。
需要说明的是，本申请实施例中，组成员设备与组控制设备可以对应同一个PCF实体，因此，本申请实施例中，组成员向组控制设备对应的PCF实体发送指示信息，可以理解为组成员设备向组成员设备对应的PCF实体发送指示信息。当组成员设备与组控制设备对应不同的PCF实体时，则组成员设备通常仅能向组成员设备的PCF实体发送指示信息，后续的步骤1203-1205为组成员设备对应的PCF执行的步骤，步骤1206-1214为组控制设备对应的PCF实体执行的步骤。在本申请实施例中，仅对组成员设备与组控制设备对应同一个PCF实体的场景进行示例性说明。
具体地，该指示信息可以包括组控制设备的标识，可选的，还包括组成员设备的标识、组标识、组成员加入指示等中的一个或多个。其中，组成员加入指示可以用于指示组成员设备与组控制设备建立连接。可以理解为，在实际应用中，PCF实体可能无法确定组成员设备与组控制设备建立连接，因此，组成员设备可以向PCF实体发送指示信息，以通知PCF实体组成员设备与组控制设备已建立连接。
更具体的，组成员设备的标识可以与前述步骤1102中的组成员设备的标识类似，此处不再赘述。
1203、PCF实体向UDR发送V2X通信参数请求消息。

1205、PCF实体触发策略更新。
其中，因PCF实体接收到的是组成员设备发送的指示信息，因此，PCF实体需要触发组控制设备的策略更新，以将组成员设备的V2X通信参数发送至组控制设备对应的接入网设备。
需要说明的是，在本申请实施例中的流程，是在组成员设备与组控制设备对应同一个PCF实体的场景下所执行的。当组成员设备与组控制设备对应不同的PCF实体，则是由组成员设备的PCF实体接收到组成员设备发送的指示信息，然后从UDR处获取组成员设备的V2X通信参数，并将该V2X通信参数发送至组控制设备对应的PCF实体，并执行以下步骤1206-1214。当然，也可以是仅发送组成员设备的标识至组控制设备对应的PCF实体，由组控制设备对应的PCF实体从UDR获取组成员设备的V2X通信参数，并执行以下步骤1206-1214。
此外，若组成员设备与组控制设备对应同一个PCF实体，则PCF实体可以触发组控制设备的策略更新，也可以不触发组控制设备的策略更新。因此，本申请实施例的步骤1205为可选步骤，具体可以根据实际应用场景进行调整。
1206、PCF实体向接入网设备发送V2X通信参数。

在一种实施方式中，该响应消息中可以携带组成员设备加入组通信成功的指示，可以理解为PCF实体可以通知组成员设备PCF实体已确定组成员设备与组控制设备已建立连接。当然，PCF实体也可以不向组成员设备发送响应消息，本申请实施例中的步骤1208为可选步骤，具体可以根据实际应用场景进行调整。
在一种实施方式中，若PCF实体还为组成员设备分配组成员标识号，则该响应消息中还携带组成员设备的组成员标识号。组成员设备在请求PC5资源时，可以使用该组成员标识号。
1209、组成员设备向组控制设备发送PC5资源请求消息。
1210、组控制设备向接入网设备发送PC5资源请求消息。
1211、接入网设备进行授权检查。
1212、接入网设备分配PC5资源。
