示例性地,图2示出了5G网络系统架构的示意图。5G网络中包括UE以及(无线)接入网((Radio)Access Network,(R)AN)设备,还包括数据网络(Data Network,DN)以及以下多个核心网网元:
网络切片选择功能(Network Slice Selection Function,NSSF);
鉴权服务器功能(Authentication Server Function,AUSF);
统一数据管理(Unified Data Management,UDM);
接入和移动性管理功能(Access and Mobility Management Function,AMF);
会话管理功能(Session Management Function,SMF);
策略控制功能(Policy Control Function,PCF);
应用功能(Application Function,AF);
用户面功能(User Plane Function,UPF)。
其中,UE通过Uu接口与AN进行接入层连接,交互接入层消息及无线数据传输。UE通过N1接口与AMF进行非接入层(Non Access Stratum,NAS)连接,交互NAS消息。AMF是核心网中的移动性管理功能,SMF是核心网中的会话管理功能,AMF在对UE进行移动性管理之外,还负责会话管理相关消息在UE和SMF之间的转发。 PCF是核心网中的策略管理功能,负责制定对UE的移动性管理、会话管理、计费等相关的策略。UPF是核心网中的用户面功能,通过N6接口与外部数据网络进行数据传输,通过N3接口与AN进行数据传输。
具有ProSe能力的UE可以通过PC5接口广播数据单元,其他具有Prose能力的UE通过PC5接口接收广播。如图3所示,UE1通过PC5接口广播数据单元。
由于广播/组播模式的近距离通信只支持两个具有ProSe能力的UE之间直接通信,也就是两个UE需要在较近的范围内。如果监听UE距离广播/组播的UE较远,则无法监听到广播/组播信息。
本申请实施例中,可以考虑通过中继(Relay)UE转发广播/组播的方式。当两个具有ProSe能力的UE距离较远,无法直接通过PC5接口建立通信时,可以通过一个具有ProSe能力的Relay UE进行通信的中转。如图4,中继UE-R可以通过PC5接口与UE1进行直接通信,还可以通过PC5接口与UE2直接通信,则UE1和UE2可以通过UE-R进行业务交互。需要考虑中继UE如何确定收到的广播/或组播数据是可以进行中继的。
本申请实施例提供的方案,主要用于解决上述问题中的至少一个。

具体地,在第一终端设备向第二终端设备发送中继请求消息之前,方法还包括:第一终端设备以广播和/或组播形式发送中继发现请求消息,其中,中继发现请求消息包括第一中继服务码,中继发现请求消息用于请求配置有第一中继服务码的第二终端设备发送第一回应消息。
相应地,在第二终端设备接收第一终端设备发送的中继请求消息之前,方法还包括:第二终端设备接收第一终端设备以广播和/或组播形式发送的包含第一中继服务码的中继发现请求消息,并向第一终端设备发送第一回应消息。

可选地,中继请求消息还包括为第二终端设备分配的用于以广播和/或组播形式发送数据的源链路层标识、目标链路层标识以及QoS信息中的至少之一。在一些实施例中,第二终端设备可以使用为其分配的用于以广播和/或组播形式发送数据的源链路层标识、目标链路层标识以及QoS信息中的至少之一,对接收到的广播和/或组播数据进行中继。

利用上述至少一个实施例,接收到第一终端设备以广播和/或组播形式发送的数据的第二终端设备,可以基于第一识别信息确定接收到的数据是否可以进行中继,进一步 地,还可以确定中继广播和/或组播时使用的链路层标识以及QoS信息。下面提供几个具体的示例,以便于更清楚地了解本申请实施例的特点。为了方便描述和理解,在以下示例中,UE1表示第一终端设备,中继UE表示支持或者允许中继广播和/或组播数据的第二终端设备。
示例一
本示例中,中继UE上配置有与中继相关的信息(以下简称“中继信息”)。中继信息包括授权进行中继广播或者组播的信息,例如允许对属于特定业务的数据进行中继广播/组播的指示,或者允许对从特定层2标识监听获得的数据进行中继广播/组播的指示。中继信息还可以包括中继UE发送广播/组播数据的源层2标识、目标层2标识和QoS信息中的至少之一。
具体地,配置的中继信息可以参考以下举例的形式:
一种形式:业务标识,和/或,对该业务允许中继广播/组播的指示,和/或,对该业务中继广播/组播时使用的源L2标识,和/或,对该业务中继广播/组播时使用的目标L2标识,和/或,发送广播/组播数据的QoS信息。
另一种形式:接收数据的L2标识(即数据中携带的目标L2标识),和/或,对从该L2标识监听获得的数据允许中继广播/组播的指示,和/或,对从该L2标识监听获得的数据进行中继广播/组播时使用的源L2标识,和/或,对从该L2标识监听获得的数据进行中继广播/组播时使用的目标L2标识,和/或,发送广播/组播数据的QoS信息。
本示例中,如图7所示,数据传输方法包括:
步骤1:中继UE上配置有进行中继广播或者组播的相关信息,该信息也可以称为近距离策略配置。具体可以是预配置在中继UE上,或者是第一网络设备向中继UE配置下发的。例如,第一网络设备是位于核心网的PCF或者近距离管理网元,该信息由PCF或者近距离业务管理网元通过AMF发送到中继UE,具体可以使用UE配置更新、下行非接入层透传消息等发送到中继UE。又例如,第一网络设备也可以是近距离业务应用服务器,通过应用层消息发送到中继UE。
步骤2:UE1需要进行广播/组播时,分配使用源L2标识(以下称为“第一源L2标识”,并确定广播/组播所使用的目标L2标识(以下称为“第一目标L2标识”)。
步骤3:UE1使用第一源L2标识和第一目标L2标识,广播/组播数据单元。数据单元头部携带有第一源L2标识、第一目标L2标识,还可能携带业务标识。
步骤4:中继UE获得UE1广播/组播的数据单元,通过与步骤1中获得的近距离策略配置比较,确定是否需要对该数据单元进行中继。
例如,若步骤1中配置了允许中继广播/组播的业务标识,并且接收到的数据单元头部携带该业务标识,则对该数据单元进行中继广播/组播。
例如,若步骤1中配置了对于从第一目标L2标识收到的数据单元需要进行中继,则对该数据单元进行中继广播/组播。
中继UE确定中继广播/组播时使用的源L2标识、目标L2标识。一种情况下,中继UE可以直接使用收到的第一源L2标识、第一目标L2标识;另一种情况下,中继UE可以使用为中继UE分配的用于广播/组播数据的第二源L2标识、第二目标LW标识,例如中继UE自己分配的源L2标识、步骤1中配置的中继广播/组播时使用的目标L2标识;另一种情况下,中继UE可以使用自己生成的第二源L2标识和/或第二目标L2标识。
步骤5:中继UE使用步骤4中确定的源L2标识、目标L2标识广播/组播步骤3收到的数据单元,其中,广播/组播时使用的QoS信息为步骤1配置的QoS信息。
示例二
UE1、中继UE上配置有中继服务码,该中继服务码代表允许进行中继广播/组播。具体可以是预配置在UE上,或者也可以是第一网络设备下发的。例如第一网络设备是位于核心网的PCF或者近距离管理网元,该信息由PCF或者近距离业务管理网元通过AMF发送到UE,具体可以使用UE配置更新、下行非接入层透传消息等发送到UE。例如第一网络设备也可以是近距离业务应用服务器,通过应用层消息发送到UE。
UE1在广播/组播之前,如果期望有中继终端对自己的广播/组播数据进行中继,则先进行中继终端的发现。
一种方式是如图8所示,中继UE广播/组播宣告消息,在宣告消息中携带该中继服务码,UE1监听到宣告消息后获知中继UE支持中继广播/组播,从而可以选择该中继UE进行中继。
另一种方法是如图9所示,UE1先广播请求消息(例如前述中继发现请求消息),请求消息中包括该中继服务码,中继UE监听到请求消息后获知UE1需要请求中继服务,则发送回应消息给UE1,从而UE1可以选择该中继UE进行中继。
在选择了中继UE之后,UE1向中继UE发送中继请求消息,中继请求消息中包括需要进行中继广播/组播的数据的识别信息,还可以包括中继UE发送广播/组播数据的源层2标识、目标层2标识、QoS信息等一种或多种信息。
具体地,如图10所示,本示例中的数据传输方法包括:
步骤1:UE1向中继UE发送中继请求消息,中继请求消息中包括需要进行中继广播/组播的数据的识别信息。识别信息是可以用于匹配数据包的过滤器信息,例如IP三元组、IP五元组、以太网格式的过滤器信息、业务标识、源层2标识、目标层2标识等信息。该消息中还可以包括分配给中继UE的用于发送广播/组播数据的源层2标识、目标层2标识、QoS信息等一种或多种信息。
步骤2:UE1需要进行广播/组播时,分配使用第一源L2标识,并确定广播/组播所使用的第一目标L2标识。
需要说明的是,上述步骤1、2没有时序关系,例如可以先发送中继请求消息再分配广播/组播所使用的L2标识,也可以先分配广播/组播所使用的L2标识再发送中继请求消息。此外,步骤1、2中的源层2标识可以相同或不同,步骤1、2中的目标层2标识也可以相同或不同。
步骤3:UE1使用第一源L2标识和第一目标L2标识广播/组播数据单元。
步骤4:中继UE获得UE1广播/组播的数据单元,通过与步骤1中获得的需要进行中继广播/组播的数据识别信息匹配,对该数据单元进行中继。
中继UE确定中继广播/组播时使用的源L2标识、目标L2标识。一种情况下,中继UE直接使用收到的第一源L2标识、第一目标L2标识;另一种情况下,中继UE可以自己生成第二源L2标识、第二目标L2标识;另一种情况下,如果步骤1收到的中继请求消息中包含中继广播/组播时使用的源L2标识、目标L2标识,则使用收到的源L2标识、目标L2标识。
步骤5:中继UE使用中继广播/组播的源L2标识、目标L2标识,广播/组播步骤3收到的数据单元,广播/组播时使用的QoS信息为步骤1收到的QoS信息。
示例三
本示例与示例二的区别在于,中继UE收到中继请求消息后,会发送如图11中的步骤1b所示的中继回应消息。中继UE收到步骤1a的中继请求消息之后,根据其中携带的第一QoS信息确定第二QoS信息和第三QoS信息,将第二QoS信息在步骤1b中发送给UE1。步骤3中UE1广播/组播时使用的QoS信息为步骤1b中收到的QoS信息。步骤5中中继UE广播/组播时使用的QoS信息为第三QoS信息。
例如,步骤1a中发送的中继请求消息中携带的第一QoS信息为时延要求100ms(毫秒),中继UE基于时延要求100ms,确定第二QoS信息为时延要求30ms,第三QoS信息为时延要求70ms,则中继UE在步骤1b中发送给UE1的时延要求为30ms。UE1根据30ms的时延要求进行广播/组播,中继UE根据70ms的时延要求进行广播/组播。
又例如,步骤1a中的QoS信息为广播/组播范围100米,或者在100米范围内可以满足特定的QoS要求,中继UE确定的第二QoS信息为广播/组播范围30米,第三QoS信息为广播/组播范围70米,则中继UE在步骤1b中发送给UE1的广播/组播范围为30米。UE1根据30米的广播/组播范围进行广播/组播,或者保证30米的广播/组播范围内满足特定的QoS要求,中继UE根据70米的范围要求进行广播/组播。
