图2是5G网络中利用Prose功能进行中继传输的系统200框图。如图2所示,具有Prose能力的UE可以通过PC5接口与具有Prose能力的另外一个UE直接通信。当一个UE既可以通过5G网络连接外部数据网络,还具有Prose能力时,这个UE可以充当Relay UE,另外一个具有Prose能力的Remote UE可以通过PC5接口与Relay UE建立直接连接,并通过Relay UE与5G网络建立的PDU会话与外部网络交互。
相关技术中,Relay UE与核心网之间建立的PDU会话可以是IP类型、以太网类型、非结构化类型,分别用于传输具有IP类型包头、以太网类型包头、非结构化包头的数据。Remote UE与Relay UE之间发送的数据也可以是IP类型、以太网类型、非结构化类型。如果Remote UE发送给Relay UE的需要进行中继的数据与Relay UE与核心网之间建立的PDU会话类型不一致,则会出现Relay UE无法正确传输从Remote UE收到的数据的情况。例如,Relay UE与核心网之间建立的PDU会话是以太网类型,但是Relay UE从Remote UE收到的需要进行中继的数据是IP类型或者非结构化类型;或者Relay UE与核心网之间建立的PDU会话是非结构化类型,但是Relay UE从Remote UE收到的需要进行中继的数据是IP类型或者以太网类型;这两种情况下Relay UE都无法进行数据的中继发送。
鉴于上述情况,本申请提出一种数据传输方法,本申请提出的数据传输方式不限于在5G网络中使用,还可以应用于其他通信网络。
图3是根据本申请实施例的一种数据传输方法300的示意性流程图,该方法可选 地可以应用于图1或图2所示的系统,但并不仅限于此。该方法包括以下内容的至少部分内容。
S310:第一终端设备从网络设备接收第一信息和该第一信息对应的中继数据类型信息,该中继数据类型信息指示中继数据的类型;
S320:第一终端设备向第二终端设备发送该类型的中继数据。
可选地,上述第一终端设备为包括作为Remote UE的终端设备,上述第二终端设备包括作为Relay UE的终端设备。
在一些实施方式中,上述中继数据的类型包括:国际互连协议(IP,Internet Protocol)类型、以太网类型或非结构化类型。
在一些实施方式中,上述第一信息包括以下至少之一:
中继业务代码(RSC,Relay Service Code);
应用信息;
域名信息;
应用请求的连接能力描述信息。
其中,上述应用信息可以为应用标识。
其中,上述应用请求的连接能力描述信息可以为短信连接、互联网连接等。
可选地,上述步骤S310中,第一终端设备从网络设备接收第一信息和该第一信息对应的中继数据类型信息,包括:
第一终端设备从网络设备接收近距离通信配置,该近距离通信配置中包括第一信息和该第一信息对应的中继数据类型信息。
在一些实施方式中,第一终端设备向第二终端设备发送该类型的中继数据之前,上述过程还可以包括:第一终端设备建立与第二终端设备之间的近距离通信连接,该近距离通信连接对应上述第一信息。
其中,上述近距离通信连接可以为PC5连接。
第一终端设备可以通过第一终端设备与第二终端设备之间的对应第一信息的近距离通信连接,发送该第一信息对应的类型的中继数据。
在一些实施方式中,上述网络设备包括PCF。
在以下实施例中,以应用于5G网络,网络设备为PCF、第一终端设备为Remote UE,第二终端设备为Relay UE为例进行介绍。
实施例一:
图4是本申请实施例一的实现流程图,包括:
PCF向作为Relay UE的终端发送近距离通信配置,该近距离通信配置中包括第一信息以及第一信息所对应的PDU会话类型(以下简称第二类型)。PDU会话类型包括IP类型、以太网类型、非结构化类型。第一信息包括如下之一或者组合:
-中继业务代码(RSC)
-应用信息,例如应用标识
-域名信息
-应用请求的连接能力描述,例如短信连接,互联网连接
并且,PCF向作为Remote UE的终端发送近距离通信配置,其中包括第一信息以及第一信息所对应的中继数据类型(以下简称第一类型)。中继数据类型包括IP类型、以太网类型、非结构化类型。第一信息包括如下之一或者组合:
-中继业务代码(RSC)
-应用信息,例如应用标识
-域名信息
-应用请求的连接能力描述,例如短信连接,互联网连接
在配置中继数据的类型和PDU会话的类型时,PCF需要保证上述第第二类型的PDU会话能够传输上述第一类型的中继数据。
例如,当PCF配置给Relay UE的第一信息所对应的PDU会话类型为以太网类型时,配置给Remote UE的该第一信息所对应的中继数据类型也是以太网类型;
又如,当PCF配置给Relay UE的第一信息所对应的PDU会话类型为非结构化类型时,配置给Remote UE的该第一信息所对应的中继数据类型也是非结构化类型;
又如,当PCF配置给Relay UE的第一信息所对应的PDU会话类型为IP类型时,配置给Remote UE的该第一信息所对应的中继数据类型可以是IP类型或者以太网类型或者非结构化类型。
当Remote UE需要通过Relay UE进行中继业务时,Remote UE与Relay UE之间建立对应于该第一信息的PC5连接。以该第一信息为RSC为例,建立PC5连接的过程可以包括:Relay UE广播自身支持的多个RSC。Remote UE从Relay UE支持的多个RSC中选择一个,向Relay UE发送近距离连接建立请求,请求建立对应该RSC的PC5连接。Relay UE向Remote UE返回近距离连接建立响应,建立Relay UE与Remote UE之间对应与该RSC的PC5连接。上述内容仅为对建立PC5连接过程的举例,本申请实施例还可以采用其他的方式建立Remote UE与Relay UE之间的近距离通信连接,该近距离通信连接可以为PC5连接或其他形式的通信连接。
接着,Remote UE根据从PCF获得的近距离通信配置确定中继数据的类型,并将该类型的中继数据通过Relay UE与Remote UE之间的PC5连接发送到Relay UE。Relay UE根据从PCF获得的近距离通信配置确定Relay UE与核心网之间对应于该第一信息的PDU会话的类型,建立该类型的PDU会话,通过该PDU会话将从Remote UE收到的数据进行中继。由于PCF配置的上述第二类型的PDU会话能够传输上述第一类型的中继数据,因此Relay UE从Remote UE收到的数据能够被正确传输。
实施例二:
图5是本申请实施例二的实现流程图,如图5所示,PCF向作为Relay UE的终端发送UE路由选择策略,该UE路由选择策略中包括第一信息以及第一信息所对应的PDU会话类型。
本实施例中的其他内容与实施例一的相应内容相同,在此不再赘述。
可见,上述两个实施例中,通过PCF对Remote UE和Relay UE进行相应的配置,避免Remote UE发送给Relay UE的需要进行中继的数据类型与Relay UE与核心网之间建立的PDU会话类型不一致的情况,从而解决了Relay UE无法正确传输从Remote UE收到的数据的问题。
需要说明的是,上述示例仅为举例,本申请提出的方法不限于在5G网络中使用,并且上述Relay UE与核心网之间建立的会话不限于PDU会话。
本公开还提出一种建立会话的方法,图6是根据本申请实施例的一种建立会话的方法600的示意性流程图,该方法可选地可以应用于图1或图2所示的系统,但并不仅限于此。该方法包括以下内容的至少部分内容:
S610:第二终端设备从网络设备接收第一信息和该第一信息对应的第一会话类型信息,该第一会话类型信息指示第一会话的类型;
S620:第二终端设备建立该类型的第一会话。
可选地,上述第一会话包括PDU会话。

RSC;
应用信息;
域名信息;
