背景技术
在无线通信系统中,终端(User Equipment,UE)可以通过网络侧将业务数据传输至特定的多个其他终端,而网络侧通常是采用单播方式或者多播方式实现业务数据的传输。例如,在5G系统中,当网络侧采用单播方式向多个其他终端传输业务数据时,相应的网络功能可以复制多份相同的业务数据,并直接向多个其他终端中每一终端发送一份业务数据;而当网络侧采用多播方式向多个其他终端传输业务数据时,网络功能可以向该业务数据多个其他终端所处小区的基站发送业务数据,由基站发送至该多个其他终端。但是,目前网络侧采用单播方式或者多播方式向多个其他终端传输业务数据,通常是由协议约定或者预先配置,从而可能会导致无线通信系统的通信性能降低。

本实施例中,上述第一网络功能是网络侧中的网络功能实体设备,且其可以是任何能够基于上述第一多播业务信息指示上述模式选择结果的网络功能,具体地,上述第一网络功能可以是上述MBSF,或者,也可以是由上述MBSF和上述MB-SMF共同组成。
另外,上述第二网络功能也是网络侧中的网络功能实体设备,且在一终端需要向多个其他终端发送业务数据的情况下,其可以向上述第一网络功能调用包含上述第一多播业务信息的第一业务操作,具体地,可以是如下任一项:
在上述第一网络功能为MBSF的情况下,上述第二网络功能为MB-SMF;或者
在上述第一网络功能为由MBSF和MB-SMF共同组成的网络功能的情况下,上述第二网络功能为上述AMF和SMF中的至少一项,例如,第一网络功能为由MBSF和MB-SMF共同组成的网络功能且第二网络功能为AMF。

示例性地,在上述第一网络功能为MBSF且第二网络功能为MB-SMF的情况下,若MB-SMF被其他网络功能调用包含多播业务信息的业务操作,如MB-SMF被AMF调用包含多播业务信息(即第二多播业务信息)的多播会话操作(即上述第二业务操作)请求触发多播会话,则MB-SMF向MBSF调 用包含第一多播业务信息的第一业务操作;或者,在上述第一网络功能为由MBSF和MB-SMF共同组成的网络功能且第二网络功能为AMF的情况下,若AMF被SMF调用包含多播业务信息(即第二多播业务信息)的多播业务操作(即上述第二业务操作)请求触发多播业务,或者,AMF接收到基站节点(如RAN节点等)发送的包含多播业务信息(即第二多播业务信息)的消息(如N2Message请求消息),则AMF向MB-SMF调用包含第一多播业务信息的第一业务操作,等等。
需要说明的是,上述包含第二多播业务信息的消息,可以是由上述需要进行多播会话业务的终端发送,或者,也可以是基站节点在感知到终端对多播业务感兴趣(即需要进行多播会话业务)的情况下发送。
另外,上述包含第二多播业务信息的消息,可以是上述终端或者基站节点向第四网络功能发送的消息,该第四网络功能可以是上述第二网络功能,也可以是上述第二网络功能之外的网络侧的其他网络功能实体设备,例如,第四网络功能为网络侧中的SMF,等等。
例如,在上述第二网络功能为AMF的情况下,上述基站节点可以直接向AMF发送包括上述第二多播业务信息的消息;或者,也可以是终端向SMF发送包括上述第二多播业务信息的消息,且SMF向AMF调用包含上述第二多播业务信息的多播业务操作请求(即上述第二业务操作)触发多播业务,等等。

需要说明的是,上述第二多播业务信息可以是与上述第一多播业务信息相同的信息;或者,上述第二多播业务信息也可以是与第一多播业务信息不同的信息,在此并不进行限定。
其中,在上述第二多播业务信息与上述第一多播业务信息不同的情况下,上述第二多播业务信息可以是第二网络功能在第一多播业务信息中增加部分业务信息后的多播业务信息。
例如,在上述第一多播业务信息包含TMGI、终端的IP地址、会话链接标识、流标识和会话选项指示的情况下,上述第二多播业务信息除包含TMGI、终端的IP地址、会话链接标识、流标识和会话选项指示之外,还可以包含基站节点信息和终端的位置信息等中的至少一项,等等。
或者,在上述第二多播业务信息与上述第一多播业务信息不同的情况下,上述第二多播业务信息也可以是第二网络功能对第一多播业务信息中部分业务信息进行更改后的多播业务信息。
例如,在上述第一多播业务信息包含TMGI、终端的IP地址、会话链接标识、流标识和会话选项指示的情况下,第二网络功能可以将第一多播业务信息中的会话连接标识更改为终端的位置信息,即上述第二多播业务信息包含TMGI、终端的IP地址、会话链接标识、流标识和终端的位置信息,等等。
上述步骤202中,在第一网络功能被第二网络功能调用包含第一多播业务信息的第一业务操作的情况下,第一网络功能可以基于上述第一多播业务信息,确定模式选择结果,并向第二网络功能指示该模式选择结果,且第二网络功能被第一网络功能指示上述模式选择结果,即第二网络功能确定第一网络功能指示的模式选择结果。
本实施例中,上述模式选择结果可以是网络侧传输业务数据可以采用单播模式、多播模式和无模式中的任一种模式。需要说明的,在无模式情况下,网络侧不进行数据传输。
另外,上述第一网络基于第二多播业务信息确定模式选择结果,可以是基于第二多播业务信息中的任一信息确定模式选择结果,具体地,可以包括 如下至少一种实现方式:
方式一、基于TMGI或者IP多播地址确定模式选择结果,例如,协议约定业务类型1的业务数据传输采用多播模式,若第一多播业务信息包含用于指示业务类型1的TMGI,则上述模式选择结果为多播模式;或者,协议约定业务类型2的业务数据传输采用单播模式,若第一多播业务信息包含用于指示业务类型2的TMGI,则上述模式选择结果为单播模式,等等;
方式二、基于多播业务的用户数(即多个其他终端中终端的数量)确定模式选择结果,例如,在多播业务的用户数小于或者等于预设阈值的情况下,上述模式选择结果为单播模式;在多播业务的用户数大于预设阈值的情况下,上述模式选择结果为多单播模式,等等;
方式三、基于是否收到终端的IP地址或者是否收到终端的IP地址和端口号信息,确定模式选择结果,例如,若收到IP地址或者IP地址和端口号信息,则上述模式选择结果为多播模式;若未收到IP地址或者IP地址和端口号信息,则上述模式选择结果为单播模式;
方式四、基于是否收到会话连接标识确定模式选择结果,例如,若收到会话连接标识,则上述模式选择结果为多播模式;若未收到会话连接标识,则上述模式选择结果为单播模式;
方式五、基于是否收到QFI确定模式选择结果,例如,若收到QFI,则上述模式选择结果为多播模式;若未收到QFI,则上述模式选择结果为单播模式;
方式六、基于是否收到会话选项指示,或者基于会话选项指示所指示的信息确定模式选择结果,例如,若收到会话选项指示或者会话选项指示指示信息1,则上述模式选择结果为多播模式;若未收到会话选项指示或者会话选项指示指示信息2,则上述模式选择结果为单播模式;
方式七、基于是否收到基站节点信息,或者基于基站节点信息指示的基站节点是否支持多播,确定模式选择结果,例如,若收到基站节点信息或者基站节点支持多播,则上述模式选择结果为多播模式;若未收到基站节点信息或者基站节点不支持多播,则上述模式选择结果为单播模式;
等等。
本实施例中,上述第一网络功能可以是通过任何方式为第二网络功能指示模式选择结果,具体地,可以包括向所述第二网络功能返回模式信息,所述模式信息用于指示所述模式选择结果(即显式指示);或者,不返回模式信息,用于指示所述模式选择结果(即隐式指示),等等。
例如,在第一网络功能基于第一多播业务信息确定多播模式的情况下,第一网络功能向第二网络功能调用包含模式信息的第三业务操作,该模式信息用于指示多播模式;或者,第一网络功能向第二网络功能调用不包含模式信息的第三业务操作(该第三业务操作还可以包含TMGI或IP多播地址,),此时,第二网络功能根据第三业务操作中不包含模式信息,确定第一网络功能选择的传输模式为多播模式,等等。
当然,上述第二网络功能被第一网络功能指示模式选择结果,即第二网络功能确定第一网络功能指示的模式选择结果,可以是根据第二网络功能接收到的第一网络功能返回的模式信息,获取模式信息指示的模式选择结果;或者,也可以是根据第一网络功能是否返回模式信息,确定模式选择结果,例如,若返回模式信息,则确定模式选择结果为单播模式;若未返回模式信息,则确定模式选择结果为多播模式,等等。
另外,在上述第二网络功能被第一网络功能指示上述模式选择结果之后,第二网络功能还可以向第三网络功能指示模式选择结果,以实现网络侧采用模式选择结果对应的数据传输模式向多个其他终端传输终端的业务数据。
需要说明的是,上述第三网络功能为上述网络侧中除第二网络功能之外的网络功能实体设备,具体地,上述第三网络功能可以为AMF或者SMF。
例如,在上述第二网络功能为MB-SMF的情况下,上述第三网络功能可以为AMF,且MB-SMF可以向AMF调用包含模式信息的第三业务操作(如多播会话响应操作),当然,该第三业务操作还可以包含MB-UPF的地址信息,则MB-SMF根据模式信息指示的模式控制MB-UPF向多个其他终端传输业务数据,或者,也可以是AMF直接根据模式信息指示的模式控制MB-UPF向多个其他终端传输业务数据,具体地,若上述模式信息指示多播模式,则MB-SMF或者AMF建立MB-UPF与基站节点之间的连接,并转发其接收到的终端的多播业务数据;若上述模式信息指示单播模式,则MB-SMF或者 AMF命令MB-UPF增加转发操作,将接收到的多播业务数据转发给接收到的终端的IP地址或终端的IP地址和端口号对应的其他终端,且MB-SMF或者AMF记录会话连接或流与多播业务的关联关系;若模式信息指示无模式,则MB-SMF或者AMF不建立MB-UPF与基站节点间的连接,也不命令MB-UPF增加转发操作。
为便于对本实施例提供的通信方法的理解,在此提供上述通信方法在实际应用中的示例进行说明,具体如下:
示例一、如图3所示,上述通信方法的实现过程包括:

其中,MBSF判断多播业务的模式可以依据多播业务的加入用户数,或是否收到终端的IP地址,或是否收到会话连接标识,或是否收到QFI,或是否收到会话选项指示,或RAN节点是否支持多播,等等;
另外,MBSF通过多播授权响应返回多播授权操作结果和模式选择结果指示,还可以包含多播业务信息,该多播业务信息可以包含TMGI或IP multiicast address,还可以携带MB-UPF的地址信息;
上述模式选择结果可以通过携带模式信息指示,比如多播模式、单播模式或无模式(即不提供数据传输);或者,也可以通过不携带模式信息指示,指示多播模式、单播模式和无模式中的一种。
步骤306、MB-SMF(在此为上述第三网络功能)通过多播会话响应返回多播会话操作结果,可以是返回MBSF指示的模式信息,即,如果MBSF返回模式信息给MB-SMF,则MB-SMF可以返回模式信息给AMF,如果MBSF不返回模式信息给MB-SMF,则MB-SMF不返回模式信息给AMF。
步骤307、AMF通过多播业务响应返回多播业务操作结果,可以是返回 MB-SMF指示的模式信息,即,如果MB-SMF返回模式信息给AMF,则AMF可以返回模式信息给SMF,如果MB-SMF不返回模式信息给AMF,则AMF不返回模式信息给SMF,SMF依据模式指示结果操作,比如多播模式或无模式时释放不需要的资源,单播模式时建立转发资源。
步骤308、如果模式选择结果指示为多播模式(显式或隐式指示多播模式),则MB-SMF建立MB-UPF与RAN节点间的连接,用于转发MB-UPF接收到的多播业务数据;
如果模式选择结果指示为单播模式(显式或隐式指示单播模式),则MB-SMF命令MB-UPF增加转发操作,将接收到的多播业务数据增加转发给接收到的终端的IP地址,或终端的IP地址和端口号,MB-SMF记录会话连接或流与多播业务的关联关系;
如果模式选择结果为无模式(显式或隐式指示无模式),则MB-SMF不建立MB-UPF与RAN节点间的连接,也不命令MB-UPF增加转发操作。

步骤406、MBSF判断多播业务的模式(即确定模式选择结果);
其中,MBSF判断多播业务的模式可以依据多播业务的加入用户数,或是否收到终端的IP地址,或是否收到会话连接标识,或是否收到QFI,或是否收到会话选项指示,或RAN节点是否支持多播,等等;
另外,MBSF通过多播授权响应返回多播授权操作结果和模式选择结果指示,还可以包含多播业务信息,该多播业务信息可以包含TMGI或IP multiicast address,还可以携带MB-UPF的地址信息;
上述模式选择结果可以通过携带模式信息指示,比如多播模式、单播模式或无模式(即不提供数据传输);或者,也可以通过不携带模式信息指示,指示多播模式、单播模式和无模式中的一种。
步骤407、MB-SMF(在此为上述第三网络功能)通过多播会话响应返回多播会话操作结果,可以是返回MBSF指示的模式信息,即,如果MBSF返回模式信息给MB-SMF,则MB-SMF可以返回模式信息给AMF,如果MBSF不返回模式信息给MB-SMF,则MB-SMF不返回模式信息给AMF。
步骤408、AMF通过多播业务响应返回多播业务操作结果,可以是返回MB-SMF指示的模式信息,即,如果MB-SMF返回模式信息给AMF,则AMF 可以返回模式信息给SMF,如果MB-SMF不返回模式信息给AMF,则AMF不返回模式信息给SMF,SMF依据模式指示结果操作,比如多播模式或无模式时释放不需要的资源,单播模式时建立转发资源。
步骤409、如果模式选择结果指示为多播模式(显式或隐式指示多播模式),则MB-SMF建立MB-UPF与RAN节点间的连接,用于转发MB-UPF接收到的多播业务数据;

如果模式选择结果指示为单播模式(显式或隐式指示单播模式),则MB-SMF命令MB-UPF增加转发操作,将接收到的多播业务数据增加转发给接收到的终端的IP地址,或终端的IP地址和端口号,MB-SMF记录会话连接或流与多播业务的关联关系;
如果模式选择结果为无模式(显式或隐式指示无模式),则MB-SMF不建立MB-UPF与RAN节点间的连接,也不命令MB-UPF增加转发操作。
