请参考图1，其示出了本公开实施例提供的一种无线通信***的结构示意图。如图1所示，无线通信***是基于移动通信技术的通信***，该无线通信***可以包括：若干个用户设备110以及若干个基站120。
其中，用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备110可以是物联网用户设备，如传感器设备、移动电话和具有物联网用户设备的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、 用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者，用户设备110也可以是无人飞行器的设备。或者，用户设备110也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线用户设备。或者，用户设备110也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。

其中，基站120可以是4G***中采用的演进型基站(eNB)。或者，基站120也可以是5G***中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站120的具体实现方式不加以限定。
基站120和用户设备110之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于***移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。

为了便于本领域内技术人员理解，本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然，本领域内技术人员可以理解，本公开实施例提供的多个实施例，可以被单独执行，也可以与本公开实施例中其他实施例的方法结合后一起被执行，还可以单独或结合后与其他相关技术中的一些方法一起被执行；本公开实施例并不对此作出限定。
为了更好地理解本公开实施例公开的技术方案，以下对无线网络通信的应用场景进行说明：
在一些实施例中，针对单个终端制定相关的移动性管理和会话管理等流程。网络在管理终端和给终端分配资源时都是针对单个终端。在一些应用场景中，由于单个终端的能力有限，无法完成复杂的需求和任务。需要多个终端相互配合工作才能完成。例如，在工业场景中，生产线上的机器人、监控器和控制器等终端需要相互配合完成生产任务。再例如，智慧舞台上的摄像机、麦克风、后台处理服务器、控制台和音响设备等终端需要共同配合工作才能呈现完美的舞台效果。
在一个实施例中，不同的终端执行同一个任务，分别建立单独的PDU会话来传输数据到数据网络的应用服务器(AS，Application Server)。此时，网络侧无法感知执行相同任务的多个终端，导致无法在网络侧进行优化和增强。例如，由于基站无法同时调度多个终端的数据，导致多个终端业务到达应用服务器的时间差比较大，业务体验比较差。再例如，某个智能中心，需要同时输入多路高清的图像源才能提供高清业务，如果多路中的某一路图像不够清晰，则提供清晰度最差的图像画质，这个时候网络并不能降低其他路的图像清晰度以节省网络资源，实现多路协调。因此，当多个终端执行相同的任务且多个终端传输的业务之间存在强相关性，可以通过建立多个终端共享的会话，以实现简化建立多个终端的会话管理流程、优化网络资源的分配并提升多个终端业务的整体性能。
如图2所示，本实施例中提供一种多终端共享PDU会话的方法，其中，该方法由终端执行，该方法，包括：
步骤21、向基站发送请求建立共享分组数据单元PDU会话的请求消息；
其中，所述共享PDU会话，用于供多个终端与数据网络DN进行通信。
这里，该终端可以是但不限于是手机、可穿戴设备、车载终端、路侧单元(RSU，Road Side Unit)、智能家居终端、工业用传感设备或医疗设备等。这里，共享PDU会话，可以是用于供多个执行指定任务的终端与数据网络DN进行通信。多个执行指定任务的终端可以是为了完成某个指定任务需要相互配合的多个终端。例如，生产线需要完成产品的生产任务，生产线上的机器人、监控器和控制器等终端需要相互配合完成生产任务，则多个执行指定任务的终端可以包括机器人、监控器和控制器等终端。再例如，舞台需要实现良好声光效果的任务，舞台上的摄像机、麦克风、后台处理服务器、控制台和音响设备等终端需要共同配合才能实现好的声光效果，则多个执行指定任务的终端可以包括摄像机、麦克风、后台处理服务器、控制台和音响设备等终端。这里，与终端进行通信的DN包括至少一个应用服务器AS。这里，需要说明的是，终端可以是与所述终端对应的AS进行通信，也可以是多个终端与同一个AS进行通信。
这里，基站可以为各种类型的基站，例如，第三代移动通信(3G)网络的基站、***移动通信(4G)网络的基站、第五代移动通信(5G)网络的基站或其它演进型基站。
本公开实施例中涉及的核心网设备可以包括接入和移动性管理功能(AMF，Access and Mobility Management Function)实体、会话管理功能(SMF，Session Management Function)实体和用户面功能(UPF，User Plane Function)实体中的一种或者多种。
这里，共享PDU会话，可以是供终端组内多个执行指定任务的终端与DN进行通信的会话。
在一个实施例中，可以是向基站发送请求建立分享PDU会话的请求消息，其中，所述共享PDU会话可以是用于供终端组内多个执行指定任务的终端与DN进行通信。这里，终端组内包含的终端可以是与指定任务关联的终端。例如，生产线需要完成产品的生产任务，生产线上的机器人、监控器和控制器等终端需要相互配合完成生产任务，则终端组内包含的终端可以包括机器人、监控器和控制器等终端。终端组内包含的终端也可以是与指定任务的某个业务关联的终端。例如，会议室内需要举行会议，会议涉及的终端包括多媒体业务的终端(包括音频终端和视频终端)和考勤业务的终端，则终端组内包含的终端可以是进行多媒体业务的音频终端和视频终端。这里，需要说明的是，分享PDU会话在该实施例中也可以被描述为组PDU会话或者组会话。
在一个实施例中，响应于多个终端需要执行指定任务，向基站发送请求建立共享分组数据单元PDU会话的请求消息。基站在接收到该请求消息后会将该请求消息发送给核心网设备；核心网设备在接收到该请求消息后会建立共享PDU会话；核心网设备在建立共享PDU会话后会通过基站向终端发送响应消息。在终端接收到该响应消息后，多个终端会基于该建立的共享PDU会话与DN进行通信。
在另一个实施例中，终端会接收核心网通过基站发送指示建立共享PDU会话的指示信息；终端在接收到该指示信息后会向基站发送请求建立共享分组数据单元PDU会话的请求消息。基站在接收到该请求消息后会将该请求消息发送给核心网设备；核心网设备在接收到该请求消息后会建立共享PDU会话；核心网设备在建立共享PDU会话后会通过基站向终端发送响应消息。在终端接收到该响应消息后，多个终端会基于该建立的共享PDU会话与DN进行通信。
在一个实施例中，多个终端基于共享PDU会话与DN进行通信可以是多个终端基于共享PDU会话的相同资源与DN进行通信。例如，共享PDU会话的而资源为A资源，则多个终端中的第一终端和第二终端就可以利用A资源在终端与DN之间进行数据传输。需要说明的是，资源可以是时域资源和/或频域资源，也可以是存储资源，还可以是算力资源。
在一个实施例中，基于共享PDU会话与DN进行通信的多个终端在进行数据传输时，可以进行终端之间的资源协调。例如，该多个终端中的第一终端利用B资源进行第一终端与DN之间的数据传输，该多个终端中的第二终端利用C资源进行第二终端与DN之间的数传输，当B资源不足时，可以将C资源中的部分资源分配给第一终端使用。
在一个实施例中，基于共享PDU会话与DN进行通信的多个终端在进行数据传输时，可以进行跨终端的业务流调度。例如，第一终端与DN进行通信的业务流为业务流A，第二终端与DN之间进行通信的业务流为业务流B，当第一终端与DN之间进行通信的通信质量大于质量阈值时，可以将业务流B中的部分分配给第一终端。
在一个实施例中，基于共享PDU会话与DN进行通信的多个终端在进行数据传输时，可以进行跨终端的业务流切换。例如，第一终端与DN进行通信的业务流为业务流A，第二终端与DN之间进行通信的业务流为业务流B，其中，A大于B；当第一终端与DN之间进行通信的通信质量小于质量阈值且第一终端与DN之间进行通信的通信质量大于质量阈值时，可以将业务流B分配给第一终端并将业务流A分配给第二终端。
在本公开实施例中，向基站发送请求建立共享分组数据单元PDU会话的请求消息；其中，共享PDU会话，用于供多个终端与数据网络DN进行通信。这里，终端可以请求建立用于供多个终端与DN进行通信的共享PDU会话，相较于终端只能请求建立用于供单个终端与DN进行通信的PDU会话且每个终端都需要建立一个PDU会话的方式，共享PDU会话能够供多个终端与DN进行通信，如此，能够减少信令交互，提升网络资源利用率，并给用户带来好的体验。
需要说明的是，本领域内技术人员可以理解，本公开实施例提供的方法，可以被单独执行，也可以与本公开实施例中一些方法或相关技术中的一些方法一起被执行。

在一个实施例中，该响应消息，携带指示共享PDU会话的会话标识。
在一个实施例中，请求消息，携带指示所述共享PDU会话的会话标识。可以是终端向基站发送携带会话标识的请求消息。基站在接收到该请求消息后会将该请求消息发送给核心网设备；核心网设备在接收到该请求消息后会建立共享PDU会话；核心网设备在建立共享PDU会话后会通过基站向终端发送携带会话标识的响应消息。在终端接收到该携带该会话标识的响应消息后，多个终端会基于该建立的共享PDU会话与DN进行通信。
