下面将结合附图，对本申请实施例进行详细描述。
本申请实施例提供的方法可以由终端设备执行，也可以由终端设备的部件(例如处理器、芯片、或芯片系统等)执行。本申请实施例提供的方法可以由网络设备执行，也可以由网络设备的部件(例如处理器、芯片、或芯片系统等)执行。执行本申请实施例的方法的主体也可以称为通信装置，通信装置可以是终端设备，终端设备的部件(例如处理器、芯片、或芯片系统等)，或者通信装置可以是网络设备，网络设备的部件(例如处理器、芯片、或芯片系统等)。为作区分，可以用第一通信装置和第二通信装置来分别表示终端设备和网络设备。其中，第一通信装置对应于终端设备，第二通信装置对应于网络设备。
以下介绍一下DEP协议的概念。
DEP协议，支持终端设备和算力上的应用之间的信息交互。信息交互可以包括信令交互和数据交互。数据可以是指用户面的数据，信令可以是指控制面的信令。终端设备和算力上的应用能够通过DEP协议进行通信，终端设备和算力都支持DEP协议。在一种可能的实现方式中，终端设备通过网络设备与算力上的应用进行通信，终端设备、网络设备和算力都支持DEP协议。基于DEP协议的数据可以承载于DEP会话。终端设备与网络设备之间可以建立无线承载。无线承载可以是数据无线承载(data radio bearer，DRB)，也可以是信令无线承载(signaling radio bearer，SRB)。DRB用于承载数据，SRB用于承载信令。本申请实施例的无线承载也可以是任何形式的无线承载。
在一种可能的实现方式中，DEP层在协议栈中的位置可以在无线网络协议层的第三层 之下，例如无线网络协议层的第三层可以是无线资源控制(radio resource control，RRC)层。DEP层还可以在媒体接入控制(media access control，MAC)层或物理(physical，PHY)层之上。图2示出了终端设备、网络设备和算力中DEP在协议栈的位置示例。DEP会话构建在DEP层上，或者DEP会话位于DEP层。
本申请实施例描述的各类DEP消息、DEP数据或DEP信令都可以基于DEP协议栈完成。以任意一种DEP消息为例，DEP消息可使用基于DEP协议栈的RRC/NAS信令传输。如图2所示，通过RRC层或NAS层向DEP层传输该DEP消息。NAS层可以在RRC层之上。RRC/NAS消息作为DEP的有效负载(payload data)。如果DEP消息是基于RRC/NAS实现，则终端设备发送给网络设备时，可以选择SRB来传输DEP认证请求消息，与无线其他RRC/NAS信令消息类似，而不是使用DRB或其他形式的无线承载来传输DEP认证请求消息。
或者，DEP消息也可以通过DEP定义的DEP专属信令来传输。例如，终端设备通过与网络设备对等的DEP协议层传输DEP消息，网络设备通过与算力对应的DEP协议层传输DEP消息。下面对DEP协议可能包括的字段或者DEP格式进行举例说明。
表1
Figure PCTCN2021108233-appb-000001
如表1所示，DEP协议可能包括的以下一种或多种字段：
类型(type)字段：用于指示DEP类型的字段，指示该DEP数据包的类型。根据规定type字段的取值不同，例如type字段可以是DEP注册信令、会话请求信令或者用户数据等。type字段的取值可以是1、2、3、…。例如，type字段的取值为1表示DEP类型为DEP注册信令，type字段的取值为2表示DEP类型为会话请求信令，type字段的取值为3表示DEP类型为用户数据。当然这里的type字段的取值仅仅是举例，实际应用中可以用其它取值来表示不同的type。
会话标识(Session ID)字段：用于指示DEP会话标识的字段，指示该DEP数据包所在的会话，是DEP会话的唯一标识，不同的DEP会话拥有不同的session ID字段取值。
DEP会话的优先级(class)字段可以简称为优先级字段：用于指示DEP会话的等级或优先级的字段，指示该DEP数据包的优先或等级。DEP会话承载DEP数据，网络设备可以基于该字段来确定DEP数据的数据包在空口传输的优先级。算力可以基于该字段确定DEP会话对应的计算资源的优先级。
源DEP标识(Source DEP ID)字段：可以是源DEP的标识或源DEP的地址，指示DEP数据包的源地址，可唯一标识DEP的源；DEP通讯对端(目的DEP地址标识的端)在回复收到的DEP消息时，将其中的源DEP地址，设置为回复消息的目的DEP地址。
目的DEP标识(Destination DEP ID)字段：可以是目的DEP的标识或目的DEP地址，指示DEP数据包的目的地址，可唯一标识DEP的目标；DEP通讯源端(源DEP地址标识的端)在发送DEP消息时，将DEP消息需要发送的目的DEP端的地址，设置为此字段的值。
DEP有效负载(Payload Data)字段：DEP协议的有效负载数据，可以是DEP信令，或者是DEP需要传送的业务数据。
可以理解的是，表1所示的DEP协议包括的字段仅仅是举例，实际应用中DEP可以包括更多或更少的字段，以上字段的名字和各字段在协议中的位置也是一种实施的举例。在应用本方案时DEP协议可以有不同的字段命名名称和字段排列方式，也可以进一步增加其他一些可选或必选字段来扩展DEP协议的功能，在表1基础上扩展或变形后的DEP协议仍属于本申请实施例保护的范围。
如图3所示，终端设备与算力上的应用可以经过网络设备实现通信。为了更好的理解终端设备与应用之间的通信方式，示例性地，可以将终端设备向算力上的应用发送数据称为上行DEP数据传输，上行DEP数据的终结点在算力中的应用；可以将算力上的应用向终端设备发送数据称为下行DEP数据传输，下行DEP数据的终结点在终端设备，终端设备可以与算力上的一个或多个应用进行双向的数据传输。针对上行通信，终端设备通过无线承载向网络设备发送上行DEP数据，网络设备通过无线承载接收来自终端设备的上行DEP数据。网络设备将无线承载映射到DEP会话，网络设备通过DEP会话将上行DEP数据发送给算力上的应用。针对下行通信，算力上的应用通过DEP会话将下行DEP数据发送给网络设备，网络设备通过DEP会话接收到来自算力上的应用的下行DEP数据后，将DEP会话映射到无线承载，网络设备通过无线承载向终端设备发送该下行DEP数据，终端设备通过无线承载接收来自网络设备的下行DEP数据。可以理解的是，终端设备与算力上的应用之间的控制信令的交互与数据交互类似。
如图4所示，本申请实施例提供的基于DEP协议的通信方法的流程如下所述。该方法可以通过终端设备、网络设备和算力上的应用角度进行描述，以及从三者的交互角度进行描述。该实施例用于建立终端设备与算力之间的DEP会话。DEP会话可以用于传输第一应用的数据，终端设备与算力之间的DEP会话也可以描述为终端设备与第一应用之间的DEP会话。
S401、终端设备向网络设备发送DEP会话建立请求消息，网络设备接收来自终端设备的DEP会话建立请求消息。
DEP会话建立请求用于请求建立终端设备与第一应用之间的DEP会话。
其中，第一应用为部署在算力上的应用。
S402、网络设备向终端设备发送DEP会话的配置信息，终端设备接收来自网络设备的DEP会话的配置信息。
可选的，在S402之后，还可以包括S403。
S403、网络设备基于DEP会话，向算力(或算力上的第一应用)发送来自终端设备的上行DEP数据；
网络设备还可以基于DEP会话向终端设备转发来自算力(或算力上的第一应用)的下行DEP数据。
通过图4实施例，通过建立终端设备与网络设备之间的DEP会话，可以通过DEP会话实现终端设备与第一应用之间的数据直接传送，通过网络设备达到一跳直通，节省终端设备到应用之间数据交互的路径，从而相比现有的边缘计算技术可以进一步减少时延抖动，并在实现同样服务的提下可以降低网络的资源开销。
下面对图4实施例的可能实现方式做举例说明。
S401中DEP会话建立请求消息符合DEP协议，例如，该DEP会话建立请求消息中DEP类型字段的取值可以是2，表示该DEP会话建立请求消息的DEP类型为会话请求信令。DEP会话请求消息的中有效负载(payload data)部分可以携带用于会话认证的信息，如DEP会话需要的应用部署方的信息，又例如终端设备的认证信息。
S402中DEP会话的配置信息中可以包括以下一项或多项信息：DEP会话的标识、第一应用所在算力的DEP地址、算力的算力资源信息、DEP会话优先级或DEP会话的无线承载。
终端设备获取DEP会话的配置信息后，就可以认为完成了DEP会话的建立。之后，终端设备和算力上的第一应用之间可以基于该DEP会话进行DEP数据交互。
终端设备向网络设备通过无线承载发送上行DEP数据，网络设备通过无线承载接收来自终端设备的上行DEP数据后，需要将无线承载映射到DEP会话上，并通过DEP会话向第一应用转发该上行DEP数据。
第一应用通过DEP会话向网络设备发送下行DEP数据，网络设备通过DEP会话接收来自第一应用的下行DEP数据后，需要将该DEP会话映射到无线承载，通过无线承载向终端设备转发该下行DEP数据。
可以看出，网络设备需要具备无线承载和DEP会话的映射功能。可选的，网络设备可以在建立DEP会话时，建立并保存无线承载和DEP会话的关联，或者说建立并保存无线承载和DEP会话的映射关系。
下面通过一和二这两点对无线承载和DEP会话的映射关系进行举例说明。
一、网络设备可以为终端设备配置一个或多个无线承载，该无线承载可以是该终端设备独自占用的，网络设备是针对该终端设备建立的无线承载。当网络设备为终端设备建立多个无线承载时，无线承载可以关联设定的属性。例如，无线承载可以关联QoS。假设终端设备有三种不同QoS要求的计算数据通信需求，那么网络设备可以为该终端设备建立三个无线承载。无线承载1关联QoS1，无线承载2关联QoS2，无线承载3关联QoS3。
例如，终端设备触发V2X通信，V2X通信中有不同类型的通信业务，对应有不同的服务质量要求。比如用于自动驾驶的V2X通信业务的服务质量要求很高，对应QoS1。用于车辆信息收集的V2X通信业务的服务质量要求比较低，对应QoS2。这种情况下，网络设备针对该终端设备的V2X通信业务：为用于自动驾驶的V2X通信业务建立无线承载1，并且无线承载1关联QoS1；为用于车辆信息收集的V2X通信业务建立无线承载2，并且无线承载2关联QoS2。
可以理解的是，无线承载还可以关联其它的属性，其它属性的关联方式与QoS的关联方式是类似的。
示例性地，无线承载和DEP会话的映射关系可以具有以下几种类型。
1)无线承载和DEP会话是一对一的映射关系。
例如，网络设备针对终端设备建立无线承载1。终端设备触发针对计算任务，终端设备请求建立DEP会话，网络设备为该终端设备建立DEP会话1。
针对上行方向：终端设备生成上行DEP数据，通过唯一的无线承载1向网络设备发送上行DEP数据，网络设备通过无线承载1接收来自终端设备的上行DEP数据。网络设备根据无线承载和DEP会话的映射关系，可以唯一确定无线承载1对应的DEP会话1，并通过DEP会话1向第一应用发送该上行DEP数据。
针对下行方向：部署在算力上的第一应用，或第一应用中的某个任务通过DEP会话向网络设备发送下行DEP数据，网络设备通过DEP会话1接收来自算力的下行DEP数据，并根据DEP会话和无线承载的关系，可以唯一确定DEP会话1对应的无线承载1。网络设备通过无线承载1向终端设备发送该下行DEP数据。
2)无线承载和DEP会话是多对一的映射关系。
例如，如图5所示，网络设备针对终端设备建立无线承载1、无线承载2和DEP会话1。无线承载1、无线承载2和无线承载3分别对应QoS1、QoS2和QoS3。终端设备触发针对计算任务，终端设备请求建立DEP会话，网络设备为该终端设备建立DEP会话1。
假设终端设备触发针对第一应用的三个计算任务，三个计算任务具有不同的属性，例如三个计算任务具有不同的QoS要求分别为QoS1、QoS2和QoS3。第一应用的三个计算任务可以映射到单个无线承载上，即DEP会话1可以与无线承载1、无线承载2和无线承载3都具有映射关系。
针对上行方向：终端设备生成上行DEP数据1、上行DEP数据2和上行DEP数据3，假设上行DEP数据1～3对QoS要求分别为QoS1～QoS3，则终端设备分别通过无线承载1、无线承载2和无线承载3发送上行DEP数据1、上行DEP数据2和上行DEP数据3。网络设备通过无线承载1接收上行DEP数据1，通过无线承载2接收上行DEP数据2，通过无线承载3接收上行DEP数据3。无线承载1、无线承载2和无线承载3均与DEP会话1有映射关系，则网络设备将上行DEP数据1、上行DEP数据2和上行DEP数据3都通过DEP会话1发送给算力上第一应用。
针对下行方向，部署在算力上的第一应用产生下行DEP数据，通过第一应用对应的DEP会话1向网络设备发送下行DEP数据1，网络设备通过DEP会话1接收来自第一应用的下行DEP数据1。网络设备确定无线承载1、无线承载2和无线承载3都与DEP会话1具有映射关系，则网络设备可以根据下行数据1的QoS要求，选择与QoS要求相符的无线承载1发送该下行数据1。可选的，网络设备也可以根据负载分担算法的决策，将DEP会话的下行DEP数据分配到不同的无线承载中。
(3)无线承载与DEP会话是一对多的映射关系。
例如，如图6所示，终端设备触发针对计算任务，终端设备请求建立DEP会话，网络设备可以为该终端设备建立多个DEP会话，例如建立DEP会话1、DEP会话2和DEP会话3。网络设备针对终端设备建立无线承载1。无线承载1与DEP会话1、DEP会话2和DEP会话3都具有映射关系。
多个DEP会话可由不同的配置来区分，例如QoS配置不同使得不同的DEP会话呈现不同的能力。无线承载中不同QoS要求的数据包需要根据自身的情况，选择不同特性的DEP会话。DEP会话1、DEP会话2和DEP会话3可以分别关联不同的属性，例如，DEP会话1、DEP会话2和DEP会话3分别对应QoS1、QoS2和QoS3。
针对上行方向，终端设备通过无线承载1向网络设备发送上行DEP数据，网络设备通过无线承载1接收来自终端设备的上行DEP数据。网络设备根据映射关系，确定无线承载1和DEP会话1、DEP会话2和DEP会话3都具有映射关系。则网络设备可以根据上行DEP数据的QoS要求，选择与QoS要求相符的DEP会话发送该上行DEP数据。可选的，网络设备也可以根据负载分担算法的决策，将上行DEP数据分配到不同的DEP会话中。
针对下行方向，部署在算力上的第一应用产生下行DEP数据时，通过第一应用对应的 DEP会话1向网络设备发送下行DEP数据1。网络设备通过DEP会话1接收来自第一应用的下行DEP数据1。网络设备确定DEP会话1与无线承载1具有映射关系，网络设备选择将DEP会话1映射到无线承载1，通过无线承载1发送下行数据。
例如，某个具体任务1产生下行DEP数据，可以根据DEP会话的属性选择具体发送下行DEP数据的DEP会话。例如，按照服务质量要求对应QoS来选择DEP会话。可以根据第一应用产生下行DEP数据的QoS要求，选择与QoS要求相符的DEP会话来发送下行DEP数据。网络设备通过DEP会话接收到算力中任务1的下行DEP数据后，根据映射关系，可以唯一对应到无线承载1，通过无线承载1发送下行DEP数据。
二、网络设备针对DEP任务建立无线承载，一个DEP任务对应一个无线承载。该DEP任务可以涉及一个或多个终端设备，当该DEP任务涉及多个终端设备时，这些终端设备将共享该无线承载。
基于DEP任务的不同，在一个网络设备中，可以同时存在一个或多个DEP粒度的无线承载，每个无线承载可以关联属性，例如每个无线承载所配置的QoS策略可不同。这种场景下，当网络设备处理上下行DEP数据时，需要通过DEP会话中的会话信息来映射到具体的终端设备，会话信息包括DEP会话中明确指示的会话标识，或基于各种协议字段共同组成的可用于会话标识的信息，例如DEP目的地址、DEP源地址等。与第一点描述的终端设备粒度类似，如果出现多个无线承载可选择时，可以基于多个无线承载的不同特性或负载均衡算法，在多个无线承载中，选择一个来承载DEP数据包的发送。
示例性地，无线承载和DEP会话的映射关系可以具有以下几种类型。
1)无线承载与DEP会话是一对一的映射关系。
例如，如图7所示，可以针对DEP任务1建立无线承载1和DEP会话1，无线承载1和DEP会话1具有对应关系。针对DEP任务2建立无线承载2和DEP会话2，无线承载2和DEP会话2具有对应关系。针对DEP任务2建立无线承载2和DEP会话2，无线承载3和DEP会话3具有对应关系。
针对上行方向：终端设备生成DEP任务1的上行DEP数据，通过DEP任务1对应的无线承载1向网络设备发送上行DEP数据，网络设备通过无线承载1接收来自终端设备的上行DEP数据。网络设备根据无线承载和DEP会话的映射关系，可以唯一确定无线承载1对应的DEP会话1，并通过DEP会话1向算力上的第一应用发送该上行DEP数据。
针对下行方向：部署在算力上的第一应用，或第一应用中的具体任务通过DEP会话1向网络设备发送下行DEP数据，网络设备通过DEP会话1接收来自算力的下行DEP数据，并根据DEP会话和无线承载关系，可以唯一确定DEP会话1对应无线承载1。网络设备通过无线承载1向终端设备发送该下行DEP数据。
2)无线承载与DEP会话是一对多的映射关系。
例如，如图8所示，网络设备针对DEP任务1建立无线承载1，针对DEP任务1建立DEP会话1和DEP会话2。那么，无线承载1与DEP会话1和DEP会话2均具有映射关系。
针对上行方向：终端设备生成DEP任务1的上行DEP数据，通过DEP任务1对应的无线承载1向网络设备发送上行DEP数据，网络设备通过无线承载1接收来自终端设备的上行DEP数据。网络设备根据无线承载和DEP会话的映射关系，确定无线承载1与DEP会话1和DEP会话2均具有映射关系，网络设备可以进一步从DEP会话1和DEP会话2 中选择一个DEP会话。例如，网络设备可以根据DEP会话1和DEP会话2的属性进行选择。比如DEP会话1对应QoS1，DEP会话2对应QoS2。网络设备可以根据上行DEP数据的服务质量要求，选择与服务质量要求对应的QoS，进一步选择该QoS对应的DEP会话。假设选择QoS1对应的DEP会话1，网络设备通过DEP会话1向算力上的第一应用发送该上行DEP数据。
针对下行方向：部署在算力上的第一应用或第一应用中的具体任务，通过DEP会话1向网络设备发送下行DEP数据。其中若第一应用对应多个DEP会话时，还可以根据第一应用对应的多个DEP会话的属性进行选择，比如根据与服务质量要求对应的QoS来选择DEP会话。网络设备通过DEP会话1接收到算力中第一应用发送的下行DEP数据后，根据映射关系，可以唯一对应到无线承载1。网络设备通过无线承载1向终端设备发送该下行DEP数据。若任务1产生下行DEP数据，可以通过DEP会话1或DEP会话2向网络设备发送下行DEP数据。可以根据DEP会话1和DEP会话2的属性选择具体发送下行DEP数据的承载。例如，按照服务质量要求对应QoS来选择DEP会话。网络设备通过DEP会话1或DEP会话2接收到算力中任务1的下行DEP数据后，根据映射关系，可以唯一对应到无线承载1。网络设备通过无线承载1向终端设备发送该下行DEP数据。
3)无线承载与DEP会话是多对多的映射关系。
一个无线承载可以映射多个DEP会话，一个DEP会话也可以映射多个无线承载。
例如，如图9所示，针对DEP任务建立DEP会话1和DEP会话2，针对DEP任务建立无线承载1和无线承载2。那么无线承载1可以与DEP会话1和DEP会话2都具有映射关系。无线承载2可以与DEP会话1和DEP会话2都具有映射关系。DEP会话1可以与无线承载1和无线承载2都具有映射关系。DEP会话2可以与无线承载1和无线承载2都具有映射关系。
针对上行方向：终端设备上行DEP数据，通过DEP任务对应的无线承载1(或无线承载2)向网络设备发送上行DEP数据1，网络设备通过无线承载1(或无线承载2)接收来自终端设备的上行DEP数据1。网络设备根据无线承载和DEP会话的映射关系，确定无线承载1(或无线承载2)与DEP会话1和DEP会话2均具有映射关系，网络设备可以进一步从DEP会话1和DEP会话2中选择一个DEP会话。选择DEP会话的方法可以参考上一段的描述。假设选择DEP会话1，网络设备通过DEP会话1向算力上的第一应用发送该上行DEP数据1。
针对下行方向：部署在算力上的第一应用产生下行DEP数据时，通过第一应用对应的DEP会话1(或DEP会话2)向网络设备发送下行DEP数据1。网络设备通过DEP会话1(或DEP会话2)接收来自第一应用的下行DEP数据1。网络设备确定DEP会话1(或DEP会话2)与无线承载1和无线承载2都具有映射关系，则网络设备可以根据无线承载1和无线承载2的属性选择具体发送下行DEP数据1的承载。例如网络设备确定下行DEP数据1的服务质量要求对应QoS1，无线承载1对应QoS1，那么网络设备选择将DEP会话1映射到无线承载1，通过无线承载1发送下行DEP数据1。
需要说明的是，本申请实例中，除了网络设备之外，算力或算力中的应用，还有终端设备，都可以记录映射关系。并在产生数据需要发送、接收或转发时，基于记录的映射关系，将数据通过对应的无线承载或对应的DEP会话来发送。
需要补充说明的是，当无线承载和DEP会话的映射关系为一对多或多对一时，在多个 无线承载中选择传输数据的无线承载时，按照无线承载关联的属性来选择，同样，在多个DEP会话中选择传输数据的DEP会话时，按照DEP会话关联的属性来选择。在另一种可能的实现方式中，网络设备、终端设备或算力也可以根据负载分担算法，将数据分配到无线承载或DEP会话。
基于图4实施例，如图10所示，下面结合具体的应用场景，对本申请实施例提供的基于DEP协议的通信方法做进一步详细描述。本实施例可以是一种DEP会话建立的流程。通过本实施例，能够建立终端设备与算力中的第一应用之间的DEP会话。

S1003和S1004是DEP会话建立过程中的可选步骤。
下面DEP控制单元基于DEP会话建立请求消息，会创建新的DEP会话，具体执行S1005～S1006。在S1006之后执行S1007。或者，DEP控制单元基于DEP会话建立请求消息，会在已有的DEP会话中匹配到适合终端设备的DEP会话，例如，匹配到适合终端设备的DEP会话1，具体执行S1005*～S1006*。在S1006*之后执行S1007。

图10实施例除了与图4实施例对应的步骤之外，其余步骤的部分或全部均为可选步骤，为在图4实施例基础上的进一步可选实现方式。
图4实施例中S403描述了网络设备转发上行DEP数据和/或转发下行DEP数据的流程。以下通过图11描述一下本申请实施例基于DEP协议进行数据传输的方法。该实施例可以与上文中DEP会话建立的流程结合，例如在DEP会话建立之后执行，也可以单独形成本申请要保护的方案。
S1101、终端设备向网络设备发送上行DEP数据，网络设备接收来自终端设备的上行DEP数据。
可选的，基于表1的举例，该上行DEP数据中包括的类型字段的取值可以为3，表示该上行DEP数据的类型为用户数据。该上行DEP数据中的会话标识字段，可以为终端设备已获取的DEP会话标识，例如结合上文中DEP会话建立的流程，若终端设备已从网络设备获取DEP会话的配置信息，该DEP会话的配置信息中包括该DEP会话的标识，则该上行DEP数据中的会话标识字段可以填写为该DEP会话的配置信息中包括的该DEP会话 的标识。
该上行DEP数据消息中的会话优先级字段可以为终端设备已获取的DEP会话优先级。结合上文中DEP会话建立的流程，若终端设备已从网络设备获取DEP会话的配置信息，该DEP会话的配置信息中包括DEP会话优先级，该上行DEP数据消息中会话优先级字段可以填写为该DEP会话的配置信息中携带的DEP会话优先级。如果网络设备没有配置DEP会话优先级，终端设备基于本地的策略进行配置，或者填写缺省优先级。
该上行DEP数据消息中的源DEP标识字段，可以为终端设备已获取的源DEP地址；该上行DEP数据消息中的目的DEP标识字段，可以为终端设备已获取的算力资源地址。其中，结合上文中DEP会话建立的流程，若终端设备已从网络设备获取DEP会话的配置信息，该DEP会话的配置信息中包括源DEP地址和算力资源地址，该上行DEP数据消息中源DEP标识字段和目的DEP标识字段分别可以填写为该DEP会话的配置信息中携带的对应信息。
S1102、网络设备将上行DEP数据发送给算力中的第一应用。算力中的第一应用从网络设备接收该上行DEP数据。
该上行DEP数据可以包括DEP会话标识、源DEP地址和目的DEP地址。其中，源DEP地址为终端设备的DEP地址，目的DEP地址为第一应用所在算力的DEP地址。
可选的，网络设备接收到来自终端设备的该上行DEP数据后，可以基于DEP会话的优先级字段确定DEP会话的优先级，按照该DEP会话的优先级对该上行DEP数据进行调度，并基于其中的会话标识和目的DEP标识，将该上行DEP数据发送给与目的DEP标识对应的算力。
算力中的第一应用收到来自网络设备的该上行DEP数据后，若该上行DEP数据包括DEP会话优先级，则算力可以将DEP会话优先级映射到算力资源的优先级。即按照DEP会话优先级确定算力资源的优先级。映射的策略可以基于DEP控制单元的配置，或者基于网络设备自身的配置或基于标准定义。
S1101～S1102完成了上行DEP数据的传输。
S1103、算力上的第一应用向网络设备发送下行DEP数据，网络设备接收来自第一应用的下行DEP数据。
可选的，基于表1的举例，该下行DEP数据中包括的类型字段的取值可以为3，表示该上行DEP数据的类型为用户数据。该下行DEP数据中还可以包括DEP会话标识。该下行DEP数据中还可以包括优先级字段，该优先级字段基于从终端设备接收的上行DEP数据确定，或者该优先级字段根据本地的策略确定。该下行DEP数据的源DEP标识为算力的DEP地址，目的DEP标识为终端设备的DEP地址。
S1104、网络设备将该下行DEP数据发送给终端设备，终端设备接收来自网络设备的该下行DEP数据。
S1103～S1104完成了下行DEP数据的传输。
上行DEP数据的传输和下行DEP数据的传输可以同时存在，也可以独立存在，例如只存在上行，或只存在下行。
图11实施例描述了上行DEP数据和下行DEP数据的传输，网络设备需要具有转发DEP数据的功能，在转发DEP数据时，需要进行无线承载和DEP会话的映射，将来自终端设备的上行DEP数据映射到DEP会话上，向算力发送。将来自算力上第一应用的下行 DEP数据映射到无线承载上，向终端设备发送。下面通过图12对网络设备映射转发DEP数据的实施例进行详细描述。通过图12实施例，能够基于DEP协议实现终端设备与算力中的第一应用之间的DEP数据传输。图12实施例提供的方法可以结合上文中DEP会话建立流程，在DEP会话建立之后执行，也可以单独形成本申请要保护的方案。图12实施例提供的方法也可以结合图11实施例上下行DEP数据传输的方法执行。下面将与图11实施例的步骤结合进行描述本实施例。
S1201、终端设备确定无线承载。
终端设备在生成上行DEP数据时，需要选择合适的无线承载来传输该上行DEP数据。一种可能的情况是网络设备已将DEP会话对应的无线承载的配置信息发送给终端设备，终端设备可以根据网络设备的配置信息确定无线承载。另一种可能的情况是网络设备没有给终端设备发送无线承载的配置信息，此时需要终端设备判断，是基于已有的无线承载来发送该上行DEP数据，还是需要创建新的无线承载来发送该上行DEP数据。如果需要新的无线承载来发送该上行DEP数据，则终端设备可以使用无线网络标准协议规定的无线承载创建流程，来创建新的无线承载，在新的无线承载创建后，再基于新创建的无线承载发送上行DEP数据。
在终端设备确定无线承载之后，可以执行S1101。终端设备可以通过无线承载向网络设备发送上行DEP数据，网络设备通过无线承载接收来自终端设备的上行DEP数据。
可选的，终端设备在传输上行DEP数据之前，可以向网络设备发送DEP会话优先级，网络设备根据接收的DEP会话优先级，确定上行DEP数据的数据包在空口传输的优先级，并按照该上行DEP数据的数据包在空口传输的优先级进行传输资源配置。例如，终端在传输上行DEP数据之前，可能会向网络设备发送调度请求(scheduling request，SR)，SR中携带DEP会话优先级。网络设备接收SR后，根据SR中携带的DEP会话优先级确定空口传输的优先级，并基于空口传输优先级为终端设备分配传输资源。
根据DEP会话优先级确定空口传输的优先级的策略可以基于DEP控制单元的配置，或者基于网络设备自身的配置或基于标准定义。
S1202、网络设备在收到来自终端设备的上行DEP数据后，建立DEP会话和无线承载的第一映射关系。
如果网络设备在DEP会话创建流程中，已经为述DEP会话配置无线承载，即已建立DEP会话与无线承载的第二映射关系，例如网络设备向终端设备发送的DEP会话的配置信息中包含DEP会话的无线承载，则这种情况下网络设备可以判断第一映射关系与第二映射关系是否一致。如果一致则实施下一步的该上行DEP数据的处理。如果不一致，则基于策略配置，可以向终端设备发送重置消息，要求终端设备按之前配置的无线承载(即第二映射关系)正确发送上行DEP数据，或者创建新的DEP会话和无线承载对应关系，并实施下一步的上行DEP数据处理。
在创建DEP会话和无线承载的第一映射关系之后，可以执行S1102和S1103。
S1203、网络设备在收到来自算力的第一应用的下行DEP数据之后，基于之前建立的DEP会话和无线承载第一映射关系，确定无线承载。
在确定无线承载之后，执行S1104。
网络设备可以根据下行DEP数据中包括的目的DEP标识确定需要转发该下行DEP数据到哪个终端设备。将下行DEP数据发送给终端设备。
基于上述描述，以下通过图13对本申请实例提供的基于DEP的通信方法做进一步详细的描述，本实施例可以是一种DEP注册和地址分配的实施例。通过本实施例，能够对终端设备进行DEP注册和DEP地址分配。该实施例可以作为上文中基于DEP的通信方法的进一步可选实现方式。该实施例可以与上文中DEP会话建立的流程结合，例如在DEP会话建立之前执行，也可以单独形成本申请要保护的方案。
应用部署方在算力中部署了第一应用之后，终端接入和使用该第一应用时，需要经过应用部署方的授权。具体方法如下所述。
S1301、终端设备向网络设备发送DEP注册消息。网络设备接收来自终端设备的该DEP注册消息。
可选的，基于表1的举例，该DEP注册消息中包括的类型字段的取值可以为1，表示该DEP注册消息的类型为DEP注册信令。
S1302、网络设备向DEP控制单元发送DEP认证请求消息，DEP控制单元接收来自网络设备的DEP认证请求消息。
DEP认证请求消息中可以携带的应用部署方信息和/或终端设备的认证信息。
DEP认证请求消息可使用基于DEP的RRC/NAS信令传输。如图2所示，通过RRC层或NAS层向DEP层传输该DEP认证请求消息。NAS层可以在RRC层之上。RRC/NAS消息作为DEP的有效负载(payload data)。如果DEP认证请求消息是基于RRC/NAS实现，则终端设备发送给网络设备时，可以选择SRB来传输DEP认证请求消息，与无线其他RRC/NAS信令消息类似，而不是使用DRB或其他形式的无线承载来传输DEP认证请求消息。
或者，DEP认证请求消息也可以通过DEP定义的DEP专属信令来传输。
S1303、DEP控制单元向应用部署方发送DEP认证请求，应用部署方接收来自DEP控制单元的DEP认证请求。
DEP控制单元基于S1302中接收到的DEP认证请求中携带的应用部署方信息和/或终端设备的认证信息，判断是否需要向应用部署方发起认证请求。如果需要，则DEP控制单元向应用部署方发送DEP认证请求。在DEP认证请求中携带需要鉴权的终端设备的信息，即发起DEP注册的终端设备的信息。
S1304、应用部署方向DEP控制单元返回鉴权消息，DEP控制单元接收来自应用部署方的鉴权信息。
应用部署方在接收到来自DEP控制单元的DEP认证请求后，可以根据该DEP认证请求中的终端设备的信息，对该终端设备进行DEP会话的鉴权认证，并向DEP控制单元返回鉴权消息。
鉴权消息可以是指应用部署方对终端设备授权认证通过。可选的，应用部署方也可以返回鉴权消息，鉴权消息也可以包括是否授权认证通过的结果。
S1303和S1304为可选的步骤。
S1305、DEP控制单元基于鉴权信息，与终端设备、应用部署方共同完成认证流程，具体的认证流程可基于已标准化的认证过程，例如基于EAP-AKA方法。
S1306、DEP控制单元向网络设备发送DEP配置信息，网络设备从DEP控制单元接收该DEP配置信息。
该DEP配置信息可以包括为终端设备分配的DEP地址。DEP地址可以是一个一定长 度(如16bit～256bit)的字符串，由DEP控制单元负责分配和管理。
该DEP配置信息还可以包括该终端设备的优先级配置。
S1307、网络设备向终端设备发送DEP配置信息发送给终端设备，终端设备接收来自网络设备的该DEP配置信息。
网络设备向终端设备发送的DEP配置信息，可以包含上述S1306中DEP配置信息包括的部分或全部内容。除了包含上述S1306中DEP配置信息包括的部分或全部内容之外，可选的，还可以包括无线承载的配置信息。
