通过上述方法，第一节点可以根据自身的目标传输需求，与第二节点之间动态地建立第一传输信道，该第一传输信道不会局限于默认配置，既不会因为默认配置较少条静态传输信道而不能满足传输需求，也不会因默认配置较多条静态传输信道而带来传输资源的不合理占用和浪费，有助于提高传输资源的利用效率，同时还可以满足各种不同的传输需求，适应更丰富的传输场景。
结合第一方面，在一种可能的设计中，所述目标传输需求包括以下一项或多项信息：服务质量QoS参数、传输信道参数、用户等级信息、控制面负荷信息、用户面负荷信息、控制分流信息、第一业务的业务类型、或者第一业务的业务特征信息。

应理解，本申请实施例中，由于第一节点与第二节点之间基于第一请求消息、第一响应消息进行协商以建立所述第一传输信道，针对第一节点在所述第一请求消息中对所述第一传输信道的相关配置，若第二节点同意该配置，则该第二节点向第一节点反馈的第一响应消息中携带的确认信息可以为同样的配置信息，例如第一传输信道的源信道标识与目标信道标识相同。若第二节点不同意该配置，则该第二节点向第一节点反馈的第一响应消息中携带的确认信息可以包括第二节点重新配置的相关配置信息，例如第一响应消息中包含的第一传输信道的目标信道标识，与第一请求消息中包含的第一传输信道的源信道标识不同。在一种可选的设计中，所述第一响应消息中还可以包含所述第一传输信道的源信道标识和/或所述第一承载的源信道标识。

在本申请实施例中，通信装置可以包括但不限于具备短距通信功能的智能手机、笔记本、平板电脑等智能终端、鼠标、键盘、耳机、音响或者车载播放设备等。在存在至少两个通信装置的情况下，为便于区分，也可以将所述至少两个通信装置分别称为第一通信装置、第二通信装置等，相应地，也可以简称为第一装置或第一节点、第二装置或第二节点等。
第一节点和第二节点之间可以通过第一通信技术，例如某种短距离通信技术，实现通信连接。其中，短距离通信技术可以包括但是不限于是蓝牙(bluetooth)技术、无线保真(wireless fidelity，Wi-Fi)技术、近场通讯(near field communication，NFC)技术、Wi-Fi Aware技术、通用短距通信技术等。短距离通信在文件传输、远程控制、投屏、周围设备的感知等各方面有大量应用。下面列举几种短距离通信技术的示例。
蓝牙：一种支持设备短距离通信的无线电技术，能在包括移动电话、无线耳机、笔记本电脑、相关外设等众多设备之间进行无线信息交换。利用“蓝牙”技术，能够有效地简化移动通信终端设备之间的通信，也能够成功地简化设备与因特网之间的通信，从而使得数据传输变得更加迅速高效，为无线通信拓宽道路。
无线保真技术(wireless fidelity，Wi-Fi)：又称为无线局域网(wireless local area networks，WLAN)直连或Wi-Fi Direct，是Wi-Fi协议簇中的一个，使设备之间能够轻松连接彼此而不再需要中介性质的无线接入点。其使用范围从网页浏览到文件传输，以及同时与多个设备进行通信，能够充分发挥Wi-Fi的速度优势。符合此标准的设备即使来自不同的生产厂商，亦可实现轻松互联。
Wi-Fi Aware技术：在Wi-Fi技术中负责感知和发现部分，能够帮助Wi-Fi设备感知周边的服务，比如，周边的设备，进而通过Wi-Fi Aware实现近距离的两个设备的点对点(Peer to Peer，P2P)消息交互。由于WIFI-Aware可以感知周围的设备，所以可实现多种功能，比如，感知的附近的人并建立连接，进而加好友、玩同一款游戏等等；或者，发现周围的设备，实现照片分享或地点分享等等；或者，无需接入网络(比如蜂窝或无线)，就可以向打印机安全地发送文件，等等。
需要说明的是，除了上面列举的三种短距离通信技术之外，现有的其它短距通信技术，或者，随着通信技术的演进，未来可能出现的其他的短距离通信技术，也可以适用于本方案。
可以理解的是，本申请中，也可以在逻辑功能上将所述至少两个通信装置区分为两类节点，即主节点(或者称为授权节点)和从节点。其中，主节点可以管理从节点，具有资源分配能力或资源调度能力，可以为从节点分配资源或配置从节点的相关功能。从节点能够听从主节点的分配或调度，并基于主节点分配的资源进行通信。需要注意的是，主节点和从节点的属性特征可能改变。例如，当智能终端与鼠标进行通信时，智能终端为主节点，鼠标为从节点；但当智能终端接入更高优先级的其它设备并听从其它设备调度时，此时智能终端的角色属性变更为从节点。本申请实施例中，可采用G节点表示授权节点，采用T节点表示从节点。
应理解，本申请中，通信装置也可以为网络设备，例如包括接入网(access network，AN)设备，例如基站(例如，接入点)，可以是指接入网中在空口通过一个或多个小区与无线终端设备通信的设备，或者例如，一种车到一切(vehicle-to-everything，V2X)技术中的网络设备为路侧单元(road side unit，RSU)。基站可用于将收到的空中帧与IP分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。RSU可以是支持V2X应用的固定基础设施实体，可以与支持V2X应用的其他实体交换消息。网络设备还可协调对空口的属性管理。例如，网络设备可以包括LTE系统或高级长期演进(long term evolution-advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括第五代移动通信技术(the 5th generation， 5G)NR系统(也简称为NR系统)中的下一代节点B(next generation node B，gNB)或者也可以包括云接入网(cloud radio access network，Cloud RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，本申请实施例并不限定。
网络设备还可以包括核心网设备，核心网设备例如包括5G系统中的访问和移动管理功能(access and mobility management function，AMF)、会话管理功能(session management function，SMF)或用户面功能(user plane function，UPF)等，或者包括4G系统中的移动管理实体(mobility management entity，MME)等。
(2)通信协议架构
以短距通信技术为例，如图1所示，短距通信技术的通信协议架构可包括应用层(application layer)、服务层(service layer)和接入层(access layer)，每个层可称为协议层。
应理解，这里的层只是一种框架性的结构划分，整体上分为上层、中层和底层三个大层。不同的通信系统可以有各自的层划分方式，也可以有更具体和下位的层次划分，这里不做具体限定。例如，现有技术还存在七层、五层和三层等多种可能的网络模型。其中，每个层的功能可以通过一种或者多种协议实现。例如服务层的协议可以包含IPv4等，接入层的协议可以包含逻辑链路控制与适配(logical link control&adaption protocol，L2CAP)层和/或链路(link，LL)层等。
应用层位于服务层之上，可以部署若干应用程序(application)/业务实例，可用于为应用程序(也称为应用或用户)提供服务，例如通用通信服务、通用音视频服务、主动降噪服务、文件服务等。可选地，应用层还可用于为用户提供会话支持和/或信息支持。
服务层位于接入层之上，用于在源节点(例如第一节点)和目的节点(例如第二节点)之间建立连接，并提供端到端的信息传输服务。可选地，服务层可对应网络层(network layer)、数据传输与适配层，该网络层可以负责进行传输控制和路由选择，以为不同的功能(例如设备发现、服务发现、连接管理、QoS管理、安全管理、多域管理、测量管理、5G融合等)确定传输承载(或者称为传输信道)。可选地，网络层还可以进行流量控制。数据传输与适配层，可用于对上层传递的数据(包括透传数据和非透传数据)进行编码或解码，从而将数据转换为兼容或适合传输的格式。
接入层可以为节点之间的通信提供通信接口/手段，接入层可能包含多种不同的接入技术，不同的接入技术可能对应不同的通信接口，例如蜂窝接口，WIFI接口等。可选地，接入层对应数据链路层和物理层。
数据链路层：保障在物理链路上进行数据的可靠传递。数据或指令被封装成特定的可被物理层传输的帧；可选地，数据链路层还包括访问控制、资源管理、数据分段、级联、纠错等功能。比如，以蓝牙协议为例，数据链路层可以包括逻辑链路控制和适配协议(logical link control and adaptation protocol，L2CAP)层和逻辑(logical layer，LL)层。其中，L2CAP负责进行数据封装、分段、逻辑信道管理等功能；LL层负责进行资源管理和分配。其中，数据链路层可包括一个或多个接入层承载(或称为链路信道、逻辑信道)，用于传输来自上层(例如服务层)的数据或指令。
物理层：利用传输介质为数据链路层提供物理连接，实现比特流的透明传输。一般地，物理层进行信道编码或解码，保障数据传输的可靠性。
由于服务层可能存在不同的网络和/或传输协议，因此，数据链路层还可用于提供与不 同的网络和/或传输协议之间的传输适配功能。比如，接收来自底层(数据链路层之下的协议层)的数据包，区分该数据包所属的上层(数据链路层之上的协议层)协议类型，并将该数据包递交(或称传递)给对应的上层协议处理。需要说明的是，数据链路层是一个逻辑功能层，在实现上，其也可以包含在服务层中，本申请不对此进行限制。
应理解，本申请中协议层的上层是指，该协议层的之上的任意一个协议层，比如，L2CAP层的上层，可以是服务层或应用层。其中，上层向下层传输数据包的过程，可称为传递。下层向上层传输数据包的过程可称为递交。
在每一协议层，需要对上层传递的数据包打上相应的数据包包头(或称为帧头)，从而便于对端节点的对等层对其进行解析，比如，发送端节点的LL层在数据包上添加LL层包头，需要在接收端节点的LL层对该LL包头进行解析。
本申请实施例中，对于上层传递下来的数据包，在未加包头之前，可将该数据包称为服务数据单元(service data unit，SDU)，加包头之后称之为协议数据单元(protocol data unit，PDU)。比如，LL层接收到的L2CAP层传递的数据包可称为LL SDU(也称为L2CAP PDU)；在LL对该数据包添加包头后，添加包头后的数据包称为LL PDU。相反，在接收端，LL可对接收到的LL PDU(也称为PHY SDU)进行去除包头，获得LL SDU，并将LL SDU递交给上层。
可以理解的，在发送端，如果该任一协议层对数据进行透传，则该协议层生成的PDU仅包含SDU。其中，对于数据的发送端，透传是指该协议层不对来自于上层的本层SDU(也称为上层PDU)进行封装包头的处理，直接将本层SDU作为本层PDU传递到下层。透传又可称为透明传输或pass-through，可以理解透传是指在通信中不对业务数据内容做改变，例如不对数据进行分段、级联、拼接、重排序、加包头等动作，将原始内容由源地址传输到目的地址。在数据的接收端，透传是指，该协议层不对下层递交的下层SDU(也称为本层PDU)则进行解封装处理，直接将本层PDU作为本层SDU递交到上层。
在一种可选的设计中，在透传时，发送端协议层(如LL层)可以对传输数据进行加密，接收端协议层(如LL层)可对数据进行解密。其中加密和解密所使用的算法、参数等可以是发送端节点与接收端节点双方预先约定的或协议中定义的。
在一种可选的设计中，在透传时，发送端协议层可以对传输数据添加循环冗余校验(cyclic redundancy check，CRC)校验码，用于接收端对应的协议层对数据进行校验。其中，CRC校验运算使用的算法、参数可以是G节点与T节点双方预先约定的或协议中定义的。CRC校验码可添加在传输数据的尾部。
(3)协议和协议栈
本申请实施例中，每个协议层可支持一种或多种协议，每个协议层的一种协议对应于一个协议栈。
其中，协议与协议栈不同。协议是执行主体需要遵从的一组约定，协议栈是通过协议对数据进行处理的单元或者模块，协议栈产生的数据经过下层(例如接入层)处理后发送。本申请实施例中，协议栈也可以简单理解为G节点或T节点中能使用协议对数据进行处理的单元或模块。
以T节点为例，假设第一协议栈支持第一协议，即第一协议栈是T节点中使用第一协议对数据进行处理的单元或模块。同理，假设第二协议栈支持第二协议，即第二协议栈可以是T节点中的使用第二协议对数据进行处理的单元或模块。其中，第一协议栈和第二协 议栈可以是同一个单元或不同单元，本申请实施例不作限定。
应理解，在不同的协议栈中，应用层、服务层、接入层等协议层可进一步细分为不同的协议层，用于实现相同或相似功能的相应协议层也可以具有不同的名称，本申请对此不做限定。本申请实施例中的协议不仅仅限定为用于通信的协议。
(4)逻辑信道
一般地，不同的业务往往具有不同的服务质量(Quality of Service，Qos)需求，因此可以为不同的业务建立不同的逻辑信道，从而保障不同业务的差异化Qos需求。例如，为音频业务、视频业务分别建立不同的逻辑信道。
以单个逻辑信道只对应一种业务为例。比如，逻辑信道1对应业务①，逻辑信道2对应业务②。业务①的数据不能复用逻辑信道2，同样，业务②的数据不能复用逻辑信道1。一般，不同逻辑信道对应不同传输资源，比如，逻辑信道1对应传输资源1，逻辑信道2对应传输资源2，传输资源1和传输资源2不同。比如，传输资源1和传输资源2的时域资源不同(如，短距离通信系统是时分系统，那么传输资源1和传输资源2是时分的)。
当然，可以理解的，也可以为Qos需求相近的一个或者多个业务建立相同的逻辑信道，从而减少逻辑信道数量，便于管理。
更广义的逻辑信道概念为：根据物理信道传输内容的不同划分的多个虚拟信道，即物理信道是真正完成传输工作的，逻辑信道是来界定传输内容的。例如，逻辑信道可以分为两类：控制信道和业务信道，控制信道用于传输控制平面信息，而业务信道用于传输用户面信息(例如业务数据)。
本申请实施例中，接入层承载可以为逻辑信道，具有逻辑信道标识(Logical Channel Identifier，LCID)。
(5)至少一个，是指一个，或一个以上(包括多个，指两个或两个以上)，即包括一个、两个、三个及以上。
(6)携带，可以是指一个消息用于承载信息或数据，也可以是指该消息由哪些信息构成，或者消息中包含哪些信息。
(7)“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
下面介绍本申请实施例适用的通信系统。
图2示出了本申请实施例适用的通信系统的示意图。参阅图2所示，该通信系统中可以包括第一节点210和第二节点220。其中，第一节点210可以为终端节点，第二节点220可以为所述第一节点210的授权节点，第一节点210和第二节点220均可支持第一通信技术，第一节点210和第二节点220可以组成第一通信系统，双方之间可以采用第一通信技术进行通信。
在一种可选的设计中，该通信系统中还可以包括第三节点230。第二节点220和第三节点230均可支持第二通信技术，第二节点220和第三节点230可以组成第二通信系统，双方之间可以采用第二通信技术进行通信，第一通信技术和第二通信技术不同。在该第一 通信技术和第二通信技术的融合通信场景中，第一通信系统与第二通信系统之间可以建立通信连接，组成异构式通信系统，所述第一节点210、所述第二节点220和所述第三节点230可以在该异构式通信系统中执行相应的通信业务和/或传输通信业务数据。
参阅图3所示，以第一通信技术为短距通信技术、第二通信技术为5G通信技术为例，该第三节点230可以包括但不限于接入网设备：例如可信的非第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)网关功能(Trusted Non-3GPP Gateway Function，TNGF)、以及核心网设备：例如SMF、AMF、UPF以及数据网络(Data Network，DN)等功能实体中的至少一项。
各个节点或功能实体之间可以通过接口连接，接口的序列号或接口的名称本申请实施例中不作限定，可以按照5G系统的3GPP相关标准协议中定义的接口，也可以使用未来通信系统中的接口。例如，第二节点220可以通过Yt接口与第一节点210通信，第一节点210可以通过Ta接口与TNGF通信，第二节点220可以通过NWt接口与TNGF通信。第二节点220、第一节点210可以通过下一代网络(next generation，N)1接口(简称N1)与AMF通信，网络设备(例如TNGF)通过N2接口(简称N2)与AMF通信，TNGF通过N3接口(简称N3)与本地UPF通信，UPF通过N6接口(简称N6)与DN通信。AMF通过N11接口(简称N11)与SMF通信，SMF通过N4接口(简称N4)与UPF通信。由此，使得5G网络能够透过该第一节点210来感知该第二节点220的设备状态、网络状态、业务状态等关键信息，达到远程对行业现场网络和业务的可达、可感、可管等。
需要说明的是，上述仅是示意性表示该异构式通信系统中可以包括第一节点210、第二节点220和第三节点230，以及各个节点及其功能模块之间的通信方式，并不限定各个节点的数量以及接口的序列号或名称。在具体实施时，第一节点210、第二节点220、第三节点230的数量可以不限于1个。
另外，需要说明的是，本申请实施例中，第二节点220可以和第三节点230进行无线资源控制(radio resource control，RRC)建立过程，当第二节点220和第三节点230建立了RRC连接后，该第二节点220的RRC状态即为RRC连接态。随后，第二节点220的RRC状态可以在以下状态中进行转换：RRC空闲(RRC_IDLE)态、RRC连接(RRC_CONNECTED)态和RRC非激活(RRC_INACTIVE)态。在本申请实施例的融合通信场景中，该第二节点220可以是处于上述的空闲态、连接态、非激活态中的任一状态，本申请实施例对此不做限定。
上述图2和图3所示的通信系统可用于实现本申请实施例的通信方法，下面结合附图及实施例介绍本申请实施例的通信方法。
图4示出了本申请实施例的通信方法的流程示意图。参阅图4所示，该通信方法可以包括以下步骤：
S410：第一节点确定所述第一节点的目标传输需求。
本申请实施例中，第一节点的目标传输需求为第一节点实现传输服务(包括控制面传输服务和/或用户面传输服务)的需求，该目标传输需求可以根据该第一节点的应用层或服务层或接入层的相关参数确定，也可以根据该第一节点的第一业务确定，本申请实施例对此不做限定。
示例地，该目标传输需求可以包括以下一项或多项信息：应用层服务质量(Quality of  Service，QoS)参数，包括但不限于采用率、采用位宽、音视频编码等；传输信道参数，包括但不限于优先级、包延时、包错误率、时延抖动、吞吐率等；用户等级信息；控制面负荷信息；用户面负荷信息；控制分流信息(例如向不同的通信节点分流)；第一业务的业务类型；或者第一业务的业务特征信息。
S420：第一节点根据所述目标传输需求确定是否建立第一传输信道，所述第一传输信道用于与第二节点通信。
在具体实施过程中，该第一节点可以根据所述目标传输需求是否满足动态信道建立条件，确定是否需要建立所述第一传输信道，该动态信道建立条件可以包括但不限于建立所述第一传输信道应满足的带宽条件、保障速率条件、时延条件等，本申请实施例对此不做限定。若不需要建立所述第一传输信道，则该第一节点可以直接复用第一节点与第二节点之间已存在、且满足所述目标传输需求的传输信道作为所述第一传输信道，而无需动态建立所述第一传输信道；若需要建立所述第一传输信道，则该第一节点可以触发动态地建立所述第一传输信道的流程，以基于所建立的第一传输信道与所述第二节点通信。该建立动态传输信道的过程将在下文中详述，在此暂不赘述。
进一步地，S430：第一节点可以向第二节点发送第一请求消息，所述第一请求消息用于请求建立所述第一传输信道。
示例地，该第一请求消息中可以包括以下至少一项配置信息：所述第一传输信道的地址信息、所述第一传输信道的源信道标识、与所述第一传输信道关联的第一承载的源信道标识、所述第一传输信道的QoS参数的标识。
其中，所述第一传输信道的地址信息可用于路由，例如该第一传输信道是为哪个功能模块建立的，该地址信息可以为相应功能模块的模块标识，以便在基于该第一传输信道于对端节点进行信息传输时，可以知悉信息来源于哪个功能模块、或者来自对端节点的信息需要发送给哪个功能模块。
所述第一传输信道的源信道标识是指承载在请求方发送给响应方的请求消息中的传输信道标识，“源”表示承载该信道标识的消息的传输方向，即是由请求方(即源节点)发送至响应方(即目标节点)的，其中，并不限定该第一节点为源节点、第二节点为目标节点，在一些实施例中，若第一节点和第二节点的角色互换，即第二节点作为请求方、第一节点作为响应方，则第二节点向第一节点发送的第一请求消息中携带的信道标识可称为“源信道标识”。相似地，所述第一承载的源信道标识也是指承载在请求方发送给响应方的请求消息中的接入层承载的信道标识，“源”表示承载该信道标识的消息的传输方向，即是由请求方发送至响应方的，其中，也不限定该第一节点为源节点、第二节点为目标节点，在一些实施例中，若第一节点和第二节点的角色互换，即第二节点作为请求方、第一节点作为响应方，则第二节点向第一节点发送的第一请求消息中携带的信道标识可称为“源信道标识”。同样地，“目标”表示承载该信道标识的消息的传输方向，即是由响应方发送至请求方的，在此不再赘述。
所述第一传输信道的QoS参数，即表示需要为该第一节点建立的第一传输信道的QoS参数，所述QoS参数的标识可用于指示该QoS参数，例如，该QoS参数的标识可以是对应于一组QoS参数的XQI值(X例如可以取值为5，表示5G)。
应理解，本申请实施例中，上述至少一项配置信息仅是对第一节点可能为待建立的第一传输信道配置的相关信息的示例说明，并不限定第一节点的配置能力，在其它实施例中， 该第一请求消息中还可以包含第一节点为该第一传输信道配置的其它信息，在此不再赘述。
S440：第一节点接收来自所述第二节点的第一响应消息，所述第一响应消息用于确认建立所述第一传输信道。
本申请实施例中，所述第一响应消息是所述第二节点针对所述第一请求消息做出的应答。示例地，该第一响应消息可以包括以下至少一项确认信息：所述第一传输信道的地址信息、所述第一传输信道的目标信道标识、与所述第一传输信道关联的第一承载的目标信道标识。
其中，在该第一响应消息中，所述第一传输信道的地址信息与所述第一请求消息中携带的所述第一传输信道的地址信息相同，表示该第二节点同意该第一传输信道的地址信息。在该第一响应消息中，所述第一传输信道的目标信道标识可以与所述第一请求消息中携带的所述第一传输信道的源信道标识相同，表示该第二节点同意第一节点为该第一传输信道配置的传输信道标识；或者，所述第一传输信道的目标信道标识可以与所述第一请求消息中携带的所述第一传输信道的源信道标识不同，表示该第二节点不同意第一节点为该第一传输信道配置的传输信道标识，而重新配置第三传输信道代替第一传输信道，用于第一节点与第二节点之间的通信，该目标信道标识即为该第三传输信道的信道标识。在一种可选的设计中，该第一响应消息中还可以携带所述第一传输信道的源信道标识(从所述第一请求消息中获得)，以便同时向第一节点告知需要将请求配置的第一传输信道替换为所述第三传输信道。相似地，与所述第一传输信道关联的第一承载的目标信道标识，也可以与所述第一请求消息中携带的所述第一承载的源信道标识相同或不同，可选地，该第一响应消息中也可以携带所述第一承载的源信道标识。
由此，通过上述方法，第一节点可以按照自身的目标传输需求，动态地与第二节点之间协商、建立第一传输信道，不会静态占用传输资源，有助于提高传输资源的利用效率，同时还可以满足各种不同的传输需求，适应更丰富的传输场景。
在具体实现过程中，本申请实施例的通信方法的具体实现步骤有所不同，为了便于理解，下面结合不同的情形进行详细介绍。
情形1：第一节点的接入层和第二节点的接入层之间存在满足目标传输需求的第一承载。
参阅图5a所示，第一节点的通信协议架构可以包括应用层、服务层和接入层，第二节点的通信协议架构可以包括应用层、服务层和接入层，第一节点的服务层可以决策是否需要建立第一传输信道，在确定需要建立第一传输信道的情况下，第一节点的服务层可以向第一节点的接入层发送接入层信道建立请求消息，该接入层信道建立请求消息可用于请求配置满足目标传输需求的第一承载。
第一节点的接入层响应于该接入层信道建立请求消息，可以首先确定是否存在满足所述目标传输需求的第一承载。在存在的情况下，第一节点的接入层可以在已经存在的承载中确定所述第一承载，并向第一节点的服务层反馈接入层信道响应消息，以向第一节点的服务层告知可用的、满足所述目标传输需求的第一承载。进而，第一节点的服务层可以基于该第一承载，向第二节点的服务层发送动态信道建立请求消息、以及接收来自第二节点的服务层的动态信道建立响应消息，以与第二节点之间协商、动态地建立第一传输信道。可选地，该第一承载还可以关联默认配置的第二传输信道，该第二传输信道与该动态建立的第一传输信道均可以映射到所述第一承载。应理解，图5a中虚线箭头仅表示相应协议层 之间可以进行信息交互，并不限定交互的信息。
参阅图5b所示，该通信方法可以包括以下步骤：
在一种可选的设计中，该通信方法可由第一节点的应用层触发。S501(可选)：第一节点的应用层可以确定所述第一节点的目标传输需求，并判决是否需要建立第一传输信道，在确定需要建立所述第一传输信道的情况下，第一节点的应用层可向第一节点的服务层发送第二请求消息。相应地，第一节点的服务层可以接收来自第一节点的应用层的第二请求消息。其中，该第二请求消息可用于指示所述目标传输需求，例如，该第二请求消息中可以包含应用层QoS参数。S502：第一节点的服务层可根据来自所述第一节点的服务层的第二请求消息确定是否建立所述第一传输信道。
在另一种可选的设计中，该通信方法可由第一节点的服务层触发。S502：第一节点的服务层可以确定第一节点的目标传输需求，并根据所述目标传输需求确定是否建立所述第一传输信道。
根据S502的判决结果，在判决结果为是，即确定建立所述第一传输信道的情况下，进入S503。在确定不建立所述第一传输信道的情况下，则可以根据所述第一节点的目标传输需求直接复用第一节点和第二节点之间已存在的传输信道。
S503：第一节点的服务层向第一节点的接入层发送第三请求消息，所述第三请求消息用于请求配置满足目标传输需求的第一承载。相应地，第一节点的接入层接收来自所述第一节点的服务层的第三请求消息。
S504：第一节点的接入层根据所述第三请求消息，确定是否需要建立所述第一承载。
例如，第一节点的接入层可以在预先配置的或者预定义的第一节点与第二节点的承载中确定是否存在满足目标传输需求的第一承载。
如果存在，则不需要建立所述第一承载，第一节点的接入层可以在预先配置的或者预定义的第一节点与第二节点的承载中确定所述第一承载，之后进入S505。
S505：第一节点的接入层向第一节点的服务层发送第三响应消息，所述第三响应消息用于确认配置所述第一承载。相应地，第一节点的服务层接收来自第一节点的接入层的第三响应消息。示例地，该第三响应消息中包含所述第一承载的标识。
S506：第一节点的服务层向第二节点的服务层发送第一请求消息。相应地，第二节点的服务层接收所述第一请求消息。
示例地，该第一请求消息包括以下至少一项配置信息：所述第一传输信道的地址信息、所述第一传输信道的源信道标识、与所述第一传输信道关联的第一承载的源信道标识、QoS参数的标识。应理解，本申请实施例中，源信道标识仅表示数据信息传输方向，例如第一传输信道的源信道标识表示数据信息传输由第一节点到第二节点方向的标识，第一承载的源信道标识表示数据信息传输由第一节点到第二节点的标识，并不限定第一节点为源节点或第二节点为目标节点。在一些设计中，第一传输信道可以只有一个信道标识，而不区分源信道标识或目标信道标识，在该情形下，第一请求消息中的源信道标识即为相应信道的信道标识，下文中不再逐一区分。
S507：第二节点的服务层与接入层之间确认QoS参数、以及第一传输信道和第一承载之间的映射关系。
S508：第二节点的服务层向第一节点的服务层发送第一响应消息。相应地，第一节点的服务层接收所述第一响应消息。
示例地，该第一响应消息包括以下至少一项确认信息：所述第一传输信道的地址信息、所述第一传输信道的目标信道标识、与所述第一传输信道关联的第一承载的目标信道标识。可选地，该第一响应消息中还可以包括所述第一传输信道的源信道标识、与所述第一传输信道关联的第一承载的源信道标识。
应理解，此处述及的目标信道标识仅表示数据信息传输方向，例如第一传输信道的目标信道标识表示数据信息传输由第二节点到第一节点的标识，第一承载的目标信道标识表示数据信息传输由第二节点到第一节点的标识，并不限定第一节点为源节点或第二节点为目标节点。
S509：第一节点的服务层可以建立(或者称为维护)以下至少一项映射关系：所述第一传输信道与业务类型之间的映射关系、所述第一传输信道与QoS参数之间的映射关系、所述第一传输信道与关联的第一承载之间的映射关系，所述第一传输信道与节点类型之间的映射关系。
S510(可选)：第一节点的服务层与第一节点的接入层之间同步所述至少一项映射关系。示例地，在实施S510时，第一节点的服务层可以向所述第一节点的接入层发送指示信息，该指示信息可用于指示所述至少一项映射关系。
S511(可选)：第一节点的服务层与第一节点的应用层之间同步所述至少一项映射关系。在实施S511时，第一节点的服务层可以向所述第一节点的应用层发送指示信息，该指示信息可用于指示所述至少一项映射关系。
需要说明的是，本申请实施例中，第一节点的服务层可以将维护的至少一项映射关系分别同步给第一节点的接入层和应用层。或者，第一节点的服务层可以本身记录完整的各个映射关系信息，并根据接入层或应用层的需要，分别向该接入层或应用层发送用于指示所建立的第一传输信道与其他信息之间的映射关系。比如，该第一传输信道是与第一承载绑定的，第一节点的接入层需要知悉第一传输信道与第一承载之间的映射关系，以便将经过所述第一传输信道和所述第一承载的数据通过相应的空口发送，故而，第一节点的服务层可能需要向第一节点的接入层告知所述第一传输信道与所述第一承载之间的映射关系。一般地，第一节点的服务层可以在建立所述至少一项映射关系后，即向第一节点的接入层发送相应的指示信息。又比如，若本申请实施例的动态建立第一传输信道的流程是由第一节点的应用层触发的，则该第一节点的服务层可能需要根据应用层提供的目标传输需求，向第一节点的应用层告知该第一传输信道与相应目标传输需求之间映射关系，例如所述第一传输信道与业务类型之间的映射关系、所述第一传输信道与QoS参数之间的映射关系等，以便应用层在实现业务时能够知悉经由哪个传输信道向下层传递信息。一般地，第一节点的服务层可以根据是否接收到来自第一节点的服务层的第二请求消息确定是否执行S511。
S512：第一节点的服务层确定释放或者去激活所述第一传输信道，向所述第二节点发送第五请求消息，所述第五请求消息用于指示释放或者去激活所述第一传输信道。相应地，所述第二节点的服务层接收所述第五请求消息。
本申请实施例中，第一节点的服务层可以在该第一传输信道满足相应的释放条件或去激活条件时，确定释放或者去激活(即挂起动态信道配置)所述第一传输信道。示例地，该释放条件或去激活条件例如可以包括：所述第一传输信道在第一时间段T内没有数据传输。应理解，对于已经释放或者去激活的第一传输信道，在第一节点的目标传输需求再次为需要建立第一传输信道时，还可以激活或恢复所述第一传输信道，在此不再赘述。
情形2：第一节点的接入层和第二节点的接入层之间不存在与所述第一传输信道关联的第一承载。
如图6a所示，第一节点的通信协议架构可以包括应用层、服务层和接入层，第二节点的通信协议架构可以包括应用层、服务层和接入层，第一节点的服务层可以决策是否需要建立第一传输信道，在确定需要建立第一传输信道的情况下，第一节点的服务层可以向第一节点的接入层发送接入层信道建立请求消息，该接入层信道建立请求消息可用于请求配置满足目标传输需求的第一承载。
第一节点的接入层响应于该接入层信道建立请求消息，可以首先确定是否存在满足所述目标传输需求的第一承载。在不存在的情况下，第一节点的接入层可以向第二节点的接入层上报辅助信息、以及接收来自所述第二节点的接入层的重配消息，以配置所述第一承载；或者，所述第一节点的接入层可以接收来自所述第二节点的接入层的重配消息，该重配消息用于配置所述第一承载。
在该第一承载配置完成后，第一节点的接入层可以向所述第一节点的服务层反馈接入层信道响应消息，以向第一节点的服务层告知可用的、满足所述目标传输需求的第一承载。进而，第一节点的服务层可以基于所配置的第一承载，向第二节点的服务层发送动态信道建立请求消息、以及接收来自第二节点的服务层的动态信道建立响应消息，以与第二节点之间协商、动态地建立第一传输信道。可选地，该第一承载可以关联默认配置的第二传输信道，在该第一承载建立后，该第二传输信道可以自动激活，并用于第一节点与第二节点之间的通信。应理解，图6a中虚线箭头仅表示相应协议层之间可以进行信息交互，并不限定交互的信息。
参阅图6b所示，该通信方法可以包括以下步骤：
在一种可选的设计中，该通信方法可由第一节点的应用层触发。S601(可选)：第一节点的应用层可以确定所述第一节点的目标传输需求，并判决是否需要建立第一传输信道，在确定需要建立所述第一传输信道的情况下，第一节点的应用层可向第一节点的服务层发送第二请求消息。相应地，第一节点的服务层可以接收来自第一节点的应用层的第二请求消息。其中，该第二请求消息可用于指示所述目标传输需求，例如，该第二请求消息中可以包含应用层QoS参数。S602：第一节点的服务层可根据来自所述第一节点的服务层的第二请求消息确定是否建立所述第一传输信道。
在另一种可选的设计中，该通信方法可由第一节点的服务层触发。S602：第一节点的服务层可以确定第一节点的目标传输需求，并根据所述目标传输需求确定是否建立所述第一传输信道。
根据S602的判决结果，在确定建立所述第一传输信道的情况下，进入S603。在确定不建立所述第一传输信道的情况下，则可以根据所述第一节点的目标传输需求直接复用第一节点和第二节点之间已存在的传输信道。
S603：第一节点的服务层向第一节点的接入层发送第三请求消息，所述第三请求消息用于请求配置满足目标传输需求的第一承载。相应地，第一节点的接入层接收来自所述第一节点的服务层的第三请求消息。
S604：第一节点的接入层根据所述第三请求消息，确定是否需要建立所述第一承载。
例如，第一节点的接入层可以在预先配置的或者预定义的第一节点与第二节点的承载 中确定是否存在满足目标传输需求的第一承载。
如果不存在，则需要建立所述第一承载，此情形下，进入S605，第一节点的接入层与第二节点协商、以配置所述第一承载。
其中，在第一节点与第二节点之间协商配置所述第一承载的情况下，该协商流程可以是第一节点请求触发的，也可以是第二节点主动为第一节点配置的，包括以下步骤：
示例1，第一节点根据所述目标传输需求向第二节点请求配置所述第一承载。
S605：第一节点的接入层向第二节点的接入层发送第四请求消息，该第四请求消息用于请求配置所述第一承载。相应地，第二节点的接入层接收所述第四请求消息。
示例地，该第四请求消息中可以包含以下辅助信息中的一项或多项：第一业务的业务类型，包括但不限于设备发现、服务发现、连接管理、QoS管理、安全管理、5G融合、多域协调、测量管理等；QoS参数的标识(例如XQI值，每一个XQI值可对应一组QoS参数，如下表1所示)；第一业务的业务特征，包括但不限于如采样率、编码等。
表1
Figure PCTCN2022117651-appb-000001
其中，表1中，每一行中“XQI值”为一个标识，“默认优先级”、“包延时预算”、“包错误率”，为该XQI值对应的一组QoS参数，“典型业务”表示传输需求需要与该组QoS参数对应的一些业务的示例。其中，“默认优先级”表示QoS流之间的资源分配的相对重要性，包延迟预算表示数据包可能被延迟的时间的上限，包错误率表示数据包的速率的上限。需要说明的是，本申请实施例中，XQI值对应的一组QoS参数还可以包括时延抖动、吞吐率等，在此不再赘述。
S606：第二节点的接入层、服务层与应用层之间，根据第四请求消息中携带的辅助信息进行QoS策略确认，以为第一节点配置所述第一承载。
S607：第二节点的接入层向第一节点的接入层发送第四响应消息，该第四响应消息用于确认配置所述第一承载。
示例2：第二节点主动向第一节点下发重配消息来配置所述第一承载。
S608：第二节点的接入层向第一节点的接入层发送重配消息。相应地，第一节点的接入层接收来自所述第二节点的接入层的重配消息。所述重配消息用于指示配置所述第一承 载。
需要说明的是，本申请实施例中，所述第一节点可以在向所述第二节点侧注册或者授权时，上报自身的一些基本参数，例如节点类型、业务类型、QoS参数、用户等级信息、控制分流信息等。在第二节点主动触发动态信道建立流程的情况下，该第二节点可以根据第一节点之前上报的相关参数，主动为所述第一节点配置第一承载，并向所述第一节点下发重配消息，以便所述第一节点可以将所述第一承载与待建立的第一传输信道绑定，从而动态地建立所述第一传输信道。
进一步地，S609：第一节点的接入层向第一节点的服务层发送第三响应消息，所述第三响应消息用于确认配置所述第一承载。相应地，第一节点的服务层接收来自第一节点的接入层的第三响应消息。示例地，该第三响应消息中包含所述第一承载的标识。
S610：第一节点的服务层向第二节点的服务层发送第一请求消息。相应地，第二节点的服务层接收所述第一请求消息。详细实现可参见上文中S506的相关描述，在此不再赘述。

S612：第二节点的服务层向第一节点的服务层发送第一响应消息。相应地，第一节点的服务层接收所述第一响应消息。详细实现可参见上文中S508的相关描述，在此不再赘述。
S613：第一节点的服务层建立以下至少一项映射关系：所述第一传输信道与业务类型之间的映射关系、所述第一传输信道与QoS参数之间的映射关系、所述第一传输信道与关联的第一承载之间的映射关系，所述第一传输信道与节点类型之间的映射关系。
S614(可选)：第一节点的服务层与第一节点的接入层之间同步所述至少一项映射关系。详细实现可参见上文中S510的相关描述，在此不再赘述。
S615(可选)：第一节点的服务层与第一节点的应用层之间同步所述至少一项映射关系。详细实现可参见上文中S511的相关描述，在此不再赘述。
S616：第一节点的服务层确定释放或者去激活所述第一传输信道，向所述第二节点发送第五请求消息，所述第五请求消息用于指示释放或者去激活所述第一传输信道。相应地，所述第二节点的服务层接收所述第五请求消息。具体实现可参见上文中S512的相关介绍，在此不再赘述。
由此，通过图5b、图6b所示的方法流程图，第一节点的服务层可以根据自身的目标传输需求，与第二节点的之间进行协商，以动态地建立第一传输信道，不会静态占用传输资源，有助于提高传输资源的利用效率，同时还可以满足各种不同的传输需求，适应更丰富的传输场景。
另外，需要说明的是，本申请上述图5b、图6b所示的实施例中，第一节点的服务层还可为控制面中的服务发现、多域融合和5G融合等功能各分配默认的第二传输信道(图中未示出)，用于提供基础传输服务。这些第二传输信道为静态信道，会在接入层承载(例如第一承载)建立后默认激活，从而能够快速提供相应的服务，即本申请实施例中，第一承载可关联默认配置的第二传输信道和/或动态建立的第一传输信道，以适应更丰富的传输场景。
情形3：在基于第一通信技术和第二通信技术的融合通信场景下，所述第一节点的服务层支持至少两种协议栈，所述第一承载关联的至少两个传输信道(包括动态建立的所述第一传输信道、默认配置的第二传输信道)分别用于传输基于所述至少两种协议栈的数据包。
以图3所示的通信系统为例，针对智能制造、工业现场网场景等面向企业客户(To Business，TOB)业务，第一节点可通过第二节点与第二通信技术的网络(例如5G网络)建立通信连接，运营商可以通过5G核心网集中管理短距节点(包括第一节点和/或第二节点)，包括控制面管理和用户面管理两部分。
其中，在控制面管理中，短距节点与5G核心网交互的内容可以包括注册、会话建立、以及会话管理相关的QoS策略等，在该5G蜂窝网融合通信场景下，注册和QoS策略配置过程中的相关消息(例如网络连接存储(Network-attached storage，NAS)消息)可以承载在至少两种协议栈上，例如可扩展认证(Extensible Authentication Protocol，EAP)-5G协议的协议栈、用户数据报协议(User Datagram Protocol，UDP)/网际互连协议(Internet Protocol，IP)的协议栈、用户面隧道传输协议(User Plane Part of GPRS Turning Protocol，GTP-U)/流控制传输协议(Stream Control Transmission Protocol，SCTP)协议的协议栈，最后经过相应的控制面传输信道和接入层承载(即链路信道)通过空口发送。
以NAS消息为例，如图7a所示，为便于接收端接收到数据包后能够识别出NAS消息对应的协议栈，本申请实施例中，可以使同一接入层承载(例如第一承载)关联的至少两个传输信道(例如动态建立的第一传输信道、默认配置的第二传输信道)分别用于传输基于所述至少两种协议栈的数据包。例如，在动态建立第一承载关联的第一传输信道之前，第一节点的服务层可使用EAP-5G协议栈将NAS消息可以封装在EAP-5G协议的数据包中，并在第一承载关联的第二传输信道上传输至对端节点；在动态建立第一承载关联的第一传输信道之后，第一节点的服务层可使用UDP/IP协议栈将NAS消息可以封装在UDP/IP协议的数据包中，并在所述第一传输信道上传输至对端节点。相应地，对端节点的服务层接收来自第一传输信道或第二传输信道的数据包后进行解析，并将解析后的数据包递交至UDP/IP协议栈或EAP-5G协议栈进行进一步解析。
如图7b所示，该通信方法可以包括以下步骤：
S701：第一节点作为发送端，第一节点的服务层可使用EAP-5G协议栈可以将NAS消息封装在EAP-5G协议的数据包中，并在第二传输信道上传输至第二节点。相应地，第二节点的服务层接收到来自第二传输信道上的数据包后进行解析，并将解析后的数据包递交至EAP-5G协议栈进行进一步解析。
S702：第一节点通过第二节点向第二通信技术的网络发送鉴权请求。相应地，第二通信技术的网络对第一节点进行鉴权。在鉴权成功的情况下，第二通信技术的网络可通过第二节点向第一节点发送鉴权成功指示信息，第一节点的目标传输需求可以包括所述鉴权成功指示信息。
S703：第一节点可以根据所述鉴权成功指示信息，与第二节点建立第一传输信道。详细实现步骤可参见上文中图5b、图6b所示的方法步骤，在此不再赘述。
S704：第一节点作为发送端，第一节点的服务层可使用UDP/IP协议栈可以将NAS消息封装在UDP/IP协议的数据包中，并在第一传输信道上传输至第二节点。相应地，第二节点的服务层接收到来自第一传输信道上的数据包后进行解析，并将解析后的数据包递 交至UDP/IP协议栈进行进一步解析。
由此，在融合通信场景下，第一节点可以根据是否在第二通信技术的网络鉴权成功，确定是否触发动态建立第一传输信道的流程，以便在第一节点与第二节点之间动态建立能够满足融合通信场景下的传输需求的传输信道，同时配置不同协议栈数据分别通过不同的传输信道传输，既不会静态占用传输资源，有助于提高传输资源的利用效率、适应更丰富的传输场景，还可以方便对端节点准确地识别不同传输信道传输的数据包对应的协议栈。
情形4：在基于第一通信技术和第二通信技术的融合通信场景下，所述第一节点的服务层支持至少两种协议栈，基于所述至少两种协议栈的数据包可以复用同一传输信道，所述至少两种协议栈的数据包中包含指示信息，所述指示信息用于指示数据包与协议栈之间的关联关系。
仍以图3所示的通信系统和NAS消息为例，在5G蜂窝网融合通信场景下，注册和QoS策略配置过程中的NAS消息可以承载在至少两种协议栈上，例如EAP-5G协议栈、UDP/IP协议栈、GTP-U/SCTP协议栈，最后经过相应的控制面传输信道和接入层承载(即链路信道)通过空口发送。
在一种可能的设计中，如图8a所示，为便于接收端接收到数据包后能够识别出NAS消息对应的协议栈，本申请实施例中，可以使基于所述至少两种协议栈的数据包复用同一传输信道(例如第一传输信道或第二传输信道)，其中，服务层的相应功能单元(例如数据传输与适配层)可以在接收到来自上层协议栈的数据包，后，可以在该数据包中添加比特信息(即指示信息)，该指示信息可用于指示数据包与协议栈之间的关联关系，相应的帧结构如图8c所示。
其中，在发送端(例如第一节点)，服务层的数据传输与适配层接收到来自上层协议栈(例如EAP-5G协议栈或UDP/IP协议栈)的PDU后，可以该PDU作为本层负载(payload)，并在该负载之前增加包头(header)获得本层待传输的数据包，并递交至相应的传输信道传输。该包头中可以包含传输信道标识(Transmission Channel Identifier，TCID)和指示信息，该TCID用于指示数据包对应的传输信道，指示信息用于指示数据包和协议栈之间的关联关系。在接收端(例如第二节点)，服务层可以对接收到的数据包进行解析，获得包头中的指示信息，从而确定后续路由方向，即将解析数据包获得的负载递交给EAP-5G协议栈还是UDP/IP协议栈。
在另一种可能的设计中，如图8b所示，为尽可能地减少对服务层以及现有协议的改动，本申请实施例中，可以在服务层中，在所述至少两种协议栈的下层、所述数据传输与适配层的上层新增第一逻辑实体，该第一逻辑实体可以接收来自上层协议栈的数据包，并在该数据包中增加指示信息，该指示信息用于指示数据包与协议栈之间的关联关系，相应的帧结构可以为图8c中未包含传输信道标识的部分，本申请实施例对该指示信息的添加方式以及相应的数据包帧结构不做限定。
需要说明的是，对端节点(例如第二节点)采用同样的方式，例如通过数据传输与适配层或者新增的第二逻辑实体(与第一逻辑实体对应)，对下层递交的数据包进行解析，以通过解析得到的指示信息，获知数据包需要递交至上层的哪一个协议栈，在此不再赘述。由此，上述实施例中，在融合通信场景中，第一节点支持至少两种协议栈的情况下，第一节点可以通过在数据包包头中增加指示信息，使得所述至少两种协议栈可以复用同一传输信道，以减少对传输资源的占用。同时，通过所述指示信息来指示数据包与协议栈的关联 关系，使得对端节点在对接收到所述数据包并进行解析时，能够准确地识别出数据包对应的协议栈。

在一种可选的设计中，装置900可以用于执行第二节点所执行的通信方法，例如通信单元902，用于接收来自第一节点的第一请求消息，所述第一请求消息用于请求建立第一传输信道，所述第一传输信道用于与所述第二节点通信，所述第一传输信道关联所述第一节点的目标传输需求；以及，向所述第一节点发送第一响应消息，所述第一响应消息用于确认建立所述第一传输信道。具体实现方式，请参考图1至图8c所示实施例中的详细描述，这里不再赘述。
