作为示例而非限定，图中示出的通信系统100包括电子设备101、102、103、104、105、106、107。电子设备101至107中的任意一个电子设备可以为上述提到的任意一种形式的电子设备。可以理解的是，通信系统100中所包括的电子设备的数量可以是更多或更少，本申请实施例对此并不限定，但至少包括两个电子设备。需要说明的是，图1所示的通信系统100仅为示意性说明，该通信系统中还可以包括其他设备，例如路由器或基站等设备，本申请实施例对此不作限定。
电子设备之间可以通过无线短距通信技术进行通信，实现信息共享和业务的无线传输。随着新需求的提出和新技术的发展，无线短距通信技术也在不断发展。为解决面向全行业互联网场景的需求，星闪联盟(sparklink alliance)成立并致力于推动新一代无线短距通信技术创新和产业生态，以承载智能汽车、智能家居、智能终端和智能制造等场景应用并满足极致性能需求。本申请实施例中所涉及的电子设备可以基于星闪联盟所设计的新一代无线短距通信技术进行通信。
针对上述场景，为支撑新一代无线短距通信技术并实现短距业务的完整流程，需要建立全新的协议框架。图2示出了本申请实施例提供的协议框架示意图。该协议框架可应用于任何可实现短距离通信的电子设备中，例如图1所示的通信系统100中的任意一个电子设备。如图2所示，协议框架200自下而上包括接入层210、基础服务层220和基础应用层230。
接入层210，主要负责底层逻辑链路的处理，例如逻辑链路的建立、重配置、删除等，以承接基础服务层220的业务需求(如可靠数据、实时数据等)，其中逻辑链路用于在两个电子设备之间传输业务。接入层210包括多种接入技术，包括但不限于星闪基础(sparklink basic，SLB)短距无线通信系统的接入技术、星闪低功耗(sparklink low energy，SLE)短距无线通信系统的接入技术以及其他的接入技术，例如蓝牙低功耗(bluetooh low energy，BLE)技术、未来其他的星闪联盟接入技术等等，本申请实施例中仅以SLB和 SLE接入技术为例对接入层210的架构作简要介绍。
如图2所示，接入层210进一步可以包括数据链路层和物理层。数据链路层用于实现资源管理、访问控制、数据分段、级联、重排序等功能，以保障数据的可靠传递。物理层利用传输介质为数据链路层提供物理连接，以实现比特流的透明传输。在一些实施例中，数据链路层可以包括链路控制层和媒体接入层。链路控制层主要是基于节点间建立的链路，在控制链路上交互链路控制协议(link control protocol，LCP)，起到物理/逻辑链路管理、设备行为的控制等功能。媒体接入层负责进行无线资源分配，并为链路控制层提供数据传输服务。本申请实施例中，SLB接入技术主要负责大宽带、高速率、高功耗业务(例如视频播放业务)的传输，SLE接入技术主要负责小带宽、低速率、低功耗业务(例如音频播放业务)的传输。
对于一个支持两种接入技术如SLB和SLE的电子设备来说，其接入层可以通过不同的模块分别实现SLB接入和SLE接入。本申请实施例中，上层的一个业务，可以通过多个接入技术进行动态传输，提高业务传输的灵活性。
可以理解的是，上述介绍的两种星闪联盟接入技术的名称仅仅是示例性的，不应理解为是对本申请实施例的限定，在其他实施例中或者在未来的架构中，SLB和SLE还可以使用其他的名称。
基础服务层220，主要负责传输通道的创建、添加、删除、释放等，以及逻辑链路的控制(例如接入技术的选择)，以承接基础应用层230的业务需求(例如流量、速率、音质、分辨率)。其设计目标是可以兼容多种接入层技术，例如兼容上述介绍的SLB、SLE接入技术，并保留兼容未来更多接入技术的能力。
基础服务层220可以包括多个实现上述设计目标的模块或功能单元，包括但不限于设备发现模块、服务管理模块、通道管理模块、服务质量(quality of service，QoS)管理模块、安全管理模块、测量管理模块、多域协调模块、5G融合模块等。其中，设备发现模块用于在没有与设备进行连接的时候发现设备。服务管理模块用于对设备上的服务进行发现与操作。通道管理模块用于对传输通道进行管理，包括创建/添加/删除/释放，在后文中会进行详细介绍该模块的功能，在此暂不详述。QoS管理模块用于对传输的QoS进行管理与协商。安全管理模块负责基础服务层的安全连接。测量管理模块用于配置底层的测量与调度，用以进行功率控制等。多域协调模块在存在多个域(子网)的场景下，实现域之间的信息交互，实现多域间的干扰避免，负载平衡。5G融合模块用于建立具有蜂窝5G远端管理能力的通道，通过鉴权和认证机制，实现具有蜂窝5G远端控制功能的设备。
基础服务层220的传输可以分为控制面的传输和业务面的传输，相应地，基础服务层220的传输通道可以包括控制通道和业务通道，其中控制通道用于传输控制面的数据，业务通道用于传输业务面的数据。本申请以下实施例将对业务通道的相关流程进行详细描述。
基础应用层230，主要负责承接上层应用(application，APP)的不同业务需求，并且完成数据到基础服务层220的路由。根据业务的不同分类，基础应用层230可以包括多个不同的业务功能集合(也可称为业务模块或业务框架)，例如音视频框架、数据框架等等。不同业务功能集合，包含了对业务的分类数据处理。
示例性的，如图2所示，应用层230可以包括通用感知框架、通用设备管理框架、通用音视频框架、通用数据框架等。其中，通用感知框架包含了对感知数据的处理；通用设 备管理框架包含了对设备管理数据的处理；通用音视频框架包含了对音视频诗句的处理，例如编解码处理；通用数据框架包含了对文件数据的处理，如加密压缩等。不同的业务功能集合可以通过业务标识(business identification，BID)区分。
本申请实施例中，基础服务层220和基础应用层230可以统称为上层协议或Host协议。Host协议能够适配底层的接入层210，支撑不同业务的需求，具体地，Host协议能够提供给业务模块发起业务的请求，并对业务数据进行传输和控制。
本申请实施例中，图1所示的电子设备可以支持至少一种接入技术，例如支持图2所示的SLB接入技术和SLE接入技术中的至少一种。无论接入层支持何种接入技术，上层均可以采用统一的Host协议，也即上层可以兼容多种接入技术。
为便于理解本申请，下面对本申请中涉及的相关技术术语进行说明。
端口(port)，是基础应用层的通道，对下可以实现多个端口映射到同一个传输通道。
传输通道(transmission channel，TC)，是基础服务层的通道，对上可承接多个端口(port)映射，对下可以实现多个传输通道映射到同一逻辑通道。
逻辑通道(logical channel，LC)，是接入层的通道，对上可承接多个传输通道映射。在一些实施例中，也可以称为逻辑链路。一个逻辑通道对应一种接入技术。
具体地，参考图2所示，基础应用层230具有端口的概念，基础服务层220具有传输通道的概念，接入层210具有逻辑通道的概念。换言之，端口是基础应用层230的通道，传输通道是基础服务层220的通道，逻辑通道是接入层210的通道。多个端口可以映射到同一个传输通道，即端口与传输通道具有映射关系；多个传输通道可以映射到同一个逻辑通道，即传输通道与逻辑通道具有映射关系。逻辑通道是上层的基础服务层中的传输通道的建立的基础，在逻辑通道建立成功后，基础服务层的传输通道才可用。两个电子设备通信时，业务数据可以通过一个电子设备的端口-传输通道-逻辑通道路径，发送给另一个电子设备。
为了区分逻辑通道，定义了逻辑通道标识(logical channel identification，LCID)，用于唯一标识逻辑通道。
传输通道组(transmission channel group)，包括多条传输通道。该多条传输通道可共同用于传输从同一个端口下发的数据。也就是说，一个端口下发的数据(如数据流，该数据流可以包括多个数据包)只通过一个传输通道组传输。具体地，基础应用层将某个端口的数据传输到基础服务层之后，由基础服务层在对应的传输通道组中选择一个或多个传输通道传输这些数据包。不同的传输通道可以传输相同的数据，也可以分别传输不同的数据。例如在传输可靠业务时，传输通道组内的传输通道可以传输相同的数据包，即数据包在传输通道组内进行冗余传输；在传输大流量业务时，传输通道组内的传输通道可以分别传输不同的数据包。本申请实施例中，传输通道可以认为是传输通道组中的子通道。
为了区分传输通道，定义了传输通道标识(transmission channel identification，TCID)，用于唯一标识传输通道。在一些实施例中，传输通道标识可以包括多个比特(bit)，其中部分比特用于标识该传输通道所属的传输通道组的编号，即组编号(group identification，GroupID)，部分比特用于标识该传输通道在传输通道组内的编号，即组内编号(local identification，LocalID)。例如，传输通道标识可以包括16bits，其中高13bits用于标识组编号GoupID，低3bits用于标识组内编号LocalID。
上文提到端口和传输通道具有映射关系，实际上，上层只关心传输通道组，而不关心子通道，因此对于基础应用层来说，其获取和维护的是端口与传输通道组之间的映射关系。这样基础应用层向基础服务层传输数据时，基础服务层可以根据端口与传输通道组的映射关系，在传输通道组内选择一个或多个传输通道进行传输。也就是说，对于一个子通道来说，基础服务层生成的是传输通道标识TCID。而传输通道向上层展示时，展示传输通道组即可。
因此，基础服务层向基础应用层传递传输通道组这一信息可以有多种方式，只要基础应用层能够获取到端口与传输通道组的映射关系即可。
示例性的，基础服务层向基础应用层展示传输通道时，可以传递完整的传输通道标识，也可以传递组编号GroupID不变而组内编号LocalID为0的标识，还可以传递传输通道组的标识(即组编号)。为便于理解，下面以传输通道标识包括16bits为例进行说明。也就是说，传输通道的相关信息向上层传递时，可以有以下几种情况：
1)基础服务层向上层传递传输通道标识TCID，示例如下：
13bits 3bits
GroupID LocalID
相应地，上层即基础应用层接收到该传输通道标识TCID后，可以只解析高13bits，从而获得传输通道组的信息。或者基础应用层将16bits的传输通道标识解析后，提取高13bits的信息，也可以获得传输通道组的信息。
2)基础服务层向上层传递组编号GroupID不变而组内编号LocalID为0的标识，为方便描述，本申请实施例称为传输通道映射标识(maptransmission channel identification，MapTCID)，示例如下：
13bits 3bits
GroupID 0b000
由于MapTCID中的有效信息为高13bits的GroupID，可以认为当基础应用层有数据需要传输时，基础服务层可以从GroupID所标识的传输通道组内选择传输通道进行传输。基础应用层关心的是在哪个传输通道组传输数据，而不关心具体使用传输通道组内的哪个传输通道进行传输。
3)基础服务层向上层传递传输通道组标识，示例如下：
13bits
GroupID
也就是说，基础应用层可以只用13bits传递传输通道组的标识GroupID，使得基础应用层获得传输通道组的信息。
需要说明的是，上述用于表示传输通道标识的比特数以及传输通道向上层展示的方式仅仅是示例性的，在其他实施例中，也可以采用其他方式实现，例如将同一传输通道组内的传输通道标识均与另一标识相映射，然后基础服务层向上层传递该另一标识等，本申请对此不作限定。
上面介绍了各个层用于路由数据的通道，下面结合图2简要描述数据的传输路径。参 考图2所示，当有业务数据需要传输时，基础应用层230通过数据流(flow)将数据由端口传输到基础服务层220，基础服务层220选择一条或多条传输通道进行传输。由于传输通道与逻辑通道具有映射关系，相应地，接入层接收到数据后使用对应的逻辑通道继续传输。
示例性的，基础服务层220可以包括传输通道TCID1-TCIDx，基础服务层220可以选择TCID1传输通用感知框架发送的Qos流1，选择TCID2传输通用设备管理框架发送的Qos流2，选择TCID3传输通用音视频框架发送的Qos流3，选择TCIDx传输通用数据框架发送的Qos流4，等等。到接入层210时，TCID1传输的数据通过支持SLB的一个逻辑通道传输，TCID2传输的数据通过支持SLB的一个逻辑通道传输，TCID3传输的数据通过支持SLE的一个逻辑通道传输，TCIDx传输的数据通过支持SLE的一个逻辑通道传输。可以理解的是，图中示出的数据流和传输通道的对应关系以及传输通道和逻辑通道的对应关系仅仅是示例性的，不应理解为是对本申请的限定。
传输通道TCID1-TCIDx中的任意一个传输通道可以属于某个传输通道组，任意一个传输通道向上层展示时，可以展示为TCID、MapTCID或GroupID。
传输通道可以包括业务通道和控制通道，其中业务通道用于传输业务面的数据，控制通道用于传输控制面的数据。控制通道的建立是电子设备间建立业务通道的基础，因此本申请实施例所涉及的业务通道的相关流程，是在控制通道建立的基础上执行的，关于控制通道的建立流程，本申请实施例不再进行过多描述。
业务通道可以包括单播业务通道、组播业务通道和广播业务通道。单播业务通道是用于传输单播业务的业务通道，可以实现点对点传输。组播业务通道是用于传输组播业务的业务通道，可以实现点对组传输，其底层有反馈(ack)，具有一定底层可靠性。广播业务通道是用于传输广播业务的业务通道，可以实现无连接传输，其底层无反馈(ack)，需要通过多次发送保障可靠性。
单播业务通道包括缺省业务通道和非缺省业务通道，其中缺省业务通道在控制通道建立完成时自动建立，非缺省业务通道在有业务需求时根据需求建立。本申请实施例主要对非缺省业务通道的相关流程进行详细介绍。
本申请实施例中，非缺省业务通道的相关流程主要包括：创建非缺省业务通道的流程、添加非缺省业务子通道的流程、删除非缺省业务子通道的流程、释放非缺省业务通道的流程。
需要说明的是，本申请实施例中主要针对业务通道中的非缺省业务通道进行描述，因此以下实施例中涉及到“传输通道”的描述时，可以狭义理解为是业务通道，涉及到“传输通道组”的描述时，可以狭义理解为是业务通道组。业务通道仍可以使用上文所描述的TCID来进行标识，即以下实施例中涉及到“TCID”的描述时，可以狭义理解为是业务通道的标识。在其他一些实施例中，用于标识业务通道的TCID还可以称为“业务通道标识”或者其他的名称，本申请实施例对此不作限定。
本申请实施例中，创建非缺省业务通道的流程，可以认为是创建新的传输通道组的流程。添加非缺省业务子通道的流程，可以认为是在已有的传输通道组的基础上，在该传输通道组中增加新的传输通道的流程。删除非缺省业务子通道的流程，可以认为是在已有的传输通道组中，删除传输通道的流程。释放非缺省业务通道的流程，可以认为是释放已有 的传输通道组的流程，也即删除已有的传输通道组中的全部传输通道的流程。以下，以第一电子设备和第二电子设备为例，结合图2所示的协议架构，通过第一电子设备和第二电子设备之间以及各个电子设备内部各个层之间的交互，对上述各个流程做说明。其中，第一电子设备和第二电子设备中的基础服务层涉及通道管理模块。
图3示出了本申请一个实施例提供的创建非缺省业务通道的流程示意图。在该流程的实现过程中，涉及第一电子设备和第二电子设备，两个电子设备可以均具有如图2所示的基础应用层230、基础服务层220以及接入层210。图3示出的创建非缺省业务通道的流程300包括步骤S301至步骤S313，下面结合图3对各个步骤进行详细描述。
当第一电子设备和第二电子设备需要进行无线业务时，例如用户使用第一电子设备(如手机)与第二电子设备(如无线耳机)传输音乐进行播放时，第一电子设备与第二电子设备之间可以进行如下流程。
在步骤S301，第一电子设备的基础应用层和第二电子设备的基础应用层进行端口(port)协商。
在该步骤中，协商过程所涉及的数据可以通过已经建立的缺省业务通道传输。缺省业务通道是在控制通道建立完成之后自动建立的，用于传输服务管理数据。因此，在非缺省业务通道创建成功之前，第一电子设备和第二电子设备之间需要交互的服务管理数据均可以通过缺省业务通道进行传输。
在一些实施例中，在步骤S301中，第一电子设备的基础应用层和第二电子设备的基础应用层还可以进行业务协商和应用服务质量(quality of service，QoS)协商等。例如，第一电子设备和第二电子设备之间的业务协商、QoS协商和端口协商等均可以通过基础应用层中的业务框架使用服务管理模块提供的数据模板在缺省业务通道上进行统一传输。本申请实施例主要关注第一电子设备和第二电子设备进行端口协商的结果，因此对于其他协商过程，如业务协商、QoS协商等，在此不作过多描述。
示例性的，第一电子设备和第二电子设备协商的结果可以是第一电子设备使用第一端口(port1)映射，第二电子设备使用第二端口(port2)映射。相应地，第一端口port1和第二端口port2即具有映射关系，第一电子设备的基础应用层和第二电子设备的基础应用层需维护第一端口和第二端口之间的映射关系。
本申请实施例中，第一电子设备为发起业务请求的一端，在一些实施例中也可以称为本端。第二电子设备为接收数据的一端，在一些实施例中也可以称为对端。
在步骤S302，第一电子设备的基础应用层向基础服务层(具体可以为通道管理模块)申请业务通道。
在该步骤中，第一电子设备的基础应用层为第一端口和第二端口向通道管理模块申请业务通道。
具体地，在步骤S302中，第一电子设备的基础应用层可以向通道管理模块发送信息#31，该信息#31用于为第一端口和第二端口申请业务通道。
该信息#31可以包括业务通道类型指示信息、端口信息、服务质量指示(quality of service identifier，QI)等。其中，业务通道类型指示信息用于指示所申请的业务通道类型，其中业务通道类型可以包括单播业务通道、组播业务通道和广播业务通道。若业务通道类型指示信息指示所申请的业务通道为单播业务通道时，该单播业务通道指的是非缺省业务 通道。端口信息用于指示与业务通道映射的端口，即步骤S301协商出来的端口。在本申请实施例中，该端口信息包括第一端口和第二端口，其中第一端口用于与第一电子设备侧的业务通道映射(可以理解的是，实际是与业务通道所属的业务通道组映射)，第二端口用于与第二电子设备侧的业务通道映射(可以理解的是，实际是与业务通道所属的业务通道组映射)。QI用于指示业务对业务通道的需求，例如传输速率、时延、丢包率、通信周期、最大包大小等。
在一些实施例中，信息#31还可以包括附加参数，例如传输模式指示信息、是否专载指示信息等。传输模式指示信息用于指示数据的传输模式，其中传输模式可以包括基础模式、透传模式、普通模式、流控模式、流模式、重传模式等。
基础模式是默认的传输模式。采用基础模式传输时，不分包，不聚包，不重传，不流控。透传模式，是指业务通道与逻辑链路一一映射。采用透传模式传输时，不分包，不聚包，不加传输与控制模块包头。采用普通模式传输时，可以分包，可以聚包，不重传，不流控。采用流控模式传输时，数据包被编号，发送的数据需要有对端ack，可以提前滑窗，数据不被重传。当定时器超时，未收到对端ack的数据直接被丢弃，被丢弃的数据被检测到并上报。采用流模式传输时，需单向实时同步数据，发送端有一个刷新超时(flush timout)值来控制没有发送的包的刷新。重传模式中具有可靠的传输机制，数据在传输控制层有重传，当收到对端回复nack或者定时器超时，会进行重传。重传包不会再进行组包聚包等处理，而是对整个包进行重传。当重传达到最大次数时，对应的业务通道需要断开，并报告给上层。
附加参数中的是否专载指示信息用于指示业务通道是否专用于传输某个业务的数据。本申请实施例中，通道管理模块若接收到专载指示，会新分配一个业务通道给第一端口，而不会复用已有的业务通道，并且新分配的业务通道在之后的其他流程中不会被复用。
本申请实施例中，若信息#31中包括附加参数，则通道管理模块可以按照信息#31中的附加参数设置相关参数。若信息#31中不包括附加参数，则通道管理模块可以自行设置相关参数，或者按照预设规则设置相关参数，本申请实施例对此不作限定。
在步骤S303，第一电子设备的基础服务层(具体为通道管理模块)判断是否创建非缺省业务通道。
也即，第一电子设备的基础服务层判断是否创建新的业务通道组。换句话说，在该步骤中，第一电子设备的通道管理模块判断将第一端口映射到已有的业务通道组，还是创建新的业务通道组后将第一端口映射到新的业务通道组。
通道管理模块在判断是否要创建非缺省业务通道时，可以有多种实现方式。
在一个示例中，通道管理模块可以根据信息#31中的QI确定是否创建非缺省业务通道。例如相同的QI可以复用同一个业务通道，即若信息#31所包括的QI与已经传输的某业务的QI相同，则可以复用已有的业务通道，而不创建新的非缺省业务通道。
在另一个示例中，通道管理模块可以根据信息#31中的传输模式指示信息确定是否创建非缺省业务通道。例如若上层指示业务数据的传输模式为透传，则创建新的非缺省业务通道，而不复用已有的业务通道。
在又一个示例中，通道管理模块可以根据信息#31中的是否专载指示信息确定是否创建非缺省业务通道。例如是否专载指示信息指示业务通道专用于传输新的业务数据，则创 建非缺省业务通道。
也就是说，通道管理模块可以根据信息#31判断是否创建非缺省业务通道。在一些实施例中，如果上层发送的信息#31中没有指示通道管理模块创建新的业务通道组的话，通道管理模块可以根据自身算法(例如预设规则)进行判断。例如预设上层没有指示是否创建的情况下，默认不创建或默认创建非缺省业务通道。
在其他示例中，通道管理模块还可以根据其他信息，例如业务类型、底层通道能力、业务传输需求等判断是否创建非缺省业务通道。在具体实现中，可以依据不同厂商的不同算法执行步骤S303，在此不再过多描述。
在该步骤S303中，若通道管理模块确定不创建非缺省业务通道，则可以将第一端口映射到已有的业务通道(即已创建的业务通道)上，以使用已有的业务通道传输新的业务数据。然后通道管理模块执行步骤S313，通知第一电子设备的基础应用层业务通道申请成功，并将第一端口port1和第一映射标识发送给基础应用层。
可以理解的是，这里的第一映射标识即基础服务层向上层传递的用于指示业务通道所属的组的标识。例如，第一映射标识可以是所复用的业务通道的标识TCID，可以是所复用的业务通道所属的业务通道组的标识GroupID，也可以是与所复用的业务通道对应的传输通道映射标识Map TCID，本申请实施例对此不作限定。相应地，第一电子设备的基础应用层需维护第一端口与第一映射标识的映射关系，即第一端口与第一映射标识所指示的业务通道组的映射关系。
在该步骤S303中，若通道管理模块确定创建非缺省业务通道，则生成新的业务通道的标识TCID-s。
可以理解的是，这里的标识TCID-s是新创建的业务通道的标识。在实际应用中，用于传输数据的业务通道在第一电子设备侧和第二电子设备侧可以具有不同的标识，为方便描述，本申请实施例中将第一电子设备侧(即本端)的业务通道的标识表示为TCID-s，将第二电子设备侧(即对端)的业务通道的标识表示为TCID-d。在业务通道建立完成后，第一电子设备和第二电子设备均可以维护本端业务通道的标识TCID-s和对端业务通道的标识TCID-d。
在步骤S304，第一电子设备的基础服务层(具体为通道管理模块)与第二电子设备的基础服务层(具体为通道管理模块)进行通道参数协商。
具体地，在该步骤中，第一电子设备的通道管理模块可以向第二电子设备的通道管理模块发送通道参数协商请求。相应地，第二电子设备的通道管理模块可以向第一电子设备的通道管理模块发送通道参数协商响应。通过该交互过程进行通道参数的协商。
在一些实施例中，两个电子设备的通道管理模块所协商的通道参数可以包括传输窗口滑窗大小(如以TxWindow表示)、刷新定时器(如以Flushtimer表示)、最大传输次数(如以maxRetxThreshold表示)、重传定时器(如以RetransmissionTimer表示)等。本申请实施例中，该步骤中所协商的通道参数与业务的传输模式有关，例如传输窗口滑窗大小是流控模式与重传模式需要协商的参数，刷新定时器是流模式需要协商的参数，最大传输次数是重传模式需要协商的参数，重传定时器是流控模式与重传模式需要协商的参数。
在协商过程中，第一电子设备和第二电子设备需要交互的信息可以通过控制通道传输。
步骤S304为可选步骤。在一些实施例中，第一电子设备和第二电子设备也可以不进 行通道参数协商，由通道管理模块可以自行设置通道参数，或者按照预设规则设置通道参数，在此不作过多描述。
在步骤S305，第一电子设备的基础服务层向接入层申请逻辑通道。
具体地，在步骤S305中，第一电子设备的基础服务层可以向接入层发送信息#32，该信息#32用于向接入层申请逻辑通道。该信息#31可以包括创建TCID-s的业务需求。
该信息#32可以包括本端业务通道的标识TCID-s、逻辑通道类型指示信息、服务质量QoS等。其中，本端业务通道的标识TCID-s用于接入层建立业务通道和逻辑通道的映射关系。逻辑通道类型指示信息用于指示逻辑通道的类型。QoS用于接入层选择逻辑通道或对逻辑通道的相关参数进行配置等。
在实际应用中，逻辑通道类型可以依据不同的接入技术具有不同的划分方式，例如对于SLE接入技术，逻辑通道类型可以包括异步逻辑通道、同步逻辑通道、单向逻辑通道等；对于SLB接入技术，逻辑通道类型可以包括非确认模式(unacknowledgedmode，UM)逻辑通道、确认模式(acknowledgedmode，AM)逻辑通道、透传模式(transparent mode，TM)逻辑通道等。采用AM模式逻辑通道传输时，需添加链路控制层包头信息，链路控制层进行状态报告。采用UM模式逻辑通道传输时，需添加链路控制层包头信息，链路控制层不进行状态报告。采用TM模式逻辑通道传输时，不添加链路控制层包头信息，链路控制层不进行状态报告。第一电子设备的基础服务层(具体为通道管理模块)可以根据业务需求和/或底层能力选择逻辑通道类型，并通过逻辑通道类型指示信息指示给接入层。例如对于支付应用业务，通道管理模块可以选择可靠的、保密性高的逻辑通道类型；对于视频应用业务，通道管理模块可以选择低时延的逻辑通道类型。
需要说明的是，由于一种逻辑通道对应一种接入技术，这里基础服务层选择逻辑通道类型的过程，可以认为是基础服务层选择接入技术的过程，基础应用层并不感知底层使用的哪种接入技术。
还需要说明的是，信息#32中的QoS和信息#31中的QI均用于指示服务质量，但二者的格式和所包括的信息可以不同。具体地，基础服务层在接收到基础应用层下发的业务需求后，会对信息进行抽象和处理，生成接入层能够解析的业务需求，并下发给接入层。
在一些实施例中，信息#32还可以包括附加参数，例如是否专载指示信息。是否专载指示信息用于指示业务通道是否专用于传输对应的业务数据。这里，接入层可以根据是否专载指示信息选择逻辑通道或对逻辑通道的相关参数进行配置。
在步骤S306，第一电子设备的接入层将业务通道TCID-s映射到逻辑通道LCID。即，建立业务通道TCID-s与逻辑通道LCID的映射关系。
具体地，在该步骤中，第一电子设备的接入层可以根据传输情况从以下几种方案中选择一种来建立底层逻辑链路：
方案1(case#1)：将TCID-s映射到已有的逻辑通道LCID。即建立TCID-s与已建立的某个逻辑通道之间的映射关系。
例如当某个已有的逻辑通道能够支持现有业务和新增业务时，可以将新建的业务通道TCID-s映射到该已有的逻辑通道上，从而建立TCID-s与LCID的映射关系。
方案2(case#2)：重配置已有的逻辑通道，并将TCID-s映射到重配后的逻辑通道LCID。
例如，接入层根据传输情况确定某个已有的逻辑通道的相关参数不能满足基础服务层下发的业务需求，则可以将该已有的逻辑通道的相关参数进行重配置，再将新建的业务通道TCID-s映射到重配的逻辑通道上，从而建立TCID-s与LCID的映射关系。
方案3(case#3)：建立新的逻辑通道，并将TCID-s映射到新的逻辑通道LCID。
例如在已有的逻辑通道全部用于传输异步数据的情况下，如果基础应用层发起的业务请求是传输同步数据，则接入层可以新建逻辑通道用于传输同步数据。再将新建的业务通道TCID-s映射到新建的逻辑通道上，从而建立TCID-s与LCID的映射关系。
需要说明的是，上述所列举的几种方案以及适用场景仅仅是示例性的，在其他实施例中，接入层在建立底层逻辑链路时所选择的方式可以有其他方式，上述几种方案所适用的场景还有其他场景，在此不再一一描述。
步骤S306完成后即建立了业务通道和逻辑通道的映射关系。
在步骤S307，第一电子设备的接入层向基础服务层(具体为通道管理模块)反馈逻辑通道申请成功。
具体地，在该步骤中，第一电子设备的接入层可以向通道管理模块发送信息#33，该信息#33用于指示逻辑通道申请成功，也就是指示业务通道和逻辑通道的映射关系建立。例如，信息#33可以包括创建的业务通道的标识TCID-s和逻辑通道的标识LCID。换言之，接入层通过信息#33将TCID-s和LCID的映射关系返回给基础服务层。
第一电子设备的通道管理模块接收到业务通道和逻辑通道的映射关系后，认为底层逻辑链路已经可以进行传输。
在步骤S308，第一电子设备的基础服务层向第二电子设备的基础服务层发送创建传输通道请求，该创建传输通道请求用于向第二电子设备通知第一电子设备侧的业务通道和逻辑通道的映射关系建立。
具体地，在该步骤中，第一电子设备的基础服务层可以向第二电子设备的基础服务层发送信息#34，该信息#34用于指示第一电子设备已建立本端业务通道和逻辑通道的映射关系，也用于指示第二电子设备建立对端业务通道和逻辑通道的映射关系。
该信息#34可以包括第二端口port2、本端业务通道的标识TCID-s和逻辑通道的标识LCID。
在步骤S309，第二电子设备的基础服务层生成对端业务通道的标识TCID-d。
步骤S309完成后，第二电子设备可以认为两个电子设备的基础服务层已经建立了TCID-s和TCID-d的连接，也即可以确定TCID-s和TCID-d的映射关系。第二电子设备可以保存本端业务通道的标识TCID-s和逻辑通道标识LCID，并维护TCID-s与LCID的映射关系以及TCID-s和TCID-d的对应关系等。相应地，第二电子设备可以初始化对端业务通道所属的业务通道组内的通道数为1。
本申请实施例中，逻辑通道的标识在第一电子设备和第二电子设备上相同，因此第二电子设备接收到第一电子设备发送的LCID后，即可以建立业务通道TCID-d与LCID的映射关系。
在步骤S310，第二电子设备的基础服务层(具体为通道管理模块)将对端的端口信息与业务通道的映射信息发送给第二电子设备的基础应用层，以进行端口映射。
具体地，在该步骤中，第二电子设备的通道管理模块可以向基础应用层发送信息#35， 该信息#35用于指示业务通道组与端口的映射关系，即业务通道TCID-d所属的业务通道组与第二端口的映射关系。
该信息#35可以包括第二端口port2和第二映射标识，以用于建立第二端口与对端业务通道组的映射关系。这里的第二映射标识即第二电子设备的基础服务层向上层传递的用于指示业务通道所属的组的标识。例如，第二映射标识可以是对端业务通道的标识TCID-d，可以是对端业务通道所属的业务通道组的标识GroupID，也可以是与对端业务通道TCID-d对应的传输通道映射标识Map TCID，本申请实施例对此不作限定。相应地，第二电子设备的基础应用层需维护第二端口与第二映射标识的映射关系，即第二端口与第二映射标识所指示的业务通道组的映射关系。
在步骤S311，第二电子设备的基础应用层向基础服务层反馈端口映射成功。
在步骤S312，第二电子设备的基础服务层向第一电子设备的基础服务层发送创建传输通道响应，该创建传输通道响应用于向第一电子设备通知第二电子设备侧的业务通道和逻辑通道的映射关系。
具体地，在该步骤中，第二电子设备的基础服务层可以向第一电子设备的基础服务层发送信息#36，该信息#36用于指示第二电子设备已建立对端业务通道和逻辑通道的映射关系。
该信息#36可以包括对端业务通道的标识TCID-d和逻辑通道的标识LCID。
需要说明的是，步骤S308和步骤S312中，第一电子设备的基础服务层与第二电子设备的基础服务层交互的数据可以通过控制通道传输。
步骤S312完成后，第一电子设备可以认为两个电子设备的基础服务层已经建立了TCID-s和TCID-d的连接，即可以确定TCID-s和TCID-d的映射关系。第一电子设备可以保存对端业务通道的标识TCID-d和逻辑通道标识LCID，并维护TCID-d与LCID的映射关系以及TCID-s和TCID-d的对应关系等。相应地，第一电子设备可以初始化本端业务通道所属的业务通道组内的通道数为1。
在步骤S313，第一电子设备的基础服务层(具体为通道管理模块)通知基础应用层业务通道申请成功。
具体地，在该步骤中，第一电子设备的通道管理模块可以向基础应用层发送信息#37，该信息#37用于指示本端业务通道TCID-s所属的业务通道组与端口的映射关系。
该信息#37可以包括第一端口port1和第一映射标识，以用于建立第一端口与本端业务通道组的映射关系。这里的第一映射标识即第一电子设备的基础服务层向上层传递的用于指示业务通道所属的组的标识。例如，第一映射标识可以是本端业务通道的标识TCID-s，可以是本端业务通道所属的业务通道组的标识GroupID，也可以是与本端业务通道TCID-s对应的传输通道映射标识Map TCID，本申请实施例对此不作限定。相应地，第一电子设备的基础应用层需维护第一端口与第一映射标识的映射关系，即第一端口与第一映射标识所指示的业务通道组的映射关系。
需要说明的是，非缺省业务通道创建完成后，业务通道组内的通道数初始化为1，但实际的业务数据不一定在该创建的非缺省业务通道上传输，可以在业务通道组内的任意通道上传输。这就涉及到添加非缺省业务子通道的流程，以下将结合其他附图进行详细介绍，在此暂不详述。
本申请实施例中，第一电子设备和第二电子设备的接入层可以均支持多种接入技术，例如SLB接入技术和SLE接入技术。当第一电子设备与第二电子设备需要进行无线业务时，用户无需选择或指定在哪个接入技术上进行业务传输，而是在基础应用层下发业务需求后，由基础服务层根据业务需求自行选择底层接入技术，并建立业务通道进行传输。
本申请实施例中，第一电子设备确定了第一端口port1与本端业务通道TCID-s所属的业务通道组的映射关系以及本端业务通道TCID-s与逻辑通道LCID的映射关系，第二电子设备确定了第二端口port2与对端业务通道TCID-d所属的业务通道组的映射关系以及对端业务通道TCID-d与逻辑通道LCID的映射关系，且相互通知了对方。因此，通过图3所示的流程创建的非缺省业务通道为双向业务通道，即第一电子设备可以利用创建的非缺省业务通道向第二电子设备传输业务，第二电子设备也可以利用创建的非缺省业务通道向第一电子设备传输业务，其中业务数据的传输路径可以为第一端口
Figure PCTCN2022107612-appb-000001
第二端口port2。可以理解，通过图3所示的流程300创建的双向业务通道支持双向传输，也可以兼容单向传输。
图4示出了本申请另一个实施例提供的创建非缺省业务通道的流程示意图。在该流程的实现过程中，涉及第一电子设备和第二电子设备，两个电子设备可以均具有如图2所示的基础应用层230、基础服务层220以及接入层210。图4示出的创建非缺省业务通道的流程400与图3示出的创建非缺省业务通道的流程300类似，不同的是，流程400中创建的非缺省业务通道为单向业务通道，交互过程中所携带的参数和数据路由有所区别。下面主要对流程400与流程300之间的不同之处进行详细描述，其他未详尽描述的部分可以参考流程300中的相应描述。
如图4所示，创建非缺省业务通道的流程400包括步骤S401至步骤S411。
在步骤S401，第一电子设备的基础应用层和第二电子设备的基础应用层进行端口(port)协商。
该协商过程所涉及的数据可以通过已经建立的缺省业务通道传输。
在一些实施例中，在步骤S401中，第一电子设备的基础应用层和第二电子设备的基础应用层还可以进行业务协商和应用服务质量(quality of service，QoS)协商等，在此不作过多描述。
示例性的，第一电子设备和第二电子设备协商的结果可以是第一电子设备使用第一端口(port1)映射，第二电子设备使用第二端口(port2)映射。
在步骤S402，第一电子设备的基础应用层向基础服务层(具体可以为通道管理模块)申请业务通道。
具体地，第一电子设备的基础应用层可以向通道管理模块发送信息#41，该信息#41用于为第一端口申请传输业务通道。
该信息#41可以包括业务通道类型指示信息、第一端口、QI等。其中，业务通道类型指示信息用于指示所申请的业务通道类型。第一端口用于与第一电子设备侧的业务通道映射。QI用于指示业务对业务通道的需求，例如传输速率、时延、丢包率、通信周期、最大包大小等。
可选的，信息#41还可以包括附加参数，例如传输模式指示信息、是否专载指示信息等。传输模式指示信息用于指示数据的传输模式。是否专载指示信息用于指示业务通道是 否专用于传输某个业务的数据。
与流程300中的步骤S302不同的是，在步骤S402中，信息#41中可以携带的端口信息可以包括第一端口，而不包括第二端口。这是因为在建立单向业务通道时，第一电子设备的基础服务层需要感知本端端口(即第一端口)与本端业务通道组的映射关系。
在步骤S403，第一电子设备的基础服务层(具体为通道管理模块)判断是否创建非缺省业务通道。也即，第一电子设备的基础服务层判断是否创建新的业务通道组。
若否，则通道管理模块不创建非缺省业务通道，而将第一端口映射到已有的业务通道上，以使用已有的业务通道传输新的业务数据。然后通道管理模块执行步骤S411，通知第一电子设备的基础应用层业务通道申请成功，并将第一端口和第一映射标识发送给基础应用层。关于基础服务层判断是否创建非缺省业务通道的实现方式，以及第一映射标识的形式可以参考图3中步骤S303中相关描述，为简洁，在此不再赘述。
若是，则通道管理模块确定创建非缺省业务通道，生成新的业务通道的标识TCID-s。
在步骤S404，第一电子设备的基础服务层(具体为通道管理模块)与第二电子设备的基础服务层(具体为通道管理模块)进行通道参数协商。
具体地，在该步骤中，第一电子设备的通道管理模块可以向第二电子设备的通道管理模块发送通道参数协商请求。相应地，第二电子设备的通道管理模块可以向第一电子设备的通道管理模块发送通道参数协商响应。通过该交互过程进行通道参数的协商。
该步骤为可选步骤。在一些实施例中，第一电子设备和第二电子设备也可以不进行通道参数协商，由通道管理模块可以自行设置通道参数，或者按照预设规则设置通道参数。这里，第一电子设备和第二电子设备可以根据业务的传输模式协商通道参数，具体内容可参考图3中步骤S404的相关描述，为简洁，在此不再赘述。
在步骤S405，第一电子设备的基础服务层向接入层申请逻辑通道。
具体地，在步骤S405中，第一电子设备的基础服务层可以向接入层发送信息#42，该信息#42用于向接入层申请逻辑通道。该信息#42可以包括创建TCID-s的业务需求。
该信息#42可以包括本端业务通道的标识TCID-s、逻辑通道类型指示信息、服务质量QoS等。其中，本端业务通道的标识TCID-s用于接入层建立业务通道和逻辑通道的映射关系。逻辑通道类型指示信息用于指示逻辑通道的类型。QoS用于接入层选择逻辑通道或对逻辑通道的相关参数进行配置等。
可选的，信息#42还可以包括附加参数，例如是否专载指示信息。是否专载指示信息用于指示业务通道是否专用于传输对应的业务数据。
在步骤S406，第一电子设备的接入层将业务通道TCID-s映射到逻辑通道LCID。即，建立业务通道TCID-s与逻辑通道LCID的映射关系。
具体地，在该步骤中，第一电子设备的接入层可以根据传输情况从以下几种方案中选择一种来建立底层逻辑链路：
case#1：将TCID-s映射到已有的逻辑通道LCID，即建立TCID-s与已建立的某个逻辑通道之间的映射关系。
case#2：重配置已有的逻辑通道，并将TCID-s映射到重配后的逻辑通道LCID。
case#3：建立新的逻辑通道，并将TCID-s映射到新的逻辑通道LCID。
关于上述方案所适应的场景可以参考图3中步骤S406的相关描述，为简洁，在此不 再赘述。
在步骤S407，第一电子设备的接入层向基础服务层(具体为通道管理模块)反馈逻辑通道申请成功。
具体地，在该步骤中，第一电子设备的接入层可以向通道管理模块发送信息#43，该信息#43用于指示逻辑通道申请成功，也就是指示业务通道和逻辑通道的映射关系建立。例如，信息#43可以包括创建的业务通道的标识TCID-s和逻辑通道的标识LCID。换言之，接入层通过信息#43将TCID-s和LCID的映射关系返回给基础服务层。
第一电子设备的通道管理模块接收到业务通道和逻辑通道的映射关系后，认为底层逻辑链路已经可以进行传输。
在步骤S408，第一电子设备的基础服务层向第二电子设备的基础服务层发送创建传输通道请求。该创建传输通道请求用于向第二电子设备通知第一电子设备侧的业务通道和逻辑通道的映射关系建立。
具体地，在该步骤中，第一电子设备的基础服务层可以向第二电子设备的基础服务层发送信息#44，该信息#44用于指示第一电子设备已建立本端业务通道和逻辑通道的映射关系，也用于指示第二电子设备建立对端业务通道和逻辑通道的映射关系。
该信息#44可以包括本端业务通道的标识TCID-s和逻辑通道的标识LCID。
在步骤S409，第二电子设备的基础服务层生成对端业务通道的标识TCID-d。
步骤S409完成后，第二电子设备可以认为两个电子设备的基础服务层已经建立了TCID-s和TCID-d的连接，确定TCID-s和TCID-d的映射关系。第二电子设备接收到第一电子设备发送的LCID后，也可以建立业务通道TCID-d与LCID的映射关系，并维护TCID-s和TCID-d的对应关系。
图4示出的步骤S401至步骤S409与图3所示的步骤S301至步骤S309类似，在此未详尽描述步骤S40x之处，参考上文关于步骤S30x的相关内容。
本申请实施例中，由于创建的非缺省业务通道为仅支持单向传输的业务通道，在建立的过程中第二电子设备无需感知端口与业务通道组的映射关系，因此无需绑定对端业务通道所属的业务通道组和第二端口。即流程400相比流程300而言，可以省略步骤S310和步骤S311。
继续参考图4，在步骤S410，第二电子设备的基础服务层向第一电子设备的基础服务层发送创建传输通道响应。该创建传输通道响应用于向第一电子设备通知第二电子设备侧的业务通道和逻辑通道的映射关系建立。
具体地，在该步骤中，第二电子设备的基础服务层可以向第一电子设备的基础服务层发送信息#46，该信息#46可以包括对端业务通道的标识TCID-d和逻辑通道的标识LCID。
步骤S410完成后，第一电子设备可以认为两个电子设备的基础服务层已经建立了TCID-s和TCID-d的连接，第一电子设备可以维护TCID-s和TCID-d的对应关系(即映射关系)。相应地，第一电子设备可以初始化本端业务通道所属的业务通道组内的通道数为1。
在步骤S411，第一电子设备的基础服务层(具体为通道管理模块)通知基础应用层业务通道申请成功。
具体地，在该步骤中，第一电子设备的通道管理模块可以向基础应用层发送信息#47， 该信息#47用于指示本端业务通道TCID-s所属的业务通道组与端口的映射关系。
该信息#47可以包括第一端口port1和第一映射标识，以用于建立第一端口与本端业务通道组的映射关系。这里的第一映射标识即第一电子设备的基础服务层向上层传递的用于指示业务通道所属的组的标识。第一映射标识的形式可以参考图3中步骤S313的相关描述，为简洁，在此不再赘述。
图4示出的步骤S410至步骤S411与图3所示的步骤S312至步骤S313类似，在此未详尽描述步骤之处，参考上文关于图3的相关内容。
本申请实施例中，通过图4所示的流程创建的非缺省业务通道为单向业务通道，即第一电子设备可以利用创建的非缺省业务通道向第二电子设备传输业务，反之则不可以。
本申请实施例中，本端业务通道的标识TCID-s与对端业务通道的标识TCID-d可以不同，也可以相同。在二者不同的情况下，第一电子设备和第二电子设备可以各自维护各自的业务通道标识，这使得在创建非缺省业务通道时更灵活。而在二者相同的情况下，即第一电子设备的基础服务层生成的TCID-s与第二电子设备的基础服务层生成的TCID-d一致时，则有可能出现冲突。
以图3示出的流程为例，如果第一电子设备和第二电子设备同时发起创建非缺省业务通道的流程300，并且本地生成的TCID-s相同(如均为0x0028),当两侧的流程均进行到步骤S309时，会发现双方申请的业务通道的标识TCID一致，即第一电子设备为第一业务传输所申请的业务通道的标识与第二电子设备为第二业务传输所申请的业务通道的标识相同。
为方便理解，参考图5所示，第一电子设备的基础服务层发起创建非缺省业务通道的流程，并本地生成TCID-s＝0x0028，例如执行流程300的步骤S303或流程400的步骤S403。与此同时，第二电子设备的基础服务层也发起创建非缺省业务通道的流程，并本地生成TCID-s＝0x0028，例如执行流程300的步骤S303或流程400的步骤S403。
之后第一电子设备向第二电子设备发送创建传输通道请求，并携带TCID-s＝0x0028，例如执行流程300的步骤S308或流程400的步骤S408。与此同时，第二电子设备向第一电子设备发送创建传输通道请求，并携带TCID-s＝0x0028，例如执行流程300的步骤S308或流程400的步骤S408。
以第一电子设备为例，第一电子设备在自己发起的流程中生成了本端业务通道的标识TCID-s＝0x0028，第一电子设备还在对方发起的流程中充当对端的角色，因此在接收到第二电子设备发送的创建传输通道请求后，需生成对端业务通道的标识TCID-d，例如执行流程300的步骤S309或流程400的步骤S409。若要求在一个流程中，本端和对端生成的业务通道的标识相同，则在第二电子设备发起的流程中，作为对端的第一电子设备生成的TCID-d需要与第二电子设备生成的TCID-s一致，即TCID-d＝0x0028。但是，第一电子设备在自己发起的流程中已经生成了本端业务通道的标识TCID-s＝0x0028。对于第一电子设备而言，出现了在两个创建非缺省业务通道的流程申请相同业务通道标识的情况，这样就产生了冲突，无法继续后续流程。第二电子设备遇到的情形类似，不再赘述。
在这种场景下，为了解决冲突问题，可以选择双方均创建失败，或者引入猜拳机制解决。
选择双方均创建失败的方式比较好理解，即第一电子设备停止第二电子设备发起的创 建非缺省业务通道的流程，第二电子设备停止第一电子设备发起的创建非缺省业务通道的流程，例如在流程300的步骤S312或流程400的步骤S410中携带创建传输通道失败的信息。
若引入猜拳机制，则可以在向对方发送创建传输通道请求时，携带一个用于比较大小的随机数，根据随机数的大小确定是否接收对方的建立链路请求。
为方便理解，参考图6所示，第一电子设备向第二电子设备发送创建传输通道请求，并携带TCID-s＝0x0028以及第一随机数(例如100)。与此同时，第二电子设备向第一电子设备发送创建传输通道请求，并携带TCID-s＝0x0028和第二随机数(例如90)。第一电子设备的基础服务层可以通过比较第一随机数和第二随机数的大小来解决冲突。如第二随机数90小于第一随机数100，则第一电子设备可以拒绝第二电子设备的建立链路请求，停止创建第二电子设备请求创建的非缺省业务通道，例如向第二电子设备反馈创建传输通道失败响应。相应地，第二电子设备的基础服务层可以通过比较第一随机数和第二随机数的大小来解决冲突。如第一随机数100大于第二随机数90，则第二电子设备可以接受第一电子设备的建立链路请求，继续创建第一电子设备请求创建的非缺省业务通道，例如向第一电子设备反馈创建传输通道成功响应。这样，传输通道TCID-s＝0x0028在第一电子设备发起的创建非缺省业务通道的流程中建立，而不会在第二电子设备发起的创建非缺省业务通道的流程中建立，冲突解决。
在一些实施例中，如果第一随机数和第二随机数大小相同，可以使双方均建立失败，拒绝对方的建立链路请求。或者，第一电子设备在发送创建传输通道请求时，可以携带多个第一随机数，该多个第一随机数具有优先级顺序。第二电子设备在发送创建传输通道请求时，可以携带多个第二随机数，该多个第二随机数具有优先级顺序。在比较随机数大小时，可以按照优先级顺序进行比较，即，先比较优先级最高的第一随机数和优先级最高的第二随机数的大小，若二者相同，再继续比较优先级次之的第一随机数和优先级次之的第二随机数的大小，依此类推。
需要说明的是，上述列举的解决冲突的方式仅仅是示例性的，在其他实施例中，可以有其他方式解决，例如预先定义第一电子设备和第二电子设备的优先级，优先级更高的电子设备可以拒绝优先级低的电子设备发送的建立链路请求等，在此不再一一详述。
上文结合图3至图6描述了本申请实施例提供的创建非缺省业务通道的流程，也即创建新的传输通道组的流程。在实际应用中，业务数据不一定在创建的第一个业务通道上传输，而可以在业务通道组中任意的子通道上传输。下面结合图7进行描述。
图7示出了本申请实施例提供的添加非缺省业务子通道的流程示意图。在该流程的实现过程中，涉及第一电子设备和第二电子设备，两个电子设备可以均具有如图2所示的基础应用层230、基础服务层220以及接入层210。图7示出的添加非缺省业务子通道的流程500包括步骤S501至步骤S508，下面结合图7对各个步骤进行详细描述。
进行流程500的前提为第一业务通道组已存在，第一电子设备和第二电子设备正在使用该第一业务通道组进行业务中(例如第一端口与第一业务通道组具有映射关系，第一业务通道组正在传输第一端口下发的数据)，为了实现业务分流，例如业务受阻时，第一电子设备与第二电子设备之间可以进行如下流程，以在该第一业务通道组内添加新的业务通道，即非缺省业务子通道。
需要说明的是，这里所涉及的业务分流，可以理解为是在第一业务通道组内新增业务通道以传输第一端口下发的数据。
在步骤S501，第一电子设备的基础服务层(具体为通道管理模块)生成本端业务通道的标识TCID-s。
可以理解的是，TCID-s需要与已有的正在进行业务的业务通道在同一个业务通道组内。例如，TCID-s可以包括多个比特(bit)，其中部分比特用于标识第一业务通道组的编号(即组编号GroupID)，部分比特用于标识该业务通道在第一业务通道组内的编号，即组内编号LocalID。
在步骤S502，第一电子设备的基础服务层(具体为通道管理模块)与第二电子设备的基础服务层(具体为通道管理模块)进行通道参数协商。
具体地，在该步骤中，第一电子设备的通道管理模块可以向第二电子设备的通道管理模块发送通道参数协商请求。相应地，第二电子设备的通道管理模块可以向第一电子设备的通道管理模块发送通道参数协商响应。通过该交互过程进行通道参数的协商。在协商过程中，第一电子设备和第二电子设备需要交互的信息可以通过控制通道传输。
两个电子设备的通道管理模块所协商的通道参数与数据的传输模式相对应。具体参数描述可参考流程300的步骤S304的相关描述，为简洁，在此不再赘述。
步骤S502为可选步骤。在一些实施例中，第一电子设备和第二电子设备也可以不进行通道参数协商，由通道管理模块可以自行设置通道参数，或者按照预设规则设置通道参数，在此不作过多描述。
在步骤S503，第一电子设备的基础服务层向接入层申请逻辑通道。
具体地，第一电子设备的基础服务层可以向接入层发送信息#52，该信息#52用于向接入层申请逻辑通道。该信息#52包括创建TCID-s的业务需求。
该信息#52可以包括本端业务通道的标识TCID-s、逻辑通道类型指示信息、服务质量QoS等。其中，本端业务通道的标识TCID-s用于接入层建立业务通道和逻辑通道的映射关系。逻辑通道类型指示信息用于指示逻辑通道的类型。QoS用于接入层选择逻辑通道或对逻辑通道的相关参数进行配置等。
可选的，该信息#52还可以包括附加参数，例如是否专载指示信息。是否专载指示信息用于指示业务通道是否专用于传输业务数据。
关于信息#52中所包括的相关参数的说明可以参考流程300的步骤S305的相关描述，为简洁，在此不再赘述。
在步骤S504，第一电子设备的接入层将业务通道TCID-s映射到逻辑通道LCID。即，建立业务通道TCID-s与逻辑通道LCID的映射关系。
具体地，在该步骤中，第一电子设备的接入层可以根据传输情况从以下几种方案中选择一种来建立底层逻辑链路：
case#1：将TCID-s映射到已有的逻辑通道LCID，即建立TCID-s与已建立的某个逻辑通道之间的映射关系。
case#2：重配置已有的逻辑通道，并将TCID-s映射到重配后的逻辑通道LCID。
case#3：建立新的逻辑通道，并将TCID-s映射到新的逻辑通道LCID。
关于接入层的具体决策以及适用场景可以参考流程300中步骤S306的相关描述，为 简洁，在此不再赘述。
在步骤S505，第一电子设备的接入层向基础服务层(具体为通道管理模块)反馈逻辑通道申请成功。
具体地，在该步骤中，第一电子设备的接入层可以向通道管理模块发送信息#53，该信息#53用于指示逻辑通道申请成功，也就是指示业务通道和逻辑通道的映射关系建立。例如，信息#53可以包括添加的业务通道的标识TCID-s和逻辑通道的标识LCID。换言之，接入层通过信息#53将TCID-s和LCID的映射关系返回给基础服务层。
第一电子设备的通道管理模块接收到业务通道和逻辑通道的映射关系后，认为底层逻辑链路已经可以进行传输。
在步骤S506，第一电子设备的基础服务层向第二电子设备的基础服务层发送创建传输通道请求。该创建传输通道请求用于向第二电子设备通知第一电子设备侧的业务通道和逻辑通道的映射关系建立。
具体地，在该步骤中，第一电子设备的基础服务层可以向第二电子设备的基础服务层发送信息#54，该信息#54用于指示第一电子设备已建立本端业务通道和逻辑通道的映射关系。
该信息#54可以包括本端业务通道的标识TCID-s和逻辑通道的标识LCID。
在步骤S507，第二电子设备的基础服务层生成对端业务通道的标识TCID-d。
具体地，第二电子设备的基础服务层判断新的业务通道是现有的业务通道组内的子通道，则在组内分配一个TCID-d。例如，第二电子设备的基础服务层根据此前维护的本端业务通道的标识，可以判断TCID-s是否为已有业务通道组内的子通道。若是，则在对应的对端业务通道组中建立新的子通道TCID-d。
步骤S507完成后，第二电子设备可以认为两个电子设备的基础服务层已经建立了TCID-s和TCID-d的连接，确定并维护TCID-s和TCID-d的映射关系。相应地，第二电子设备可以将对端业务通道组内的子通道数加1。与此同时，第二电子设备的基础服务层可以确定对端业务通道TCID-d与LCID的映射关系。
在步骤S508，第二电子设备的基础服务层向第一电子设备的基础服务层发送创建传输通道响应。该创建传输通道响应用于向第一电子设备通知第二电子设备侧的业务通道和逻辑通道的映射关系。
具体地，在该步骤中，第二电子设备的基础服务层可以向第一电子设备的基础服务层发送信息#56，该信息#56用于指示第二电子设备已建立对端业务通道和逻辑通道的映射关系建立。
该信息#56可以包括对端业务通道的标识TCID-d和逻辑通道的标识LCID。
步骤S508完成后，第一电子设备可以认为两个电子设备的基础服务层已经建立了TCID-s和TCID-d的连接，确定并维护TCID-s和TCID-d的映射关系。相应地，第一电子设备可以将本端业务通道组(即第一业务通道组)内的子通道数加1。
本申请实施例中，当需要业务分流时(例如已有的业务通道受阻)，电子设备的基础服务层可以在已有的业务通道组内自行添加新的业务通道，以用于数据传输，而基础应用层完全不感知基础服务层的操作和流程。经过添加非缺省业务子通道流程之后，同一个业务通道组内会有多个业务通道，在基础应用层下发数据时，通道管理模块可以选择其中一 个业务通道(已有的业务通道或添加的业务通道)进行传输，或者同时在多个业务通道上进行冗余传输，基础应用层并不感知基础服务层确定的传输方式。
本申请实施例中，判断业务通道受阻的方式可以有多种，作为示例而非限定，上层下发的数据一般可以存储在缓存(buffer)队列中，如果基础服务层判断上层累积的buffer数据超过一定百分比时，可以认为业务通道受阻。
可以理解的是，当需要业务分流时，说明第一业务通道组在进行业务传输时不能满足业务需求，该业务需求可以是在创建第一业务通道组时由基础应用层下发给基础服务层的。因此，本申请实施例中，可以认为基础服务层也是根据业务需求判断是否要进行业务分流，即判断是否添加子通道。
由于基础应用层不感知业务数据在基础服务层的传输方式，基础服务层可以根据业务传输情况自行决定新增非缺省业务子通道。当第一电子设备和第二电子设备的接入层支持多种接入技术时，基础服务层可以自行决定在哪种接入技术中新建业务通道，实现对多种接入技术的兼容和对上层的统一，即基础应用层无需感知接入技术，由基础服务层完成相关的通道选择、分流等功能。
上文结合图7描述了本申请实施例提供的添加非缺省子业务通道的流程，也即在已有的业务通道组内添加新的业务通道的流程。在不需要业务分流时，还可以将不再进行传输的业务通道删除。下面结合图8进行描述。
图8示出了本申请实施例提供的删除非缺省子业务通道的流程示意图。在该流程的实现过程中，涉及第一电子设备和第二电子设备，两个电子设备可以均具有如图2所示的基础应用层230、基础服务层220以及接入层210。图8示出的删除非缺省业务子通道的流程600包括步骤S601至步骤S607，下面结合图8对各个步骤进行详细描述。
进行流程600的前提为第一业务通道组已存在，第一电子设备和第二电子设备正在使用该第一业务通道组中的多个业务通道进行业务中(例如使用第一业务通道组中的多个业务通道传输第一端口下发的数据)。当业务不再需要分流时，第一电子设备与第二电子设备之间可以进行如下流程，以在该第一业务通道组内删除不再用于传输数据的业务通道(例如之前用于分流的业务通道)，即非缺省业务子通道。
在步骤S601，第一电子设备的基础服务层(具体为通道管理模块)删除本端业务通道的标识TCID-s。
具体地，在步骤S601之前，第一业务通道组内包括多条业务通道，通道管理模块判断出其中一条业务通道已经不需要进行传输，则通道管理模块删除该条业务通道TCID-s。例如，第一业务通道组内包括业务通道#1和业务通道#2，通道管理模块在很长一段时间内只向业务通道#1传输数据，而没有向业务通道#2传输数据，则通道管理模块可以认为不需要在业务通道#2上进行传输，就可以删除业务通道#2。
在步骤S602，第一电子设备的基础服务层向接入层申请释放逻辑通道。
该步骤即基础服务层申请解除业务通道TCID-s与逻辑通道LCID的映射关系。具体地，第一电子设备的基础服务层可以向接入层发送信息#62，该信息#62用于指示释放与业务通道TCID-s映射的逻辑通道，即指示解除业务通道TCID-s与逻辑通道LCID的映射关系。
该信息#62可以包括本端业务通道的标识TCID-s。
在步骤S603，第一电子设备的接入层结束业务通道TCID-s映射到逻辑通道LCID。
具体地，在该步骤中，第一电子设备的接入层可以根据传输情况，从以下几种方案中选择一种来处理底层逻辑链路：
方案1(case#1)：结束TCID-s映射到已有逻辑通道LCID，并维持已有LCID。
例如，当接入层根据传输情况确定业务通道TCID-s删除后，对现有传输影响不大时，可以解除TCID-s与LCID的映射关系，维持LCID的相关参数配置。示例性的，若该LCID映射了多个业务通道，而TCID-s占LCID传输能力的1％，则删除TCID-s对该LCID的传输影响不大，因此可以不重配该LCID的相关参数。
方案2(case#2)：结束TCID-s映射到已有逻辑通道LCID，并重配已有逻辑通道LCID。
例如，当接入层根据传输情况确定业务通道TCID-s删除后，对现有传输影响较大时，如数据流量大幅降低，可以解除TCID-s与LCID的映射关系，并对该已有逻辑通道LCID进行重配置，以降低该LCID的传输能力。示例性的，若该LCID映射了多个业务通道，而TCID-s占LCID传输能力的90％，则删除TCID-s对该LCID的传输影响加大，需要降低LCID的传输能力。这是因为逻辑通道上边的传输空间是预分配好的，如果设置的QoS能力高，真实传输的少，可能会影响其他的逻辑通道的传输。因此需要对该LCID的相关参数进行重配置。
方案3(case#3)：结束TCID-s映射到已有逻辑通道LCID，并删除已有逻辑通道LCID。
例如，该LCID只映射了一个业务通道，即TCID-s，则删除TCID-s后，该LCID也可以删除。
需要说明的是，上述所列举的几种方案可以认为是图7示出的添加非缺省业务子通道的过程中步骤S504的逆过程。这里所列举的方案以及适用场景仅仅是示例性的，在其他实施例中，接入层在拆除底层逻辑链路时所选择的方式可以有其他方式，上述几种方案所适用的场景还有其他场景，在此不再一一描述。
步骤S603完成后即解除了业务通道和逻辑通道的映射关系。
在步骤S604，第一电子设备的接入层向基础服务层(具体为通道管理模块)反馈逻辑通道释放成功。
具体地，在该步骤中，第一电子设备的接入层可以向通道管理模块发送信息#63，该信息#63用于指示业务通道和逻辑通道的映射关系解除，逻辑链路操作完成。
信息#63可以包括被删除的业务通道的标识TCID-s。
第一电子设备的通道管理模块知道业务通道和逻辑通道的映射关系解除后，认为底层逻辑链路已经拆除。
在步骤S605，第一电子设备的基础服务层向第二电子设备的基础服务层发送删除传输通道请求。该删除传输通道请求用于向第二电子设备通知第一电子设备侧的业务通道和逻辑通道的映射关系解除。
具体地，在该步骤中，第一电子设备的基础服务层可以向第二电子设备的基础服务层发送信息#64，该信息#64用于指示第一电子设备已解除本端业务通道和逻辑通道的映射关系，也用于指示第二电子设备解除对端业务通道和逻辑通道的映射关系。
该信息#64包括被删除的业务通道的标识TCID-s。
在步骤S606，第二电子设备的基础服务层删除对端业务通道的标识TCID-d。
具体地，第二电子设备的基础服务层在创建业务通道的过程中可以感知本端业务通道与逻辑通道的映射关系，因此第二电子设备的基础服务层可以根据该映射关系确定需要解除的对端业务通道与逻辑通道的映射关系，从而删除对端业务通道的标识TCID-d。或者，在创建业务通道的过程中，第二电子设备可以感知TCID-s与TCID-d连接，即TCID-s与TCID-d具有对应关系，因此在步骤S606中，第二电子设备的基础服务层获取到TCID-s后就可以确定需要删除的对端业务通道标识TCID-d。
步骤S606完成后，第二电子设备可以认为两个电子设备的基础服务层已经删除了TCID-s和TCID-d的连接。相应地，第二电子设备可以将对端业务通道TCID-d所属的业务通道组内的通道数减1。与此同时，第二电子设备的基础服务层解除对端业务通道TCID-d与LCID的映射关系。
在步骤S607，第二电子设备的基础服务层向第一电子设备的基础服务层发送删除传输通道响应。该删除传输通道响应用于向第一电子设备通知第二电子设备侧的业务通道和逻辑通道的映射关系解除。
具体地，在该步骤中，第二电子设备的基础服务层可以向第一电子设备的基础服务层发送信息#66，该信息#66用于指示第二电子设备已解除对端业务通道和逻辑通道的映射关系。
该信息#66可以包括对端业务通道的标识TCID-d。
需要说明的是，步骤S605和步骤S607中，第一电子设备的基础服务层与第二电子设备的基础服务层交互的数据可以通过控制通道传输。
步骤S607完成后，第一电子设备可以认为两个电子设备的基础服务层已经删除了TCID-s和TCID-d的连接。相应地，第一电子设备可以将本端业务通道TCID-s所属的业务通道组(即第一业务通道组)内的通道数减1。
本申请实施例中，当业务不再需要分流时，电子设备的基础服务层可以在自行删除业务通道组内的业务通道，而基础应用层完全不感知基础服务层的操作和流程。基础应用层下发的数据，仍然可以通过业务通道组内的其他业务通道进行传输，基础应用层并不感知业务通道的变化。
上文结合图8描述了本申请实施例提供的删除非缺省子业务通道的流程，当业务传输已经结束(即业务停止，例如第一端口不再用于传输数据)时，可以将用于传输该停止业务的业务通道组释放，即释放非缺省业务通道。下面结合图9进行描述。
图9示出了本申请实施例提供的释放非缺省业务通道的流程示意图。在该流程的实现过程中，涉及第一电子设备和第二电子设备，两个电子设备可以均具有如图2所示的基础应用层230、基础服务层220以及接入层210。图9示出的释放非缺省业务通道的流程700包括步骤S701至步骤S709，下面结合图9对各个步骤进行详细描述。
当第一电子设备和第二电子设备之间的业务停止时，第一电子设备与第二电子设备之间可以进行如下流程，以释放第一端口和第二端口。
在步骤S701，第一电子设备的基础应用层通知基础服务层(具体可以为通道管理模块)释放业务通道。
在该步骤中，第一电子设备的基础应用层请求通道管理模块为第一端口和第二端口释放业务通道，可以理解为是解除第一端口与本端业务通道组的映射关系，以及解除第二端 口与对端业务通道组的映射关系。
具体地，第一电子设备的基础应用层可以向通道管理模块发送信息#71，该信息#71用于指示为第一端口和第二端口释放业务通道。
该信息#71可以包括第一端口和第二端口。
在步骤S702，第一电子设备的基础服务层(具体为通道管理模块)判断是否释放非缺省业务通道。也即，第一电子设备的基础服务层判断是否释放业务通道组。
具体地，通道管理模块可以根据端口与业务通道组的映射关系判断是否释放非缺省业务通道。
例如若多个端口映射到同一业务通道组，即与第一端口映射的业务通道组还与其他端口具有映射关系，则不释放非缺省业务通道，即不删除业务通道组。但第一电子设备的基础服务层可以解除第一端口与业务通道组的映射关系，并反馈给基础应用层。示例性的，基础服务层可以执行步骤S709，通知基础应用层第一端口与业务通道组的映射关系解除，第一端口释放。
若第一端口映射到业务通道组具有一对一映射关系，即与第一端口映射的业务通道组与其他端口没有映射关系，则可以释放非缺省业务通道，即删除业务通道组。示例性的，基础服务层在步骤S702中可以执行释放TCID-s，也可以理解为删除TCID-s。
在步骤S703，第一电子设备的基础服务层向接入层申请释放逻辑通道。
该步骤即基础服务层申请解除业务通道TCID-s与逻辑通道LCID的映射关系。具体地，第一电子设备的基础服务层可以向接入层发送信息#72，该信息#72用于指示释放与业务通道TCID-s映射的逻辑通道，即指示解除业务通道TCID-s与逻辑通道LCID的映射关系。
该信息#72可以包括本端业务通道的标识TCID-s。
在步骤S704，第一电子设备的接入层结束业务通道TCID-s映射到逻辑通道LCID。
具体地，第一电子设备的接入层可以根据传输情况，从以下几种方案中选择一种来处理底层逻辑链路：
case#1：结束TCID-s映射到已有逻辑通道LCID，并维持已有LCID。
case#2：结束TCID-s映射到已有逻辑通道LCID，并重配已有逻辑通道LCID。
case#3：结束TCID-s映射到已有逻辑通道LCID，删除已有逻辑通道LCID。
需要说明的是，上述所列举的几种方案可以认为是图3示出的创建非缺省业务通道的过程中步骤S306的逆过程。关于上述方案所适应的场景可以参考图8中步骤S603的相关描述，为简洁，在此不再赘述。
步骤S704完成后即解除了业务通道和逻辑通道的映射关系。
在步骤S705，第一电子设备的接入层向基础服务层(具体为通道管理模块)反馈逻辑通道释放成功。
具体地，在该步骤中，第一电子设备的接入层可以向通道管理模块发送信息#73，该信息#73用于指示业务通道和逻辑通道的映射关系解除，逻辑链路操作完成，逻辑通道释放成功。
信息#73可以包括被释放的业务通道的标识TCID-s。
第一电子设备的通道管理模块知道业务通道和逻辑通道的映射关系解除后，认为底层 逻辑链路已经拆除。
在步骤S706，第一电子设备的基础服务层向第二电子设备的基础服务层发送删除传输通道请求。该删除传输通道请求用于向第二电子设备通知第一电子设备侧的业务通道和逻辑通道的映射关系解除。
具体地，在该步骤中，第一电子设备的基础服务层可以向第二电子设备的基础服务层发送信息#74，该信息#74用于指示第一电子设备已解除本端业务通道和逻辑通道的映射关系，也用于指示第二电子设备解除对端业务通道和逻辑通道的映射关系。
该信息#74包括被释放的业务通道的标识TCID-s。
在步骤S707，第二电子设备的基础服务层释放对端业务通道TCID-d。
具体地，第二电子设备的基础服务层在创建业务通道的过程中可以感知本端业务通道与逻辑通道的映射关系，因此第二电子设备的基础服务层可以根据该映射关系确定需要解除的对端业务通道与逻辑通道的映射关系，从而释放对端业务通道TCID-d。或者，在创建业务通道的过程中，第二电子设备可以感知TCID-s与TCID-d连接，即TCID-s与TCID-d具有对应关系，因此在步骤S707中，第二电子设备的基础服务层获取到TCID-s后就可以确定需要释放的对端业务通道TCID-d。
步骤S707完成后，第二电子设备可以认为两个电子设备的基础服务层已经删除了TCID-s和TCID-d的连接。相应地，第二电子设备可以将对端业务通道TCID-d所属的业务通道组内的通道数减1，为0。与此同时，第二电子设备的基础服务层解除对端业务通道TCID-d与LCID的映射关系。
在一些实施例中，在步骤S707之后，第二电子设备的基础服务层可以通知第二电子设备的基础应用层第二端口释放，即解除了第二端口与对端业务通道组的映射关系，并释放了对端业务通道组。
在步骤S708，第二电子设备的基础服务层向第一电子设备的基础服务层发送删除传输通道响应。该删除传输通道响应用于向第一电子设备通知第二电子设备侧的业务通道和逻辑通道的映射关系解除。
具体地，在该步骤中，第二电子设备的基础服务层可以向第一电子设备的基础服务层发送信息#76，该信息#76用于指示第二电子设备已解除对端业务通道和逻辑通道的映射关系。
该信息#76可以包括对端业务通道的标识TCID-d。
步骤S708完成后，第一电子设备可以认为两个电子设备的基础服务层已经删除了TCID-s和TCID-d的连接。相应地，第一电子设备可以将本端业务通道TCID-s所属的业务通道组内的通道数减1，为0。
可以理解的是，当需要释放的业务通道组内包括多条业务通道时，在释放业务通道过程中，可以依次释放业务通道组内的子通道，直至业务通道组内的通道数为0。或者也可以一次释放业务通道组内的多个子通道，释放多次直至业务通道组内的通道数为0。或者，也可以一次性释放全部的业务通道。后两种情况的过程类似，下面以一次性释放全部的业务通道为例简要描述过程。
例如，在步骤S703中，信息#72中可以包括本端业务通道组内的全部业务通道的标识(即多个TCID-s)，以通知接入层将这些业务通道与逻辑通道的映射关系解除。在步 骤S705中，信息#73可以包括接入层解除映射关系的全部业务通道的标识(即多个TCID-s)。
需要说明的是，本端业务通道组内的多个业务通道所映射的逻辑通道可能支持不同的接入技术，如业务通道A与逻辑通道A具有映射关系，逻辑通道A支持SLB接入技术，业务通道B与逻辑通道B具有映射关系，逻辑通道B支持SLE接入技术。接入层中可以具有不同的功能模块具体实现对相应接入技术的支持，如接入模块A实现SLB技术，接入模块B实现SLE技术。那么在申请释放逻辑通道的过程中(即在步骤S703中)，基础服务层根据接入技术的不同，可以将业务通道的标识发送到对应的模块上。在步骤S704中，由对应的接入模块结束业务通道与逻辑通道的映射关系。例如基础服务层将业务通道A的标识发送到接入模块A，由接入模块A解除业务通道A与逻辑通道A的映射关系；将业务通道B的标识发送到接入模块B，由接入模块B解除业务通道B与逻辑通道B的映射关系。然后在步骤S705，由接入模块A和接入模块B分别反馈已解除映射关系的业务通道的标识。
在步骤S706中，信息#74可以包括本端业务通道组内的已解除逻辑通道映射关系的全部业务通道的标识(即多个TCID-s)。相应地，在步骤S707，第二电子设备的基础服务层将与多个TCID-s对应的TCID-d分别释放。这样在步骤S707完成后，将对端业务通道TCID-d所属的业务通道组内的通道数减为0。
在步骤S708中，信息#76中可以包括对端业务通道组内的全部业务通道的标识(即多个TCID-d)，以通知第一电子设备的基础服务层已解除了这些业务通道与逻辑通道的映射关系。这样在步骤S708完成后，将本端业务通道TCID-s所属的业务通道组内的通道数减为0。
继续参考图9，在步骤S709，第一电子设备的基础服务层(具体为通道管理模块)通知基础应用层业务通道释放成功。即通知基础应用层已经解除了第一端口与业务通道组的映射关系，并且已释放业务通道组(即删除了业务通道组内的全部子通道。
具体地，在该步骤中，第一电子设备的通道管理模块可以向基础应用层发送信息#77，该信息#77用于指示第一端口与第二端口的业务通道已释放完成。
该信息#77可以包括第一端口port1。
在步骤S710，第一电子设备的基础应用层通知第二电子设备的基础应用层第一端口释放，第二电子设备的基础应用层通知第一电子设备的基础应用层第二端口释放。
该过程中所涉及的数据可以通过已经建立的缺省业务通道传输。
本申请实施例中，当业务结束时，基础应用层可以通知基础服务层不再传输数据，可以释放非缺省业务通道。通道管理模块可以依次删除多条子通道，最后释放非缺省业务通道，通知基础应用层释放业务通道成功。从而释放传输资源。
上文结合图3至图9描述了业务通道的相关流程，其中基础服务层在执行创建非缺省业务通道的流程和添加非缺省业务子通道的流程时，本质是一样的，均是建立一条业务通道，区别在于该业务通道是在新的业务通道组中建立，还是在已有业务通道组中建立。若需要在新的业务通道组中建立，则需要在建立业务通道的同时，建立新的业务通道组，这个过程需要基础应用层参与，如提供端口相关信息、维护端口与业务通道组的映射关系等。类似地，基础服务层在执行释放非缺省业务通道的流程和删除非缺省业务子通道的流程时，本质是一样的，均是释放业务通道，区别在于是否将整个业务通道组释放。若需要释放整 个业务通道组，则需要基础应用层参与，如提供端口相关信息、解除端口与业务通道组的映射关系等。
结合上述实施例和附图，本申请实施例提供了一种配置用于传输业务的通道的方法，该方法可以在图1所示的通信系统100中实现，更具体地，在具有如图2所示的协议架构的电子设备中实现，如应用于第一电子设备。该第一电子设备可以包括基础应用层、基础服务层和接入层，其中基础应用层用于下发业务需求，接入层支持多种接入技术(例如包括SLB接入技术和SLE接入技术)。基础应用层可以配置端口，基础服务层可以配置业务通道，接入层可以配置逻辑通道。端口与业务通道具有映射关系，业务通道与逻辑通道具有映射关系，当完成端口-业务通道-逻辑通道的映射关系后，可以认为形成的通道可用于传输业务。
图10示出了本申请实施例提供的一种配置用于传输业务的通道的方法的示意性流程图。如图10所示，该方法可以包括步骤S801至S806。
在步骤S801，基础服务层根据业务需求确定建立第一业务通道。
这里，业务需求是由基础应用层下发的。例如可以是在步骤S801的前一个步骤由基础应用层发送给基础服务层，用于建立第一业务通道；或者，是在建立其他业务通道的时候由基础应用层发送给基础服务层，而在步骤S801中该业务需求同样用于建立第一业务通道。
本申请实施例中，业务需求是指在传输业务时需要满足的一些要求，例如业务通道的类型、服务质量、业务的传输模式、业务通道是否专载等等。当需要建立新的业务通道才能满足业务需求时，基础服务层确定建立第一业务通道。因此，可选的，在步骤S801之前，基础服务层可以先判断是否建立第一业务通道。可以理解的是，这里建立第一业务通道指的建立一个新的业务通道，而不是指复用已经建立好的业务通道。
在一个实施例中，在该步骤中，基础服务层根据业务需求确定建立第一业务通道可以包括：基础服务层生成第一业务通道的标识。作为示例而非限定，在具体实现中，该第一业务通道的标识可以采用上述实施例中所涉及的TCID-s。
在步骤S802，基础服务层向接入层发送第一信息。
该第一信息用于申请支持第一接入技术的逻辑通道。这里第一接入技术是由基础服务层在接入层所支持的多种接入技术中选择得到的。也就是说，基础服务层会指定逻辑通道所支持的接入技术，或者说，基础服务层可以指定在哪一种接入技术上申请逻辑通道。
在一个示例中，接入层所支持的多种接入技术可以包括SLB接入技术和SLE接入技术。在其他一些实施例中，接入层还可以支持现有的接入技术，例如蓝牙、无线保真(wireless fidelity，Wi-Fi)，还可以支持未来的其他星闪联盟接入技术等。
需要说明的是，这里所涉及的接入技术可以理解为是无线短距通信中的接入技术。
在一个实施例中，第一信息可以包括第一业务通道的标识。
作为示例而非限定，第一信息例如可以是图3中的信息#32，图4中的信息#42，或者图7中的信息#52。关于各种信息的说明可参考上文相关描述，为简洁，在此不再赘述。
在一个实施例中，在步骤S802之前，基础服务层可以与第二电子设备进行通道参数协商。这样可以使第一电子设备和第二电子设备对齐通道参数，防止后续过程失败。
示例性的，基础服务层与第二电子设备所协商的通道参数可以与传输模式相关。通道 参数可以包括传输窗口滑窗大小、刷新定时器、最大传输次数、重传定时器等。可以理解的是，第二电子设备也可以包括基础服务层，这里通道参数协商的过程可以发生在第一电子设备的基础服务层和第二电子设备的基础服务层之间。协商过程中交互的数据可以通过控制通道传输。
在另一个实施例中，第一信息还可以包括逻辑通道类型信息和服务质量信息。逻辑通道类型信息用于指示逻辑通道的类型。本申请实施例中，逻辑通道类型可以包括异步逻辑通道、同步逻辑通道、单向逻辑通道、AM模式逻辑通道、UM模式逻辑通道、TM模式逻辑通道等。服务质量信息用于接入层选择逻辑通道或对逻辑通道的相关参数进行配置。
这里关于逻辑通道类型的说明可以参考上文相关描述，为简洁，在此不再赘述。
在步骤S803，基础服务层接收来自接入层的第二信息。
该第二信息用于指示第一业务通道与第一逻辑通道建立映射关系。也就是说，接入层在接收到基础服务层发送的第一信息后，可以在接入层配置第一逻辑通道，然后将第一业务通道和第一逻辑通道建立映射关系，并在步骤S803中通知基础服务层。
在一个示例中，第一逻辑通道可以是已经建立的逻辑通道，也可以是重配置的逻辑通道，还可以是新建立的逻辑通道。
换句话说，接入层可以将之前已经建好的一个逻辑通道作为第一逻辑通道与第一业务通道映射；或者，可以将之前已经建好的一个逻辑通道进行重配置，并将重配置的逻辑通道作为第一逻辑通道与第一业务通道映射；或者，可以建立一个新的逻辑通道作为第一逻辑通道与第一业务通道映射。
在具体实现中，接入层可以根据第一信息并结合接入层的传输情况确定采用哪种方式得到第一逻辑通道，本申请实施例对此不作限定。作为示例而非限定，接入层可以执行如图3中的步骤S306的动作，或者执行如图4中的步骤S406的动作，或者执行如图7中的步骤S504的动作，从而获得第一逻辑通道。关于接入层如何获取第一逻辑通道以及可能适用的场景，可参考上文相关描述，为简洁，在此不再赘述。
在一个实施例中，第二信息可以包括第一业务通道的标识和第一逻辑通道的标识。
作为示例而非限定，第二信息可以是图3中的信息#33，图4中的信息#43，或者图7中的信息#53。关于各种信息的说明可参考上文相关描述，为简洁，在此不再赘述。
在步骤S804，基础服务层向第二电子设备发送第三信息。
第三信息用于指示第二电子设备建立第二业务通道。
本申请实施例中，第一业务通道是第一电子设备侧建立的，第二业务通道是第二电子设备侧建立的，当第一业务通道和第二业务通道完成映射时，第一电子设备和第二电子设备才能通过第一业务通道和第二业务通道传输业务。
第二电子设备也可以包括基础应用层、基础服务层和接入层。本申请实施例中，第一电子设备的基础服务层可以向第二电子设备的基础服务层发送该第三信息。具体地，该第三信息可以通过第一电子设备和第二电子设备之间建立的控制通道进行传输。
在一个实施例中，第二电子设备可以生成第二业务通道的标识。更为具体地，可以是第二电子设备的基础服务层生成第二业务通道的标识。作为示例而非限定，在具体实现中，该第一业务通道的标识可以采用上述实施例中所涉及的TCID-d。
本申请实施例中，第二业务通道的标识和第一业务通道的标识可以是独立的，即第一 电子设备和第二电子设备分别具有生成业务通道标识的预设规则，两个电子设备在生成各自的业务通道的标识时，互不影响。
当然，第一业务通道的标识和第二业务通道的标识也可以设置为相同，这种情况下，在生成业务通道的标识的可以同时生成随机数，该随机数可用于解决在第一电子设备和第二电子设备同时执行图10所示方法时可能产生的冲突问题。具体解决方案可以参考上文有关图5和图6的相关描述，为简洁，在此不再赘述。
在一个实施例中，第二电子设备在建立第二业务通道以后，可以建立第二业务通道与第一逻辑通道的映射关系。第二电子设备完成第二业务通道与第一逻辑通道的映射关系后，可以认为第一业务通道和第二业务通道建立连接，底层的逻辑通道也可以进行业务传输。
在一个实施例中，第三信息可以包括第一业务通道的标识和第一逻辑通道的标识。
作为示例而非限定，第三信息可以是图3中的信息#34，图4中的信息#44，或者图7中的信息#54。关于各种信息的说明可参考上文相关描述，为简洁，在此不再赘述。
在步骤S805，基础服务层接收来自第二电子设备的第四信息。
该第四信息用于指示第二业务通道与第一逻辑通道建立映射关系。
在一个实施例中，第四信息可以包括第二业务通道的标识和第一逻辑通道的标识。
作为示例而非限定，第四信息可以是图3中的信息#36，图4中的信息#46，或者图7中的信息#56。关于各种信息的说明可参考上文相关描述，为简洁，在此不再赘述。
在步骤S806，基础服务层根据第四信息确定第一业务通道和第二业务通道的映射关系，完成第一业务通道的建立。
在该步骤中，基础服务层根据第四信息可以获知第二业务通道与第一逻辑通道的映射关系，同时知道第一业务通道与第一逻辑通道的映射关系，因此可以确定第一业务通道和第二业务通道的映射关系，完成了第一业务通道的建立。这样，基础服务层可以认为第一业务通道和第二业务通道建立了连接，第一业务通道、第一逻辑通道和第二业务通道所形成的通道可用于后续业务的传输。
在一些实施例中，基础服务层还可以配置业务通道组，其中业务通道组中可以包括一个或多个业务通道。
本申请实施例中，第一业务通道属于第一业务通道组，第一业务通道组包括至少一个业务通道。第一业务通道组与第一电子设备的第一端口具有映射关系，第一业务通道组用于传输第一端口下发的数据。第二业务通道属于第二业务通道组，第二业务通道组包括至少一个业务通道。第二业务通道组与第二电子设备的第二端口具有映射关系，第二业务通道组用于传输第二端口下发的数据。其中，第一端口、第一业务通道、第一逻辑通道、第二业务通道和第二端口用于在第一电子设备和第二电子设备之间传输业务。
这里，第一业务通道可以是第一业务通道组中建立的第一条业务通道，也可以是第一业务通道组中建立的除第一条业务通道之外的业务通道。当第一业务通道为第一业务通道组中建立的第一条业务通道时，在建立第一业务通道的同时，需要建立第一业务通道组。当第一业务通道不是第一业务通道组中建立的第一条业务通道时，建立第一业务通道可以认为是在已经建立好的第一业务通道组中建立子通道。
在一个示例中，若第一业务通道不是第一业务通道组中建立的第一条业务通道，则在步骤S801中，基础服务层根据业务需求确定建立第一业务通道，可以包括：当第一业务 通道组的传输状态不满足业务需求时，基础服务层确定在第一业务通道组中新建第一业务通道。
换言之，第一业务通道组已经建立，并用于传输第一端口下发的数据。若第一业务通道组的传输状态不满足业务需求时，例如当前传输状态不满足服务质量或业务通道受阻，则基础服务层可以在第一业务通道组中添加子通道，即建立第一业务通道，从而进行业务分流。在具体实现中，基础服务层可以根据业务需求的不同采用多种方式来判断是否要建立第一业务通道。
用于业务分流的第一业务通道可以与第一业务通道组内的其他业务通道采用不同的接入技术，或者使用不同的频谱资源等，从而实现分流。
在一个示例中，若第一业务通道为第一业务通道组中建立的第一条业务通道，则需要基础应用层发起创建业务通道组的流程。因此，步骤S801之前，基础服务层可以接收基础应用层发送的业务需求，该业务需求指示基础服务层创建第一业务通道组。在步骤S801中，基础服务层根据业务需求的指示确定建立第一业务通道，其中第一业务通道为第一业务通道组中的第一条业务通道。
作为示例而非限定，例如业务需求中指示业务通道专用于传输某一业务的数据，或者业务需求中指示业务数据的传输方式为透传模式，则基础服务层确定新建第一业务通道，且该第一业务通道属于新的业务通道组。
在一些实施例中，在基础服务层接收基础应用层发送的业务需求之前，基础应用层与第二电子设备可以进行端口协商，确定第一电子设备使用第一端口，第二电子设备使用第二端口。
也就是说，在基础服务层发送业务需求来指示基础服务层创建第一业务通道组之前，基础服务层需要与第二电子设备端口协商，以确定为哪个端口创建第一业务通道组。
本申请实施例中，第二电子设备也可以包括基础应用层，因此端口协商过程可以发生在第一电子设备的基础服务层和第二电子设备的基础服务层之间。端口协商过程所交互的信息，可以通过缺省业务通道传输。
对于第一业务通道为第一业务通道组中建立的第一条业务通道(即建立第一业务通道的同时需要建立第一业务通道组)的情况，图10所示的方法还可以包括步骤S807和步骤S808，如图10所示。
在步骤S801之前，执行步骤S807，基础服务层接收基础应用层发送的第五信息。
该第五信息用于指示为第一端口申请业务通道。第一端口即第一电子设备和第二电子设备协商确定的端口。这里第一端口为电子设备侧用于传输业务的端口。可以理解的是，在第一电子设备和第二电子设备协商了端口的情况下，第五信息用于指示为第一端口申请业务通道，可以理解为是用于指示为第一端口和第二端口申请业务通道。
作为示例而非限定，第五信息可以是图3中的信息#31，或者图4中的信息#41。关于各种信息的说明可参考上文相关描述，为简洁，在此不再赘述。
在步骤S806之后，执行步骤S808，基础服务层向基础应用层发送第六信息。
该第六信息用于指示第一端口与第一业务通道组建立映射关系。
作为示例而非限定，第六信息可以是图3中的信息#37，或者图4中的信息#47。关于各种信息的说明可参考上文相关描述，为简洁，在此不再赘述。
本申请实施例中，第一业务通道可以是双向传输通道，即用于第一电子设备和第二电子设备相互传输业务。第一业务通道可以是单向传输通道，即用于第一电子设备向第二电子设备传输业务，而不能用于第二电子设备向第一电子设备传输业务。
在一个实施例中，若第一业务通道为双向传输通道，则第五信息可以包括第一端口的标识和第二端口的标识。第六信息可以包括第一端口的标识和第一映射标识，其中第一映射标识用于指示第一业务通道组。
由于第一业务通道为双向传输通道，因此基础应用层在为端口申请业务通道时，需要将第一电子设备和第二电子设备协商的端口均通知基础服务层，才能建立可用于双向传输的第一业务通道。
在一个实施例中，若第一业务通道为单向传输通道，第五信息可以包括第一端口的标识。第六信息可以包括第一端口的标识和第一映射标识，其中第一映射标识用于指示第一业务通道组。
本申请实施例中，第一映射标识表示为第一业务通道组的标识，如上文的GoupID，可以表示为第一业务通道的标识，如上文的TCID，还可以表示为传输通道映射标识，如上文的MapTCID。关于GoupID、TCID以及MapTCID的表示形式可以参考上文相关描述，为简洁，在此不再赘述。
在一些实施例中，第五信息还可以包括业务通道类型信息和服务质量指示信息。其中业务通道类型信息用于指示业务的类型，如指示第一业务通道为单播业务通道、组播业务通道或广播业务通道。服务质量指示信息用于指示业务对业务通道的需求，例如传输速率、时延、丢包率、通信周期、最大包大小等。
在一些实施例中，第五信息还可以包括附加参数，例如传输模式信息、是否专载指示信息等。其中传输模式信息用于指示数据的传输模式，其中传输模式可以包括基础模式、透传模式、普通模式、流控模式、流模式、重传模式等。是否专载指示信息用于指示第一业务通道是否专用于传输第一端口下发的数据。
关于业务通道类型、传输模式等，可以参考上述图3至图9的实施例中的相关描述，为简洁，在此不再赘述。
本申请实施例中，第一电子设备的接入层可以支持多种接入技术，例如SLB接入技术和SLE接入技术。当第一电子设备与第二电子设备需要进行无线业务或业务分流时，用户无需选择或指定在哪个接入技术上进行业务传输，由基础服务层根据业务需求自行选择底层接入技术，并建立业务通道进行传输。这样可以实现对多种接入技术的兼容和对上层的统一，即基础应用层无需感知接入技术，由基础服务层完成通道创建、分流等功能。
图10所示的方法描述了建立第一业务通道的过程，在一些实施例中，在不需要第一业务通道传输业务时，还可以将第一业务通道释放。图11示出了本申请实施例提供的另一种配置用于传输业务的通道的方法的示意性流程图。如图11所示，该方法可以包括步骤S801至S808以及步骤S901至S906。
步骤S801至S808用于建立第一业务通道，步骤S901至S906用于释放第一业务通道。建立第一业务通道过程与图10所示的步骤S801至S808相同，具体可参考图10相关描述，为简洁，在此不再赘述。下面仅对释放第一业务通道的过程进行详细描述。
如图11所示，在步骤S801至S808中，建立第一业务通道。
在步骤S901，当满足预设条件时，基础服务层确定释放第一业务通道。
本申请实施例中，若第一业务通道组包括多条业务通道，第一业务通道为该多条业务通道中的一个时，则释放第一业务通道的过程为删除业务通道组中子通道的过程。若第一业务通道组包括一条业务通道，即该第一业务通道时，则释放第一业务通道的过程也可以认为时释放第一业务通道组的过程，即释放第一业务通道的同时，释放第一业务通道所属的业务通道组。
在一个示例中，预设条件可以包括：第一业务通道在预设时长内未传输数据。
也就是说，第一业务通道在很长时间内没有进行传输业务，那么就可以将第一业务通道释放。
在另一个示例中，预设条件可以包括：基础服务层接收到基础应用层发送的指示信息，指示信息用于指示释放第一业务通道所属的第一业务通道组，其中第一业务通道组与第一电子设备的第一端口具有一对一映射关系，第一业务通道组用于传输第一端口下发的数据。
也就是说，当基础服务层接收到基础应用层的指示信息时，可以根据指示信息释放第一业务通道。需要说明的是，这里基础服务层需要结合端口与业务通道组的映射情况，判断是否释放第一业务通道。例如，当第一端口与第一业务通道组为一对一映射关系时，确定释放第一业务通道。
在步骤S902，基础服务层向接入层发送第七信息。
该第七信息用于申请释放第一逻辑通道。这里第一逻辑通道与第一业务通道具有映射关系。
在一个实施例中，第七信息可以包括第一业务通道的标识。
作为示例而非限定，第七信息可以是图8中的信息#62，或者图9中的信息#72。关于各种信息的说明可参考上文相关描述，为简洁，在此不再赘述。
在步骤S903，基础服务层接收来自接入层的第八信息。
该第八信息用于指示第一业务通道与第一逻辑通道解除映射关系。
在一个实施例中，第八信息可以包括第一业务通道的标识。
作为示例而非限定，第八信息可以是图8中的信息#63，或者图9中的信息#73。关于各种信息的说明可参考上文相关描述，为简洁，在此不再赘述。
在一些实施例中，第一逻辑通道的参数可以维持不变或者被重配置。或者第一逻辑通道被删除。在具体实现中，接入层可以根据实际情况对第一逻辑通道进行处理，详细可参考图8-9的相关描述。
在步骤S904，基础服务层向第二电子设备发送第九信息。
该第九信息用于指示第二电子设备释放第二业务通道，即指示第二电子设备解除第二业务通道与第一逻辑通道的映射关系。
在一个实施例中，第九信息可以包括第一业务通道的标识。
作为示例而非限定，第九信息可以是图8中的信息#64，或者图9中的信息#74。关于各种信息的说明可参考上文相关描述，为简洁，在此不再赘述。
相应地，第二电子设备接收到第九信息后，可以释放第二业务通道。
在步骤S905，基础服务层接收来自第二电子设备的第十信息。
该第十信息用于指示第二业务通道与第一逻辑通道解除映射关系。
在一个实施例中，第十信息可以包括第二业务通道的标识。
作为示例而非限定，第十信息可以是图8中的信息#66，或者图9中的信息#76。关于各种信息的说明可参考上文相关描述，为简洁，在此不再赘述。
需要说明的是，步骤S904和S905可以发生在第一电子设备的基础服务层和第二电子设备的基础服务层之间，其中两个设备交互的信息可以通过控制通道传输。
在步骤S905，基础服务层根据第十信息确定第一业务通道和第二业务通道解除映射关系，完成第一业务通道的释放。
当基础服务层接收到第十信息后，可以认为第一电子设备和第二电子设备之间的底层链路拆除，第一业务通道和第二业务通道断开连接。
上文提到，当第一业务通道为第一业务通道组内的唯一一条业务通道时，在释放第一业务通道的同时需要释放第一业务通道组。因此在一些实施例中，当需要同时释放第一业务通道组时，在步骤S901之前，图11所示的方法还可以包括步骤S907和S908，如下。
在步骤S901之前，执行步骤S907，基础服务层接收基础应用层发送的第十一信息。
该第十一信息用于指示为第一电子设备的第一端口释放业务通道，其中第一端口与第一业务通道组具有映射关系，第一业务通道组包括第一业务通道。
在一个实施例中，第十一信息可以包括第一端口的标识。
作为示例而非限定，第十一信息可以是图9中的信息#71。关于信息#71的说明可参考上文相关描述，为简洁，在此不再赘述。
在步骤S906之后，执行步骤S908，基础服务层接收基础应用层发送的第十二信息。
该第十二信息用于指示第一端口与第一业务通道组解除映射关系。
在一个实施例中，第十二信息可以包括第一端口的标识。
作为示例而非限定，第十二信息可以是图9中的信息#77。关于信息#77的说明可参考上文相关描述，为简洁，在此不再赘述。
本申请实施例中，当业务结束或者不需要业务通道分流时，可以释放第一业务通道，从而释放传输资源，提高资源利用率。
上述图10和图11所示的方法中，基础应用层可以是图2所示的基础应用层230，由基础应用层所执行的操作，具体可以由如图2所示的基础应用层230中的相应业务模块执行。基础服务层可以是图2所示的基础服务层220，由基础服务层所执行的操作，具体可以由如图2所示的基础服务层230中的通道管理模块执行。接入层可以是图2所示的接入层210，由接入层所执行的操作，具体可以由如图2所示的接入层210中的相应接入模块执行。
