S101：建立终端设备101与第一接入设备102之间的第一通道，所述第一接入设备102与第二接入设备103连接，所述第一通道承载于第一无线接口，所述第一无线接口的制式为第一制式，其中，第一接入设备102与第二接入设备103之间连接。
S102：终端设备101接收所述第一接入设备102在第二制式的标识，所述第一制式与所述第二制式不同。
示例性的，第一制式与第二制式可分别为NR SL制式、wifi制式或者LTE SL制式中的一种，且第一制式与第二制式为不同的网络制式。具体的，第一制式可以是wifi制式，第二制式可以是NR SL制式。
在S102的实施中，终端设备101可接收第一接入设备102发送的所述第一接入设备102在第二制式的标识。示例性的，第一接入设备102可在第一制式广播消息中包含第一接入设备102在第二制式的标识，或者第一接入设备102可向终端设备101直接发送第一接入设备102在第二制式的标识。具体的，以上第一接入设备102在第二制式的标识可以包含在第一接入设备102向终端设备101发送的消息或数据的介质访问控制(media access control，MAC)层协议头、无线链路层控制(radio link control，RLC)层协议头或物理(physical，PHY)层协议头中。
或者，终端设备101可接收第二接入设备103发送的所述第一接入设备102在第二制式的标识。例如，所述第一接入设备102在第二制式的标识可包含在第二接入设备103向终端设备101发送的RRC消息(以下可称为第一RRC消息)中。
S103：终端设备101根据所述第一接入设备102在第二制式的标识，建立和所述第一接入设备102之间的第二通道，所述第二通道承载于第二无线接口，所述第二无线接口的制式为第二制式。
具体地，以第二制式是wifi制式为例，终端设备101可以通过wifi方式收听到第一接入设备102广播的其在第二制式的标识。当终端设备101判断接收到的第一接入设备在wifi制式的标识和自己保存的所述第一接入设备102在wifi制式的标识一致时，所述终端设备101申请和第一接入设备102建立连接，即建立和所述第一接入设备102之间的第二通道。或者所述终端设备通过wifi方式主动发起询问，询问消息中包含所述第一接入设备102在第二制式的标识，当收到所述第一接入设备102的答复消息后，所述终端设备101可以请求和第一接入设备102建立连接。
在本申请的实施中，终端设备101可通过第一接入设备102向第二接入设备103发送RRC请求消息，以请求建立终端设备与第二接入设备之间的端到端的RRC连接。示例性的，可在S101之后，由终端设备101发送该RRC请求消息。
例如，上述RRC请求消息可以是RRC建立请求(RRC setup request)，RRC恢复请求(RRC resume request)或者RRC重建立请求(RRC restablishment request)。具体的，RRC 请求消息可作为终端设备101与第一接入设备102之间第一制式的负载(payload)进行传输。如图3所示，终端设备101在发送RRC请求消息时，可在RRC请求消息外封装第一制式的协议规定的分组数据汇聚(packet data convergence protocol，PDCP)协议层、RLC、MAC协议层或者physical，PHY协议层中的部分或全部协议层。
其中，PDCP协议层为终端设备101和第二接入设备103之间端到端的协议层。另外，若RRC请求消息为终端设备101上行发送的首个RRC消息，例如RRC建立请求，其在公共控制信道(common control channel，CCCH)上传输，此时PDCP实体尚未建立，则可不封装PDCP协议层。对于后续终端设备101和第二接入设备103之间建立了RRC连接，则RRC请求消息传输时有对应的PDCP实体，则可封装PDCP协议层。例如信令资源承载(signalling radio bearer，SRB)1和SRB2分别有自己对应的PDCP实体。将终端设备封装后的RRC消息称为第一消息。其中PDCP协议层为终端设备和第二接入网设备端到端的协议层，即LTE Uu或NR Uu协议规定的PDCP协议层。而RLC协议层、MAC协议层以及PHY协议层为终端设备和第一接入设备端到端的协议层，即第一制式(例如LTE SL，NR SL或wifi)协议规定的RLC/MAC/PHY协议层。第一接入设备收到后，解析并去除所述第一制式对应的RLC/MAC/PHY协议层，将处理后的第一消息再封装上RLC协议层、MAC协议层以及PHY协议层，其中RLC/MAC/PHY协议层为第一接入设备和第二接入设备之间端到端的协议层，为LTE Uu或NR Uu协议规定的RLC/MAC/PHY协议层。将第一接入设备处理后的RRC请求消息通过LTE Uu或NR Uu发送给第二接入设备，第二接入设备接收后，首先解析并去除第一接入设备和第二接入设备之间的RLC、MAC以及PHY协议层，接着解析并去除终端设备和第二接入设备之间的所述PDCP协议层，最终获取到终端设备发送给第二接入设备的RRC请求消息。
以上RLC协议层、MAC协议层以及PHY协议层为终端设备101和第一接入设备102之间的第一制式端到端协议栈。当第一制式为SL制式的情况，RLC协议层、MAC协议层以及PHY协议层均可能存在。对于wifi制式的情况，终端设备101和第一接入设备102之间不存在RLC协议层，则可不封装RLC协议层。
具体来说，终端设备101在向第一接入设备102发送RRC请求消息时可指示负载为一个RRC消息，则第一接入设备102在解析出RRC请求消息后可将RRC请求消息作为负载放在第一接入设备102和第二接入设备103之间的空口进行传输。如图3所示，封装RRC请求消息的适配层(adaptation layer)协议层、PDCP协议层、RLC协议层、MAC协议层以及PHY协议层均为第一接入设备102和第二接入设备103之间端到端的协议栈。
在一种具体的示例中，第一接入设备102可向第二接入设备103指示该第一制式，以指示终端设备101通过第一制式接入第一接入设备102。示例性的，第一接入设备102可在RRC请求消息的适配层中增加第一制式的信息，第一制式的信息可用于指示终端设备101通过第一制式接入第一接入设备102。该第一制式的信息可包括终端设备101在第一制式下的标识和/或第一通道对应的第一无线接口的信息(如用于指示第一制式为wifi制式、SL制式或者LTE/NR SL制式的信息)。其中，终端设备101在第一制式下的标识，例如，终端设备101的SL通信的层2(layer-2，L2)标识(SL UE L2 ID)、终端设备101通过wifi网络通信的媒体访问控制(media access control，MAC)地址等，可用于表示终端设备101通过第一制式连接至第一接入设备102。
例如图3所示，在接收RRC请求消息后，第二接入设备103可通过第一接入设备102 向终端设备101返回其为终端设备101分配的第一标识，该第一标识可以是小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)。该第一标识可承载于第二RRC消息，例如RRC建立(RRC setup)消息、RRC回复(RRC resume)消息或者RRC重建立(RRC restablishment)消息。当第一接入设备102在RRC请求消息的适配层或RLC或MAC或PHY层中封装了终端设备101在第一制式下的标识时，第二接入设备103可获得第一标识与终端设备101在第一制式下的标识的对应关系。以上第二RRC消息可用于表示终端设备101与第二接入设备103之间的RRC连接建立完成。
此外，在S104之后，终端设备101可通过第二通道向第一接入设备102发送第三RRC消息，第一接入设备102可在向第二接入设备103转发第三RRC消息时，在第三RRC消息的适配层封装终端设备101在第二制式下的标识和/或第二通道对应的第二无线接口的信息(或称第二制式的信息)，以指示终端设备101通过第二制式连接至第一接入设备102。其中，第一无线接口的信息以及第二无线接口的信息用于确定第一无线接口的制式与第二无线接口的制式不同。终端设备发送的所述第三RRC消息中可以包含第二接入设备103分配的第一标识。从而第二接入设备103可确定终端设备101通过两种不同的制式连接至第一接入设备102，即可以确定终端设备101的第一标识、终端设备101在第一制式下的标识以及终端设备101在第二制式下的标识三者之间的映射关系。
在另一种具体的示例中，可由终端设备101向第二接入设备103指示该第一制式，以指示终端设备101通过第一制式接入第一接入设备102，另外，在S103之后，可由终端设备101向第二接入设备103指示第二制式，以表示终端设备101通过第二制式接入第二接入设备103。具体的，终端设备101可在发送RRC请求消息时，携带第一通道对应的第一无线接口的信息，以及，在发送第三RRC消息时，携带第二通道对应的第二无线接口的信息，第一接入设备102可分别将RRC请求消息和第三RRC消息发送至第二接入设备103，第二接入设备103分别接收第一无线接口的信息以及RRC请求消息以及接收第二无线接口的信息以及第三RRC消息，从而根据第一无线接口的信息以及第二无线接口的信息获知第一无线接口的制式与所述第二无线接口的制式不同。
在S102的一种示例中，终端设备101可接收来自于第二接入设备103的所述第一接入设备102在第二制式的标识。具体的，若第二制式为wifi制式，以上第一接入设备102在第二制式的标识可包括服务集标识(service set identifier,SSID)、基本服务集标识(basic service set identifier，BSSID)或者均匀扩展服务集标识(homogenous extended service set identifier，HESSID)中的任意一个或多个。其中，BSSID即wifi网络的MAC地址。若第二制式为SL制式，如NR SL或LTESL，第一接入设备102在第二制式的标识可包括第一接入设备102的层2(layer-2，L2)标识，如SL L2 ID；若第二制式为SL制式，第一接入设备102在第二制式的标识可包括站点标识(station ID)。
另外，第一接入设备102还可通过第一制式广播第一接入设备102支持通过第二制式进行通信的指示信息和/或第一接入设备102在第二制式工作的频率信息，以便终端设备101进行接入。具体的，若第二制式为wifi制式，第一接入设备102支持通过第二制式进行通信的指示信息可包括wifi支持(wifi-supported)信息；第一接入设备102在第二制式工作的频率信息例如第一接入设备102在第二制式工作的频点和/或信道信息。若第二制式为SL制式，第一接入设备102支持通过第二制式进行通信的指示信息可包括LTE SL支持(LTE-SL-supported)信息，NR SL支持(NR-SL-supported)信息或者SL支持(SL supported) 信息；第一接入设备102在第二制式工作的频率信息例如第一接入设备102在SL工作的频点、发送资源池或者接收资源池等信息中的至少一种信息。
应理解，当第一接入设备102在第二制式的标识来自于该第一接入设备102时，本申请并不限制以上S102的执行时序，该S102的执行也可以在S101之前。
如图4所示，若第一接入设备102在第二制式的标识来自于第一接入设备102，本申请实施例提供的一种通信方法可包括以下步骤：
S201：终端设备101在第一制式下建立与第一接入设备102之间的第一通道，所述第一通道承载于第一无线接口，所述第一无线接口的制式为第一制式。
S202：终端设备101通过第一通道向第一接入设备102发送RRC请求消息，RRC请求消息用于请求建立终端设备101与第二接入设备103之间的端到端的RRC连接。
相应地，第一接入设备102接收终端设备101通过第一通道发送的RRC请求消息。
S203：第一接入设备102向第二接入设备103发送RRC请求消息，并通知第二接入设备所述终端设备101在第一制式下的标识和/或第一通道对应的第一无线接口的信息。
S204：第二接入设备103接收RRC请求消息，同时获得终端设备101在第一制式下的标识和/或第一通道对应的第一无线接口的信息。
S205：第二接入设备103通过第一接入设备102，向终端设备101发送第二RRC消息，第二RRC消息中携带第二接入设备103为终端设备101分配的第一标识，如C-RNTI。
相应地，终端设备101接收第二RRC消息，获得第二接入设备103为终端设备101分配的第一标识。
S206：终端设备101接收第一接入设备102在第二制式的标识。示例性的，该第一接入设备102在第二制式的标识来自于第一接入设备102，例如，可以是第一接入设备102广播的。
应理解，S206的时序可以在S205之前，例如，在S201之前。
S207：终端设备101根据第一接入设备102在第二制式的标识，建立和所述第一接入设备102之间的第二通道，所述第二通道承载于第二无线接口，所述第二无线接口的制式为第二制式。
S208：终端设备101通过第二通道向第一接入设备102发送第三RRC消息，该第三RRC消息中携带第二接入设备103为终端设备101分配的第一标识。
相应地，第一接入设备102接收终端设备101通过第二通道发送的第三RRC消息。
S209：第一接入设备102向第二接入设备103发送所述第三RRC消息，并通知第二接入设备102终端设备101在第二制式下的标识和/或第二通道对应的第二无线接口的信息。
S210：第二接入设备103接收第三RRC消息，获得第二接入设备103为终端设备101分配的第一标识、终端设备101在第二制式下的标识和/或第二通道对应的第二无线接口的信息的对应关系，确定终端设备101通过第一通道以及第二通道连接至第一接入设备102。
在S102的另一种示例中，终端设备101可接收来自于第二接入设备103的所述第一接入设备102在第二制式的标识。所述第一接入设备102在第二制式的标识的设置方式可参见上述介绍。
示例性的，第一接入设备102可向第二接入设备103发送第一接入设备102支持的制式以及第一接入设备102在其支持的制式下的标识。例如，第一接入设备102支持第一制式以及第二制式，则第一接入设备102可发送第一接入设备102在第一制式的标识以及第 一接入设备102在第二制式的标识，所述第一接入设备在第一制式的标识和第一接入设备在第二制式的标识之间存在对应关系。例如，第一接入设备102为HAP，HAP向第二接入设备103上报的内容可以包括第一制式的信息(如用于指示wifi制式或LTE/NR SL制式的信息)和HAP在第一制式下的标识，以及第二制式信息和HAP在第二制式下的标识，例如：wifi，HAP wifi ID以及SL，HAP SL ID。此外，还可以将SL划分为LTE SL或NR SL，则HAP SL ID可替换为HAP LTE SL ID或HAP NR SL ID。或者HAP可向第二接入设备103上报HAP在第一制式的标识以及HAP在第二制式的标识，例如HAP上报的内容为HAP wifi ID以及HAP SL ID，其中，HAP wifi ID的标识名称表示其为wifi制式下的标识，HAP SL ID的标识名称表示其为SL制式下的标识。从而第二接入设备103直接从标识名称就可以识别HAP分别在不同制式下的标识。
另外，当第一接入设备102支持与终端设备101进行通信的网络制式的数量大于3个(如，NR SL、LTE SL、wifi或者未来更多的网络制式)，第一接入设备102还可向第二接入设备103发送第一接入设备102在这3个或3个以上网络制式下分别的标识。具体方式可参照以上示例，在此不再进行具体展开。
该示例中，假设第一接入设备102首先作为终端设备接入第二接入设备103，第二接入设备103为第一接入设备102分配空口标识C-RNTI。接着第一接入设备102向第二接入设备103上报其在第二制式下的标识，例如上报第二制式以及其在第二制式下的标识，如LTE-SL-supported信息，HAPLTE SL ID等。除此之外，第一接入设备102还可以上报其在第一制式下的标识，例如上报第一制式以及其在第一制式下的标识，例如wifi–supported信息，HAP wifi ID等。从而第二接入设备103获取了第一接入设备102的C-RNTI和第一接入设备102在第二制式下的标识的对应关系，或者，第二接入设备103获取了第一接入设备102的C-RNTI、第一接入设备102在第一制式下的标识以及第一接入设备102在第二制式下的标识三者之间的对应关系。后续当第一接入设备102转发来自终端设备101的RRC请求消息时，第二接入设备103可识别第一接入设备的C-RNTI，例如第二接入设备103根据之前为第一接入设备102分配的时频资源识别对应的C-RNTI。从而第二接入设备103可根据所述C-RNTI以及第一接入设备102的C-RNTI和第一接入设备102在第二制式下的标识的对应关系(或者第一接入设备102的C-RNTI、第一接入设备102在第一制式下的标识以及第一接入设备102在第二制式下的标识三者之间的对应关系)确定第一接入设备102在第二制式下的标识。此后，第二接入设备103可向终端设备101发送第一接入设备102在第二制式的标识，该第一接入设备102在第二制式的标识可承载于第一RRC消息，例如第一RRC消息为RRC重配置消息。
另外在该示例中，第二接入设备103在向终端设备101发送第一接入设备102在第二制式的标识以外，还可配置并向终端设备101发送终端设备101在第二制式的标识，第二接入设备103保存终端设备101的第一标识以及终端设备101在第二制式的标识的对应关系，该对应关系可用于判断通过多个通道传输的不同RRC消息是否来自于同一个终端设备101。
比如，终端设备101此后可向第一接入设备102发送终端设备101在第二制式的标识，当终端设备101通过第二通道向第二接入设备103发送第三RRC消息时，第一接入设备102可在第三RRC消息的适配层中携带终端设备101在第二制式的标识，第二接入设备103在解析适配层后，若确定解析得到的标识与自身存储的终端设备101的第一标识对应 的终端设备101在第二制式的标识一致，则第二接入设备103可确定该第一标识以及第三RRC消息的适配层中携带的标识均属于相同的终端设备101，因此可获知第一通道以及第二通道均连接至终端设备101。
再比如，终端设备101可在通过第二通道向第二接入设备103发送的第三RRC消息中携带终端设备101在第二制式的标识，第二接入设备103在接收第三RRC消息后，若根据以上对应关系确定终端设备101在第二制式的标识与自身存储的终端设备101的第一标识对应的终端设备101在第二制式的标识一致，则可获知第一通道以及第二通道均连接至终端设备101。
如图5所示，若第一接入设备102在第二制式的标识来自于第二接入设备103，本申请实施例提供的一种通信方法可包括以下步骤：
S301：第一接入设备102向第二接入设备103发送第一接入设备102在第一制式的标识以及第一接入设备102在第二制式的标识，所述第一接入设备在第一制式的标识和所述第一接入设备在第二制式的标识存在对应关系。
相应地，第二接入设备103接收第一接入设备102在第一制式的标识以及第一接入设备102在第二制式的标识。
S302：终端设备101在第一制式下建立与第一接入设备102之间的第一通道，所述第一通道承载于第一无线接口，所述第一无线接口的制式为第一制式。
S303：终端设备101通过第一通道向第一接入设备102发送RRC请求消息，RRC请求消息用于请求建立终端设备101与第二接入设备103之间的端到端的RRC连接。
相应地，第一接入设备102接收终端设备101通过第一通道发送的RRC请求消息。
S304：第一接入设备102向第二接入设备103发送RRC请求消息，并通知第二接入设备所述终端设备101在第一制式下的标识和/或第一通道对应的第一无线接口的信息。
S305：第二接入设备103接收RRC请求消息，获得终端设备101在第一制式下的标识和/或第一通道对应的第一无线接口的信息。
S306：第二接入设备103通过第一接入设备102，向终端设备101发送第二RRC消息第二RRC消息中携带第二接入设备103为终端设备101分配的第一标识，如C-RNTI。

S312：第二接入设备103接收第三RRC消息，获得第二接入设备103为终端设备101分配的第一标识、终端设备101在第二制式下的标识和/或第二通道对应的第二无线接口的信息的对应关系，确定终端设备101通过第一通道以及第二通道连接至第一接入设备102。
本申请中，第二接入设备103还可存储第一通道以及第二通道的对应关系，例如，存储第一通道的标识以及第二通道的标识的对应关系。其中，若网络制式为wifi制式，其对应的通道标识可以是wifi接入类别(access class，AC)标识等；若网络制式为SL制式，其对应的通道标识可包括SL逻辑信道标识(logic channel identifier，LCID)等。

例如，发送第二接入设备103与第一接入设备102之间的通道的标识、第一通道的标识以及第二通道的标识之间的对应关系。其中，第二接入设备103与第一接入设备102之间的通道的标识可以是DRB ID或LCID。可通过第一制式的信息表示第一通道，通过第二制式的信息表示第二通道，以及通过第二接入设备103与第一接入设备102之间的通道的标识信息表示该通道，例如，发送第一制式的信息、第一通道的标识、第二制式的信息、第二通道的标识以及第二接入设备103与第一接入设备102之间的通道的标识。

>>>RAT list(表示第一接入设备102与终端设备101之间的通道及通道各自的制式，第一接入设备102与终端设备101之间的通道可能包括第一通道以及第二通道)

在一种可能的示例中，第二接入设备103可向终端设备101发送配置消息，配置消息中包可能包含以下至少一项：QoS流(QoSflow)标识，第一通道标识，第二通道标识，终端设备和第二接入设备之间的通道标识(例如DRB ID)。上述三者之间存在映射关系。此外，终端设备101还可接收来自于核心网的非接入层(non-access ctratum，NAS)消息，NAS消息中可包含QoS flow标识以及对应的QoS参数。以便于终端设备根据所述QoS参数和QoS slow标识，确定上行数据包所对应的QoS flow标识。接着根据QoS flow标识和第一通道和或第二通道的映射关系，确定QoS flow标识对应的第一通道或第二通道的标识。从而终端设备101可以将上行数据包映射到QoS flow标识对应的第一通道或第二通道上。
示例性的，第二接入设备103可给终端设备101发送如下配置信息：
>DRB列表
>>DRB ID(表示终端设备101和第二接入设备103之间的通道标识)

或者，在终端设备101进行上行发送时，可由终端设备101从第一通道和第二通道中进行自主选择以确定使用哪个通道进行上行数据包的发送。在另外的示例中，也可由第二接入设备103通过调度信息指示终端设备101上行发送所采用的通道(该通道为第一通道或第二通道中的一个)，例如在下行控制信息(downlink control information，DCI)中增加通道指示，通道指示例如，“0”表示第一通道，“1”表示第二通道；通道指示也可能是制式信息，如wifi或者SL等，分别表示通过该制式对应的通道进行上行发射。
此外，可由第二接入设备103配置选择条件，由终端设备103根据选择条件从第一通道和第二通道中进行选择。示例性的，第二接入设备103可通过第一接入设备102向终端设备101发送第一通道对应的信号强度门限以及第二通道对应的信号强度门限。当第一通道的信号强度小于第一通道对应的信号强度门限时，终端设备101会选择第二通道进行上行发送；和/或，当第二通道的信号强度小于第二通道对应的信号强度门限时，终端设备101会选择第一通道进行上行发送。或者当第一通道的信号强度大于第一通道对应的信号强度门限时，终端设备101会选择第一通道进行上行发送；当第二通道的信号强度大于第二通道对应的信号强度门限时，终端设备101会选择第二通道进行上行发送。当上述两个条件都满足时，终端设备101可以任意选择一个通道进行上行发送，或者同时通过两个通道进行上行发送。例如终端设备101可以将数据包1通过第一通道发送，将数据包2通过第二通道发送。或者终端设备101可以将数据包进行复制后，一份通过第一通道发送，另一份通过第二通道发送。
在通过图1所示架构由第二接入设备103向终端设备101进行下行发送时，可由第二接入设备103或第一接入设备102决定通过第一通道还是第二通道进行下行发送。
在一种可能的示例中，可由第二接入设备103决定下行发送采用的通道，例如，第一种可能的方法为：第二接入设备103可在每个数据包中携带指示信息，用于指示向终端设备101传输所采用的通道。具体的，该指示信息可包括第一通道的标识或第一无线接口的信息(如第一制式的信息)以指示通过第一通道向终端设备101发送该数据包；或者，该指示信息可包括第二通道的标识或第二无线接口的信息(如第二制式的信息)以指示通过第一通道向终端设备101发送该数据包。或者第二种可能的方法为：第二接入设备103可在某个数据包中携带第一指示，用于指示向终端设备101传输所采用的通道(例如指示第一通道，或指示第一通道的制式)。之后第二接入设备103可能在某一个数据包中携带第二指示，第二指示不同于第一指示，例如第二指示用于指示第二通道或指示第二通道的制式。那么第一接入网设备在收到第一指示和第二指示期间，收到的来自第二接入设备103的数据包都通过第一通道发往终端设备101。第一接入网设备在收到第二指示后，收到的来自第二接入设备103的数据包都通过第二通道发往终端设备101，直到收到第三指示再改变通道。或者第三种可能的方法为：第二接入设备103可以通过RRC消息指示第一接入设备102，第二接入设备103和第一接入设备102之间的哪个DRB(DRB ID)的数据通过第一接入设备102和终端设备101之间的哪个通道(通道标识或者制式信息，通道标识)传输，例如RRC消息中可以包含DRB ID以及wifi指示，即告知第一接入设备102来自于DRB ID的数据通过wifi制式的通道发送给终端设备。或者RRC消息中可以包含DRB ID以及通道标识，例如假设通道标识0表示第一通道为wifi制式，通道标识1表示第二通道为LTE SL制式等。例如第二接入设备103先在RRC消息(为简便说明，该RRC消息可称为第一条RRC消息)中指示第一设备102通过第一通道进行下行数据发送，以及第二 接入设备103后在RRC消息(为简便说明，该RRC消息可称为第二条RRC消息)中指示第一设备102通过第二通道进行下行数据发送，则接收端设备在接收到这第一条RRC消息之后和接收到第二条RRC消息之前接收的来自于第二接入设备103的下行数据包均通过第一通道发送给终端设备101，在收到第二条RRC消息后，来自于第二接入设备103的下行数据包通过第二通道发送给终端设备101。
在另一种可能的示例中，对于配置有PDCP复制(PDCP duplication)的情形，第二接入设备103可在向第一接入设备102发送用于指示PDCP duplication开始(start)的指示信息，第一接入设备102可在收到该指示信息后执行下行数据包的复制，并通过第一通道以及第二通道分别发送复制的数据包。第二接入设备103还可向第一接入设备102发送用于指示PDCP duplication停止(stop)的指示信息，则第一接入设备102不再通过第一通道以及第二通道分别发送复制的数据包。此时，第二接入设备103可以参照前面介绍的三种可能的方法中的任意方法指示第一接入设备102向终端设备101传输该数据包所采用的通道。
此外，也可由第一接入设备102根据第一通道和第二通道的空口情况，决定通过第一通道还是第二通道进行下行发送。

此后，终端设备101可在建立S403所述的第四通道的过程中，向第二接入设备103发送该第二标识，从而令第二接入设备103获知通过第三通道以及第一接入设备102与第二接入设备103之间的连接接入的终端设备，与通过第四通道接入的终端设备均为终端设备101。示例性的，在S403的实施中，终端设备101可通过第四通道向第二接入设备103发送第六RRC消息，该第六RRC消息中可携带该第二标识。从而令第二接入设备103获知通过第四通道接入的终端设备与通过第三通道以及第一接入设备102与第二接入设备103之间的连接接入的终端设备均为同一个终端设备101。
方式二：

当终端设备101使用该特定的RACH资源请求接入第二接入设备103(即请求建立所述第四通道)时，第二接入设备103即可识别通过第三通道以及第一接入设备102与第二接入设备103之间的连接接入的终端设备，与通过第四通道接入的终端设备均为终端设备101。
在根据以上方法一和/或方法二识别通过第三通道以及第一接入设备102与第二接入设备103之间的连接接入的终端设备，与通过第四通道接入的终端设备均为终端设备101之后，第二接入设备103可存储第三通道以及第四通道之间的对应关系，例如，存储第三通道的标识以及第四通道的标识之间的对应关系。
示例性的，第二接入设备103可通过信令(例如第八RRC消息)向终端设备101指示第三通道以及第四通道之间的对应关系，从而令终端设备101选择向第二接入设备103进行上行发送和所采用的路径。例如，在第八RRC消息中携带第三通道的标识以及第四通道的标识，第三通道标识比如wifi AC或者SL LCID，第四通道的标识比如DRB ID或LCID。可选地，在第八RRC消息中可以携带QoS flow标识、第三通道的标识以及第四通道的标识，以表示上述三者存在对应关系。从而令终端设备101知道将具有某个QoS flow的上行数据包送往QoS flow对应的第三通道或第四通道发送。至于上行数据包具体通过第三通道或第四通道中的哪个通道发送，可以参考前面实施例中介绍的方法确定。
