下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的技术方案进行详细地说明。
如图2所示，为本申请一示例性实施例提供的路径切换的方法200的流程示意图，所述方法200可以由第一终端执行，例如，可以由安装于所述第一终端中的硬件和/或软件执行，所述方法200包括如下步骤。
S210，在满足第一条件的情况下，在至少两个路径之间进行切换。
其中，所述第一条件包括以下(1)-(5)中至少一项。
(1)所述第一终端接收到网络侧设备发送的路径切换指示。
其中，所述路径切换指示用于指示所述第一终端在所述至少两个路径之间进行切换。本实施例中，所述路径切换指示可以是所述网络侧设备基于所述第一终端上报的路径传输参数确定，也可以是根据预配置的协议等确定。在所述路径切换指示可以是所述网络侧设备基于所述第一终端上报的路径传输参数确定的情况下，如果所述传输参数指示所述第一终端的当前路径对应的连接不稳定，那么，所述网络侧设备可以发送所述路径切换指示给所述第一终端，以指示所述第一终端进行路径切换，可以理解，所述目标路径为所述至少两个路径中的一个。
(2)所述第一终端发送路径切换请求给所述网络侧设备，所述路径切换请求用于向所述网络侧设备请求所述第一终端在所述至少两个路径之间进行切换。
其中，所述路径切换请求中可以包括一个或多个信息，例如，作为一种 可能的实现方式，所述路径切换请求中可以包括以下(2a)-(2i)中的至少一项。

(2c)所述目标路径对应的目标网络的标识。
其中，所述目标网络可以是所述第一终端与所述第二终端或所述第一终端与所述网络侧设备之间的网络，如Wifi网络、蓝牙网络、旁链路(Sidelink)网络、UU网络等，在此不做限制。
(2d)发起路径切换的目标链路。
其中，所述目标链路可以是下行链路(Downlink)、上行链路(Uplink)、旁链路等。
(2e)所述目标路径。
其中，所述目标路径可以为所述至少两个路径中的一个，具体可由所述第一终端确定，例如，所述目标路径可以是所述终端根据路径的通信质量等传输参数确定，也可以由所述网络侧设备和所述第一终端预先约定，还可以是通过协议规定，在此不做限制。
(2f)发起路径切换的原因。
其中，所述发起路径切换的原因可以包括人体辐射限制(Maximum Permissible Exposure，MPE/Specific Absorption Rate，SAR)、终端功耗受限、网络覆盖受限、网络吞吐量受限、信号质量、电池电量不足等，本实施例对此不做限制。
例如，如果所述第一终端在通信过程中，检测到人体辐射大于阈值，那么，所述第一终端可以发送路径切换请求给所述网络侧设备，以请求进行路 径的切换，从而确保所述第一终端以及与其通信的其他终端的通信质量。
(2h)所述路径切换请求的传输方式。
其中，所述路径切换请求通过媒体访问控制控制单元(Medium Access Control-Control Element，MACCE)、无限资源控制(Radio Resource Control，RRC)消息、上行控制信息(Uplink Control Information，UCI)消息、非接入层(NAS)消息或物理层信令(如调度请求(Scheduling Request，SR))等发送。
(2i)第一指示信息，用于指示上报所述路径切换请求是否经所述网络侧设备授权。
其中，所述网络侧设备授权可以包括：所述第一终端在发送路径切换请求之前，由第一网络节点(也即，网络侧设备)触发用户授权过程，获得允许上报的授权，或者第二网络节点(也即，网络侧设备)基于授权配置相应的模式，当所述第一终端处于模式下触发所述第一终端发送路径切换请求。可以理解，所述第一网络节点可以相同也可以不同，在此不做限制。
需要注意的，作为一种可能的实现方式，所述第一终端也可以在发送所述路径切换请求之前，发送第二终端的标识和/或目标网络标识给所述网络侧设备，以使得所述网络侧设备基于所述第二终端的标识和/或目标网络标识执行预定操作，如终端之间的关联等，进而基于关联后的终端进行路径切换等，由此，确保路径切换时的可靠性。
(3)对约定信号进行检测，所述约定信号为目标路径对应的信号，所述目标路径为所述至少两个路径中的一个。

可选地，所述信号检测结果可以包括参考信号接收功率(Reference Signal Received Power，RSRP)、干扰信息、信号与干扰加噪声比(signal-to-noise and interference ratio，SINR)、信道质量指示(Channel quality indicator，CQI)等，所述干扰信息可以是其他终端或设备对所述第一终端造成的干扰的相关信息。
所述预定义条件可以是由所述网络侧设备与所述第一终端协商约定，也可以是协议约定等。本实施例中，根据所述信号检测结果的不同，所述预定义条件可以不同，例如，所述预定义条件可以基于参考信号接收功率、干扰信息、信号与干扰加噪声比等进行设定，在此不做限制。
应注意，对于前述的(2)和(4)，所述第一终端可以在发送所述路径切换请求或信号检测结果后，在本地直接进行路径切换，也可以是在接收到所述网络侧设备反馈的响应信息后，再进行路径切换，本实施例对此不做限制。
此外，所述目标路径可以由终端和所述网络侧设备协商确定，也可以由所述网络侧设备预先配置，还可以由协议规定，在此不做限制。
需要说明的是，本实施例中所述的网络侧设备可以是核心网或基站等。所述第一终端或/和所述第二终端可以是手机、智能眼镜、智能耳机、智能手表等，除此之外，所述网络侧设备、所述第一终端、所述第二终端还可以参照对前述无线通信***中的终端和网络侧设备的相关介绍，为避免重复，在此不再赘述。
在本实施例中，所述第一终端在接收到网络侧设备发送的路径切换指示、或者发送路径切换请求给所述网络侧设备、或者上报信号检测结果的情况下，在至少两个路径之间进行切换，由此，能够实现路径之间的有效切换，解决由于终端与终端之间或终端与网络侧设备之间的连接不稳定，而影响通信质量的问题。
如图3所示，为本申请一示例性实施例提供的路径切换的方法300的流 程示意图，所述方法300可以由第一终端执行，例如，可以由安装于所述第一终端中的硬件和/或软件件执行，所述方法300包括如下步骤。
S310，在满足第一条件的情况下，在至少两个路径之间进行切换。
其中，S310的实现过程除了可以参照方法200中的相关描述以外，作为本实施例的一种可能的实现方式，所述至少两个路径可以包括以下(1)-(9)任一项所述的路径。
(1)第一路径，用于所述第一终端向与第二终端传输数据。
在此情况下，所述第一终端与所述第二终端之间可以通过Wifi、蓝牙、旁链路等直接连接，以实现数据传输。
(2)第二路径，用于所述第一终端通过所述网络侧设备向所述第二终端传输数据。
在此情况下，所述第一终端与所述第二终端之间是通过所述网络侧设备连接，如UU连接等。
一种可能的实现方式中，在所述第一终端切换至所述第二路径的情况下，所述第一终端还可以执行以下(2a)或(2b)中至少一项，以适应上行业务或下行业务在不同的路径间的动态切换场景。
(2a)监听下行调度业务，以及根据所述下行调度业务对应的指定信息确定是否需要接收和/或转发所述下行调度业务。
其中，所述指定信息可以包括下行控制信息(Downlink Control Information，DCI)中的无线网络临时标识(Radio Network Temporary Identifier，RNTI)、专用DCI域指示、特定比特组合中的至少一个。
可选的，所述特定比特组合为资源分配、混合自动重传请求(Hybrid automatic repeat request，HARQ)进程(process)等域中所指示值的特定组合等，在此不做限制。
(2b)监听上行业务，以及根据预定规则确定是否需要发送和/或转发所述上行业务。
其中，所述预定规则可以是基于发送比特数的大小、剩余功率余量的大小等确定，例如，在所述发送比特数大于阈值时，所述第一终端发送所述上行业务，在所述在发送比特数不大于阈值时，所述第一终端转发所述上行业务等，在此不做限制。
另外，所述预定规则可以是由所述网络侧设备与所述第一终端协商确定，也可以是由所述网络侧设备配置或协议预定。
另一种可能的实现方式中，在所述第一终端切换至所述第二路径，如果所述第一终端与所述第二终端位于预定组(group)的情况下，或者，所述网络侧设备通过(单点到多点(Single Cell Point To Multipoint，SC-PTM)方式发送DCI消息，所述第一终端可以监听所述网络侧设备发送给所述第二终端的DCI消息，进而根据所述DCI消息确定是否进行路径切换、是否进行业务数据的转发/接收等，具体可根据所述DCI消息执行。
(3)第三路径，用于将所述第一终端对应的上行传输由所述第二终端代理。
在此情况下，是将所述第一终端对应的上行传输和下行传输分离开，也即是，本实施例定义了终端在不同的路径间进行上行分离传输，由此，可进一步提供路径切换时的灵活性，确保通信质量。
一种可能的实现方式中，在所述第一终端对应的第一上行信道满足第二条件的情况下，将所述第一终端对应的第一上行信道由所述第二终端代理。其中，所述第一上行信道可以包括物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)、物理随机接入信道(Physical Random Access Channel，PRACH)、探测参考信号(Sounding Reference Signal，SRS)中的至少一个。
本实施例中，为了确保所述网络侧设备和所述第一终端对代理条件(也即第二条件)具有统一的理解，所述第一终端可以发送第一信息给所述网络侧设备，所述第一信息包括用于将所述第一终端对应的第一上行信道由所述 第二终端代理的代理时的第二条件。一种可能的实现方式，所述第二条件可以包括以下(3a)-(3e)中的至少之一。
(3a)发送比特数大于第一预定值。
(3b)功率余量报告(Power Headroom Report，PHR)小于第二预定值。
其中，在前述(1)和(2)中，所述第一预定值和所述第二预定值可以由网络侧设备配置，也可以由协议规定，在此不做限制。
(3c)发送特定承载对应的信息。
(3d)发送特定逻辑信道对应的信息。
其中，前述(3c)和(3d)中所述的特定承载和特定逻辑信道可以由网络侧设备配置，也可以由协议规定，在此不做限制，其中，所述特定逻辑信道可以包括PUSCH、PUCCH等。
(3e)承载有UCI。
可以理解，所述第二条件可以包括但不限于前述(3a)-(3e)中所述，例如，作为一种实现方式，所述第一终端还可以上报对应的上行限定，在此情况下，如果所述网络侧设备的调度超过了对应的上行限定，则触发相应的代理过程。
需要注意，在所述第一终端对应的第一上行信道被所述第二终端代理的情况下，所述第一上行信道对应的指定参数的取值相比于由所述第一终端发送增加了第三预定值(如delta)，所述指定参数为K1和K2中的最小值。
可以理解，在前述方案的实现过程中，所述第一终端需上报所述的第三预定值给所述网络侧设备，使得网络侧设备的调度满足K1/K2中的最小值+第三预定值(delta)对应的限制。由此，在网络侧设备按照正常的K1/K2调度PUSCH或PUCCH等的情况下，如果是所述第二终端直接发送，则所述第二终端按照K1/K2发送；如果是由所述第一终端代理发送，则按照接收到的K1/K2值增加Delta进行发送。
相应的，在所述第一终端代理第二终端发送第二上行信道的情况下，所 述第二上行信道对应的指定参数的取值相比于由所述第二终端发送增加了第三预定值，所述指定参数为K1和K2中的最小值。
前述实现方案中，如果所述第一终端的上行信道由所述第二终端代理的情况下，那么，可以是所述第一终端的全部上行传输或部分上行传输被所述第二终端代理，在此不做限定。
(4)第四路径，包括所述第一路径和所述第二路径，其中，在同时保持所述第一路径和所述第二路径的情况下，所述第一路径对应的连接或所述第二路径对应的连接处于挂起(Suspend)状态。
在此情况下，如果第一终端与所述第二终端之间同时保持由UU连接和旁链路连接，那么，所述UU连接和所述旁链路之间有一个处于suspend状态。
(5)第五路径，用于所述第一终端向所述网络侧设备传输数据。
其中，与前述第二路径不同的是，所述第五路径中，所述第一终端向所述网络侧设备传输的数据可以不传输给所述第二终端，但在所述第二路径中，所述第一终端向所述网络侧设备传输的数据需要传输给所述第二终端。
一种可能的实现方式中，与前述第二路径类似，在所述第一终端切换至所述第五路径，如果所述第一终端与所述第二终端位于预定组(group)的情况下，或者，所述网络侧设备通过SC-PTM方式发送DCI消息，所述第一终端可以监听所述网络侧设备发送给所述第二终端的DCI消息，进而根据所述DCI消息确定是否进行路径切换、是否进行业务数据的转发/接收等，具体可根据所述DCI消息执行。
(6)第六路径，用于所述第一终端通过所述第二终端向所述网络侧设备传输数据。
其中，与前述第一路径不同的是，在所述第六路径中，所述第二终端需要将第一终端发送的数据传输给所述网络侧设备，而在所述第一路径中，所述第二终端可以不将所述第一终端发送的数据传输给所述网络侧设备。
(7)第七路径，用于所述第一终端将第二终端的数据转发至所述网络侧设。
(8)第八路径，用于所述第一终端代理所述第二终端的上行传输。
(9)第九路径，是将指定路径中的所述第一终端和所述第二终端调换顺序后得到的路径，所述指定路径为所述第一路径至所述第八路径中的一个。
例如，以所述指定路径为所述第一路径为例，所述第九路径，用于所述第二终端向与第一终端传输数据。例如，以所述指定路径为所述第二路径为例，那么，所述第九路径，用于所述第二终端通过所述网络侧设备向所述第一终端传输数据。
作为一种可能的实现方式，在前述给出的第一路径至第九路径的基础上，请再次参阅图3，S310的实现过程可以包括S311和S312，内容如下。
S311，在满足第一条件的情况下，根据所述第一终端和所述第二终端是否处于不同的小区，确定目标路径。
示例性的，如果所述第一终端和所述第二终端位于相同的小区，那么，所述第一终端和所述第二终端可以正常适用前述的各种路径；但是，如果所述第一终端处于小区1，而所述第二终端从小区1切换到了小区2，那么，前述的第六路径就不适用所述第一终端的路径切换场景。
本实施例中，根据所述通信场景以及传输参数的不同，所述目标路径可以是所述第一路径至所述第六路径中的一个。
S312，切换至所述目标路径。
其中，如果所述第一终端和所述第二终端可以正常适用前述的各种路径，那么，所述第一终端可以由当前路径切换至所述目标路径，也可以是直接开启所述目标路径，在此不做限制。
进一步，为了实现路径的顺利切换，所述第一终端还可以发送第二信息给所述网络侧设备。其中，所述第二信息包括以下(1)-(4)中至少一项。
(1)所述第一终端与第二终端之间的关联关系；例如，所述关联关系可 以是第一终端与所述第二终端是否具有相同的承载、是否位于同一小区、是否绑定在一起等，在此不做限制。
本实施例中，对于具有关联关系的所述第一终端和所述第二终端，在进行路径切换时，可以同步发起路径切换。应注意，考虑到，由于切换时机的不同可能导致所述第一终端、所述第二终端与不同小区连接的问题，对此，本实施例中给出如下(1a)、(1b)所示的两种解决方案。
(1a)所述第一终端可以根据其与第二终端是否处于不同的小区确定是直接向小区发送，还是通过转发至第二终端后再发送至网络侧设备的方式发送。
在此情况下，如果第一终端和所述第二终端各自向相应的小区发送相关信息，那么，所述第一终端与所述第二终端之间的连接处于不可用状态。
(1b)节点间协调确定转发关系。
例如，对于下行调度业务，所述第一终端位于小区1，所述第二终端位于小区2，到达小区1的业务先转送至小区2，再从小区2发送至第二终端，最后再从第二终端发送至第一终端；或者在预先定义的切换场景下，第一终端/基站(gNB)向网络侧设备(核心网)上报相应的关联关系及所属小区关系，核心网根据第一终端和第二终端之间的关联关系及所属小区的关系，将数据包发送至对应的小区。
又例如，对于上行业务，gNB仍然可以将相应的信息进行类似(1b)中所述的转发，在此不再赘述。
(2)所述第一终端与第二终端之间实现所述关联关系时，所采用的网络关联方式；其中，所述网络关联方式包括Wifi、蓝牙、旁链路、UU链路中的任意一种。
(3)标识信息，所述标识信息为所述网络关联方式对应的网络的标识和/或网络设备的标识。
(4)所述目标路径对应的第一测量量。其中，所述第一测量量可以包括 但不限于RSRP、干扰情况、SINR、CQI等。
相应的，所述网络侧设备可基于接收到的所述第二信息，确定测量配置信息，并发送所述测量配置信息给所述第一终端，使得所述第一终端基于所述测量配置信息测量得到测量结果，进而上报所述测量结果给所述网络侧设备，其中，所述测量配置信息可以包括网络标识信息和/或第二测量量，所述第二测量量与所述第一测量量可以相同，也可以不同。
可选地，所述第一终端上报测量结果可以包括以下(4a)-(4d)中至少一项。
(4a)通过层1上的UCI上报所述测量结果。
(4b)通过层2上的MAC CE上报所述测量结果。
(4c)通过层3上的RRC上报所述测量结果。
(4d)通过NAS消息上报所述测量结果。
可以理解，在本实施例中，所述网络侧设备发送的路径切换指示可以是所述网络侧设备基于所述测量结果确定。
进一步，本申请实施例给出的路径切换的方法中，所述网络侧设备在发送路径切换指示、接收到路径切换请求、或信号检测结果后，可以配置和/或激活目标路径，所述目标路径为所述路径切换指示、所述路径切换请求或所述信号检测结果对应的路径。
可选地，所述网络侧设备在配置和/或激活目标路径时，可以包括以下(1)-(4)至少一项。
(1)将所述第一终端与第二终端进行关联，以及在所述第一终端以及所述第二终端对应的网络节点间传递关联信息。
例如，所述第一终端可以将自身以及第二终端的RNTI信息直接发送给所述网络侧设备，由所述网络侧设备基于所述RNTI信息对所述第一终端与第二终端进行关联，本实施例中，所述“关联”也可以理解为绑定等。
