其中，上述的网络设备01可以为基站、发射接收节点(transmission and reception point，TRP)或无线访问接入点(wireless access point，AP)等。网络设备01可以是全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)网络中的基站收发信台(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的NB(NodeB)，还可以是LTE中的eNB或eNodeB(evolutional NodeB)。网络设备01还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器。网络设备01还可以是5G通信系统中的节点或未来演进网络中的节点。网络设备01还可以是无线局域网中的无线访问接入点。然用词并不构成对本公开的限制。
终端设备11-终端设备13可以为无线终端设备也可以为有线终端设备，该无线终端设备可以是指向用户提供语音和/或其他业务数据连通性的设备，具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G 网络中的终端设备或者未来演进的PLMN网络中的终端设备等。无线终端设备可以经无线接入网(radio access network，RAN)与一个或多个核心网进行通信，无线终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话)和具有移动功能的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据，以及个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)等设备，无线终端设备也可以为移动设备、用户设备(user equipment，UE)、接入终端设备、无线通信设备、终端设备单元、终端设备站、移动站(mobile station)、移动台(mobile)、远程站(remote station)、远方站、远程终端设备(remote terminal)、订户单元(subscriber unit)、订户站(subscriber station)、用户代理(user agent)、终端设备装置等。作为一种实例，在本公开实施例中，图1以终端设备11，终端设备12，终端设备13是手机为例示出。
相关技术中，终端设备与网络设备之间仅可以通过一种通信方式进行数据传输，例如，终端设备通过无线局域网与网络设备进行数据传输，或者，终端设备可以通过蜂窝网络与网络设备进行数据传输。当终端设备所连接的网络信号的信号质量较差时，会大大降低数据传输的速率，进而可能导致数据传输失败。本公开实施例提供的数据传输方法，是在终端设备与M个网络设备之间存在N条传输链路的情况下(即本公开实施例提供的方案支持终端设备与网络设备之间进行多传输链路并行传输数据)，从N条传输链路中选择至少一条传输链路用于传输目标数据。从而可以避免只有一条传输链路且该传输链路的信号质量较差时，数据传输速率较低的问题。
下面结合附图，通过具体的实施例及其应用场景对本公开实施例提供的一种数据传输方法及终端设备进行详细地说明。
参考图2所示，应用于第一终端设备，本公开实施例提供了一种数据传输方法，该方法可以包括下述的步骤201和步骤202。
步骤201、在第一终端设备与M个网络设备间建立有N条传输链路的情况下，第一终端设备从N条传输链路中，确定目标传输链路。
其中，目标传输链路为N条传输链路中的至少一条(本公开实施例不限定目标传输链路的数量，具体可以根据实际使用需求确定)；任意一条传输链路为：第一传输链路或第二传输链路，第一传输链路为第一终端设备与一个网络设备间建立的传输链路，第二传输链路为第一终端设备通过一个第二终端设备与一个网络设备间建立的传输链路，N为大于1的整数，M为小于或等于N的正整数。
本公开实施例中，M个网络设备可以均是基站，则第一终端设备或第二终端设备与基站间通过蜂窝网络进行数据传输。M个网络设备也可以均是无线访问接入点，则第一终端设备或第二终端设备与无线访问接入点间通过无线局域网等进行数据传输。M个网络设备可以部分是基站，部分是无线访问接入点，则第一终端设备和第二终端设备中的，一部分终端设备与基站间进行数据传输，另一部分终端设备与无线访问接入点间进行数据传输。M个网络设备还可以是其他的设备，具体可以根据实际使用需求确定，本公开实施例不作限定。
当M等于1时，第一终端设备与同一个网络设备直接建立一条传输链路，以及间接建 立(N-1)条传输链路，或者，第一终端设备与同一个网络设备间接建立N条传输链路。
当M大于1时，与第一终端设备直接建立传输链路的网络设备和与第一终端设备间接建立传输链路的网络设备可以相同，也可以不相同，具体可以根据实际使用情况确定，本公开实施例不作限定。
可以理解，目标传输链路可以为N条传输链路中的一条或多条传输链路。N条传输链路中的每条传输链路为下述任意一项：第一终端设备与一个网络设备间建立的传输链路(第一传输链路)，第一终端设备通过一个第二终端设备与一个网络设备间建立的传输链路(第二传输链路)。
本公开实施例中，一条第二传输链路具体包括：第一终端设备与一个第二终端设备间建立的传输链路(以下称为第三传输链路)和该一个第二终端设备与一个网络设备间建立的传输链路(以下称为第四传输链路)。例如，如图1所示，一条第二传输链路包括：终端设备11与终端设备12间建立的传输链路(第三传输链路)和终端设备12和网络设备01间建立的传输链路(第四传输链路)。其中，建立第三传输链路的两个终端设备之间进行设备到设备(device-to-device，简称D2D)通信，建立第四传输链路的终端设备和网络设备之间进行网络通信(例如，蜂窝网络、无线局域网络等，本公开实施例不作限定)。
需要说明的是，本公开实施例中，D2D通信是基于蜂窝网络的设备到设备通信，即终端设备之间可以不经网络设备(通常为基站)中转而直接进行数据传输。
需要说明的是，通常情况下，一个终端设备至多建立一条第一传输链路，可以建立多条第二传输链路。但本公开不限定第一终端设备建立多少条第一传输链路(在第一终端设备中设置多个用于建立第一传输链路的模块，则可以同时建立多条第一传输链路)，也不限定第一终端设备建立多少条第二传输链路，具体可以根据实际使用需求确定，本公开实施例不作限定。
可选地，N条传输链路包括一条第一传输链路和(N-1)条第二传输链路，或者，N条传输链路包括N条第二传输链路。其中，第一传输链路为第一终端设备与一个网络设备间的传输链路，每条第二传输链路为第一终端设备通过一个第二终端设备与一个网络设备间的传输链路。
下面具体介绍该N条传输链路的上述两种可能的情况。
第一种可能的情况，N条传输链路包括一条第一传输链路和(N-1)条第二传输链路。
其中，(N-1)条第二传输链路，具体为第一终端设备分别通过(N-1)个第二终端设备与目标网络设备间建立的传输链路。建立第二传输链路的目标网络设备可以全部相同，也可以部分相同，也可以全部不同，具体可以根据实际使用需求确定，本公开实施例不作限定。
示例性的，当M等于1时，则M个网络设备为一个目标网络设备。该第一终端设备和(N-1)第二终端设备均与同一个目标网络设备间建立传输链路。第一传输链路为第一终端设备与该一个目标网络设备间建立的传输链路，每个第二传输链路为第一终端设备通过一个第二终端设备与该一个目标网络设备间建立的传输链路。例如，如图1所示，终端设备11与网络设备01间建立第一传输链路，终端设备11通过终端设备12与网络设备01间建立第二传输链路，终端设备11通过终端设备13与网络设备01间建立第二传输链路。
示例性的，当M大于1时，第一传输链路为第一终端设备与第二网络设备间建立的传 输链路，建立一条第二传输链路的目标网络设备可以为M个网络设备中的任意一个，也可以为除第二网络设备之外的任意一个，具体可以根据实际使用需求确定，本公开实施例不作限定。例如，如图3所示，终端设备11与网络设备01间建立第一传输链路，终端设备11通过终端设备14与网络设备02间建立第二传输链路，终端设备11通过终端设备15与网络设备03间建立第二传输链路。其中，终端设备11还可以通过终端设备15与网络设备02间建立第二传输链路，或者，终端设备11还可以通过终端设备15与网络设备01间建立第二传输链路。
第二种可能的情况，N条传输链路包括N条第二传输链路。即该N条传输链路均为第一终端设备与M个网络设备间的间接传输链路。
其中，N条第二传输链路，具体为第一终端设备分别通过N个第二终端设备与目标网络设备间建立的传输链路。建立第二传输链路的目标网络设备可以全部相同，也可以部分相同，也可以全部不同，具体可以根据实际使用需求确定，本公开实施例不作限定。
示例性的，当M等于1时，建立第二传输链路的目标网络设备全部相同。
示例性的，当M大于1时，建立第二传输链路的目标网络设备可以部分相同，也可以全部不同。例如，如图4所示，终端设备11通过终端设备14与网络设备02间建立第二传输链路，终端设备11通过终端设备15与网络设备01间建立第二传输链路。
需要说明的是，本公开实施例不针对第一终端设备建立两条以上第一传输链路的方案进行详细描述，具体可以参考上述对第一种可能的情况和第二种可能的情况的相关描述。
目前，D2D通信的发现方案包括：公开发现与限制发现两种。其中，对于限制发现，终端设备在没有明确许可的情况下是不允许被检测到的，即终端设备禁止与陌生的终端设备进行通信连接，从而可以保证终端设备的隐私性与安全性。而对于公开发现，只需当前终端设备是另一个终端设备的近邻设备，则可能被检测到，并且进行D2D通信连接，相较于限制发现，这种公开发现模式隐私性较差，但是连接复杂度更低。本公开实施例不限定建立D2D通信的两个终端设备的发现过程是公开发现，还是限制发现，具体可以根据实际使用需求确定。
可选地，一个第二终端设备的一个应用中包括第一标识，第一标识用于指示第一终端设备的用户。即第一终端设备的用户和每个第二终端设备的用户之间为基于一个应用的好友关系。即建立D2D通信的两个终端设备的发现过程是限制发现。
其中，第一终端设备的用户和每个第二终端设备的用户之间可以是基于同一个应用的好友关系，也可以是基于不同应用的好友关系，具体可以根据实际使用需求确定，本公开实施例不作限定。
示例性的，限制发现的限制条件为：第一终端设备和每个第二终端设备可以为即时社交应用中的好友或群好友，例如，QQ好友、QQ群好友、微信好友或微信群好友等。即终端设备可以设置只有为即时社交应用中的好友或群好友的终端设备，才可以检测到并与之进行D2D通信的发现与会话，这样可以保证终端设备的隐私性与安全性。另一方面，既是邻近设备，又是即时社交应用中的好友或群好友的两个终端设备的用户通常为长期一起生活或工作的新戚、朋友、同事等，因此相距都比较近，这样有利于简化D2D连接的算法，而且D2D连接信号较好，而且建立的D2D通信之间的干扰也较低。
可选地，该N条传输链路是第一终端设备和每个第二终端设备通过无线局域网与M 个网络设备间建立的传输链路。下面以无线局域网为无线保真(wireless-fidelity，WiFi)，网络设备为无线访问接入点为例进行详细说明，但本公开不限于此。相对于通过蜂窝网络(尤其第五代移动通信(5G)，研究表明，5G移动通信工作时比其他蜂窝网络通信(2G、3G和4G)工作时的耗电量大30％)建立的传输链路，通过这种方式建立的传输链路可以省流量、省电。
可选地，第一终端设备可以按照一定的规则，从该N条传输链路中选择传输速率较好的传输链路，作为目标传输链路。
示例性的，上述步骤201具体可以通过下述步骤201a实现。
步骤201a、第一终端设备按照预定规则，从N条传输链路中，确定目标传输链路。
其中，预定规则包括以下至少一项：传输链路的信号质量大于或等于预定阈值(记为第一项，其中，预定阈值的取值可以根据实际使用需求确定，本公开实施例不作限定)，传输链路处于空闲态(记为第二项，当前没有数据传输的传输链路处于空闲态)，传输链路对应的第一网络设备挂载终端设备的数量小于或等于第一网络设备挂载终端设备的负载能力(记为第三项)。
其中，信号质量较好、处于空闲态或对应的网络设备挂载终端设备的数量没有超过其挂载终端设备的负载能力的传输链路的数据传输速率相对较好。
可以理解，本公开实施例中，预定规则可以为上述第一项、第二项和第三项中的任意一项、任意两项或三项，预定规则还可以包括其他内容，例如，当预定规则至少包括第一项和第二项时，预定规则还可以包括第一项的优先级大于第二项的优先级；预定规则还可以包括终端设备与网络设备之间的直接连接为WiFi网络的优先级高于蜂窝网络的优先级等，具体可以根据实际使用需求确定，本公开实施例不作限定。
其中，建立D2D通信的终端设备间可以交互下述至少一项：终端设备与网络设备间建立的直接传输链路(第一传输链路或第四传输链路)的信号质量(例如，终端设备连接的WiFi信号的信号质量)，第一传输链路或第四传输链路是否处于空闲态，以及第一传输链路或第四传输链路对应的网络设备是否超过其挂载终端设备的负载能力(例如，第四传输链路对应的网络设备为WiFi设备，该WiFi设备是否超过其挂载终端设备的负载能力)。上述交互可以是实时交互，也可以是周期性的交互，本公开实施例不作限定。若为周期性交互，终端设备可以将交互内容存储在一个文本中，并周期性的更新该文本。
第一终端设备可以通过实时交互的方式或者读取文本的方式，获得每条第四传输链路的上述信息，并根据获得的信息，从N条传输链路中确定目标链路。
示例性的，第一终端设备可以将N条传输链路中，信号质量大于或等于预定阈值的传输链路中的至少一条确定为目标传输链路。
示例性的，第一终端设备可以将N条传输链路中，信号质量大于或等于预定阈值，且处于空闲态的传输链路中的至少一条确定为目标传输链路。
示例性的，第一终端设备可以将N条传输链路中，信号质量大于或等于预定阈值、处于空闲态、且对应的网络设备没有超过该网络设备挂载终端设备的负载能力的传输链路中的至少一条确定为目标传输链路。
本公开实施例提供了多种预定规则，第一终端设备可以根据实际需求选择对应的预定规则，从而可以更好的从N条传输链路中确定目标传输链路，进而可以更好的实现通过目 标传输链路传输目标数据。
可选地，目标传输链路对应的网络设备均为无线访问接入点。即上述预设规则还可以包括：第四项、传输链路为终端设备与无线访问接入点间的传输链路。
示例性的，第一终端设备可以将N条传输链路中，为终端设备与无线访问接入点间的传输链路中的至少一条确定为目标传输链路。
本公开实施例中，当目标传输链路为终端设备与无线访问接入点间的传输链路的情况下，可以节约流量，而且更省电。
可选地，当N条传输链路包括一条第一传输链路和N-1条第二传输链路时，N条传输链路中包括第一类传输链路和第二类传输链路，第一类传输链路为：传输链路对应的网络设备与第一传输链路对应的网络设备相同的传输链路，第二类传输链路为N条传输链路中除第一类传输链路之外的传输链路。第一终端设备优先从第一类传输链路中确定目标传输链路，在第一类传输链路中不存在目标传输链路的情况下，第一终端设备再从第二类传输链路中确定目标传输链路。
示例性的，当N条传输链路包括一条第一传输链路和N-1条第二传输链路时，上述步骤201a具体的可以通过下述的步骤201a1-步骤201a3实现。
步骤201a1、第一终端设备按照预设规则，判断第一类传输链路中是否存在目标传输链路。
在判断第一类传输链路中存在目标传输链路的情况下，执行下述步骤201a2，否则执行下述步骤201a2。
步骤201a2、第一终端设备按照预定规则，从N条传输链路中的第一类传输链路中，确定目标传输链路。
第一类传输链路为：传输链路对应的网络设备与第一传输链路对应的网络设备相同的传输链路。当N条传输链路包括一条第一传输链路和N-1条第二传输链路时，第一类传输链路中至少包括一条传输链路，即第一类传输链路至少包括第一传输链路，还可以包括至少一条第二传输链路(传输链路对应的网络设备与第一传输链路对应的网络设备相同的第二传输链路)。
步骤201a3、在第一类传输链路中不存在目标传输链路的情况下，第一终端设备按照预定规则，从第二类传输链路中确定目标传输链路。
第二类传输链路为N条传输链路中除第一类传输链路之外的传输链路，即第二类传输链路为传输链路对应的网络设备与第一传输链路对应的网络设备不相同的第二传输链路。
步骤202、第一终端设备通过目标传输链路传输目标数据。
当目标传输链路包括至少一条第二传输链路时，针对一条第二传输链路传输数据的过程可以为如下描述：第一终端设备向一个第二终端设备(以下记为第三终端设备)发送第一请求消息，第一请求消息用于请求该第三终端设备与第三网络设备(与第三终端设备建立第四传输链路的网络设备)传输第一数据，第一数据为目标数据中的数据。第三终端设备接收第一请求消息，并根据第一请求消息，与第三网络设备进行第一数据的传输(例如，第三终端设备接收到第一请求消息后，开通中转通道端口，为第一终端设备与第三网络设备间转发第一数据)。
本公开实施例中的数据传输包括下述至少一项：数据的上传和数据的下载。
需要说明的是，本公开实施例支持终端设备与WiFi之间进行多传输链路的并行数据传输。可以理解，通过一条传输链路进行数据传输为串行数据传输。
可选地，当目标传输链路为一条传输链路时，第一终端设备通过该一条传输链路传输目标数据。
可选地，当目标传输链路为多条传输链路时，第一终端设备通过该多条传输链路共同传输该目标数据(第一终端设备通过该多条传输链路进行并行数据传输)。
示例性的，在目标传输链路的链路数量大于1的情况下，上述步骤202具体的可以通过下述的步骤202a实现。
步骤202a、第一终端设备按照目标传输链路的链路数量以及目标数据的数据量，通过目标传输链路传输目标数据。
第一终端设备通过目标传输链路传输目标数据之前，先要根据目标传输链路的链路数量、目标数据的数据量以及分配原则对目标数据进行分配。
可选地，可以根据平均分配原则来分配目标数据，即将目标数据平均分配给目标传输链路中的每条传输链路来传输。也可以根据传输链路的信号质量比值来分配目标数据，即信号质量较好的传输链路分配到的数据较多，信号质量较差的传输链路分配到的数据较少。也可以根据传输链路是否处于空闲态来分配目标数据，即处于空闲态的传输链路分配到的数据较多，处于非空闲态的传输链路分配到的数据较少。还可以根据其他分配原则分配目标数据。本公开实施例中，分配原则可以为上述的一种或多种，具体可以根据实际使用需求确定，本公开实施例不作限定。
本公开实施例提供了多种分配原则，第一终端设备可以根据实际需求选择对应的分配原则，从而可以更好的实现通过目标传输链路传输目标数据。
本公开实施例提供的数据传输方法，尤其可以在第一终端设备所连接的N条传输链路中第一传输链路(例如，第一终端设备连接的WiFi或5G等)的网络信号较差，数据传输速率低，或没有第一传输链路(信号太差，传输链路断开)的情况下，第一终端设备可以从该N条传输链路中的多条第二传输链路中选择传输速度较快的至少一条传输链路，作为用于传输目标数据的目标链路，以提高数据传输速率，从而可以解决相关技术因数据传输速率低而出现卡顿现象或导致通信方式切换，甚至导致数据传输失败的问题。
示例性的，首先考虑终端设备通过无线局域网与无线访问接入点(即网络设备)间进行数据传输。如图1所示，终端设备11分别与终端设备12和终端设备13建立有D2D通信链路，终端设备11、终端设备12和终端设备13分别与同一无线访问接入点01(网络设备01)建立有WiFi通信链路(即通过WiFi网络进行连接)(即第一类传输链路)。对于终端设备11来说，其与无线访问接入点01间建立了3条传输链路，包括：一条第一传输链路和两条第二传输链路(以下将终端设备11与无线访问接入点01间的第一传输链路记为传输链路1，将终端设备11通过终端设备12与无线访问接入点01间的第二传输链路记为传输链路2，将终端设备11通过终端设备13与无线访问接入点01间的第二传输链路记为传输链路3)。其中，终端设备11、终端设备12和终端设备13均开启数据转发功能，该数据转发功能为一个终端设备为另一个终端设备(与该一个终端设备建立D2D通信的其他终端设备)与网络设备间的待传输数据的 转发功能(例如，终端设备12具有为终端设备11与无线访问接入点间的待传输数据的转发功能)。假设终端设备11需要进行数据传输时，可以通过传输链路1、传输链路2和传输链路3中的至少一条传输链路进行并行或串行数据传输。第一种情况，只要各终端设备在WiFi的覆盖范围之内，不管终端设备连接WiFi的信号弱与强，终端设备11均将传输链路1、传输链路2和传输链路3作为目标传输链路，这样终端设备11可以通过最快的传输速率传输数据，而不会出现数据卡死的现象(卡顿现象)。第二种情况，终端设备可以从传输链路1、传输链路2和传输链路3中选择传输速率较好的至少一条传输链路作为目标传输链路，这样也可以在一定程度上提高数据传输速率，以避免出现数据卡死的现象。同理，终端设备12和终端设备13也可以使用相同的方法进行数据传输，从而可以在一定程度上提升数据传输速率，提高用户体验。
示例性的，当终端设备11通过相同WiFi(以下记为WiFi 01，即无线访问接入点01对应的WiFi)局域网络中的任何终端设备(终端设备12和终端设备13)与无线访问接入点01间建立的第二传输链路的数据传输速度达不到一定速度阈值时(针对上述示例中的第二种情况)，或终端设备11的数据与WiFi 01无法传输时(例如断开连接)(即第一类传输链路中不存在目标传输链路)，终端设备11可以通过不在相同WiFi局域网络中的终端设备(如图3中的终端设备14和终端设备15)与不同无线访问接入点02(网络设备02)和无线访问接入点03(网络设备03)间建立的第二传输链路(即第二类传输链路)进行数据传输。即可以通过如图3所示的传输链路4(终端设备11通过终端设备14与无线访问接入点02间的第二传输链路)、传输链路5(终端设备11通过终端设备15与无线访问接入点03间的第二传输链路)进行数据传输。此种情况下，终端设备11、终端设备14和终端设备15均开启数据转发功能。
进一步的，若终端设备通过所有WiFi局域网络中的任何终端设备建立的第一传输链路和第二传输链路的数据传输速度均达不到一定速度阈值或都断开了连接时，则可以考虑终端设备通过蜂窝网络与基站(即网络设备)间的进行数据传输。终端设备11可以通过5G网络(终端设备11与基站间的第一传输链路，终端设备11通过其他终端设备与基站间的第二传输链路)进行数据传输。
本公开实施例支持第一终端设备与M个网络设备间的多路径并行数据传输，具体的第一终端设备可以通过与邻近终端设备建立的D2D通信链路，与网络设备间进行数据传输，提升了数据传输的速度，尤其可以改善终端设备在5G或WIFI信号较差的情况下，数据传输时出现卡顿现象的问题。
由于5G网络数据下载、上传耗电非常大，本公开实施例中，优先选择通过D2D模块与WiFi功能模块进行数据传输时，可以降低耗电，并且无需移动数据流量，因此可以提升用户体验。第一终端设备和/或第一终端设备的临近D2D终端设备通过WIFI无线局域网进行同步数据下载或上传，既可以改善第一终端设备所连接的WIFI在信号较差或信号差出现跳频、重新连接WiFi时出现卡顿现象，而且又可以省移动数据流量、省电。
传统技术中是终端设备与网络设备(尤其WiFi网络)的单向连接，本公开实施例中，是基于5G D2D技术的，终端设备与网络设备(尤其WiFi网络)的多链路连接，并且支持多传输链路并行数据传输，即要求网络设备(尤其WiFi网络)与各D2D终 端设备之间支持多传输链路的数据传输与共享。
本公开实施例提供了一种数据传输方法，在第一终端设备与M个网络设备间建立有N条传输链路的情况下，第一终端设备从该N条传输链路中，确定目标传输链路；并通过该目标传输链路传输目标数据；其中，该目标传输链路为该N条传输链路中的至少一条；任意一条传输链路为：第一传输链路或第二传输链路，第一传输链路为第一终端设备与一个网络设备间建立的传输链路，第二传输链路为第一终端设备通过一个第二终端设备与一个网络设备间建立的传输链路，N为大于1的整数，M为小于或等于N的正整数。通过该方案，在传输目标数据之前，终端设备先从其建立的N条传输链路中，确定至少一条传输链路，通过该至少一条传输链路共同传输该目标数据，可以提高数据的传输速率。而且通常情况下，终端设备会从N条传输链路中选择传输速率较好的传输链路，作为该至少一条传输链路。如此在数据传输过程中，终端设备不会切换通信方式，从而不会因正在传输的数据被中断而导致数据传输失败。
如图5所示，本公开实施例提供一种终端设备120，该终端设备120为第一终端设备，该终端设备120包括：确定模块121和传输模块122；确定模块121，用于在第一终端设备与M个网络设备间建立有N条传输链路的情况下，从N条传输链路中，确定目标传输链路；传输模块122，用于通过确定模块121确定的目标传输链路传输目标数据；其中，目标传输链路为N条传输链路中的至少一条；任意一条传输链路为：第一传输链路或第二传输链路，第一传输链路为第一终端设备与一个网络设备间建立的传输链路，第二传输链路为第一终端设备通过一个第二终端设备与一个网络设备间建立的传输链路，N为大于1的整数，M为小于或等于N的正整数。
可选地，N条传输链路包括一条第一传输链路和N-1条第二传输链路，或者，N条传输链路包括N条第二传输链路；其中，第一传输链路为第一终端设备与一个网络设备间的传输链路，每条第二传输链路为第一终端设备通过一个第二终端设备与一个网络设备间的传输链路。
可选地，在目标传输链路的链路数量大于1的情况下，传输模块122，具体用于按照目标传输链路的链路数量以及目标数据的数据量，通过确定模块121确定的目标传输链路传输目标数据。
可选地，确定模块121，具体用于按照预定规则，从N条传输链路中，确定目标传输链路；其中，预定规则包括以下至少一项：传输链路的信号质量大于或等于预定阈值，传输链路处于空闲态，传输链路对应的第一网络设备挂载终端设备的数量小于或等于第一网络设备挂载终端设备的负载能力。
可选地，N条传输链路包括一条第一传输链路和N-1条第二传输链路；确定模块121，具体用于按照预定规则，从N条传输链路中的第一类传输链路中，确定目标传输链路，第一类传输链路为：传输链路对应的网络设备与第一传输链路对应的网络设备相同的传输链路；在第一类传输链路中不存在目标传输链路的情况下，按照预定规则，从第二类传输链路中确定目标传输链路，第二类传输链路为N条传输链路中除第一类传输链路之外的传输链路。
可选地，目标传输链路对应的网络设备均为无线访问接入点。
可选地，一个第二终端设备的一个应用中包括第一标识，第一标识用于指示第一 终端设备的用户。
