需要说明的是，WIFI(WIreless-FIdelity，无线保真)是一种可以将个人电脑、手持设备等终端以无线方式互相连接的技术。
S106，判断目标中继节点的信号强度差值是否超过门限。
在一个实施例中，根据远端信号强度设置门限，可根据用户需要或历史数据对远端信号强度对应的门限进行设置，保证远端终端选取目标中继节点后，系统用电最佳。
S108，若是，则通过目标中继节点进行中继传输。

图4示出本公开实施例中再一种中继节点接入方法流程图，如图4所示，本公开实施例中提供的中继节点接入方法包括如下步骤：
S402，计算远端终端U_0与多个中继节点为R_i之间的信号强度差值S_i0。
在一个实施例中，在P-RAN架构下，中继节点可以通过蜂窝或WiFi频率来作为中继。
为了便于说明，设远端终端为U_0，其与信源终端C通信时的下行信号强度为S_0；
备选中继节点为R_i，其与信源终端C通信时的下行信号强度分别为S_i；
远端终端U_0与备选中继节点为R_i之间的信号强度，即远端终端U_0与备选中继节点为R_i的信号强度差值为S_i0；
需要说明的是，信号强度差值S_i0是基于上下行信道互译假设得到的信号强度。
S404，基于远端终端U_0与多个中继节点为R_i之间的信号强度差值S_i0，生成一组针对远端终端U_0的备选中继集合R＝{R_1，R_2，R_n}。
其中，集合中的备选中继数目为n，且对于每一个R_i，i＝1...n，满足S_i0≥S_0。
在一个实施例中，这一过程可以通过中继服务发现过程完成。
S406，判断远端终端U_0是否进行中继传输以及从备选中继集合R中选择一个中继节点。
在一个实施例中，图5示出本公开实施例中一种中继节点选择示意流程图，如图5所示，判断远端终端U_0是否进行中继传输以及从备选中继集合集合R中选择一个中继节点的方法为：
计算S_i0＝S_i-S_0，i∈(1...n)；
令S_m0＝max(S_10，...，S_n0)；
如果S_m0超过一个给定的门限r，则判断需要进行中继传输，且选择中继节点R_m作为中继节点；否则，不进行中继传输。
上述实施例中，针对远端终端为U_0与信源终端C通信时的下行信号强度为S_m0选择特定的门限γ，可以做到在利用中继传输使远端终端U_0速率翻倍的性能提升前提下，所消耗的总的能量小于不适用中继的情况下实现相同效果时远端终端U_0所消耗的能量，保证参与PRAN的终端总电量是有收益而不是有损失的，能够达到系统的终端用电最佳，为移动运营商的室内覆盖提供了一种便捷、可控可管的技术方案，降低建网成本，为用户提供了一种简单、安全的享受高速上网和流量共享的方式。
