参照图1，示出了本申请的一种终端的通信方法实施例的步骤流程图，具体可以包括如下步骤：
步骤101，终端从预置的公共入网信道，获取所述终端所在区域的网络唯一标识信息；
LoRaWAN协议规定了不同区域的频谱标准，例如，中国470MHz ISM(Industrial Scientific Medical，工业科学医疗)频段频谱标准、中国920MHz ISM频段频谱标准、日本920MHz ISM频段频谱标准、新加坡920MHz ISM频段频谱标准等。频谱标准规定了不同区域终端的ISM频段、信道频率、数据速率、发射功率、可用信道字段CFList(channel frequency list)等物理层参数。
在本申请实施例中，LoRa设备预置有至少一个公共入网信道。公共入网信道可以为多个区域频谱标准的共有频点。

在本申请实施例中，所述步骤101可以包括如下子步骤：
子步骤S11，所述终端在预置的公共入网信道向服务器发送入网请求帧，并在所述公共入网信道接收服务器发送的入网应答帧；
终端可以在公共入网信道向服务器发送入网请求帧(Join-request)，服务器在接收到入网请求帧后，可以向终端发送入网应答帧(Join-accept)。
