步骤 203 , MTC终端向无线网络发送 MTC数据 ^艮告消息， 该 MTC数据 报告消息包括： MTC终端的唯一标识、 鉴权信息以及业务数据；
MTC终端唯一标识是一个数字， 如 32bit或者 64bit的二进制数。 所述 数字占用位宽可以变化， 用于在无线网络中唯一标识 MTC终端。
鉴权信息是 MTC 终端根据当前时间戳（一般精确到分钟） 以及预设的 初始码， 通过一种随机数方法产生。 相应在基站控制器 （BSC ) 处也有一套 鉴权系统， 可以验证 MTC终端上报的鉴权信息。
业务数据可以包含 MTC 终端实时获取的特定数据 （可以是生命指征， 取决于 MTC终端的类型） ， MTC终端也可以通过外部接口获得数据； 业务 数据也可以包含 MTC 终端监测的无线环境数据， 根据这种无线环境测量数 据， 基站控制器 （BSC ) 能进一步精确定位 MTC终端的位置。
所述 MTC数据报告消息， 可以在现有 GSM/EDGE的消息结构上增加， 例如需要改变其中一个信元的取值范围。 MTC终端上报的 MTC数据报告消 息中预留业务数据的字段。
更优的， 本方法进一步包括以下步骤。 步骤 204: 基站控制器 （BSC ) 在接收到 MTC数据报告消息后， 发送 MTC设备控制消息。
所述 MTC设备控制消息， 可以在现有 GSM/EDGE的消息结构上增加， 例如需要改变其中一个信元的取值范围。 MTC终端接收到所述 MTC设备控 制消息， 也可以反馈确认消息。
无线网络发给 MTC终端的 MTC设备控制消息包含控制指令，用于控制 终端的行为。 MTC终端接收 MTC设备控制消息， 根据消息中的控制命令进 行相应操作， 如改变上报周期， 在服务终止后停止工作等。
更优的， 本方法进一步包括以下步骤。 步骤 205: 基站控制器 （BSC ) 将 MTC 终端唯一标识、 位置信息、 数据报告的时间戳、 业务数据等通过应 用接口 （API: Application Interface ) , 发送给应用服务器。

步骤 301 : MTC终端周期或者事件触发方式被唤醒， 扫描并同步上某个 小区， 接收小区的广播信道获取小区的系统信息.
步骤 302: MTC终端使用随机接入信道（RACH )发送信道请求消息给 无线网络， 并持续监听下行 AGCH信道,以接收基站控制器发送的立即指配 消息 ( Immediate Assignment ) 。
步骤 303 : 无线网络的基站 （BTS )检测随机接收信道， 获取包含的信 道请求消息， 传送到基站控制器 （BSC ) ， 基站控制器 （BSC ) 分配信道资 源， 并通过立即指配消息通知 MTC终端。
步骤 304: MTC终端根据立即指配消息中指示的上行分组传输资源， 釆 用 MTC数据报告消息发送唯一标识以及可能的业务数据。
更优地， 所述立即指配消息可以包括终端的 ID、 鉴权信息。 终端 ID是 一个数字， 如 32bit或者 64bit的二进制数。 所述数字占用位宽可以变化， 用 于表示 M2M系统的终端编号。
鉴权信息和业务数据类似与第一实施例中的鉴权信息和业务数据。 更优地， 本实施例进一步包括步骤 305、 步骤 306。
步骤 305:无线网络 BSC通过某个实体处理来自 MTC终端的 MTC数据 报告消息， 并向 MTC终端发送 MTC设备控制消息。

更优地， 本实施例进一步包括步骤 307。
步骤 307: 无线网络的实体产生 MTC终端的实时 4艮告， 并转发给相关应 用。 实时报告包括 MTC终端的标识， MTC终端的地理位置， 接收到 MTC 终端的 MTC数据报告消息的时间戳，以及 MTC数据报告消息中的业务数据。
为了防止 MTC终端错过步骤 305 中的设备控制消息而陷入等待消息状 态， 在步骤 304中， 启动一个定时器， 当定时器超时， MTC终端进入空闲模 式不再继续等待。
为了识别来自低功耗 MTC终端的合法呼叫， 以上鉴权信息的产生和使 用方法如下：
MTC终端在业务数据中增加一个动态随机数， 并发送给无线网络。 这个 动态随机数根据当前的时间 （一般精确到分钟） 和预设的初始码 （和 MTC 终端绑定的一个固定数字） 来自动产生。
无线网络接收到特定 MTC终端的实时数据时， 根据当前的时间 （一般 精确到分钟） 和唯一的 MTC 终端配置来产生另一个动态随机数。 然后， 无 线网络比较从特定 MTC 终端收到的随机数， 如果相同， 则当前呼叫获得的
MTC数据报告消息通过认证。 如图 4所示， 本发明的第三实施例低功耗 MTC终端和无线网络的通信 方法。 本实施例中和第三实施例的区别是： 步骤 304、 步骤 305、 步骤 306 被替换为图 4所示的步骤 404、 步骤 405、 步骤 406。
