xxx - Pwr表示 发射功率等级; Pwr means TX power level
0 - 时隙; TS (Time Slot)
1 - 时间前置量; 显示手机和基站距离, 乘以500以公尺计算; TA - Timing Advance
x - RLT - Radio Link Timeout
xxxx - 不详;
51(C1)- 多径衰耗标准, 本人英语和基站知识不灵光, 大家自己体会吧C1 (path loss criterion, used for cell selection and reselection, the range in GSM is -99..99)
CCCH - 载频类型之一; (xxCH) type of current channel:
AGCH -(Access Grant Channel)许可连接频道由网络到手机单向频道, 安排专用控制信道以完成连接上网;
* SDCC -(SDCCH:Stand-alone Dedicated Control Channel)独立专用控制信道;
* TFR -(TCH:Traffic Channels)业务信道;
* BCCH -(Broadcast Control Channel)广播控制信道;
*SEARCH-手机正在搜索网络信号;
* NSPS -(No Service & Power Save),无网络服务, 手机正处于省电模式;  
通话中CHT项改变:AGCH->
