AT命令表达式为：

+CGREG: <n>,<stat>[,[<lac>],[<ci>],[<AcT>],[

<rac>][,<cause_type>,<reject_cause>]]

其中<n>值有以下说明：

0          disable network registration unsolicited result code

1          enable network registration unsolicited result code +CGREG: <stat>

2          enable network registration and location information unsolicited result code

+CGREG: <stat>[,<[lac>,]<[ci>],[<AcT>],[<rac>]]

3          enable network registration, location information and GMM cause value information unsolicited result code

+CGREG: <stat>[,[<lac>],[<ci>],[<AcT>],[<rac>][,<cause_type>,<reject_cause>]]

求说明1,2的具体区别是什么？在线等. thx.

到底有没有人来帮忙回复一下呢？亲人们.
