9.5 AT+CGDCONT - Command for Defining the PDP
Context
The AT+CGDCONT command defines the PDP context. The MT locally saves a
group of PDP contexts with <cid> as the index. Each record of the saved setting
environment contains a group of PDP related parameters. The write command saves
the group of PDP related parameters in the PDP contexts that use <cid> as the index.
Each PDP context is initially undefined. After the write command saves a group of
parameters in a PDP context, the PDP context is defined. The number of defined
PDP contexts that can be saved at the same time is determined by the value range of
<cid>.
If AT+CGDCONT= <cid> is sent, all parameters in the PDP contexts indicated by
<cid> are cleared. In this case, the PDP contexts become undefined again.
