4.12.1 GPRS Commands
This section defines commands that a terminal may use to control a GPRS MT. GPRS MTs vary widely in functionality. A class
A MT might support multiple PDP-types as well as circuit-switched data, and use multiple external networks QoS profiles. At
the other extreme, a class C MT might support only a single PDP-type using a single external network, and rely on the HLR to
contain the PDP context definition. A comprehensive set of GPRS-specific commands is defined below to provide the flexibility
needed by the more complex MT. The commands are designed to be expandable to accommodate new PDP types and interface
protocols, merely by defining new values for many of the parameters. Multiple contexts may be activated if the interface link-
layer protocol is able to support them. The commands use the extended information and error message capabilities described in
this specification. For MTs of intermediate complexity, most commands have simplified forms where certain parameters may
be omitted. For the simplest MTs, and for backwards compatibility with existing communications software, it is possible to
control access to the GPRS using existing modem-compatible commands. This "modem compatible" mode of operation is
described below.
4.12.1.1 +CGCLASS, GPRS Mobile Station Class
This command is used to set the g20 to operate according to the specified GPRS mobile class. If the requested class is not
supported, an ERROR or +CME ERROR response is returned. Extended error responses are enabled by the +CMEE command.
Read Command
The Read command returns the current GPRS mobile class.
