Command Description

The test command is used for requesting information on the supported GPRS service states. The read command returns the current GPRS service state.

The write command is used to attach the MT to, or detach the MT from the GPRS service. After the command has completed, the MT remains in V.250 command state. If the MT is already in the requested state, the com- mand is ignored and the OK response is returned. Any active PDP contexts will be automatically deactivated when the attachment state changes to detached.

Parameter Description

<state>(num)

Indicates the state of GPRS attachement.

0(P)	detached
[1]	attached

Notes

•If the MT is in dedicated mode, write command returns "+CME ERROR: operation temporary not allowed".

•When the module is GPRS attached and a PLMN reselection occurs to a non-GPRS network or to a network where the SIM is not subscribed to for using GPRS, the resulting GMM (GPRS mobility management) state according to GSM 24.008 is REGISTERED/NO CELL, meaning that the read command will still show

<state>=1.
