GPRS <PDP_type>, <PDP_addr> [, [<L2P>][,<APN>]] GPRS network request for
PDP context activation
The optional <priority> indicates the eMLPP priority level of the incoming call by
paging, notification or setup message. The priority level values are as defined in
eMLPP specification 3GPP TS 22.067.
<subaddr>: string type sub address of format specified by <satype>
<satype>: type of sub address octet in integer format (refer 3GPP TS 24.008 sub
clause 10.5.4.8)
<PDP_type>,<PDP_addr> and <APN> are as defined in the Define PDP Context
(+CGDCONT) command. The optional <L2P> proposes a layer 2 protocol to use
between the MT and the TE. It is defined in the Enter GPRS Data Mode (+CGDATA)
command. If the MT is unable to announce to the TE the network's request (for
example it is in V.25ter online data state) the MT shall reject the request. No
corresponding unsolicited result code shall be issued when the MT returns to a
command state.
The
“AT+CRC” will be set <mode> to 0.
