13.9 Manual Response to a Network Request for PDP Context
ActiCGANS
Description:
The command requests the MT to respond to a network request for GPRS PDP context activation
which has been signaled to the TE by the RING or +CRING: unsolicited result code. The <response>
parameter allows the TE to accept or reject the request.
If <response> is 0, the request is rejected and the MT returns OK to the TE.
If <response> is 1, the MT follows the following procedure.
Commands following the +CGANS command in the AT command line, shall not be processed by the
MT.
If the <L2P> parameter value is unacceptable to the MT, the MT shall return an ERROR or +CME
ERROR response. Otherwise, the MT issues the intermediate result code CONNECT and enters
V.250 online data state.
The detailed behavior after the online data state has been entered is dependent on the PDP type. It is
described briefly in clauses 8 (for X.25) and 9 (for IP) and in more detail in GSM 09.61 and the
specifications for the relevant PDPs. PDP context activation procedures shall take place prior to or
during the PDP startup.
One or more <cid>s may be specified in order to provide the values needed for the context activation
request. During the PDP startup procedure the MT has the PDP type and the PDP address provided
by the network in the Request PDP Context Activation message. The MT may also have some or all
of the following information -
The MT may have a priori knowledge, for example, it may implement only one PDP type.
The command may have provided an <L2P> parameter value.
The TE may provide one or both of PDP type and PDP address to the MT in the PDP startup.
If any of this information is in conflict, the command will fail.
If one or more <cid> is given then an attempt shall be made to identify an appropriate context
definition by matching the PDP type and PDP address in the network request with the PDP type and
document. It may not be edited, copied or circulated without prior written agreement by iWOW Connections Pte Ltd.
