14.10.6 Notes
One 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.
If a is given, its information must match with the PDP type and PDP address in
the network request as follows:
• The PDP type must match exactly.
• The PDP addresses are considered to match if they are identical or if the
address in the context definition is unspecified.
If any of this information is in conflict, the command will fail.
The context is activated using the values for PDP type and PDP address provided by
the network, together with the other information found in the PDP context definition.
After data transfer is complete, and the layer 2 protocol termination procedure has
completed successfully, the V.25ter command state is re-entered and the MT returns
the final result code OK.
In the event of an erroneous termination or a failure to startup, the V.25ter command
state is re-entered and the MT returns the final result code NO CARRIER or, if
enabled, +CME ERROR. Attach, activate and other errors may be reported. It is also
an error to issue the +CGANS command when there is no outstanding network
request.
This command may be used in both normal and Wireless CPU ® compatibility modes.
