9.1.17 SIEMENS release cause for Session Management (SM) (AT+CEER)
Number Description
3 The MS has not got any answer to the ACTIVATE PDP CONTEXT request message
sent five times to the network
4 A MT PDP context which is active or in the activation process is deactivated because
another MT PDP context with the same TI is requested by the network to be activated
5 A MT PDP context which is active or in the activation process is deactivated because
another MT PDP context with the same TI is requested by the network to be activated.
The activation request is rejected by the SM sending the cause 'insufficient resources'
to the network because the SM was not able to perform the necessary comparisons
for a static PDP address collision detection.
6 A MT PDP context which is active or in the activation process is deactivated because
another MT PDP context with the same TI is requested by the network to be activated.
As a static PDP address collision with an MO activating PDP context has been de-
tected by the SM the SM discards the activation request
7 A MT PDP context request has been indicated but could not be processed in time.
The activation request is rejected by the SM sending the cause 'insufficient resources'
to the network.
