NOTE
The unsolicited result codes and the corresponding events are defined as follows:
1. +CGEV: REJECT <PDP_type>, <PDP_addr>: A network request for PDP context activation
occurred when the MT was unable to report it to the TE with a +CRING unsolicited result code and
was automatically rejected.
Note: This event is not applicable for EPS.
2. +CGEV: NW REACT <PDP_type>, <PDP_addr>, [<cid>]: The network has requested a context
reactivation. The <cid> used to reactivate the context is provided if known to the MT.
Note: This event is not applicable for EPS.
3. +CGEV: NW DEACT <PDP_type>, <PDP_addr>, [<cid>]: The network has forced a context
deactivation. The <cid> used to activate the context is provided if known to the MT.
4. +CGEV: ME DEACT <PDP_type>, <PDP_addr>, [<cid>]: The mobile equipment has forced a
context deactivation. The <cid> used to activate the context is provided if known to the MT.
5. +CGEV: NW DETACH: The network has forced a Packet Domain detach. This implies that all active
contexts have been deactivated. These are not reported separately.
