* CLR while idle is broken after 7031856cd7
Cancel Location Request arriving while UE is idle will not proceed to paging due to this check for S1 connection. Using new flag "isAnswer" to bypass this check to allow paging to occur when we are not doing a AIA/ULA related procedure.
* No Context Setup is required when sending the detach request. If the paging was due to wanting to send a Detach Request to the UE, then we fast track to sending the detach request.
* emm-sm.c:
In the case of MME initiated detach while UE is idle, there is no initial conext setup. We go right from the service request after paging into sending the detach request. TS23.401
mme-path.c:
Using nas_eps.type in the case of MME Initiated Detach while UE is idle does not work. nas_eps.type would represent the service request.
mme-s11-handler.c:
After S11 action, no action should be taken. We want to wait for the detach accept from the UE before proceeding with the S1 release (detach).
* InitialContextSetup should occur for detach.
