EPC: service request (not implemented)
The service request procedure is a not implemented feature.
Service request happends when a UE is still registered to the network, but its S1 connection is released due to inactivity, the UE has no radio resources available.
The service request can be triggered by the UE (uplink traffic), or by the network (downlink traffic).
More detailed explanation of the service request procedure can be found here:
