Method for handling a mobility management state transition after fallback to RRC establishment

A user equipment comprising:

• a wireless transceiver;
• and
• a processor and memory system coupled to the wireless transceiver, the memory system comprising processor-executable instructions that, responsive to execution by the processor, direct the user equipment to perform operations for handling a mobility management state transition after fallback to a radio-resource-control establishment, the operations comprising:
• transmitting a radio-resource-control request to a network to initiate a radio-resource-control connection procedure while operating in a mobility-management connected state;
• receiving, in response to the transmitting the radio-resource-control request, a radio-resource-control setup message from the network;
• based on the receiving of the radio-resource-control setup message from the network, communicating, from a radio-resource-control protocol layer at the user equipment to a mobility-management protocol layer at the user equipment, an indication of the fallback;
• and
• transmitting, in response to the receiving the radio-resource-control setup message, a radio-resource-control setup-complete message to the network, the radio-resource-control setup-complete message including a mobility-management message generated by the mobility-management protocol layer, the mobility-management message comprising:
• a service request;
• or
• a registration request.
