Abstract:
1. A method for recovering from a radio resource control (RRC) operational state mismatch between a user equipment (UE) device and one or more network elements of a network (NW) operating in accordance with a Long Term Evolution (LTE) protocol, the method comprising the UE device: determining a first RRC operational state of the UE device, wherein the first RRC operational state of the UE device includes an RRC idle state or an RRC connected state; determining the RRC operational state mismatch when the first RRC operational state of the UE device does not match a first RRC operational state for the UE device maintained at the one or more network elements of the NW, wherein the first RRC operational state for the UE device maintained at the one or more network elements of the NW includes an RRC idle state or an RRC connected state; sending at least one RRC message from the UE device to the NW to release NW resources assigned to the UE device, in response to determining the RRC operational state mismatch; and transitioning the UE device from the first RRC operational state of the UE device directly to a second RRC operational state of the UE device after sending the at least one RRC message to the NW, wherein the second RRC operational state of the UE device includes an RRC idle state or an RRC connected state, and wherein the second RRC operational state of the UE device matches the first RRC operational state for the UE device maintained at the one or more network elements of the NW.
