Abstract
A device, system, and method synchronizes network states for a user equipment (UE) during a handover from a first network to a second network while the UE was in a radio resource control (RRC) idle state. The method includes determining whether a first context associated with a first non-default bearer over the first network is stored on the UE. The method includes when the first context is determined, determining a second context associated with a second non-default bearer over the second network is stored on the UE. The method includes transmitting a request to the first network over a default bearer for network state information relative to the first network. The method includes receiving the network state information from the first network, the network state information indicating that the UE does not have the first non-default bearer over the first network established. The method includes deleting the first context.
