Title:

METHOD FOR ALLOWING A USER EQUIPMENT (UE) TO RESPOND CELLULAR NETWORK SIGNALLING OVER A NON-CELLULAR RADIO ACCESS NETWORK

Document Type and Number:

WIPO Patent Application WO/2021/062718

Kind Code:

A1

Abstract:

A method for allowing a user equipment (UE) to respond cellular network signalling over a non-cellular radio access network. The UE initiates a service request procedure for a cellular network service and receives a service reject message in response. The UE enters an inactive state over a non-cellular radio access. Upon receiving an indication through cellular network signalling indicating that a set of downlink data are available for transmission to the UE, the UE responds to the indication over the non-cellular radio access by initiating another service request procedure that activates the non-cellular radio access, enters an active state of the UE over the non-cellular radio access, and receives the set of downlink data through user plane or connection of the non-cellular radio access.
