Patent ID: 11405889

Abstract:
Apparatuses, methods, and systems are disclosed for responding to RAN paging failures. One apparatus (300) includes a processor (302), a transmitter (310), and a receiver (312). The receiver (312) receives (702) an access network context release request including an indication of RAN paging failure. The processor (302) suspends (704) a protocol data unit session deactivation procedure and triggering core network paging in response to receiving the indication of RAN paging failure. In response to the core network paging failing, the processor (302) resumes (706) the protocol data unit session deactivation procedure. In response to the core network paging succeeding, the transmitter (310) transmits (708) an access network context establishment request to a target RAN. In response to receiving an access network context establishment response from the target RAN, the transmitter (310) transmits (710) a protocol data unit session modification request. In response to receiving a protocol data unit session modification response, the transmitter (310) transmits (712) a data forwarding request to a source RAN.
