Title:
METHOD AND APPARATUS FOR WIRELESS COMMUNICATION USING SATELLITE ACCESS
Document Type and Number:
WIPO Patent Application WO/2024/035083
Kind Code:
A1
Abstract:
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a UE in a wireless communication system using satellite access is provided. The method includes identifying whether a NAS procedure is completable before a start of a DC; and in case that the NAS procedure is completable before the start of the DC, initiating the NAS procedure by transmitting a request message to a network entity. And a method for a UE in a communications network using a satellite to access the network comprises verifying if a communication process between the UE and the network via the satellite can be completed before a start of an unavailability period of the satellite or cannot be completed before a start of an unavailability period of the satellite. The UE may only initiate the communication process when it verifies that there is enough time for the communication process to be completed the start of the unavailability period of the satellite. The communication process between the UE and the satellite may comprise a NAS procedure. The UE may only trigger the NAS procedure when it verifies that there is enough time for the procedure to be completed before the start of the unavailability period of the satellite and loss of satellite coverage for the UE. The UE may trigger the NAS procedure during a time range for which the procedure can be completed before the start of the unavailability period of the satellite and loss of satellite coverage for the UE. The NAS procedure may be any of a registration procedure, a mobility registration update procedure, a NAS request procedure, an attach procedure, a tracking area update procedure, a service request procedure, a NAS mobility management procedure, a NAS session management procedure, NAS signaling, a NAS message, any similar message that is used in EPS (or in S1 mode).
