摘要：
A method of periodically attempting to access the HPLMN or an EHPLMN with higher priority in NTN systems with discontinuous coverage is proposed. A UE registered in VPLMN starts a timer T to periodically attempt to obtain service on its HPLMN or EHPLMN. When access stratum is deactivated due to discontinuous coverage in NTN, the UE does not stop the timer T, and postpone the periodic attempts to a later time, e.g., upon or after the UE activates the access stratum.
