Patent ID: 10764861

Abstract:
In one of its aspects the technology disclosed herein concerns a communications system comprising a radio access node (22) and a wireless terminal (26). The wireless terminal comprises receiver circuitry (40) and transmitter circuitry (44) as well as terminal processor circuitry (40). The receiver circuitry (40) is configured to receive, from the radio access node (22), a Radio Resource Control (RRC) message comprising information configuring a Radio Access Network-based (RAN-based) notification area. The terminal processor circuitry (40) is configured to initiate, in a case where the wireless terminal is in an inactive state, a RAN-based notification area update procedure upon the wireless terminal moving out of the configured RAN-based notification area. The information configuring the RAN-based notification area comprises one or more tracking area codes, each of the one or more tracking area codes being used to identify a tracking area.
