  • METHOD AND SYSTEM FOR HANDLING OF CLOSED ACCESS GROUP RELATED PROCEDURE
    Publication number: 20200396673
    Abstract: Accordingly, Example embodiments herein disclose a method for supporting a user equipment (UE) accessing one or more closed access group (CAG) cells via a radio access network. A core network apparatus may receive via the interface circuitry a request signal that includes a protected CAG identifier (ID) associated with the UE. The core network apparatus may de-conceal the protected CAG ID to determine a CAG ID. The proposed method can be used to define how the wireless communication system will perform the subscription check for the received CAG identifier. Further, the method can also be defined how to perform resume procedure on a CAG cell when the UE (100) is in a 5GMM-CONNECTED with inactive indication or 5GMM-IDLE with suspend indication.
