Application: Mbs data processing method and device (Patent ID: US20230380002A1)
The patent filed by KT Corp. describes a method and device for processing multicast and broadcast services (MBS) data. The method involves switching the radio resource control (RRC) state to an RRC inactive state, receiving a message for MBS session state notification from a base station, and initiating an RRC connection resume procedure for an RRC state change based on the message. The claims outline specific steps involved in the method, such as receiving a paging message with MBS session identification information, triggering the RRC connection resume procedure when joining an MBS session, and controlling the suspension of an MBS radio bearer for the session.
The patent also includes a method for controlling MBS data processing by a base station, which includes transmitting an RRC connection release message to the UE, sending a paging message with MBS session identification information, and receiving an RRC connection request message from the UE when initiating an RRC connection resume procedure. Additionally, the patent describes a user equipment (UE) for processing MBS data, with a controller for switching the RRC state and a receiver for receiving paging messages. The UE is designed to trigger the RRC connection resume procedure when joining an MBS session and to suspend the MBS radio bearer for the session when switching to the RRC inactive state.
