Apparatus and method for transmitting and receiving multicast broadcast service

摘要

A multicast broadcast service (MBS) receiving device establishes an MBS connection with an MBS transmitting device through a connection establishment message. When it is determined to receive MBS right after establishing the MBS connection, the MBS receiving device starts to receive the MBS right after establishing the MBS connection. When it is determined to not receive MBS right after establishing the MBS connection, the MBS receiving device transmits an MBS report message to the MBS transmitting device and then starts to receive the MBS.

1. A method for a multicast broadcast service (MBS) transmitting device to transmit MBS to an MBS receiving device, the method comprising:
establishing an MBS connection with the MBS receiving device through a connection establishment message; determining, using the connection establishment message, whether the MBS receiving device is set to immediately receive an MBS upon establishing the MBS connection; and determining an MBS reception start time based on whether the MBS receiving device is set to immediately receive an MBS upon establishing the MBS connection; wherein the MBS reception start time is a time following the establishment of the MBS connection if the MBS receiving device is set to immediately receive an MBS upon establishing the MBS connection; and wherein the MBS reception start time is a time following a receipt of an MBS report message if the MBS receiving device is not set to immediately receive an MBS upon establishing the MBS connection.
