AI Technical Summary

Technical Problem

After the terminal changes from a connected state to a disconnected state, it cannot receive the transmission status change information of the multicast service in a timely manner, resulting in the interruption of multicast service reception.

Method used

By using information transmission methods on the network side and the terminal side, the transmission state change of the multicast broadcast service (MBS) is determined and the non-connected terminal is notified, including changing the transmission mode from point-to-multipoint (PTM) to point-to-point (PTP) or requiring the terminal to enter the connected state to receive the multicast service.

Benefits of technology

This ensures that when a terminal enters a disconnected state, the transmission status change information of the multicast service can be notified in a timely manner, avoiding the interruption of multicast service reception due to changes in network policies and ensuring the continuity of data reception.

Abstract

This application discloses an information transmission method and apparatus, which can notify the terminal of the transmission status change information of the Multicast Broadcast Service (MBS) after the terminal enters a connectionless state to receive multicast services, thereby avoiding the problem of multicast service reception interruption caused by the terminal's inability to receive relevant indication information due to changes in network policies. On the network side, the information transmission method provided in this application includes: determining that the transmission status of the multicast broadcast service (MBS) has changed; and notifying the connectionless terminal of the MBS transmission status change information.
