AI Technical Summary

Technical Problem

In user-intensive scenarios, when the terminal device is released to receive multicast services in a non-connected state, the new base station cannot determine how the multicast radio bearer is configured, resulting in network congestion and user service experience impact.

Method used

By sending instructions to the second network device, indicating whether the multicast broadcast wireless bearer needs to be reconfigured to the terminal device, the problem that the new base station cannot determine the multicast radio bearer configuration is solved.

Benefits of technology

It is realized that when the terminal device is accessed, it is clear whether it is necessary to reconfigure the multicast radio bearer, which reduces signaling overhead and improves the user's business experience.

Abstract

The invention discloses a communication method and device, and relates to the field of communication. The method comprises the following steps: a first network device sends an RRC release message to a terminal device joining a multicast session, wherein the RRC release message is used for indicating that the terminal device is released to a non-connection state; and the first network equipment sends indication information to the second network equipment, wherein the indication information is used for indicating whether the multicast broadcast radio bearer needs to be reconfigured for the terminal equipment. And the second network device reconfigures the multicast broadcast radio bearer for the terminal device according to the indication information, or does not reconfigure the multicast broadcast radio bearer for the terminal device. According to the invention, the indication information is sent to the second network equipment, so that a decision basis for whether to reconfigure the multicast broadcast wireless bearer for the terminal equipment is provided for the second network equipment.
