Abstract

The present invention relates to a multi-media conversation service quality management method in a variety of wireless network convergence environments, including: user II is conducting a one-way multimedia conversation with user I, and when user I's terminal decides to switch, perform the following steps: A1) user I Judging the target network type to be switched into; A2) user I sends a switching notification signaling to user II, which records the target network type in the switching notification signaling; A3) user II receives the user I sending in step A2) The switching notification signaling of the signaling, and then adjust the local audio / video encoding rate according to the target network type in the signaling; A4) after step A3) ends, the user II sends back a switching confirmation signaling to the user I; A5) the user I is in After step A2), wait for the handover confirmation signal from user II, and perform handover immediately when receiving the handover confirmation signal. The method of the invention can effectively improve the service quality of multimedia communication.
