Method, apparatus, and system for carrying out multimedia service in wireless local area network

摘要

Embodiments of the present invention provide a method, an apparatus, and a system for carrying out a multimedia service in a WLAN. The method includes: receiving a multicast data stream sent by a data server; and monitoring in real time a receiving rate of a terminal connected to an access point, if the receiving rate is higher than or equal to a multicast sending rate at which the access point sends multicast data, sending, in a multicast mode, the multicast data stream sent by the data server to the terminal, and if the receiving rate is lower than the multicast sending rate, converting the multicast data stream sent by the data server into a unicast data stream and sending the unicast data stream to the terminal. In the solution, the mode of sending multimedia data stream by the access point is determined according to the receiving rate of the terminal, which improves the transmission quality of the multimedia data stream and enhances the user experience.
