Abstract: This application provides a service transmission method and a communication apparatus. The method includes: A first access point sends a radio frame to a second access point, where the radio frame indicates a service synchronously transmitted by the first access point and the second access point; and the first access point initiates the service. According to the foregoing technical solution, in this application, service synchronization between the first access point and the second access point can be implemented. Correspondingly, the first access point and the second access point may orderly initiate the service, so that network congestion and stalling can be alleviated.

Abstract: Embodiments of the present invention disclose Wireless Mesh Network (WMN) for notifying proxy update. By constructing the proxy update add message, where the proxy update add message includes the address of terminal, the current proxy node address after terminal switching and the destination node address of the terminal, and taking the address of the original proxy node before terminal switching as the address of the destination node, and sending the proxy update add message constructed to the original proxy node, where the proxy update add message is used for updating proxy information of the terminal in the proxy information table of the original proxy node to be the current proxy node address. It makes sure that packets received by the original proxy node which should be sent to the terminal could be received by the terminal, and packet loss rate during terminal switching could be reduced.
