Abstract

The invention discloses a service discovery method and a terminal. The method of the invention includes: the terminal sends a service query request message to the router by using a first discovery protocol, and starts monitoring the broadcast message of the router; if the terminal does not receive the broadcast of the service query request message by the router within a first preset time period message, it is determined that the router does not support the first discovery protocol, and the second discovery protocol is used to send the service query request message again; if the broadcast message is received within the first preset duration, it is determined that the router supports the first discovery protocol, the terminal continues to wait for a second preset duration; if it receives a response message from the multicast group member to the broadcast message within the second preset duration, it establishes a connection with the multicast group member, and if the 2. If the response message is not received within a preset time period, it is determined that there is no member to provide the service in the multicast group. The invention can realize faster detection and switching, and improve the efficiency of service discovery.

Description

technical field [0001] The present invention relates to the communication field, in particular to a service discovery method and a terminal. Background technique [0002] With the development of smart devices, multi-screen interaction has been more and more widely used. [0003] Multi-screen interaction refers to, based on DLNA (Digital Living Network Alliance, Digital Living Network Alliance), AirPlay (wireless communication technology developed by Apple Inc.) and other protocols or proprietary protocols, through wireless local area network connection, on different multimedia terminals. Multimedia (such as audio, video, pictures, etc.) content transmission, display and other operations. [0004] Among them, the discovery protocol that provides the service discovery function is a very important part. Its main function is to discover the address of the smart device that provides multi-screen interactive services in the local network, so as to establish a connection with the ...
