Embodiments of the present invention provide a service discovery method and electronic equipment, which relate to the technical field of communications. The method for service discovery includes: a first device sends a service discovery request to at least one second device connected to the access point via an access point; the service discovery request is used to query the at least one second device The first device requests the queried service; the first device receives a service discovery response sent by the at least one second device, and the service discovery response is a response of the at least one second device to the service discovery request ; The service discovery response includes the services supported by the at least one second device. In the embodiment of the present invention, in the scenario where multiple electronic devices are connected to the access point, the interaction of service discovery messages between multiple electronic devices can be realized without the electronic device disconnecting from the access point, improving The efficiency of service discovery is improved, and then the efficiency of intercommunication is improved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a service discovery method and electronic equipment. Background technique [0002] The wireless local area network standard 802.11 formulated by IEEE defines two network structure modes, one is based on infrastructure, that is, one node is used as an access point (Access Point, AP), and other nodes are used as stations (Station, STA). The access point provides access services, and other nodes connect to the access point and access the network through the access point. The second is the independent basic service set (Independent Basic Service Set, IBSS) mode, under this network structure, each device is an equal site, and establishes connections between each other. In specific implementation, in some scenarios, for example, two mobile phones need to be connected to each other, and the 802.11 standard cannot conveniently realize the discovery and connection between ...
