  • Patent number: 11356920
    Abstract: A communications method and device, to reduce service interruption time and signaling overheads that are generated when an access point that provides a communication service for a station changes because the station moves or changes a direction. First frames sent by different access points in an access point set to a station include a same sending address. In this way, when the station moves or changes a direction, the access point that provides the communication service for the station changes from one access point in the access point set to another access point. Because first frames sent by access points in the access point set include a same sending address, the station may consider the access point set as one access point.
