FIELD: radio engineering, communication.
SUBSTANCE: wireless communication method performed by the communication device comprises: receiving the first starting point indication for the first detection interval from the plurality of detection intervals, the first duration for the first detection interval, the second starting point for the first personal call interval of the plurality of personal call intervals, and the second duration for the first personal call interval; transmitting the detection packet during the first detection interval from the plurality of detection intervals. The detection packet advertises a service provided in the wireless communication network, and the plurality of detection intervals comprises repeating time intervals, when the plurality of communication devices are configured to transmit and receive detection packets. A plurality of communication devices is aware about the first starting point and the first duration; and receiving a personal call packet from the first communication device during the first personal call interval from the plurality of personal call intervals. The personal call packet shows the interest in the service, the plurality of personal call intervals contains repeating time intervals, when a plurality of communication devices are configured to transmit and receive personal call packets. A plurality of communication devices is aware of the second starting point and the second duration, the plurality of personal call intervals does not overlap with the plurality of detection intervals.
EFFECT: reducing electricity consumption, when the communication device is entered into the communication environment.
