Apparatus for signaling circle of friends

摘要

A device and method is provided for signaling an affinity of a peer device. According to one embodiment, the device receives a wireless signal from the peer device and determines the presence of the peer device based on the received signal. The device is able to detect the peer device when the peer device is within the vicinity or a certain proximity of the device. The received signal carries an affinity code of the peer device so that the device can detect the affinity of the peer device by comparing the received affinity code with its preset affinity code. If the two affinity code match, the device notifies the user of the presence of another user and signals that the two users share the same affinity.
