Abstract The present invention relates to a system for transmitting calling identifier on pilot channels in wireless communication systems. In one embodiment, the wireless communication system is a wireless communication systems based on CDMA and having pilot channels. The calling method of the present invention transmits calling identifier on pilot channels in a fashion of uncoded modulation spread spectrum signal of OOK(open-close keying)or ASK(amplitude shift keying). A mobile station monitors the present of the calling identifier at the given position of the pilot channels, which is determined by using a hash function of the International Mobile Equipment Identity(IMEI). The calling identifier notifies the mobile station to receive the next forward chain circuit common control or the calling channels.
