    Abstract: IN A GSM MOBILE WIRELESS TELECOMMUNICATIONS SYSTEM, A METHOD FOR CONVEYING SIGNALING BETWEEN A MOBILE STATION (40) AND A BASE STATION (30,32) VIA A CDMA AIR INTERFACE INCLUDES GENERATING A SIGNALING MESSAGE BASED ON A GSM INTERFACE STANDARD. DATA LINK SERVICES ARE PROVIDED TO PROCESS THE MESSAGE FOR TRANSMISSION OVER THE CDMA AIR INTERFACE, AND THE PROCESSED MESSAGE IS THEN TRANSMITTED OVER THE CDMA AIR INTERFACE. PREFERABLY, THE DATA LINK SERVICES ARE PROVIDED BY A DATA LINK LAYER (54), WHICH PRODUCES AN IS-95 MESSAGE FOR TRANSMISSION.(FIG.3A)

    Abstract: In a wireless communication system, a method and apparatus of communicating between at least one base station and a core network is claimed. Signaling messages and voice streams are transported using packet-switched protocols (IP). A CIC field (Circuit Identity Code) is used to identify at least one VoIP streams. The CIC field may be interpreted as a UDP port number for the voice over IP stream. Also, a synchronization source or contributing source filed of a RTP header may be used as the CIC field (fig. 1).

    Abstract: A method for preventing interference between electromagnetic (EM) signals, consisting of toggling a first transceiver, adapted to transmit in a first EM frequency band, and a second transceiver, adapted to transmit in a second EM frequency band, different from the first EM frequency band, between an on-period when the first transceiver is able to transmit and the second transceiver is prevented from transmitting, and an off-period when the first transceiver is prevented from transmitting and the second transceiver is able to transmit. The method further includes inhibiting a third transceiver, adapted to transmit in the first EM band, from transmitting during the off-period, and inhibiting a fourth transceiver, adapted to transmit in the second EM band, from transmitting during the on-period.
