    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.

    Abstract: In a GSM mobile wireless telecommunications system, a method for conveying signaling between a mobile station (40) and a base station (30) and (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 f or 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.
