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.
