Abstract: Handoff between a wireless LAN and a cellular communication system is provided. A system is designed to provide nomadic cellular services including voice over I.E.E.E. 802.11. An 802.11 network is used as long as the voice quality is likely to be acceptable. Voice quality is measured and maintained to be at an acceptable level. If voice quality degrades below an acceptable level the design allows seamless call hand-off between the 802.11 and a CDMA 1xRTT network, for example.

Abstract: Los datos de computadoras son transferidos entre una red de acceso de radio de tipo CDMA y una infraestructura de núcleo de GSM mediante un conmutador que actúa en el lado del CDMA como un elemento de PDSN (Packet Data Serving Node, nodo que sirve a datos de paquete) y en el lado GSM como un elemento SGSN (Serving GPRS Service Node, nodo que sirve al GPRS en servicio). Se relevan secuencias de conmutación y pilas (stacks) de protocolo.

Abstract: Shared secret data is used to authenticate and encrypt between a CDMA networ k and a GSM network such that a mobile station having a subscription in a GSM network can roam into a CDMA network and be authenticated to use the CDMA network and have messages encrypted without having a CDMA subscription. The goal of authenticating a GSM subscriber in a CDMA network using GSM authentication credentials is achieved by substituting a key Kc as SSD-A and messages are encrypted substituting Kc as SSD-B using a CAVE algorithm.

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: An apparatus and method of mapping a short message service (SMS) information from a first communications system to a corresponding message in a second, different cellular system is claimed. SMS information having a format required by the first communication system is received. The SMS information is mapped into a format required by the second communication system. Additional information is appended, if necessary, or information is removed as being extraneous information, if necessary, as required by the second communication system.

Abstract: Computer data is transferred between a CDMA radio access network and a GSM core infrastructure using a switch that acts on the CDMA side as a packet da ta serving node (PDSN) element (30) and on the GSM side as a serving GPRS servi ce node (SGSN) element (32). Switching message sequences and protocol stacks ar e disclosed.
