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 data serving node (PDSN) element and on the GSM side as a serving GPRS service node (SGSN) element. Switching message sequences and protocol stacks are disclosed.
Claims29
A switch for supporting wireless communication, comprising:
- a first element communicating with a code division multiple access (CDMA) radio access network (RAN) using CDMA protocol;
- and
- a second element communicating with a GSM core infrastructure using GSM protocol, the first and second elements communicating with each other, whereby use of the CDMA RAN with the GSM core infrastructure is facilitated.
A method for facilitating the use of a CDMA RAN with a GSM core infrastructure, comprising at least one of:
- terminating point-to-point protocol (PPP) framing from the CDMA RAN and sending Internet Protocol (IP) to the GSM core infrastructure in response to selection of IP by a user of a CDMA mobile station communicating with the CDMA RAN;
- and
- initiating packet data protocol (PDP) context activation including specifying at least one access point name from the CDMA mobile station.
A method for facilitating the use of a CDMA RAN with a GSM core infrastructure, comprising at least one of:
- terminating point-to-point protocol (PPP) framing from the CDMA RAN and sending Internet Protocol (IP) to the GSM core infrastructure in response to selection of IP by a user of a CDMA mobile station communicating with the CDMA RAN;
- and
- initiating packet data protocol (PDP) context activation including specifying at least one access point name from a GSM home location registry (HLR).
A wireless data communication system, comprising:
- a CDMA RAN;
- a GSM core infrastructure;
- and
- at least one switch interconnecting the CDMA RAN and GSM core infrastructure, the switch receiving and transmitting computer data using CDMA protocol to the CDMA RAN, the switch receiving and transmitting computer data using GSM protocol to the GSM core infrastructure.
A method for facilitating the use of a CDMA RAN with a GSM core infrastructure, comprising selecting packet data protocol (PDP) context as IP or PPP without changing a CDMA standard.
