Abstract:
A method for conveying packet data from a CDMA mobile station to a GSM network, including communicating with a GSM service node to establish a data link from the mobile station to the network via a radio communications base station. The packet data are conveyed between the mobile station and the base station over a CDMA air interface and are then transferred over the link between the base station and the network.
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 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.

Abstract:
In a GSM mobile wireless telecommunications system, a method for broadcastin g messages over a CDMA air interface includes conveying a message to a base station substantially in accordance with a GSM cell broadcast service protocol, and transmitting the message to a mobile station over the CDMA air interface. The message is transmitted substantially in accordance with a CDM A transmission standard, preferably the IS-95B standard.
Abstract:
A mobile wireless telecommunication system includes base stations of a first type operating according to a first air interface, and base stations of a second type operating according to a second air interface. Methods and apparatus are provided for handing over a mobile station in the system from a first base station, which is of the first type, to a second base station, which is of the second type. A communications link is established over the first air interface between the mobile station and the first base station. Data are received from the mobile station responsive to a signal received by the mobile station over the second air interface from the second base statio n, substantially without breaking the communications link with the first base station. The mobile station is handed over from the first to the second base station responsive to the data received therefrom.

Abstract:
In a GSM mobile wireless telecommunications system (20), a method for conveying data from terminal equipment (46) to a network (48) via a CDMA air interface, including receiving the data as input from the terminal equipment (46) and transmitting the data at a CDMA data transfer rate over the CDMA air interface. The data are transferred to the network (48) over a GSM A-interface using a GSM circuit switched data protocol.
