In a GSM mobile wireless telecommunications system, a method for conveying
signaling between a mobile station and a base station 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, which produces an IS-95
message for transmission.
