1. A method for conveying packet data between a mobile station and a GSM network, comprising:
- (a) receiving within a base station subsystem, from the mobile station, communications over a code division multiple access (CDMA) air interface between the mobile station and the base station subsystem, wherein the base station subsystem includes a global system for mobility/code division multiple access (GSM-CDMA) radio link control layer in which operation is adapted to support a GSM general packet data service (GPRS) logic link control layer and general mobility management and session management protocol layer;
(b) emulating within the GSM-CDMA radio link control layer the operation of a global system for mobility/time division multiple access (GSM-TDMA) radio link control layer in response to the received communications; and
(c) providing communications between the base station subsystem and a GSM service node that performs general packet data service logic link control functions and general mobility management and session management protocol layer functions.

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.
