Abstract
There is disclosed, for use in a wireless network comprising base stations that communicate with mobile stations, a system for controlling the transmission of data in a traffic channel between a base station and a mobile station. The system comprises a radio link protocol (RLP) controller for causing the base station to transmit to the mobile station a first data transfer control message according to a first radio link protocol version, and a timer coupled to the RLP controller for providing the RLP controller an elapsed time after the transmission of the first data transfer control message. The RLP controller, in response to a determination that an acknowledgment message has not been received from the mobile station before the elapsed time has exceeded a maximum value, transmits to the first mobile station a second data transfer control message according to a second radio link protocol version.
