Data communication system and method for determining round-trip-time adaptable to communication environment

摘要

A data communication system adapting a radio link protocol (RLP) includes at least one base transceiver station (BTS) for communicating with a plurality of subscriber stations (SSs); and a base station controller (BSC) for setting radio link protocol (RLP) round-trip-time (RTT) value for the at least one BTS under its control and transmitting each value to the at least one BTS, wherein the at least one BTS transmits its unique RTT value received from the BSC to the SS when handoff of the SS occurs.
