Abstract:
PURPOSE: A mobile station simulator system for executing a handoff protocol function, an apparatus for testing handoffs using the same and a method for operating the same are provided to execute an effective handoff call test by verifying an inter base station handoff associated radio protocol function under the test environment of a CDMA mobile system and supplying analysis data for test procedures and test results to a tester. CONSTITUTION: A soft handoff test apparatus using a mobile station simulator system consists of two base stations(301,302), a base station controller(316), and mobile station simulators(309,312,313). Each base station(301,302) is composed of a transmit-receive function block(303,304), a call processing block(305,306), and a network access unit(307,308). Each transmit-receive function block(303,304) transmits and receives wireless protocol messages through a CDMA channel. Each call processing block(305,306) executes a handoff call processing function. Each network access unit(307,308) transmits call processing messages to the base station controller(316). The function blocks of each base station(301,302) are physically connected through each cell bus(314,315) one another. Also each mobile station simulator front end system(312,313) communicates with the function blocks of each base station(301,302) through each cell bus(314,315). The mobile station simulator rear end system(309) provides a series of analysis results associated with call tests to a test operator.
