PURPOSE: A radio resource simulator is provided to perform a test with high reliability and easily develop a software by performing the test of the software under various hardware environment. CONSTITUTION: An RRC(Radio Resource Control) module(101) defines an interface with an RLC(Radio Link Control) module(102) and a MAC(Medium Access Control) module(103) as a message type designated in the CCITT(International Telegraph and Telephone Consultative Committee) recommendation, defines an NAS(Non-Access Stratum) interface as the message type designated in the CCITT recommendation, and control radio resources. The RLC module(102) measures the performance of a flow control algorithm through buffer management. The MAC module(103) performs the mapping of a transport channel and a logic channel, defines an interface for control information with the RRC module(101) and an interface for user information with the RLC module(102), and maps a lower transport channel to an ATM(Asynchronous Transfer Mode) connection. An RTDB(Real Time DataBase)(104) stores radio resources in real time. A data collecting and transmitting module(105) collects and transmits data. A GUI(Graphic User Interface) module(106) performs a GUI and a data interface. A microprocessor(108) controls an entire operation for a radio resource test.
