AN APPARATUS FOR TESTING BASE STATION OF MOBILE COMMUNICATION SYSTEM AND A ETHOD FOR CONSTRUCTING ITS FUNCTIONS

摘要

The present invention, in the configuration of the transmission and reception test path for configuring the base station test apparatus, a base station having a structure that can be commonly applied to a duplex type system in which the transmission and reception antennas are separated and the transmission and reception are configured through the same antenna. A test apparatus and a method for configuring a function for each path of a base station test apparatus of a mobile communication system. That is, the present invention relates to a structure of a test apparatus for checking abnormal lubrication of a base station system and a configuration method thereof.;The present invention, in the test apparatus of the base station separated from the transmission and reception in the mobile communication system,;TX-PATH comprising three antennas;;RX-PATH_A including three antennas;;RX-PATH_B including three antennas;;A first RFIU connected with the TX-PATH;;A second RFIU connected with the RX-PATH_A;;A third RFIU connected with the RX-PATH_B;;First three-way couplers connected in parallel with the first to third RFIUs, respectively;;The three-way coupler through a variable attenuator capable of controlling path loss by external control,;Switch control / variable attenuator controls and;SP3T switches connected in parallel with each of the first to third RFIUs;;Parallel connected PTMU; And;It is characterized in that it comprises the MXBB to supply the +27 volts to the system +5 volts and -12 volts.;In still another aspect of the present invention, in a duplex base station test apparatus for a mobile communication system,;With three antennas $\alpha$ -Sector;;With three antennas $\beta$ -Sector;;With three antennas $\gamma$ -Sector;;remind $\alpha$ A first RFIU associated with the sector;;remind $\beta$ A second RFIU associated with the sector;;remind $\gamma$ A third RFIU associated with the sector;;First three-way couplers connected in parallel with the first to third RFIUs, respectively;;The three-way coupler through a variable attenuator capable of controlling path loss by external control,;Switch control / variable attenuator controls and;SP3T switches connected in parallel with each of the first to third RFIUs;;Parallel connected PTMU; And;It is characterized in that it comprises the MXBB to supply the +27 volts to the system +5 volts and -12 volts.;In still another aspect of the present invention, there is provided a functional configuration method of a base station test apparatus of a mobile communication system.;Applying one sector of the system output to each basic structure of the RFIU;;Sampling the output of the system at the D / C;;Switch connected to the antenna, second three-way coupler, two-way splitter and SP3T;Pass through the switch to TPDB (Transmit Power Detect Board),;Through the first three-way coupler and the variable attenuator in the two-way splitter;Delivering to a Test Mobile (TM); And;Adjusting the RF signal of the transmission and reception path to the appropriate size through the attenuator;Duplex that includes a system and uses both a transmitting and receiving antenna;A first process applied in the case of a system; And;Applying a transmit path and a receive path of the system to the RFIU;;Equally setting signal flows of the transmission and reception paths;;Setting a signal flow of the reception path in a direction opposite to the transmission path; And;This includes the steps of turning the switch on and off according to the configuration of the system.;Is applied to a system using a separate antenna.;With 2nd course;It is characteristic that it is made.
