  The combiner 19 combines the radio signals transmitted from the pseudo base station units 18-1 to 18-3 and transmits them to the mobile communication terminal 2. The combiner 19 transmits the signal received from the mobile communication terminal 2 to each of the pseudo base station units 18-1 to 18-3.

  Here, the mobile terminal test apparatus 1 is configured by a computer apparatus (not shown) provided with a communication module for communicating with the mobile communication terminal 2. Each of the computer devices includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk device, an input / output port, and a touch panel (not shown).

  The ROM and the hard disk device of this computer device store a program for causing the computer device to function as the mobile terminal test device 1. That is, when the CPU executes a program stored in the ROM using the RAM as a work area, the computer apparatus functions as the mobile terminal test apparatus 1.

The scenario generation unit 15 generates broadcast information, sequence information, and the like based on the information received from the control unit 14, and stores the information in the storage unit 16 in association with the identification information as a scenario of the pseudo base station.

  Further, when performing a test using a plurality of base stations, the user sets the cell arrangement of the base stations. The control unit 14 transmits the set cell arrangement information to the scenario generation unit 15 to generate a cell arrangement scenario. Based on the cell arrangement information received from the control unit 14, the scenario generation unit 15 automatically generates neighboring cell information of the broadcast information of the pseudo base station scenario that is set to be used, and the cell arrangement scenario Are stored in the storage unit 16 in association with the scenario and identification information of the pseudo base station used.

  After creating such a scenario, the user connects the mobile terminal test apparatus 1 and the mobile communication terminal 2 by wire, and selects a scenario of a pseudo base station to be used or a scenario of cell arrangement.

  The control unit 14 notifies the scenario processing unit 17 of the identification information of the selected pseudo base station scenario or cell arrangement scenario, and causes the scenario processing unit 17 to execute the scenario.

  The scenario processing unit 17 reads the scenario associated with the notified identification information from the storage unit 16, and transmits the contents of the broadcast information to the pseudo base station units 18-1 to 3 based on the read scenario and the transmission information in the location registration process. To start the operation as a pseudo base station.

  Further, when the scenario processing unit 17 starts executing the scenario, the scenario processing unit 17 notifies the control unit 14 of the state of the pseudo base station units 18-1 to 18-3 that are executing the scenario.

  When the control unit 14 receives information on the status of the pseudo base station units 18-1 to 18-3 from the scenario processing unit 17, the display control unit 13 causes the display unit 12 to display the status of the pseudo base station units 18-1 to 18-3 and the mobile communication terminal. 2 connection status etc. are displayed.

  After selecting the scenario of the pseudo base station to be used, the user performs location registration by turning on the power of the mobile communication terminal 2, and confirms whether the location registration has been normally performed on the mobile terminal test apparatus 1 side. To do.

  When the position registration is performed and the operation of the sequence set in the scenario of the pseudo base station is performed by the operation of the operation unit 11 by the user, the control unit 14 performs the sequence specified by the scenario processing unit 17. Is instructed to execute.

  When the scenario processing unit 17 receives an instruction to execute a sequence from the control unit 14, the scenario processing unit 17 transmits a radio signal from each of the pseudo base station units 18-1 to 18-3 based on the information of the designated sequence, or the mobile communication terminal 2. For example, the pseudo base station units 18-1 to 18-3 transmit radio signals corresponding to the radio signals received from.

  In such a mobile terminal test apparatus 1, when setting of MFBI information is selected by operating the operation unit 11, the control unit 14 displays a screen as shown in FIG. 2 on the display unit 12 by the display control unit 13. The MFBI information is set by operating the operation unit 11.

  In FIG. 2, a band drop-down list 101 is for setting a band to be used in a simulated base station. The control unit 14 displays, as MFBI check boxes 102-0 to 102-3, bands that can be designated as MFBI among the bands selected from the band drop-down list 101.

  In addition, the control unit 14 causes the band display unit 105 to display the position on the frequency of the frequency band of the band selected from the band drop-down list 101, for example, with a color. Further, the control unit 14 causes the MFBI display unit 106 to know the positional relationship in frequency with the frequency band of the band displayed on the band display unit 105 about the position of the frequency band of the band that can be designated as MFBI. Display. In other words, the control unit 14 displays so that the frequency band of the band selected to be used in the simulated base station and the frequency of the band that can be specified in the MFBI can be recognized.

  FIG. 2 shows a case where band 5 is selected as a band to be used. The frequency band of the band 5 is determined as shown in FIG. 3 according to the LTE standard, and bands 18, 19 and 26 as shown in FIG. The control unit 14 displays the bands 18, 19, and 26 on the MFBI display unit 106 as bands that can be designated as MFBI.

  The MFBI check boxes 102-0 to 102-3 are used to select a band to be specified in the MFBI. When the MFBI check box 102-0 is checked, the control unit 14 sets the bands 18, 19, and 26 as MFBI. When the MFBI check boxes 102-1 to 102-3 are checked, the control unit 14 individually sets the bands 18, 19, and 26 to MFBI.

  For the band selected by the MFBI check boxes 102-0 to 102-3, the control unit 14 displays the frequency band of the MFBI display unit 106 with an image different from the band not selected, for example, with a color. Thereby, the frequency band of the band selected by MFBI can be visually confirmed.

  In FIG. 2, since the MFBI check boxes 102-1 and 102-1 are checked and the bands 18 and 19 are selected, the frequency bands of the bands 18 and 19 of the MFBI display unit 106 are displayed in color, but the band 26 The frequency band of is not colored. Note that if the color of the frequency band of the band display unit 105 and the color of the frequency band of the MFBI display unit 106 are different colors, it is easy to distinguish between the band to be used and the band of MFBI.

  The bandwidth drop-down list 103 is used to set the frequency band width used for communication in the simulated base station. Whether the band width corresponds to each band is determined as shown in FIG. The bandwidth “3 MHz” shown in FIG. 2 corresponds to the band 5, but does not correspond to the bands 18 and 19. As described above, when the bandwidth selected in the bandwidth drop-down list 103 does not correspond to the band selected in the MFBI check boxes 102-0 to 102-3, the control unit 14 corresponds to the corresponding band of the MFBI display unit 106. The bandwidth warning display 111 is displayed in the portion.

  The center frequency slider 104 is for setting the center frequency of the frequency band to be used. The control unit 14 decreases the center frequency as the center frequency slider 104 moves to the left, and increases the center frequency as the center frequency slider 104 moves to the right.

  The control unit 14 causes the frequency display unit 107 and the channel number display unit 108 to display the frequency and channel number corresponding to the position of the center frequency slider 104.

  In addition, the control unit 14 sets the center frequency bar 109 and the frequency band frame 110 at a frequency position corresponding to the position of the center frequency slider 104 in the portion displaying the frequency band of the band display unit 105 and the MFBI display unit 106. Display.

  In response to the movement of the center frequency slider 104, the control unit 14 moves the center frequency bar 109 to a frequency position corresponding to the position of the center frequency slider 104, and the frequency band frame 110 also moves together with the center frequency slider 104. Let The control unit 14 displays the frequency band frame 110 by changing the width corresponding to the bandwidth selected from the bandwidth drop-down list 103.

  As shown in the band 18 in FIG. 2, the center frequency specified by the center frequency slider 104 falls within the frequency band of the band, but either of the ends of the bandwidth selected from the center frequency by the bandwidth drop-down list 103 is selected. When is out of the frequency band of the band, the control unit 14 causes the band out-of-band warning display 112 to be displayed on the corresponding band portion of the MFBI display unit 106.

  2, when the center frequency specified by the center frequency slider 104 does not fall within the frequency band of the band, the control unit 14 places the center frequency in the corresponding band portion of the MFBI display unit 106. The out-of-frequency band warning display 113 is displayed.

  In this way, the frequency band of the band to be used and the frequency band of the band that can be designated as MFBI are displayed on the band display unit 105 and the MFBI display unit 106, so the overlapping portion of the frequency of each band is visually confirmed. Therefore, MFBI can be set easily.

  In addition, since the center frequency bar 109 and the frequency band frame 110 are displayed so as to be superimposed on the display of the frequency band of each band, how the center frequency and the frequency bandwidth to be used cover each band. Can be visually confirmed, and MFBI can be easily set.

  Also, since the width of the frequency band frame 110 is changed according to the bandwidth selected in the bandwidth drop-down list 103, the frequency bandwidth can be visually confirmed, and the MFBI setting can be changed. It can be done easily.

  In addition, since the MFBI check boxes 102-0 to 102-3 indicate the bands that can be set by the MFBI corresponding to the frequency band selected from the band drop-down list 101, the band can be set without checking the MFBI band. MFBI can be easily set.

  In addition, when the bandwidth selected in the bandwidth drop-down list 103 is set to MFBI and the selected band does not support the bandwidth warning display 111, the bandwidth is not supported. Can be easily confirmed.

  The center frequency specified by the center frequency slider 104 is within the frequency band of the band, but either one of both ends of the bandwidth selected from the center frequency to the band drop-down list 103 is from the band frequency band. When the frequency band is out, the band out-of-band warning display 112 is displayed, so that it can be easily confirmed that the frequency band to be used is out of the frequency band of the band.

  When the center frequency specified by the center frequency slider 104 is not within the band frequency band, the center frequency band out-of-band warning display 113 is displayed, so the center frequency is outside the band frequency band. This can be easily confirmed.

  2 shows a screen for setting a downlink (link from the mobile terminal test apparatus 1 to the mobile communication terminal 2), but an uplink (link from the mobile communication terminal 2 to the mobile terminal test apparatus 1). ) Can also be implemented in the same way.

  The control unit 14 generates scenario information about the MFBI information set on the screen as shown in FIG. 2, for example, the scenario information of the pseudo base station including the band to be used, the center frequency, the bandwidth, the band set to the MFBI, and the like. 15 to send.

The message displayed on the unit 12 is displayed for selecting a scenario of the pseudo base station for setting the cell arrangement.

  When the scenario of the pseudo base station that sets the cell arrangement is selected by the user's operation on the operation unit 11, the control unit 14 selects, for example, the cell corresponding to the scenario of the pseudo base station selected on the display unit 12. The icon is displayed, and the position of the icon is changed by the user's operation on the operation unit 11, and the cell arrangement is set according to the position of the icon.

  When the completion of the cell arrangement setting is selected by the user's operation on the operation unit 11, the control unit 14 determines the cell adjacency relationship from the position of the icon displayed on the display unit 12, and displays the cell arrangement information. The information of the cell arrangement and the identification information of the scenario of the selected pseudo base station are transmitted to the scenario generation unit 15. In addition, the control unit 14 stores the cell arrangement information and the identification information of the selected pseudo base station scenario as the cell arrangement scenario in the storage unit 16 so as to be identifiable by the identification information input by the user, for example.

  When the scenario generation unit 15 receives the cell arrangement information and the identification information of the selected pseudo base station scenario from the control unit 14, the scenario generation unit 15 transmits the notification information of the pseudo base station scenario based on the cell arrangement information. 151.

  The broadcast information generating unit 151 generates and sets related broadcast information, for example, MFBI information, for example, in System Information Block Type 5 based on the cell arrangement information.

  Also, the broadcast information generation unit 151 is configured to use System Information Block Type 19 (W-CDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access)), System Information 2 quarter (GSM (Global System for Mobile communications) / GPRS (General Packet Radio Service)), Alternative Technologies Information Message (CDMA2000 1X), OtherRATNeighbourList Message (CDMA2000) 1x EV-DO) etc. to generate and set MFBI information.

  The scenario generation unit 15 changes the pseudo base station scenario stored in the storage unit 16 based on the generated notification information.

  When using the scenario generated in this way, the user selects, for example, a scenario setting by operating the operation unit 11.

  When the scenario of the pseudo base station is selected by the user's operation on the operation unit 11, the control unit 14 transmits identification information of the selected scenario of the pseudo base station to the scenario processing unit 17.

  When the scenario processing unit 17 receives the identification information of the pseudo base station scenario from the control unit 14, the scenario processing unit 17 reads the scenario of the pseudo base station corresponding to the identification information from the storage unit 16 and stores the pseudo base station scenario 18-1 in the pseudo base station unit 18-1. Make the process according to the scenario.

  In addition, when a cell placement scenario is selected by a user operation on the operation unit 11, the control unit 14 transmits identification information of the selected cell placement scenario to the scenario processing unit 17.

  When the scenario processing unit 17 receives the identification information of the cell arrangement scenario from the control unit 14, the scenario processing unit 17 reads the cell arrangement scenario corresponding to the identification information from the storage unit 16, and the scenario of the pseudo base station associated with the cell arrangement scenario. The scenario of the pseudo base station is read out from the identification information, and the pseudo base station units 18-1 to 18-3 corresponding to the number of scenarios of the pseudo base station are caused to perform processing according to the scenario of the pseudo base station.

  When the scenario is set in this way and the processing by the pseudo base station units 18-1 to 18-3 is started, the pseudo base station units 18-1 to 18-3 receive information on the simulated base station and the connected mobile communication. Information on the terminal 2 is transmitted to the scenario processing unit 17.
