For this reason, a mobile communication terminal to be tested is connected to a test apparatus that operates as a pseudo base station that simulates the function of an actual base station, and communication is performed between the test apparatus and the mobile communication terminal. We are conducting a test to confirm the contents.

  Further, in the 3rd Generation Partnership Project (3GPP) that creates a standard for wireless communication, a carrier aggregation (Carrier Aggregation) technique is introduced in the LTE-A (Long Term Evolution-Advanced) standard. This carrier aggregation is intended to improve the transmission speed by performing communication using a plurality of LTE carriers simultaneously.

  In carrier aggregation, communication is performed using a plurality of LTE carriers called component carriers (hereinafter also referred to as “CC”). In carrier aggregation, transmission between a mobile communication terminal and a base station and one primary component carrier (hereinafter also referred to as “PCC”) that is a CC necessary for the mobile communication terminal to maintain a connection with the base station. Communication is performed with one or more secondary component carriers (hereinafter also referred to as “SCC”), which are CCs used to improve speed.

[First Embodiment]
In FIG. 1, a mobile terminal test apparatus 1 according to the first embodiment of the present invention is configured to transmit and receive radio signals to and from a mobile terminal 2 via a coaxial cable or the like as a pseudo base station.

A signal is transmitted, and the radio signal processing unit 10 is caused to transmit a radio signal suitable for the test condition. In addition, the call processing units 12-0 and 1 transmit and receive radio signals to and from the mobile terminal 2 via the radio signal processing unit 10 to establish a call connection suitable for the test conditions as the component carrier. Or call control as a component carrier corresponding to the test conditions. Further, the call processing units 12-0 and 1 transmit a setting signal to the radio signal processing unit 10 according to the set parameters such as a multiplexing method, and transmit a radio signal suitable for the test condition to the radio signal processing unit 10. Let

  The call processing units 12-0 and 1 include a first cell unit 121 and a second cell unit 122 that operate as component carriers. The first cell unit 121 can operate as PCC or SCC, and the second cell unit 122 operates only as SCC. The first cell unit 121 receives a reception signal from the mobile terminal 2 and outputs necessary information to the second cell unit 122.

  CC parameters corresponding to the first cell unit 121 and the second cell unit 122 can be individually set in the radio signal processing unit 10 via the radio hardware control unit 11. In the present embodiment, the case where one second cell unit 122 is provided is shown, but a plurality of second cell units 122 may be provided.

  The radio signal measurement unit 13 is connected to the radio signal processing unit 10, measures the transmission / reception level and throughput of the radio signal transmitted / received by the radio signal processing unit 10, and outputs the measurement result to the control unit 15. . The control unit 15 stores the measurement result from the wireless signal measurement unit 13 in a hard disk or the like in association with time information and the like, and causes the user interface unit 14 to display and output the log as a log according to a user request. It is supposed to be.

  The user interface unit 14 includes an input unit 141 that receives an operation input from a user, and a display unit 142 that displays a CC parameter setting screen, a measurement result of the wireless signal measurement unit 13, and the like. The input unit 141 includes a touch pad, a keyboard, a push button, and the like. The display unit 142 is configured by a liquid crystal display device or the like.

  The control unit 15 is configured by a computer unit including a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a hard disk device, and an input / output port (not shown).

  The ROM and hard disk device of the control unit 15 store programs for causing the computer unit to function as the control unit 15 together with various control constants and various maps. That is, the computer unit functions as the control unit 15 when the CPU executes a program stored in the ROM and the hard disk device.

  The input / output port of the control unit 15 is connected to the wireless hardware control unit 11, the call processing units 12-0 and 1, the wireless signal measurement unit 13, and the user interface unit 14, and the control unit 15 and each unit transmit and receive signals. It can be done.

  In this embodiment, the wireless hardware control unit 11, the call processing units 12-0 and 1 and the wireless signal measurement unit 13 are processed by a processor such as a DSP (Digital Signal Processor) programmed to execute each process. Each is composed. The wireless signal processing unit 10 is configured by a communication module.

  The control unit 15 transmits the setting signal to the wireless hardware control unit 11 based on the parameters set according to the parameter setting screen displayed on the display unit 142, and the frequency of the wireless signal transmitted and received by the wireless signal processing unit 10 And the wireless signal measuring unit 13 performs measurement. In addition, the control unit 15 notifies the set parameters to the call processing units 12-0 and 1 and establishes communication of the component carrier that conforms to the set parameters.

  Further, the control unit 15 transmits a signal to the wireless hardware control unit 11 and the call processing units 12-0 and 1 in accordance with the instruction input to the input unit 141 to perform test call control and the like. It has become.

  Specifically, first, CC parameters used for the test are set by the user. When the parameter setting function is selected by the operation of the input unit 141 by the user, the control unit 15 displays a parameter setting screen on the display unit 142, for example, and sets parameters such as the multiplexing method and channel bandwidth of each CC. (Including the arrangement order information of a plurality of CCs to be used). At this time, the control unit 15 makes it possible to set CCs for the first cell unit 121 and the second cell unit 122 of the call processing units 12-0 and 12 that can be used.

  The user sets parameters for each CC in accordance with the target test. The control unit 15 stores the set parameters for each CC, for example, in the hard disk device, notifies the call processing units 12-0 and 1 of the parameters, and the call processing units 12-0 and 1 according to the set parameters. To be able to control.

  The control unit 15 needs to use a plurality of call processing units 12-0 and 1 having a set number of CCs (in the configuration in which each cell unit is two as shown in FIG. 1) When the SCC of a multiplexing scheme different from the CC multiplexing scheme set as the PCC is set, it is determined whether or not CC allocation is possible.

  The control unit 15 assigns the set plurality of CCs to the plurality of call processing units 12-0 and 12-1. At this time, CCs having at least the same multiplexing method as the PCC multiplexing method are allocated to the call processing units 12-0 and 1 (one call processing unit in the present invention). As a standard operation, the cell processing units 12-0 and 1 are set in the order of each cell unit in the order of CCs set by the user (12-0 121 → 122 → 12-1). 121 → 122).

  The control unit 15 notifies the call processing units 12-0 and 1 of the PCC and SCC allocation information and the parameters of each CC. At this time, each call processing unit 12-0 and 1 is notified of allocation information and parameters of all CCs as well as those allocated to itself. Note that only the information assigned to each call processing unit 12-0, 1 may be notified. Here, it is assumed that 3 CCs are set, 2 CCs are assigned to one call processing unit 12-0, 1 and 1 CCs are assigned to the other call processing unit 12-0, 1.

  The call processing units 12-0 and 1 (one call processing unit in the present invention; here, 12-0) has two CCs allocated to itself and is different from the CCC multiplexing method. When there is the same CC as the PCC multiplexing scheme, the CC parameter of the same multiplexing scheme as the PCC multiplexing scheme is set in the first cell unit 121, and the second cell unit 122 is multiplexed differently from the PCC multiplexing scheme. Set the CC parameters of the system.

  The call processing units 12-0 and 1 (another call processing unit in the present invention; 12-1 here) has one CC assigned to itself, and the multiplexing scheme of the CC and the PCC When the multiplexing method is the same, the assigned CC parameter is set in the first cell unit 121.

  Further, the call processing unit 12-1 has one CC assigned to itself, and if the CC multiplexing method and the PCC multiplexing method are different, the first cell unit 121 has the PCC multiplexing method. Is set so that the signal from the mobile terminal 2 can be received, and the parameter of the assigned CC is set in the second cell unit 122 to enable signal transmission of the SCC. The call processing unit 12-1 sets the radio signal processing unit 10 so that the signal from the mobile terminal 2 is received by the first cell unit 121 and does not transmit the signal of the first cell unit 121.

  Here, the configuration of the call processing units 12-0 and 1 will be described. Usually, the call processing units 12-0 and 1 are configured on the same board, and therefore, another call processing unit 12-1 is assumed to be used in combination with PCC and SCC. Therefore, the call processing unit 12-1 uses the first cell unit 121 and the second cell unit 122 as the SCC, but moves if the first cell unit 121 is not the same multiplexing method as the PCC multiplexing method. The feedback signal from the terminal 2 cannot be received and communication cannot be performed.

  Further, the control information transmitted from each CC to the mobile terminal 2 will be described. Each CC transmits control information for receiving a signal from the base station to the mobile terminal 2. The content of control information transmitted from the SCC differs depending on the multiplexing method. Therefore, if an SCC having a multiplexing scheme different from the PCC of 12-0 is assigned to the first cell unit of the call processing unit 12-1, incorrect control information is transmitted to the mobile terminal 2.

  For this reason, the SCC of the same multiplexing method as the PCC multiplexing method is used so that the call processing unit 12-1 can also receive a feedback signal from the mobile terminal 2 (and prevent transmission of erroneous control information). assign. Specifically, the first cell unit 121 of the call processing unit 12-1 can receive a signal from the mobile terminal 2, and the second cell unit 122 transmits an SCC signal.

  For example, as shown in FIG. 2, when the user sets the FDD CC as the PCC and the two TDD CCs as the SCC in this arrangement order (assigned in order from the first cell part of the call processing unit 12-0) If the TDD is set in the first cell unit 121 of the call processing unit 12-1, the signal from the mobile terminal 2 cannot be received. Therefore, the first cell unit 121 is set to be able to receive a signal from the mobile terminal 2 as an FDD, and the second cell unit 122 is set to be a TDD and the function as the SCC2 is executed.

  After setting such parameters, the user connects the mobile terminal test apparatus 1 and the mobile terminal 2 by wire, and turns on the mobile terminal 2 to perform location registration, so that the mobile terminal test apparatus 1 side To check if the location registration was successful.

  In a state where the location registration is performed, the control unit 15 performs a call connection operation by an operation of the input unit 141 by the user, and the call processing unit 12-0 corresponding to the CC designated by the user is connected to the call processing unit 12-0. Send an instruction to make a call connection.

  When the user performs an operation to execute a transmission test by operating the input unit 141 while the call connection is made, the control unit 15 transmits an instruction to execute the test to the radio signal measuring unit 13 and transmits the transmission signal. Let the test be done. When receiving the test result information from the wireless signal measuring unit 13, the control unit 15 stores the result in the hard disk device as a log and causes the display unit 142 to display the result and the like.

  In addition, when a connection test is performed by a user operating the input unit 141 in a state in which a call connection is made, the control unit 15 causes the call processing unit 12-0 corresponding to the call connected CC to be called. Send a test execution instruction to test the received signal. Upon receiving the test result information from the call processing unit 12-0, the control unit 15 stores the result as a log in the hard disk device and causes the display unit 142 to display the result and the like.

  A parameter setting process performed by the call processing unit 12-1 of the mobile terminal test apparatus 1 according to the present embodiment configured as described above will be described with reference to FIG.

  As shown in FIG. 3, the call processing unit 12-1 determines whether a CC of a multiplexing scheme different from the multiplexing scheme of the PCC is based on the PCC and SCC allocation information notified from the control unit 15 and the parameters of each CC. It is determined whether or not it is necessary to change the parameters to the first cell unit 121 and the second cell unit 122 (step S11).

  When it is determined that there is no need to change the parameters to the first cell unit 121 and the second cell unit 122, the call processing unit 12-1 performs normal parameter setting that sets the parameters according to the set parameters (steps). S14), the process is terminated.

  On the other hand, when it is determined that the parameter change to the first cell unit 121 and the second cell unit 122 is necessary, the call processing unit 12-1 sets the PCC multiplexing method in the first cell unit 121. Then, the parameter of the assigned CC is set in the second cell unit 122, and the changed parameter is set (step S12).

  Next, the call processing unit 12-1 sets the radio signal processing unit 10 so that the signal from the mobile terminal 2 is received by the first cell unit 121 and does not transmit the signal of the first cell unit 121. The signal input / output to be changed is changed (step S13), and the process is terminated.

  Thus, in the above-described embodiment, when the SCC having a multiplexing scheme different from the PCC multiplexing scheme is assigned, the call processing unit 12-1 sets the SCC parameter in the second cell unit 122, and The first cell unit 121 is set to the same multiplexing method as the PCC multiplexing method, and the first cell unit 121 receives a reception signal from the mobile terminal 2.

  As a result, the call processing unit 12-1 can also receive a signal from the mobile terminal 2, and can perform a carrier aggregation test in which CC multiplexing methods are mixed.

  Further, the call processing unit 12-1 transmits a CC transmission signal from the second cell unit 122.

  As a result, the call processing unit 12-1 can also transmit / receive signals to / from the mobile terminal 2, and can perform a carrier aggregation test in which CC multiplexing methods are mixed.

  Also, the call processing unit 12-0 to which a CC having the same multiplexing scheme as the PCC multiplexing scheme is assigned causes the first cell unit 121 to operate as a CC having the same multiplexing scheme as the PCC multiplexing scheme.

  As a result, the call processing unit 12-0 can also transmit and receive signals to and from the mobile terminal 2, and a carrier aggregation test in which CC multiplexing methods are mixed can be performed.

  Here, a modified embodiment will be described with reference to FIG. FIG. 4 shows a mode in which CCs to be set are 4 CCs (FDD, TDD, TDD, TDD), and the number of cell parts of the call processing units 12-0 and 12-1 is 2 and 3, respectively. ing. The call processing unit 12-1 sets the assigned SCCs 2 and 3 in the second cell unit 122, sets the first cell unit 121 to the same multiplexing scheme as that of the PCC, and uses the first cell unit 121 from the mobile terminal. A feedback signal is received.

  That is, according to the present invention, when normal allocation setting is performed, the allocation of the call processing unit 12-1 to the first cell unit 121 is different from the multiplexing method of the first cell unit 121 (PCC) of the call processing unit 12-0. In such a case, the SCC may be set in the second cell unit 122 while avoiding setting the SCC having a different multiplexing method in the first cell unit 121 of the call processing unit 12-1. Therefore, the type of multiplexing method assigned to the call processing unit 12-1 side is not limited. For example, the present invention can be applied even when 4CC set in the mode of FIG. 4 is FDD, TDD, TDD, or FDD. Moreover, since it is such a technical idea, the number of cells of the call processing unit 12-0 may be one or more (a configuration having at least the first cell unit 121).

[Second Embodiment]
Next, a second embodiment will be described with reference to FIG. In the first embodiment described above, the arrangement of the SCC is changed in one call processing unit 12-1. However, in the present embodiment, a plurality of call processing units 12-0 and 1 are spanned. Change the configuration. This embodiment is the same as the embodiment shown in FIG. 2 in the number of CCs to be set and the call processing unit configuration (number of cells). The difference is that the 3CC multiplexing method to be set is FDD, FDD, and TDD.

  The control unit 15 notifies the call processing units 12-0 and 1 of all information set this time (arrangement of all CCs, allocation information of all CCs, setting parameters of all CCs, etc.). Based on the notified information, SCC of a multiplexing method different from PCC is not assigned to the first cell unit 121 of the call processing unit 12-1. The call processing unit 12-0 sets PCC (FDD) in the first cell unit 121 and sets SCC2 (TDD) in the second cell unit 122. On the other hand, the call processing unit 12-1 sets SCC 1 (FDD) in the first cell unit 121. As a result, the multiplexing method of the first cell unit 121 of the call processing unit 12-1 is the same as the multiplexing method of the first cell unit 121 of the call processing unit 12-0, and the call processing unit 12-1 Unit 121 can receive a feedback signal from the mobile terminal.

  In the second embodiment, it is assumed that the call processing unit 12-0 includes a plurality of cell units (including a second cell unit), while the call processing unit 12-1 includes a cell unit. One or more parts may be provided (at least the first cell part may be provided). Also, it is assumed that the number of CCs (including PCC) of the same multiplexing scheme as PCC among all CCs is equal to or greater than the number of multiple call processing units 12-0 and 1.

  Although the embodiments of the present invention have been disclosed above, it will be apparent to those skilled in the art that changes can be made without departing from the scope of the present invention. All such modifications and equivalents are intended to be included in the following claims.
