Description

[Technical Field]

[0001] The present invention relates to a mobile terminal testing device for testing a mobile terminal. [Background technology]

[0002] When developing a mobile terminal such as a mobile phone or data communication terminal, it is necessary to test whether the developed mobile terminal can communicate normally. For this purpose, the mobile terminal to be tested is connected to a test device that operates as a pseudo base station that simulates the functions of an actual base station, and communication is carried out between the test device and the mobile terminal, and the content of this communication is confirmed.

[0003] Additionally, the 3GPP (3rd Generation Partnership Project), which develops wireless communication standards, has introduced carrier aggregation technology into the LTE-A (Long Term Evolution-Advanced) standard, which aims to improve transmission speeds by simultaneously using multiple LTE carriers for communication.

[0004] Carrier aggregation uses multiple LTE carriers called component carriers (hereinafter referred to as CCs) for communication. In carrier aggregation, communication is performed using one primary component carrier (hereinafter referred to as PCC), which is a CC required for a mobile terminal to maintain connection with a base station, and one or more secondary component carriers (hereinafter referred to as SCCs), which are CCs used to improve the transmission speed between the mobile terminal and the base station.

[0005] In carrier aggregation, a combination of frequency bands for carrier aggregation is defined as a band combination, and a mobile terminal that performs carrier aggregation has a predetermined set of frequency band combinations that it can support.

[0006] Patent Document 1 describes that a band combination supported by a mobile terminal is acquired based on UE Capability Information received from the mobile terminal. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2020-137047 Summary of the Invention [Problem to be solved by the invention]

[0008] When testing carrier aggregation, the test equipment must be configured with a combination of frequency bands that the mobile terminal supports.

[0009] As a general rule, a mobile terminal can only connect a call using the band combination notified in the UE Capability Information. Therefore, if the band combination value notified in the UE Capability Information differs from the setting of the test equipment, the call cannot be connected, which reduces the efficiency of the test.

[0010] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a mobile terminal test device that can improve the efficiency of testing by making it possible to check whether a call can be connected using the test device settings before connecting the call. [Means for solving the problem]

[0011] The mobile terminal test device of the present invention is a mobile terminal test device (1) that tests a mobile terminal (10) by simulating a base station for mobile communication, and includes a control unit (6) that acquires UE Capability Information by communication with the mobile terminal, checks whether a band combination set in the device exists in a carrier aggregation band combination list of the UE capability information, and, if the band combination set in the device exists in the carrier aggregation band combination list, causes a display unit (5) to display that call connection is possible.

[0012] With this configuration, the Carrier Aggregation Band Combination List in the UE Capability Information is checked to see if the Band Combination set in the device itself exists, and if the Band Combination set in the device itself exists in the Carrier Aggregation Band Combination List, it is displayed that the call connection is possible. Therefore, it is possible to check whether the call connection is possible with the settings of the test device before connecting the call, thereby improving the efficiency of the test.

[0013] In the mobile terminal test device of the present invention, the control unit changes the display of the portion displayed corresponding to each CC to indicate that the call connection is possible.

[0014] With this configuration, the display of the part corresponding to each CC changes to indicate that the call can be connected, which allows the test equipment settings to be checked before connecting the call, improving test efficiency.

[0015] Furthermore, in the mobile terminal test device of the present invention, the control unit checks whether the band combination set in the device itself exists in the carrier aggregation band combination list every time the parameter setting is changed, and displays whether call connection is possible.

[0016] With this configuration, every time the parameter settings are changed, the Carrier Aggregation Band Combination List is checked to see if the Band Combination set in the device itself exists, and whether call connection is possible is displayed. Therefore, every time the parameter settings are changed, it is clear whether call connection is possible, improving the efficiency of testing.

[0017] Furthermore, the call connection confirmation method of the present invention is a call connection confirmation method for a mobile terminal test device (1) that tests a mobile terminal (10) by simulating a base station in mobile communication, and includes the steps of: acquiring UE Capability Information by communication with the mobile terminal; checking whether a band combination set in the device itself exists in a carrier aggregation band combination list of the UE capability information; and displaying that call connection is possible if the band combination set in the device itself exists in the carrier aggregation band combination list.

[0018] With this configuration, the Carrier Aggregation Band Combination List in the UE Capability Information is checked to see if the Band Combination set in the device itself exists, and if the Band Combination set in the device itself exists in the Carrier Aggregation Band Combination List, it is displayed that the call connection is possible. Therefore, it is possible to check whether the call connection is possible with the settings of the test device before connecting the call, thereby improving the efficiency of the test. [Effects of the Invention]

[Figure 2] FIG. 2 is a diagram showing an example of a call connection confirmation screen of a mobile terminal test device according to an embodiment of the present invention. [Figure 3] FIG. 3 is a flowchart illustrating the procedure of the call connection confirmation process of the mobile terminal test device according to one embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0021] Hereinafter, a mobile terminal test device according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0022] 1, a mobile terminal test device 1 according to an embodiment of the present invention is configured to transmit and receive RF signals to and from a mobile terminal 10 as a pseudo base station via a wired connection such as a coaxial cable. Note that the mobile terminal test device 1 may also transmit and receive RF signals to and from the mobile terminal 10 wirelessly via an antenna.

[0023] The mobile terminal test device 1 includes a pseudo base station unit 2, a scenario processing unit 3, an operation unit 4, a display unit 5, and a control unit 6.

[0024] The pseudo base station unit 2 transmits and receives RF signals to and from the mobile terminal 10 under the control of the scenario processing unit 3. The pseudo base station unit 2 outputs the state of communication with the mobile terminal 10 to the control unit 6.

[0025] In response to instructions from the control unit 6, the scenario processing unit 3 reads out a stored scenario and, based on that scenario, causes the pseudo base station unit 2 to transmit notification information and execute a communication sequence with the mobile terminal 10.

[0026] The operation unit 4 is composed of input devices such as a keyboard, mouse, and touch panel, and outputs the information required for scenario generation that has been input through operation to the control unit 6. The display unit 5 is composed of an image display device such as an LCD display, and displays images for inputting the information required for scenario generation and images showing the status during testing.

[0027] The control unit 6, in accordance with instructions input to the operation unit 4, displays a test scenario creation screen on the display unit 5 and causes the user to input information necessary for generating a test scenario, or generates a test scenario on the test scenario creation screen based on the information input to the operation unit 4. Furthermore, in accordance with instructions input to the operation unit 4, the control unit 6 sends instructions to the scenario processing unit 3 to execute a test based on the test scenario stored in the storage device, or causes the display unit 5 to display the status of the test, etc., based on information such as the status of each layer and the status of communication with the mobile terminal 10 transmitted from the scenario processing unit 3.

[0028] Here, the mobile terminal test device 1 is configured by a computer device (not shown) provided with a communication module for communicating with the mobile terminal 10. This computer device has a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), a storage device such as a hard disk drive, an input / output port, and a touch panel (all not shown).

[0029] The ROM and hard disk drive of this computer device store a program for causing the computer device to function as the mobile terminal test device 1. That is, the CPU executes the program stored in the ROM using the RAM as a working area, causing the computer device to function as the mobile terminal test device 1.

[0030] As described above, in this embodiment, the scenario processing unit 3 and the control unit 6 are configured by a CPU, and the pseudo base station unit 2 is configured by a communication module.

[0031] When testing a mobile terminal 10 in the mobile terminal test device 1 configured as above, the user first creates a scenario to be used for the test. When the user selects a function for creating a scenario by operating the operation unit 4, the control unit 6, for example, displays a scenario creation screen on the display unit 5, and allows the user to set information about the base station to be simulated by the pseudo base station unit 2, the sequence to be executed, and so on.

[0032] The user sets various information for the base station according to the target test. Based on the set information, the control unit 6 generates broadcast information, sequence information, etc., and stores them as a scenario for the pseudo base station in association with the identification information.

[0033] When testing carrier aggregation, a scenario must be set using a combination of frequency bands supported by the mobile terminal 10. The mobile terminal test device 1 of this embodiment checks whether the same band combination as the band set in the mobile terminal test device 1 exists in the Carrier Aggregation Band Combination List of the UE Capability Information that can be acquired from the mobile terminal 10, and if the same band combination as the setting exists, the display unit 5 displays that call connection is possible.

[0034] When checking whether the band set in the mobile terminal test device 1 is included in the band combinations supported by the mobile terminal 10 based on the UE Capability Information from the mobile terminal 10, the user connects the mobile terminal test device 1 and the mobile terminal 10 via a wired connection and turns on the power of the mobile terminal 10 to register the location.

[0035] When the scenario processing unit 3 receives UE Capability Information from the mobile terminal 10 during the location registration sequence, it transmits the contents of the information to the control unit 6. Note that the information is not limited to the information at the time of location registration, and the scenario processing unit 3 may request the mobile terminal 10 to transmit UE Capability Information in response to a request from the control unit 6, and transmit the received UE Capability Information to the control unit 6.

[0036] When the control unit 6 receives the UE Capability Information from the scenario processing unit 3, it checks whether the band combination set in the own device exists in the carrier aggregation band combination list of the UE capability information.

[0037] If the carrier aggregation band combination list contains the band combination set in the own device, the control unit 6 causes the display unit 5 to display that the call can be connected.

[0038] The control unit 6 displays, for example, a screen such as that shown in FIG. 2, indicating that a call can be connected with the current settings.

[0039] In FIG. 2, a PCC tab 101 is a tab for selecting the setting of a CC that is set as a PCC.

[0040] The SCC1 tab 102 is a tab for selecting the setting of the CC that is set as the first SCC.

[0041] The SCC2 tab 103 is a tab for selecting the setting of the CC that is set as the second SCC.

[0042] 2 shows a state in which PCC, SCC1, and SCC2 are set. In this embodiment, PCC and SCC1 to SCC3 can be set.

[0043] The PCC display unit 104 displays the contents of the setting parameters of the PCC, and when a corresponding part is selected by operating the operation unit 4, the control unit 6 accepts a change in the value of the corresponding parameter.

[0044] The SCC1 display unit 105 displays the contents of the setting parameters of the SCC1, and when a corresponding part is selected by operating the operation unit 4, the control unit 6 accepts a change in the value of the corresponding parameter.

[0045] The SCC2 display unit 106 displays the contents of the setting parameters of the SCC2, and when a corresponding part is selected by operating the operation unit 4, the control unit 6 accepts a change in the value of the corresponding parameter.

[0046] If the Carrier Aggregation Band Combination List contains a Band Combination set in the device itself, the control unit 6 changes the colors of the PCC tab 101, SCC1 tab 102, and SCC2 tab 103 to indicate that a call can be connected.

[0047] The user can check the current settings on the PCC display unit 104, SCC1 display unit 105, and SCC2 display unit 106, and if a call cannot be connected, the user can change the settings by operating the operation unit 4 to select the part of the PCC display unit 104, SCC1 display unit 105, or SCC2 display unit 106 that they want to change.

[0048] The call connection confirmation process performed by the mobile terminal test device 1 according to this embodiment configured as described above will be described with reference to Fig. 3. The call connection confirmation process described below is executed when the execution of call connection confirmation is selected by a user's operation on the operation unit 4.

[0049] In step S1, the control unit 6 acquires UE Capability Information from the scenario processing unit 3. After executing the process of step S1, the control unit 6 executes the process of step S2.

[0050] In step S2, the control unit 6 extracts the band combination from the UE capability information. After executing the process of step S2, the control unit 6 executes the process of step S3.

[0051] In step S3, the control unit 6 determines whether or not there is a band combination that is the same as the setting of the own device.

[0052] If it is determined that the same band combination as the setting of the own device exists, the control unit 6 executes the process of step S4. If it is determined that the same band combination as the setting of the own device does not exist, the control unit 6 executes the process of step S5.

[0053] In step S4, the control unit 6 changes the display of CCs in which the same Band Combination exists. After executing the process of step S4, the control unit 6 executes the process of step S6.

[0054] In step S5, the control unit 6 returns the display of CCs for which the same Band Combination does not exist. After executing the process of step S5, the control unit 6 executes the process of step S6.

[0055] In step S6, the control unit 6 determines whether or not the end of parameter setting has been selected and the setting has ended.

[0056] If it is determined that the setting has been completed, the control unit 6 ends the call connection confirmation process. If it is determined that the setting has not been completed, the control unit 6 executes the process of step S7.

[0057] In step S7, the control unit 6 performs a process for changing the parameters. After performing the process of step S7, the control unit 6 performs the process of step S3.

[0058] As described above, in the above embodiment, the control unit 6 checks whether the band combination set in the UE is present in the Carrier Aggregation Band Combination List of the UE Capability Information, and if the band combination set in the UE is present in the Carrier Aggregation Band Combination List, causes the display unit 5 to display that the call can be connected.

[0059] This indicates that the band combination set for the device itself is present in the Carrier Aggregation Band Combination List and that call connection is possible. This allows the user to check whether call connection is possible with the test device settings before connecting a call, improving test efficiency.

[0060] Furthermore, the control unit 6 changes the display of the PCC tab 101, SCC1 tab 102, and SCC2 tab 103 displayed corresponding to each CC to indicate that the call can be connected.

[0061] As a result, if a call can be connected, the display of the PCC tab 101, SCC1 tab 102, and SCC2 tab 103 displayed corresponding to each CC will change. This makes it possible to check whether a call can be connected by setting the test equipment before connecting the call, improving the efficiency of the test.

[0062] Furthermore, every time the parameter setting is changed, the control unit 6 checks whether the band combination set in the own device exists in the carrier aggregation band combination list, and displays whether call connection is possible.

[0063] As a result, every time the parameter settings are changed, the Carrier Aggregation Band Combination List is checked to see if the band combination set in the device itself exists, and whether call connection is possible is displayed. Therefore, every time the parameter settings are changed, it is clear whether call connection is possible, which improves the efficiency of testing.

[0064] While an embodiment of the present invention has been disclosed, it will be apparent to one skilled in the art that modifications may be made thereto without departing from the scope of the present invention, and it is intended that all such modifications and equivalents be included in the following claims.
