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

  In FIG. 1, a mobile terminal test apparatus 1 according to an 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.

  The mobile terminal test apparatus 1 includes a pseudo base station unit 10, a virtual connection unit 20, an operation unit 31, a display unit 32, a display control unit 33, a control unit 40, and a storage unit 41. ing.

  The pseudo base station unit 10 simulates a base station by transmitting and receiving radio signals to and from the mobile terminal 2. The pseudo base station unit 10 generates and transmits a radio signal by encoding, modulating, frequency converting, etc. the transmission data of the control unit 40 and the virtual connection unit 20. In addition, the pseudo base station unit 10 performs frequency conversion, demodulation, decoding, and the like on the radio signal received from the mobile terminal 2 and outputs the radio signal to the control unit 40 and the virtual connection unit 20.

Further, the pseudo base station unit 10 notifies the control unit 40 of information such as a connection state with the mobile terminal 2, an assigned packet transmission rate, and a state of the mobile terminal 2.
This information includes the packet transmission rate used by the GBR bearer determined with the mobile terminal 2 when performing a test in a GBR (Guaranteed Bit Rate) bearer service.

The GBR bearer refers to a bearer in which the network guarantees the bandwidth of the PDN, and the network notifies the MBR (Max Bit Rate) and GBR to a terminal that performs communication. A bearer that does not guarantee bandwidth is called a Non-GBR bearer.

  For example, when performing a test in the VoLTE service using the mobile terminal test apparatus 1, the pseudo base station unit 10 notifies the control unit 40 of the packet transmission rate used in VoLTE determined with the mobile terminal 2.

  The virtual connection unit 20 simulates various devices to which the mobile terminal 2 is connected via a base station. The virtual connection unit 20 includes a virtual mobile terminal unit 21, a virtual SMS (Short Message Service) server unit 22, a virtual PDN (Packet Data Network) unit 23, and a connection destination selection unit 24.

  The virtual mobile terminal unit 21 simulates a mobile terminal and performs transmission to the mobile terminal 2 and communication with the mobile terminal 2. The virtual SMS server unit 22 simulates an SMS server and transmits / receives an SMS message to / from the mobile terminal 2. The virtual PDN unit 23 simulates a packet data network and transmits / receives packet data to / from the mobile terminal 2.

  The connection destination selection unit 24 selects at least one of the virtual mobile terminal unit 21, the virtual SMS server unit 22, and the virtual PDN unit 23 according to a request from the control unit 40 and connects it to the pseudo base station unit 10.

  The operation unit 31 includes input devices such as a keyboard, a mouse, a touch panel, and the like, and outputs setting information of test conditions that have been operated and input to the display control unit 33. The display unit 32 includes an image display device such as a liquid crystal display, and displays an image for inputting test condition setting information, an image indicating a state under test, and the like.

  The display control unit 33 generates and displays an image to be displayed on the display unit 32, and controls the generation and display of the image according to an instruction from the control unit 40. Further, the display control unit 33 changes the display of the display unit 32 based on the information input to the operation unit 31 or transmits the information input to the operation unit 31 to the control unit 40.

  The control unit 40 causes the display control unit 33 to display a test condition setting screen on the display unit 32 in accordance with an instruction input to the operation unit 31 to input information necessary for performing the test. In addition, the control unit 40 causes the test to be executed based on the test conditions stored in the storage unit 41 according to the instruction input to the operation unit 31, the state of the pseudo base station unit 10, and the state of communication with the mobile terminal 2. Based on such information, the display control unit 33 causes the display unit 32 to display a state under test.

  The storage unit 41 is configured by a hard disk device or a flash memory, and stores set test conditions and the like.

  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 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.

  As described above, in the present embodiment, the storage unit 41 is configured by a RAM or a hard disk device, the virtual connection unit 20, the display control unit 33, and the control unit 40 are configured by a CPU, and the pseudo base station unit 10 is a communication unit. Consists of modules.

  In the mobile terminal test apparatus 1 having such a configuration, when a test of the mobile terminal 2 is performed, test conditions are first set by the user. When the test condition setting function is selected by the operation of the operation unit 31 by the user, the control unit 40 displays the test condition setting screen on the display unit 32 and information on the base station simulated by the pseudo base station unit 10, for example. And set the sequence you want to execute.

  For example, the control unit 40 displays a screen as shown in FIG. 2 on the display unit 32 to set test conditions for a cell that is a unit of LTE (Long Term Evolution) radio signals.

  As shown in FIG. 2, the control unit 40 includes a duplex mode, an operation band (E-UTRA Band), a downlink channel number (Channel (DL)), and an uplink channel number (Channel (UL)). ), Downlink bandwidth (DL Bandwidth), uplink bandwidth (UL Bandwidth), transmission mode (Transmission Mode), etc.

  Further, the control unit 40 determines, based on the set bandwidth and transmission mode, as a packet communication test condition (Packet), a downlink MCS (Modulation and Coding Scheme) (MCS (DL)), an uplink MCS (MCS). (UL)), the number of downlink RBs (Resource Block) (N_RB (DL)), the number of uplink RBs (N_RB (UL)), and the like.

  The control unit 40 stores the test conditions set in this way in the storage unit 41 in association with the identification information.

  In addition, when the setting of the test condition of the virtual PDN unit 23 is selected by the operation of the operation unit 31 by the user, the control unit 40 displays a screen for setting the parameters of the PDN on the display unit 32 to display the IP address. Type, the IP address of the mobile terminal 2, the IP address of the PDN-Gateway, the QCI (Quality Of Service) Class Identifier (QCI), the APN (Access Point Name), and the conditions of the virtual PDN to be connected.

  After such test conditions are set, when the mobile terminal test apparatus 1 is connected to the mobile terminal 2 by wire and the execution of the test conditions stored in the storage unit 41 is selected by the operation of the operation unit 31, In accordance with the selected test conditions, the pseudo base station unit 10 is notified of the contents of the broadcast information, the transmission information in the location registration process, and the like, and starts operating as a pseudo base station.

  When the pseudo base station unit 10 starts operation as a pseudo base station, the pseudo base station unit 10 transmits a connection state with the mobile terminal 2, a state of the mobile terminal 2, and the like to the control unit 40.

  The control unit 40 transmits the connection state with the mobile terminal 2 and the state of the mobile terminal 2 received from the pseudo base station unit 10 to the display control unit 33 and causes the display unit 32 to display them.

  When the virtual PDN unit 23 is set as the test condition, the control unit 40 requests the virtual connection unit 20 to connect the virtual PDN unit 23 and transmits the virtual PDN parameter set as the test condition.

  The virtual PDN unit 23 starts an operation as a virtual PDN according to the parameters received from the control unit 40.

  Thereafter, when the mobile terminal 2 is turned on while the mobile terminal 2 and the mobile terminal test apparatus 1 are connected, the mobile terminal 2 transmits a location registration signal and a connection request signal to the virtual PDN.

  When receiving the location registration signal, the pseudo base station unit 10 returns a signal according to the set test conditions, and for example, ends the location registration normally.

  When receiving the connection request signal to the virtual PDN, the virtual PDN unit 23 normally ends the connection request from the mobile terminal 2, for example, according to the set test conditions, so that the packet signal can be transmitted and received. At this time, when the virtual mobile terminal unit 21 and the virtual SMS server unit 22 are set as test conditions, the packet signal can be transmitted and received in the same manner.

  In such a mobile terminal test apparatus 1, when the control unit 40 is selected to measure the throughput using the virtual PDN unit 23 by the operation of the operation unit 31 by the user, as shown in FIG. A list of virtual PDNs for which parameters are set as test conditions is displayed on the display unit 32.

  Similarly, when the control unit 40 is selected to measure the throughput using the virtual mobile terminal unit 21 or the virtual SMS server unit 22 by the operation of the operation unit 31 by the user, the test conditions similar to those in FIG. A list in which parameters are set is displayed on the display unit 32.

  When at least one of the lists is selected by the operation of the operation unit 31 (in the figure, the state is in the black and white inversion state), and the start button 101 is selected by the operation of the operation unit 31, the control unit 40 Based on the transmission mode, MCS, and the number of RBs set as the above, a theoretical maximum packet transmission rate under test conditions is obtained, and dummy data is transmitted from the virtual PDN unit 23 to the mobile terminal based on the obtained theoretical maximum packet transmission rate 2 to send.

  At this time, when a plurality of virtual PDNs are selected from the list, a transmission rate obtained by equally dividing the obtained theoretical maximum packet transmission rate by the number of selected virtual PDNs is set as the transmission rate of each virtual PDN. For example, when two virtual PDNs are selected from the list, the transmission rate obtained by dividing the obtained theoretical maximum packet transmission rate into two equals is set as the transmission rate of each virtual PDN, and three virtual PDNs are selected from the list In this case, the transmission rate obtained by dividing the obtained theoretical maximum packet transmission rate into three equal parts is used as the transmission rate of each virtual PDN.

  Further, in the case where the communication with the virtual mobile terminal unit 21 (for example, the VoLTE service) is performed simultaneously and the throughput is measured, the packet transmission assigned to the communication with the virtual mobile terminal unit 21 from the obtained theoretical maximum packet transmission rate. The transmission rate obtained by subtracting the rate and equally dividing the subtracted packet transmission rate by the number of selected virtual PDNs may be used as the transmission rate of each virtual PDN.

  At this time, the packet transmission rate assigned to the communication with the virtual mobile terminal unit 21 is automatically obtained by the control unit 40 acquiring the transmission rate determined between the pseudo base station unit 10 and the mobile terminal 2 from the pseudo base station unit 10. It may be set manually, or may be set by operating the operation unit 31 by the user.

  Instead of assigning a transmission rate equal to each virtual PDN, transmission is performed at a predetermined ratio (for example, when two virtual PDNs are selected, a transmission rate is assigned at a ratio of 7: 3). You may make it allocate a rate.

  The virtual PDN unit 23 creates dummy data and transmits a packet signal to the mobile terminal 2 via the pseudo base station unit 10 based on the packet transmission rate determined by the control unit 40.

  The pseudo base station unit 10 measures the throughput from the actual transmission amount of the packet signal and transmits it to the control unit 40.

  The control unit 40 transmits the received throughput to the display control unit 33 and causes the display unit 32 to display the received throughput.

  In this way, when measuring throughput, packet signals are transmitted at the packet transmission rate determined by the theoretical maximum packet transmission rate and the set test conditions, so it is necessary to calculate the packet transmission rate that matches the test conditions. Therefore, the efficiency of the test can be improved.

  In addition, since the throughput can be measured simply by selecting the virtual PDN to which the packet signal is to be transmitted from the list of PDNs displayed on the display unit 32 and selecting the start button 101, the parameter is specified on the command line interface. Thus, it is not necessary to transmit packet signals, and the efficiency of test execution can be improved.

  In the present embodiment, the case of LTE has been shown, but it can be similarly performed by W-CDMA (Wideband-Code Division Multiple Access), GPRS (General Packet Radio Service), and the like.

  In this embodiment, packet signal transmission of one or more virtual PDNs is started simultaneously to perform packet signal transmission by a plurality of virtual PDNs, but packet transmission of one virtual PDN is sequentially started, Packet signal transmission by a plurality of virtual PDNs may be performed.

  In the present embodiment, the theoretical maximum packet transmission rate is automatically obtained. However, a method of automatically obtaining the theoretical maximum packet transmission rate and a method of manually setting the packet transmission rate may be selected.

  By doing so, it is possible to carry out a test at a packet transmission rate that is not the theoretical maximum packet transmission rate.

  In the present embodiment, the theoretical maximum packet transmission rate is obtained in the case of automatic. However, the present invention is not limited to this, and the packet transmission rate may be obtained according to preset conditions.

  A throughput measurement process performed by the mobile terminal test apparatus according to the present embodiment configured as described above will be described with reference to FIG. Note that the throughput measurement process described below is executed when the start button 101 is selected on the screen shown in FIG.

  In step S1, the control unit 40 obtains information for identifying the selected virtual PDN that is black and white reversed on the screen shown in FIG. 3 to be transmitted from the display control unit 33, and uses the identification information as the virtual PDN unit. 23.

  In step S2, the virtual PDN unit 32 obtains the address of the mobile terminal 2 to which the virtual PDN is connected from the virtual PDN information corresponding to the received identification information.

  In step S <b> 3, the control unit 40 causes the display unit 32 to display a screen for inquiring whether to set the packet transmission rate and the transmission source port automatically or manually. Determine whether auto is selected.

  If it is determined that the automatic mode is selected, in step S4, the control unit 40 obtains the theoretical maximum packet transmission rate based on the test conditions.

  At this time, when a plurality of virtual PDNs are selected from the list, a transmission rate obtained by equally dividing the obtained theoretical maximum packet transmission rate by the number of selected virtual PDNs is set as the transmission rate of each virtual PDN. For example, when two virtual PDNs are selected from the list, the transmission rate obtained by dividing the obtained theoretical maximum packet transmission rate into two equals is set as the transmission rate of each virtual PDN, and three virtual PDNs are selected from the list In this case, the transmission rate obtained by dividing the obtained theoretical maximum packet transmission rate into three equal parts is used as the transmission rate of each virtual PDN.

  Further, in the case where the communication with the virtual mobile terminal unit 21 (for example, the VoLTE service) is performed simultaneously and the throughput is measured, the packet transmission assigned to the communication with the virtual mobile terminal unit 21 from the obtained theoretical maximum packet transmission rate. The transmission rate obtained by subtracting the rate and equally dividing the subtracted packet transmission rate by the number of selected virtual PDNs is defined as the transmission rate of each virtual PDN.

  At this time, the packet transmission rate assigned to the communication with the virtual mobile terminal unit 21 is automatically obtained by the control unit 40 acquiring the transmission rate determined between the pseudo base station unit 10 and the mobile terminal 2 from the pseudo base station unit 10. It may be set manually, or may be set by operating the operation unit 31 by the user.

  Instead of assigning a transmission rate equal to each virtual PDN, transmission is performed at a predetermined ratio (for example, when two virtual PDNs are selected, a transmission rate is assigned at a ratio of 7: 3). You may make it allocate a rate.

  In step S5, the control unit 40 obtains a free port between the selected virtual PDN and the mobile terminal 2, and sets that port as the transmission source port. The control unit 40 transmits a transmission start request in which the obtained packet transmission rate and transmission source port are set to the virtual PDN unit 23.

  If it is determined in step S3 that manual is selected, in step S6, the control unit 40 displays a screen for allowing the display unit 32 to input necessary information such as a packet transmission rate, a transmission source port number, and a protocol type. To input the correct information.

  When necessary information is input, the control unit 40 transmits a transmission start request in which the input information is set to the virtual PDN unit 23.

  In step S7, when the virtual PDN unit 23 receives the transmission start request, the virtual PDN unit 23 generates dummy data according to the packet transmission rate and the transmission source port set in the transmission start request and starts transmission of the packet signal.

  In step S <b> 8, the control unit 40 transmits the throughput measured by the pseudo base station unit 10 to the display control unit 33 and causes the display unit 32 to display the throughput.

  Next, the theoretical maximum packet transmission rate calculation processing in step S4 will be described with reference to FIG.

  In step S11, the control unit 40 acquires the transmission mode (hereinafter referred to as “TM”), MCS, and the number of RBs (hereinafter referred to as “NRB”) from the test conditions of the selected virtual PDN.

  In step S12, the control unit 40 obtains TBS from a table in which TBS (Transport Block Size) is determined from TM, MCS, and NRB, for example. The TBS indicates the maximum number of bits that can be transmitted at a frame interval of 10 milliseconds.

  In step S13, the control unit 40 obtains the theoretical maximum packet transmission rate from the obtained TBS.

  Thus, in the above-described embodiment, when throughput is measured, a list of virtual PDNs for which parameters are set as test conditions is displayed on the display unit 32, and at least one of the lists is an operation of the operation unit 31. When the start button 101 is selected by operating the operation unit 31, the packet transmission rate is obtained based on the test condition, and dummy data is transmitted from the virtual PDN unit 23 to the mobile terminal 2 according to the obtained packet transmission rate. A control unit 40 is provided.

  Thereby, a packet signal is transmitted by selecting from the list of virtual PDNs displayed on the display unit 32 and selecting the start button 101. For this reason, it is not necessary to manually input parameters and the like on the command line interface, and the efficiency of test execution can be improved.
