Description

[Technical field]

[0001] The present invention relates to a measurement device having a measurement function for a communication terminal and a display control function for information related to the measurement, for simulating a base station in an operation mode in which new and old communication standards are mixed and testing the communication terminal, a communication terminal measurement system, and a measurement-related information display method. [Background technology]

[0002] For example, in mobile phone systems, as mobile terminals become more multifunctional, the speed of wireless communication between wireless base stations (hereinafter referred to as "base stations") is increasing, and in recent years, technological development has been progressing to transition from 4G (fourth generation) services, which adopt the LTE-Advanced system, to 5G (fifth generation) services.

[0003] In order to realize a new wireless communication system (NR) for 5G, non-standalone NR, which is operated by combining LTE and NR as disclosed in Non-Patent Document 1, is being considered. In addition, as disclosed in Non-Patent Document 2, non-standalone NR operation is based on the combined use of Carrier Aggregation (hereinafter referred to as CA) technology, which bundles component carriers (hereinafter referred to as CC) used before the LTE-Advanced system standard within the same base station for communication, and Dual Connectivity (hereinafter referred to as DC) technology, which simultaneously communicates between an NR base station and an LTE base station.

[0004] First, we will explain non-standalone NR operation. Non-standalone NR operation is being considered for adoption in the transition phase to standalone operation, which can be operated only with NR, and is an operational form that provides 5G wireless services by combining existing LTE / LTE-Advanced areas with NR areas.

[0005] In non-standalone NR operation, for example, as shown in Fig. 20, an EPC (Evolved Packet Core) is adopted as a core network, and LTE areas and NR areas are mixed in the core network. In the LTE area and the NR area, multiple base stations LTE1 to LTEn and NR1 to NRn may exist, respectively.

[0006] Existing LTE / LTE-Advanced systems use CA technology, which bundles CCs of the same base transceiver station (BTS), but in non-standalone NR operation, in addition to CA technology, DC technology, which bundles carriers between different BTSs within each NR and LTE area, is also used.

[0007] In the non-standalone NR network configuration, the above-mentioned DC performs data communication using radio resources of two BTSs called a master node (Master Node) and a secondary node (Secondary Node). In this case, for example, as shown in FIG. 21, the master node MNB (Master Node BTS) is a branching point of user data transmission, and downstream data transferred from the S-GW (Serving GateWay) via the S1 interface is delivered to the secondary node SNB (Secondary Node BTS) side via the carrier of the master node MNB or the X2 interface, and transmission is performed via the carrier of the secondary node SNB.

[0008] In addition, in DC in non-standalone NR operation, RRC (Radio Resource Control) for connecting to the network is established only with the master node MNB, and control of the secondary node SNB is performed via the master node MNB. This type of control includes secondary node addition for setting a carrier provided by the secondary node SNB to the user equipment (UE), which is a terminal, and secondary node deletion for deleting the carrier.

[0009] As an example, a procedure for deleting a secondary node is shown in Fig. 22. In this procedure, the user equipment UE first transmits a measurement report to the MNB, which is a base station operating as a master node, to connect to the MNB, and then executes a DC setting procedure when the user equipment UE informs the MNB that the quality of a cell under the SNB, which is a base station set as a secondary node, is good.

[0010] In the DC setting procedure, the base station MNB transmits a DC setting request (SN Addition Request) to the SNB (step S01). The SNB stores radio parameter information of the subordinate cell in a response signal (SN Addition Request Acknowledgement) to the DC setting request and transmits it to the SNB (step S02). When the MNB subsequently receives the response signal from the SNB, it transmits a radio resource setting signal (RRC connection reconfiguration) to the user equipment UE (step S03). The user equipment UE transmits a completion notification (RRC connection reconfiguration complete) corresponding to the setting signal to the MNB (step S04), starts a synchronization establishment procedure to the SNB, and becomes a connection state established state with the SNB by the completion of the procedure.

[0011] When the MNB receives the completion notification from the user device UE, the MNB transfers a completion notification (SN reconfiguration complete) to the SNB (step S05) and completes the DC setting procedure. After this, the base station MNB executes a process of distributing downlink user data sent from the S-GW to the base station SNB.

[0012] In addition, in DC in non-standalone NR operation, a protocol stack as shown in Fig. 23 is adopted. In the existing LTE, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, a medium access control (MAC) layer, and a physical layer are set between the base station and the UE from the top, whereas in DC, as shown in Fig. 23, in order for multiple base stations to communicate with the user equipment UE, the protocol stack is separated below the PDCP layer in the MNB on the base station side, and the same protocol stack as in the past is prepared for the MNB and SNB below the RLC layer. On the other hand, a corresponding protocol layer is prepared on the user equipment UE side.

[0013] In addition, DC differs from CA in the functionality of PCell (Primary Cell) and SCell (Secondary Cell) used to transmit control signals. In CA, only a part of the PCell functionality is supported in SCell. Specifically, SCell does not support PUCCH (Physical Uplink Control CHannel) or CBRA (Contention Based Random Access), and transmission of UCI (Uplink Control Information) such as HARQ (Hybrid Automatic Retransmission) response signals and DL (Downlink) quality information, as well as uplink scheduling requests to the base station, is basically performed in PCell.

[0014] In contrast, in DC, there is a large delay between the base stations MNB / SNB that bundle the carriers, making it difficult to notify the UCI and scheduling requests received on the MNB's PCell to the SNB in ​​real time via the backhaul and reflect them in the scheduling of the subordinate SCells.

[0015] Therefore, in DC, for example, as shown in Fig. 24, in addition to the PCell, one carrier under the SNB is set as a PSCell (Primary SCell) to support PUCCH transmission, CBRA, etc., and UCI and scheduling requests related to each carrier under the SNB can be transmitted directly from the user equipment UE to the SNB. This makes it possible to realize communication with multiple base stations without being affected by delays between the MNB / SNB. In addition, the PSCell also has functions that were previously only supported by the PCell, such as a downlink radio quality monitoring function, so that the user equipment UE can stably transmit and receive with the SNB.

[0016] In non-standalone NR operation equipped with the DC technology described with reference to Figures 20 to 24, in addition to the "high speed and large capacity" of LTE / LTE-Advanced, it is also possible to achieve the benefits of "low latency and high reliability."

[0017] For this reason, in a measurement device that measures a terminal that communicates according to the NR standard through non-standalone NR operation, a display control function is desired that displays cell (base station) images to identify base stations in both NR and LTE areas that are set up to perform simulated communication with the terminal, and carrier images to identify carrier usage status.

[0018] Regarding a device that tests the communication operation of a mobile communication terminal by simulating a base station that transmits and receives signals based on various communication standards including LTE, Patent Document 1 proposes a technology that displays information that includes information indicating the subordinate relationships of multiplex communication, so that the user can understand the settings of the multiplex communication and the state of the multiplex communication during the test.

[0019] For example, the display control unit 5 described in Patent Document 1 controls the display unit 6 to perform a desired display, for example in the display format shown in Figure 25, based on a control signal from the pseudo base station control unit 4 based on setting information.

[0020] The display section 6 is composed of a display device such as a liquid crystal panel, and has a sequence display section 6a, a connection state display section 6b, a connection destination display section 6c, and in addition a multiplex communication related display section 6d.

[0021] The sequence display unit 6a displays a number of sequences indicating the communication procedures and communication transition states between a terminal 11 (e.g., a mobile communication terminal such as a G4 terminal) and a virtual destination 12 for packet data communication for each service between the terminal 11 and the virtual destination 12 via the measurement device 1.

[0022] Specifically, as shown in FIG. 25, the sequence display unit 6a displays, as a plurality of sequences, a “Power Off” sequence indicating a power off state of the terminal 11, a “Detach” sequence indicating a location registration deleting state of the terminal 11, a “Registration” sequence indicating a location registration state of the terminal 11, an “Idle” sequence indicating a standby state of the terminal 11, an “Origination” sequence indicating an outgoing call state of the terminal 11, a “Termination” sequence indicating an incoming call state of the terminal 11, a “Communication” sequence indicating a communication state of the terminal 11, a “UE (user equipment) Release” sequence indicating a disconnection state from the terminal 11, and a “NW (network) Release” sequence indicating a disconnection state from the virtual destination 12.

[0023] These sequences are displayed in a flow chart format with arrows indicating the transition direction of each communication procedure and communication state between the sequences under the control of the display control unit 5. At that time, the display state changes according to the transition state. That is, when the corresponding sequence reaches a transition state, the corresponding sequence is displayed in a display state different from the previous display state, for example, by changing the display color or the display brightness.

[0024] In FIG. 25, the arrows between the sequences in the sequence display section 6a indicate the transition directions of the communication procedures and communication states.

[0025] The connection status display section 6b displays the connection status between the terminal 11 and the virtual destination 12 (virtual destination 12a, virtual server 12b, virtual TV phone 12c) via the measurement device 1.

[0026] To explain further, under the control of the display control unit 5, the connection status display unit 6b displays the terminal 11, the pseudo base station control unit 4, and the virtual connection destination 12 (virtual destination 12a, virtual server 12b, virtual TV phone 12c) as graphical icons, and changes the display state depending on the presence or absence of connection, displaying graphically a plurality of connection lines between the terminal 11 and the virtual connection destination 12 (virtual destination 12a, virtual server 12b, virtual TV phone 12c) to the pseudo base station control unit 4. That is, depending on the presence or absence of connection, the display color of the relevant connection line is changed, or the display brightness is changed.

[0027] The destination display section 6c graphically displays one virtual destination 12 (virtual destination 12a, virtual server 12b, or virtual TV phone 12c) to which the terminal 11 is connected via the pseudo base station control section 4.

[0028] When the terminal 11 performs multiple communication, the multiple communication related display unit 6d displays, under the control of the display control unit 5 via the pseudo base station control unit 4, the multiple communication related information determined by the display information determination unit 13 to allow the user to grasp the settings of the multiple communication and the state of the multiple communication under test, the aforementioned Priority, Status, PDN / PDP-Type, IP-version, QCI, EBI / NSAPI, Linked-EBI / Linked-NSAPI, UE-Address, DNS-Address, and Access-Point-Name in a list format, for example, as shown in FIG. 25.

[0029] Conventionally, the simulation model setting screen 33b has been displayed in a screen configuration as shown in Fig. 26. A conventional simulation model parameter setting screen 331 shown in Fig. 26 has a simulation model area 331a and a simulation model display area 331b.

[0030] In the simulation model area 331a, tools for selecting communication methods (MIMO, etc.), DL and UL conditions (Modulation Support), and various wireless communication standards are arranged horizontally, and a BTS selection column is arranged vertically, and the above items are set for each BTS using radio buttons, etc. In the case of such a table format, it becomes necessary to expand the display area horizontally and vertically as the number of BTSs increases.

[0031] However, the conventional device described in Patent Document 1 had a function to display, for example, the operational status of base stations within an LTE area regarding measurements by 4G terminals, and was not configured to display various information regarding the operation of base stations in both NR and LTE areas through non-standalone NR operation.

[0032] In particular, in conventional devices, base stations in an LTE area set for performing simulated communication with a 4G terminal are generally displayed by arranging cell icons corresponding to each base station as shown in Fig. 26. In addition, when considering displaying cell icons corresponding to each base station in the connection status display unit 6b in Fig. 25, there was a concern that in the future, in order to display all base stations in non-standalone NR operation in which the number of base stations is expected to increase in both NR and LTE areas, there would be a shortage of display space, the screen would be difficult to see, and usability would decrease.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0053] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a measurement device, a communication terminal measurement system, and a measurement-related information display method according to the present invention will be described with reference to the drawings.

[0054] The measuring device and communication terminal measurement system of the present invention simulates a base station by transmitting and receiving signals (RF signals) based on a specified communication standard (e.g., LTE or NR) between a mobile communication terminal such as a newly developed mobile phone and tests the communication operation of the mobile communication terminal.

[0055] In particular, the measurement device and communication terminal measurement system according to the present invention are also capable of measuring terminals that communicate in accordance with the above-mentioned NR communication standard, and have a function of simulating NR base stations and LTE base stations located in the NR and LTE areas of a non-standalone NR network. The NR communication standard and the LTE communication standard correspond to the first communication standard and the second communication standard of the present invention, respectively.

[0056] The measurement device and communication terminal measurement system of the present invention have a display function for understanding the settings of multiplex communication and the status of multiplex communication during testing, including information indicating the subordinate relationships of multiplex communication, as well as a measurement function for user equipment UE (terminal) used for non-standalone NR operation and a display function for measurement-related information related to that measurement.

[0057] 1, a measurement device 1A according to an embodiment of the present invention is generally configured to include, as components for realizing the above measurement function and display function, an operation unit 2, a transmission / reception unit 3, a pseudo base station control unit 4, a display control unit 5, and a display unit 6. Each component will be described below.

[0058] The operation unit 2 is composed of an operation panel such as switches and buttons provided on the front of the housing of the measurement device 1A, for example. The operation unit 2 selectively performs various settings required for the communication operation test of the mobile communication terminal (hereinafter abbreviated as terminal) 11a to be tested, including instructions to start and stop the communication operation test of the terminal 11a, and settings of various information required for desired display on the display unit 6 (sequence display unit 6a, connection status display unit 6b, connection destination display unit 6c, and multiplex communication related display unit 6d, which will be described later). The terminal 11a described in this embodiment is a 5G terminal, and is compatible with 5GNR, LTE, and communication standards before LTE.

[0059] Under the control of the pseudo base station control unit 4, the transceiver unit 3 transmits a signal (RF signal) conforming to the NR communication standard, the LTE communication standard, or a communication standard prior to LTE from the virtual destination 12 to the terminal 11a under test, and inputs a signal (RF signal) conforming to the NR communication standard, the LTE communication standard, or a communication standard prior to LTE received from the terminal 11a to the virtual destination 12. The transceiver unit 3 has a function capable of appropriately transmitting and receiving signals conforming to the NR communication standard, the LTE communication standard, or a communication standard prior to LTE between the pseudo base station and terminal 11a.

[0060] The virtual connection destination 12 is incorporated inside the measurement device 1A and is a destination that can be connected to the terminal 11a under the control of the pseudo base station control unit 4, and as shown in Figure 1, it consists of, for example, a virtual call destination 12a, a virtual server 12b, a virtual TV phone 12c, a virtual NR network 12d, etc.

[0061] The pseudo base station control unit 4 performs overall control of the transmitting / receiving unit 3, the display control unit 5, and the display unit 6 based on operation information from the operation unit 2 in order to execute a predetermined scenario and perform a communication operation test of the terminal 11a.

[0062] The scenario describes a test procedure of a series of operations for simulating a communication sequence based on a predetermined communication standard (e.g., LTE standard, NR standard, etc.) in the measurement device 1A simulating a base station. In the measurement device 1A according to the present embodiment, the above scenario also describes a test procedure of a series of operations for simulating a communication sequence based on the NR communication standard between each base station in the LTE area and the NR area in a network related to non-standalone NR operation and the terminal 11a, which is a terminal to be measured. That is, the virtual NR network 12d, which is one of the virtual destinations 12, has a functional configuration for simulating communication based on the NR communication standard with this terminal 11a.

[0063] In addition, the pseudo base station control unit 4 has a display information determination unit 13 that determines various display information to be displayed on the multiplex communication related display unit 6d (described later) based on operation information (including setting information) from the operation unit 2 and notification information from the terminal 11a when the terminal 11a performs multiplex communication.

[0064] To explain further, as shown in FIG. 1, the display information determination unit 13 includes a Priority determination unit 13a, a Status determination unit 13b, a PDN / PDP-Type determination unit 13c, an IP (Internet Protocol)-version determination unit 13d, a QCI determination unit 13e, an EBI (EPS Bearer Identifier) / NSAPI (Network Service Access Point Identifier) ​​determination unit 13f, a Linked-EBI / Linked-NSAPI determination unit 13g, a UE-Address determination unit 13h, a DNS (Domain Name System)-Address determination unit 13i, an Access-Point-Name determination unit 13j, and an NR measurement related information determination unit 13k.

[0065] The priority determination unit 13a, the status determination unit 13b, the PDN / PDP-Type determination unit 13c, the IP (Internet Protocol)-version determination unit 13d, the QCI determination unit 13e, the EBI (EPS Bearer Identifier) / NSAPI (Network Service Access Point Identifier) ​​determination unit 13f, the Linked-EBI / Linked-NSAPI determination unit 13g, the UE-Address determination unit 13h, the DNS (Domain Name System)-Address determination unit 13i, and the Access-Point-Name determination unit 13j are shared by the system before LTE, LTE, and NR. The NR measurement related information determination unit 13k processes information only for NR.

[0066] The priority determination unit 13a determines a priority, which is a number for distinguishing a PDN (Packet Data Network) or a PDP (Packet Data Protocol), within the measurement device 1A. When the terminal 11a makes a call, the measurement device 1A automatically adds this priority upon receiving the call from the terminal 11a. When the measurement device 1A makes a call, the tester operates the operation unit 2 to set the priority in advance.

[0067] Note that PDN and PDP are logical connections based on packet data communication for each service between a terminal (hereinafter also referred to as UE) 11 and a virtual destination 12 via a packet data communication network, and are called PDN in LTE and PDP in GSM (registered trademark) / W-CDMA.

[0068] In addition, multi-PDP (multi-PDN) means that there are multiple PDPs (PDNs), in other words, multiple connections. There are two main types, (a) and (b), as shown below, and they may also be mixed.

[0069] (a) PDPs for completely different services are multiplexed. In this case, each communication destination will have a different IP address, and the UE will have multiple connections to communication destinations with different IP addresses. The PDP-Type for each will be Primary (default in LTE). In addition to communication destinations, there are also cases where a single UE will carry out multiple communications with multiple IP addresses. This case also results in multi-PDP.

[0070] (b) PDPs for mutually related services are multiplexed. For example, when communicating voice data using VoIP (Voice over Internet Protocol), the UE exchanges control information (login, incoming call notification, etc.) with a SIP (Session Intiation Protocol) server, and also exchanges voice data. In this case, the control information and the voice data are in separate PDPs, resulting in a multi-PDP. Here, the PDP-Type for each is Primary (Default in LTE) for control information and Secondary (Dedicated in LTE) for voice data.

[0071] VoIP is a technology that compresses voice using various encoding methods, converts it into packets, and transmits it in real time over an IP network. LTE is a packet-switched communication method, so calls are made via VoIP.

[0072] SIP is a session control protocol for starting, changing, terminating, and other operations in two-way real-time communications such as telephone and videophone. The SIP server used in VoIP mediates communications between UEs.

[0073] The status determination unit 13b determines a status that indicates a connection state. In the multiplex communication related display unit 6c described later, under the control of the display control unit 5 based on the status determined by the status determination unit 13b, two states, a connected state (a state in which a PDN or a PDP is registered) and a disconnected state (a state in which a PDN or a PDP is not registered), are displayed with respective corresponding icons to distinguish them from one another, as shown in Fig. 25. The measurement device 1A judges the state and automatically switches the display.

[0074] Here, a connected state is a state in which an IP address has been assigned, and a disconnected state is a state in which an IP address has not been assigned. It is not a disconnected state simply because there is no communication. In actual operation, even if wireless communication is momentarily cut off when entering a tunnel during communication, PDP registration is maintained, and communication is resumed when wireless communication is restored. A disconnected state can occur due to spontaneous disconnection processing or a long timeout.

[0075] The PDN / PDP-type determination unit 13c determines a PDN-type that indicates the type of the PDN and a PDP-type that indicates the type of the PDP.

[0076] There are two types of PDN-Type: Default and Dedicated, and there are two types of PDP-Type: Primary and Secondary.

[0077] Taking PDP-Type as an example, Primary is a PDP that has an IP address and is a parent PDP. There can be multiple Primary PDPs.

[0078] Secondary is a PDP that does not have an IP address, and is a child PDP, so to speak. A Primary PDP can exist independently, whereas a Secondary PDP is subordinate to the Primary PDP. Multiple Secondary PDPs can be subordinate to one Primary PDP. In terms of PDN-Type, Default corresponds to Primary, and Dedicated corresponds to Secondary.

[0079] The PDN / PDP-Type determination unit 13c determines the values ​​of the PDN-Type and PDP-Type in different ways depending on whether the communication standard is LTE or GSM / W-CDMA.

[0080] That is, when the communication standard is LTE and terminal 11a originates a call, terminal 11a determines and notifies the PDN type, and PDN / PDP-type determination unit 13c outputs the information to display control unit 5. When the communication standard is LTE and measurement device 1A originates a call, PDN / PDP-type determination unit 13c allows the tester to set the PDN type in advance by operating operation unit 2. Note that the PDN type can also be automatically set by measurement device 1A.

[0081] When the communication standard is GSM / W-CDMA and the terminal 11a originates a call, the terminal 11a determines and notifies the PDP-Type, and the PDN / PDP-Type determination unit 13c outputs the information to the display control unit 5. When the communication standard is GSM / W-CDMA and the measurement device 1A originates a call, the terminal 11a notifies the PDP-Type and NSAPI in response to the notification of the Access-Point-Name from the measurement device 1A, and the PDN / PDP-Type determination unit 13c makes a decision based on the information.

[0082] Then, in the multiplex communication related display section 6d described later, either Default (Primary) or Dedicated (Secondary) is displayed in a display form shown in FIG. 25, for example, under the control of the display control section 5 based on the PDN-Type and PDP-Type determined by the PDN / PDP-Type determination section 13c.

[0083] The IP-version determination unit 13d determines the IP-version that indicates the type of IP. More specifically, when the terminal 11a makes a call, the terminal 11a determines and notifies the IP-version, and the IP-version determination unit 13d outputs the information to the display control unit 5. On the other hand, when the measurement device 1A makes a call, the tester operates the operation unit 2 to set the IP-version in advance. It is also possible for the measurement device 1A to automatically set the IP-version.

[0084] Then, in a multiplex communication related display section 6d described later, either IPv4, IPv6 or IPv4v6 is displayed in a display form shown in FIG. 13, for example, under the control of the display control section 5 based on the IP-version determined by the IP-version determination section 13d.

[0085] Note that IPv4v6 stands for dual stack, which is a technology that allows IPv4 and IPv6 to coexist and be used together, and one measuring device 1A can have both IPv4 and IPv6 addresses and use both protocols together.

[0086] The QCI determination unit 13e determines a QCI, which is an identification code indicating a class of service associated with the service content. This QCI is determined by the pseudo base station control unit 4 of the measurement device 1A. Therefore, whether the terminal 11a or the measurement device 1A is to transmit, the tester operates the operation unit 2 to set the QCI in advance. It is also possible for the measurement device 1A to automatically set the QCI.

[0087] The EBI / NSAPI determination unit 13f determines an EBI, which is basic information for identifying a PDN, and an NSAPI, which is basic information for identifying a PDP, by using IDs assigned to the PDN and PDP. EBI / NSAPI is called EBI in LTE and NSAPI in GSM / W-CDMA.

[0088] The EBI / NSAPI determination unit 13f determines the value in a different manner depending on whether the communication standard is LTE or GSM / W-CDMA.

[0089] That is, when the communication standard is LTE and the terminal 11a makes a call, the terminal 11a determines and notifies the EBI, and the EBI / NSAPI determiner 13f outputs the information to the display control unit 5. As an example, when the communication standard is LTE and the terminal 11a notifies the EBI "5" for PDN1 (Default) and the EBI "6" for PDN2 (Dedicated), the EBI / NSAPI determiner 13f outputs this information to the display control unit 5. Also, when the communication standard is LTE and the measurement device 1A makes a call, the tester operates the operation unit 2 to set the EBI in advance, and the EBI / NSAPI determiner 13f sets the EBI in advance. It is also possible for the measurement device 1A to automatically set the EBI.

[0090] On the other hand, when the communication standard is GSM / W-CDMA and the terminal 11a makes a call, the terminal 11a determines and notifies the NSAPI, and the EBI / NSAPI determination unit 13f outputs the information to the display control unit 5. As an example, in the communication standard GSM / W-CDMA, when the terminal 11a notifies the NSAPI "5" of PDN1 (Primary) and the NSAPI "6" of PDN2 (Secondary), the EBI / NSAPI determination unit 13f outputs the information to the display control unit 5. Also, when the communication standard is GSM / W-CDMA and the measurement device 1A makes a call, the tester operates the operation unit 2 to set the NSAPI in advance. It is also possible for the measurement device 1A to automatically set the NSAPI.

[0091] The Linked-EBI / Linked-NSAPI determination unit 13g determines the Linked-EBI / Linked-NSAPI based on the setting information by the operation of the operation unit 2 and the information (notification information) included in the packet for each service from the terminal 11a. The Linked-EBI / Linked-NSAPI is assigned only to the Secondary PDP (Dedicated PDN) and is dependency identification information that indicates which Primary PDP (Default PDN) the terminal belongs to.

[0092] The Linked-EBI / Linked-NSAPI determination unit 13g determines the values ​​of Linked-EBI / Linked-NSAPI in different ways depending on whether the communication standard is LTE or GSM / W-CDMA.

[0093] To explain further, when the communication standard is LTE and the terminal 11a is transmitting, the terminal 11a determines and notifies the Linked-EBI, and the Linked-EBI / Linked-NSAPI decision unit 13g outputs the information to the display control unit 5. As an example, when the communication standard is LTE and the terminal 11a notifies the Linked-EBI "5" of PDN2 (Dedicated), the Linked-EBI / Linked-NSAPI decision unit 13g outputs this Linked-EBI "5" to the display control unit 5. Also, when the communication standard is LTE and the measurement device 1A is transmitting, the tester operates the operation unit 2 to set the Linked-EBI in advance. It is also possible for the measurement device 1A to automatically set the Linked-EBI.

[0094] In contrast, when the communication standard is GSM / W-CDMA and terminal 11a makes a call, a notification for setting up a primary PDP is sent first, which includes the values ​​of NSAPI and TI (Transaction Identifier: an identifier for identifying a process (process group)). Next, a notification for setting up a secondary PDP is sent, which includes the value of Linked-TI. Here, when the TI value of primary PDP1 and the Linked-TI value of secondary PDP2 are the same, the two are in a parent-child relationship. Using this, Linked-EBI / Linked-NSAPI determination unit 13g determines which primary PDP the secondary PDP notified from terminal 11a is subordinate to, and determines the NSAPI value of the subordinate primary PDP as the Linked-TI value of the subordinate secondary PDP. As an example, in the communication standard GSM / W-CDMA, the TI value of the Primary PDP1 and the Linked-TI value of the Secondary PDP2 are both the same value "0", so it is determined that the Primary PDP1 and the Secondary PDP2 are in a parent-child relationship, and the NSAPI value "5" of the subordinate Primary PDP1 is determined to be the Linked-NSAPI value "5" of the subordinate Secondary PDP2.

[0095] Furthermore, when the communication standard is GSM / W-CDMA and the measurement device 1A is to transmit, the tester sets the Linked-NSAPI in advance by operating the operation unit 2. It is also possible for the measurement device 1A to automatically set the Linked-NSAPI.

[0096] In this example, in the communication standard GSM / W-CDMA, the one corresponding to the Linked-EBI of the communication standard LTE is called Linked-NSAPI.

[0097] Then, in the multiple communication related display unit 6d described later, the values ​​of the dependent EBI and NSAPI are displayed in a display form shown in Figure 13, for example, under the control of the display control unit 5 using the Linked-EBI and Linked-NSAPI determined by the Linked-EBI / Linked-NSAPI determination unit 13g.

[0098] The UE-Address determination unit 13h determines the UE-Address, which is the IP address of the terminal 11a to be tested. The IP address of this terminal 11a is determined by the pseudo base station control unit 4 of the measurement device 1A. Therefore, whether the terminal 11a or the measurement device 1A is to transmit, the tester operates the operation unit 2 to set the IP address in advance. It is also possible for the measurement device 1A to automatically set the IP address of the terminal 11a.

[0099] The DNS-Address determination unit 13i determines a DNS-Address, which is the address of a DNS server. This DNS-Address is set in advance by a tester operating the operation unit 2. The DNS-Address can also be automatically set by the measurement device 1A.

[0100] A DNS server is a server that manages the correspondence between domain names and IP addresses. The measuring device 1A has an internal pseudo-network function and also simulates a DNS server. The Primary / Secondary of DNS-Address means the main system and the secondary system (DNS servers are usually prepared in two or more systems).

[0101] In the multiplex communication related display section 6d described later, the address of the DNS server is displayed in the display form shown in FIG. 25, for example, under the control of the display control section 5 according to the DNS address determined by the DNS address determination section 13i.

[0102] The Access-Point-Name determination unit 13j determines the Access-Point-Name, which is the domain name of the telecommunications carrier. A terminal 11a that performs communication under a contract with a specific telecommunications carrier, such as a mobile phone, performs communication via the Access-Point of the telecommunications carrier. The measurement device 1A has a pseudo-network function inside and also simulates the domain of the telecommunications carrier.

[0103] When the terminal 11a makes a call, the terminal 11a determines and notifies an Access-Point-Name, and the Access-Point-Name determination unit 13j outputs the information to the display control unit 5. When the measurement device 1A makes a call, the tester operates the operation unit 2 to set the Access-Point-Name in advance, and the Access-Point-Name determination unit 13j outputs the information to the display control unit 5. When the measurement device 1A makes a call, the tester operates the operation unit 2 to set the Access-Point-Name in advance.

[0104] It is also possible for the measurement device 1A to automatically set the Access-Point-Name. In practice, the tester, who is the terminal developer, knows what Access-Point-Name the terminal 11a will notify, and sets that Access-Point-Name in the measurement device 1A.

[0105] When the terminal 11a is measuring, the NR measurement related information determination unit 13k monitors the simulated communication operation in which the virtual NR network 12d simulates base stations in the NR area and the LTE area between the terminal 11a and the virtual NR network 12d under the control of the pseudo base station control unit 4, and outputs various information transmitted and received between the terminal 11a and the terminal 11a during the simulated communication operation to the display control unit 5 as NR measurement related information.

[0106] This time, an example is shown in which it is assumed that communication standards before LTE, such as GSM / W-CDMA, LTE, and NR are multiplexed as the configuration of the pseudo base station control unit 4. It is also possible to select and configure functions compatible only with LTE and NR.

[0107] Furthermore, in this embodiment, the display unit 6 has an NR measurement related display unit 6e having a screen configuration different from the screen configuration shown in FIG. 25. The NR measurement related display unit 6e is a functional unit that displays NR measurement related information input from the NR measurement related information determination unit 13k, and displays a main screen 33a (see FIG. 8) related to the measurement of the terminal 11a, which will be described later, and various screens in its lower hierarchy, that is, a simulation setting screen 33b (see FIG. 9, FIG. 10, FIG. 11), a connection confirmation / support screen (see FIG. 12), a DC operation confirmation screen (see FIG. 13, FIG. 14), a test case view screen (see FIG. 15), a component confirmation screen (see FIG. 16, FIG. 17), a power characteristic confirmation screen 33j (see FIG. 18), and a throughput confirmation screen 33k (see FIG. 19). In this embodiment, the display control unit 5 is also responsible for display control of the NR measurement related information for the NR measurement related information determination unit 13k.

[0108] Next, the display processing operation of the multiplex communication related information in the measurement device 1A configured as above will be described with reference to the flowcharts of Figures 2 and 3. First, the display processing procedure when the measurement device 1A transmits a signal will be described with reference to the flowchart of Figure 2.

[0109] When the measurement device 1A transmits a packet from the transmission / reception unit 3 to the terminal 11a under the control of the pseudo base station control unit 4 (ST11), the display control unit 5 acquires information that is preset in the measurement device 1A by the operation input of the operation unit 2 from among the information to be displayed on the display unit 6, via the pseudo base station control unit 4 (ST12). Next, the measurement device 1A receives a packet transmitted in response from the terminal 11a at the transmission / reception unit 3 (ST13). After that, the display control unit 5 acquires information contained in the packet from the terminal 11a from among the information to be displayed on the display unit 6, via the pseudo base station control unit 4 (ST14). Next, the measurement device 1A acquires information determined by the display information determination unit 13 based on the information contained in the packet from the terminal 11a from among the information to be displayed on the display unit 6, via the pseudo base station control unit 4 (ST15). Then, the display unit 6 displays the information acquired by the display control unit 5 in, for example, the display form shown in FIG. 25 (ST16).

[0110] Next, the display processing procedure when the terminal 11a makes a call will be described with reference to the flowchart of FIG.

[0111] When the measurement device 1A receives a packet transmitted by the terminal 11a at the transmission / reception unit 3 under the control of the pseudo base station control unit 4 (ST21), the display control unit 5 acquires information contained in the packet from the terminal 11a from among the information to be displayed on the display unit 6 through the pseudo base station control unit 4 (ST22). Next, the display control unit 5 acquires information that is preset in the measurement device 1A from among the information to be displayed on the display unit 6 through the pseudo base station control unit 4 (ST23). Next, the display control unit 5 acquires information determined by the display information determination unit 13 based on the information contained in the packet from the terminal 11a from among the information to be displayed on the display unit 6 through the pseudo base station control unit 4 (ST24). Then, the display unit 6 displays the information acquired by the display control unit 5 in, for example, the display form shown in FIG. 25 (ST25).

[0112] Next, a description will be given of the measurement operation of the terminal 11a in the measurement device 1A according to this embodiment and a display process procedure for NR measurement related information related to the measurement. First, the measurement operation of the terminal 11a will be described.

[0113] FIG. 4 is a diagram showing a connection configuration as a communication terminal measurement system 1B having the same function as the measurement device 1A according to the present embodiment. In particular, an example of a configuration is shown in which an NR measurement device 20 simulating a communication function of a base station in an NR area of ​​a non-standalone NR network, an LTE measurement device 21 configured separately from the NR measurement device 20 simulating a communication function of a base station in an LTE area of ​​a non-standalone NR network, and a control device 22 that comprehensively controls the NR measurement device 20 and the LTE measurement device 21 are connected by a network 24. The NR measurement device 20 includes a first transceiver unit (e.g., equivalent to the transceiver unit 3 that transmits and receives signals of the NR communication standard in FIG. 1) that transmits and receives signals between the NR base station and the terminal 11a, and the LTE measurement device 21 includes a second transceiver unit (e.g., equivalent to the transceiver unit 3 that transmits and receives signals of the LTE communication standard in FIG. 1) that transmits and receives signals between the LTE base station and the terminal 11a. In the communication terminal measurement system 1B of the present embodiment having such a connection mode, the control device 22 is also connected to an application server 23, which is an external server, via the network 24.

[0114] The NR measurement device 20 and the LTE measurement device 21 are connected to a measurement mechanism unit 25 including a holding mechanism for holding the terminal 11a (see "UE" in FIG. 4) to be measured. The measurement mechanism unit 25 has a configuration in which, for example, the terminal 11a to be measured and a measurement antenna (transmitting antenna and receiving antenna) capable of communicating with an antenna (not shown) built into the terminal 11a by a predetermined radio frequency signal are housed in an OTA (Over The Air) chamber 25a. In the mmW frequency range, the NR measurement device 20 is connected to an antenna in the OTA chamber 25a, and the LTE measurement device 21 is connected by wire to the terminal 11a installed in the OTA chamber 25a. Although not shown, in the Sub6GHz frequency range, the NR measurement device 20 and the LTE measurement device 21 are connected by wire to the terminal 11a via an RF Switching Box or the like.

[0115] The control device 22 functions as a control PC that centrally controls the NR measurement device 20 and the LTE measurement device 21 using a computer device such as a personal computer (PC). The control device 22 has a control unit 31, an operation unit 32, and a display unit 33, as shown in FIG. 5. The control unit 31 has a CPU 31a, a storage unit 31b, and an external interface (I / F) unit 35. The CPU 31a executes a program stored in the storage unit 31b, for example, to realize a setting control unit 30a, a simulated communication control unit 30b, a measurement control unit 30c, and a display control unit 30, which will be described later. The operation unit 32 and the display unit 33 have the same configuration as the operation unit 2 and the display unit 6 described above. The external interface (I / F) unit 31c performs an interface function for connecting the control device 22 to the NR measurement device 20 and the LTE measurement device 21 via the network 24.

[0116] In the control device 22, a CPU 31a has a setting processing unit 30a, a simulated communication control unit 30b, a measurement control unit 30c, a display control unit 30d, and a virtual connection destination 30e.

[0117] The setting processing unit 30a performs various setting processes such as setting a scenario (including a base station to be a target of simulated communication) for the measurement of the terminal 11a and setting simulation parameters, etc. The simulated communication control unit 30b executes a simulated communication operation that simulates communication between the terminal 11a to be measured and an NR base station and an LTE base station, the combination of which is set in advance for performing simulated communication, according to the above-mentioned scenario, according to the simulation parameters.

[0118] The measurement control unit 30c acquires signals transmitted and received between the NR base station and the LTE base station and the terminal 11a during simulated communication operation, and performs control so that the measurement unit measures whether the terminal 11a is operating normally.

[0119] The display control unit 30d performs display control to display on the display unit 33 measurement-related information (information for understanding the combination of base stations performing simulated communication, the carrier used, etc.) regarding the measurement of the terminal 11a based on signals transmitted and received between the terminal 11a and the NR base station and the LTE base station during simulated communication operation, in association with the type of radio access method (RAT).

[0120] The setting control unit 30a, the simulated communication control unit 30b, and the measurement control unit 30c of the control device 22 correspond to the pseudo base station control unit 4 in Fig. 1. The display control unit 30d of the control device 22 corresponds to the display control unit 5 and the NR measurement related display unit 6e shown in Fig. 1. The virtual destination 30e of the control device 22 corresponds to the virtual destination 12 in Fig. 1.

[0121] In addition, in the connection configuration shown in Fig. 4, the control device 22, the NR measurement device 20, and the LTE measurement device 21 respectively constitute the pseudo base station control unit, the first measurement device, and the second measurement device of the present invention. In addition, in the block diagram shown in Fig. 5, the display control unit 30d constitutes the display control means of the present invention.

[0122] Next, a display process procedure of NR measurement related information related to the measurement of the terminal 11a of the measurement device 1A according to this embodiment will be described with reference to the flowcharts shown in Fig. 6 and Fig. 7. First, a display process procedure before the start of measurement of the terminal 11a will be described with reference to the flowchart shown in Fig. 6.

[0123] In the measurement device 1A according to this embodiment, it is necessary to set the number of RAT cells and simulation parameters prior to measurement of the terminal 11a. In the measurement device 1A having the connection configuration shown in Fig. 4, when a measurement request for the terminal 11a is input from the operation unit 32, the control device 22 causes the display control unit 30d to display, for example, a main screen 33a relating to NR and LTE measurement shown in Fig. 8 on the display unit 33 (step S31).

[0124] While the main screen 33a is displayed, the display control unit 30d determines whether or not a RAT cell number setting request has been input (step S32). If it is determined that a RAT cell number setting request has not been input (NO in step S32), the process proceeds to step S37.

[0125] On the other hand, if it is determined that a RAT cell number setting request has been input (YES in step S32), then the display control unit 30d causes the display unit 33 to display a simulation model setting screen 33b, which is a lower hierarchical level of the main screen 33a (step S33). The simulation model setting screen 33b has, for example, a simulation model setting area (RAT cell number setting screen) 33b1 (see FIG. 10) and a simulation model display area 33b2 (see FIG. 11), as shown in FIG. 9.

[0126] While the simulation model setting screen 33b is displayed, the setting control unit 30a executes a process of setting the number of RAT cells and a process of confirming the setting of the simulation model based on an input from the operation unit 33 (step S34).

[0127] While executing the setting process in step S34, the display control unit 30d determines whether or not a request to set simulation parameters has been input (step S35). If it is determined that a request to set simulation parameters has not been input (NO in step S35), the process proceeds to step S37.

[0128] On the other hand, if it is determined that a request for setting simulation parameters has been input (YES in step S35), the display control unit 30d displays, for example, a simulation parameter setting area 33a4 (simulation parameter setting screen 33c) on the main screen 33a (see FIG. 8), and the setting control unit 30a executes a simulation parameter setting process on the simulation parameter setting screen 33c while accepting operation input from the operation unit 33 (step S36).

[0129] During the display process of the simulation parameter setting screen 33c in step S36 or after the display process is completed, for example, in a state where the display is returned to the main screen 33a, the display control unit 30d judges whether or not a setting confirmation request instructing to confirm the setting contents has been input (step S37). If it is judged that a setting confirmation request has not been input (NO in step S37), the process proceeds to step S39.

[0130] On the other hand, if it is determined that a setting confirmation request has been input (YES in step S37), the display control unit 30d causes the display unit 33 to display a setting confirmation screen corresponding to the request (step S38).

[0131] Regarding the processing of steps S37 and S38, when a simulation setting confirmation request is input in step S37, the display control unit 30d displays, in step S38, a simulation model setting screen 33b (see FIG. 9) having a simulation model display area 33b2 as shown in FIG 11, for example. When a connection confirmation / support request is input in step S37, the display control unit 30d displays, in step S38, a connection confirmation / support request screen 33d as shown in FIG 12, for example.

[0132] In a state where the various setting confirmation screen is displayed in the above step S38, the display control unit 30d judges whether or not an end request to instruct the end of the process has been input (step S39). If it is judged that an end request has not been input (NO in step S39), the display control unit 30d returns to step S31 in accordance with the instruction to return the process, displays the main screen 33a, and continues the process from step S31 onwards.

[0133] On the other hand, if it is determined that a termination request has been input (YES in step S39), the display control unit 30d terminates the above-described series of display controls in the setting stage.

[0134] Next, the display forms of the main screen 33a (see FIG. 8), the simulation model setting screen 33b (see FIG. 9, FIG. 10, FIG. 11), the simulation parameter setting screen 33c (see FIG. 8), and the connection confirmation / support screen 33d (see FIG. 12), which are displayed in each step of the series of display controls shown in FIG. 6, will be described in more detail.

[0135] As shown in FIG. 8, main screen 33a displayed in step S31 of FIG. 6 has a sequence display area 33a1, a connection state display area 33a2, a sequence log display area 33a3, and a simulation parameter setting area 33a4.

[0136] The sequence display area 33a1 has the same function as the sequence display section 6a in the configuration of the display section 6 shown in FIG. 25, and is an area that displays which sequence state (status) the terminal 11a to be measured is in, such as "Power Off", "Detach", "Registration", "Idle", "Origination", "Termination", "Communication", "UE (user equipment) Release", "NW (network) Release", "Handover", etc.

[0137] The connection status display area 33a2 is an area where the connection status between the terminal 11a and a virtual connection destination (non-standalone NR) via the measurement device 1A is displayed. This connection status display area 33a2 does not display the connection status when the number of RAT cells has not been set. In contrast, after the number of RAT cells has been set, the connection status according to the setting content is displayed. The connection status is displayed as an image simulating the connection status of both cells using an NR cell icon simulating an NR base station cell (hereinafter, NR cell) corresponding to the set cell in the NR area and an LTE cell icon simulating an LTE base station cell (hereinafter, LTE cell) corresponding to the set cell in the LTE area.

[0138] The sequence log display area 33a3 is an area for displaying a log relating to a sequence of the terminal 11a that is the measurement target, in association with each of the items of time stamp, sequence type, direction, and remarks (Date).

[0139] The simulation parameter setting area 33a4 is a display area as a simulation parameter setting screen 33c for setting simulation parameters related to the set NR cell and LTE cell after setting the number of RAT cells. The simulation parameter setting screen 33c can be displayed on the main screen 33a by, for example, clicking the connection status display area 33a2.

[0140] The simulation parameter setting screen 33c is configured to allow switching of the cell to be set, and allows setting of simulation parameters for all NR cells (e.g., NR1, NR2) and LTE cells (e.g., LTE1, LTE2, LTE3) corresponding to the NR cell icons and LTE cell icons whose connection status is displayed.

[0141] The simulation parameter setting screen 33c has, as setting items, common items common to NR and LTE, and specific items specific to each of NR and LTE. The common items include Cell Name, TRx Ref point, DL Ref Power, UE Rx Power, DL Pathloss, UL Ref Power, UE Tx Power, UL Pathloss, MCC, MNC, Call Identity, etc. The specific items (for example, in the case of an NR cell) include RS EPRE, Uplink Target Power Density, Duplex Mode, NR Band, Channel (DL), Frequency (DL), Channel (UL), Frequency (UL), DL Subcamer Spacing, UL Subcamer Spacing, DL BandWidth, UL BandWidth, etc.

[0142] The main screen 33a having the above configuration is displayed on the display unit 33 by display control of the display control unit 30d (see step S31 in FIG. 6). At this time, when the number of RAT cells has already been set, the display control unit 30d displays the connection state between the set cells in the connection state display area 33a2 of the main screen 33a, for example, in the form shown in FIG.

[0143] Here, the display control unit 30d displays one NR cell icon (first cell icon) indicating that the base station is a base station (NR cell) that complies with the NR communication standard, and one LTE cell icon (second cell icon) indicating that the base station is a base station that complies with the LTE communication standard, and displays a number of figures associated with the NR cell icon arranged in a row equal to the number of base stations that complies with the NR communication standard, and also displays a number of figures associated with the LTE cell icon arranged in a row equal to the number of base stations that complies with the LTE communication standard.

[0144] The display control unit 30d is also configured to display rectangular frames as figures, and to display within each rectangular frame a number for identifying a base station compatible with the NR communication standard and a number for identifying a base station compatible with the LTE communication standard. The figures may be displayed in the form of a box with a rectangular frame on one side, and the figures may be displayed in a vertically stacked form.

[0145] Specifically, in the example of FIG. 8, the display control unit 30d displays, for the connection state in the NR area among the connection state in the NR area and the cell connection state in the LTE area displayed in the connection state display area 33a2, a number of box shapes (box shapes with a rectangular frame on one side) corresponding to the NR cells in the NR area involved in the measurement of the terminal 11a, stacked vertically adjacent to one NR cell icon indicating a base station (NR cell) in the NR area. In this example, since two NR cells are set, the two box shapes are displayed as an image stacked vertically. A numerical value indicating the base station number of the NR cell is written in the rectangular frame of each box shape. In addition, the NR cell icon is marked with the symbol "NR" indicating the area type.

[0146] Furthermore, the display control unit 30d displays, for the connection state within the LTE area, a number of boxes corresponding to the LTE cells in the LTE area involved in the measurement of the terminal 11a, stacked vertically adjacent to one LTE cell icon indicating a base station (LTE cell) within the LTE area. In this example, since three LTE cells are set, an image of three boxes stacked vertically is displayed. A numerical value indicating the base station number of the LTE cell is written within the rectangular frame of each box. In addition, the LTE cell icon is marked with the LTE symbol "L" indicating the area type.

[0147] According to the display form of the connection state regarding the set NR cell and LTE cell shown in FIG. 8, even if the number of cells set in the NR area and LTE area increases, the number of NR cell icons and LTE cell icons does not increase, and the area displaying the rectangular frame in each area does not expand. In addition, although the area displaying the rectangular frame in each area may expand vertically according to an increase in the number of rows of the rectangular frame, the expansion can be suppressed compared to the case where cell icons imitating the shape of a base station are stacked. In addition, the rectangular frames may be arranged horizontally above or below the cell icon. In addition, it is not limited to one row, and multiple rows may be used.

[0148] Figure 8 shows an example in which rectangular frames are displayed in association with the NR cell icon and the LTE cell icon, the number of which corresponds to the number of base stations in the NR area and the number of base stations in the LTE area, respectively. However, instead of rectangular frames, various shapes may be displayed stacked vertically or arranged horizontally.

[0149] Thus, in the measurement device 1A of this embodiment, the display control unit 30d controls all cells (NR cells and LTE cells) in the NR area and LTE area involved in the measurement of the terminal 11a, the number of which varies depending on the scenario for simulating communication under the NR communication standard (setting of the combination of cells for simulated communication operation), to be displayed within a display area of ​​a predetermined size.

[0150] The simulation model setting screen 33b (see Fig. 9) displayed in step S33 in Fig. 6 includes, for example, a RAT cell number setting screen (RAT cell number setting area) 33b1, the screen configuration of which is shown in an enlarged scale in Fig. 10. The display control unit 30d can display the simulation model setting screen 33b including the RAT cell number setting screen 33b1 based on a simulation model setting request operation using a tab (GUI tool) on the main screen 33a.

[0151] In the measurement device according to the present embodiment, the display control unit 30d displays the RAT cell number setting screen 33b1 on the simulation model setting screen 33b as an image in which a tool for selecting the number of cells for each RAT type, NR or LTE, is arranged, as shown in Fig. 9 and Fig. 10. Specifically, the display control unit 30d displays the RAT cell number setting screen 33b1 in a screen configuration having a RAT field 35a in which a single NR cell icon indicating that the RAT (radio access technology; area type) is NR and a single LTE cell icon indicating that the RAT is LTE are arranged side by side, and a cell field 35b in which a cell number selection tool for selecting the number of cells for each RAT according to a scenario is provided at a position corresponding to the NR cell icon and the LTE cell icon, respectively.

[0152] In addition, in the display form shown in Figures 9 and 10, a RAT name column 35c is provided on the upper and lower opposite sides of each cell number selection tool that sandwiches the NR cell icon and the LTE cell icon, and in the RAT name column 35c, the RAT names "NR" and "LTE" corresponding to the NR cell icon and the LTE cell icon are written vertically.

[0153] In this embodiment, the RAT cell number setting screen 33b of the simulation model setting screen 33b has a RAT name column 35a, a RAT column 35b, and a cell column 35c, as shown in Fig. 10, and the number of cells of the corresponding RAT is selected by operating the cell number selection tool in the cell column 35b. With this configuration, even if the number of cells increases, there is no need to expand the display area. In addition, the simple screen configuration makes it easy to see and allows the number of cells to be easily set.

[0154] In addition to the above-mentioned RAT cell number setting screen 33b (see FIG. 10), the simulation model setting screen 33b (see FIG. 9) also includes a simulation model display area 33b2, the enlarged screen configuration of which is shown in FIG.

[0155] In the measurement device 1A according to the present embodiment, the display control unit 30d displays the simulation model display area 33b2 in a screen configuration in which display areas 35d and 35e corresponding to NR and LTE, respectively, are provided, as shown in Fig. 11. The display control unit 30d displays the simulation model in the display area 35d corresponding to NR in a manner in which one NR cell icon is added with a numerical value corresponding to the number of cells set in the NR area, and displays one LTE cell icon in a manner in which a numerical value corresponding to the number of cells set in the LTE area is added, for the simulation model display area 33b2 having the above screen configuration.

[0156] 11 shows a display form when one NR cell and three LTE cells are selected and set. In this case, the display control unit 30d performs display in the display area 35d in a form in which the NR cell icon with the abbreviation "N" corresponding to NR is displayed together with the symbol "x1" indicating that the number of NR cells is one. In addition, the display control unit 30d performs display in the display area 35e in a form in which the LTE cell icon with the abbreviation "L" corresponding to LTE is displayed together with the symbol "x3" indicating that the number of LTE cells is three.

[0157] In this way, the display control unit 30d displays one NR cell icon (first cell icon) corresponding to NR and LTE, respectively, and one LTE cell icon (second cell icon), and further displays a simulation model display area 33b2 having display areas 35d, 35e corresponding to NR base stations and LTE base stations, respectively, with display area 35d displaying an NR cell icon with a number corresponding to the number of NR base stations added, and display area 35e displaying an LTE cell icon with a number corresponding to the number of LTE base stations added.

[0158] In this embodiment, the simulation model display area 33b2 displays the simulation model in the form of a combination of one icon and the number of cells (numerical value) for each of the NR and LTE RATs, as shown in FIG. 11. This makes it possible to grasp all cells even when the number of NR cells and LTE cells increases.

[0159] In this embodiment, the simulation model setting screen 33b has a RAT cell number setting area 33b1 (RAT cell number setting screen) and a simulation model display area 33b2, so that the user can set the simulation model while checking the simulation model on the simulation model setting screen 33b.

[0160] The simulation parameter setting screen 33c used in setting the simulation parameters in step S36 in Fig. 6 can be displayed on the main screen 33a as a simulation parameter display area 33a3 by clicking on the connection status display area 33a2 on the main screen 33a, as shown in Fig. 8. The user can set the various parameters described above using this simulation parameter setting screen 33c.

[0161] Fig. 12 shows an example of a connection check and support request screen 33d displayed in step S38 when a connection check and support request is input in step S37 of Fig. 6. Fig. 12 particularly shows an example of a connection check and support request screen 33d displayed on the display unit 33 by the control device 22 when the NR measurement device 20 and the LTE measurement device 21 are connected and operated in the connection mode shown in Fig. 4.

[0162] As shown in FIG. 12, the connection confirmation / support request screen 33d has a screen configuration that displays adjacent to each other a first connection diagram image 33d1, which is an image that mimics the external structure of the front panel and rear panel of the NR measurement device 20 and allows the front panel and rear panel to be switched, and a second connection diagram image 33d2, which is an image that mimics the external structure of the front panel and rear panel of the LTE measurement device 21 and allows the front panel and rear panel to be switched.

[0163] The connection confirmation / assistance request screen 33d corresponds to the images of each connection terminal on the front panel and rear panel of the first connection diagram image 33d1 and the second connection diagram image 33d2, respectively, and displays the connection state of the connection terminal to the connection destination in a manner that indicates the name of the connection terminal.

[0164] The display control unit 30d of the control device 22 is configured to display an image that functions as a connection diagram by adding connection destination names that are changed in accordance with the settings (scenario) of the simulation parameters set in step S36 of Figure 6 to the images of each connection terminal on the front panel and rear panel of each of the first connection diagram image 33d1 and the second connection diagram image 33d2.

[0165] In the example of Fig. 12, the image of each connection terminal on the rear panel (similar to the front panel) of the first connection diagram image 33d1 is marked with the name of the other party, such as BTS1 Ant#1 Tx / Rx, BTS2 Ant#1 Tx / Rx, etc. Also, the image of each connection terminal on the front panel (similar to the rear panel) of the second connection diagram image 33d2 is marked with the name of the other party, such as LTE1 Ant#1 Tx / Rx to LTE3 Ant#1 Tx / Rx, LTE1 Ant#2 Tx to LTE3 Ant#2 Tx, etc. The display content of this connection check / support request screen 33d functions as a connection diagram including the connection state between the NR measurement device 20 and the LTE measurement device 21 and the measurement antennas (NR antennas and LTE antennas) corresponding to the antennas of the terminal 11a to be measured.

[0166] In this way, the display control unit 30d has the function of displaying a connection diagram that includes at least the connection state between the NR measurement device 20 and the LTE measurement device 21 and the measurement antenna corresponding to the antenna of the terminal 11a to be measured.

[0167] 12, the image of each connection terminal (different from the connection terminal described above) on the rear panel of the first connection diagram image 33d1 includes a connection destination name such as Ethernet and Sync Output, an indication suggesting a connection state with the LTE measurement device 21 corresponding to the second connection diagram image, and an indication including a connection destination name such as Control, an indication suggesting a connection state between the NR measurement device 20 and the LTE measurement device 21 and the control device 22. Therefore, the display control unit 30d also has a function of displaying a connection diagram further including a connection state between the NR measurement device 20 and the LTE measurement device 21, and a connection state between the NR measurement device 20 and the LTE measurement device 21 and the control device 22.

[0168] In this embodiment, the connection diagram is displayed in the form shown in FIG. 12, so that the connection state can be easily understood and the connection work can be performed easily and quickly.

[0169] Next, a display processing procedure during measurement by the terminal 11a will be described with reference to the flowchart shown in FIG.

[0170] In the measurement device 1A having the connection configuration shown in Fig. 4, after the control device 22 has completed the processes of setting the number of RAT cells, setting and checking the simulation model, and setting the simulation parameters (see S34 to S36 in Fig. 6), for example, the display is returned to the main screen 33a (step S41), and then the measurement control unit 30c of the control device 22 judges whether or not an instruction to start measurement of the terminal 11a has been input from the operation unit 32 (step S42). If it is judged that an instruction to start measurement has not been input (NO in step S42), the process proceeds to step S47.

[0171] On the other hand, if it is determined that an instruction to start measurement has been input (YES in step S42), the measurement control unit 30c comprehensively controls the NR measurement device 20 and the LTE measurement device 21 to start measuring the terminal 11a (step S43). When measuring the terminal 11a, the measurement control unit 30c captures signals transmitted and received between the terminal 11a to be measured and the measurement device 20 and the LTE measurement device 21, while controlling the measurement device 20 and the measurement device 21 to simulate the operation of each base station in the non-standalone NR according to a preset scenario (step S44), and measures the terminal 11a based on the captured signals. Meanwhile, the display control unit 30d changes and displays the measurement-related information on the main screen 33a, etc., reflecting the signals captured in step S43 (step S45).

[0172] As an example of the change display in step S45, the display control unit 30d displays the connection status of each of the NR area and LTE area in the non-standalone NR network in the connection status display area of ​​the main screen 33a. Specifically, the display control unit 30d displays, for example, as shown in Fig. 8, vertically stacked rectangular frames corresponding to the number of base stations corresponding to each area set in the current measurement adjacent to each BTS icon that resembles a base station in the NR area and the LTE area.

[0173] While displaying the main screen 33a changed in step S45, the display control unit 30d monitors whether the connection status area 33a1 of the main screen 33a has been selected (clicked) (step S45). If it is determined that the connection status area 33a1 of the main screen 33a has not been clicked (NO in step S45), the process proceeds to step S47.

[0174] On the other hand, when it is determined that the connection status area 33a1 of the main screen 33a has been clicked (YES in step S45), for example, a DC operation confirmation screen 33e shown in Fig. 13 is displayed on the display unit 33 (step S46). The DC operation confirmation screen 33e has a DC operation status display area 33e2 that displays an image of the operation status of the DC. In the example of Fig. 13, the display control unit 30d displays an image of the operation mode of the DC method in the NR area and the operation mode of the CA method in the LTE area in the DC operation status display area 33e2.

[0175] In addition, in the display process of step S46, it is also possible to display a DC operation confirmation screen 33f (see FIG. 14) having a screen structure different from that of the DC operation confirmation screen 33e. In this DC operation confirmation screen 33f, an operation mode by the DC method in the NR area and an operation mode by the CA method in the LTE area are displayed as images in the DC operation status display area 33e2.

[0176] During the display process of the DC operation confirmation screen 33e (or 33f) in step S46, or after the display process is completed, for example, in a state where the display is returned to the main screen 33a, the display control unit 30d judges whether or not an operation confirmation request for instructing to check the operation status related to the measurement of the terminal 11a has been input (step S47). If it is judged that an operation confirmation request has not been input (NO in step S47), the process proceeds to step S49.

[0177] On the other hand, if it is determined that an operation confirmation request has been input (YES in step S47), the display control unit 30d causes the display unit 33 to display an operation confirmation screen according to the request (step S48).

[0178] Regarding the processing of steps S47 and S48 in Fig. 7, when a test case confirmation request is input in step S47, the display control unit 30d displays, for example, a test case confirmation screen 33g as shown in Fig. 15 in step S48. When a component confirmation request is input in step S47, the display control unit 30d displays, for example, a component confirmation screen 33h as shown in Fig. 16 in step S48. Note that in response to the component confirmation request, it is also possible to display, for example, a component confirmation screen 33i as shown in Fig. 17.

[0179] Furthermore, if a power characteristics confirmation request, for example, is input in step S47, the display control unit 30d displays, in step S48, a power characteristics confirmation screen 33j as shown in FIG. 18, for example, and if a throughput confirmation request, for example, is input in step S47, the display control unit 30d displays, in step S48, a throughput confirmation screen 33k as shown in FIG. 19, for example.

[0180] In a state where the various operation confirmation screens are displayed in step S48, the display control unit 30d judges whether or not an end request to instruct the end of the process has been input (step S49). If it is judged that an end request has not been input (NO in step S49), the display control unit 30d returns to step S41 in accordance with the instruction to return the process, displays the main screen 33a, and continues the process from step S41 onwards.

[0181] On the other hand, if it is determined that a termination request has been input (YES in step S49), the display control unit 30d terminates the above-described series of display controls after the start of measurement by the terminal 11a.

[0182] Next, the display formats of the main screen 33a (see FIG. 8), DC operation confirmation screens 33e and 33f (see FIG. 13 and FIG. 14), test case confirmation screen 33g (see FIG. 15), component confirmation screens 33h and 33i (see FIG. 16 and FIG. 17), power characteristics confirmation screen 33j (see FIG. 18), and throughput confirmation screen 33k (see FIG. 19) related to the series of display controls shown in FIG. 7 will be explained in more detail.

[0183] The DC operation confirmation screens 33e (see FIG. 13) and 33f (see FIG. 14) displayed in step S46 can be displayed by, for example, clicking on the vicinity of the display area of ​​the NR cell icon and the LTE cell icon in the connection status display area 33a2 of the main screen 33a (see FIG. 8) after the terminal 11a starts measurement. The DC operation confirmation screens 33e and 33f each have an operation data display area 33e1 and an operation image display area 33e2. The DC operation confirmation screen 33e and the DC operation confirmation screen 33f are display examples in cases where the settings related to DC operation are different, and there is no difference in the screen configuration. The DC operation confirmation screen 33e shows a scroll state in which the operation data display area 33e1 is easy to see, and the DC operation confirmation screen 33f shows a scroll state in which the operation image display area 33e2 is easy to see.

[0184] As shown in Fig. 13 and Fig. 14, in the DC operation confirmation screens 33e and 33f, the operation data display area 33e1 has an NR operation data display area and an LTE operation data display area. The NR operation data display area displays detailed data related to the operation mode by the DC method that bundles CCs of different base stations in the NR area. The LTE operation data display area displays detailed data related to the operation mode by the CA method that bundles CCs of the same base station in the LTE area.

[0185] In addition, in the DC operation confirmation screens 33e and 33f, the operation mode by the DC method in the NR area and the operation mode by the CA method in the LTE area are displayed in the operation image display area 33e2 using an image showing each operation mode. For example, in the operation image display area 33e2 of the DC operation confirmation screen 33f shown in FIG. 14, an image in which one rectangular frame is added to the NR cell icon and three rectangular frames are added to the LTE cell icon is displayed, and an image showing a state in which the base station corresponding to the rectangular frame added to the NR cell icon and the three base stations corresponding to the three rectangular frames added to the LTE cell icon are communicating with the user device UE simulating the terminal 11a is displayed. In the operation image display area 33e2 of the DC operation confirmation screen 33e shown in FIG. 13, the same type of image is displayed, although it is difficult to see due to the scroll position.

[0186] In this way, the display control unit 30d has a display function for displaying an image showing an operation mode based on the DC scheme in an NR area and an operation mode based on the CA scheme in an LTE area.

[0187] In this embodiment, by using the display format shown in the operation image display area 33e2 in Figures 13 and 14, it becomes possible to easily grasp the operation status of the DC and CD formats in non-standalone NR.

[0188] Screens that may be displayed in step S48 of FIG. 7 include test case confirmation screen 33g (see FIG. 15), component confirmation screens 33h and 33i (see FIG. 16 and FIG. 17), power characteristics confirmation screen 33j (see FIG. 18), and throughput confirmation screen 33k (see FIG. 19).

[0189] The test case confirmation screen 33g is a screen for setting an arbitrary cell from among NR cells or LTE cells, and for confirming the radio situation of the set cell by performing a test measurement of the terminal 11a. For example, during the execution of the above-mentioned test measurement, the test case confirmation screen 33g can be displayed in a predetermined area on the main screen 33a in the form shown in FIG. 15 in response to a tab selection operation on the main screen 33a.

[0190] In the measurement device 1A of this embodiment, when the above-mentioned tab selection operation is performed, the display control unit 30d displays an image showing the radio conditions of the NR cell or LTE cell being set as a test case in the form shown in Figure 15 based on the setting contents of the number of RAT cells and the signal input from the NR measurement related information determination unit 13k of the pseudo base station control unit 4.

[0191] The test case confirmation screen 33g shown in Fig. 15 is particularly related to an LTE cell. At this time, the display control unit 30d draws an image in which an LTE cell icon with the abbreviation "L" for LTE is added with label text (identification information) consisting of the RAT name "LTE" and the base station number (BTS number) of the LTE cell. In the example of Fig. 15, an image in which a label text "LTE1" is added to an LTE cell icon is displayed. The image includes a line segment indicating, for example, an elliptical wireless range of the cell being set as a test case.

[0192] Similarly, for a test case screen 33g when an NR cell is set as a test case, the display control unit 30d draws an image of an NR cell icon with the NR abbreviation "N" and label text consisting of the RAT name "NR" and the BTS number of the NR cell "1, 2, 3...".

[0193] Thus, in this embodiment, the display control unit 30d displays a test case confirmation screen for checking the radio conditions of a cell set as a test case from among NR cells or LTE cells, and the test case confirmation screen 33g has a display function of drawing an image for each cell set as a test case, in which an NR cell icon or LTE cell icon corresponding to the RAT type is accompanied by identification information consisting of the RAT name and base station number of the cell.

[0194] In this embodiment, the test case confirmation screen 33g is displayed in a form in which label text consisting of "RAT name" and "BTS number" is added to the NR cell icon or LTE cell icon, so that even if the number of BTSs increases, there is no shortage of display space and ease of viewing is ensured.

[0195] The component confirmation screens 33h and 33i are screens for confirming the carrier operation status during measurement by the terminal 11a between cells set as a combination for executing a scenario, and have screen configurations, for example, as shown in Fig. 16 and Fig. 17, respectively. The component confirmation screens 33h and 33i are common in that they show CCs with carrier icons having, for example, rectangular shapes with rounded corners, but differ in how carriers are bundled for LTE. The component confirmation screen 33h shows an example of a case where carriers are bundled into one frequency band (band) in LTE, and the component confirmation screen 33i shows an example of a case where the above carriers are bundled into multiple bands (2 bands).

[0196] As shown in Fig. 16, the component confirmation screen 33h has a carrier operation display area 33h1 and a CA / DC setting condition display area 33h2. In the carrier operation display area 33h1, a carrier usage status between RAT cells being set is displayed using carrier icons. As shown in Fig. 16, the component confirmation screen 33h has a screen configuration in which component icons corresponding to several CCs, which are components of a bundled frequency band (band), are arranged to represent the bundled band.

[0197] Specifically, the component confirmation screen 33h has display areas 35f and 35g corresponding to the master node and the secondary node, respectively, secured within a carrier operation display area 33h1. In the upper master node display area 35f, an LTE cell icon is displayed next to the notation "Master Node", and below that, component icons corresponding to CCs bundled as Band1 are arranged horizontally and displayed separately for DL ​​(downlink) and UL (uplink). In the example of FIG. 16, for DL, three component icons corresponding to three CCs, which are radio resources of LTE1, LTE2, and LTE3, are displayed. For UL, a component icon corresponding to one CC, which is a radio resource of LTE1, is displayed.

[0198] All the component icons are, for example, rectangular with rounded corners, and are the same size. However, the component icon corresponding to the CC, which is the wireless resource of the master node, and the component icon corresponding to the CC, which is the wireless resource of the secondary node, are displayed in different colors. In FIG. 16, for example, those displayed in blue are hatched. Those not hatched are displayed in, for example, red.

[0199] Each component icon has identification information inside it that identifies the cell that is the source of the resource. For example, the identification information is a label text consisting of the RAT name and base station number. Above each component icon, a numerical value indicating the band of each corresponding CC (e.g., "10", in MHz) is written, and next to it, the total value of these (e.g., "30 MHz"). Below each component icon, a symbol indicating that the corresponding CCs are bundled together and the name of the band (e.g., Band 1) are written.

[0200] In the secondary node display area 35g below the master node display area 35f in the carrier operation display area 33h1, an NR cell icon is displayed next to the notation "Secondary Node", and below that, for example, a component icon corresponding to a CC bundled as BTsn77 is displayed. The display of the component icon in the secondary node display area is basically performed in the above-mentioned display form of the component icon in the master node display area.

[0201] 17 has a screen configuration including a carrier operation display area 33i1 and a CA / DC setting condition display area 33i2, similar to the component confirmation screen 33h. However, the configuration of the CA / DC setting condition display area 33i2 is different from the screen configuration of the CA / DC setting condition display area 33h2 in the component confirmation screen 33h.

[0202] In addition, the carrier operation display area 33i1 of the component confirmation screen 33i displays component icons in a manner different from that of the carrier operation display area 33h1 (see FIG. 16) in accordance with the configuration of the CA / DC setting condition display area 33i2. In the example of FIG. 17, the display form of the component icons related to DL in the master node display area 35f of the carrier operation display area 33i1 is different from that of the carrier operation display area 33h1. For DL ​​in the master node display area 35f of the carrier operation display area 33i1, the display is made in a manner that shows how Band1 corresponding to the radio resources of LTE1 and Band3 bundling the radio resources of LTE2 and LTE3 are used. The display form of the other parts of the carrier operation display area 33i1 is the same as that of the carrier operation display area 33h1.

[0203] Thus, in the measurement device 1A of this embodiment, the display control unit 30d displays a component confirmation screen in which component icons of the same shape indicating the CCs to be bundled based on the CA method and the DC method are arranged, and identification information consisting of the RAT name and base station number that are the resource source of the CC is displayed within the component icon, and the bandwidth of the CC is displayed above the component icon, and the component icons have a display function that displays them divided into master nodes and secondary nodes, and uplinks and downlinks.

[0204] Conventionally, there was a method for checking CC, for example, to change the width of the component icon according to the bandwidth value set for each BTS. Also, conventionally, only LTE-compatible image rendering was available for multi-cell.

[0205] In contrast, in this embodiment, as shown in Figures 16 and 17, component icons are unified to the same shape and displayed with the same width, identification information consisting of the RAT name and base station number is written inside the component icon, and the bandwidth is displayed above the component icon. Therefore, in this embodiment, even if the number of BTSs increases, the display area can be expanded horizontally, and the RAT type can be easily grasped.

[0206] The power characteristics confirmation screen 33j has a power characteristics display area 33j1, a power adjustment display area 33j2, and an operation status display area 33j3, as shown in Fig. 18, for example. The power characteristics display area 33j1 is an area that displays the power of the component carrier of the set cell using a graph with time on the horizontal axis and power on the vertical axis. The power adjustment display area 33j2 is an area that displays setting items for adjusting the power of the component carrier of each cell. The operation status display area 33j3 is an area that depicts an image of the operation status of each cell using images that mimic each cell and the terminal 11a to be measured.

[0207] The power characteristics check screen 33j can be displayed, for example, by a tab operation on the main screen 33a as necessary. In order to display the power characteristics check screen 33j, the control unit 31 (see FIG. 5) of the control device 22 is provided with a power detection function unit (not shown) that detects the power of each NR cell and component carrier that is a resource of the LTE cell, the combination of which is set according to the scenario, based on a signal (a signal transmitted between the terminal 11a during simulated communication) output by the NR-related measurement information determination unit 13k of the pseudo base station control unit 4. The power detection function unit may be provided in another location, for example, in the display control unit 30d.

[0208] The display control unit 30d is configured to plot the power characteristics (change characteristics of power value over time) of the component carrier of each NR cell and LTE cell detected by the power detection function unit as a graph in the power characteristics display area 33j1 corresponding to the NR cell and LTE cell.

[0209] Conventionally, this type of power characteristic display only supports LTE, and the power of each cell was not displayed in accordance with LTE and NR as in the present embodiment. According to the configuration of the present embodiment in which the power characteristics of the NR cell and the LTE cell are displayed on the same graph, it becomes possible to easily and reliably grasp the power characteristics of the NR cell and the LTE cell related to DC in non-standalone NR.

[0210] In addition, the display control unit 30d displays a graph showing the power characteristics of the NR cell and the LTE cell in the power characteristics display area 33j1 of the power characteristics confirmation screen 33j, and also draws an image of the operation status of the NR cell and the LTE cell in the operation status display area 33j3.

[0211] Here, for example, as shown in FIG. 18, when there are multiple base stations set as cells for performing simulated communication operations within an NR area and an LTE area, the display control unit 30d displays two NR cell icons and two LTE cell icons corresponding to the first and last base stations for each NR area and LTE area, respectively, side by side, and displays the two NR cell icons and two LTE cell icons associated with each icon in a form in which the RAT name is followed by the first base station number and the last base station number, separated by a comma.

[0212] Specifically, in the example of Fig. 18, the display control unit 30d displays the NR area by arranging two NR cell icons with the symbol "NR" next to each other, and below both NR cell icons, the first base station number "1" and the next base station number "2" are displayed, for example, separated by a comma, following "NR". Similarly, for the LTE area, the display control unit 30d displays two LTE cell icons with the abbreviation [L] for LTE next to each other, and below both LTE cell icons, the first base station number "1" and the next base station number "3" are displayed, for example, separated by a comma, following "LTE".

[0213] As a variant in this case, when three or more cells are set, the display control unit 30d may change the display form relating to "NR1,2" and "LTE1,2,3" in FIG. 18 to "NR1-3", "LTE1-5", etc. by connecting the first base station number and the last base station number, for example, with a line segment.

[0214] In this way, in the measurement device 1A according to the present embodiment, when there are multiple base stations set as cells in the NR area and the LTE area, the display control unit 30d has a function of displaying two BTS icons (NR cell icon and LTE cell icon) corresponding to the first and last base stations for each NR area and LTE, side by side, and displaying the two NR cell icons (first cell icon) and the two LTE cell icons (second cell icon) in a manner in which one piece of identification information is added in which the first base station number and the last base station number are separated and arranged following the RAT name. By having this function, it is possible to support non-standalone NR and to easily grasp the operating status of the NR cell and the LTE cell.

[0215] The throughput confirmation screen 33k has a throughput display area 33k1 and a carrier operation status display area 33k2, as shown in Fig. 19. The throughput display area 33k1 is an area that displays the throughput of each component carrier listed in the carrier operation status display area 33k2 using a graph with time on the horizontal axis and throughput (unit: kbps, for example) on the vertical axis.

[0216] The throughput confirmation screen 33k can be displayed, for example, by a predetermined tab operation on the main screen 33a. In order to display the throughput confirmation screen 33k, the control unit 31 (see FIG. 5) of the control device 22 is provided with a throughput measurement function unit that detects the throughput of each NR cell and component carrier, which is a radio resource of an LTE cell, whose combination is set according to a scenario, based on a signal (a signal transmitted between the terminal 11a during simulated communication) output by the NR-related measurement information decision unit 13k of the pseudo base station control unit 4. The throughput measurement function unit may be provided in another location, for example, the display control unit 30d.

[0217] The display control unit 30d is configured to plot the throughput characteristics of the component carriers used by each NR cell and LTE cell detected by the throughput detection function unit as a graph in the manner shown in Figure 19 in the throughput display area 33k1.

[0218] Conventionally, the display of the throughput characteristics of component carriers has generally been compatible only with LTE, and the throughput characteristics of NR cells and LTE cells have not been displayed in one place in accordance with LTE and NR as in the present embodiment. According to the configuration of the present embodiment in which the throughput characteristics of carriers, which are radio resources of NR cells and LTE cells, are displayed in one place as a graph, it becomes possible to easily and reliably grasp the throughput characteristics of the carriers of NR cells and LTE cells related to DC in non-standalone NR.

[0219] As described above, the measurement device 1A according to this embodiment tests the terminal 11a by simulating three or more base stations, and the three or more base stations include an NR base station corresponding to the NR communication standard and an LTE base station corresponding to the LTE communication standard. The measurement device 1A includes a transceiver unit 3 that transmits and receives signals of the NR communication standard between the NR base station and the terminal 11a, and transmits and receives signals of the LTE communication standard between the LTE base station and the terminal 11a, a pseudo base station control unit 4 that controls the transceiver unit 3 to execute a simulated communication operation that simulates communication between the terminal 11a and three or more base stations, and a display control unit 30d that displays on the display unit 33 measurement-related information related to the measurement of the terminal 11a based on signals transmitted and received between the terminal 11a during the simulated communication operation. The display control unit 30d has a configuration in which one NR cell icon indicating that the base station is compatible with the NR communication standard and one LTE cell icon indicating that the base station is compatible with the LTE communication standard are displayed in an arrayed state in association with the NR cell icon, and the same number of figures as the number of base stations compatible with the NR communication standard are displayed in an arrayed form in association with the LTE cell icon.

[0220] With this configuration, the measuring device 1A according to the present embodiment only needs to display one NR cell icon and one LTE cell icon at a time, and can save the display area even if the number of NR base stations and LTE base stations increases. Also, all base stations can be displayed graphically in association with the NR cell icon and the LTE cell icon, respectively.

[0221] In addition, in the measurement device 1A of this embodiment, the display control unit 30d displays rectangular frames as figures, and for each rectangular frame, displays a number for identifying an NR base station and a number for identifying an LTE base station within each frame.

[0222] With this configuration, the measuring device 1A according to the present embodiment can display NR base stations and LTE base stations in rectangular frames in association with NR cell icons and LTE cell icons, thereby saving the display area. In addition, the number displayed in the rectangular frame allows the user to easily grasp the number of all base stations.

[0223] In addition, in the measurement device 1A according to the present embodiment, the figure shows a box shape with a rectangular frame on one side, and the figure is displayed in a vertically stacked form. With this configuration, even if the number of NR base stations and LTE base stations increases, the measurement device 1A according to the present embodiment can prevent the entire display area from expanding, since the number of stacked rectangular frames associated with the NR cell icon and the LTE cell icon only changes.

[0224] In addition, the measurement device 1A of this embodiment tests the terminal 11a by simulating four or more base stations, where the four or more base stations include an NR base station corresponding to the NR communication standard and an LTE base station corresponding to the LTE communication standard, and is equipped with a transceiver unit 3 that transmits and receives signals of the NR communication standard between the NR base station and the terminal 11a, and also transmits and receives signals of the LTE communication standard between the LTE base station and the terminal 11a, a pseudo base station control unit 4 that controls the transceiver unit 3 to perform a simulated communication operation that simulates communication between the terminal 11a and four or more base stations, and a display control unit 30d that displays on the display unit 33 measurement-related information regarding the measurement of the terminal 11a based on signals transmitted and received between the terminal 11a during the simulated communication operation, two NR cell icons indicating that the terminal 11a is an NR base station, and two LTE cell icons indicating that the terminal 11a is an LTE base station.

[0225] With this configuration, the measurement device 1A of this embodiment only needs to display two NR cell icons and two LTE cell icons at all times, and the display area can be prevented from expanding according to the number of NR base stations and LTE base stations.

[0226] In addition, the measuring device 1A of this embodiment has a configuration in which the two NR cell icons are an NR cell icon corresponding to the base station with the first number of the NR base station and an NR cell icon corresponding to the base station with the last number of the NR base station, and the two LTE cell icons are an LTE cell icon corresponding to the base station with the first number of the LTE base station and an LTE cell icon corresponding to the base station with the last number of the LTE base station, and is associated with the two NR cell icons and displays information identifying the NR communication standard and the first and last numbers of the NR base station separated from each other, and is associated with the two LTE cell icons and displays information identifying the LTE communication standard and the first and last numbers of the LTE base station separated from each other.

[0227] With this configuration, the measuring device 1A of this embodiment can display images of all base stations within a limited display area by combining and displaying information identifying the NR or LTE communication standard associated with two NR cell icons and two LTE cell icons, respectively, and a representation of the first and last numbers of the NR base station or LTE base station separated from each other.

[0228] In addition, the measurement device 1A of this embodiment has a configuration in which the display control unit 30d displays the first and last base station numbers shown in each of two NR cell icons and two LTE cell icons in such a manner that a line is drawn between them to indicate that the consecutive base station numbers between the first and last base station numbers have been omitted.

[0229] With this configuration, the measuring device 1A of this embodiment can display images of all base stations within a limited display area by displaying the first and last numbers of the NR base station or LTE base station associated with two NR cell icons and two LTE cell icons, respectively, connected to each other by a line.

[0230] Moreover, the measurement device 1A according to the present embodiment tests the terminal 11a by simulating three or more base stations, the three or more base stations including an NR base station compatible with the NR communication standard and an LTE base station compatible with the LTE communication standard, and includes a transceiver unit 3 that transmits and receives signals of the NR communication standard between the NR base station and the terminal 11a and also transmits and receives signals of the LTE communication standard between the LTE base station and the terminal 11a, a pseudo base station control unit 4 that controls the transceiver unit 3 to execute a simulated communication operation simulating communication between the terminal 11a and the three or more base stations, and a measurement unit related to the measurement of the terminal 11a based on signals transmitted and received between the terminal 11a and the terminal 11a during the simulated communication operation. The display control unit 30d displays fixed related information on the display unit 33, and the display control unit 30d displays one NR cell icon indicating that it is an NR base station and one LTE cell icon indicating that it is an LTE base station, and further displays a simulation model display area 33b2 having display areas 35d, 35e corresponding to the NR base station and the LTE base station, respectively, and the display area 35d displays an NR cell icon with a numerical value corresponding to the number of NR base stations, and the display area 35e displays an LTE cell icon with a numerical value corresponding to the number of LTE base stations.

[0231] With this configuration, the measurement device 1A according to the present embodiment can save display area by displaying each of the NR cell icon and the LTE cell icon in the display area 35d and the display area 35e in the simulation model display area 33b2 with a numerical value added to each of them. Also, the number of base stations can be easily grasped from the numerical value added to the NR cell icon and the LTE cell icon.

[0232] Moreover, the measurement device 1A according to the present embodiment is a mixture of the first communication standard, NR, and the second communication standard, LTE. With this configuration, the measurement device 1A according to the present embodiment can be applied to the measurement of the terminal 11a in non-standalone NR operation, and even if the number of NR and LTE base stations increases, the display area can be saved and all base stations can be displayed in an image within a limited display area.

[0233] Furthermore, the communication terminal measurement system 1B according to this embodiment tests the terminal 11a by simulating three or more base stations, the three or more base stations including an NR base station compatible with the NR communication standard and an LTE base station compatible with the LTE communication standard, and includes an NR measurement device 20 having a first transceiver unit 3 for transmitting and receiving signals of the NR communication standard between the NR base station and the terminal 11a, an LTE measurement device 21 having a second transceiver unit 3 for transmitting and receiving signals of the LTE communication standard between the LTE base station and the terminal 11a, and a communication terminal measurement device 22 having the first transceiver unit 3 and the second transceiver unit 3 for executing a simulated communication operation simulating communication between the terminal 11a and the three or more base stations. The control device 22 has a simulated base station control unit 4 that controls the terminal 11a and a display control unit 30d that displays on the display unit 33 measurement-related information regarding the measurement of the terminal 11a based on signals transmitted and received between the terminal 11a and the terminal 11a during simulated communication operation. The display control unit 30d is configured to display one NR cell icon indicating that it is an NR base station and one LTE cell icon indicating that it is a base station compatible with the LTE communication standard, and to display, in association with the NR cell icon, a number of figures equal to the number of NR base stations in an arranged form, and to display, in association with the LTE cell icon, a number of figures equal to the number of LTE base stations in an arranged form.

[0234] With this configuration, the communication terminal measurement system 1B according to the present embodiment only needs to display one NR cell icon and one LTE icon at a time, and can save the display area even if the number of NR base stations and LTE base stations increases. Also, all base stations can be displayed graphically in association with the NR cell icon and the LTE cell icon, respectively.

[0235] In addition, in the communication terminal measurement system 1B of this embodiment, the display control unit 30d has a configuration that displays rectangular frames as figures and, for each rectangular frame, displays a number for identifying an NR base station and a number for identifying an LTE base station within each frame.

[0236] With this configuration, the communication terminal measurement system 1B according to the present embodiment can display NR base stations and LTE base stations in rectangular frames in association with NR cell icons and LTE cell icons, thereby saving display area. In addition, the number displayed in the rectangular frame allows the user to easily grasp the number of all base stations.

[0237] In addition, the communication terminal measurement system 1B according to the present embodiment has a configuration in which the figure shows a box shape with a rectangular frame on one side, and the figure is displayed in a vertically stacked form. With this configuration, the communication terminal measurement system 1B according to the present embodiment can prevent the entire display area from expanding even if the number of NR base stations and LTE base stations increases, by only changing the number of stacked rectangular frames associated with the NR cell icon and the LTE cell icon.

[0238] Moreover, the communication terminal measurement system 1B according to the present embodiment tests the terminal 11a by simulating four or more base stations, the four or more base stations including an NR base station compatible with the NR communication standard and an LTE base station compatible with the LTE communication standard, and includes an NR measurement device 20 having a first transceiver unit 3 for transmitting and receiving signals of the NR communication standard between the NR base station and the terminal 11a, an LTE measurement device 21 having a second transceiver unit 3 for transmitting and receiving signals of the LTE communication standard between the LTE base station and the terminal 11a, and a first transceiver unit 3 for executing a simulated communication operation simulating communication between the terminal 11a and the four or more base stations. The device is equipped with a control device 22 having a simulated base station control unit 4 that controls the first transceiver unit 3 and the second transceiver unit 4, and a display control unit 30d that displays measurement-related information regarding the measurement of terminal 11a based on signals transmitted and received between terminal 11a and the terminal 11a during simulated communication operation on a display unit 33, where there are two or more NR base stations and two or more LTE base stations, each identified by a number, and the display control unit 30d is configured to display, on the display unit 33, the measurement-related information regarding the measurement of terminal 11a based on signals transmitted and received between terminal 11a and the terminal 11a during simulated communication operation, two NR cell icons lined up, and two LTE cell icons lined up.

[0239] With this configuration, the communication terminal measurement system 1B of this embodiment only needs to display two NR cell icons and two LTE cell icons at all times, and the display area can be prevented from expanding according to the number of NR base stations and LTE base stations.

[0240] In addition, the communication terminal measurement system 1B of this embodiment has a configuration in which the two NR cell icons are an NR cell icon corresponding to the base station with the first number of the NR base station and an NR cell icon corresponding to the base station with the last number of the NR base station, and the two LTE cell icons are an LTE cell icon corresponding to the base station with the first number of the LTE base station and an LTE cell icon corresponding to the base station with the last number of the LTE base station, and is associated with the two NR cell icons and displays information identifying the NR communication standard and the first and last numbers of the NR base station separated from each other, and is associated with the two LTE cell icons and displays information identifying the LTE communication standard and the first and last numbers of the LTE base station separated from each other.

[0242] Furthermore, in the communication terminal measurement system 1B of this embodiment, the display control unit 30d is configured to display the first and last base station numbers shown in each of two NR cell icons and two LTE cell icons, connected by a line indicating that the consecutive base station numbers between the first and last base station numbers have been omitted.

[0243] With this configuration, the communication terminal measurement system 1B of this embodiment can display all base stations within a limited display area in an image by representing the first and last numbers of base stations corresponding to the NR or LTE communication standards, which are associated with two NR cell icons and two LTE cell icons, respectively, connected by a line.

[0244] Furthermore, the communication terminal measurement system 1B according to this embodiment tests the terminal 11a by simulating three or more base stations, the three or more base stations including an NR base station compatible with the NR communication standard and an LTE base station compatible with the LTE communication standard, and includes an NR measurement device 20 having a first transceiver unit 3 for transmitting and receiving signals of the NR communication standard between the NR base station and the terminal 11a, an LTE measurement device 21 having a second transceiver unit 3 for transmitting and receiving signals of the LTE communication standard between the LTE base station and the terminal 11a, and a communication terminal measurement device 22 having the first transceiver unit 3 and the second transceiver unit 3 for executing a simulated communication operation simulating communication between the terminal 11a and the three or more base stations.

[0245] With this configuration, the communication terminal measurement system 1B according to the present embodiment can save display area by displaying each of the NR cell icon and the LTE cell icon with a numerical value added in both the display area 35d and the display area 35e in the simulation model display area 33b2. Also, the number of base stations can be easily grasped from the numerical value added to the NR cell icon and the LTE cell icon.

[0246] Moreover, the communication terminal measurement system 1B according to the present embodiment is a mixture of the first communication standard, NR, and the second communication standard, LTE. With this configuration, the communication terminal measurement system 1B according to the present embodiment can be applied to the measurement of the terminal 11a in non-standalone NR operation, and even if the number of NR and LTE base stations increases, the display area can be saved and all base stations can be displayed in an image within a limited display area.

[0247] In addition, the measurement-related information display method of this embodiment is a measurement-related information display method that displays measurement-related information regarding the measurement of terminal 11a by simulating three or more base stations including base stations corresponding to the NR communication standard and the LTE communication standard, and includes a reception step S34 that accepts the setting of a combination of an NR base station corresponding to the NR communication standard and an LTE base station corresponding to the LTE communication standard, and a display control step S44 that includes one NR cell icon indicating that it is an NR base station and one LTE cell icon indicating that it is an LTE base station within a connection status display area 33a2 of a predetermined size based on the combination of the NR base station and the LTE base station accepted in the reception step S43, and associates the NR cell icon and the LTE cell icon with each other, and displays a form in which figures corresponding to the number of NR base stations and the number of LTE base stations, respectively, are arranged side by side.

[0248] With this configuration, the measurement-related information display method according to the present embodiment only needs to display one NR cell icon and one LTE cell icon at a time in the display control step S44, and can save the display area even if the number of NR base stations and LTE base stations increases. Also, all base stations can be displayed graphically in association with the NR cell icon and the LTE cell icon, respectively.

[0249] This embodiment illustrates an example of an operation mode in which 5GNR and LTE are mixed, but it can also be applied to an operation mode in which LTE and pre-LTE are mixed, or in the future, 5GNR and the next communication standard are mixed. [Industrial Applicability]
