  Hereinafter, a test system 100 according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows a block configuration of a test system 100 according to an embodiment of the present invention. The test system 100 includes two pseudo base station apparatuses, a pseudo base station apparatus (# 1) 51 and a pseudo base station apparatus (# 2) 52. Here, the symbols # 1 and # 2 are used only for distinguishing the two pseudo base station apparatuses, and do not mean a relationship such as master-slave.

  A mobile communication terminal device 70 (also simply referred to as “mobile communication terminal”) 70 of the terminal under test and a pseudo base station device 51 or a pseudo base station device 52 are connected via a coupler 60 via a coaxial cable. . An RF signal is used as a signal flowing through the coaxial cable. However, when a test as a chip set is performed instead of a test as the mobile communication terminal device 70, a digital IQ signal of the base band is used instead of the RF signal. May be.

  The combiner 60 combines and distributes signals transmitted and received between the mobile communication terminal device 70 and the pseudo base station devices 51 and 52. However, an antenna is provided in the mobile communication terminal device 70 without using the coupler 60, and the mobile communication terminal device 70 and the pseudo base station device 51 or the pseudo base station device 52 are connected by radio signals. Also good.

  The mobile communication terminal device 70 corresponds to one or more communication methods. As communication methods, GSM (registered trademark) (Global System for Mobile Communications), W-CDMA (Wideband-Code Division Multiple Access) can be used. ), CDMA2000 (Code Division Multiple Access 2000), LTE (Long Term Evolution), EVDO (Evolution Data Only), TD-SCDMA (Time Division Synchronous Code Division Multiple Access), and the like.

The RAM stores a program necessary for controlling one or more communication methods as described above of the mobile communication terminal device 70, and a test signal according to the communication method is stored in the mobile communication terminal device 70. Send. Each of the pseudo base station devices 51 and 52 receives a response signal to the test signal from the mobile communication terminal device 70 and analyzes the signal.

  The test system 100 includes a communication facing device (hereinafter also referred to as “server”) 20 as a communication destination designated by the mobile communication terminal device 70. The communication facing device 20 has a server computer function connected to a network, for example, and in response to a request from the mobile communication terminal device 70 serving as a client, the mobile communication terminal device 70 is tested for image data, for example.

  A relay device 40 is connected between the communication facing device 20 and the pseudo base station device 51 and the pseudo base station device 52. A switching hub or router may be used as the relay device 40. The relay device 40 functions as a bridge, analyzes the data sent from the mobile communication terminal device 70 or the communication facing device 20 to detect the destination, and sends it to the communication facing device 20 or the mobile communication terminal device 70 that is the destination. Send data. For this reason, the relay device 40 includes an address management table 40t.

  Further, an address resolution device 30 is connected between the communication facing device 20 and the relay device 40. The address resolution device 30 performs address resolution at the time of communication between the communication facing device 20 and the pseudo base station devices 51 and 52. In particular, as will be described in detail later, the pseudo base station device 51 and the pseudo base station When the station device 52 disguises the same IP address and a handover or an interlat (hereinafter referred to as “handover” or the like) is executed, the connection destination pseudo base station device of the mobile communication terminal device 70 changes. The address of the previous pseudo base station apparatus is resolved. Therefore, the address resolution device 30 has an ARP table 30t.

  Further, the test system 100 includes a test control device 10. The test control device 10 controls the operation of each of the above devices in the test system 100. Based on the control signal, the pseudo base station device 51 and the pseudo base station device 52 execute predetermined test communication with the mobile communication terminal device 70 in accordance with a scenario indicating the stored communication procedure and test procedure. For example, a test for confirming an error rate by a PN signal is applicable.

  FIG. 2 shows a block diagram of the address resolution device 30. The address resolution device 30 includes a transfer processing unit 32 that transfers signals between the communication facing device 20 and the mobile communication terminal device 70. The transfer processing unit 32 is connected to the communication facing device 20 and the relay device 40 via the communication facing device side I / F 31 and the relay device side I / F 33 having a communication speed of 1 Gbps, respectively.

  In the transfer processing unit 32, for communication with the communication opposite device 20, the address information of the communication opposite device side I / F that stores the setting information storage unit 34 of the communication opposite device side I / F and the server side ARP table is stored. An information storage unit 35 is connected. In addition, for the communication with the relay device 40, the transfer processing unit 32 sets the relay device side I / F setting information storage unit 37 and the address resolution information of the relay device side I / F that stores the HUB side ARP table. A storage unit 36 is connected. Those storage units are connected to the test control apparatus 10 via the control unit 39.

  Next, a procedure executed in the test system 100 to establish communication between the communication facing device 20 and the mobile communication terminal device 70 will be described with reference to FIGS. 3 and 4 to 11. Briefly, the IP address of the mobile communication terminal device 70 is set in both the pseudo base station devices 51 and 52, but the communication opposing device 20 and the mobile communication are set via one of the pseudo base station devices 51 and 52. Communication is performed between the terminal device 70 and then a handover is performed, and communication is performed between the communication facing device 20 and the mobile communication terminal device 70 via the other of the pseudo base station devices 51 and 52. To do.

  This will be described in detail. In step S 10, the same IP address as the IP address of the mobile communication terminal device 70 is set (impersonated) in the setting information storage unit 34 of the communication facing device side I / F by the operation unit 38 of the address resolution device 30. For example, if the IP address of the mobile communication terminal device 70 is 192.168.0.1, the same 192.IP address as the IP address of the communication facing device side I / F of the address resolution device 30 is stored in the setting information storage unit 34. 168.0.1 is stored.

  Next, in step S10, the same IP address as the IP address of the mobile communication terminal device 70 is set (impersonated) in both the pseudo base station devices 51 and 52, and the address resolution device 30 is set in the pseudo base station device 52. Is set so as not to respond to the ARP request. Further, the same IP address as that of the communication facing device 20 is set (impersonated) in the setting information storage unit 37 of the relay device side I / F by the operation unit 38 of the address resolution device 30. For example, when the IP address of the communication facing device 20 is 192.168.0.2, the same 192.168.8.0 is set as the IP address of the relay device side I / F of the address resolution device 30 in the setting information storage unit 37. .2 is memorized.

  The state after each setting in step S10 is shown in FIG. As shown in the figure, the same 192.168.0.1 as the IP address of the UE (mobile communication terminal device 70) is set in the BTS # 1, # 2 (pseudo base station devices 51, 52). However, the MAC addresses of BTS # 1 and # 2 are YYY and ZZZ, respectively.

  Note that the MAC address is originally a 48-bit code, but is simplified here for ease of explanation.

  Also, BTS # 1 and # 2 are connected to ports 1 and 2 of the HUB (relay device 40), respectively, and an address resolution device (address resolution device 30) is connected to port 0 of the HUB. The IP address of the relay device side I / F (relay device side I / F 33) of the address resolution device is set to 192.168.0.2 which is the same as the IP address of the server (communication opposite device 20). The IP address of the communication opposite device side I / F (communication opposite device side I / F 31) is set to 192.168.0.1, which is the same as the IP address of the UE.

  The MAC address of the relay device side I / F 32 of the address resolution device 30 is XXX. Description of the MAC address of the server (communication opposite device 20) and the MAC address of the communication opposite device side I / F 31 of the address resolution device 30 is omitted.

  Returning to FIG. 3, step S20 will be described. In step S20, a connection path is established between the server (communication opposite device 20) and the address resolution device 30. That is, in FIG. 5, the server can be transmitted to the address resolution apparatus by the Ethernet (registered trademark) protocol, and can be transmitted to the address resolution apparatus having a predetermined MAC address. The state where the connection path is established is indicated by a white arrow.

  When establishing a connection path from the address resolution device to the server, the address resolution device issues an ARP request to the server, and the server side ARP table (ARP table 30t) of the address resolution device is updated by the response. , 192.168.0.2 and a predetermined address are held as an IP address and a MAC address, respectively (not shown). On the other hand, the HUB side ARP table (ARP table 30t) and the HUB address management table (address management table 40t) of the address resolution device have not been updated yet.

  Here, ARP (Address Resolution Protocol) will be described. ARP is a protocol for acquiring a MAC address corresponding to an IP address in an Ethernet (registered trademark) environment. In the Ethernet (registered trademark) environment, since transmission / reception is performed using a MAC address, it is necessary to associate an IP address with a MAC address, so ARP is used. As an example, a case where transmission is performed from one device (node A) to another device (node B) will be described. Node A knows the IP address of node B, but the MAC address is unknown. Here, the node A transmits an ARP request by broadcasting. The ARP request stores information on the IP address and MAC address of node A, which is the transmission source, and the IP address of node B, which is the communication partner. The node B that has received this ARP request transmits to the node A an ARP response in which the information of its own MAC address is added to the aforementioned information stored in the ARP request. The node A can acquire the MAC address of the node B by receiving this ARP response, thereby enabling the communication between the node A and the node B.

  Returning to FIG. 3, in step S30, a connection path is established between the address resolution device 30 and the pseudo base station device (# 1) 51. That is, as shown by the white arrow in FIG. 6, when an address resolution request (ARP request) is issued from the address resolution device to BTS # 1 and # 2, only BTS # 1 responds to the request (ARP response). ). This is because BTS # 2 is set not to respond to the ARP request from the address resolution device in step S10. As a result, the HUB side ARP table of the address resolution device is updated, and 192.168.0.1 and YYY are held in the IP address column and the MAC address column, respectively. Also, the HUB address management table is updated to hold the MAC addresses XXX and YYY corresponding to the ports 0 and 1, respectively. Although port 2 is connected to BTS # 2, since BTS # 2 is set not to respond to the ARP request from the address resolution device in step S10, the MAC address column of port 2 is not updated.

  As a result of step S30, in step S40, communication is established between the server and the mobile communication terminal device 70 (terminal). That is, as shown in FIG. 7, communication is established between the server and the UE (mobile communication terminal device 70) as indicated by an open arrow.

  More specifically, when a signal from the server is transmitted to the address resolution device, the communication data has an IP address and a MAC address of 192.168.8.0. According to the contents of the HUB side ARP table of the address resolution device. 1 and YYY addressed to BTS # 1. At that time, according to the HUB address management table of the relay device 40, the communication data is transmitted to the BTS # 1 corresponding to the MAC address YYY via the port 1 of the relay device 40. An RF signal is transmitted from BTS # 1 to the UE having the IP address 192.168.0.1 via the coupler.

  Communication data addressed to the server from the UE is transmitted along an already established communication path. That is, the communication data is input from the UE to the BTS # 1 with the IP address 192.168.0.1 via the coupler, and input from the BTS # 1 to the port 1 of the HUB. Therefore, this signal is transmitted via the port 0 to the address resolution device whose MAC address is XXX according to the HUB address management table. In the address resolution device, the communication data is transmitted to a server having the MAC address with reference to the IP address and MAC address of the server held in the server-side ARP table.

  Next, in step S50, a handover or the like is performed. For example, the transmission power of the pseudo base station apparatus 51 is raised while the transmission power of the pseudo base station apparatus 51 is lowered. Thereby, as shown in FIG. 8, the connection between the mobile communication terminal apparatus 70 and the pseudo base station apparatus 50 is switched from the connection between the UE and the BTS # 1 to the connection between the UE and the BTS # 2. During this switching, the connection between the UE and BTS # 1 is maintained until the switching between the UE and BTS # 2 is completed.

  Subsequently, in step S60, when the test control apparatus 10 receives a completion notification such as a handover from the pseudo base station apparatus 52 after executing step S50, the test control apparatus 10 sends an ARP request to the pseudo base station apparatus 51. While setting not to respond, the pseudo base station apparatus 52 is set to respond to the ARP request. Further, the test control apparatus 10 initializes the HUB side ARP table of the address resolution apparatus.

  As a result, as shown in FIG. 9, communication is established between the UE and BTS # 2, while communication between the UE and BTS # 1 is blocked. Further, the HUB side ARP table of the address resolution device is initialized, and the relationship between the port and the MAC address is maintained as it is without updating the HUB address management table.

  Subsequently, in step S70, a connection path is established between the address resolution device 30 and the pseudo base station device 52. For this purpose, an ARP request is issued from the address resolution device 30 to the pseudo base station devices 51 and 52, as indicated by the white arrows in FIG. In response to this, the pseudo base station apparatus 52 returns the MAC address ZZZ. The pseudo base station apparatus 51 is set not to respond to the ARP request in step S60.

  Thereby, as shown in FIG. 10, the HUB side ARP table of the address resolution device is updated, and 192.168.0.1 and ZZZ are held in the IP address column and the MAC address column, respectively. In addition, the HUB address management table is updated, and the MAC address ZZZ is added to the port 2. Note that port 1 of the HUB is connected to BTS # 1, but BTS # 1 is set not to respond to the ARP request from the address resolution device in step S60, so port 1 is not used. become.

  In step S80, communication is established between the server 20 and the mobile communication terminal device 70. That is, as shown in FIG. 11, first, communication data from the server is sent to the address resolution device of the MAC address XXX between the server and the UE, as indicated by a white arrow. Next, the communication data is transmitted to the IP address 192.168.0.1 and the MAC address ZZZ shown in the HUB side ARP table of the address resolution device. At this time, communication data is input from the port 0 to the HUB, and is transmitted from the port 2 to the BTS # 2 having the MAC address ZZZ with reference to the HUB address management table. An RF signal is transmitted from BTS # 2 to the UE having the IP address 192.168.0.1 via the coupler.

  Communication data addressed to the server from the UE is transmitted along the established communication path. That is, the communication data is transmitted from the UE to the BTS # 2 of the IP address 192.168.0.1 whose connection is switched via the coupler, and is transmitted from the BTS # 2 to the port 2 of the HUB. In the HUB, based on the contents of the HUB address management table, the communication data is transmitted to the address resolution device having the MAC address XXX via the port 0. In the address resolution device, the signal is sent to a server having an IP address 192.168.0.2 and a predetermined MAC address held therein with reference to the server-side ARP table.

  According to this embodiment of the present invention, even when the same IP address as the IP address of the mobile communication terminal device 70 is set in the plurality of pseudo base station devices 50, only through a specific pseudo base station device. In order to enable communication between the mobile communication terminal apparatus 70 and the communication facing apparatus 20 such as a server, the pseudo base station apparatus to which the mobile communication terminal apparatus 70 is connected by handover or interlat Even if the change occurs, the communication between the mobile communication terminal device 70 and the server can be maintained after the handover or the interlat.

  FIG. 12 shows a block configuration of a test system 101 according to another embodiment of the present invention. The test system 101 differs from the test system 100 of the embodiment of the present invention shown in FIG. 1 in that the address resolution device 30 of the test system 100 is replaced with a pseudo base station device (# 0) 30a having an address resolution function. The point is different.

  The pseudo base station apparatus (# 0) 30a simulates a base station on an actual network, like each of the plurality of pseudo base station apparatuses 50 of the test system 100 according to the embodiment of the present invention shown in FIG. And address resolution at the time of communication between the communication facing device 20 and the pseudo base station devices 51 and 52, as in the address resolution device 30 of the test system 100 of the embodiment of the present invention shown in FIG. It also has a function to perform.

  However, when the pseudo base station apparatus (# 0) 30a does not function as the pseudo base station apparatus but only functions as the address resolution apparatus, the pseudo base station apparatus (# 1) 51 or the pseudo base station apparatus ( # 2) 52 has the same configuration as the test system 100 that functions as a pseudo base station apparatus.

  On the other hand, when the communication of the mobile communication terminal apparatus 70 is switched from the pseudo base station apparatus 51 or 52 to the pseudo base station apparatus (# 0) 30a due to a handover or the like, the communication passes through the relay apparatus 40. Instead, it is directly connected to the communication facing device 20.

  The test system 101 according to another embodiment of the present invention includes a pseudo base station apparatus (# 0) 30a having an address resolution function, but instead, an address resolution apparatus having the function of a pseudo base station apparatus. You may prepare.

  According to the test system 101 according to another embodiment of the present invention, even when a communication system with a different pseudo base station apparatus is added, the ARP table 30t and the address management table 40t are not changed. The test system can be configured simply by incorporating the function of the pseudo base station device into the address resolution device. For example, the pseudo base station apparatus 51 is W-CDMA, the pseudo base station apparatus 52 is GSM (registered trademark), and the pseudo base station apparatus (# 0) 30a is LTE. To do.
