  Hereinafter, a debug control system according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the embodiment. In this figure, the wireless transmission / reception terminal control PC 100 is configured such that a plurality of wireless transmission / reception terminals 11 can be connected. When the wireless transmission / reception terminal 11 is of a PC card type, the wireless transmission / reception terminal control PC 100 is equipped with a plurality of PCMCIA slots and the like. The wireless transmission / reception terminal 11 communicates with the wireless base station 1 using the PPP protocol while being connected to the wireless transmission / reception terminal control PC 100. Further, a network management device (PDSN or the like) 2 is connected to the radio base station 1. The wireless base station 1, the network management device 2, and the wireless transmission / reception terminal control PC 100 are connected to the wireless base station terminal PC3 via a network such as a wired LAN / WAN, and are controlled by the wireless base station terminal PC3. Debugging processing of software or the like in the radio base station 1 is performed while operating the radio transmission / reception terminal 11.

  In such a configuration, an IP address is not allocated to the wireless transmission / reception terminal 11 before a communication line is connected between the wireless transmission / reception terminal 11 and the wireless base station 1 by the PPP protocol. Therefore, communication using the IP protocol cannot be performed between the wireless base station terminal PC3 and the wireless transmission / reception terminal 11. For this reason, in the debug control system shown in FIG. 1, each wireless transmission / reception terminal 11 can be assigned as a virtual IP address (an IP address different from the actual IP address by the PPP session) in the wireless transmission / reception terminal control PC 100. A plurality of IP addresses are held. Then, the wireless transmission / reception terminal control PC 100 allocates a virtual IP address to the wireless transmission / reception terminal 11 in response to a request from the wireless base station terminal PC3 so that the IP protocol can be used in the subsequent debug processing sequence.

  As a result, since a virtual IP address can be allocated to the wireless transmission / reception terminal 11 without connecting a PPP session between the wireless transmission / reception terminal 11 and the wireless base station 3, a series of processes required for debugging of the wireless base station can be performed. It can be performed using the IP protocol from the wireless base station terminal PC3. Further, compared to the conventional debugging method, the equipment, personnel, and time required for debugging the radio base station 1 can be greatly reduced.

  In the example shown in FIG. 1, an example in which there is one wireless transmission / reception terminal control PC 100 is shown, but there may be a plurality of wireless transmission / reception terminal control PCs 100. Further, the wireless transmission / reception terminal 11 may be a PC card type wireless transmission / reception terminal, or may be a normal independent wireless transmission / reception terminal, as long as it can communicate with the wireless transmission / reception terminal control PC 100. . Further, the wireless transmission / reception terminal control PC 100 and the wireless base station terminal PC3 can be integrated, and the system configuration can be further simplified.

  FIG. 2 is a diagram showing a configuration of the wireless transmission / reception terminal control PC 100 shown in FIG. In FIG. 2, a plurality of wireless transmission / reception terminals 11 are connected to the wireless transmission / reception terminal control PC 100 via a communication I / F 131. The wireless transmission / reception terminal control PC 100 includes a memory 110 and a control unit 120. In the memory 110, a virtual IP address group 111 assigned to each wireless transmission / reception terminal 11, and a virtual IP address / test content relation table 112, which is a table in which a virtual IP address and a debug type are associated, are recorded. The control unit 120 includes a virtual IP address assignment unit 121 and a test control unit 122. The virtual IP address allocating unit 121 refers to the virtual IP address / test content relation table 112 according to the content of the debug (test) request instructed from the radio base station terminal PC3, and the necessary virtual IP address (virtual IP address) And the extracted virtual IP address is assigned to the wireless transmitting / receiving terminal 11 and set. The test control unit 122 performs a test corresponding to the address range of the virtual IP address on the wireless transmission / reception terminal 11 in which the virtual IP address is set.

  Here, the virtual IP address / test content relationship table will be described with reference to FIG. FIG. 5 is a diagram showing an example of a virtual IP address / test content relationship table, in which a correspondence relationship between virtual IP addresses (virtual IP address ranges) assigned to 25 wireless transmission / reception terminals 11 and test content is recorded. is there. As shown in FIG. 5, when performing a software download test to the wireless transmission / reception terminal 11, virtual IP addresses “169.xxx.yyy.10” to “169.xxx.yyy.34” are assigned to the wireless transmission / reception terminal 11. It is done. When performing a downlink throughput test from the wireless base station 1 to the wireless transmission / reception terminal 11, virtual IP addresses “169.xxx.yyy.35” to “169.xxx.yyy.59” are assigned to the wireless transmission / reception terminal 11. Assigned. When an uplink throughput test from the wireless transmission / reception terminal 11 to the wireless base station 1 is performed, virtual IP addresses “169.xxx.yyy.60” to “169.xxx.yyy.84” are assigned to the wireless transmission / reception terminal 11. . Similarly, a virtual IP address for command control of the wireless transmission / reception terminal 11 and log acquisition of the wireless transmission / reception terminal 11 is assigned to the wireless transmission / reception terminal 11. In this manner, different virtual IP addresses are assigned to the wireless transmission / reception terminals 11 according to the test contents.

  Next, with reference to the sequence diagrams shown in FIGS. 3 and 4, the operation of controlling the wireless base station terminal PC3 to download the software for the wireless transmission / reception terminal and the throughput measurement operation that occur during debugging of the wireless base station 1 will be described. To do. In the following description, it is assumed that 25 wireless transmission / reception terminals 11 are installed. First, it is assumed that the wireless transmission / reception terminal control PC 100 holds a virtual IP address necessary for controlling the wireless transmission / reception terminal 11. In this example, the wireless transmission / reception terminal control PC 100 holds virtual IP addresses “192.xxx.yyy.10” to “192.xxx.yyy.109” as virtual IP address groups (step S1). . The wireless base station terminal PC3 transmits a “software download test request” to the wireless transmission / reception terminal 11 to the wireless transmission / reception terminal control PC 100 (step S2).

  When receiving the “software download test request” from the wireless base station terminal PC3, the wireless transmission / reception terminal control PC 100 receives the virtual IP address / test content in the memory 110 by the function of the virtual IP address assignment unit 121 (see FIG. 2). With reference to the relationship table 112 (see FIG. 5), a virtual IP address required for software download is obtained (step S3). In this case, the virtual IP addresses are “192.xxx.yyy.10” to “192.xxx.yyy.34”, and these IP addresses are allocated and set to the wireless transmission / reception terminal 11 (step S4).

  When the virtual IP address is assigned to the wireless transmission / reception terminal 11, the wireless transmission / reception terminal control PC 100 performs software download by the function of the test control unit 122 (step S5). This software download is performed using the virtual IP address assigned to the wireless transmission / reception terminal 11 (step S6). The software to be downloaded is stored in advance in the wireless transmission / reception terminal control PC 100. When software download to the wireless transmission / reception terminal 11 is performed, a “wireless transmission / reception terminal software download test response” is transmitted from the wireless transmission / reception terminal control PC 100 to the wireless base station terminal PC3 (step S7). Upon receiving the “wireless transmission / reception terminal software download test response” from the wireless transmission / reception terminal control PC 100, the wireless base station terminal PC3 transmits a “throughput measurement request” to the wireless transmission / reception terminal control PC 100 (step S8).

  In response to the “throughput measurement request” from the wireless base station terminal PC3, the wireless transmission / reception terminal control PC 100 uses the function of the virtual IP address assignment unit 121 (see FIG. 2) to relate the virtual IP address / test content in the memory 110. Referring to the table (see FIG. 5), a virtual IP address necessary for the “throughput measurement request” is obtained (step S9). In this case, the virtual IP addresses are “192.xxx.yyy.35” to “192.xxx.yyy.59”, and these IP addresses are allocated and set to the wireless transmission / reception terminal 11 (step S10).

  Next, in the wireless transmission / reception terminal control PC 100, the test control unit 122 performs throughput measurement (step S11). For this purpose, the wireless transmission / reception terminal control PC 100 transmits a “PPP session connection request to the wireless base station” to the wireless transmission / reception terminal 11 using the virtual IP address (step S12). In response to the “PPP session connection request” from the wireless transmission / reception terminal control PC 100, the wireless transmission / reception terminal 11 executes a PPP connection sequence (wireless) with the wireless base station 1 (step S13). When a PPP session is connected between the wireless transmission / reception terminal 11 and the wireless base station 1, data is transmitted / received using an IP address assigned by the PPP protocol (step S14). Further, the wireless base station 1 executes PPP protocol processing (step S15).

  When data transmission / reception is performed between the wireless transmission / reception terminal 11 and the wireless base station 1 by the PPP protocol, a “throughput measurement response” is transmitted from the wireless transmission / reception terminal control PC 100 to the wireless base station terminal PC3 (step S16). When receiving the “throughput measurement response” from the wireless transmission / reception terminal control PC 100, the wireless base station terminal PC3 transmits a “wireless transmission / reception terminal log acquisition request” to the wireless transmission / reception terminal control PC 100 (step S17).

  In response to the “wireless transmission / reception terminal log acquisition request” from the wireless base station terminal PC3, the wireless transmission / reception terminal control PC 100 uses the function of the virtual IP address assignment unit 121 (see FIG. 2) to With reference to the test content relation table 112 (see FIG. 5), a virtual IP address necessary for the “log acquisition request” is obtained (step S18). In this case, the virtual IP addresses are “192.xxx.yyy.85” to “192.xxx.yyy.109”, and these IP addresses are allocated and set to the wireless transmission / reception terminal 11 (step S19).

  After setting the virtual IP address in the wireless transmission / reception terminal 11, the wireless transmission / reception terminal control PC 100 executes log acquisition from the wireless transmission / reception terminal 11 by the test control unit 122 (step S20). Then, the wireless transmission / reception terminal control PC 100 acquires a wireless transmission / reception terminal log from the wireless transmission / reception terminal 11 (step S21), and transmits a “wireless transmission / reception terminal log acquisition response” to the wireless base station terminal PC3 (step S22). In the radio base station terminal PC3, a radio transmission / reception terminal log is obtained from the radio transmission / reception terminal control PC 100, and a radio base station log is obtained from the radio base station 1 (step S23).

  In this way, by making a difference in test contents for each wireless transmission / reception terminal based on the virtual IP address, a series of processing required for debugging of the wireless base station 1 is performed using the IP protocol according to an instruction from the wireless base station terminal PC3. And can be done efficiently. In addition, compared to the conventional debugging method, the equipment, personnel, and work time required for debugging the radio base station 1 can be greatly reduced.

  In the sequence diagrams shown in FIG. 3 and FIG. 4, an example of “throughput measurement” is shown as the test content. However, another virtual IP address is set, for example, after setting the PPP session, the allocated virtual Various tests by simultaneous control of the radio base station / radio transmission / reception terminal are performed, such as a power control processing confirmation test of the radio base station 1 while changing the transmission power of the radio transmission / reception terminal 11 based on the IP address. It may be.

In this example, the same virtual IP address is assigned to all 25 terminals and the same debugging process is performed. However, when different debugging processes are required for each terminal, virtual IPs corresponding to different debugging processes are used. An address may be assigned to each terminal that performs the debugging process, and different debugging processes may be performed almost simultaneously.
For example, “192.xxx.yyy.35” to “192.xxx.yyy.44” are allocated to 10 of 25 terminals, and downlink throughput measurement is performed on another 10 terminals, and “192.xxx.yyy. 60 ”to“ 192.xxx.yyy.69 ”is allocated to perform uplink throughput measurement, and“ 192.xxx.yyy.85 ”to“ 192.xxx.yyy.89 ”is allocated to the remaining five units to obtain logs. You may make it perform. In this case, the radio base station terminal PC3 sequentially performs “downlink throughput measurement”, “uplink throughput measurement”, and “log acquisition” requests to the radio transmission / reception terminal control PC 100 with a slight time lag, and each debugging process performs each radio transmission / reception. This is performed as simultaneous parallel processing between the terminal 11 and the radio base station 1, and the radio base station terminal PC3 sequentially receives the results of the debug process (throughput measurement response, log acquisition response).

  Further, the above-described wireless base station terminal PC3 and wireless transmission / reception terminal control PC100 have a computer system therein. A series of processes related to the above-described process is stored in a computer-readable recording medium in the form of a program, and the above-described process is performed by the computer reading and executing this program. That is, each processing in the wireless base station terminal PC3 and the wireless transmission / reception terminal control PC 100 is performed by a central processing unit such as a CPU reading the above program into a main storage device such as a ROM or RAM to process information and perform processing. It is realized by executing.

  Here, the computer-readable recording medium means a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like. Alternatively, the computer program may be distributed to the computer via a communication line, and the computer that has received the distribution may execute the program.

  Although the embodiment of the present invention has been described above, the debug control system of the present invention is not limited to the above illustrated example, and various modifications can be made without departing from the scope of the present invention. Of course.

  Since the present invention has the effect of greatly reducing the equipment, personnel, and work time required for debugging a computer device to be debugged such as a radio base station, the present invention is useful for a debug control system and the like.
