Mode for Carrying Out the Invention

[0012] Hereinafter, the present disclosure will be described through embodiments, but the disclosure according to the claims is not limited to the following embodiments. Also, not all of the configurations described in the embodiments are necessarily essential as means for solving the problems. In each drawing, the same elements are denoted by the same reference numerals, and duplicate explanations are omitted as necessary.

[0013] <Embodiment 1> Hereinafter, Embodiment 1 of the present disclosure will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an information processing apparatus according to Embodiment 1. The information processing apparatus 10 according to Embodiment 1 includes a generation unit 11 and an output unit 12.

[0014] The generation unit 11 determines one cell among a plurality of cells managed by a radio base station as a reference cell. Here, among the plurality of cells managed by the radio base station, a cell other than the reference cell is referred to as a non-reference cell. A log associated with the reference cell is referred to as a reference log, and a log associated with a non-reference cell is referred to as a non-reference log. The generation unit 11 generates a corrected log obtained by deleting information identical to the information included in the reference log from the information included in the non-reference log. Here, among the information included in the non-reference log, the information identical to the information included in the reference log is referred to as deletion information. Also, the length of the deleted information is referred to as the deletion data length.

[0015] The information included in the corrected log will be described while referring to FIG. 2. FIG. 2 is a diagram showing the information included in the log associated with cell #a and the information included in the log associated with cell #b according to Embodiment 1. The information A, B, and C in FIG. 2 represent parameters composed of at least one or more pieces of information. In FIG. 2, the reference cell is cell #a. In any case, the information identical to the information included in cell #a and the information included in cell #b is "AB". In other words, the deletion information is "AB", and the information included in the corrected log is "C".

[0016] Referring to Figure 2, we will explain the information indicating the location of deletion in the deleted information. In cases 1 and 2, where the deleted information "AB" is a concatenated sequence, the beginning of "AB" is the starting point n1, and the end of "AB" is the position n2. In this case, the deleted data length L1 is the length of "AB". On the other hand, in the case where the deleted information "AB" is not in a concatenated sequence as in Case 3, the beginning of "A" becomes the starting point n1, and the end of "A" becomes position n2. In this case, the deleted data length L1 is the length of "A". Also, the beginning of "B" becomes the starting point n3, and the end of "B" becomes position n4. The deleted data length L3 is the length of "B".

[0017] The output unit 12 outputs the reference log, the modified log, and information indicating the location of the deleted information. The output unit 12 may, for example, output the reference log, the modified log, and information indicating the location of the deleted information to a display. Alternatively, the output unit 12 may transmit the reference log, the modified log, and information indicating the location of the deleted information to another terminal device.

[0018] Next, the log acquisition method according to Embodiment 1 will be described. Figure 3 is a flowchart showing the flow of the log acquisition method according to Embodiment 1. First, the generation unit 11 designates one cell as the reference cell from among the multiple cells managed by the wireless base station (ST1). Next, the generation unit 11 generates a modified log by deleting information from the non-reference log that is identical to the information included in the reference log (ST2). Next, the output unit 12 outputs the reference log designated by the generation unit 11, the modified log generated by the generation unit 11, and information indicating the location of the deleted information (ST3).

[0019] As described above, the information processing device 10 according to Embodiment 1 outputs information that is identical to the information contained in the log associated with multiple cells managed by the wireless base station. Therefore, the amount of information contained in the log and the information transfer time can be reduced. As a result, even if the number of cells managed by the wireless base station increases, the amount of information contained in the increasing log can be suppressed, enabling efficient log acquisition processing.

[0020] <Embodiment 2> Embodiment 2 of this disclosure will now be described with reference to the drawings. Figure 4 is a block diagram showing the configuration of the information processing device 20 according to Embodiment 2. The information processing device 20 according to Embodiment 2 includes a classification unit 23, a generation unit 21, and an output unit 22. The following assumes that a wireless base station manages multiple cells.

[0021] The classification unit 23 classifies multiple cells into multiple cell groups based on their communication type. The communication type can be, for example, the wireless access method, transmission / reception method, frequency bandwidth, or vendor type. Examples of wireless access methods include LTE (Long Term Evolution) and NR (New Radio). Examples of transmission / reception methods include TDD (Time Division Duplex) and FDD (Frequency Division Duplex). Multiple cells may be classified into at least two or more cell groups. The classification unit 23 classifies the multiple cells into cell groups based on a pre-configured communication type.

[0022] The generation unit 21 designates one cell as the reference cell from among multiple cells belonging to the same cell group. A reference cell is designated for each cell group. Here, among multiple cells belonging to the same cell group, cells other than the reference cell are referred to as non-reference cells. The log associated with the reference cell is referred to as the reference log, and the log associated with the non-reference cell is referred to as the non-reference log. The generation unit 21 generates a modified log by deleting information from the non-standard log that is identical to information included in the standard log. The modified log is generated for each cell group. Here, information from the non-standard log that is identical to information included in the standard log is referred to as deleted information. The length of the deleted information is referred to as the deleted data length.

[0023] If the information contained in the reference log differs from the information contained in the non-reference log, the generation unit 21 generates a corrected log by deleting the information in the non-reference log that is identical to the information contained in the reference log.

[0024] On the other hand, the generation unit 21 does not generate a corrected log if the information included in the reference log includes all the information included in the non-reference log.

[0025] The output unit 22 outputs, for each cell group, a reference log defined by the generation unit 21, a modified log generated by the generation unit 21, and information indicating the location of deletion of the deleted information. For example, the output unit 22 may output the reference log, the modified log, and the information indicating the location of deletion of the deleted information to a display. Alternatively, the output unit 22 may transmit the reference log, the modified log, and the information indicating the location of deletion of the deleted information to another terminal device.

[0026] The information indicating the location of deletion is shown using the starting point of the information identical to the information included in the standard log in the non-standard log, and the length of the deleted information.

[0027] Furthermore, the information indicating the location of deletion may be shown using the start and end points of the same information included in the standard log in the non-standard log.

[0028] The output unit 22 may output a standard log defined by the generation unit 21, a modified log generated by the generation unit 21, and information indicating the location of deletion in the deleted information, according to the user's request. The user can change the requested content for each cell group. For example, the output unit 22 may output a standard log defined by the generation unit 21 and a modified log generated by the generation unit 21, corresponding to the command input for the content to be investigated during operation verification.

[0029] The following describes the log acquisition process in the information processing device 20, using the case of five cells as an example. The wireless access methods for each of the multiple cells are assumed to be: Cell #1 = LTE, Cell #2 = NR, Cell #3 = LTE, Cell #4 = NR, Cell #5 = NR.

[0030] The classification unit 23 classifies cells #1 to #5 into cell groups based on a pre-configured communication type. Here, the pre-configured communication type is the wireless access method. Based on the wireless access method, the classification unit 23 classifies cells #1 and #3 into cell group A, and cells #2, #4, and #5 into cell group B.

[0031] Next, the generation unit 21 will be described with reference to Figures 5 and 6. Figure 5 shows the information contained in the logs associated with cells #1 and #3 according to Embodiment 2. Figure 6 shows the information contained in the logs associated with cells #2, #4, and #5 according to Embodiment 2. The information shown in Figures 5 and 6 represents the parameter name and parameter value, which are general components of log information. The log information in the same row in the cells shown in Figures 5 and 6 shows parameters that represent the same type of information. Parameters that represent the same type of information are, for example, cell identification information and base station information. Here, we define cell #1 as the reference cell in cell group A, and cell #2 as the reference cell in cell group B.

[0032] First, the modified log in cell group A will be explained with reference to Figure 5. The generation unit 21 compares the same rows in the logs associated with cell #1 and cell #3. The difference in the information contained in the logs of cell #1 and cell #3 is that cell #1 contains "parameter 2-1 (defg)", while cell #3 contains "parameter 2-1 (OPQR)". In other words, the modified log becomes "OPQR".

[0033] Next, referring to Figure 5, we will explain the information indicating the location of deletion in cell group A. Here, the deletion information is contained in cell #3, which is an out-of-standard log. The starting point n1 (#3) of the deletion information contained in cell 3 may be indicated using the address representing the beginning of "Parameter 1" in cell #3. The ending point n2 (#3) of the deletion information contained in cell 3 may be indicated using the address representing the end of "Parameter 2-1 ()" in cell #3. In this case, the deletion data length L1 is the length of "Parameter 1 (abc), Parameter 2 (Parameter 2-1 ()". The starting point n3(#3) of the deletion information contained in cell 3 may be indicated using the address representing the beginning of "), parameter 2-2" in cell #3. Similarly, the ending point n4(#3) of the deletion information contained in cell 3 may be indicated using the address representing "parameter n(xyz)" in cell #3. In this case, the deletion data length L2 will be the length of "), parameter 2-2(hij)), parameter 3(klmn)···parameter n(xyz)".

[0034] Next, referring to Figure 6, we will explain the modified logs in cell group B. The reference cell in cell group B is cell #2. We compare the information contained in the logs associated with cell #2 and cell #4, and with cell #2 and cell #5. In this case, as with cell group A, the comparison of the information contained in the logs associated with the cells is done by comparing the information in the logs associated with cell #2, cell #4, and cell #5 that are in the same row. The difference in the log information between cell #2 and cell #4 is that cell #2 shows "Parameter 2-1(α)", while cell #4 shows "Parameter 2-1(αβ)". On the other hand, the difference in the log information between cell #2 and cell #5 is that cell #2 shows "Parameter 2-1(α)", while cell #5 shows "Parameter 2-1(αβγ)". In other words, the corrected logs will be "β" and "βγ".

[0035] Next, referring to Figure 6, we will explain the information indicating the location of deletion in cell group B. Here, deletion information is included in cells #4 and #5, which are non-standard logs. The starting point n1 of the deletion information contained in cell #4 may be indicated using the address representing the beginning of "Parameter 1" in cell #4. Similarly, the ending point n2 of the deletion information contained in cell #4 may be indicated using the address representing the end of "Parameter 2-1(α)" in cell #4. In this case, the deletion data length L1 will be the length of "Parameter 1(123), Parameter 2(Parameter 2-1(α))". The starting point n3 of the deletion information contained in cell #4 may be indicated using the address representing the beginning of "))" in cell #4. Similarly, the ending point n4 of the deletion information contained in cell #4 may be indicated using the address representing the end of "parameter n(xxx)" in cell #4. In this case, the deletion data length L2 will be the length of ")), parameter 3(456), ... parameter n(xxx)". On the other hand, the starting point n1 of the deletion information contained in cell #5 may be indicated using the address representing the beginning of "Parameter 1" in cell #5. Also, the ending point n2 of the deletion information contained in cell #5 may be indicated using the address representing the end of "Parameter 2-1(α)" in cell #5. In this case, the deletion data length L1 will be the length of "Parameter 1(123), Parameter 2(Parameter 2-1(α))". The starting point n3 of the deletion information contained in cell #5 may be indicated using the address representing the beginning of "))" in cell #5. Similarly, the ending point n4 of the deletion information contained in cell #5 may be indicated using the address representing the end of "parameter n(xxx)" in cell #5. In this case, the deletion data length L2 will be the length of ")), parameter 3(456), ... parameter n(xxx)".

[0036] The output unit 22 outputs the reference log for cell group A and cell group B, the modified log, and information indicating the location of deletion in the deleted information. In this case, the information indicating the location of deletion is shown using the starting point of the deletion information and the length of the deleted data. Alternatively, the information indicating the location of deletion may be shown using the starting and ending points of the deletion information.

[0037] In other words, the output unit 22 outputs the information contained in the log associated with cell #1 as the reference log, "OPQR" as the modified log, and the start point and deletion data length of the deleted information in cell #3 as the start point and deletion data length of the deleted information. Alternatively, the output unit 22 outputs the information contained in the log associated with cell #1 as the reference log, "OPQR" as the modified log, and the start and end points of the deleted information in cell #3 as the start and end points of the deleted information. Furthermore, the output unit 22 outputs the information contained in the log associated with cell #2 as the reference log, "β" and "βγ" as the modified log, and the start point and deletion data length of the deleted information in cell #4 and cell #5 as the start point and deletion data length of the deleted information. Alternatively, the output unit 22 outputs the information contained in the log associated with cell #2 as the reference log, "β" and "βγ" as the modified log, and the start point and end point of the deleted information in cell #4 and cell #5 as the start point and end point of the deleted information.

[0038] Next, the log acquisition method according to Embodiment 2 will be described. Figure 7 is a flowchart showing the flow of the log acquisition method according to Embodiment 2. First, the classification unit 23 classifies multiple cells into cell groups based on the communication type (ST01). Next, the generation unit 21 designates one cell from among multiple cells belonging to the same cell group as the reference cell for each cell group (ST02). Next, the generation unit 21 generates a modified log for each cell group by deleting the same information included in the reference log from the information included in the non-reference log (ST03). Subsequently, the output unit 22 outputs the reference log generated by the generation unit 21, the modified log, and information indicating the location of the deleted information for each cell group (ST04).

[0039] As described above, the information processing device 20 according to Embodiment 2 classifies multiple cells managed by a wireless base station based on their communication type. It then deletes duplicate information from the logs associated with cells belonging to the same classification and outputs the result. This reduces the amount of information contained in the logs and the information transfer time. As a result, even if the number of cells managed by the wireless base station increases, the amount of information contained in the increasing logs can be suppressed, enabling efficient log acquisition processing.

[0040] <Embodiment 3> Embodiment 3 of this disclosure will now be described with reference to the drawings. Figure 8 is a block diagram of the information processing system 100 according to Embodiment 3. The information processing system 100 according to Embodiment 3 includes an information processing device 30 and a receiving device 40.

[0041] The information processing device 30 includes a classification unit 33, a generation unit 31, and an output unit 32. The classification unit 33, generation unit 31, and transmission unit 32 are the same as the classification unit 23, generation unit 21, and output unit 22 in Embodiment 2, so their description is omitted. Furthermore, the information processing device 30 does not necessarily have to have a classification unit 33. In this case, the generation unit 31 and the transmission unit 32 are the same as the generation unit 11 and output unit 12 according to Embodiment 1, respectively.

[0042] The receiving device 40 has a receiving unit 41 and a restoration unit 42. The receiving device 40 does not necessarily have to have a restoration unit 42.

[0043] The receiving unit 41 receives the reference log output by the information processing device 30, the modified log, and information indicating the location of deletion of information identical to the information contained in the reference log in the non-reference log. The transmission and reception method may be wired or wireless. The wireless network includes, for example, a wireless communication network using a communication line standard such as LTE. The wireless network may also include a wireless LAN (Local Area Network) or a wireless communication network such as a fifth-generation mobile communication system.

[0044] The restoration unit 42 restores the non-standard log by combining information from the non-standard log that is identical to the information in the standard log, based on the information indicating the deletion location, with the information contained in the modified log. For example, in cell #3 shown in Figure 5, the restoration unit 42 restores cell #3 by combining the deleted information with the modified log "OPQR" based on the information indicating the deletion location, namely start point n1, end point n2, start point n3, and end point n4. Alternatively, the restoration unit 42 restores cell #3 by combining the deleted information with the modified log "OPQR" based on the information indicating the deletion location, namely start point n1, start point n3, deleted data length L1, and deleted data length L2.

[0045] As described above, the information processing system 100 according to Embodiment 3 deletes identical information from the information contained in the log associated with multiple cells managed by the wireless base station and outputs it. The information processing system 100 according to Embodiment 3 restores the deleted information and the start and end points of the deleted information. As a result, the amount of information contained in the log and the information transfer time can be reduced, and the receiving side can restore the information and perform operational verification.
