Description

This disclosure relates to an information processing device, an information processing system, a log acquisition method, and a log acquisition program. In recent years, communication technologies related to fifth-generation mobile communication systems (5G) have been developed. 5G radio waves have characteristics such as high directivity and a tendency to easily drop out. Therefore, operational verification is essential to achieve stable network operation. To address this, it has been proposed to collect logs for operational verification in wireless base station equipment systems and use these logs to detect anomalies. For example, Patent Document 1 discloses an information processing device that acquires and manages log information associated with information to be processed. Japanese Patent Publication No. 2018-097602 This is a block diagram showing the configuration of the information processing device according to Embodiment 1.This figure shows the information contained in the log associated with cell #a and the information contained in the log associated with cell #b according to Embodiment 1.This is a flowchart showing the flow of the log acquisition method according to Embodiment 1.This is a block diagram showing the configuration of the information processing device 20 according to Embodiment 2.This is information contained in the logs associated with cells #1 and #3 according to Embodiment 2.This is information contained in the logs associated with cells #2, #4, and #5 according to Embodiment 2.This is a flowchart showing the flow of the log acquisition method according to Embodiment 2.This is a block diagram of the information processing system 100 according to Embodiment 3. The disclosure will be described below through embodiments, but the disclosures in the claims are not limited to the embodiments described below. Furthermore, not all of the configurations described in the embodiments are necessarily essential for solving the problem. In each drawing, the same elements are denoted by the same reference numerals, and redundant explanations are omitted where necessary. <Embodiment 1> Embodiment 1 of this disclosure will now be described with reference to the drawings. Figure 1 is a block diagram showing the configuration of an information processing device according to Embodiment 1. The information processing device 10 according to Embodiment 1 has a generation unit 11 and an output unit 12. The generation unit 11 designates one cell from among the multiple cells managed by the wireless base station as the reference cell. Here, cells other than the reference cell among the multiple cells managed by the wireless base station are referred to as non-reference cells. Logs associated with the reference cell are referred to as reference logs, and logs associated with non-reference cells are referred to as non-reference logs. The generation unit 11 generates a modified log by deleting information from the non-standard log that is identical to information included in the standard log. 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. Referring to Figure 2, the information contained in the modified log will be explained. Figure 2 shows the information contained in the log associated with cell #a and the information contained in the log associated with cell #b according to Embodiment 1. In Figure 2, information A, B, and C represent parameters consisting of at least one piece of information. In Figure 2, cell #a is the reference cell. In both cases, the identical information contained in cell #a and cell #b is "AB". In other words, the deleted information is "AB", and the information contained in the modified log is "C". 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" becomes the starting point n1, and the end of "AB" becomes 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". The output unit 12 outputs the reference log, the modified log, and information indicating the location of the deleted information. For example, the output unit 12 may 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 l
