  • Patent number: 8073011
    Abstract: Provided is a pseudo base station apparatus which allow a user to certainly acquire log data at a desired timing. A set-up unit 41 sets filter conditions and acquisition conditions. A first log acquisition unit 32A includes a first buffer 32Aa, which stores log data and updates the stored content when the buffer capacity is full, and acquires a first log data that a user wants. A second log acquisition unit 32B includes a detector 32Ba, which detects log data that coincides with the log acquisition conditions among the log data, and a second buffer 32Bb, which stores the log data detected by the detector 32Ba and constantly updates the stored content within the range of the buffer capacity, and acquires a second log data that a user wants.
