The O & M is a subsystem used for base station maintenance.

However, when confirming the base station information using the WSM, it is difficult for the user to check the information of the base station in the development process because the user can use the WSM in the state of the system loading is completed. In addition, the WSM is inconvenient to check the access to the WSM server in order to monitor the information of the base station from a remote location. In other words, the user can monitor the base station only when the base station knows the registered WSM server information.

Therefore, there is a need for an apparatus and method that can easily diagnose a base station at a remote location.

Similarly, the DMI 410 is connected to one DM 400 and is connected to several DMs 400, 401, and 402. This means that when there are several base station diagnosis apparatuses, several base station diagnosis apparatuses can diagnose one base station at the same time.

5 is a flowchart illustrating a connection, maintenance, and release of a DM and a DMI in a base station diagnostic system according to an exemplary embodiment of the present invention.

Referring to FIG. 5, first, the DM 500 transmits a DM connection request message (DM_CONNECT_REQUEST) to the DMI 520 in step 501 to connect the DM 500 and the DMI 520. Here, the DMI 520 receiving the DM connection request message performs a DM registration 509 to communicate with the DM 500. In step 502, the DMI 520 transmits a DM connection response message (DM_CONNECT_RESPONSE) to the DM 500. As a result, the DM 500 prepares for diagnosing information of the base station, and the DMI 520 prepares to provide information required for diagnosing the base station when the DM 500 requests.

After the DM 500 is connected to the DMI 520, the DM 500 periodically transmits a DM echo request message (DM_ECHO_REQUEST) to the DMI 520 in step 503. Upon receiving the DM echo request message, the DMI 520 transmits a DM echo response message (DM DM_ECHO_RESPONSE) to the DM 500 confirming that the connection is established. As a result, the DM 500 may periodically check the connection establishment problem.

Here, in FIG. 6, the DM and the DMI connections 501 and 502 of FIG. 5 are the same, and thus detailed description thereof will be omitted.

Referring to FIG. 6, after the DM 600 is connected to the DMI 620, the DM 600 sends a DM log start request message (DM_LOG_START_REQUEST) for requesting necessary information in step 603. To send. For example, the information may include a system parameter, an automatic gain control parameter (AGC parameter), a hardware random number generator (RNG) information, channel quality indicator (CQI) information, and ACK (ACKnowledge) information. The information may be scheduling information, traffic information, beamforming information, frame information, and the like.

In step 604, the DMI 620 receiving the DM log start request message transmits a DM log start request message to the modem 630 to collect the information in the base station. Thereafter, the DMI 620 transmits a response message (DM_LOG_START_RESPONSE: hereinafter referred to as a "DM log start response message") to the DM 600 in response to the DM log start request message.

Thereafter, the DMI 620 drives the timer 611 to read log data of the corresponding information from the module at a predetermined interval for a predetermined time period through the modem 630. Thereafter, the DMI 620 transmits the log data read in steps 606 and 607 to the DM 600 through an IP interface in the form of a DM log message (DM_LOG_DATA).

Thereafter, when the DM 600 desires to confirm the desired information, the DM 600 transmits a DM log stop request message (DM_LOG_STOP_REQUEST) related to the information to the DMI 600 in step 608. Upon receiving the DM log stop request message, the DMI 600 stops 612 the timer in operation and issues a stop command to the corresponding module in the base station through the modem 630.

Thereafter, the DMI 620 transmits a response message (DM_LOG_STOP_RESPONSE: hereinafter referred to as "DM log stop response message") to the DM 600 in response to the DM log stop request message.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the mobile communication system uses the DM to perform remote diagnosis of the DMI in the base station through the Internet communication, so that the base station is not needed to reboot the base station, and only the DM application application is installed on a computer connected to the Internet. Information of the desired base station can be conveniently checked in a graphical environment.

In addition, since a single DM can monitor multiple base station information at the same time, since the DMI operates independently of the base station, there is an advantage that it can be monitored without affecting the operation of the base station.
