[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centralized maintenance system for an entire mobile communication system including a base station of a mobile radio, a wireless switching device, and a wired switching device.

[0002]

Conventional mobile communication systems, as shown in FIG. 5, the replacement mobile radio to the exchange processing of calls of the plurality of base stations BS ₁₁ to BS _1n and the base station controller BCE not shown mobile radio It is composed of devices MSC ₁ to MSC _m , a wireless monitoring and control device OMC, a wired monitoring and control device CMOC, and the like. The base station BS ₁₁ to BS _1n mobile radios, because they are many installed in a wide area, it is necessary to perform the necessary control to grasp the individual states of which such effectively. It is also necessary to monitor and control the mobile wireless switching devices MSC ₁ to MSC _m simultaneously with other devices. In conventional mobile communication systems, the switching monitoring and control unit CMOC and the wireless monitoring and control unit OMC are installed separately, and monitoring information for the switching system is collected in the CMOC and monitoring information for the wireless system is collected in the OMC. Is done. The necessary control is the same as the monitoring, and the switching system is CMO
From C, the radio system was operated by OMC, and the operation was separated from each other.

[0003]

Therefore, the following problems have occurred in the conventional maintenance system of the mobile communication system. Since the monitoring and control unit CMOC for the switching system and the monitoring and control unit OMC for the wireless system were installed separately, the monitoring and control of the switching system and the wireless system were performed separately, and the wireless base station BS ₁₁
~ BS _1n to switching devices MSC ₁ -MSC _m cannot be centrally managed as one mobile communication system.
Monitoring and control unit CMOC for switching system and OMC for monitoring and control unit for wireless system
Are composed of different devices, so that both operation and maintenance require a person in charge of a wireless system and a person in charge of a wired system, thus increasing the operation cost. An object of the present invention is to enable a single mobile communication system to manage from a wireless base station BS to a mobile wireless switching device MSC as a single mobile communication system. An object of the present invention is to provide a centralized maintenance method for a mobile communication system, which is low.

[0004]

According to the basic structure of the present invention for achieving this object, as shown in the principle diagram of FIG. 1, a monitoring and control unit (CMC) for a wireless system is replaced with a monitoring and control unit (CMOC) for a switching system. Into a single centralized monitoring and control device MOC, and this single centralized monitoring and control device MOC monitors all devices constituting the system. At this time, the mobile radio switching device MSC includes a protocol conversion unit 1 for performing protocol conversion necessary for interfacing with a wired system (for example, conversion from X.25 to NO.7 and vice versa). The protocol conversion of the monitoring information of the wireless system to the wired system of the lower layer is performed, and the switching information is transmitted from the mobile wireless switching device MSC to the centralized monitoring and control device MOC. Also, as with the monitoring information, the control information is controlled by one centralized monitoring and control device MOC.
Distributing process to which mobile radio switching equipment MSC to send
After performing (2 ₁ ), the mobile radio switching device MSC performs a distribution process (2 ₂ ) to which radio base station BS to send to and a conversion (1) to a lower layer radio system protocol. The control information from the centralized monitoring and control device MOC is transmitted to the required radio base station BS.

[0005]

According to the present invention, a conventional wireless monitoring and control device (OM

Send to MOC. Explaining with reference to the explanatory diagram of the protocol conversion unit in FIG. 2, when receiving, for example, three pieces of monitoring information 1, 2, and 3 from a certain radio base station BS, the mobile radio switching apparatus MSC transmits the radio signal of the lower layer. The system protocol is converted into a wired protocol, and the own monitoring information N is sent to the centralized monitoring and control device MOC in addition to the information. As for the control information, similarly to the monitoring information, the centralized monitoring and control device MOC performs a distribution process (2 ₁ ) to which mobile radio switching device MSC to send, and in the mobile radio switching device MSC, After performing the distribution process (2 ₂ ) and the lower layer protocol conversion (1) as to whether or not to send to the wireless base station BS, the centralized monitoring controller MOC
To the required radio base station BS. Therefore, the centralized maintenance system of the mobile communication system according to the present invention allows the centralized monitoring and control device MOC to centrally manage the radio base station BS to the switching device MSC as one mobile communication system and operate it. Only one person is required for maintenance, and operation costs are reduced.
