Description

Telemonitoring intergrated system of local central office

The present invention relates to a remote monitoring integrated system of the central office. More specifically, the present invention relates to a remote surveillance integrated system that can remotely execute monitoring and control of an environment such as an unmanned central station.

Due to the development of information and communication technology, change of life style and growth of economy, the form of communication culture is changing rapidly, and in the information age, the demand for high-speed information transmission is regardless of time and place. Mobile communication, which can receive communication services in and mountainous areas, is becoming an important communication medium indispensable in daily life.

Unlike the wide area method, which uses a service area as one large area, a mobile communication system divides an entire service area into a small service area called a cell and allocates a certain number of radio channels available within each cell. do.

In addition, the wireless base stations (Cell Sites) installed in each cell are centrally controlled in the switching system, and the repeater receives and amplifies the low output radio signals transmitted from the wireless base station and the terminal for smooth communication between the base station and the user terminal. The RF signal is transmitted to the terminal and the base station.

Such a mobile communication system is capable of remote monitoring function by the unmanned work of each central office.

At this time, an IP of 192.168.240.1 is assigned to the NMS network of the surveillance camera.

As described above, in constructing a general regional centered remote monitoring system, central offices are arranged in each region, and these central offices are integrated again into ITC offices as a single management network through a TCP / IP network.

Since the central offices installed in each unit area are generally operated as unmanned central offices where operators do not reside, there is a need for a system that can remotely monitor and control the transmission status and environmental conditions in the central offices.

However, as described above, if the NMS equipment and IP address of the central station are used, the compatibility between the IP 60.21.xx band of the NMS network and the surveillance camera NMS network IP 192.xxx band may be inconsistent. do.

In addition, NMS / surveillance camera networks were separated for each transmission room, resulting in an increase in transmission line cost and a weak remote monitoring and maintenance system.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a central station that can stably operate a transmission network by operating monitoring and real-time performance analysis by integrating and operating an NMS network and a central station monitoring camera NMS network.
