Unified mobile repeater system {UNIFIED REPEATER SYSTEM FOR MOBILE COMMUNICATION SERVICE}

The present invention relates to an integrated mobile communication repeater system, and more particularly, to provide an integrated service of subscriber signals of various frequency bands each serviced by a plurality of mobile communication service providers using one common base station and a common repeater. An integrated mobile communication repeater system is provided.

In the conventional mobile communication repeater system, many base stations that can transmit and receive signals to and from subscribers of other communication networks through the switching center are densely installed in the urban area, and the base stations are connected to each other by an optical cable to enable communication between the base stations.

The base station services a subscriber station located within its service area directly through an antenna.

A terminal subscriber in one base station's service area can connect with another terminal subscriber in the service area of another base station, but cannot access if the other mobile terminal or his mobile terminal is out of the base station's service area. do.

It is necessary to install as many base stations as possible in order to remove the service area limitation in the mobile communication network, but repeaters are installed in mountain areas or island areas where the use efficiency is low compared to the base station installation cost.

However, such a conventional mobile communication repeater system has various mobile communication service providers such as three PCS companies, three to four IMT-2000 companies, and two cellular companies in various places such as ground, subway, tunnel, etc. Or by installing a repeater, there was a problem that a lot of facility costs and operating costs.

In addition, such a conventional mobile communication repeater system has a problem in that communication interruption is increased due to mutual signal interference caused by a base station or a repeater which is closely installed in an urban area, and due to the increase in communication breakdown, the amount of installation of a base station or repeater is limited. There was a problem with receiving.

In other words, because there are many users of mobile phones and high-rise buildings, more base stations should be constructed than other places, and many mobile communication service providers distribute their own base stations, which requires not only a large installation cost and space, but also interference with each other. There was a problem that a communication interruption sound occurs by.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to integrate subscriber signals of various frequency bands serviced by a plurality of mobile communication service providers using a common base station and a common repeater. It is to provide an integrated mobile communication repeater system that allows.

In order to achieve the above objects, the present invention synthesizes the forward subscriber signals received from a plurality of mobile communication service provider switching stations for each relay area and transmits them to the corresponding relay area, and transmits the reverse subscriber signals received from the plurality of relay areas. An integrated base station for distributing by mobile telecommunication service provider and transmitting to the telecommunication service provider switching center; Distributing forward subscriber signals received from the integrated base station for each mobile communication service provider and transmitting them to the subscriber station of the corresponding mobile communication service provider, synthesizing the reverse subscriber signals received from the subscriber stations of a plurality of mobile communication service providers.
