The present invention relates to a relay device having a variable distribution function, and more particularly, to a variable distribution function that integrally configures a variable distribution device for varying and distributing a signal for each floor of a building and an antenna for transmitting and receiving the signal. It relates to a relay device.

In general, a mobile communication system manages a plurality of base station transceiver systems, a base station controller, and a plurality of base station controllers to communicate with a mobile terminal (mobile station) located within a corresponding service area to provide a service. Base Station Manager System, Mobile Switching Center, etc. Such a mobile communication system generally covers the call coverage area by appropriate arrangement of each base station, but a call shadow area, such as the underground space of a large building or the inside of a high-rise building, which has a significant decrease in call quality may occur. . Therefore, the mobile communication system amplifies the signal received from the base station and transmits the signal received from the base station to the mobile terminal (not shown) in the shaded area to prevent the degradation of the communication service due to the shaded area formed in the basement or building. The relay device 10 for amplifying a signal received from the base station and transmitting the signal to the base station is installed and operated in the shaded area.

1 is a view showing the overall installation structure and state showing a mobile communication network relay device 10 used in a general in-building system.

First, as shown in Figure 1, the installation structure of the relay device, the relay device 10 is installed at an appropriate position (for example, the top of the building) in the building 20 to cover the shadow area inside the building 20 And a master unit 11 for drawing an RF signal from a base station (not shown) via wire or wirelessly.

The master unit 11 receives a signal input through a transmission line (wired cable) 15 to connect to a plurality of distribution devices 12 that can be installed in each floor of the building 20. 12) is distributed and connected. The distribution device 12 is connected by an antenna 14 and a transmission line 15 provided on each floor in the building 20.

The distribution device 12 provides a service by communicating with a mobile terminal (not shown) located in the service area using the floor installed in the building 20 as a service area.

The master unit 11 and the distribution device 12 are connected via a transmission line (wired cable) 15 to transmit a signal, and the signal is distributed by the distribution device 12 through the transmission line 15. It is connected to the antenna 14 to provide a service.

Since the relay devices 10 widely used in in-building and the like can cover the shadow area relatively economically, it is expected that a large amount of small repeaters will be used in the next generation mobile communication system IMT-2000.

In particular, as the proportion of data-oriented services increases in voice-oriented services, the role of the relay device in the in-building system is not merely to secure a range of services, but to accommodate subscriber capacity and to serve as a spot cell. Its importance is growing.

2 is an enlarged view of a relay device used in an in-building system of a commonly used building.

The signal is transmitted to the distribution device 12 connected through the master unit 11 and the transmission line 15, and the signal transmitted to the distribution device 12 is distributed by the plurality of distribution devices 12.

The distribution device 12 is provided with a plurality of connecting connectors 16 for connecting with the master unit 11.

The signal entering the distribution device 12 is determined by the distance between the main transmission line 13 and the couple line 13 'while the signal flows through the main transmission line 13.

The signal distributed by the first distribution device 12 communicates with a terminal (not shown) in the service area of the radiating element 14 connected with the distribution device 12. After the primary distribution, the signal from the master unit 11 is further connected to the distribution device 12 via a further connected transmission line 15.

The connected dispensing device 12 operates like the first dispensing device 12, and then the other dispensing device 12 likewise acts like the first dispensing device 12.

However, in order to make the intensity of the received signal of each floor the same, the distribution amounts of the respective distribution devices 12 must be set differently. According to the floor of the building distributed and serviced in the first distribution device 12, the first distributed signal is lost in the transmission line between them in order to share the received signal of the floor serving through the distribution device 12. And in consideration of the intensity of the distributed signal, the distribution of the second distribution device 12 is greater than that of the first distribution device 12 to make the received signals of each layer the same.

However, the mobile communication network installed in the existing building of the building must use distribution devices of different sizes on each floor in order to have the same size of service signal on each floor. Installation time is required for installation because it needs to be connected by using transmission line and connecting connector.

In addition, since the distribution device and the antenna must use separate transmission lines and connection connectors to connect with each other, manufacturing costs increase.

Accordingly, an object of the present invention is to provide a variable distribution device for varying and distributing a signal for each floor of a building and an antenna for transmitting / receiving the signal. It is to provide a relay device having a variable distribution function.

Another object of the present invention is to configure a variable distribution device for varying signals and a slave unit having an antenna built therein, thereby eliminating the need for a transmission line and a connection connector for connecting an existing antenna, thereby reducing a manufacturing cost of a product.
