(Base Station Controller: BSC), Base Station Manager system (BSM) that manages and manages various base station controllers (Mobile Switching Center: MSC) and location registration system.

The area serviced by each base station is called a cell, and is generally divided into three sectors. This cell expands to the base station area, base station controller area, and switching center service area in order.

As described above, a communication system using one cell as a unit is called a cellular system.

A mobile station in each cell establishes a channel and performs communication with a base station serving that cell. In this case, a channel formed in the direction of the mobile station from the base station is called a forward channel, and a channel formed in the direction of the base station from the mobile station is called a reverse channel.

The forward channel includes a pilot channel, an optionally included sync channel, also an optional paging channel, and several forward traffic channels.

The reverse channel includes an access channel and a reverse traffic channel.

The mobile station and the base station exchange voice information and data using the traffic channel.

In a mobile communication system, systems below the switching center system are commonly referred to as a base station subsystem (BSS), which is composed of a base station management system, a base station controller system, and a base station system in a higher order.

The main processor of the base station controller system is called a Call Control Processor (hereinafter referred to as CCP), and the main processor of the base station system is called a BTS Control Processor (hereinafter referred to as BCP). do.

In the conventional mobile telephone or personal base station system configured as described above, only an outdoor installation module such as an antenna is installed outside the roof of a building, and all other equipment is installed and operated with a separate indoor bureau.

This separate installation of a national office causes a number of problems such as an increase in user fees, difficulty in securing a national office due to an increase in the number of base stations, and an increase in maintenance costs for controlling and monitoring environmental conditions inside the office.

The base station system selects and installs the most suitable location for the operation of the mobile communication system.

This process is called a cell plan. If a base station is installed at a location determined by the cell plan, another building selection is required to install a station at that location.

Even if the location of the national office is secured, a flexible cabling process between the indoor system and the outdoor antenna is required, and the time required from shipment to installation is not only required for equipment manufacturers but also service providers. It will result in loss.

This process involves many difficulties in actually installing the base station at the cell location determined by the cell plan.

Therefore, the present invention was devised to solve the above problems, and has an air conditioner such as an air conditioner, a heat exchanger, a fan, and a heater so as to perform functions such as rain and external environment / external access control. An object of the present invention is to provide an outdoor base station for a mobile communication system capable of remotely managing by installing a monitor or manager for environmental monitoring.

The present invention devised to achieve the above object,

A base station internal system; An outer enclosure for eliminating the possibility of thermal insulation and destruction of the internal system by inserting insulation into a double wall structure made of aluminum using a urethane foam sealing method; An environmental control device connected to the enclosure and configured to determine whether to operate the heater or the heat exchanger according to a temperature change inside / outside the system; It is linked with the internal system of the base station and comprises an environmental monitoring device for reporting the failure of the environmental control device to the upper operating system through the sensor and performing repairs for the failure.

The base station installed outdoors should have all the functions of the indoor base station used in the related art, and further have a function for coping with external environmental factors.

Therefore, the outdoor base station according to the present invention has the following configuration to cope with external environmental factors.

1. enclosure

The enclosure for an outdoor base station according to the present invention is rainproof based on the international standard IP-55, and for this purpose, a sealing method using urethane foam was used.

In order to minimize the influence of the external environment, the double wall structure is adopted and the walls are insulated. This double wall structure protects the system from the risk of intrusion or destruction due to its unique outdoor installation.

By manufacturing the exterior walls with aluminum, the weight of the base station itself is reduced and the possibility of corrosion due to outdoor installation is eliminated.

By constructing the enclosure as described above, the system is completely blocked inside and outside the mounted enclosure, and protects the system from the penetration of moisture, dust, salt, and the like.

In addition, the connection to the outside of the base station system must be connected using a waterproof connector.

2. environmental control device

In order to cope with the high temperature phenomenon caused by the heat generation of the system in the summer and the low temperature phenomenon in the winter season, there is a heater and a heat exchanger which are completely blocked inside and outside.

Through such a structure, the system can operate normally in a heat and low temperature environment.

3. environmental monitoring device

According to the outdoor installation of the base station, a system environment control device of the base station is required. In addition, a management device or a monitoring device to detect and report an environmental control device in case of a failure may be installed.

The outdoor base station mounted in the enclosure has the same function and performance as the indoor base station. In order to seal with the outside air, a double seal is provided. For the normal operation of the sealed inner system, an environmental control device capable of performing heat and low temperature control is attached to the outside of the enclosure.

For the monitoring of the internal environment, a monitor / manager is installed inside the system, and related sensors that can detect temperature, humidity, fire, and flooding are attached.

The monitoring and management device is linked with the system to enable the monitoring and control remotely from the system of the base station operating unit.
