Description
The present invention generally relates to a mobile communication system. More particularly, the present invention relates to an antenna device for a Base Station (BS) in a mobile communication system.
In a mobile communication system, a BS (including a Relay Station (RS)) typically collects data from Mobile Stations (MSs) via their connections and transmits the collected data to a switching network. The BS amplifies a transmission signal through a high-power amplifier within a BS body, transmits the amplified signal to an antenna device, and radiates it through the antenna device. The antenna device receives a signal from an MS and transmits the received signal to the BS body, for processing. For the purpose of providing a service, the antenna device is installed at a high place such as a building rooftop or a tower and the base station is installed on the ground within a building or under a tower.
As stated above, the antenna device is installed in an elevated position to maximize the propagation distance of a radio signal. In an urban area, typically, a post is put up on the rooftop of a building, a fixture is mounted onto the post, and a communication antenna is installed to the fixture.
Although the antenna device for the mobile communication system should be installed at an appropriate position to enable reliable wireless communications, such a site is hard to secure because the antenna device is considered as an obstacle to a living environment and thus building owners typically do not want antenna equipment installed. Therefore, it is difficult to find an installation site for the antenna device.

Accordingly, there are too many unnecessary and disfiguring posts in downtown or urban environments.
An aspect of exemplary embodiments of the present invention is to address at least the problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of exemplary embodiments of the present invention is to provide an antenna device for a mobile communication system, which can be installed in a place where an existing street lamp or a surveillance camera is installed in order to facilitate securing of an installation site.

A further aspect of exemplary embodiments of the present invention provides an antenna device for a mobile communication system to reduce the number of posts used for module installation by enabling installation of a lamp module for a street lamp, a surveillance camera module, and various sensor modules to one post.
Still another aspect of exemplary embodiments of the present invention provides an antenna device for a mobile communication BS, which looks good or at least looks familiar in order to be harmonized with the ambient environment.
In accordance with an aspect of exemplary embodiments of the present invention, there is provided an antenna device for a mobile communication system, in which a post or pole having the external appearance of a conventional sign, lamp, or utility pole has an antenna end for housing and receiving antenna parts, and a support end for fixing the post or pole to the ground.

The control module 130 further includes a signal processor 136 for processing signals transmitted and received between the interface 132 and antenna elements 114 and a controller 138 for providing overall control to the antenna device 10' including the camera module 30 and the lighting module 20.
The control module 130 includes the sensor module 40 with sensors for rendering the operational control of the camera module 30 and the lighting module 20 under the controller 138 more accurate. For example, the sensor module 40 may include an illumination or luminance sensor or a motion sensor. Therefore, the controller 138 can control illumination and/or brightness of the lighting module 20 based on brightness information received through the illumination sensor and can control the lighting module 20 to be less bright based on information received through the motion sensor, when there is no moving object like a person or a vehicle. Also, the controller 138 may enable image capture by the camera module 30, for example only when a moving object is sensed through the motion sensor.
To be more specific about the camera module 30, data captured by a surveillance camera is usually transmitted to a separately constituted local server via a dedicated line. The local server temporarily stores captured data received from a plurality of surveillance cameras, individually, and transmits the captured data to a central server over a communication network such as a dedicated network or the Internet. The central server preserves and manages the captured data.
According to the present invention, data captured by the camera module 30 may be transmitted to a Base Station Controller (BSC) via a communication line basically established between a BS and the BSC, without passing through a separately procured dedicated line. The BSC may preserve and manage the captured data or transmit the captured data to a central server designed for preservation and management of the captured data over a communication network, such as a dedicated network or the Internet. Data captured by each camera module 30 has an Identifier (ID) of a camera that has captured the data, so that the captured data may be stored on a camera basis.
The central server stores the captured data of each camera received from the BS through the BSC, and searches for and displays the captured data of a specific camera according to a manipulation of an operator. The operator or a subscriber that is pre-registered to receive a service may remotely access the central server through a terminal (not shown) and receive the captured data search and display service from the central server.
As is apparent from the above description, the antenna device for a mobile communication system according to the present invention is shaped into a post on the whole and includes a support end to be fixed on the ground and an antenna installation end for installing antenna parts. Therefore, because a light for a street lamp or a surveillance camera can be installed on the post, the antenna device may substitute for a conventional street lamp and surveillance camera. As a result, an installation site for the antenna device may be more readily secured.
Also, there is no need to secure a new site for installing a wireless BS and the difficulty in finding a site, which is expensive in an urban area with a large number of mobile calls, is avoided.
The replacement of a conventional street lamp and surveillance camera with the antenna device facilitates securing power and connection to an existing communication cable.
Because the post of the antennadevice is shaped like a familiar street lamp or utility pole, the antenna device may feel familiar and in harmony with the ambient environment.
The mobile communication antenna devices according to the exemplary embodiments of the present invention may be configured and operated as described above. While the above description has been made of specific exemplary embodiments, many modifications can be made within the scope of the present invention. For example, while the external enclosure of the antenna end 11 and the support end 12 has a cylinder-like shape, it is clear that it may take the shape of a rectangular prism or an octagonal prism.
Also, the sensor module may include various sensors, such as a temperature-humidity sensor, in addition to the illumination or luminance sensor or the mobility object sensor and the antenna device may transmit information sensed by these sensors, for use in a variety of services.
The antenna device may transmit data captured by the camera module or other sensor modules in real time. Or the antenna device may include an inner memory, temporarily store the captured data in the inner memory, and transmit the captured data every appropriate period (or at an appropriate timing).
The antenna device may transmit the data captured by the camera module or other sensor modules in the same manner as a mobile communication signal is usually transmitted, by using the camera module as a terminal of a mobile communication network. That is, a phone number is pre-assigned to the camera module, for identification, and a phone number is also pre-assigned to the central server, so that a video communication channel may be established between the camera module and the central server over a communication network. Herein, the central server may be provided in a BS or a BSC in a typical mobile communication system. In this case, the data captured by the camera module may be transmitted in the early morning in which a smaller number of calls are conducted over the mobile communication network.
While the invention has been shown and described with reference to certain exemplary embodiments of the present invention thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents.
