Description

[0001] The present invention relates to a method and apparatus for setting a direction of a mobile communication antenna,

The present invention relates to a mobile communication antenna direction setting method and apparatus, and more particularly, to a mobile communication antenna direction setting method capable of intuitively setting an antenna installation direction when designing a cell coverage in a mobile communication network, .

An antenna is a component that converts electric signals and electromagnetic signals. The antenna converts radio signals of the public into electric signals, or transmits electric signals in the base stations or mobile devices to the public by broadcasting them in a radio frequency band.

Antennas for use in a mobile communication system can be broadly divided into omnidirectional antennas (Omni Directional Antenna) and directional antennas (Sector Antenna).

 Omnidirectional antennas are mainly used in suburban small cities with low traffic volume, connected roads and open terrain. On the other hand, directional antennas are mainly used in areas where traffic volume is concentrated and coverage is narrow due to a large population flowing toward the center of the urban area.

An omnidirectional antenna is an omnidirectional antenna in which a horizontal beam pattern propagates in space at the same intensity over 360 omni-directional, but has a shorter reach distance and can cause interference with an adjacent cell. In addition, the energy of the same intensity can propagate to the mountainous terrain or fields where there is little activity of the user, and it can become a waste of resources.

Accordingly, when the amount of call generated per base station and the repeater increases, a sector directional antenna having a high gain is used as a directional beam pattern instead of an omnidirectional antenna installed initially.

Recently, according to the development of mobile communication technology, mobile communication antennas currently available have various sizes and shapes according to their purposes and purposes, and show different electrical characteristics and beam patterns according to their types.

Particularly, the mobile communication antenna is one of the key components for determining the call quality of the mobile communication service, and is very important in the cell coverage designing stage of the mobile communication network.

Especially, in the initial cell coverage design of the mobile communication network, the direction setting of the base station antenna is very important for maintaining the call quality and solving the shadow area.

Conventionally, however, the cell coverage design has been disadvantageous in that it is performed through a simulation operation without consideration of the terrain / object and current situation of the area.

Accordingly, when the antenna is installed according to the cell coverage design, the mobile communication service operator generally performs field testing separately using actual mobile terminals and simulation equipment.

However, excessive field testing requires a lot of cost and effort, and has to be repeated every time a new antenna is added or removed or its position is changed.

 In particular, the existing antenna point design method tends to depend on the experience of the operator, and there is a great difficulty in accurately designing the operator who has little experience.

Hereinafter, an antenna technology used in a mobile communication system for facilitating understanding of the present invention will be briefly described.

The performance and capacity of the system may be limited by radio channel characteristics such as co-channel interference signals and multipath fading, delay of signals, Doppler spreading, and shadowing occurring between cells or within a cell of a mobile communication system.

In order to overcome the above performance and capacity limitation phenomenon, recently, various power control techniques, channel coding techniques, RAKE reception techniques, diversity antenna technologies, cell sectoring techniques, frequency division techniques, Technology is being utilized.

In particular, smart antenna technology is attracting attention as a promising core technology for solving the problem of deterioration due to radio channel characteristics and capacity reduction due to interference from neighboring cells.

In general, a smart antenna uses two or more antennas at a transmitting end, and can actively use the channel information to increase the efficiency of the antenna, thereby increasing the gain and reducing interference within the cell.

In addition, the smart antenna technology provides a function of enhancing transmission / reception performance by allowing the base station to grasp the position of the user based on the uplink signal received from the mobile device and controlling the radio wave signal of the base station antenna to be transmitted to the user .

Smart antennas can be classified in various ways depending on the beam forming method. Here, the shape of the beam is determined according to the weight of each antenna. At this time, the weight can be calculated by estimating the channel between the BS and the MS.

Such radiation patterns may include an electric field pattern, a power pattern, a phase pattern, and the like, and electric field patterns are mainly used.

In general, a radiaton pattern plot may be a principal plane pattern diagram such as an E plane or an H plane in which an azimuth angle and an altitude angle are fixed and another angle is changed as shown in FIG. 2B.

Here, the E plane means a single name including an electric field vector and having a maximum radiation direction together, and the H plane means a single plane including a magnetic field vector and having a maximum radiation direction together.

Particularly, FIG. 2B shows radiation patterns in an antenna having a non-directional directivity characteristic three-dimensionally through a spherical coordinate system. Here, the pattern diagram includes a polar plot, a linear plot, a 3-dimensional plot, and the like.

When the radiation pattern is represented by a power pattern, the radiation pattern can be expressed by an angle (Angle) and a decibel (dB) on the horizontal axis and the vertical axis, respectively, as shown in FIG. Here, the decibel means the square of the voltage (electric field intensity).

As shown in FIG. 2A, each radiation pattern is represented by a lobe.

8 is a flowchart illustrating a method of setting a direction of a mobile communication antenna according to another embodiment of the present invention.

More specifically, FIG. 8 is a flowchart for explaining a method of controlling an antenna direction using antenna beam pattern information of an adjacent cell.

Referring to FIG. 8, the antenna direction setting apparatus 300 may acquire the antenna characteristic information (s) corresponding to the neighbor cell list by connecting to the antenna characteristic information providing server 340 (S810). As described above with reference to FIGS. 3 to 4, the antenna direction setting apparatus 300 according to the present invention can acquire a neighbor cell list from the BS information providing server 330.

The antenna direction setting apparatus 300 obtains adjacent cell antenna characteristic information corresponding to the neighbor cell list (S813).

Subsequently, the antenna direction setting apparatus 300 generates an adjacent cell antenna beam pattern using the adjacent cell antenna characteristic information (S815).

Thereafter, the antenna direction setting apparatus 300 can display the generated adjacent cell antenna beam pattern on the sight-pointing screen (S817).

The antenna direction setting apparatus 300 generates an antenna beam pattern using the antenna characteristic information of the antenna to be installed (S819).

Subsequently, the antenna direction setting apparatus 300 calculates a target point of the target using the adjacent cell antenna beam pattern generated in step 815 and the antenna characteristic information generated in step 819 (step S821).

The antenna direction setting apparatus 300 adjusts the direction of the antenna with the calculated target point (S823).

The antenna direction setting device 300 according to another embodiment of the present invention may further include a memory and may store in the memory a predetermined antenna characteristic information database mapped with antenna characteristic information for each product identification code. Therefore, the antenna direction setting apparatus 300 can extract the antenna characteristic information from the internal database without connecting to a separate server, and generate an antenna beam pattern for the antenna.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
