Description

Base station sector antenna control device and its operation method {A OPERATING METHOD AND A CONTROL DEVICE OF SECTOR ANTENNA FOR BTS}

The present invention relates to varying a service area by a sector antenna of a mobile communication base station system, and more particularly, to a control device and a method of controlling the beam pattern and directing characteristics for resolving traffic imbalance and traffic distribution between service areas of a sector antenna. It is about.

In a wireless communication system such as a cellular mobile communication system and a wireless subscriber network (WLL), a signal is transmitted and received by wirelessly connecting to a mobile terminal or a mobile terminal through an antenna of the base station.

The base station of the mobile communication system is wirelessly connected to a plurality of mobile terminals through an antenna, and the antenna is largely divided into an omni antenna and a sector antenna according to a purpose.

The omni antenna is a wide area in all directions as a service area, and is used when the number of mobile terminals is relatively small in the service area, and the sector antenna transmits and receives a radio signal only in a predetermined direction, thereby providing a beam pattern. ) It is to communicate with the mobile terminal in a specific area based on the characteristics, direction characteristics or direction characteristics.

A sector antenna having the above-mentioned directivity is generally used in combination of two or three, and four or more various combinations are also used depending on the purpose and environment.

In the base station of the mobile communication system, a sector antenna is mainly used in consideration of various reasons such as spatial ubiquity and frequency recycling of a call generated from a mobile terminal.

The base station sector antenna may use two or three sector antennas or one or four or more antennas in consideration of traffic loads between two to three sectors (SECTOR). It is assumed that the traffic load by the call occurring in the area is constant.

Hereinafter, a sector antenna operating method according to the related art will be described with reference to the accompanying drawings.

1 is a diagram illustrating a sector antenna system operating method according to the prior art.

Referring to FIG. 1, the mobile communication base station system 30 operating a sector antenna according to the related art includes an antenna having a fixed directivity characteristic and a constant service area or coverage. By way of example, a sector antenna 10 combining three directional or directional antennas each having an α sector 12 region, a β sector 14 region, and a γ sector 16 region,

It is composed of a plurality of portable terminals 20 located in each service area and communicating with the sector antenna 10 by wireless communication.

In the sector antenna of the base station system according to the related art having the above-described configuration, for example, three service areas 12, 14, and 16 formed by the sector antenna 10 are fixed, and the mobile terminal in each service area is fixed. It is assumed that traffic by call CALL generated by 20 is constant.

As shown in the right figure of FIG. 1, for example, a plurality of mobile terminals 20 are biased in the α sector 12, and a plurality of calls are generated, thereby increasing the traffic density and increasing the β sector ( 14) and the gamma sector 16 have a small number of mobile terminals 20, and a call does not occur and there is no traffic density.

In this case, for example, a user having the mobile terminal 20 in the α sector 12 region is crowded temporarily or periodically or congested due to traffic congestion. The sector 16 area is not.

As described above, the α sector 12 region is not always high in traffic density due to a large number of calls, and is a phenomenon that occurs temporarily when there is a commute time or an event. It is a reality that a communication line cannot be fixedly assigned, and the beta sector 14 area and beta sector 16 area are areas in which a constant arc occurs on average.

In the case of the region such as the α sector 12 according to the above example, when traffic is concentrated, communication is difficult due to a limited communication channel, and the β sector 14 region and the gamma sector 16 region are relatively traffic. Low density leaves room for communication channels.

Even if the channel allocated to the base station is sufficient, communication cannot be performed because the channel is temporarily or momentarily short for each sector.

That is, the sector antenna 10 of the base station system 30 has a fixed beam pattern (BEAM PATTERN) and directivity characteristics. When traffic is concentrated in a specific sector, the beam pattern and the directivity of the sector antenna must be adjusted by mechanical work. Therefore, there is a problem in that it is not possible to quickly respond to a momentary or temporary traffic change.

Therefore, the conventional sector antenna as described above has such a sector that when the traffic load generated in each sector is not constant, i.e., regardless of the total channel capacity allocated to the base station, a large traffic load occurs in a particular sector. There is a problem in that the communication area cannot communicate more than the fixed allocated channel capacity.

Therefore, there is a problem that the traffic load that is acceptable for each sector, that is, the channel capacity is fixed and limited, does not adequately cope with temporal and spatial traffic changes.

Hereinafter, the present invention having the above-described configuration, the base station sector antenna control apparatus and its operation method will be described with reference to FIGS.

In the mobile communication system, the base station system 160 according to the present invention includes a sector antenna 100, a base station 110, a detector 120, an antenna controller 130, and a passive controller 140. 110 is wired to the switching center 150 and is connected to the plurality of mobile terminals 20 wirelessly through the sector antenna (100).

As described above, the number of sector antennas 100 varies depending on the surrounding environment of the installation place. In general, two or three sector antennas are installed, and four or more sector antennas may be installed.

The reason for using the sector antenna 100 as described above is to increase utilization efficiency by recycling limited frequency resources, and may use different frequencies or the same frequency for each sector antenna unit 100, Even in the same area, there may be a large number of CALL connections in a certain space due to spatial division, and there is no call connection in an adjacent space, and the situation may change from time to time. One that can be easily managed is a directional or directional sector antenna (ANTENNA) 100.

The sector antenna 100 may be divided into an α sector antenna 102, a β sector antenna 104, and a gamma sector antenna 106 based on respective directing characteristics, for example, when three are used.

The base station 110 connected to the sector antenna 100 applies a call (CALL) received from the mobile terminal 20 to the switching center 150, the corresponding call signal (CALL) applied from the switching station 150 is When the wireless terminal 20 transmits wirelessly to the mobile terminal 20 through the sector antenna 100 and the mobile terminal 20 does not receive a signal transmitted from the sector antenna 100 well, the level of output power (POWER) By increasing LEVEL and transmitting TX, the frequency and the modulation / demodulation method to be transmitted / received are used in the same manner as the portable terminal 20.

The detection unit 120 detects the output power level transmitted (TX) from the base station 110 through the respective sector antennas 102, 104, and 106, and is connected through the respective sector antennas 102, 104, and 106 (CALL). Detects the traffic density by the number of and applies it to the antenna controller 130.

The antenna controller 130 is input from the detector 120 and transmits the traffic density by the call (CALL) connected through the sector antennas 102, 104, and 106 from the base station 110 through the sector antennas 102, 104, and 106. The output power level is analyzed to determine how much difference there is between adjacent sector antennas 102, 104, and 106, and whether the difference is greater than or equal to a predetermined level.

The antenna controller 130 determines as described above and controls the beam pattern and the directivity of the sector antenna 100 in a corresponding manner according to whether the set operation mode is a traffic mode, a time mode, or a manual mode. MONITORING

Each of the sector antennas 102, 104, and 106 has a small control motor for controlling the beam pattern, and a small control motor for controlling the directivity of the sector antennas 102, 104, and 106, respectively. The beam pattern is variably controlled by the corresponding control signal applied, and the directivity characteristic is variably controlled.

As described above, the antenna controller 130 for controlling the beam pattern and the directivity characteristic of the sector antennas 102, 104, and 106 is operated in the traffic mode and the time mode by using built-in and input programs and data, and in the manual mode. The manual control unit 140 variably controls the beam pattern and the directivity of the sector antennas 102, 104, and 106 by control data manually input by the operator.

The operation method using the base station sector antenna control apparatus of the present invention as described above will be described with reference to FIG. 4. The operation mode currently set in the antenna controller 130 is a traffic mode or a mode. It is determined whether the time mode (TIME MODE) or manual mode (MANUAL MODE) (S100).

In the traffic mode determined as described above, the traffic density and the level of the output power transmitted by the call (CALL) connection of each sector antenna (102, 104, 106) of each sector antenna (102, 104, 106) from the base station 110 through the detection unit 120, respectively (S110). In operation S120, the difference value is calculated as an absolute value by comparing the traffic density of the detected sector antennas 102, 104, and 106 with the level of the output power.

Since the difference value calculated above has a magnitude according to a sign by the calculation method, the absolute value is used.

It is determined whether the difference value calculated as described above is equal to or greater than the predetermined value (S130). If the determination result is equal to or less than the predetermined value, the current beam pattern and directivity of the corresponding sector antennas 102, 104, and 106 are maintained. Returning to step S100 (S140), if the predetermined value is greater than or equal to the predetermined value, it is determined whether the traffic density value and the output power level of the corresponding sector antennas 102, 104, 106 are higher or lower than those of the adjacent sector antennas 102, 104, 106. (S150).

If the determination result (S150) is high, the mode process after reducing the width formed by the beam pattern of the current sector antenna (102, 104, 106) to a predetermined size and controlling or adjusting the direction by the directivity characteristic in a predetermined direction, It returns to S100 (S160).

In addition, when the traffic density and the output power level of the current sector antennas 102, 104, and 106 are lower than those of the adjacent sector antennas 102, 104, and 106 as determined in the traffic determination process (S150), the beam pattern width of the current sector antennas (102, 104, and 106) is determined. After increasing the control to adjust the directivity in the set direction, and returns to the mode process (S170).

If it is determined in the mode process (S100) that the time mode is determined, the operator sets a time zone to control periodically input or correction input (S180), and when the input is completed, the process proceeds to the next input process (S190). .

The control time zone, which is input as described above, may be divided into one unit, one day unit, one week unit, one month unit, one season unit, and one year unit, and determined by repetitive experiments and statistics. Fixed event schedule is reflected.

The input process S190 inputs or modifies corresponding data values for controlling or adjusting beam patterns and directivity of the sector antennas 102, 104, and 106 for each control time zone, and when the input is completed, the next sequence of time. Proceed to the determination process (S200).

If it is determined in the time determination process (S200) and is set to periodically control each sector antenna (102, 104, 106) and the input control time has not reached, it returns to the mode process (S100), and the corresponding control time If this has been reached, the beam pattern and the directivity of each sector are adjusted according to the adjustment data inputted for each sector antenna 102, 104, and 106, and then fed back to the mode process S100 (S210).

Judging in the mode process (S100), when the manual mode for controlling the beam pattern and the directivity characteristic of each sector antenna (102, 104, 106) manually from the manual control unit 140 is set, the antenna controller 130 is near or remotely After controlling or adjusting the beam pattern and the directivity of the sector antennas 102, 104, and 106 according to the data input from the connected manual controller 140, the controller returns to the mode process S100 (S220).

The manual mode as described above is applied, for example, when there is a large-scale event in a specific area or needs to be directly controlled by an emergency event.

In summary, the antenna controller 130 determines whether the set mode is a traffic mode, a time mode, or a passive mode, and in the case of the traffic mode, the sector antennas 102, 104, and 106 from the base station 110 through the detector 120. Detects and compares the traffic density and the transmit output power level of the signal, and if it is smaller than the value of the adjacent sector antennas 102, 104, 106, increases the beam pattern width to a predetermined size and adjusts the directivity in the set direction. If it is larger than the values of the adjacent sector antennas 102, 104 and 106, the beam pattern width is reduced to a predetermined size and the directivity is adjusted in the set direction. When the above process is repeated, precise control is performed.

In the case of the time mode, a time zone and control data for periodically controlling the beam pattern and directivity of the sector antenna are input or modified, and when the control time zone is set as described above, the corresponding sector antenna ( Adjust or control the beam pattern and directivity characteristics of 102, 104 and 106.

In case of the manual mode, the beam pattern and the directivity or direction characteristic of each sector antenna 102, 104, 106 are controlled by control data inputted directly by the operator through the manual control unit 140 installed remotely or locally. Control or adjust.

Referring again to the accompanying Figure 3, shown in (a) is designed to attempt a call connection from a certain number of mobile terminals 20 in the service area of each sector antenna (102, 104, 106), as designed above It shows the case of operating ideally,

Sector antenna 102. FIG. When a CALL connection is attempted from 20, i.e., when the traffic density is high and the level of the transmitted output power is high, the?

Make sure that is assigned regularly.

As shown in (b) of FIG. 3, in another example, when the traffic density increases on the β sector antenna 104, the traffic load is applied to each sector antenna 102, 104, 106 by reducing the beam pattern width and adjusting the directivity. Shows the state controlled to be added constantly,

The sector antenna as described above may be applied to two or three or four or more as an example, and may be variously applied depending on the surrounding environment.

There is an industrial use effect to provide call quality.

In addition, it provides the optimal channel environment and call quality with limited frequency resources against periodic or temporary call connection changes, and effectively distributes traffic between sector antennas, thereby reducing the load on the system and improving reliability.
