Description

Method and device for implementing sector configuration in a communication system

technical field

The invention relates to the technical field of network communication, in particular to a method and device for realizing sector configuration in a communication system.

Background technique

In the mobile communication system, it is necessary to distinguish the mobile communication users so that the mobile communication users do not affect each other.

There are many ways to distinguish mobile communication users, and the carrier frequency, that is, the frequency of electromagnetic wave propagation, and geographical area are the two main ways to distinguish. That is to say, different mobile communication users are located in different geographical areas, or use different carrier frequencies, then the system can distinguish these different mobile communication users, and the mutual influence between mobile communication users is very small, which can meet the needs of mobile communication. user requirements.

Therefore, in the communication system, in order to increase the system capacity and support more mobile communication users communicating with the communication system at the same time, increasing the number of sectors and increasing the number of carriers are two commonly used methods.

A sector is to divide a circular area into multiple fan-shaped areas. In a mobile communication system, there are three typical sector division methods, as shown in Figure 1. (a) in Figure 1 is an omnidirectional distribution diagram, that is, a sector area; (b) is the distribution map of three sectors; (c) is the distribution map of six sectors.

When planning and designing a communication system, a base station is generally set up in a certain geographical area, and the base station can be planned as an m×n communication system, where m represents the number of sectors, and n represents the number of carriers in each sector. For example, when planning and designing the WCDMA (Wideband Code Division Multiple Access) system in a region, if it is planned to be a 3×4 system, it means that the region is divided into 3 sectors, and each sector has 4 carriers; If a 6×2 system is planned, it means that the area is divided into 6 sectors, and each sector has 2 carriers.

There is a one-to-one correspondence between sectors and antennas, and antennas are used to receive and transmit wireless signals. Different carriers in the same sector use the same antenna.

The logical block diagram of the base station equipment configured in 3×4 is shown in FIG. 2 .

In FIG. 2, the base station equipment has three sectors, and each sector has four carriers. Sector 1 is taken as an example below to introduce the working principle of the base station equipment.

The transmission process of sector 1: the transmitting module 101-1 outputs the first carrier signal of sector 1, the transmitting module 101-2 outputs the second carrier signal of sector 1, and the transmitting module 101-3 outputs the first carrier signal of sector 1. 3 carrier signals, the transmitting module 101-4 outputs the fourth carrier signal of sector 1, the four carrier signals of sector 1 are combined into one signal by the combining module 103 of sector 1 and output to the power amplifier of sector 1 105. The power amplifier 105 amplifies the signal, and outputs the amplified signal to the duplexer 106 of sector 1, and then outputs the amplified signal to the antenna 107 of sector 1 from the duplexer 106, and finally radiates out from the antenna.

The receiving process of sector 1: the antenna 107 of sector 1 outputs a signal that combines the received four carrier signals to the duplexer 106 of sector 1, and the duplexer 106 outputs the signal to the A branching module 104, the branching module 104 divides the signal into four carrier signals, and simultaneously transmits the four carrier signals to the four receiving modules 102-1, 102-2, 102-3 and 102- 4. The receiving module (102-1) processes the first received carrier signal of sector 1, the receiving module (102-2) processes the second received carrier signal of sector 1, and the receiving module (102-3) processes the sector The third received carrier signal of sector 1, and the receiving module (102-4) processes the fourth received carrier signal of sector 1.

The working principle of sector 2 and sector 3 in FIG. 2 is the same as that of sector 1 .

It can be seen from the above description that the duplexer is mainly used to separate the transmitted signals and received signals with different frequencies, and the antenna is used for both transmitting signals and receiving signals.

The logical block diagram of the base station equipment configured in 6×2 is shown in FIG. 3 .

In FIG. 3 , the base station equipment has six sectors, and each sector has two carriers. The working principle of each sector of the base station equipment is the same as that of sector 1 of the base station equipment in a 3×4 configuration.

By comparing the base station equipment with different configurations above, it can be seen that the base station equipment with 3×4 configuration and the base station equipment with 6×2 configuration use the same number of transmitting modules and receiving modules, and there are 12 transmitting modules and receiving modules each. , due to the different sector configurations, the signal combining methods are different.

Usually, we collectively refer to 3×1 configuration, 3×2 configuration, 3×3 configuration and 3×4 configuration as three-sector configuration, because they have one thing in common, that is, three antennas are used, corresponding to three sectors. The number of carrier frequencies in each sector is different. If there are several carrier frequencies, several transmitting modules and several receiving modules are used. Similarly, the 6×1 configuration and the 6×2 configuration are collectively referred to as a six-sector configuration.

During system design, considering the diversity of sector configurations, it is generally required that base station equipment can support either three-sector configurations or six-sector configurations. The base station equipment implements different configurations through different connection methods. In addition, considering the operability, it is better to have as few changes as possible when the base station equipment supports different configurations, and the simpler the operation, the better. In order to better understand how the base station equipment supports different sector configurations, we take sector 1 in FIG. 2 as an example to specifically illustrate how the base station equipment supports three-sector configurations and six-sector configurations. The relationship between the three-sector configuration and the six-sector configuration in part of the system connection changes is shown in Figure 4. We can illustrate the system connection change between the base station equipment supporting the three-sector configuration and the six-sector configuration according to FIG. 4 .

In Fig. 4, the left half is a connection diagram of three-sector configuration, and the right half is a connection diagram of six-sector configuration. 108 in the figure is a removable jumper, that is to say, connect it when needed, and take it away when not needed. It can be seen from Figure 4 that the form and quantity of the modules on the left and right sides are exactly the same, but the connection methods of the jumpers are different.

(1) When three sectors are configured, the working principle of the base station equipment is as follows:

The transmission process of sector 1: the transmitting module 101-1 outputs the first carrier signal, the transmitting module 101-2 outputs the second carrier signal, and the first carrier signal and the second carrier signal are combined through the combining module 103 output and enter the first input port of the combiner module 103-1. The transmitting module 101-3 outputs the third carrier signal, and the transmitting module 101-4 outputs the fourth carrier signal. The third carrier signal and the fourth carrier signal are combined and output through the combining module 203, and then passed through the jumper 108 Enter the second input port of the combiner module 103-1, the combiner module 103-1 combines the two input signals to output the combined signal of 4 carriers and inputs the combined signal into the power amplifier 105, and the power amplifier 105 The combined signal is amplified, and the amplified signal is output to the duplexer 106 , then output to the antenna 107 by the duplexer 106 , and finally radiated by the antenna 107 .

The transmission process of sector 2 and sector 3 is the same as that of sector 1.

The receiving process of sector 1: the antenna 107 outputs a signal that combines the received four carrier signals to the duplexer 106, and the duplexer 106 transmits the signal to the splitting module 104-1, and the splitting module 104- 1. Divide the signal into two channels, one of which is divided into two channels by the branching module 104 and enter the receiving modules 102-1 and 102-2 respectively. The other signal passes through the branching module 204 through the jumper and then splits into two signals and enters the receiving modules 102-3 and 102-4 respectively. The receiving modules 102-1, 102-2, 102-3, and 102-4 process the four signals respectively.

The receiving process of sector 2 and sector 3 is the same as that of sector 1.

(2) When six sectors are configured, the working principle of the base station equipment is as follows:

The transmission process of sector 1: the transmitting module 101-1 outputs the first carrier signal, the transmitting module 101-2 outputs the second carrier signal, and the first carrier signal and the second carrier signal are combined through the combining module 103 And enter the power amplifier 105 through the combining module 103-1, the power amplifier 105 amplifies the signal, and outputs the amplified signal to the duplexer 106, and the duplexer 106 outputs it to the antenna 107, and the antenna radiates it.

The transmission process of sector 3 and sector 5 is the same as that of sector 1.

The transmission process of sector 2: the transmitting module 101-3 outputs the first carrier signal, the transmitting module 101-4 outputs the second carrier signal, and the first carrier signal and the second carrier signal are combined through the combining module 203 And enter the power amplifier 205 through the jumper 108 and the attenuation module 203-1, the power amplifier 205 amplifies the signal, and outputs the amplified signal to the duplexer 206, and the duplexer 206 outputs it to the antenna 207, and the antenna 207 will It radiates out.

The transmission process of sector 4 and sector 6 is the same as that of sector 2.

The receiving process of sector 1: the antenna 107 outputs a signal obtained by combining the received two carrier signals to the duplexer 106, and the duplexer 106 transmits the signal to the splitting module 104-1, and the splitting module 104- 1. Transmit the signal to the branching module 104, and the branching module 104 divides the signal into two paths, and the two paths of signals enter the receiving modules 102-1 and 102-2 respectively. The receiving modules 102-1 and 102-2 respectively process the two signals.

The receiving process of sector 3 and sector 5 is the same as that of sector 1.

The receiving process of sector 2: the antenna 207 combines the two received carrier signals and outputs a signal to the duplexer 207, and the duplexer 206 transmits the signal to the splitter through the attenuation module 204-1 and the jumper 208 Module 204, the branching module 204 divides the signal into two paths, and the two paths of signals respectively enter the receiving modules 102-3 and 102-4, and the receiving modules 102-3 and 102-4 respectively process the two paths of signals.

The receiving process of sector 4 and sector 6 is the same as that of sector 2.

It can be seen from the above description that the base station equipment supports three-sector configuration or six-sector configuration by changing the position of the jumper wire, but the jumper wire is easily damaged when it is plugged and unplugged many times, and it is difficult to find after the damage, which makes the base station equipment reliable. Poor maintenance. Moreover, in practical applications, there are many types of sector configuration supported by base station equipment. Different sector configuration forms correspond to different jumper methods. The jumper is completely handled manually, which is easy to cause confusion due to the many ways of jumper. , especially for maintenance personnel who are not very familiar with the working principle of base station equipment, jumper errors are more likely to occur, resulting in the base station equipment not working normally; at the same time, manual handling of jumpers is not conducive to the development of communication system automation.

Detailed ways

The core idea of the present invention is: the sector configuration of the communication device is not performed manually by jumping wires, but by an automatic control method. Firstly, it is determined that sector configuration needs to be performed; secondly, a corresponding sector configuration command is issued according to the sector configuration requirements; finally, the control command automatically controls the communication device to perform sector configuration. Therefore, the sector configuration in the communication device is realized through automatic control.

As an important communication device in a communication system, base station equipment also has sector configuration problems.

The present invention can adopt following method for the solution of base station equipment sector configuration:

The sector configuration command is issued by the control terminal of the base station equipment, and the electronic switch set in the base station equipment executes the sector configuration command. In addition to the electronic switch, the communication device may also use other devices capable of performing sector configuration operations according to the sector configuration command. The electronic switch needs to separately control the sector configuration of the signal transmitting part and the signal receiving part in the base station equipment. In the base station equipment, the system configuration file of the base station equipment can issue sector configuration commands. In this way, the sector configuration or the position status of the electronic switch corresponding to the sector configuration is set in advance in the system configuration file of the base station equipment. When the device starts the system configuration file, the system configuration file issues a sector configuration command, and the electronic switch can determine its corresponding position status according to the command, thereby completing the sector configuration of the base station device. The sector configuration command can also be issued by other files in the base station equipment, or through other communication equipment outside the base station equipment, such as a remote communication terminal. In this way, the remote control of the sector configuration of the communication equipment can be realized.
