Description

A method, system and device for controlling the working state of a small base station

technical field

The present invention relates to the technical field of communications, and in particular to a method, system and device for controlling the working state of a small base station.

Background technique

In a current mobile communication network, a combination of a macro base station and a small base station (mainly including a micro base station and a pico base station) is generally used to provide services for user terminals. Specifically, a macro base station is set up for areas where user terminals are scattered, and the macro base station can cover a larger area. In areas where there are no communication signals (may be referred to as blind areas), small base stations are usually set up, and the small base stations have a relatively small coverage area and support a relatively small number of user terminals.

In practical applications, in addition to adopting the combination of macro base stations and small base stations to arrange wireless communication networks, combined with the actual situation of limited frequency resources for providing wireless communication, it is set that macro base stations and small base stations use signals of the same frequency for users For terminals to provide services, the method of building a wireless communication network using macro base stations and small base stations of the same frequency is generally called co-frequency networking.

One of the characteristics of co-frequency networking is that the interference between base stations (including macro base stations and small base stations) is relatively large. Based on this feature, each macro base station can be determined according to the power of interference signals generated by adjacent macro base stations. Its own coverage area can also be understood as each macro base station can determine its own coverage area according to the signal quality of the downlink signal it sends and the uplink signal it receives. Generally, the area covered by the macro base station is called a macro base station cell, and the macro base station transmits The signal to the terminal is called the downlink signal, and the signal sent by the terminal received by the macro base station is called the uplink signal. Hereinafter, the downlink signal sent by the macro base station and the uplink signal sent by the terminal within the coverage of the macro base station are collectively called the macro base station cell transmission signal of. Usually, the method of judging signal quality is mainly determined by the signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR), specifically, if the ratio of the power of the signal to the power of the interference signal and the power of the noise signal (that is, the signal to interference and noise ratio) If it is less than the set threshold value, the signal quality of the signal is considered to be poor; otherwise, the signal quality of the signal is considered to be relatively good. In practical applications, noise signals and interference signals will interfere with the available signals in communication. For description, noise signals and interference signals are collectively referred to as interference signals below.

FIG. 1 shows a schematic diagram of the coverage area of a macro base station, where the first macro base station cell 101, the second macro base station cell 102, and the third macro base station cell 103 (in practical applications, there may be multiple macro base station cells, here referred to as The first macro base station cell 101, the second macro base station cell 102, and the third macro base station cell 103 are used as examples for corresponding description) adjacent to each other, and the small base station cell 104 is for the first macro base station cell 101, the second macro base station cell 102 And the third macro base station cell 103 covers the area covered by the base station set in the blind zone or weak zone between coverage areas.

The macro base stations in the first macro base station cell 101, the second macro base station cell 102, and the third macro base station cell 103 determine their own coverage areas according to the signal quality of the signals processed by themselves. Specifically, when the macro base station in the first macro base station cell 101 The station detects the interference signal in the adjacent or overlapping area between the first macro base station cell 101 and the second macro base station cell 102 (that is, the interference signal generated by the second macro base station cell 102 to the first macro base station cell 101), causing its own processing After the signal-to-interference-noise ratio of the signal is less than the set threshold value (that is, the interference signal intensity of the interference signal generated by the second macro base station cell 102 is relatively large), the area of the first macro base station cell 101 is reduced, and the second macro base station cell The macro base station of the cell 102 provides communication signals for the terminals in the adjacent or overlapping area, and further, the macro base station of the third macro base station cell 103 may detect that the adjacent first macro base station cell 101 has caused a disturbance to the adjacent or overlapping area. The interference signal has little effect on the signal quality of the signal processed by itself, and the area of the third macro base station cell 103 will be enlarged.

When the macro base stations in the first macro base station cell 101, the second macro base station cell 102, and the third macro base station cell 103 adjust their respective coverage areas according to the signal quality of the signals processed by themselves, the area covered by the small base station cell 104 will also be affected. The corresponding impact, for example, when the macro base station of the third macro base station cell 103 expands its coverage area, it may cover the area covered by the small base station cell 104 at the same time. In practical applications, a small base station is generally connected with multiple macro base stations Adjacent, in this way, there is a problem that the area covered by multiple macro base stations expands to the area covered by one small base station, which in turn causes the signal used for communication in the area covered by the small base station to be interfered by the signals of multiple base stations, thus affecting the area covered by the small base station. The signal quality of the signal used for communication in the zone.

The embodiments are described, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention. And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

The scheme for controlling the working state of the small base station involved in the embodiment provided by this scheme can be described by taking the structural diagram of the wireless communication network system shown in Figure 2 as an example. Specifically, the wireless network system shown in Figure 2 mainly includes a core network equipment 201, a first macro base station 202, a second macro base station 203, and a third macro base station 204 (there may be multiple macro base stations in practical applications, here the first macro base station 202, the second macro base station 203, and the third macro base station 204 as an example) and the small base station 205, wherein:

The small base station 204 is a small base station set for weak or blind areas in the coverage areas of the first macro base station 202, the second macro base station 203, and the third macro base station 204. In practical applications, the first macro base station 202, the second macro base station 203, and the Areas covered by the third macro base station 204 are adjacent to each other. In the technical solution provided by this application, a terminal communication module 205A, a small base station communication module 205D, and a power supply module 205B for providing power to the small base station 205 are provided for the small base station 205. The terminal communication module 205A and the power supply module 205B can be set in Inside the small base station 205, as shown in Figure 2; the terminal communication module 205A and the power module 205B can also be arranged outside the small base station as required, as shown in Figure 3, and the terminal communication module 205A and the power module 205B are connected to the small base station The distance is within the set range, so as to ensure that the power module can supply power to the small base station normally, and ensure that the terminal communication module and the small base station can normally exchange information. For ease of description, in the present application, the terminal communication module disposed inside the small base station and the terminal communication module disposed outside the small base station are collectively referred to as the terminal communication module.

In the wireless communication network system shown in FIG. 2 and FIG. 3 , the terminal communication module 205A is used to communicate downlink signals between the small base station 205 and the first macro base station 202, the second macro base station 203, and the third macro base station 204 respectively. The quality is detected, and uplink signals are sent to the first macro base station 202 , the second macro base station 203 and the third macro base station 204 . In practical applications, the terminal communication module 205A can be powered by the power module 205B of the small base station 205, and when the power module 205B is powered off, the terminal communication module 205A can be powered by the backup power module 205C.

Further, the quality information of the uplink signal and the quality information of the downlink signal are used by the core network device 201 to determine whether to instruct the small base station 105 to stop providing services to terminals in the coverage area.

The core network device 201, in actual application, the core network device 201 can be connected to the macro base station and the small base station through the network transmission equipment. Here, for the convenience of describing this solution clearly, it reflects the relationship between the core network device 201 and each macro base station and small base station relationship, the network transmission device is not set in Figure 2 and Figure 3 . The core network equipment 201 can manage the macro base stations and the small base stations shown in FIG. 2 and FIG. The power module 205B of the base station 205 supports remote control, and the core network device 201 can also remotely control the power module to perform power-on and power-off operations.

Embodiment one

Embodiment 1 of the present application provides a method for controlling the working state of a small base station. This method can be applied to the wireless communication network system shown in FIG. 2 and FIG. The interference of the signal used for communication in the coverage area of the base station, thereby improving the signal quality of the signal used for communication in the area.

FIG. 4 shows a schematic flow chart of controlling the working state of a small base station provided in Embodiment 1 of the present invention. Specifically, as shown in FIG. 4 , the process of controlling the working state of a small base station mainly includes the following steps:

Step 401: Obtain downlink signals between the terminal communication module corresponding to the small base station and each macro base station adjacent to the small base station, and determine quality information of each downlink signal.

In this step 401, the device used to obtain the downlink signal and determine the quality information of the downlink signal may be a terminal communication module arranged in the small base station, or a terminal communication module arranged outside the small base station; the obtained downlink signal is The downlink signal sent by each macro base station adjacent to the small base station, the downlink signal can be the downlink signal sent by each macro base station to each terminal in the coverage area of the small base station, or it can be the downlink signal sent by each macro base station to a designated terminal in the area The downlink signal, or the downlink signal sent by each macro base station to the small base station and needs to be forwarded by the small base station. In practical applications, the terminal communication module can obtain the above-mentioned downlink signal to determine the signal sent by each macro base station appearing in the coverage area of the small base station The quality information of the downlink signal is to determine the quality information of the downlink signal between the terminal communication module and each macro base station adjacent to the small base station. In addition, the terminal communication module corresponding to the small base station can be a terminal communication module installed in the small base station in practical applications, or a terminal communication module installed outside the small base station and within a set range from the small base station. module. The terminal communication module appearing in this solution may be the terminal communication module set in any of the above two ways of setting the terminal communication module.

Step 402: Report the determined quality information of the downlink signal to the core network device.

In this step 402, the equipment used to report the quality information of the downlink signal to the core network equipment is the same as above, and may be a terminal communication module installed in the small base station, or may be a terminal communication module installed outside the small base station.

Step 403, sending an uplink signal to each macro base station adjacent to the small base station.

In step 403, same as step 401 and step 402 above, the equipment that sends uplink signals to the macro base stations adjacent to the small base station can be a terminal communication module installed in the small base station, or a terminal communication module installed outside the small base station module. In practical applications, the small base station can save the information of the adjacent macro base stations, for example, store the identities of the adjacent macro base stations corresponding to other information related to each macro base station locally for calling by the terminal communication module, Alternatively, the identification of each macro base station is directly stored in the terminal communication module corresponding to other information related to each macro base station, so that the terminal communication module can directly send an uplink signal to the corresponding macro base station according to the locally stored information of the macro base station, Further, the macro base station that sends and receives the downlink signal in step 401 may be identified according to the saved information of each macro base station.

Step 404, the macro base station receives the uplink signal, and determines the quality information of the received uplink signal.

Step 405, the macro base station sends the quality information of the uplink signal to the core network equipment.

So far, the macro base station and the terminal communication module have completed the operations performed in the process of controlling the working state of the small base station, wherein the order of execution of steps 401 to 402 and steps 403 to 405 can be flexibly executed according to the actual situation, for example, in the execution step Step 403 to step 405 are executed during the process from step 401 to step 402, or step 401 to step 402 is executed after step 403 is executed, and step 404 to step 405 can be executed simultaneously during the execution of step 401 to step 402, or , according to actual needs, other execution sequences are adopted, or steps 401 to 402 and steps 403 to 405 are respectively executed according to their respective setting methods. The execution modes of steps 401 to 402 and steps 403 to 405 can be flexibly set according to actual needs, and will not be listed one by one here.

Step 406, the core network equipment receives the quality information of the downlink signal between the terminal communication module and each macro base station adjacent to the small base station, and the quality information of the uplink signal.

In this step 406, the time when the core network equipment receives the quality information of the downlink signal and the time when the quality information of the uplink signal is received are actual receiving times, corresponding to the time when the terminal communication module reports the quality information of the downlink signal through the macro base station and the time when the macro base station reports the quality information of the downlink signal. The time when the station reports the quality information of the uplink signal, therefore, the core network equipment does not necessarily receive the quality information of the downlink signal and the quality information of the uplink signal at the same time. In addition, corresponding to step 402, the quality information of the downlink signal received by the core network equipment is the quality information of the downlink signal reported by the terminal communication module, and corresponding to step 405, the quality information of the uplink signal received by the core network equipment is the The quality information of the uplink signal reported by the macro base station. In practical applications, the core network equipment can store the corresponding relationship between the small base station and the adjacent macro base stations, so that the core network equipment can perform quality information on the quality information of the received uplink signal and the quality information of the downlink signal according to the stored corresponding relationship. After processing, the indication information is sent to the corresponding small base station.

Step 407: After determining that the downlink signal quality and the uplink signal quality between the terminal communication module and at least one of the macro base stations adjacent to the small base station meet the conditions for controlling the small base station to stop serving, the core network device instructs the small base station to stop Provide services to each terminal in the coverage area.

In step 407, the conditions for stopping the service of the small base station are controlled. Specifically, considering the requirements of wireless communication in practical applications, the uplink between the terminal communication module and at least one of the macro base stations adjacent to the small base station The signal quality and the downlink signal quality are higher than the corresponding set threshold values at the same time, as the condition for controlling the small base station to stop serving, that is, between at least one macro base station among the macro base stations adjacent to the small base station. When the quality of the uplink signal and the quality of the downlink signal are both higher than the corresponding set thresholds, the small base station is instructed to stop providing services to the terminals in the coverage area. Wherein, the threshold value can be set according to the requirements for signal quality in actual communication. For example, the signal quality requirements for signals used for communication (including uplink signals and downlink signals) are relatively high according to needs, then the corresponding needs will be The threshold value can be set relatively large, or the threshold value can be set relatively small according to the general requirement on the signal quality of the signal used for communication.

Step 408, the small base station receives the indication information sent by the core network equipment, and controls the small base station to stop providing services to terminals in the coverage area according to the indication information.

In this step 408, the indication information is the information sent by the core network equipment instructing the small base station to stop providing services to the terminals in the coverage area. In practical applications, the indication information may be the information instructing the power module of the small base station to stop supplying power to the small base station so that the small base station stops providing services to the terminals in the coverage area. In addition, the instruction information can also be other information that enables the small base station to stop providing services to the terminals in the coverage area, for example, instructing the small base station to stop receiving, transmitting and The operation of processing information is used to stop providing services to each terminal in the coverage area. Specifically, corresponding settings may be made according to the actual configuration of the small base station, which will not be repeated here. In addition, when the small base station receives the indication information sent by the core network equipment, the small base station can directly receive the indication information, and according to the indication information, control the power module included in itself to stop supplying power to the small base station, or the power module of the small base station supports remote control The power supply module of the small base station receives the indication information, and then stops supplying power to the small base station according to the indication information, so that the small base station stops providing services to terminals in the coverage area. Here, the present application uses the small base station to receive indication information for corresponding description.

So far, the process of controlling the working state of the small base station ends.

In the process corresponding to Figure 4, the core network equipment can receive the quality information of downlink signals between the terminal communication module and the macro base stations adjacent to the small base station reported by the terminal communication module, and the quality information of the downlink signals between the small base station and the small base station reported by each macro base station. The quality information of the uplink signal, and according to the quality information of the received downlink signal and the quality information of the uplink signal, determine that the signal quality between at least one macro base station and the terminal communication module corresponding to the small base station in each macro base station meets the set condition , instruct the small base station to stop providing services to the terminals in the coverage area, so that when the coverage area of the small base station overlaps with the coverage area of at least one of the adjacent macro base stations, the small base station stops providing services to the coverage area. Each terminal provides services, thereby reducing interference to signals used for communication in the coverage area of the small base station, and improving signal quality of signals used for communication in the area.

In step 402 included in the flow corresponding to FIG. 4 , the terminal communication module set in the small base station reports the determined quality information of the downlink signal to the core network equipment, and the terminal communication module can pass through the adjacent small base station At least one macro base station in each macro base station reports the determined quality information of the downlink signal to the core network equipment. Specifically, FIG. 5 shows the process of reporting the quality information of the downlink signal by the terminal communication module provided in Embodiment 1 of the present invention. Schematic diagram, as shown in Figure 5, the process of the terminal communication module reporting the quality information of the downlink signal mainly includes the following steps:

Step 501, the terminal communication module determines the quality information of downlink signals sent by adjacent macro base stations.

Step 502, the terminal communication module sends the determined quality information of the downlink signal to any macro base station among the adjacent macro base stations.

Step 503, the macro base station receiving the quality information of the downlink signal sends the quality information of the downlink signal to the core network equipment.

So far, the process of reporting the quality information of the downlink signal by the terminal communication module ends.

Figure 5 corresponds to the flow of the terminal communication module reporting the quality information of the downlink signal, which is a preferred implementation mode for the terminal communication module to report the quality information of the downlink signal provided by Embodiment 1 of the present invention. In practical applications, the terminal communication module can The setting of the communication network system determines the path for reporting the quality information of the downlink signal. For example, the quality information of the downlink signal can be reported to the core network device through other equipment for forwarding information in the wireless communication network system.
