Detailed Description
The technical solution of the present disclosure is further described in detail by the accompanying drawings and examples.
The flow chart of some embodiments of the base station control method of the present disclosure is shown in fig. 1, and may include steps 101 to 103.
In step 101, measurement fingerprint information of a location where a terminal is located is obtained from a user terminal, where the measurement fingerprint information includes a base station signal reception strength, a base station signal arrival angle, and a time delay.
In some embodiments, the ue may perform the operation of reporting the measured fingerprint information under a certain trigger condition. In some embodiments, the terminal reports the measurement fingerprint information when entering a macro base station weak coverage area or a macro base station coverage blind area, so that the micro base station is attempted to be triggered to be started only when the communication quality is affected, and the reliability of communication is ensured. In other embodiments, the terminal may also report the fingerprint information when entering the coverage of the deployed micro base station (the core network may notify the terminal of entering the coverage of the deployed micro base station according to the deployment range of the micro base station), so as to provide the terminal with the optimal communication effect while reducing energy consumption.
In step 102, according to the measured fingerprint information and the offline fingerprint library, a micro base station corresponding to the coverage area of the micro base station entered by the user terminal is determined. The micro base station may be a 5G micro base station. In some embodiments, the offline fingerprint library stores the measured fingerprint information of each reference point in the case of the micro base station in the sleep state. In some embodiments, the measured fingerprint information may be matched with fingerprint information in an offline fingerprint library, a location of the terminal is determined, and a micro base station closest to the terminal is determined according to the location of the terminal.
In step 103, the determined micro base station is woken up.
By the method, the micro base station can be awakened after the terminal enters the coverage range of the micro base station, so that the micro base station does not need to be kept in a normally open state, the working time of the micro base station is shortened, the energy consumption of the micro base station is reduced, and the effect of saving energy under the condition of not influencing the user experience is achieved.
In some embodiments, after the 5G micro base station is turned on, a certain time interval T is set to measure uplink and downlink traffic data and data such as a PRB (Physical Resource Block) utilization rate of the base station, and if a corresponding parameter is kept at zero or a lower level all the time, it indicates that the base station has completed a corresponding service, and may be turned off to save electric energy. The server sends an instruction to enable the base station to enter the dormant state again and wait for being awakened next time. The base station control method can also comprise steps 104-105.
In step 104, it is determined whether the uplink and downlink data traffic of the awake micro base station is 0 within a predetermined time length. And if the uplink and downlink flow does not exist for the preset time length, determining that no terminal is connected to the micro base station.
In step 105, the micro base station is controlled to resume the sleep state and wait for the next wake-up.
By the method, no terminal is using the micro base station can be timely found according to the uplink and downlink flow of the micro base station, so that the micro base station can be dormant, and the energy-saving effect is further optimized.
When a user moves from the coverage area of one base station to the coverage area of another base station, the user needs to locate the base station to obtain the position information of the base station so as to decide whether to start a neighbor micro base station. The core idea of the position fingerprint positioning technology is to establish a database by acquiring different position information and fingerprint information received at the position, and compare the actually received fingerprint with fingerprint points in the database one by one, thereby realizing the positioning of a target. After fingerprint information matching and positioning are completed, a user can access to the decision-making starting 5G micro base station, so that the electric energy of the base station is saved, and meanwhile, the good service quality of the user can be ensured.
In some embodiments, user priority may be set, and for a high priority user, multiple micro base stations may be woken up to improve the quality of service for the high priority user.
In some embodiments, a premium user may be determined and set a user priority level for the carrier enterprise based on different criteria. After finishing the fingerprint matching operation, the user with high priority can directly start a plurality of adjacent 5G micro base stations under the condition of starting the nearest 5G micro base station, thereby providing better service quality for the user. Flow diagrams of further embodiments of the base station control methods of the present disclosure are shown in fig. 2.
In step 201, measurement fingerprint information of a location where a terminal is located is obtained from a user terminal.
In step 202, user priorities are determined. In some embodiments, at least two priorities may be set, wherein for a high priority user, multiple micro base stations can be woken up, e.g. all micro base stations located at the user terminal location; for a user with low priority, only one micro base station closest to the user terminal is awakened.
In other embodiments, more than 2 priorities may be set, each priority setting an upper limit of the number of micro base stations that can wake up, i.e. a predetermined number, which is not less than 1, wherein the predetermined number corresponding to the high priority is greater than the low priority. And selecting the smaller number as the number of the micro base stations to be awakened according to the number of the micro base stations around the position of the user and the upper limit of the number of the micro base stations capable of being awakened.
In step 203, the determined micro base station is awakened. In some embodiments, the number of micro base stations to wake up may be determined by the means in step 202.
In step 204, a corresponding number of micro base stations are woken up.
For operator enterprises, high-quality users can be determined according to different standards, and user priority levels can be set for the high-quality users. After the user with high priority finishes the fingerprint matching operation, under the condition of starting the nearest 5G micro base station, a plurality of adjacent 5G micro base stations can be directly started, and better service quality is provided for the micro base stations.
In some embodiments, an offline fingerprint repository may be pre-established. Based on the positioning and base station arrangement requirements, a plurality of reference points are respectively selected to acquire fingerprint information when a plurality of indoor 5G micro base stations are not started.

In some embodiments, the possible distribution reference points of the selected 5G micro base station can be determined according to the indoor environment characteristics in the non-turned-on state of the base station.

In some embodiments, reference point fingerprint information data may be collected by a CQT (Call Quality Test). In some embodiments, the acquired fingerprint information may be sorted into a set database according to a certain encoding format.
In step 304, an offline fingerprint library is generated from the fingerprint information for the plurality of reference points. In some embodiments, the data may be stored in a database storage process according to { RP, longitude, latitude, RSSI, AOA, TD }, where RP represents a reference point, the longitude and latitude represent latitude and longitude position coordinates of the reference point, respectively, the RSSI represents a base station received signal strength of the reference point, the AOA represents a wave radiation propagation direction of a base station signal to an observation point, that is, an arrival angle parameter, and the TD represents a real-time delay value obtained at the reference point.

By the method, the fingerprint data of the reference point in the dormant state of the micro base station can be obtained and stored in the database, and the accuracy of position determination according to the measurement fingerprint information reported by the user terminal is improved.
