Description

Background Art

[0002] The base station of the mobile communication network is inserted into the smart board to become an intelligent base station. It can interconnect and hang several ordinary base stations to make them intelligent, but due to the limitation of the computing power of the smart board, the number of managed base stations is limited. The number of base stations hanging under the intelligent base station is often configured according to the maximum traffic volume. In the high-speed rail mobile network scenario, the traffic of the high-speed rail base station has instantaneous effects and obvious tidal phenomena, and the traffic fluctuates with the passage of the high-speed rail. The capacity of the high-speed rail intelligent base station takes into account the maximum traffic. When the high-speed rail passes, it is the peak of traffic, resulting in the entire network being configured according to the peak of the high-speed rail train, and the utilization rate is low during idle time. At the same time, the intelligent base station can control the switch of the cell dormancy under the base station, but the switch cell dormancy information cannot be transmitted between intelligent base stations.

[0022] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0023] Figure 1 FIG. 1 shows an exemplary application system architecture diagram to which the train base station energy saving method in the embodiment of the present disclosure can be applied. Figure 1 As shown, the system architecture can include a smart board base station (Master base station), a base station (Slave base station), an operations and maintenance center (OMC) system and a cell.

[0024] Among them, the Master base station is responsible for controlling the switching of the cell sleep mode to its cell and notifying the Master base station to switch off the cell sleep mode; the sentinel Master base station (starting base station) is also responsible for receiving the OMC's command to switch off the cell sleep mode and identify the train entering the cell; the OMC is responsible for identifying the train in advance (which can be predicted through historical train traffic data or connected to the train website for inquiry) and notifying the sentinel Master base station (starting base station) to switch off the cell sleep mode and identify the train entering the cell; the Slave base station is responsible for executing the Master base station's smart board command to control the switching of the cell sleep mode and report the Master base station's train passing through the cell traffic, so that the Master base station can set the time window and notify the Master base station to switch off the cell sleep mode; the cell is responsible for executing the switch cell sleep mode command issued by the base station.

[0025] It should be noted that the smart board in the embodiment of the present disclosure is an intelligent single board used in the base station. The base station becomes an intelligent base station by inserting the smart board. The base station smart board usually has service identification capabilities, such as using artificial intelligence (AI) algorithms to accurately identify various services in the network, including short videos, uplink data services, VIP user services, etc., which serves as the basis for achieving differentiated services, allowing the network to dynamically adjust resource allocation according to the priority and characteristics of the service. In addition, the base station smart board can also implement energy-saving functions such as symbol shutdown, channel shutdown and cell sleep for the cell based on strategy analysis of the base station traffic.

[0026] First, in response to the above-mentioned problems, an energy-saving method for train base stations is provided in an embodiment of the present disclosure, which can be applied but not limited to. The method can be applied to electronic equipment that needs to improve the quality of high-speed rail users and services by realizing base station intelligence with the help of base station smart boards in high-speed rail mobile network scenarios. Compared with the capacity of high-speed rail smart base stations in related technologies taking into account the maximum traffic situation, the traffic peak is when the high-speed rail passes, resulting in the entire network being configured according to the peak of the high-speed rail train, and the utilization rate is low during idle time. At the same time, the smart base station can control the switch of the cell sleep mode under the base station, but the smart base stations cannot transmit the cell sleep mode switch information. The embodiment of the present disclosure notifies the smart base station to turn off the cell sleep mode and identify the train traffic. The smart base station turns the cell sleep mode on and off according to the traffic and vehicle speed. When the train enters the switching area between smart stations, the relevant information is transmitted to the next smart base station, so as to quickly turn the cell sleep mode on and off, reduce the smart base station monitoring traffic, and achieve the goals of energy saving of train base stations and increasing the number of cells under the smart base stations.

[0027] Figure 2 A schematic diagram of a train base station energy saving method in an embodiment of the present disclosure is shown, which is applied to an operation and maintenance center system. The method includes the following steps: S202, obtaining train number information on the target train line, where the train number information includes: target train arrival time and target train speed.

[0028] It should be noted that the target train route in the disclosed embodiment can be the route of any train, for example, the route of a high-speed railway or the route of a train. The disclosed embodiment takes the high-speed railway line as an example. The train number information of a certain high-speed railway may include the official name of the high-speed railway line, such as the Beijing-Shanghai High-Speed ​​Railway, the Shanghai-Nanjing Intercity Railway, etc.; the cities or regions connected by this high-speed railway line, for example, the Beijing-Shanghai High-Speed ​​Railway connects Beijing and Shanghai; the time when the line starts operation; the total mileage from the starting point to the end point, usually in kilometers (km); the designed maximum operating speed of the high-speed railway on the line, usually expressed in kilometers per hour (km / h); the names of the main stops along the high-speed railway; train schedules, fare information, operation schedules, etc.; the target train arrival time in the disclosed embodiment can be the time when the train arrives at a stop; the target train speed in the disclosed embodiment can be the average speed of the train in a certain area.

[0029] S204, based on the arrival time of the target train, the smart board that controls the sentinel base station turns off the sleep mode of the corresponding cell and identifies the train traffic of the target train, wherein the sentinel base station is the starting base station on the target train line, and the target train line includes multiple base stations. The smart board has the train traffic identification capability and is used to turn on or off the sleep mode of the cell.

[0030] It should be noted that the train traffic in the embodiments of the present disclosure generally refers to the services and technologies related to train communications during railway operations, generally including dispatching communications, passenger service communications, emergency communications, on-board telephone systems, and the application of wireless communication technologies. Train traffic covers all voice and data communication activities related to train operations and passenger services. These communication methods are essential to improving the safety, efficiency, and service quality of railway transportation. The sentinel base station in the embodiments of the present disclosure is a base station with a special role in the high-speed railway communication network environment in the high-speed railway mobile network. It is mainly used to monitor the entry of high-speed railway trains and to monitor the arrival of high-speed railway trains through the base station cells. Identify the Doppler shift when the user accesses to determine the high-speed user, determine the high-speed train entry according to the number of users, and sense the arrival of the high-speed train in advance like a "sentinel". The sentinel base station is usually deployed at key locations along the high-speed rail, such as near the high-speed rail station or at certain specific interval endpoints between two adjacent high-speed rail stations; the cell in the embodiment of the present disclosure refers to the geographical area covered by a base station in a cellular network, which is often called a cellular cell, and the sleep mode refers to a strategy for saving energy or optimizing resource usage. For example, during certain time periods, such as late at night, when user activity in a cell is significantly reduced, the base station can reduce power consumption by entering sleep mode.

[0031] S206, according to the target train speed, control the smart board of each base station on the target train line in turn to turn off the sleep mode of the corresponding cell.

[0032] It should be noted that the embodiment of the present disclosure dynamically adjusts the working state of each base station according to the speed of the train to achieve the purpose of energy saving and improving resource utilization efficiency. Specifically, when a train (such as a high-speed train) is traveling at high speed in a specific area, the users in the coverage area of ​​the base stations in the area stay for a very short time, which means that the necessity of maintaining full-power operation on these base stations is low. Therefore, when no train passes on the target train line, the base station can be switched to "sleep mode". When the train is about to pass a base station, the sleep mode of the corresponding cell is turned off and switched to working mode to ensure that the user experience on the train is not affected.

[0033] The train base station energy-saving method provided in the embodiments of the present invention comprises the following steps: first, obtaining train number information including the arrival time of the target train and the speed of the target train on the target train line; then, based on the arrival time of the target train, controlling the smart board of the sentinel base station to turn off the sleep mode of the corresponding cell and identifying the train traffic of the target train, wherein the sentinel base station is the starting base station on the target train line, and the target train line includes multiple base stations, and the smart board has the train traffic identification capability, which is used to turn on or off the sleep mode of the cell; finally, according to the speed of the target train, controlling the smart board of each base station on the target train line in turn to turn off the sleep mode of the corresponding cell. Compared with the related art in which the capacity of the train intelligent base station is considered under the condition of maximum traffic, when the train passes, there is a traffic peak, which causes the entire network to be configured according to the peak of the train, resulting in the problem of low utilization rate during idle time. The embodiment of the present disclosure identifies the arrival time of the train through the operation and maintenance center system and notifies the smart board of the sentinel base station (i.e., the starting base station on the train line) in advance to turn off the sleep mode of the corresponding cell, and identifies the train traffic, and notifies the smart boards of the subsequent base stations in sequence according to the train speed to turn off the sleep mode of the corresponding cell, thereby reducing the number of cells controlled by the smart board at the same time, improving the overall cell capacity of the train base station smart board, and realizing base station energy saving, thereby reducing the investment in smart base stations and operating costs such as power saving.

[0034] In some embodiments, after the smart board of each base station on the target train line is sequentially controlled to turn off the sleep mode of the corresponding cell according to the target train speed, the train base station energy-saving method in the embodiment of the present disclosure also includes: sequentially controlling the smart board of each base station on the target train line to identify the train traffic of the target train according to the target train speed; if the target cell identifies that the train traffic of the target train has changed, it is determined that the target train has left the target base station corresponding to the target cell, and the smart board of the target base station is controlled to turn on the sleep mode of the corresponding cell. Specifically, the embodiment of the present disclosure switches the base station that the train is about to leave or has passed through to "sleep mode", thereby shutting down some unnecessary hardware components or reducing their operating frequencies to reduce energy consumption.

[0035] In some embodiments, the multiple base stations included in the target train line in the disclosed embodiments can be divided into a master base station and slave base stations under the master base station. The smart board of the starting sentinel Master base station identifies the incoming train users and traffic in the corresponding cell, and notifies the subsequent smart boards of the slave base stations along the line under the same Master base station to turn off the sleep mode of the corresponding cell according to the train speed.

[0036] In some embodiments, after the target train is determined to leave the target base station corresponding to the target cell and the smart board of the target base station is controlled to turn on the sleep mode of the corresponding cell, the energy-saving method for the train base station in the embodiment of the present disclosure also includes: setting a time window based on the target train speed, and notifying the smart board of the next base station of the target base station to turn off the sleep mode of the corresponding cell within the time window. Specifically, the Slave base station in the embodiment of the present disclosure is responsible for executing the smart board instruction of the Master base station to control the switch cell sleep and report the Master base station high-speed rail through the cell traffic, so that the Master base station sets the time window and notifies the Master base station to turn off the cell sleep. The embodiment of the present disclosure predicts a time period through the train speed and the current position. During this time period, the train will enter the coverage of the next base station. The embodiment of the present disclosure will notify the next base station in advance to be ready to receive the connection request and resume normal working state within this time period. Through precise time window management, the base station can enter a low power consumption state when not in use, significantly reducing energy consumption; notifying the next base station in advance to be ready ensures that the user's experience is smooth during the network switching process and avoids problems such as disconnection.

[0037] In some embodiments, the disclosed embodiments control the smart board of the sentinel base station to turn off the sleep mode of the corresponding cell and identify the train traffic of the target train based on the arrival time of the target train, including: based on the arrival time of the target train, control the sentinel base station to switch from sleep mode to working mode; when the sentinel base station is in working mode, the smart board of the sentinel base station turns off the sleep mode of the corresponding cell and identifies the train traffic of the target train. Specifically, in the disclosed embodiments, during the time period when no trains pass, the relevant base stations can enter a low-power sleep mode, thereby reducing unnecessary power consumption; when a train is about to arrive, the system wakes up these base stations in advance to ensure that they can provide services when needed. By dynamically adjusting the working status of the base stations, limited network resources can be allocated more effectively, avoiding resource waste and improving the service quality of the overall network.

[0038] In some embodiments, the disclosed embodiments control the sentinel base station to switch from sleep mode to working mode based on the target train arrival time, including: sending a wake-up notification to the sentinel base station, the wake-up notification is used to notify the sentinel base station to stop sleeping. Specifically, when a train is about to enter the coverage of a sentinel base station, the disclosed embodiments wake up the base station in advance to ensure that the user will not experience interruptions or disconnections when the network coverage changes, which greatly improves the user's network experience, especially during high-speed movement, it is crucial to maintain a stable communication connection; at the same time, during the time period when no trains pass, the relevant base stations can enter a low-power sleep mode, thereby reducing unnecessary power consumption, and when a train is about to arrive, wake up these base stations in advance to ensure that they can provide services when needed.

[0039] In some embodiments, the multiple base stations included in the target train line in the embodiment of the present disclosure are also used to switch from sleep mode to working mode in response to the wake-up notification from the sentinel base station when in sleep mode, and send the wake-up notification to the next base station in turn. Specifically, the embodiment of the present disclosure uses a chain wake-up mechanism to ensure that each base station passed by the train can be awakened and restored to normal working state in time before the train arrives, so that users can enjoy continuous and stable communication services throughout the journey and avoid disconnection or interruption; each base station is dynamically adjusted according to the actual position and speed of the train to ensure that the service is provided immediately when the train enters its coverage area; in addition, only when the train is about to enter the coverage area of ​​a certain base station will the base station be awakened and start working. During other time periods, the base station can remain in a dormant state, thereby greatly reducing unnecessary power consumption.

[0040] In some embodiments, the embodiments of the present disclosure take the high-speed rail as an example. When a user on the high-speed rail passes through the high-speed rail cell n, the intelligent base station can identify high-speed and low-speed users through Doppler shift technology, and at the same time identify the high-speed rail users entering the cell according to the number of train users entering the cell and the traffic volume. Figure 3 As shown, the specific steps include: S302, OMC identifies the arrival time of the high-speed train according to the high-speed train arrival prediction algorithm (which can be intelligently predicted through historical high-speed train traffic data or connected to the high-speed train website for query and prediction) and notifies the smart board of the sentinel Master base station n (the starting base station of the high-speed train) in advance to turn off the cell sleep of cell n, and identifies the high-speed train traffic.

[0041] S304, the smart board of Master base station n identifies the high-speed train users and traffic in community n.

[0042] S306, the smart board of the Master base station n notifies the subsequent high-speed rail cells of the Slave base stations from "n+1" to "n+n" to shut down the cell dormancy according to the vehicle speed.

[0043] S308, the smart board of the Master base station n recognizes that the high-speed rail has left n through the traffic changes in the cell n, and notifies the Master base station n to put the cell n into sleep mode.

[0044] S310, the smart board of the Master base station n recognizes that the high-speed rail enters the cell n+y through the cell n+y traffic, and notifies the high-speed rail base station m to shut down the cell m dormancy within a preset time window.

[0045] S312, the smart board of Master base station m turns off the sleep state of cell m and starts to recognize the entry of high-speed rail.

[0046] S314, the traffic of the smart board of Master base station n recognizes that the high-speed train has left n+n and puts cell n+n into sleep mode.

[0047] S316, Master base station m and Master base station o repeat S306 to S314.

[0048] … S3n, the smart board of Master base station o recognizes that the high-speed rail enters the community o+y through the community o+y traffic. The smart board determines that there is no subsequent access to the high-speed rail base station, and starts the o+y community hibernation after the high-speed rail leaves.

[0049] S3 (n+2), Master base station o recognizes through cell o+n traffic that the high-speed train has left o+n and puts cell o+n into sleep mode.

[0050] In some embodiments, the smart board of the Master base station n in the disclosed embodiment sequentially notifies the high-speed rail cells of the subsequent Slave base stations from "n+1" to "n+n" to shut down and put the cells into sleep mode according to the vehicle speed; the smart board of the Master base station n recognizes that the high-speed rail enters the cell n+y through the cell n+y traffic, and notifies the high-speed rail base station m to shut down and put the cell m into sleep mode during the preset time window; the smart board of the Master base station o recognizes that the high-speed rail enters the cell o+y through the cell o+y traffic, and the smart board determines that there is no subsequent entry into the high-speed rail base station, and turns on the o+y cell sleep mode after the high-speed rail leaves.

[0051] In some embodiments, the disclosed embodiments use the train sentry base station smart board to identify the train users and traffic in the starting cell, and coordinate with the smart boards of base stations along the line to control the sleep mode opening and closing of cells along the line according to the speed of the train, thereby reducing the number of cells controlled by the smart board at the same time, and improving the overall cell capacity of the train base station smart board, thereby reducing the investment in smart base stations and operating costs such as power saving.

[0052] Based on the same inventive concept, the present disclosure also provides a train base station energy-saving device, such as the following embodiment. Since the principle of solving the problem in the device embodiment is similar to that in the above method embodiment, the implementation of the device embodiment can refer to the implementation of the above method embodiment, and the repeated parts will not be repeated.
