Description

Technical Field

[0001] The present application relates to the field of mobile communications, and in particular to a method, device and non-volatile storage medium for adjusting a base station energy-saving strategy. Background Art

[0002] As people's demand for mobile networks increases, mobile network operators usually deploy 4G and 5G private networks for high-speed rail coverage. In order to ensure the mobile Internet experience of high-speed rail users, 4 / 5G network base station equipment usually needs to remain in continuous working state throughout the day, but in fact the base station only needs to remain in working state when the train passes through the coverage area of ​​the base station. Maintaining continuous full-performance working state is bound to cause a huge waste of power resources, especially 5G base stations have high frequencies, large bandwidths, and many channels. The current energy saving of base stations for rail transit is mainly high-speed rail base station energy saving.

[0003] The energy-saving methods used in related technologies have the problem of poor energy-saving effect. For example, the deep sleep solution at night cannot accurately save energy during the idle time of most base stations during the day, and the energy-saving efficiency is low; and some sections of the road have opened "high-speed rail sleeper", which will affect the use of users on such trains. Due to the development of emergencies such as weather and letting cars, train delays often occur. The use of high-speed rail operation time and passenger estimation schemes to save energy in advance may result in the base station being unable to wake up in time when the train actually passes, affecting user experience and energy-saving effects. When using the high-speed user identification high-speed rail entry area dynamic adjustment scheme, due to the difference in speed during the operation of the train, there is a possibility of letting the train slow down when encountering temporary situations. If the speed judgment threshold is set too high, it may not be accurately identified when the train passes, resulting in the energy-saving base station not being able to wake up in time, affecting user perception; on the contrary, if the speed judgment threshold is set too low, it may cause the section parallel to the high-speed to misjudge the high-speed car user as a high-speed rail, thereby waking up the high-speed rail base station in advance and reducing energy-saving efficiency.

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0034] The information collected in the embodiments of the present application is information and data authorized by the user or fully authorized by all parties, and the collection, storage, use, processing, transmission, provision, disclosure and application of the relevant data comply with the relevant laws, regulations and standards of the relevant regions, take necessary confidentiality measures, do not violate public order and good morals, and provide corresponding operation entrances for users to choose to authorize or reject automated decision-making results; if the user chooses to reject, the expert decision-making process will be entered.

[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0036] In order to better understand the embodiments of the present application, the technical terms involved in the embodiments of the present application are explained as follows:

[0037] 5G-A interawareness: 5G base stations have communication service capabilities and specific wireless perception capabilities. The perception principle is similar to that of radar. When the wireless signals emitted by 5G base stations pass through different media or objects, they will undergo different changes due to reflection, refraction, and scattering. By analyzing these changes, the size, position, speed, and other information of the object can be perceived. Currently, it has been piloted in the fields of low-altitude drone supervision, channel ship monitoring, and road traffic control.

[0038] The current energy-saving methods of technology can be roughly summarized into three categories:

[0039] The first type of nighttime deep sleep solution: Since high-speed rail usually only operates during the day and is not in operation at night, operators usually use the method of deep sleep during the non-operating time at night to solve the problem. However, most base stations cannot save energy accurately during idle time during the day, and the energy saving efficiency is low; and some sections of the route have opened "high-speed rail sleeper", so this solution will affect the use of users on such trains.

[0040] The second type of high-speed rail operation timetable and passenger calculation plan: Based on the high-speed rail operation timetable, ticket sales, and the base stations where the train passes, network load, etc., high-speed rail trains are often delayed due to unexpected situations such as weather and giving way to other vehicles during operation. Using pre-calculation to save energy may result in the base station being unable to wake up in time when the train actually passes, affecting user experience and energy-saving effects.

[0041] The third type of high-speed user identification and dynamic adjustment plan for high-speed rail entry areas: measure the Doppler frequency deviation of mobile phone users through 4 / 5G network base stations, calculate whether there are high-speed mobile users to achieve the purpose of identifying the approach or distance of high-speed trains, thereby judging the base station coverage range that the high-speed train is about to enter, and assisting the system to realize the start-up and shutdown energy-saving strategy. However, when the train passes through the first station of the super cell, if all users happen to be in an idle state, the base station will not be able to recognize the train passing, resulting in the inability to wake up its associated base stations. Since the speed of trains varies during operation, there is a possibility of slowing down the train when encountering temporary situations. If the speed judgment threshold is set too high, it may not be accurately identified when the train passes, resulting in the energy-saving base station not being able to wake up in time, affecting user perception; conversely, if the speed judgment threshold is set too low, it may cause the section parallel to the highway to misjudge high-speed car users as high-speed railways, thereby waking up the high-speed railway base station in advance and reducing energy-saving efficiency.

[0042] In the related art, various energy-saving methods all have the problem of single energy-saving method and poor energy-saving effect. In order to solve this problem, the embodiments of the present application provide relevant solutions, which are described in detail below.

[0043] According to an embodiment of the present application, a method embodiment of a method for adjusting a base station energy-saving strategy is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0044] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Figure 1 The hardware structure block diagram of a computer terminal for implementing a method for adjusting a base station energy-saving strategy is shown. Figure 1As shown, the computer terminal 10 may include one or more (102a, 102b, ..., 102n are used to illustrate) processors 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA), a memory 104 for storing data, and a transmission module 106 for communication functions. In addition, it may also include: a display, an input / output interface (I / O interface), a universal serial bus (USB) port (which may be included as one of the ports of the BUS bus), a network interface, a power supply and / or a camera. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above electronic device. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations are shown.

[0045] It should be noted that the one or more processors 102 and / or other data processing circuits described above may generally be referred to herein as "data processing circuits". The data processing circuits may be embodied in whole or in part as software, hardware, firmware, or any other combination thereof. In addition, the data processing circuit may be a single independent processing module, or may be incorporated in whole or in part into any of the other components in the computer terminal 10. As described in the embodiments of the present application, the data processing circuit acts as a processor control (e.g., selection of a variable resistor terminal path connected to an interface).

[0046] The memory 104 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the method for adjusting the energy-saving strategy of the base station in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, that is, the method for adjusting the energy-saving strategy of the base station is realized. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the computer terminal 10 via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0047] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the computer terminal 10. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0048] The display may be, for example, a touch screen liquid crystal display (LCD) that enables a user to interact with a user interface of the computer terminal 10 .

[0049] In the above operating environment, the embodiment of the present application provides a flow chart of a method for adjusting a base station energy saving strategy, such as Figure 2 As shown, the method comprises the following steps:

[0050] Step S202, determining a sentinel base station from all base stations that the train passes through on the route, wherein the sentinel base station is used to sense the approach or departure of the train, and determining the base stations on the train route except the sentinel base station as ordinary base stations.

[0051] In the technical solution provided in step S202, sentinel base stations are located at some key locations, and 5G base stations at special key locations such as high-speed railway station entry and exit track change and line merging points, multi-line track change and line merging points, and single line bifurcations are selected as sentinel base stations. The sentinel base station is a base station with synesthesia perception capability. Its main function is to sense the approach or distance of rail trains, and provide a decision basis for the subsequent energy-saving start and stop of 4 / 5G base stations.

[0052] Sentinel base stations can include the following types:

[0053] Station entry and exit sentry base station: a base station that all trains must pass through. The station entry and exit sentry base station can not only ensure that all trains passing through and their running directions can be sensed and identified, but also correct the time difference between the subsequent base station skills caused by the different train stop times, thereby improving the accuracy of energy saving.

[0054] Sentry base stations at forks: When a train leaves a station, it may enter a different line at a fork, or enter a track that does not lead to a station at a fork in a city. Therefore, sentry base stations must be deployed in each direction of the fork to identify the subsequent train operation plan, such as Figure 4 A base station distribution diagram is provided, showing the distribution of sentinel base stations at the fork.

[0055] Boundary sentinel base station: It is mainly used for the boundary between energy-saving identification area and non-energy-saving identification area, which can usually be regarded as provincial or municipal boundaries. When a train enters the energy-saving identification area from the non-energy-saving identification area, the energy-saving system cannot accurately save energy for the base station between the nearest stations at the boundary value because there is no sentinel base station to sense the train entering. Therefore, a boundary sentinel base station must be deployed in this area, such as Figure 5 A base station distribution diagram is provided, showing the distribution of border sentinel base stations.

[0056] It should be noted that after determining the above-mentioned sentinel base stations, it is necessary to arrange and encode the "sentinel" base stations in order according to the direction of the train and the order of passing. The purpose of encoding is to accurately send energy-saving change instructions to subsequent base stations. Figure 6 As shown in the figure, a sentinel base station distribution diagram is provided. When the sentinel base station at the "X boundary" senses the approach of a train, the base station energy-saving system sends the energy-saving change command to the 4 / 5G base station between the "X boundary" sentinel station and the "A station west", but not to the "B station west"; when the "B station east" sentinel station senses the approach of a vehicle, it needs to send the energy-saving and change command to the 4 / 5G base stations in the two sentinel intervals of "A fork north / south" at the same time to avoid the base stations on the A / B routes from being unable to wake up in time. The same goes for the opposite.

[0057] Step S204, determining movement information of the first train according to the reflection signal of the narrow beam signal transmitted by the sentinel base station, wherein the first train is any rail train in the process of moving.

[0058] In the technical solution provided in step S204, the sentinel base station transmits a narrow beam signal through the 5G cell and then receives the reflected signal to identify the object's position, size, speed and other information (i.e. the above-mentioned movement information), accurately identify the train, and effectively avoid the misjudgment error of identifying the train by only calculating the movement speed of the mobile phone user.

[0059] Step S206: determining energy-saving strategies for common base stations on the route where the first train is located based on the movement information.

[0060] In the technical solution provided in step S206, there are multiple ways to determine the energy-saving strategy of the ordinary base station in the route where the first train is located based on the mobile information. For example, the energy-saving strategy of the ordinary base station in the route where the first train is located can be determined in the following ways: determine the first sentinel base station in the route of the first train, and determine the downlink ordinary base station set after the first sentinel base station, and determine the running speed of the first train from the mobile information, wherein the first sentinel base station is any sentinel base station in the route of the first train; obtain the first spacing between the first sentinel base station and the first base station, wherein the first base station is any base station in the downlink ordinary base station set; determine the first time between the first sentinel base station and the first base station based on the running speed and the first spacing; determine the energy-saving strategy of the first base station based on the first time. This method adjusts the energy-saving strategy of the base station in advance by calculating the time when the train arrives at the base station, ensuring that the base station can return to normal status in time when the train approaches the base station and provide stable services. It is suitable for scenarios where the train running speed changes greatly, such as morning and evening peak hours in urban rail transit.

[0061] There are multiple ways to implement the energy-saving strategy of the first base station based on the first time, for example: when the first time is less than the first preset time threshold, the energy-saving strategy of the first base station is determined to be the first energy-saving strategy and the second energy-saving strategy, wherein the first energy-saving strategy is used for the first base station to shut down the power amplifier during the symbol period that does not carry data when the user is idle or the service load is less than the first service load threshold, and the second energy-saving strategy is used for the first base station to shut down the preset transmission and receiving channels of the base station during the network light load or no-load time period; when the first time is greater than or equal to the first preset time threshold and less than the second preset time threshold, the energy-saving strategy of the first base station is determined to be the third energy-saving strategy, wherein the third energy-saving strategy is used for the first base station to stop sending or receiving a wireless carrier signal of a preset frequency when the service volume is less than the first preset service volume threshold within a first preset time length; when the first time is greater than or equal to the second preset time threshold, the energy-saving strategy of the first base station is determined to be the fourth energy-saving strategy, wherein the fourth energy-saving strategy is used for the first base station to only support communication functions and the function of waking up the first base station to a normal state when there is no service volume within the second preset time length, and the second preset time length is greater than the first preset time length. By setting different energy-saving strategy thresholds, the energy-saving status of the base station can be managed more finely. This is suitable for scenarios with different time periods and different business needs, such as late night off-peak hours and holidays, and can effectively balance energy saving and service quality.

[0062] The following is a specific embodiment:

[0063] In order to ensure that all common 4 / 5G base stations (non-sentinel base stations) can be awakened in time before the train arrives, and what energy-saving mode to enter after the train leaves, the base station energy-saving system needs to determine how long it will take for the sentinel base station to reach each common base station after it recognizes the train. Therefore, it is necessary to calculate the fastest arrival time difference (i.e. the first time mentioned above) based on the geographical location information of the base station. Figure 7 As shown, a schematic diagram of time difference calculation is provided. First, according to the longitude and latitude (X1, Y1) of the ordinary base station and the longitude and latitude (X2, Y2) of the front and rear sentinel base stations, the station spacing L (i.e., the first spacing mentioned above) between the ordinary base station and the sentinel base station is calculated. The running speed v (determined from the movement information) of the train on the running track (i.e., the first train) on the section is divided by the station spacing L by the running speed v, and the sentinel base station is used as a reference to calculate the shortest time difference (i.e., the first time mentioned above) to each ordinary base station in the uplink and downlink directions, t 上行 {t 上1 , t 上2 ,…t 上n},t 下行 {t 下1 , t 下2 ,…t 下n}, and the shortest time difference between the adjacent sentinel base stations T 上行 and T 下行 After obtaining the above two time difference sets, the base station energy saving system can calculate the time difference between each sentinel base station and any ordinary base station in the uplink and downlink directions of the train dedicated network, and then determine different energy saving methods for different base stations based on the uplink and downlink train positions. The shortest time difference between sentinel base station A and ordinary base station a is as follows: Figure 8 As shown, another schematic diagram of time difference calculation is provided. Table 1 below shows the fastest time difference between each sentinel base station, and Table 2 and Table 3 show the fastest time difference (i.e. the first time) from sentinel base station A to each common base station on the uplink and downlink routes.

[0071] The energy-saving strategies of base stations are as follows:

[0072] Symbol Shutdown (i.e. the first energy-saving strategy mentioned above): During wireless transmission, when the base station detects that the Long Term Evolution (4G) (LTE) / New Radio (5G) (NR) symbol does not carry data, it shuts down the PA in real time (turns off the power amplifier (PA) during the symbol period that does not carry data in real time) to reduce system energy consumption, for example, when the user is inactive, it stops sending data. This can reduce the transmission power and reduce energy consumption.

[0073] Channel Shutdown (i.e. the second energy-saving strategy mentioned above): When the network enters a light-load / no-load period, the base station shuts down or temporarily interrupts a specific channel and shuts down some transmission channels in the cell, thereby reducing transmission power and energy consumption.

[0074] Carrier Shutdown (the third energy-saving strategy mentioned above): When the network enters an idle period, it stops sending or receiving wireless carrier signals of a specific frequency. The carrier is the core element in radio communication, which carries information and is transmitted on electromagnetic waves.

[0075] Deep Sleep (i.e. the fourth energy-saving strategy mentioned above): a long-term energy-saving mode of a base station. A base station that enters deep sleep stops almost all non-essential functions and only retains basic wake-up and communication capabilities.

[0076] Hard Shutdown: All non-emergency functions of the base station are completely shut down, including power.

[0077] The border sentinel base station is the first base station to identify the train entering the area outside the area. It has no prediction of the train approaching time. When it identifies the train approaching, the subsequent ordinary base stations nearby need to wake up quickly to wait for the train to pass to ensure the normal communication needs of train users. Therefore, 4 / 5G ordinary base stations close to the border sentinel base station (for example, ordinary base stations at a preset distance before and after the border sentinel base station) cannot set energy-saving strategies with longer wake-up times, such as deep sleep (i.e., the third energy-saving strategy mentioned above), hard shutdown, and carrier shutdown (i.e., the third energy-saving strategy mentioned above), but should choose channel shutdown (i.e., the second energy-saving strategy mentioned above) and symbol shutdown (i.e., the first energy-saving strategy mentioned above) with short wake-up times.

[0078] For ordinary 4 / 5G base stations (ordinary base stations) near the sentry base stations at the station entrances and exits, since the trains stop at different stations and the stop time varies, the information of incoming trains at some stations as departure stations cannot be estimated, resulting in the time when the train will leave the station cannot be estimated by the train speed and the distance between stations. Therefore, when the sentry base station recognizes that the train is approaching, its subsequent ordinary base stations (for example, ordinary base stations at a preset distance before and after the sentry base stations at the station entrances and exits) need to wake up quickly and wait for the train to pass to ensure the normal communication needs of train users. Channel shutdown (i.e. the second energy-saving strategy mentioned above) and symbol shutdown (i.e. the first energy-saving strategy mentioned above) with short wake-up time should be selected.

[0079] Assuming that the train speed is 300 km / h, the wake-up time of carrier shutdown can usually be set to 30 seconds to 1 minute. Calculated based on the 1-minute wake-up time, the train will run a distance L = 300*(1 / 60) = 5 km.

[0080] Ordinary base stations within 5 km of the border and station exit sentinel base stations do not meet the carrier shutdown wake-up conditions and cannot be set to a carrier shutdown energy-saving strategy. It is necessary to set a channel shutdown strategy with a wake-up time of seconds and a symbol shutdown strategy with a wake-up time of milliseconds.

[0081] Similarly, assuming the train speed is 300 km / h, the wake-up time of deep sleep is usually 2 to 3 minutes. Based on the 3-minute wake-up time, the train will run a distance of L = 300*(3 / 60) = 15 km. Therefore, ordinary base stations between 5 km and 15 km from the border and station exit sentry base stations can be set to the carrier shutdown strategy, while ordinary base stations greater than 15 km from the border and station exit sentry base stations can be set to the deep sleep energy-saving strategy.

[0082] For ordinary 4 / 5G base stations (ordinary base stations) in other areas outside the above two areas, all are in operation. The shortest time for a train to reach this station from the front sentinel base station can be estimated by the station spacing and the fastest speed of the train. Therefore, a more energy-saving but relatively longer wake-up time energy-saving method can be selected, such as carrier shutdown and deep sleep. Hard shutdown is not recommended during the day.

[0083] In another optional embodiment, the energy saving strategy of the common base station may also be determined in the following manner:

[0084] ①When t1<T 唤醒_载波关断 (That is, when the first time is less than the first preset time threshold, T 唤醒_载波关断 is the first preset time threshold)

[0085] Then, the common base station needs to set symbol shutoff + channel shutoff (i.e. the first energy-saving strategy and the second energy-saving strategy mentioned above);

[0086] ②When T 唤醒_载波关断<t1<T 唤醒_深度休眠 (That is, in the case where the first time is greater than or equal to the first preset time threshold and less than the second preset time threshold)

[0087] Then, the common base station needs to be set to carrier off (i.e. the third energy saving strategy mentioned above);

[0088] ③When T 唤醒_深度休眠 >t1

[0089] Then, the common base station needs to be set to deep sleep (ie the fourth energy-saving strategy mentioned above).

[0090] After the energy-saving strategy of the common base station is set in the above steps, the base station energy-saving system generates and sends an instruction to wake up the energy-saving base station when the train is about to arrive, and adjusts the energy-saving strategy of the first base station to the second energy-saving strategy, for example, in the following ways:

[0091] Determine the energy-saving strategy adopted by the first base station; when the energy-saving strategy adopted by the first base station is the third energy-saving strategy, determine the first remaining arrival time based on the first time and the wake-up time of the third energy-saving strategy; when the first remaining arrival time is equal to the wake-up time of the third energy-saving strategy, adjust the energy-saving strategy of the first base station to the second energy-saving strategy; when the energy-saving strategy adopted by the first base station is the fourth energy-saving strategy, determine the second remaining arrival time based on the first time and the wake-up time of the fourth energy-saving strategy; when the second remaining arrival time is equal to the wake-up time of the fourth energy-saving strategy, adjust the energy-saving strategy of the first base station to the second energy-saving strategy. By calculating the remaining arrival time, it can ensure that the base station can return to normal status in time before the train arrives. It is suitable for scenarios where the train running time is relatively fixed and predictable, such as the operation schedule of high-speed railways, and can provide more stable and reliable communication services.

[0092] The following is a specific embodiment:

[0093] Principles for issuing wake-up instructions for carrier shutdown and deep sleep energy-saving strategies: Due to carrier shutdown and deep sleep energy-saving, ordinary base stations completely lose their communication functions and the wake-up time is relatively long. Therefore, the base station energy-saving platform calculates the fastest time point for the train in front of each 4 / 5G base station along the line to arrive at the base station through the train information reported by the sentinel base station, and then generates the wake-up instructions for the corresponding time points in combination with the wake-up time required for different energy-saving strategies, generates the instruction stack in chronological order, and issues the wake-up instructions before the estimated train arrives. The base station enters the channel shutdown energy-saving state, and then wakes up according to the principles for issuing wake-up instructions for the channel shutdown energy-saving strategy. Specifically:

[0094] like Fig. 9As shown, a train operation schematic diagram is provided, where sentinel base station A identifies the first train, and based on the current time and the fastest arrival time (i.e. the above-mentioned first time), when the first remaining arrival time / the second remaining arrival time is equal to the wake-up time of the third energy-saving strategy / the wake-up time of the fourth energy-saving strategy, the energy-saving strategy of the first base station is adjusted to the second energy-saving strategy, and when the time is the sum of the current time and the fastest arrival time, the base station enters the channel shutdown energy-saving state, and then wakes up according to the principle of issuing the channel shutdown energy-saving strategy wake-up instruction.

[0095] When the energy-saving strategy adopted by the first base station is the second energy-saving strategy, the network load of the first base station is determined; when the network load of the first base station is greater than the first preset capacity threshold, the first base station is adjusted to a normal state. This method can restore the normal state in time when the network load is high by monitoring the network load. It is suitable for scenarios with large fluctuations in network load, such as rush hour on subway platforms, and can ensure the stability and reliability of the communication network.

[0096] The following is a specific embodiment:

[0097] Channel shutdown energy-saving strategy wake-up command issuance principle: Since channel shutdown retains the basic communication function of the base station and a certain network capacity, and the wake-up time is in seconds, the wake-up of the cell (ordinary base station) for channel shutdown energy saving does not use the time estimation method, but uses the wake-up method of the network load of the base station ahead not meeting the current user demand, and the instantaneous wake-up method of insufficient capacity when the train user accesses this station.

[0098] For example, Fig.10 As shown, another schematic diagram of the base station wake-up process is provided:

[0099] 1) When a train user accesses sentry base station (sentry station) A, the overall network load of the base station is low (that is, when the network load of the first base station is less than or equal to the first preset capacity threshold), the base station energy-saving platform performs capacity estimation and determines that the capacity of subsequent energy-saving base stations using channel shutdown still meets the capacity requirements, then the ordinary base station a keeps the channel shut down.

[0100] 2) When the train user accesses sentinel base station A, the overall network load of the base station is relatively high (that is, when the network load of the first base station is greater than the first preset capacity threshold), the base station energy-saving platform performs capacity estimation and determines that the capacity of the subsequent energy-saving base stations using channel shutdown cannot meet the capacity requirements. In this case, the ordinary base station a turns off the channel shutdown before the train arrives, wakes up all the functions of the base station, and waits until the train passes.

[0101] When the train is connected to the ordinary base station a, the number of business users continues to increase. At this time, the channel shutdown energy-saving strategy can no longer meet the business needs. The ordinary base station immediately shuts down the channel energy saving and wakes up in seconds to ensure the network capacity requirements. The subsequent base station uses method 2) to shut down the channel shutdown energy-saving strategy.

[0102] When the train is identified to be far away from the ordinary base station, the base station energy-saving system generates and issues energy-saving instructions to make the ordinary base station re-enter the energy-saving state, for example, in the following ways:

[0103] When the first base station adopting the second energy-saving strategy identifies that the first train leaves the first base station, an energy-saving instruction is issued to instruct the first base station to end the normal state. When the first base station adopting the third energy-saving strategy or the fourth energy-saving strategy identifies that the first train leaves the first base station: an energy-saving instruction is issued to instruct the first base station to adopt the second energy-saving strategy; the uplink arrival time and the downlink arrival time of the up train and the down train of the first train to arrive at the first base station are calculated; when the uplink arrival time or the downlink arrival time is less than the wake-up time of the third energy-saving strategy, an energy-saving instruction is issued to instruct the first base station to adopt the second energy-saving strategy; when the uplink arrival time or the downlink arrival time is greater than or equal to the wake-up time of the third energy-saving strategy, an energy-saving instruction is issued to instruct the first base station to adopt the third energy-saving strategy; when the uplink arrival time or the downlink arrival time is greater than or equal to the wake-up time of the fourth energy-saving strategy, an energy-saving instruction is issued to instruct the first base station to adopt the fourth energy-saving strategy, wherein the wake-up time of the third energy-saving strategy is less than the wake-up time of the fourth energy-saving strategy. This method can more reasonably adjust the energy-saving strategy of the base station by comprehensively considering the uplink and downlink arrival times of the train. It is suitable for scenarios with high train operation density and bidirectional operation, such as busy periods of subway lines, and can effectively improve the overall energy efficiency of the system.

[0104] The following is a specific embodiment:

[0105] Since the estimated time for when the train enters the coverage area of ​​the base station in the above steps is the fastest arrival time, and the actual arrival time is often longer than the estimated time and there is uncertainty. Therefore, the estimated time cannot be used to determine the time when the train leaves the coverage area of ​​this station. Therefore, the departure time needs to be determined according to the following situations.

[0106] The first case, such as Fig.11As shown, a 4G single-cell downlink physical resource block (PRB) average utilization (10-second tracking) graph is provided, and judgments are made based on the sudden increase or decrease in the number of users of the sentinel base station. Under normal circumstances, when a train enters a 4 / 5G coverage area, due to the large number of users in the train, according to the business concurrency probability of 30% (industry experience value), when a train with a 30% occupancy rate passes by, the number of users connected to the cell (base station) will increase by more than 20 people at the same time. Therefore, the departure of the train can be judged by judging the sudden drop in the number of connected users or the sudden drop in PRB utilization, and energy-saving instructions can be issued to end the normal state of ordinary base stations. As shown in FIG. Fig.11 As shown, the peak is the sudden increase in user and PRB utilization when the train passes by, and the PRB utilization drops suddenly to a lower level after leaving.

[0107] In the second case, since the train runs at a low passenger flow, it cannot show the trend of sudden increase or decrease in user or PRB utilization. At this time, the next sentinel base station detects the arrival of the train and determines that the train has left the two-sentinel section, thereby compensating for the deficiency of such special cases and issuing energy-saving instructions to end the normal state of the ordinary base station.

[0108] To sum up, they can be divided into the following categories:

[0109] like Fig.12 , provides a schematic diagram of the train running process, in which each common base station in the process of train A from entering to leaving ends the normal state in the following manner:

[0110] The first type is that the initial energy-saving strategy is the channel shutoff strategy. After recognizing the departure of the train, it immediately switches to the channel shutoff strategy, ending the normal state and entering the energy-saving state.

[0111] The second type, the initial energy saving is the carrier shutdown or deep sleep strategy. After recognizing the departure of the train, the channel shutdown strategy is first entered, and the train departure information is fed back to the base station energy saving system. At this time, the base station energy saving system performs a comprehensive judgment on the uplink and downlink trains in the initial energy saving state machine, and respectively calculates the maximum arrival time of the two trains (i.e. the above-mentioned uplink arrival time and downlink arrival time) for the positions of the nearest uplink and downlink trains. If the fastest arrival time of the train is greater than or equal to the wake-up time of deep sleep (i.e. the wake-up time of the above-mentioned fourth energy saving strategy), an energy saving instruction (deep sleep instruction) is issued, and it is set to the deep sleep strategy (i.e. the above-mentioned fourth energy saving strategy); if the fastest arrival time of the train is less than the wake-up time of deep sleep (i.e. the wake-up time of the above-mentioned third energy saving strategy), but greater than the wake-up time of carrier shutdown (i.e. the wake-up time of the above-mentioned fourth energy saving strategy), an energy saving instruction (carrier shutdown instruction) is issued, and it is set to the carrier shutdown strategy (i.e. the above-mentioned third energy saving strategy); if the fastest arrival time does not meet the wake-up time of carrier shutdown, it enters the on-off shutdown and wakes up according to the on-off shutdown wake-up strategy.

[0112] The method in the embodiment of the present application introduces 5G-A interawareness technology through the above steps, realizes accurate identification of rail trains, and through the characteristics of train operation, by selecting three types of mandatory sentinel base stations, namely, border sentinel base stations, intersection sentinel base stations, and station entrance and exit sentinel base stations, the location information of on-rail trains entering a certain section can be fully grasped, thereby effectively solving the problem of misjudgment of the position of running trains in the prior art. By calculating the maximum arrival time of the train based on the station spacing between the sentinel base station and the ordinary base station, and then according to the characteristics that cannot be determined based on the time when the train enters the border and leaves the station, the border sentinel base station and the station sentinel base station are used as reference points, and the shortest time for the train to reach the subsequent base station after passing through the two reference points is calculated, so that different energy-saving strategies are set for ordinary stations at different locations, so as to achieve the energy-saving effect to the greatest extent, and at the same time, it can ensure that the network capabilities of train users passing through each 4 / 5G base station meet user needs. The energy-saving efficiency is maximized by adopting the method of deep sleep / carrier shutdown and channel shutdown step-by-step wake-up. At a reasonable time, the deep sleeping base station is first awakened to the channel shutdown energy-saving mode, and then the step-by-step awakening method is used to determine whether to turn off the channel shutdown based on the load situation of the base station ahead. This not only ensures the train users' needs for Internet access and phone calls, but also ensures maximum energy saving.

[0113] The present application embodiment provides a flow chart of another method for adjusting a base station energy saving strategy, such as Figure 3 As shown,

[0114] Through the first module, three types of base stations are selected as sentinel base stations: entry and exit sentinel base stations, boundary sentinel base stations, and fork sentinel base stations. Then, through the second module, the estimated shortest time difference for the train to reach each base station between two sentinel base stations is calculated based on the geographical location of the base station. The sentinel base station is used as a reference to calculate the shortest time difference from it to each ordinary base station in the uplink and downlink directions. The time difference from each sentinel base station to any ordinary base station in the uplink and downlink directions of the private network (private network for the train route) is calculated (i.e. the first time mentioned above), and the sum of the start-up time of different energy-saving modes is obtained to formulate and issue energy-saving start and stop instructions to ordinary base stations; then it is input into the third module to set the initial energy-saving plan for the private network 4 / 5G base station (i.e. the above-mentioned energy-saving strategy). For ordinary base station equipment near the station entrances and exits and border sentry base stations, the channel and symbol are turned off, and for ordinary base stations in other areas, they are set to carrier off and deep sleep; finally, through the fourth module, the energy-saving system sends a working state (i.e. the normal state mentioned above) / energy-saving state instruction, and instructs the base station to enter the working state (normal state) based on the channel shutoff energy-saving cell wake-up instruction principle and the carrier shutoff and deep sleep and energy-saving sleep cell wake-up instruction principle; based on the judgment of the sudden increase and decrease in the number of users of the sentry base station and the comprehensive judgment of the initial energy-saving state uplink and downlink trains, the base station is instructed to enter the energy-saving state. The specific implementation process has been described in detail in the above embodiments and will not be repeated here.

[0115] The present application embodiment provides a schematic diagram of a structure of a device for adjusting a base station energy saving strategy, such as Fig.13 As shown,

[0116] The first determination module 1302 is used to determine a sentinel base station from all base stations passed by the train route, wherein the sentinel base station is used to sense the approach or departure of the train, and base stations other than the sentinel base station on the train route are determined as ordinary base stations.
