Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and more specifically, to a high-speed rail network service energy-saving system and method. Background Art

[0002] With the rapid development of economy and technology, people's travel methods have become more diverse. High-speed rail has become the preferred means of transportation for more and more people due to its fast and convenient characteristics. On high-speed rail, passengers' demands for the network are becoming more and more abundant. Whether browsing the web, watching videos or making video calls, high-quality network support is required. Therefore, the network quality on the high-speed rail directly affects the passengers' satisfaction evaluation of the operator's network. At present, 5G base stations mainly adopt the fixed-time energy-saving method, that is, energy-saving measures are implemented through pre-set energy-saving time periods. Although this method can reduce energy consumption to a certain extent, it has obvious shortcomings in high-speed mobile scenarios. Specifically, during the operation of high-speed rail, user access needs fluctuate greatly with changes in time and location. In certain time periods, especially at night or during non-peak hours, the number of users on the high-speed rail is extremely small, but the base station is still in normal operation, resulting in unnecessary energy consumption; the fixed energy-saving time period cannot adapt to the dynamic changes in the operation of the high-speed rail, which may lead to a decline in network service quality during the period when user demand is high. Therefore, in order to find a balance between ensuring customer perception and improving energy-saving efficiency, a base station energy-saving solution that can dynamically and accurately identify the operation status of the high-speed rail is needed.

[0020] 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.

[0021] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of the present application 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.

[0022] In order to better understand the embodiments of the present application, some nouns or terms that appear in the description of the embodiments of the present application are first translated and explained as follows:

[0023] Symbol shutdown: An energy-saving technology mainly used in wireless communication systems, especially LTE (Long Term Evolution) and 5G networks. The basic principle of this technology is to temporarily shut down some or all transmission resources when there is no data transmission demand, including reducing the transmission power or completely stopping the signal transmission in certain symbol periods, so as to save energy.

[0024] Channel shutdown: An energy-saving technology widely used in modern wireless communication networks. The core concept of this technology is to temporarily shut down some physical antenna channels or logical channels when the network traffic is low or there is no data transmission demand, thereby reducing the power consumption of the base station. Specifically: the base station continuously monitors the traffic on each channel and evaluates the number of channels currently required based on the monitoring results. When it is detected that one or some channels are in a low-load state for a long time, the system will automatically shut down these channels until the traffic increases to the point where they need to be activated.

[0025] Carrier shutdown: An energy-saving technology in which the system continuously monitors traffic in the network and identifies which carriers have low utilization. Based on the results of traffic monitoring, the network automatically decides whether to shut down one or more carriers. When traffic increases to a preset threshold, the system automatically reactivates the previously shut down carriers to ensure that user service quality is not affected.

[0026] Example 1

[0027] According to the embodiment of the present application, a high-speed rail network service energy-saving system is first provided, such as Figure 1 As shown, the system at least includes: a plurality of 5G base stations that are sequentially adjacent to each other along the target high-speed railway line, and each 5G base station manages a target cell that provides network services for a target terminal on the high-speed railway of the target high-speed railway line. Among them:

[0028] The 5G base stations at the head and tail ends of the multiple 5G base stations are configured as sentinel base stations 111 and 112, and the other 5G base stations are configured as intermediate base stations 12 (1~m). The distance between the sentinel base station on the starting point side of the target high-speed railway line and the starting point of the target high-speed railway line is not less than the acceleration distance of the high-speed railway from stationary to rated speed, and the distance between the sentinel base station on the terminal side of the target high-speed railway line and the terminal of the target high-speed railway line is not less than the deceleration distance of the high-speed railway from rated speed to stationary.

[0029] Each sentinel base station is in working mode during the first preset time period of each day, and in sleep mode at other times. Each intermediate base station is in working mode during the second preset time period of each day, and in sleep mode at other times. The start time of the first preset time period is earlier than the start time of the second preset time period, and the end time of the first preset time period is the same as that of the second preset time period.

[0030] During the difference between the first preset time period and the second preset time period, the sentinel base station is used to notify each intermediate base station to switch from the sleep mode to the working mode in advance when detecting that the target terminal accesses the sentinel base station.

[0031] The following describes the functions of each module in the high-speed rail network service energy-saving system in conjunction with the specific implementation process.

[0032] In order to solve the technical problem that the 5G base station sleep time is fixed in the relevant high-speed rail network service scenario and cannot guarantee the perception of early-shift high-speed rail users, this application first proposes a high-speed rail network service energy-saving system, the working process of which is as follows:

[0033] Multiple adjacent 5G base stations are arranged in sequence along the target high-speed rail line, and each 5G base station manages a target cell that provides network services to the target terminal on the high-speed rail of the target high-speed rail line.

[0034] Optionally, since the high-speed train runs at a very high speed, it means that the train will quickly pass through the network coverage area in a short time, which requires that the network switching must be fast and accurate. The wireless signal will experience attenuation during the propagation process. As the distance increases, the signal strength will drop significantly. To reduce these effects, the base station can be set as follows: Among multiple 5G base stations, only adjacent 5G base stations communicate with each other. Among multiple target cells corresponding to multiple 5G base stations, only the target cells corresponding to adjacent 5G base stations are configured as switchable neighboring cells.

[0035] Among them, the 5G base stations at the head and tail ends of multiple 5G base stations are configured as sentinel base stations, and other 5G base stations are configured as intermediate base stations. The distance between the sentinel base station on the starting point side of the target high-speed rail line and the starting point of the target high-speed rail line is not less than the acceleration distance of the high-speed rail from stationary to rated speed, and the distance between the sentinel base station on the terminal side of the target high-speed rail line and the terminal of the target high-speed rail line is not less than the deceleration distance of the high-speed rail from rated speed to stationary.

[0036] According to the relevant regulations on acceleration and deceleration of high-speed trains, the operating speed of high-speed trains reaches 350km / h, and the distance required for acceleration and deceleration during the operation of high-speed trains is 35km; the high-speed train operation range is divided into acceleration section, uniform speed section, and deceleration section; uniform acceleration or uniform deceleration is performed when starting from the high-speed train station or about to enter the station. Use the average velocity displacement formula and acceleration displacement formula to calculate and find the location of the sentinel base station; the following example takes the acceleration movement of the high-speed train leaving the station as an example:

[0037] Among them, according to the relevant regulations on acceleration and deceleration of high-speed trains, the high-speed train goes from rest to the maximum speed V c (350km / h), the required acceleration distance is S (17.5km), the initial speed is V0, the acceleration is a, and the running time is t, then according to the speed formula: V c =V0+at, we can get:

[0038] at=V c -V0=350km / h

[0039] According to the displacement formula:

[0040]

[0041] Substituting at into the formula, we get:

[0042] That is, t = 6 minutes

[0043] According to the formula for uniformly accelerated motion, it can be calculated that the high-speed train has run 400 meters from the time it leaves the station to the time its speed reaches 80km / h. Therefore, according to the requirements of this example, the sentinel base station should be set up 400 meters and 400 meters away from the high-speed railway station, which is the starting point of the target high-speed railway line.

[0044] Each sentinel base station is in working mode during the first preset time period of each day, and in sleep mode at other times. Each intermediate base station is in working mode during the second preset time period of each day, and in sleep mode at other times. The start time of the first preset time period is earlier than the start time of the second preset time period, and the end time of the first preset time period is the same as that of the second preset time period.

[0045] For example, the sleep setting time of the sentinel base station, that is, the time outside the first preset time period, is slightly different from the sleep setting time of other base stations on the high-speed rail line. For example, the sleep time of general base stations on the high-speed rail line is from 23:30 to 8:00 the next day, and the sleep time of the sentinel base station can be set from 23:30 to 6:30 the next day; during the time period from 6:30 to 8:00, once the sentinel base station identifies the user terminal on the high-speed rail, it will wake up other intermediate base stations that are still in sleep mode through the sentinel base station to ensure the communication use of users on the early high-speed rail trains.

[0046] Optionally, the sleep mode of the sentinel base station is a symbol-off energy-saving mode; and the sleep mode of the intermediate base station is a carrier-off energy-saving mode.

[0047] In the symbol-off energy-saving mode, the base station will not be completely shut down, but will retain basic network service capabilities. Specifically, when the base station adopts the symbol-off energy-saving mode, it will shut down some symbols that are not needed for data transmission in each time slot, while ensuring that key control information symbols (such as synchronization signals, reference time signals, etc.) are still sent to maintain the coverage and access capabilities of the cell. In this way, even in the symbol-off mode, the base station can still receive user access requests, perform signaling interactions, and quickly return to normal working state upon receiving a data transmission request to provide data transmission services.

[0048] The carrier shutdown energy-saving mode will also be designed to be carried out without affecting the user experience. That is, while shutting down the energy-saving carrier, it ensures that other available carriers or carriers of neighboring base stations provide services to ensure network continuity and service quality, but no communication services will be provided for terminals on the high-speed rail.

[0049] Optionally, within the difference time period between the first preset time period and the second preset time period, the sentinel base station is used to respond to the access request of any terminal, determine the moving speed of the terminal, and when the moving speed is greater than a preset speed threshold, determine that the terminal is a target terminal on the high-speed rail of the target high-speed rail line, access the target terminal, and notify each intermediate base station to switch from sleep mode to working mode in advance.

[0050] The preset speed threshold can be based on the current speed limit standard, that is, 80km / h can be taken as the preset speed threshold. The sentinel base station identifies the terminal with a moving speed greater than this speed as the target terminal on the high-speed rail. However, in special circumstances, the preset speed threshold can also be dynamically adjusted through real-time data analysis by the network monitoring center to adapt to changes in moving speed caused by seasonality or special events.

[0051] Among them, the configuration of the sentinel base station can also deploy additional high-precision clock synchronization devices to ensure the accuracy of speed identification and the timeliness of network provision.

[0052] In addition to the solution based on speed recognition, it is also possible to consider combining multi-dimensional data detection, for example: using GPS positioning data, combined with the high-speed rail train schedule, to predict the location and operation status of the high-speed rail train. When the sentinel base station detects a user access request in a specific geographical area (such as near a high-speed rail station), combined with the current time, it can be preliminarily determined that the user terminal is a target terminal on the high-speed rail; it is also possible to analyze historical data to identify the typical behavior patterns of high-speed rail users, such as users who frequently use high-traffic services at specific times (such as morning peak hours and evening peak hours) and in specific locations (such as along the high-speed rail line). When user behaviors that match these patterns are detected, it can assist in determining that the user terminal is a target terminal on the high-speed rail; it is also possible to use historical data and machine learning algorithms to predict the operating time and line usage of high-speed rail, and establish a prediction model that analyzes past high-speed rail operating modes, passenger flow, holidays, weather, etc., and predicts future high-speed rail operating plans. In this way, even without speed information, the base station can quickly adjust to the working mode; it is also possible to combine multiple technologies to form a composite recognition system, for example, using speed recognition as the primary trigger, and then confirming it again through the prediction model to further improve the accuracy of recognition.

[0053] Other neighboring cell switching relationships between sentinel base stations and intermediate base stations can also take into account terrain and building shielding factors to optimize signal coverage.

[0054] As an optional implementation, during the difference between the first preset time period and the second preset time period, when the sentinel base station detects that the target terminal accesses the sentinel base station, it sends a wake-up notification message to the intermediate base station adjacent to the sentinel base station, wherein the wake-up notification message is used to instruct the 5G base station to switch from sleep mode to working mode. Each intermediate base station is used to send a wake-up notification message to the 5G base station on the other side adjacent to itself after receiving the wake-up notification message sent by the 5G base station on one side adjacent to itself, and detect its own working state, and if it is in sleep mode, switch from sleep mode to working mode; in particular, if it is in working mode, keep the working mode unchanged, that is, after an intermediate base station has been awakened to working mode by the wake-up notification message on one side, if the intermediate base station on the other side also sends a wake-up notification message to the base station, the intermediate base station continues to remain in working mode. This is because the high-speed rail line is used for bidirectional high-speed rail operation, and wake-up notification messages may be sent from each side of the intermediate base station.

[0055] It should be noted that, since the sentinel base station can detect whether there is a need for terminal access, the last intermediate base station may not send the wake-up notification information to the sentinel base station on the end point side after receiving the wake-up notification information.

[0056] Optionally, within a first preset time period, each sentinel base station is used to switch from working mode to sleep mode from the moment it enters working mode when the duration of its state without target terminal access exceeds the first preset duration, and switch from sleep mode to working mode when the target terminal is detected to access the sentinel base station again, and re-send wake-up notification information to the intermediate base station adjacent to the sentinel base station. Within the first preset time period, each intermediate base station is used to switch from working mode to sleep mode from the moment it enters working mode when the duration of its state without target terminal access exceeds the second preset duration, and after receiving the wake-up notification information sent by the 5G base station adjacent to itself, switch from sleep mode to working mode, and send wake-up notification information to the 5G base station adjacent to itself on the other side, wherein the second preset duration is not less than the time it takes for the high-speed rail to travel from the starting point of the target high-speed rail line to the intermediate base station, and is not less than the time it takes for the high-speed rail to travel from the intermediate base station to the end point of the target high-speed rail line.

[0057] Specifically, during the first preset time period, each sentinel base station is generally in working mode, but during the first preset time period, there may be a situation where there is no terminal access demand for a long time, and there is no need to provide communication services at this time. In this case, if it is always in working mode, unnecessary power consumption will be generated. Therefore, in order to further save energy, each sentinel base station can be switched between working mode and sleep mode during the first preset time period, rather than always being in working mode. For switching in this case, a first preset duration can be specified. Each sentinel base station switches from working mode to sleep mode from the moment it enters working mode when the duration of its being in a state without target terminal access exceeds the first preset duration, and switches from sleep mode to working mode when the target terminal is detected to access the sentinel base station again, and re-sends wake-up notification information to the intermediate base stations adjacent to the sentinel base station. For each intermediate base station, the same switching mode can be adopted, but unlike the first preset duration, a second preset duration is adopted. The second preset duration is set to be no less than the duration of the high-speed rail from the starting point of the target high-speed rail line to the intermediate base station, and no less than the duration of the high-speed rail from the intermediate base station to the end point of the target high-speed rail line. For example, in real life, a high-speed rail line is used for two-way travel of high-speed rail. Assuming the starting point is A and the end point is B, the intermediate base station will receive wake-up notification information from A to B, and will also receive wake-up notification information from B to A. At this time, it is necessary to set the second preset duration to be no less than the duration of the high-speed rail from A to the intermediate base station and the duration of the high-speed rail from B to the intermediate base station.

[0058] As an optional implementation, each intermediate base station is also used to switch from sleep mode to working mode in response to a wake-up notification message from the base station control center when it is in sleep mode, and send a wake-up notification message to the 5G base stations on both sides adjacent to itself. For example, in the case of a high-speed train delay, there will be a period of time when there is no terminal access that exceeds the second preset period. At this time, the intermediate base station can receive the wake-up notification message from the base station control center, and switch to working mode to provide communication services for the terminal.

[0059] In order to further save energy, the energy management of the sentinel base stations can also be adjusted, for example, using renewable energy sources such as solar energy and wind energy to further improve the energy conservation and emission reduction effects.

[0060] In the embodiment of the present application, sentinel base stations are set at both ends of the high-speed rail line, and intermediate base stations are set at other locations. The sentinel base stations are located at the key positions of high-speed rail acceleration and deceleration to ensure that stable network connection can be obtained even in the stage where the speed of high-speed rail trains changes greatly; the sentinel base station works in the first preset time period of the day, and the intermediate base station works in the second preset time period. The end time of the two time periods is the same, but the working time of the sentinel base station starts earlier than the intermediate base station; this can ensure that preparations are made before the peak period of network demand, while reducing energy consumption during the off-peak period; in the difference time period between the first preset time period and the second preset time period, if the sentinel base station detects that the target terminal is accessed, it will notify all intermediate base stations to switch from sleep mode to working mode in advance. This mechanism can ensure the immediate availability of network services while avoiding unnecessary energy waste, thereby solving the technical problem that the sleep time of 5G base stations in related high-speed rail network service scenarios is fixed and cannot guarantee the perception of early high-speed rail users.

[0061] Example 2

[0062] On the basis of the high-speed rail network service energy-saving system provided in Example 1, the embodiment of the present application also provides a high-speed rail network service energy-saving method, which is applied to any base station of multiple 5G base stations that are adjacent in sequence along the target high-speed rail line, wherein each 5G base station manages a target cell that provides network services for the target terminal on the high-speed rail of the target high-speed rail line, and the 5G base stations at the head and tail ends of the multiple 5G base stations are configured as sentinel base stations, and the other 5G base stations are configured as intermediate base stations. The distance between the sentinel base station on the starting point side of the target high-speed rail line and the starting point of the target high-speed rail line is not less than the acceleration distance of the high-speed rail from static to rated speed, and the distance between the sentinel base station on the terminal side of the target high-speed rail line and the terminal of the target high-speed rail line is not less than the deceleration distance of the high-speed rail from rated speed to static. 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 the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.

[0063] Figure 2 is a flow chart of a high-speed rail network service energy-saving method provided according to an embodiment of the present application, such as Figure 2 As shown, the method comprises the following steps:

[0064] Step S202: When the sentinel base station is a sentinel base station, the sentinel base station operates in working mode during the first preset time period of the day and in sleep mode at other times; when the target terminal is detected to access the sentinel base station during the difference time period between the first preset time period and the second preset time period, each intermediate base station is notified to switch from sleep mode to working mode in advance, wherein the start time of the first preset time period is earlier than the start time of the second preset time period, and the end time of the first preset time period is the same as the end time of the second preset time period;

[0065] Step S204, when it is an intermediate base station, it runs in working mode during the second preset time period of the day, and runs in sleep mode at other times; within the difference time period between the first preset time period and the second preset time period, in response to the wake-up notification information from the sentinel base station, it switches from sleep mode to working mode in advance.

[0066] The following describes the various steps of the high-speed rail network service energy-saving method in conjunction with the specific implementation process.

[0067] There are multiple 5G base stations adjacent to each other along the target high-speed rail line, and each 5G base station manages a target cell that provides network services to the target terminal on the high-speed rail of the target high-speed rail line.

[0068] Optionally, since the high-speed train runs at a very high speed, it means that the high-speed train will quickly pass through the network coverage area in a short time, which requires that the network switching must be fast and accurate. The wireless signal will experience attenuation during the propagation process. As the distance increases, the signal strength will drop significantly. To reduce these impacts, the base station can be set as follows: Among multiple 5G base stations, only adjacent 5G base stations communicate with each other, and among multiple target cells corresponding to multiple 5G base stations, only the target cells corresponding to adjacent 5G base stations are configured as switchable neighboring cells.

[0069] Among them, the 5G base stations at the head and tail ends of multiple 5G base stations are configured as sentinel base stations, and other 5G base stations are configured as intermediate base stations. The distance between the sentinel base station on the starting point side of the target high-speed rail line and the starting point of the target high-speed rail line is not less than the acceleration distance of the high-speed rail from stationary to rated speed, and the distance between the sentinel base station on the terminal side of the target high-speed rail line and the terminal of the target high-speed rail line is not less than the deceleration distance of the high-speed rail from rated speed to stationary.

[0070] Each sentinel base station is in working mode during the first preset time period of each day, and in sleep mode at other times. Each intermediate base station is in working mode during the second preset time period of each day, and in sleep mode at other times. The start time of the first preset time period is earlier than the start time of the second preset time period, and the end time of the first preset time period is the same as that of the second preset time period.

[0071] Optionally, the sleep mode of the sentinel base station is a symbol-off energy-saving mode; and the sleep mode of the intermediate base station is a carrier-off energy-saving mode.

[0072] In the symbol-off energy-saving mode, the base station will not be completely shut down, but retains basic network service capabilities. Specifically, when the base station adopts the symbol-off energy-saving mode, it will shut down some symbols that are not needed for data transmission in each time slot, while ensuring that key control information symbols (such as synchronization signals, reference time signals, etc.) are still sent to maintain the coverage and access capabilities of the cell. In this way, even in the symbol-off state, the base station can still receive user access requests, perform signaling interactions, and quickly return to normal working state upon receiving a data transmission request to provide data transmission services.

[0073] The carrier shutdown energy-saving mode will also be designed to be carried out without affecting the user experience. That is, while shutting down the energy-saving carrier, other available carriers or carriers of neighboring base stations are ensured to provide services to ensure network continuity and service quality.

[0074] Optionally, within the difference time period between the first preset time period and the second preset time period, the sentinel base station is used to respond to the access request of any terminal, determine the moving speed of the terminal, and when the moving speed is greater than a preset speed threshold, determine that the terminal is a target terminal on the high-speed rail of the target high-speed rail line, access the target terminal, and notify each intermediate base station to switch from sleep mode to working mode in advance.

[0075] The preset speed threshold can be based on the current speed limit standard, that is, 80 kilometers per hour can be taken as the preset speed threshold. The sentinel base station identifies the terminal with a moving speed greater than this speed as the target terminal on the high-speed rail. However, in special circumstances, the preset speed threshold can also be dynamically adjusted through real-time data analysis by the network monitoring center to adapt to changes in moving speed caused by seasonality or special events.

[0076] In addition to the solution based on speed recognition, it is also possible to consider combining multi-dimensional data detection, for example: using GPS positioning data, combined with the high-speed rail train schedule, to predict the location and operation status of the high-speed rail train. When the sentinel base station detects a user access request in a specific geographical area (such as near a high-speed rail station), combined with the current time, it can be preliminarily determined that the user terminal is a target terminal on the high-speed rail; it is also possible to analyze historical data to identify the typical behavior patterns of high-speed rail users, such as users who frequently use high-traffic services at specific times (such as morning peak hours and evening peak hours) and in specific locations (such as along the high-speed rail line). When user behaviors that match these patterns are detected, it can assist in determining that the user terminal is a target terminal on the high-speed rail; it is also possible to use historical data and machine learning algorithms to predict the operating time and line usage of high-speed rail, and establish a prediction model that analyzes past high-speed rail operating modes, passenger flow, holidays, weather, etc., and predicts future high-speed rail operating plans. In this way, even without speed information, the base station can quickly adjust to the working mode; it is also possible to combine multiple technologies to form a composite recognition system, for example, using speed recognition as the primary trigger, and then confirming it again through the prediction model to further improve the accuracy of recognition.

[0077] Other neighboring cell switching relationships between sentinel base stations and intermediate base stations can also take into account terrain and building shielding factors to optimize signal coverage.

[0078] As an optional implementation, during the difference between the first preset time period and the second preset time period, when the sentinel base station detects that the target terminal has accessed the sentinel base station, it sends a wake-up notification message to the intermediate base station adjacent to the sentinel base station, wherein the wake-up notification message is used to instruct the 5G base station to switch from sleep mode to working mode; each intermediate base station is used to send a wake-up notification message to the 5G base station adjacent to itself on the other side after receiving the wake-up notification message sent by the 5G base station adjacent to itself, and detect its own working status, if it is in sleep mode, switch from sleep mode to working mode, if it is in working mode, keep the working mode unchanged.

[0079] Optionally, within a first preset time period, each sentinel base station is used to switch from working mode to sleep mode from the moment it enters working mode when the duration of its state without target terminal access exceeds the first preset duration, and switch from sleep mode to working mode when the target terminal is detected to access the sentinel base station again, and re-send wake-up notification information to the intermediate base station adjacent to the sentinel base station. Within the first preset time period, each intermediate base station is used to switch from working mode to sleep mode from the moment it enters working mode when the duration of its state without target terminal access exceeds the second preset duration, and after receiving the wake-up notification information sent by the 5G base station adjacent to itself, switch from sleep mode to working mode, and send wake-up notification information to the 5G base station adjacent to itself on the other side, wherein the second preset duration is not less than the time it takes for the high-speed rail to travel from the starting point of the target high-speed rail line to the intermediate base station, and is not less than the time it takes for the high-speed rail to travel from the intermediate base station to the end point of the target high-speed rail line.

[0080] Specifically, during the first preset time period, each sentinel base station is generally in working mode. However, during the first preset time period, there may be a situation where there is no terminal access demand for a long time. At this time, there is no need to provide communication services. Therefore, if it is always in working mode, unnecessary power consumption will be generated. Therefore, in order to further save energy, each sentinel base station can be further switched between working mode and sleep mode during the first preset time period, rather than always being in working mode. For switching in this case, a first preset duration can be specified. Each sentinel base station switches from working mode to sleep mode from the moment it enters working mode when the duration of its being in a state without target terminal access exceeds the first preset duration. When the target terminal is detected to access the sentinel base station again, it switches from sleep mode to working mode and re-sends wake-up notification information to the intermediate base stations adjacent to the sentinel base station. For each intermediate base station, the same switching mode can be adopted, but unlike the first preset duration, a second preset duration is adopted. The second preset duration is set to be no less than the duration of the high-speed rail from the starting point of the target high-speed rail line to the intermediate base station, and no less than the duration of the high-speed rail from the intermediate base station to the end point of the target high-speed rail line. For example, in real life, a high-speed rail line is used for two-way travel of the high-speed rail. Assuming the starting point is A and the end point is B, the intermediate base station will receive wake-up notification information from A to B, and will also receive wake-up notification information from B to A. At this time, it is necessary to set the second preset duration to be no less than the duration of the high-speed rail from A to the intermediate base station and the duration of the high-speed rail from B to the intermediate base station.

[0081] As an optional implementation, each intermediate base station is also used to switch from sleep mode to working mode in response to a wake-up notification message from the base station control center when it is in sleep mode, and send a wake-up notification message to the 5G base stations on both sides adjacent to itself. For example, in the case of a high-speed train delay, there will be a period of time when there is no terminal access that exceeds the second preset period. At this time, the wake-up notification message from the base station control center can be received to switch to working mode to provide communication services for the terminal.
