Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to a base station energy saving method and device, equipment and computer readable storage medium. BACKGROUND

[0002] With the development of mobile communication network, the energy consumption of wireless network is increasing, and the demand of operators for energy saving is becoming more and more urgent. In the energy consumption of wireless network, the energy consumption of base station equipment accounts for the highest proportion, so the base station energy saving is the basis of wireless network energy saving, and the base station energy saving has always been a research hotspot in the industry.

[0003] In order to reduce the energy consumption of base station equipment, the industry has proposed symbol off, channel off, cell off and other energy saving technologies. The basic principle is to judge based on the base station traffic load, if the traffic load is lower than the preset energy saving trigger threshold, the trigger condition of energy saving technology is met, then the part of hardware resources of the base station can be closed in network idle time, so that the base station enters the corresponding energy saving state, thereby achieving the effect of base station energy saving.

[0004] However, since shutting down the hardware resources of the base station will cause different degrees of influence on the network performance of the energy saving area or the terminal service experience. Therefore, the existing energy saving technology can only be used in the period of small traffic load, and cannot be applied to the period of high traffic load, so the energy saving effect is limited; at the same time, when the traffic load of the base station increases, the base station needs to restart the hardware resources that have been shut down, which will cause different degrees of wake-up delay and cannot respond to the service demand of the base station in time. SUMMARY

[0005] The present application provides a base station energy saving method and device, equipment and computer readable storage medium, which is used to solve the problem that the existing base station energy saving method can only shut down the hardware resources of the base station in the period of low load, resulting in limited energy saving effect and wake-up delay, so that the base station in energy saving state cannot respond to the service demand of the base station in time.

[0006] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0007] In a first aspect, the present application provides a base station energy saving method, which is applied to a first base station, and the first base station is any one base station deployed in a preset area.

[0008] The base station energy saving method provided by the present application comprises:

[0009] The first base station acquires a measurement report sent by at least one terminal in a preset area. The measurement report comprises one or more of the following: signal strength of a serving cell, signal strength of at least one neighboring cell of the serving cell. The serving cell is a cell served by the first base station. The neighboring cell is a cell served by a second base station in the preset area. The first base station determines a control base station of the first base station according to the at least one measurement report. The first base station enters a target energy-saving state and sends a first message to the control base station. The first message is used to send a public signaling message to be transmitted to the control base station. The target energy-saving state is used to indicate that the first base station stops transmitting the public signaling message.

[0010] In the present application, the first base station determines a control base station of the first base station by acquiring a measurement report sent by at least one terminal in a preset area, and then enters a target energy-saving state and sends a first message to the control base station to send a public signaling message to be transmitted by the first base station to the control base station, so that the control base station establishes a signaling connection with a terminal corresponding to the public signaling message. In the present application, the first base station stops transmitting the public signaling message to enter the target energy-saving state by determining the control base station corresponding to the first base station, so as to reduce the energy consumption of the base station. The public signaling message to be transmitted is sent to the control base station, so that the terminal under the first base station establishes a signaling connection with the control base station, and a service connection is established with a base station corresponding to the service through the control base station, so as to meet the service demand of the terminal. This process does not need to shut down the hardware resources of the base station, and can be used for energy saving in different service load scenarios, so as to effectively reduce the energy consumption of the base station.

[0011] In a possible implementation manner, the first base station determines a control base station of the first base station according to the at least one measurement report, comprising: if a difference between the signal strength of the serving cell and the signal strength of one neighboring cell in the measurement report is less than a preset signal strength threshold, the first base station determines that the measurement report is a target measurement report; if a ratio of a number of the target measurement reports to a number of the measurement reports is greater than a preset ratio, the first base station determines that a second base station is a same coverage base station of the first base station; if the second base station is a non-energy-saving base station, the first base station determines that the second base station is a compensation base station of the first base station; the first base station sends a base station state request message to at least one compensation base station. The state request message is used to indicate to acquire state information of the compensation base station. The first base station determines the control base station of the first base station according to the state information and a same coverage ratio of the compensation base station to the first base station. The control base station is one of the at least one compensation base station. The same coverage ratio is a ratio of the number of the target measurement reports to the number of the measurement reports.

[0012] In the possible implementation, the first base station determines the corresponding compensation base station of the first base station according to the measurement report, so that the terminal accessing the first base station can simultaneously access the corresponding compensation base station, and when the first base station enters the target energy-saving state and stops sending the public signaling message, the terminal can receive the public signaling message by accessing the compensation base station, and the service connection requirement is met.

[0013] In a possible implementation, the state information includes one or more of the following: energy efficiency, signaling capacity. The first base station determines the control base station of the first base station according to the state information and the same coverage proportion of the compensation base station and the first base station, including: the first base station determines the weighted sum of the compensation base station according to one or more of the same coverage proportion, the energy efficiency, and the signaling capacity. The first base station determines the compensation base station with the maximum weighted sum as the control base station of the first base station.

[0014] In the possible implementation, the control base station determines the corresponding control base station of the first base station according to the same coverage proportion, the energy efficiency, and the signaling capacity of the compensation base station. By determining the base station with a larger same coverage proportion as the control base station, the terminal under the first base station can receive a signal with a larger strength after accessing the control base station. By determining the base station with a larger energy efficiency as the control base station, the base station can consume less energy on the premise of transmitting the same amount of traffic, and reduce the energy consumption of the control base station. By determining the base station with a larger signaling capacity as the control base station, the transmission requirement of more public signaling messages can be met, and the service performance of the terminal is guaranteed.

[0015] In a possible implementation, the energy-saving method of the base station provided in the application further includes: the first base station sends a second message to the first terminal. The first terminal is any one of the at least one terminal. The second message is used to instruct the first terminal to establish a signaling connection with the control base station.

[0016] In the possible implementation, after the first base station enters the target energy-saving state, the first base station stops sending the public signaling message over the air interface, and sends the second message to the control base station to instruct the first terminal to establish a signaling connection with the control base station. In this process, after the first base station enters the target energy-saving state, the public signaling message to be transmitted can be forwarded to the first terminal by the control base station, so that the signaling transmission requirement of the first terminal is met while the first base station is energy-saving.

[0017] In a second aspect, the application discloses an energy-saving method of a base station, applied to a control base station. The energy-saving method of the base station provided in the application includes: the control base station receives a first message sent by a first base station. The first message includes: a public signaling message to be transmitted. The control base station establishes a signaling connection with a first terminal according to the public signaling message. The first terminal is any terminal of a service cell of the first base station.

[0018] The energy saving method of the base station provided in the application can reduce the energy consumption of the first base station while meeting the service requirements of the terminals in the service cell of the first base station.

[0019] In a possible implementation, the energy saving method of the base station provided in the application further includes: controlling the base station to receive a service request message of the first terminal sent by the first terminal. The service request message includes one or more of the following: terminal location information and service type information. The base station is controlled to determine a third base station according to the location information and the service type information. The base station is controlled to send a third message to the first terminal. The third message is used to instruct the first terminal to establish a service connection with the third base station.

[0020] In this possible implementation, after the first terminal enters a target energy saving state, the first terminal under the first base station accesses the control base station, sends a service request message to the control base station, makes the control base station determine the third base station corresponding to the terminal, determines the third base station as the base station that supports the service type of the first terminal and is closest to the first terminal, and instructs the first terminal to access the corresponding third base station to establish a service connection, so that the first base station can be saved in energy while meeting the service transmission requirements of the first terminal under the service cell of the first base station.

[0021] In a possible implementation, the control base station determines the third base station according to the location information and the service type information, including: the control base station acquires state information of the same coverage base station. The state information includes location information and service capability information of the same coverage base station. The control base station determines a same coverage base station whose service capability matches the service type of the first terminal as a first same coverage base station according to the service capability information of the same coverage base station and the service type information of the first terminal. The control base station determines the distance between the first same coverage base station and the first terminal according to the terminal location information and the location information of the same coverage base station. The control base station determines the third base station according to the first same coverage base station and the distance. In a possible implementation, the control base station determines the third base station according to the first same coverage base station and the distance, including: the control base station determines the first same coverage base station with the minimum distance as the third base station.

[0022] In this possible implementation, the control base station determines the third base station as the same coverage base station that supports the service type of the first terminal and is closest to the first terminal, and instructs the first terminal to establish a service connection with the third base station, so that the service execution effect of the first terminal can be guaranteed.

[0059] In order to facilitate understanding, the related technical terms involved in the present application will be explained.

[0060] The target energy-saving state is that the base station stops transmitting public signaling messages after entering the target energy-saving state, so as to reduce the energy consumption of the base station.

[0061] At present, in order to reduce the energy consumption of base station equipment, the industry proposes symbol off, channel off, cell off and other energy-saving technologies. The basic principle of the off technology is that the base station closes part of the hardware resources of the base station in the network idle time, so as to save the energy consumption of the base station.

[0062] The existing energy-saving technology has different degrees of influence on the network performance or terminal service experience in the energy-saving area. For example, in the symbol off and channel off state, the terminal can normally access the network and transmit services, but the coverage and capacity performance of the cell will decrease after the channel is off; in the cell off state, the terminal will not be able to normally access the network and needs to re-access other non-off cells. Therefore, the existing energy-saving technology can only be used in part of the period with small service load, and cannot be applied to the period with high service load, so the energy-saving effect is limited; at the same time, when the service load increases, the hardware resources that have been turned off need to be restarted, which will bring different degrees of wake-up delay and cannot meet the service demand in time.

[0063] Based on this, the application provides an energy-saving method of a base station, and the basic principle is that: a first base station acquires a measurement report sent by at least one terminal in a preset area, and the measurement report carries the signal strength of a service cell of the first base station and the signal strength of a neighboring cell of the service cell. Then, according to the at least one measurement report, a control base station of the first base station is determined. After the control base station of the first base station is determined, the first base station enters a target energy-saving state, and sends a first message to the control base station to send a public signaling message to be transmitted to the control base station. After receiving the first message sent by the first base station, the control base station establishes a signaling connection with the first terminal according to the public signaling message in the first message.

[0064] In the application, the first base station determines the control base station of the first base station according to the measurement report sent by at least one terminal in the preset area, and then enters a target energy-saving state, and sends a first message to the control base station to make the first terminal under the first base station establish a signaling connection with the control base station. After the first base station enters the target energy-saving state, the resource consumption of the base station caused by the transmission of the public signaling message can be reduced by stopping the transmission of the public signaling message, and then the energy consumption of the base station is reduced. The method does not need to turn off the hardware resources of the base station, has no influence on the service performance, can be used for energy saving in the period with high service load and the period with low service load at the same time, and can improve the energy-saving effect of the base station.

[0065] The implementation manners of the embodiments of the application will be described in detail below with reference to the drawings.

[0066] The scheme provided by the application can be applied to Figure 1 In the energy-saving system 100 of the base station, the system includes: a first base station 101, at least one second base station 102, a control base station 103, at least one first terminal 104 and a third base station 105.

[0067] The first base station 101 is a base station in any one of the preset areas. The first base station 101 is configured to acquire a measurement report transmitted by at least one first terminal 104 in the preset area, and determine a control base station 103 of the first base station by using the measurement report, the control base station 103 being a base station in the at least one second base station 102 that satisfies a control condition. The first base station 101 enters a target energy-saving state, and transmits a first message to the control base station 103 of the first base station 101, so as to transmit a public signaling message to be transmitted by the first base station 101 to the control base station 103.

[0068] The control condition can be that if a difference between a signal strength of a serving cell of the first base station 101 and a signal strength of a serving cell of the second base station 102 in the measurement report is less than a preset signal strength threshold, the measurement report is determined as a target measurement report. If a ratio of a number of the target measurement reports to a number of the measurement reports is greater than a preset ratio, the second base station 102 is determined as a same-coverage base station of the first base station 101. If the second base station 102 is a non-energy-saving base station, the second base station 102 is determined as a compensation base station of the first base station 101. A base station with the largest weight in the compensation base station is the control base station, and the weight is a weighted sum of at least one of a same-coverage proportion, an energy efficiency, and a signaling capacity in state information of the compensation base station.

[0069] The second base station 102 is any one base station in the preset area that is time-frequency synchronized with the first base station 101. The second base station 102 can be one or more, and the number of the second base station 102 is not limited in the present application.

[0070] The control base station 103 is a base station in the at least one second base station 102 that satisfies the control condition. The control base station 103 is configured to receive the first message transmitted by the first base station 101, and establish a signaling connection between a public signaling message in the first message and any terminal in a serving cell of the first base station. Further, the control base station 103 is also configured to, when receiving a service request message transmitted by a terminal that has established the signaling connection, determine a third base station 105 corresponding to the service request message, and transmit a third message to the terminal, so as to enable the terminal to establish a service connection with the third base station 105.

[0071] The first terminal 104 is any one terminal in a serving cell of the first base station 101. The terminal can be a mobile phone, a tablet computer, a smart watch, or the like, and the number and type of the first terminal are not limited in the present application.

[0072] The third base station 105 is configured to establish a service connection with the terminal, and perform service data transmission.

[0073] It should be noted that the above Figure 1 The energy-saving system of the base station is only an example of an application scenario of the scheme of the present application, and is not a limitation on the application scenario of the scheme of the present application.

[0074] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0075] In one aspect, the present application discloses a power saving method of a base station, which can be applied to the above-mentioned Figure 1 The power saving method of the base station is described in detail below through the interaction process between the first base station and the control base station,

[0076] As shown in the figure, the power saving method of the base station disclosed by the present application can include the following steps: Figure 2

[0077] S201, the first base station acquires the measurement report sent by at least one terminal in a preset area.

[0078] The measurement report includes one or more of the following: signal strength of a serving cell, signal strength of at least one neighboring cell of the serving cell. The serving cell is a cell served by the first base station. The neighboring cell is a cell served by the second base station in the preset area.

[0079] Specifically, the process of the first base station acquiring the measurement report sent by at least one terminal in the preset area can be that the first base station sends a measurement report acquisition request to the terminal, and the terminal sends the measurement report to the first base station in response to the acquisition request. Or the process can also be that the terminal sends the measurement report to the first base station at regular intervals, and the present application does not limit the process.

[0080] For example, the first base station receives the measurement report sent by the terminal, which carries the signal strength of the serving cell of the first base station measured by the terminal, and the signal strength of at least one neighboring cell of the serving cell.

[0081] It should be noted that the second base station is time-frequency synchronized with the first base station.

[0082] S202, the first base station determines the control base station of the first base station according to the at least one measurement report.

[0083] Specifically, after receiving the measurement report sent by the terminal, if the difference between the signal strength of the serving cell and the signal strength of any one of the neighboring cells of the serving cell in the measurement report is less than a preset signal strength threshold, the first base station determines the measurement report as a target measurement report. The serving cell is a cell currently served by the first base station. The neighboring cell is a cell served by the second base station.

[0084] ​Further, if the ratio of the number of target measurement reports to the number of measurement reports received by the first base station is greater than a preset ratio, the second base station is determined to be a same-coverage base station of the first base station. Meanwhile, the ratio of the number of target measurement reports to the total number of measurement reports received by the first base station is determined to be the same-coverage ratio of the second base station.

[0085] Still further, if at least one non-energy-saving base station is included in the same-coverage base stations of the first base station in a preset period, the at least one non-energy-saving base station is determined to be a compensation base station corresponding to the first base station.

[0086] The non-energy-saving base station does not have a corresponding same-coverage base station.

[0087] It should be noted that the base station A and the base station B are any two base stations that are time-frequency synchronized in a preset area. If the same-coverage base stations of the base station A and the base station B are only one, and are the same-coverage base stations of each other, that is, the base station A is the same-coverage base station of the base station B, and the base station B is the same-coverage base station of the base station A, then the same-coverage base stations of the base station A and the base station B do not include non-energy-saving base stations. At this time, the base station with greater energy efficiency or signaling capacity can be determined as the compensation base station of the other base station according to the energy efficiency or signaling capacity of the base station A and the base station B. For example, if the energy efficiency of the base station B is greater than that of the base station A, the base station B is determined as the compensation base station of the base station A.

[0088] After determining the compensation base stations of the first base station, the first base station sends a base station state request message to each compensation base station, and the base station state request message is used to acquire at least one of the energy efficiency or the signaling capacity of the compensation base station. The energy efficiency is the ratio of the average of the base station traffic to the average of the energy consumption of the base station in a preset period. The signaling capacity is the number of wireless resources that can be used for the transmission of public signaling information of the base station, and the number of wireless resources includes physical resource blocks (PRBs), power, and the like.

[0089] After receiving the base station state request message sent by the first base station, the compensation base station sends a base station state indication message to the first base station, and the base station state indication message carries the state information of the compensation base station, including the identification of the compensation base station, and at least one of the energy efficiency or the signaling capacity in a preset period, which is periodically counted by each base station.

[0090] After receiving the base station state indication message sent by the compensation base station, the first base station determines the control base station of the first base station according to the state information of the compensation base station in the state indication message and the same-coverage ratio of the compensation base station and the first base station. The same-coverage ratio of the compensation base station and the first base station is the ratio of the number of target measurement reports to the number of measurement reports. The control base station is the base station with the maximum weight in the at least one compensation base station, and the weight is the weighted sum of at least one of the same-coverage ratio, the energy efficiency, and the signaling capacity.

[0091] In the embodiment, if there are multiple compensation base stations for the first base station, the control base station corresponding to the first base station is further determined from the multiple compensation base stations according to the same coverage ratio, energy efficiency, and signaling capacity of each compensation base station. By determining the compensation base station with a larger same coverage ratio as the control base station, the signal strength received by the first terminal after accessing the control base station can be larger, and the service performance can be better. By determining the compensation base station with a larger energy efficiency as the control base station, the energy consumption can be smaller on the premise of transmitting the same service amount, and the energy consumption of the control base station can be reduced. By determining the compensation base station with a larger signaling capacity as the control base station, the transmission demand of more public signaling information can be met, and the service performance of the terminal can be ensured.

[0092] S203, the first base station enters a target energy-saving state and sends a first message to the control base station.

[0093] The first message is used to send the public signaling message to be transmitted to the control base station. The target energy-saving state is used to indicate that the first base station stops transmitting the public signaling message.

[0094] Specifically, after determining the control base station of the first base station, the first base station enters a target energy-saving state and sends a first message to the control base station of the first base station.

[0095] For example, the public signaling message in the first message can be an air interface message, which is used to transmit a cell synchronization message, system broadcast information, and the like. The public signaling message is transmitted according to a certain period, and occupies preset time-frequency resources and power resources. The shorter the transmission period of the public signaling message, and the more time-frequency and power resources occupied, the greater the energy consumption of the base station.

[0096] It should be noted that the base station in the target energy-saving state can normally establish a service connection, and does not affect the service data transmission of the terminal.

[0097] In the embodiment, after the first base station enters the target energy-saving state, the first base station stops sending the public signaling message on the air interface, and forwards the public signaling information to be transmitted to the control base station by sending the first message to the control base station. The public signaling information to be transmitted is sent to the first terminal through the air interface message of the control base station, so that the signaling transmission demand of the terminal is met while the first base station is energy-saving.

[0098] S204, the control base station receives the first message sent by the first base station.

[0099] The first message includes: public signaling message to be transmitted.

[0100] S205, the control base station establishes a signaling connection with the first terminal according to the public signaling message.

[0101] The first terminal is any terminal of a service cell of the first base station.

[0102] Specifically, the control base station transmits the common signaling message to be transmitted by the first base station through an air interface message after receiving the first message sent by the first base station. The signaling connection between the first terminal and the control base station is established according to the common signaling message.

[0103] It should be noted that the common signaling message to be transmitted in the first message can be encapsulated in the common signaling message of the control base station and transmitted to the target terminal, or can be transmitted through a separate air interface message. The air interface message can be a system message, a radio resource control (RRC) message, and the like. The signaling connection between the first terminal and the control base station is established by receiving the air interface message of the control base station to receive the common signaling message of the first base station.

[0104] The first base station of the present application determines the control base station corresponding to the first base station, so that the first base station stops transmitting the common signaling message to enter the target energy-saving state, reduces the energy consumption of the base station, and indicates the first terminal to establish a signaling connection with the control base station and a service connection with the third base station to meet the service demand of the terminal. The present application does not need to shut down the hardware resources of the first base station and has no influence on the service performance of the first base station, and can be used for energy saving in different service load scenarios, effectively reducing the energy consumption of the base station and meeting the service demand of the terminal.

[0105] Further, after S205, as shown in Figure 3 The energy-saving method of the base station provided by the embodiments of the present application can further include S206-S209.

[0106] S206, the first base station sends a second message to the first terminal.

[0107] The first terminal is any one of at least one terminal. The second message is used to instruct the first terminal to establish a signaling connection with the control base station.

[0108] For example, the second message can carry the identifier of the control base station, the signaling connection establishment instruction, and the like.

[0109] The first base station sends a second message to the first terminal. After receiving the second message sent by the first base station, the first terminal switches the signaling connection established with the first base station to the control base station and establishes a signaling connection with the control base station.

[0110] It should be noted that the signaling connection switching process can be that the first terminal in the no-service data transmission state can directly disconnect the signaling connection between the first base station and establish the signaling connection with the control base station, and receive the public signaling message of the first base station through the control base station. The first terminal in the service data transmission state can maintain the connection with the first base station, and after the service data transmission is completed or a preset time length is reached, the first terminal switches the signaling connection to the control base station, and receives the public signaling message of the first base station through the control base station.

[0111] S207, the control base station receives the service request message of the first terminal sent by the first terminal.

[0112] The service request message includes one or more of the following: terminal location information, service type information.

[0113] S208, the control base station determines the third base station according to the location information and the service type information.

[0114] Specifically, the control base station obtains the current location information of the first terminal. For example, the control base station can determine the current location information of the first terminal based on base station positioning technology. Alternatively, the first terminal can determine the current location information of the first terminal based on terminal-side positioning technology, and report the location information to the control base station by sending a message.

[0115] The control base station obtains the service type information of the first terminal. Specifically, the first base station can obtain the service type information of the first terminal from the service request message sent by the first terminal to the control base station. The service request message carries terminal identification, terminal requested service type and other information. The service type includes but is not limited to voice service, data service, etc.

[0116] The control base station obtains the service capability information of each corresponding same coverage base station. For example, the control base station can obtain the service capability information of each same coverage base station through message interaction between the control base station and each same coverage base station. Specifically, the control base station sends a service capability request message to each same coverage base station to obtain the service capability information of each same coverage base station. Each same coverage base station sends a service capability indication message to the control base station, which carries the same coverage base station identification and service capability information. The service capability information of the base station is used to indicate whether the base station supports voice service. For example, if the base station supports voice service, the service capability information is 1. If the base station does not support voice service, the service capability information is 0.

[0117] The control base station determines the distance between each same coverage base station and the first terminal according to the location information of each corresponding same coverage base station and the current location information of the first terminal. The location information includes latitude and longitude information. The location information of the same coverage base station can be pre-stored in the control base station.

[0118] The same-coverage base station with which the service capability matches the service type of the first terminal is determined as the third base station corresponding to the first terminal. If the service type of the third base station includes voice service and the same-coverage base station supports voice service, it is considered that the service capability of the same-coverage base station matches the service type of the first terminal.

[0119] In the embodiment, after the first base station enters the target energy-saving state, the first terminal under the first base station accesses the control base station, and sends a service request message to the control base station, so that the control base station determines the third base station corresponding to the first terminal. The same-coverage base station closest to the first terminal and supporting the service type of the first terminal is determined as the third base station, and the first terminal is instructed to access the corresponding third base station to establish a service connection, so that the service transmission demand of the terminal can be met while the first base station is in energy-saving state.

[0120] S209, the control base station sends a third message to the first terminal.

[0121] The third message is used to instruct the first terminal to establish a service connection with the third base station. The first terminal identifier, the third base station identifier, and the service connection establishment instruction message can be carried in the third message.

[0122] For example, the control base station sends a third message to the first terminal. After receiving the third message sent by the control base station, the first terminal sends a service request message to the third base station again, establishes a service connection with the third base station, and performs service data transmission. After the service data transmission is completed, the first terminal can disconnect the service connection with the third base station and keep the signaling connection with the control base station.

[0123] In the embodiment, the first terminal establishes a signaling connection with the control base station, and is used for receiving common signaling information, so that the first base station can enter a target energy saving state to reduce energy consumption of the first base station. Meanwhile, the first terminal establishes a service connection with the third base station, and is used for service data transmission to meet the service transmission requirement of the terminal. In this way, the decoupling of the signaling connection and the service connection, that is, the signaling connection and the service connection of the terminal can be located in different base stations, so that the beneficial effects of reducing energy consumption of the base station and guaranteeing service performance of the terminal can be achieved.
