FIG. 3 shows a schematic flowchart of a method for energy saving of a base station provided by an embodiment of the present application. The functions of the base station energy saving management device in the embodiment of the present application are integrated in the base station 10-1. As shown in FIG. 3, the method may include the following steps:

S100: The base station 10-1 acquires the first information. The first information includes at least one of a service type characteristic value of the base station or a user attribute characteristic value of the access base station.

In a possible implementation manner, the base station 10-1 obtains the connection times of the base station 10-1 connecting to the target service within the first preset time period and the total connection times of the base station 10-1 connecting to the service within the first preset time period, The service type characteristic value of the base station 10-1 is determined based on the connection times of the base station connecting the target service and the total connection times.

All business types of base stations can be divided into ordinary services and VIP (very important person, VIP) services; ordinary services include data services and voice services for public network users; VIP services include customized services for industrial users, such as for factory production Controlled ultra-low-latency and high-reliability services (ultra reliable low latency communication, URLLC) services, or video surveillance, government-enterprise private networks, or public security monitoring and other priority-guaranteed business types. Specifically, the business type can be set according to the operator's needs . For example, the above-mentioned target service may be a VIP service, and the service type characteristic value of the base station 10-1 is the ratio of the number of VIP service connections in the base station 10-1 in the number of all service connections within the first preset time period.

Exemplarily, the base station 10-1 acquires the service type characteristic value of the base station 10-1 through the following steps:

Step 1: The service type supported by the base station 10-1 can be preset in the base station 10-1 and represented by the service type parameter VIPserviceType (eg: VIPserviceType=1, indicating that the service type is VIP service type, VIPserviceType=0, indicating that the service Type is a common business type).

Step 2: The base station 10-1 carries the service type parameter field supported by the base station in the SIB message by sending a system broadcast message (eg, SIB) to the user equipment. The SIB message is used to send an instruction to the user equipment, that is, when the user equipment initiates a service request, a service type report message is sent to the base station 10-1, and the service type report message indicates the service type currently initiated by the user equipment. The service type report message carries the service type parameter VIPserviceType.

Step 3: The user equipment sends a service type report message to the base station 10-1.

Specifically, when the user equipment initiates a VIP service request, the service type parameter VIPserviceType carried in the service type report message is 1; when the user equipment initiates a common service request, the service type parameter VIPserviceType carried in the service type report message is 0 .

Step 4: After receiving the service type report message, the base station 10-1 checks the service type parameter VIPserviceType therein, and determines the service type initiated by the current user equipment according to the service type parameter.

Step 5: The base station 10-1 counts the number of VIP service connections initiated by the user equipment and the number of connections of all services within the first preset time period, and calculates the ratio of the number of VIP service connections to all the times of service connections, as the base station 10 -1 for the service type characteristic value.

In a possible implementation manner, the base station 10-1 obtains a ratio of the number of users with attributes of the target users connected to the base station 10-1 within the first preset time period to the total number of users connected to the base station 10-1, and determines based on the ratio. Access the user attribute characteristic value of the base station 10-1. The user attributes of the access base station 10-1 can be divided into ordinary users and VIP users, and the user attributes can be set in the core network device 10-2 based on the user's subscription information. The user attribute characteristic value of the base station 10-1 may be the ratio of the number of VIP users to the number of all access users in the first preset time period.

Specifically, the base station 10-1 determines the attribute characteristic value of the user accessing the base station 10-1 through the following steps:

Step 1: The base station 10-1 counts a list of accessed users within the first preset time period, where the user list includes information such as user equipment identifiers, user equipment residency duration, and the like.

Step 2: The base station 10-1 filters out the user equipment whose dwell time is greater than the first preset threshold from the access user list, and sends a user attribute query request message to the core network device that stores the user subscription information, where the message includes the user equipment. List, user attribute query request indicator and other information.

Step 3: The core network device obtains the user attribute information in the user list according to the user attribute query request message, and sends the obtained user attribute corresponding to the user equipment in the user list to the base station 10-1.

Step 4: The base station 10-1 takes the ratio of the number of VIP users in the user list to the total number of users in the user list in the first preset time period as the user attribute characteristic value of the base station 10-1.

In one example, the user attribute can be identified by the UEpriority parameter, if the parameter value is 1, it indicates a VIP user, and if the parameter value is 0, it indicates a normal user. The number of users whose user attribute is 1 in the user list is 200, and the total number of users is 400. The user attribute characteristic value of the base station 10-1 is 200/400=50%s.

S101: The base station 10-1 acquires the second information. The second information includes: the service load characteristic value of the base station 10-1 and the identification information of the same-coverage base station of the base station 10-1. The identification information of the base station with the same coverage of the base station 10-1 is used to represent the neighboring base stations that have the same coverage relationship with the base station 10-1. The co-coverage base station of the base station 10-1 has a co-coverage relationship with the base station 10-1, which means that the two base stations have the same coverage area. The service load characteristic value of the base station 10-1 may be based on at least one of the physical resource block (PRB) utilization rate, the number of access users, or the data throughput rate of the base station 10-1 within the first preset time period. one gets. The traffic load characteristic value is used to characterize the variation characteristics of the traffic load of the base station 10-1.

In a possible implementation manner, the base station 10-1 determines the identification information of the same-coverage base station of the base station 10-1 in the following manner:

Step 1: The base station 10-1 sends a request message to the user equipment connected to the base station 10-1. The request message is used by the user equipment to periodically measure the signal strengths of the base station 10-1 and the neighboring base stations, and report it through a measurement report message to base station 10-1. The measurement report message carries the identity of the base station 10-1, the identity of the first adjacent base station, and the reference signal receiving power (RSRP) of the base station 10-1 and the first adjacent base station. The first adjacent base station is any base station adjacent to the base station 10-1.

Step 2: During the first preset time period, the base station 10-1 counts the measurement report messages reported by the user equipment, if the difference between the RSRP of the base station 10-1 and the RSRP of the first adjacent base station is less than the second preset If the threshold is set, the identifier of the first adjacent base station is recorded, and the co-coverage index of the first adjacent base station is increased by 1. The initial value of the co-coverage index of the first neighboring base station may be set to 0.

If the difference between the RSRP of the base station 10-1 and the RSRP of the first adjacent base station in a measurement report message obtained by the base station 10-1 is smaller than the second preset threshold, the same coverage index of the first adjacent base station Increase by 1.

Step 3: If the ratio of the same coverage index of the first adjacent base station to the total number of measurement report messages received by the base station 10-1 within the first preset time period is greater than the third preset threshold, determine the first phase. The neighboring base station and the base station 10-1 have a same coverage relationship, and the identification information of the first neighboring base station is used as the identification information of the same coverage base station of the base station 10-1. If there is no adjacent base station that has the same coverage relationship with the base station 10-1, the second information does not include the identification information of the same coverage base station of the base station 10-1.

During the first preset time period, the base station 10-1 acquires the service load characteristic value of the base station 10-1 in the following manner:

Step 1: The base station 10-1 acquires multiple service load values within a preset unit period; the first preset period includes multiple preset unit periods. The service load value may be at least one of the PRB utilization rate of the physical resource block of the base station 10-1, the number of access users, or the data throughput rate.

Step 2: If the number of traffic load values of the base station 10-1 in the preset unit period that is lower than the fourth preset threshold is greater than the preset first threshold, the preset unit period is determined to be a low load period.

If the number of the traffic load value of the preset unit period higher than the preset fifth preset threshold value is greater than the preset second threshold, it is determined that the preset unit period is a high load period.

Step 3: The base station 10-1 determines the service load characteristic value of the base station 10-1 based on the acquired characteristics of a plurality of preset unit periods (eg, a high load period or a low load period). Among them, the characteristic value of the business load is related to the number and duration of the continuous low load period, and the size of the business load.

In a possible implementation manner, the base station determines the service load characteristic value of the base station 10-1 based on the acquired characteristics of multiple preset unit time periods in the following manner.

If the number of low-load periods is less than or equal to the sixth preset threshold (corresponding to the first threshold), the service load characteristic value of the base station is set to a preset value of 1.

If the number of low-load periods is greater than the preset sixth preset threshold, and the number of high-load periods is greater than the seventh preset threshold (corresponding to the second threshold), the service load characteristic value of the base station can be calculated by the following formula :

The characteristic value of the traffic load=the average value of the duration of the continuous low load period/(the duration of the unit period*the number of the continuous low load period*the average load value).

Among them, the total duration of multiple temporally continuous low-load periods is defined as the continuous low-load period; the ratio of the sum of the lengths of each of the multiple continuous low-load periods to the number of continuous low-load periods is the continuous low-load period The mean duration of the load period. The average of all business load values is the average load value. In one example, the duration of the unit period is 1 hour, and in 24 hours, the continuous low load period is 0:00 am to 3:00 am, 17:00 pm to 19:00 pm, and 12:00-14 pm :00. The number of continuous low load periods is 3, the sum of the length of each period in multiple continuous low load periods is 7 hours, the average duration of continuous low load periods is 7/3 hours, and the average PRB utilization rate is 60%.

Optionally, S102: the base station 10-1 obtains energy saving parameters. Wherein, the energy saving parameter includes at least one of a service load value of a low load period, a start time of the low load period, or an end time of the low load period.

In a possible implementation manner, within the first preset time period, the base station 10-1 acquires the energy saving parameters in the following manner:

Step 1: The base station 10-1 obtains a plurality of service load values within a preset unit time period; the first preset time period includes a plurality of preset unit time periods. The service load value may be at least one of the PRB utilization rate of the physical resource block of the base station 10-1, the number of access users, or the data throughput rate.

Step 2: The base station 10-1 obtains, according to the service load value in each preset unit period, the load average value of the continuous low load period, the start time and the end time of the continuous low load period, as energy saving parameters. Among them, a plurality of time-continuous low-load periods are collectively referred to as continuous low-load periods.

S103: The base station 10-1 determines the energy saving scheme corresponding to the base station 10-1 according to the first information and the second information. The energy saving scheme is used for the base station 10-1 to perform energy saving processing according to the energy saving scheme.

In a possible implementation manner, if the first information satisfies the first preset condition and the second information satisfies the second preset condition, the acquired energy saving scheme corresponding to the base station 10-1 is symbol off and channel off to save energy Program.

If the first information satisfies the first preset condition and the second information satisfies the third preset condition, the acquired energy saving scheme corresponding to the base station 10-1 is the cell shutdown energy saving scheme;

If the first information satisfies the first preset condition and the second information satisfies the fourth preset condition, the acquired energy saving scheme corresponding to the base station 10-1 is the deep sleep energy saving scheme.

The first preset condition may be that the service type characteristic value of the base station 10-1 is smaller than the seventh preset threshold (corresponding to the third threshold), and the user attribute characteristic value of the access base station 10-1 is smaller than the eighth preset threshold ( corresponding to the fourth threshold).

The second preset condition may be that the service load characteristic value of the base station 10-1 is greater than 0 and less than the ninth preset threshold (corresponding to the fifth threshold).

The fourth preset condition may be that the service load characteristic value of the base station 10-1 is greater than or equal to the tenth preset threshold, and the second information includes identification information of the same-coverage base station of the base station 10-1.

If the service type characteristic value of the base station 10-1 is less than the seventh preset threshold, and the user attribute characteristic value of the access base station 10-1 is less than the eighth preset threshold, and the service load characteristic value of the base station 10-1 is greater than 0, and If it is less than the ninth preset threshold, it is determined that the energy saving scheme of the base station 10-1 is the symbol off and channel off energy saving scheme.

In this way, for the base station 10-1 with a large number of VIP services or VIP users, no energy-saving shutdown operation is performed, and the service performance of the VIP services or VIP users is preferentially guaranteed not to be affected by the energy-saving shutdown. Through the analysis of the distribution characteristics of the low load period and the high load period, the characteristic value of the service load is determined, and the energy saving scheme and energy saving parameters are determined based on the characteristic value of the service load, so that the energy saving scheme matches the characteristics of the service load. When it is large, the deep sleep mode is adopted to maximize the energy saving effect; on the contrary, other energy saving schemes such as symbol shutdown are adopted, the time granularity of shutdown is smaller, and faster hardware shutdown and startup transitions are realized, ensuring that when the business load increases The base station that performs energy saving quickly returns to the normal working state to meet the service requirements and keep the network performance consistent; if the service load characteristic value is 0, the random fluctuation of the service load is strong or the load is high, the energy saving shutdown is not allowed to avoid Causes service performance degradation; in addition, the selection of the energy-saving scheme also considers the same coverage relationship between base stations. Only when the base station has adjacent base stations with the same coverage, the cell shutdown or deep sleep is selected, which avoids the need for energy-saving shutdown after triggering. Blind spots occur in the coverage area of the base station, and users cannot access the network; if the base station has no adjacent base stations with the same coverage, only symbol shutdown and channel shutdown are performed, which not only saves the energy consumption of the base station, but also ensures network coverage. not affected;

It can be understood that the base station 10-1 can determine the type of the base station 10-1 according to the first information and the second information, and the base station 10-1 pre-stores the corresponding relationship between the base station type and the energy saving solution. The base station 10-1 may acquire a corresponding energy saving solution according to the determined type of the base station 10-1. The trigger condition and stop condition for each energy saving scheme can be set according to the obtained energy saving parameters.

S104: The base station 10-1 performs energy saving according to the acquired energy saving parameters and the determined energy saving scheme.

Specifically, in the base station 10-1, the start condition and the termination condition of the determined energy saving scheme are set according to the acquired energy saving parameters. When the base station 10-1 satisfies the set start condition, the energy saving scheme is executed to save energy, and when the base station 10-1 satisfies the termination condition, it ends the energy saving and enters the normal working state.

In an example, it is assumed that the energy saving scheme determined by the base station 10-1 is the cell shutdown energy saving scheme, then, when the traffic load of the base station 10-1 is lower than or equal to the load average value of the continuous low load period, the determined energy saving scheme is activated to enter the Off state; when the traffic load of the base station 10-1 is higher than the load average value of the continuous low load period, the base station 10-1 enters the normal working state.

In another example: if the energy saving scheme is the deep sleep energy saving scheme, the base station 10-1 enters the deep sleep state at the beginning of the continuous low load period, wakes up the base station 10-1 at the end of the continuous low load period, and enters the normal state working status.

It should be noted that the step of obtaining the energy saving parameter in the above S102 is an optional step, and the energy saving parameter may also be preset in the base station 10-1 according to experience.

In the embodiment of the present application, the base station 10-1 determines that the base station 10-1 adopts a differentiated energy-saving solution based on the "service type characteristic value or user attribute characteristic value" and the service load characteristic value of the base station 10-1, which not only improves the efficiency of the base station 10-1 1 energy-saving effect, but also to ensure business performance and user experience.
