Fig. 3 shows a flowchart of a base station energy saving method according to 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 comprises at least one of service type characteristic value of the base station or 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 to the target service in the first preset time period and the total connection times of the base station 10-1 to the service in the first preset time period, and determines the service type characteristic value of the base station 10-1 based on the connection times of the base station to the target service and the total connection times.
All service types of the base station can be divided into common services and VIP (very important person) services; the common services comprise data services and voice services facing public network users; the VIP service includes a customized service for an industry user, such as an ultra low latency high reliability service (URLLC) service for factory production control, or a service type of priority guarantee, such as video monitoring, government and enterprise private network, or public security monitoring, and specifically, the service type may be set according to the needs of an operator. For example: the target service may be a VIP service, and the service type feature value of the base station 10-1 is a ratio of the VIP service connection times in the base station 10-1 to all service connection times in the first preset time period.
Illustratively, the base station 10-1 obtains the service type characteristic value of the base station 10-1 by the following steps:
the method comprises the following steps: the service type supported by the base station 10-1 may be preset in the base station 10-1 and indicated by a service type parameter vipervicetype (for example, vipervicetype is 1, which indicates that the service type is a VIP service type, vipervicetype is 0, which indicates that the service type is a normal service type).
Step two: 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 (e.g. SIB) to the ue. The SIB message is used to send an indication to the ue, that is, when the ue initiates a service request, a service type report message is sent to the base station 10-1, where the service type report message indicates a service type currently initiated by the ue. The service type report message carries a service type parameter vipservicitype.
Step three: the user equipment transmits a traffic type report message to the base station 10-1.
Specifically, when the user equipment initiates a VIP service request, a service type parameter vipservicietype 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 four: after receiving the service type report message, the base station 10-1 checks the service type parameter vipserviciType therein, and determines the service type initiated by the current user equipment according to the service type parameter.
Step five: the base station 10-1 counts the number of VIP service connections initiated by the user equipment and the number of all service connections within a first preset time period, and calculates the ratio of the number of VIP service connections to the number of all service connections as the service type characteristic value of the base station 10-1.
In a possible implementation manner, the base station 10-1 obtains a ratio of the number of users connected to the target user attribute of the base station 10-1 to the total number of users connected to the base station 10-1 in a first preset time period, and determines a user attribute feature value accessed to the base station 10-1 based on the ratio. The user attributes of the access base station 10-1 may be divided into common users and VIP users, and the user attributes may be set in the core network device 10-2 based on subscription information of the users. The user attribute feature value of the base station 10-1 may be a ratio of the number of VIP users to the number of all access users in a first predetermined time period.
Specifically, the base station 10-1 determines the user attribute feature value accessed to the base station 10-1 through the following steps:
the method comprises the following steps: the base station 10-1 counts an accessed user list in a first preset time period, where the user list includes information such as a user equipment identifier and a user equipment residence time.
Step two: the base station 10-1 screens out the user equipment with the residence time longer than a first preset threshold value from the access user list, and sends a user attribute query request message to the core network equipment storing the user subscription information, wherein the message comprises information such as the user list, a user attribute query request indication mark and the like.
Step three: the core network device acquires the user attribute information in the user list according to the user attribute query request message, and sends the user attribute corresponding to the user device in the acquired user list to the base station 10-1.
Step four: the base station 10-1 takes the ratio of the number of the VIP users in the user list in the first preset time period to the total number of the users in the user list as the user attribute feature value of the base station 10-1.
In one example, the user attribute may be identified by a UEpriority parameter, with a parameter value of 1 indicating a VIP user and a parameter value of 0 indicating a general user. The number of users having the user attribute of 1 in the user list is 200, the total number of users is 400, and the user attribute feature value of the base station 10-1 is 200/400 ═ 50% s.
S101: the base station 10-1 acquires the second information. Wherein the second information includes: the traffic load characteristic value of the base station 10-1 and the identification information of the co-coverage base station of the base station 10-1. The identification information of the co-coverage base station of the base station 10-1 is used for characterizing the adjacent base stations which have the co-coverage relation 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 two base stations have the same coverage area. The service load characteristic value of the base station 10-1 may be obtained based on at least one of a Physical Resource Block (PRB) utilization rate, an access user number, a data throughput rate, and the like in a first preset time period of the base station 10-1. The traffic load characteristic value is used to characterize the change in traffic load of the base station 10-1.
In one possible implementation, the base station 10-1 determines the identification information of the co-coverage base station of the base station 10-1 by:
the method comprises the following steps: the base station 10-1 transmits a request message for the user equipment to periodically measure the signal strengths of the base station 10-1 and the neighbor base stations to the user equipment connected to the base station 10-1, and reports to the base station 10-1 through a measurement report message. The measurement report message carries an identifier of the base station 10-1, an identifier of the first neighboring base station, and Reference Signal Receiving Power (RSRP) of the base station 10-1 and the first neighboring base station. The first neighboring base station is any one of the base stations neighboring the base station 10-1.
Step two: in a first preset time period, the base station 10-1 counts measurement report messages reported by the user equipment, and if the difference value between the RSRP of the base station 10-1 and the RSRP of the first adjacent base station is smaller than a second preset threshold, records the identifier of the first adjacent base station, and increases the same coverage index of the first adjacent base station 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 neighboring base station in one measurement report message acquired by the base station 10-1 is smaller than the second preset threshold, the same coverage index of the first neighboring base station is increased by 1.
Step three: if the ratio of the co-coverage index of the first neighboring base station to the total number of measurement report messages received by the base station 10-1 is greater than a third preset threshold value within a first preset time period, it is determined that the first neighboring base station and the base station 10-1 have a co-coverage relationship, and the identification information of the first neighboring base station is used as the identification information of the co-coverage base station of the base station 10-1. If there is no neighboring base station with the same coverage relation 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.
In a first preset time period, the base station 10-1 obtains a service load characteristic value of the base station 10-1 by the following method:
the method comprises the following steps: a base station 10-1 acquires a plurality of service load values in a preset unit time period; the first preset time period includes a plurality of 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 users accessing, or the data throughput rate.
Step two: and if the number of the service load values of the base station 10-1 in the preset unit time interval which are lower than the fourth preset threshold is larger than the preset first threshold, determining that the preset unit time interval is a low-load time interval.
And if the number of the service load values of the preset unit time interval higher than the preset fifth preset threshold is larger than the preset second threshold, determining that the preset unit time interval is a high-load time interval.
Step three: the base station 10-1 determines a traffic load characteristic value of the base station 10-1 based on the acquired characteristics (e.g., high load period or low load period) of the plurality of preset unit periods. The service load characteristic value is related to the number and duration of continuous low-load time periods and the size of the service load.
In one possible implementation manner, the base station determines the traffic load characteristic value of the base station 10-1 based on the acquired characteristics of the plurality of preset unit time periods in the following manner.
If the number of low-load time periods is less than or equal to a sixth preset threshold (corresponding to the first threshold), the traffic load characteristic value of the base station is set to a preset value 1.
If the number of low-load time periods is greater than a preset sixth preset threshold and the number of high-load time periods is greater than a preset 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 traffic load characteristic value is the average value of the duration of the continuous low-load period/(the duration of the unit period is the number of the continuous low-load periods).
Wherein the total duration of a plurality of temporally successive low-load time periods is defined as continuing the low-load time period; the ratio of the sum of the lengths of each time interval in the plurality of continuous low-load time intervals to the number of continuous low-load time intervals is the average value of the time intervals of the continuous low-load time intervals. The average value of all traffic load values is the average load value. In one example, the duration of the unit time period is 1 hour, and in 24 hours, the number of continuous low load time periods is 3 from 0:00 am to 3:00 am, 17:00 pm to 19:00 pm, and 12:00 pm to 14:00 pm, the sum of the lengths of each of the plurality of continuous low load time periods is 7 hours, the average of the duration of the continuous low load time periods is 7/3 hours, and the average PRB utilization rate is 60%.
Optionally, in step S102, the base station 10-1 obtains an energy saving parameter. Wherein, energy-conserving parameter includes: at least one of a traffic load value of the low load period, a start time of the low load period, or an end time of the low load period.
In one possible implementation manner, during the first preset time period, the base station 10-1 obtains the energy saving parameter by:
the method comprises the following steps: the base station 10-1 acquires a plurality of service load values in a preset unit time period; the first preset time period includes a plurality of preset unit periods. The service load value may be at least one of a PRB utilization rate, an access user number, or a data throughput rate of the base station 10-1.
Step two: the base station 10-1 obtains the load average value of the continuous low-load time period, and the starting time and the ending time of the continuous low-load time period as energy-saving parameters according to the service load value in each preset unit time period. Wherein a plurality of low load periods that are consecutive in time are collectively referred to as continuous low load periods.
S103: and the base station 10-1 determines an energy-saving scheme corresponding to the base station 10-1 according to the first information and the second information. Wherein 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 meets a first preset condition and the second information meets a second preset condition, the energy saving scheme corresponding to the obtained base station 10-1 is a symbol turn-off and channel turn-off energy saving scheme.
If the first information meets a first preset condition and the second information meets a third preset condition, acquiring that the energy-saving scheme corresponding to the base station 10-1 is a cell turn-off energy-saving scheme;
if the first information meets the first preset condition and the second information meets the fourth preset condition, the energy-saving scheme corresponding to the base station 10-1 is obtained as a 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 a seventh preset threshold (corresponding to a third threshold), and the user attribute characteristic value of the access base station 10-1 is smaller than an eighth preset threshold (corresponding to a fourth threshold).
The second preset condition may be that the traffic load characteristic value of the base station 10-1 is greater than 0 and smaller than a ninth preset threshold (corresponding to a fifth threshold).
The third preset condition is that the traffic load characteristic value of the base station 10-1 is greater than or equal to a ninth preset threshold, the traffic load characteristic value of the base station 10-1 is smaller than a tenth preset threshold (corresponding to a sixth threshold), and the second information includes identification information of the co-coverage base station of the base station 10-1.
The fourth preset condition may be that the traffic load characteristic value of the base station 10-1 is greater than or equal to a tenth preset threshold, and the second information includes identification information of co-coverage base stations of the base station 10-1.
If the service type characteristic value of the base station 10-1 is greater than the seventh preset threshold, or the user attribute characteristic value is greater than the eighth preset threshold, or the service load characteristic value is 0, it is determined that the base station 10-1 does not execute any energy saving scheme.
If the service type characteristic value of the base station 10-1 is smaller than the seventh preset threshold, the user attribute characteristic value of the access base station 10-1 is smaller than the eighth preset threshold, and the service load characteristic value of the base station 10-1 is greater than 0 and smaller than the ninth preset threshold, it is determined that the energy-saving scheme of the base station 10-1 is a symbol turn-off and channel turn-off energy-saving scheme.
If the service type characteristic value of the base station 10-1 is smaller than a seventh preset threshold, the user attribute characteristic value of the access base station 10-1 is smaller than an eighth preset threshold, the service load characteristic value of the base station 10-1 is greater than or equal to a ninth preset threshold, the service load characteristic value of the base station 10-1 is smaller than a tenth preset threshold, and the second information includes identification information of base stations with the same coverage of the base station 10-1, determining that the energy-saving scheme of the base station 10-1 is a cell turn-off energy-saving scheme.
And if the service type characteristic value of the base station 10-1 is smaller than a seventh preset threshold value, the user attribute characteristic value of the access base station 10-1 is smaller than an eighth preset threshold value, the service load characteristic value of the base station 10-1 is greater than or equal to a tenth preset threshold value, and the second information comprises identification information of base stations with the same coverage of the base station 10-1, determining that the energy-saving scheme of the base station 10-1 is a deep dormancy energy-saving scheme.
Therefore, for the base station 10-1 with a large number of VIP services or VIP users, no energy-saving turn-off operation is executed, and the service performance of the VIP services or the VIP users is preferentially ensured not to be influenced by the energy-saving turn-off. Determining a service load characteristic value through analyzing distribution characteristics of a low-load time period and a high-load time period, determining an energy-saving scheme and energy-saving parameters based on the service load characteristic value, matching the energy-saving scheme with the service load characteristics, and adopting a deep sleep mode when the service load characteristic value of a base station is large to maximize the energy-saving effect; on the contrary, other energy-saving schemes such as symbol turn-off are adopted, the turn-off time granularity is smaller, the faster hardware turn-off and turn-on conversion is realized, the base station executing energy saving can be ensured to quickly recover the normal working state when the service load is increased, the service requirement is met, and the network performance is kept 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 turn-off is not allowed to be executed, and the reduction of service performance is avoided; in addition, the energy-saving scheme also considers the same coverage relation among base stations, and only when the base stations have adjacent base stations with the same coverage, the cell is selected to be turned off or deeply dormant, so that the conditions that blind spots occur in the coverage area of the base stations after the energy-saving turn-off is triggered and the users cannot access the network are avoided; if the base station has no adjacent base station with the same coverage, only executing symbol switching-off and channel switching-off, not only saving the energy consumption of the base station through switching-off, but also ensuring that the network coverage is not influenced;
it can be understood that the base station 10-1 may determine the type of the base station 10-1 according to the first information and the second information, and the base station 10-1 prestores a corresponding relationship between the type of the base station and the energy saving scheme. The base station 10-1 may obtain a corresponding energy saving scheme according to the determined type of the base station 10-1. The triggering condition and the stopping condition for each energy saving scheme may be set according to the acquired energy saving parameters.
S104: and the base station 10-1 executes energy saving according to the acquired energy saving parameters and the determined energy saving scheme.
Specifically, the base station 10-1 sets a starting condition and a terminating condition of the determined energy saving scheme according to the acquired energy saving parameter. When the base station 10-1 meets the set starting condition, the energy-saving scheme is executed to save energy, and when the base station 10-1 meets the termination condition, the energy saving is finished and the normal working state is entered.
In one example, assuming that the energy saving scheme determined by the base station 10-1 is a cell turn-off energy saving scheme, then, when the traffic load of the base station 10-1 is lower than or equal to the average load value lasting for a low load period, the determined energy saving scheme is started to enter a turn-off state; when the traffic load of the base station 10-1 is higher than the average load value of the continuous low-load period, the base station 10-1 enters a normal working state.
In another example: if the energy-saving scheme is a deep sleep energy-saving scheme, the base station 10-1 enters a deep sleep state at the starting time of the continuous low-load time period, and wakes up the base station 10-1 at the ending time of the continuous low-load time period to enter a normal working state.
It should be noted that the step of acquiring the energy saving parameter in 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 application, the base station 10-1 determines that the base station 10-1 adopts a differentiated energy-saving scheme based on the service type characteristic value or the user attribute characteristic value of the base station 10-1 and the service load characteristic value, so that the energy-saving effect of the base station 10-1 is improved, and the service performance and the user experience can be guaranteed.
