Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

The appearance of the 5G network greatly improves the network performance of the mobile network, can provide higher-speed and finer communication services for the terminal, but has higher energy consumption compared with the 4G network, which greatly increases the operation cost of the mobile operator. The high energy consumption of the 5G network is mainly represented by the 5G base station, and compared with the 4G base station, the hardware capability and the software capability of the 5G base station are improved, but the energy consumption is increased, so that the energy consumption of the 5G network is greatly increased.
Currently, mobile operators mainly reduce operation cost through a base station energy-saving mode. The base station energy saving technology comprises equipment-level energy saving, station-level energy saving and network-level energy saving, wherein the equipment-level energy saving mainly realizes energy saving through hardware design; the station-level energy saving mainly performs software energy saving from the aspects of frame and channel turn-off, namely deep dormancy and the like, and the main idea is that the refined energy saving of the base station is realized by means of timely closing part of equipment, cells, channels or power amplifiers and the like on the premise of ensuring network quality and terminal experience by identifying the network state; the network level energy saving is realized from the multi-network coordination angle, the main idea is to utilize the current network service information, determine the configuration parameters of the network energy saving through the corresponding intelligent algorithm, and realize the software energy saving of the cell, wherein the intelligent algorithm not only can be used for initializing the parameter configuration of the cell, but also can realize service prediction according to the historical service data of the cell, thereby adjusting the energy saving strategy of the cell.
For network-level energy saving, the method generally comprises the steps of service prediction, strategy generation, energy consumption evaluation and the like. Wherein, the service prediction refers to predicting the change trend of the service load of the base station by using a corresponding artificial intelligence (Artificial Intelligence, AI) algorithm based on the service load of the base station executing service; the policy generation is to determine an energy-saving policy for a corresponding cell according to a network deployment structure (such as a common coverage cell), such as a software energy-saving mode, an energy-saving time period and the like; the energy consumption evaluation is to analyze the influence of energy saving operation on KPI aiming at the energy saving strategies of the energy saving cell and the compensation cell. Because in the current network-level energy saving, after the energy saving strategy is determined, whether the energy saving strategy is feasible is determined only through energy consumption evaluation, and the service types of the execution service of the energy saving cells are not classified, various problems such as signaling overhead increase and the like can be caused when the energy saving strategy is determined according to the existing method, for example, the unnecessary transferred service is transferred to the compensation cell, and the signaling overhead is increased; or the compensation cell can not meet the QoS requirement of the energy-saving cell, so that the network quality is reduced after the related service is transferred, and the user experience is affected.
In view of the foregoing, an embodiment of the present application provides a cell energy saving method, as shown in fig. 1, including:
s101, if the base station determines that the first service is the first type service, determining a first turn-off strategy of the energy-saving cell.
The first service is a service carried by the energy-saving cell, and the first type of service is related to a first shutdown strategy.
Specifically, the cell energy saving method provided by the embodiment of the application is mainly aimed at a 5G network system. The 5G network system comprises three application scenes of enhanced mobile broadband (enhanced mobile broadband, eMBB), mass machine type communication (massive machine type of communication, mMTC) and low-delay high-reliability communication (ultra reliable low latency communication, uRLLC), and the services under different application scenes correspond to different QoS requirements, for example, mMTC services generally refer to services initiated by an Internet of things terminal of an intelligent manhole cover, an intelligent street lamp and an intelligent water meter, and the services have higher requirements on network coverage; the uRLLC service generally refers to related services such as Internet of vehicles, unmanned aerial vehicles, industrial Internet and the like, and the services have higher requirements on low time delay and high reliability of the network.
Because the energy-saving operation of the base station comprises the modes of symbol turn-off, channel turn-off, carrier turn-off and the like, and the influence of each energy-saving operation mode is different (such as the coverage area of a cell is reduced when the base station performs on-off, the available time domain resource of the cell is reduced when the base station performs symbol turn-off, and the like), when the base station adopts the energy-saving operation to save energy, whether the energy-saving operation has influence on the service carried by the energy-saving cell or not needs to be considered, so that a more flexible energy-saving strategy is formulated.
Before the base station determines the energy-saving strategy and transfers the first service of the energy-saving cell, the type of the first service can be judged, if the first service is the first type service, the corresponding energy-saving strategy of the energy-saving cell, namely the first shutdown strategy, is determined, the base station determines whether the first service affects the first shutdown strategy, and further determines whether to transfer the first service.
It should be noted that, since only a part of services may be transferred in the energy saving policy of the energy saving cell, when corresponding energy saving operations are performed, the influence of the energy saving operations on the first services still being carried by the energy saving cell needs to be considered, so as to avoid affecting the execution of the first services. The first type of service refers to high-reliability and low-delay service, and because the high-reliability and low-delay service has strong burstiness, the time domain resource of the energy-saving cell is applied to the service as much as possible so as to avoid the network quality of the service from being reduced and influence the user experience. The first shutdown policy refers to a symbol shutdown policy, and the first shutdown policy is related to the network quality of the first type of service because the symbol shutdown performed by the energy-saving cell actually limits the available time domain resources of the energy-saving cell. When the first turn-off policy does not affect the network quality of the first type service, the energy-saving cell can execute a corresponding first turn-off policy, and the first type service does not affect the energy saving of the energy-saving cell at the moment; when the first shutdown strategy affects the network quality of the first type service, in order to ensure the execution of the first type service, the energy-saving cell cannot execute the corresponding first shutdown strategy, and at this time, the first type service affects the energy saving of the energy-saving cell.
In a possible embodiment, as shown in fig. 2, step S101 includes:
s1011a, the base station determines the time domain resource occupied by the first service.
Specifically, in 5G NR, time domain resources occupied by downlink traffic channels of different services are allocated, and each time the services are dynamically allocated to scheduling of time domain resources. The granularity of allocation of time domain resources here is symbol level.
As shown in table 1 below, a time domain resource allocation table of a physical downlink shared channel (physical downlink shared channel, PDSCH) is provided, and the service type of the service can be determined according to the number of orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbols occupied by the corresponding service in the time domain resource. For example, if the mapping Type of the first service in the time domain is Type a, it may be determined that the first service is a service in an eMBB scene, if the mapping Type of the first service in the time domain is Type B, it may be determined that the number of symbols occupied by the first service is less, where the first service is a service in a ul lc scene, that is, a high-reliability and low-delay service.
TABLE 1
S in table 1 above is the symbol start position of the PDSCH, and L is the symbol length allocated to the PDSCH.
It can be determined through table 1 that the number of symbols occupied by different types of services in the time domain is different, so after determining the first service executed by the energy-saving cell, the base station can determine the service type of the first service through the time domain resource of the first service, where the time domain resource refers to the number of orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbols occupied by the first service in the time domain.
It should be noted that, the number of symbols occupied by the first service in the time domain may be determined by the field of the time domain resource allocation Time domain resource assignment in the downlink control information (Downlink Control Information, DCI), for example, the number of symbols occupied by the first service in the time domain may be determined by the field to be N symb . Of course, the person skilled in the art may determine the service type of the first service by using the class identifier (QoS class identifier, QCI) of the first service, or may determine the service type of the first service by using other manners, and the person skilled in the art may refer to the related conventional technology, which is not repeated in this embodiment of the present application.
And S1012a, if the time domain resources occupied by the first service meet the first condition, determining that the first service is the first type service.
The first condition is used for indicating the time domain resource condition occupied by the first type of service.
Specifically, the first condition herein refers to that the number of allocated symbols of the first service in N consecutive statistical periods is smaller than the second threshold. The second threshold may be set by a person skilled in the art according to needs, or may be determined according to the mapping Type of each service in the above table 1, if in the embodiment, the first service is a high-reliability low-delay service, and the mapping Type of the first service in table 1 is Type B, then the second threshold may be set to 7; where N is greater than a third threshold, which may also be set by one of ordinary skill in the art as desired.
When the base station determines that the number of symbols occupied by the first service in the continuous N statistical periods is smaller than the second threshold, the first service can be determined to be the first type service.
It should be noted that the statistical period may be one time slot.
In a possible implementation manner, step S101 may further include:
and S1011b, the base station determines that the first service is the first type service according to the first service quality information.
The first service quality information is used for indicating network quality requirements of the first service.
Specifically, the first quality of service information herein refers to QoS information corresponding to the first service, where the QoS information may be determined by signaling between networks when the terminal establishes a service, for example, in a 5G network, may be determined by signaling of a protocol data unit (protocol data unit, PDU) session resource establishment request PDU Session Resource Setup Request between an access and mobility management function (access and mobility management function, AMF) network element and a base station, where the signaling carries PDU Session Resource Setup Request Transfer IE information, and the first quality of service information corresponding to the first service may be determined by using QoS Flow Setup Request Item-QoS Flow Level QoS Parameters fields in the PDU Session Resource Setup Request Transfer IE information, so that the first service is determined to be the first service type according to the information. The signaling interaction between the AMF network element and the base station, and the establishment of the PDU Session Resource Setup Request signaling are conventional technical means in the art, and a person skilled in the art may refer to the prior art to determine the service type of the first service according to the PDU Session Resource Setup Request signaling, which is not described herein again.
It should be noted that, the steps S1011a-S1012a and S1011b provide two methods for determining the service type corresponding to the first service, and those skilled in the art may optionally determine the service type of the first service according to the need; of course, those skilled in the art may determine the service type of the first service according to other manners, which is not limited to the embodiment of the present application.
S1013, determining a first shutdown strategy of the energy saving cell.
In particular, when the first service is determined to be of the first service type, a first shutdown policy executed by the energy saving cell may be determined, so as to determine whether the first service affects execution of the first shutdown policy.
It should be noted that, since the first shutdown policy of the energy-saving cell is formulated by the base station according to the traffic loads of the energy-saving cell and the compensation cell and the corresponding traffic (the traffic carried by the energy-saving cell), the base station may determine the energy-saving policy of the energy-saving cell, that is, determine the first shutdown policy.
S102, if the first service is carried by the energy-saving cell and the base station stops executing the first turn-off strategy, the first service is transferred to the compensation cell, so that the energy-saving cell executes the first turn-off strategy.
Specifically, when the first shutdown policy affects the network quality of the first type service, in order to ensure the execution of the first type service, the energy-saving cell cannot execute the corresponding first shutdown policy, that is, the base station stops executing the first shutdown policy in the energy-saving cell. In order to realize energy saving of the energy saving cell, the first service can be transferred to the compensation cell, and the compensation cell carries the first service.
It should be noted that, when the first shutdown policy does not affect the network quality of the first type of service, the energy-saving cell may further continue to carry the first service while executing the first shutdown policy. Of course, when the network quality of the first type of service is not affected by the first shutdown strategy, the energy-saving cell can also transfer the first service to the compensation cell, so as to increase the energy-saving time period of the energy-saving cell, and further save energy for the energy-saving cell.
In a possible implementation manner, as shown in fig. 3, step S102 includes:
s1021, determining the turn-off times of the energy-saving cell executed in the target time period according to the first turn-off strategy.
Specifically, when the energy-saving cell executes the corresponding energy-saving strategy, the base station can sense the corresponding energy-saving operation of the energy-saving cell, for example, the base station can sense the symbol turn-off operation, the channel turn-off operation and the like of the energy-saving cell.
The target time period here may include a plurality of statistical periods, and the base station may determine the number of times the energy saving cell performs the first shutdown strategy in the target time period, and since the first shutdown strategy is the symbol shutdown performed by the energy saving cell, the number of times the energy saving cell adopts the symbol shutdown here.
Since the network quality of the first service may be affected when the energy-saving cell performs symbol off, and the energy-saving cell stops performing symbol off when the symbol off affects the network quality of the first service, it may be determined whether the first service affects the energy-saving cell to perform the first off policy according to the number of times the energy-saving cell performs symbol off in the target period, that is, whether the first service affects the energy saving of the energy-saving cell.
And S1022, if the turn-off times are smaller than the first threshold, stopping executing the first turn-off strategy.
Specifically, the first threshold herein may be set by those skilled in the art as needed, and the number of times of shutdown may also refer to the number of times the energy saving cell performs the first shutdown strategy.
When the number of times the energy-saving cell executes the first shutdown strategy is smaller than the first threshold, it may be determined that the base station stops the execution of the first shutdown strategy by the energy-saving cell because the first shutdown strategy affects the network quality of the first service. At this time, the first service needs to be transferred to the compensation cell so that the energy saving cell can execute the first shutdown strategy.
In one possible implementation manner, when the number of times of shutdown is greater than or equal to the first threshold, it may be determined that the first shutdown policy does not affect the network quality of the first service, and at this time, the energy-saving cell may execute the first shutdown policy in real time, so as to save energy consumption of the energy-saving cell.
In a possible implementation manner, step S102 further includes:
s1023, the base station initiates a cell reselection flow to the terminal, and configures the access priority of the compensation cell as a first priority.
The first priority is higher than the second priority, and the second priority is the access priority of the energy-saving cell.
Specifically, the step is that the network side instructs the terminal to perform a cell reselection process, that is, the terminal is accessed into the compensation cell from the current energy-saving cell through cell reselection, and the compensation cell carries the first service of the terminal.
In a particular embodiment, the base station sends a radio resource control (radio resource control, RRC) connection release message to the terminal initiating reselection of the terminal access cell. The RRC connection release message includes cell priority information for indicating a cell list corresponding to a priority frequency point, and the cell list may include a plurality of cells corresponding to the priority frequency point. For example, in the embodiment of the present application, the overlay cell may be used as the compensation cell, the capacity layer cell may be used as the energy-saving cell, and if the frequency point of the overlay cell is 2.1GHz and the frequency point of the capacity layer cell is 3.5GHz, the 2.1GHz may be used as the priority frequency point and the overlay cell under the frequency point may be used as the compensation cell.
Since the power saving cell may include a plurality of compensation cells, a plurality of cells may be included in the cell list. Further, different priorities may be set for the compensating cells according to the network quality of each compensating cell in the cell list, for example, the priority of the first compensating cell may be priority one and the priority of the second compensating cell may be priority two.
In a possible implementation manner, the base station may also set the corresponding priority according to the current traffic load of each compensating cell. The benefit of setting the cell priority according to the traffic load of the compensating cell is that: in the cell list, there may be a compensating cell with a larger current traffic load, in which case, if the compensating cell with a larger current traffic load is set as a cell with a high priority, when there are multiple terminals accessing, there may be a situation that network congestion may occur, and there may still be a possibility that access may be refused. Therefore, by setting the priority of the cell with a lower traffic load to a high priority, it is possible to reduce the case that the terminal fails in access due to a higher traffic load of the cell.
After receiving the RRC connection release message sent by the base station, the terminal can acquire the compensation cell information corresponding to the priority frequency point from the message, and reselect the cell according to the compensation cell information.
In a possible embodiment, the cell priority information in the RRC connection release message further includes a valid time, and when the terminal determines that the priority information included in the RRC connection release message is within the valid time, the terminal may select a compensating cell with a highest priority in the cell list to camp on.
Since the cell list may include a plurality of compensating cells, the terminal may first perform a camping operation on the compensating cell with the highest priority, and when the attempt to access the compensating cell with the highest priority is successful, it is not necessary to continue to attempt to access other compensating cells in the cell list. When an attempt to access fails in the highest priority cell, then an attempt may be made to access in the next lowest priority compensating cell. And so on until the terminal successfully accesses a compensating cell in the cell list.
In the embodiment of the application, the access priority of the compensation cell is higher than that of the energy-saving cell, and when the terminal initiates the access flow of the cell again, the terminal can access the compensation cell according to the access priorities of the energy-saving cell and the compensation cell to increase the energy-saving time period of the energy-saving cell when initiating the first service.
The embodiment of the method is described for the energy conservation of the first type of service carried by the energy-saving cell, and can flexibly select whether to transfer the first service to the compensation cell when the first service does not influence the energy conservation of the energy-saving cell, and can also perform symbol turn-off operation on symbols originally occupied by the first service when determining to transfer the first service to the compensation cell, thereby increasing the energy-saving time period of the energy-saving cell. Meanwhile, the embodiment of the application also sets the access priority of the compensation cell, and can preferentially transfer the first service to the compensation cell with better network quality, thereby ensuring the network quality of the first service and improving the user experience.
In a possible implementation manner, when the energy-saving cell carries the second service and the second service is the second type service, the base station may further determine a second shutdown policy of the energy-saving cell at this time, and determine whether the second shutdown policy affects execution of the second service. The energy saving cell may also be stopped from executing the second shutdown policy when the second shutdown policy affects the execution of the second service. The second service may be a service with a high requirement on network coverage, such as an eMBB service, and the second shutdown policy is a channel shutdown policy adopted by the energy-saving cell.
Since the coverage area of the energy-saving cell may be reduced when the energy-saving cell takes the channel to be turned off, whether to affect the second service needs to be considered before the energy-saving cell takes the channel to be turned off, so as to determine whether to execute the second turn-off policy. Of course, when the energy-saving cell carries other types of services, the energy-saving operation (such as carrier off) adopted by the energy-saving cell can be combined with the services carried by the energy-saving cell to determine whether to execute the corresponding energy-saving strategy.
It should be noted that, here, according to different QoS of the bearer service of the energy-saving cell, cells with different network quality may be determined as compensation cells, for example, the ul lc service requires high reliability and low latency, and the eMBB requires wide coverage, so that different compensation cells may be determined for the two types of services, so that after the two types of services are transferred to the compensation cells, the compensation cells can meet the QoS requirements of the two types of services.
The cell energy saving method provided by the embodiment of the application comprises the following steps: if the base station determines that the first service is the first type service, determining a first turn-off strategy of the energy-saving cell; the first service is a service borne by the energy-saving cell, and the first type of service is related to a first shutdown strategy; and if the first service is carried by the energy-saving cell and the base station stops executing the first shutdown strategy, transferring the first service to the compensation cell so that the energy-saving cell executes the first shutdown strategy. The embodiment of the application combines the service type of the energy-saving cell bearing service with the related energy-saving strategy, and when the energy-saving cell bearing service does not influence the execution of the energy-saving strategy, the energy-saving cell can continue to bear the service; when the service carried by the energy-saving cell affects the execution of the energy-saving strategy (the execution of the energy-saving strategy leads to the reduction of the network quality of the service carried by the energy-saving cell), the energy-saving strategy cannot be continuously executed, and the service carried by the energy-saving cell can be transferred to the compensation cell at the moment, so that the energy-saving cell can execute the energy-saving strategy and simultaneously avoid the reduction of the network quality of the service carried by the energy-saving cell.
As shown in fig. 4, an embodiment of the present application provides a base station 20, including:
a processing module 201, configured to determine a first shutdown policy of the energy-saving cell when determining that the first service is a first type service; the first service is a service carried by the energy-saving cell, and the first type of service is related to a first shutdown strategy.
And the compensation module 202 is configured to, when the first service is carried by the energy-saving cell and the base station stops executing the first shutdown policy, transfer the first service to the compensation cell, so that the energy-saving cell executes the first shutdown policy.
