Description

Energy-saving method and device and readable storage medium

Technical Field

The present disclosure relates to the field of communications, and in particular, to an energy saving method and apparatus, and a readable storage medium.

Background

With the development of mobile communication networks, the energy consumption of wireless networks is increasing, and the demands of operators on energy conservation and consumption reduction of base stations are also pressing. Therefore, the base station energy saving technology is a hot spot for research in the industry.

At present, various base station energy saving schemes are proposed in the industry, and the basic principle is to close part of hardware resources of the base station when the network is idle, so that the energy saving effect is achieved. The common technology is symbol turn-off or time slot turn-off technology, namely, the power amplification unit of the base station is turned off in the idle time without service data transmission through the two technologies, and the power amplification unit of the base station is turned on in the time with service data transmission.

However, in the existing symbol turn-off or slot turn-off technology, on one hand, since the turn-off duration of the hardware resource of the Active Antenna Unit (AAU) is limited to the length of a single data symbol or slot, and the arrival of the service data has randomness, the number of symbols or slots without service data transmission in the existing network is limited, the turn-off duration of the hardware resource is short, and the energy saving effect is limited. On the other hand, the existing energy-saving scheme adopts uniform hardware turn-off duration, the AAU can only execute energy-saving processing by using data symbols or time slots as unit time length, and cannot consider the transmission delay requirements of different types of services to influence service performance. In addition, the hardware resources switched off by the existing energy-saving scheme are only limited to the radio frequency processing unit of the AAU, and the switched-off hardware resources are limited, so that the problem of limited energy-saving effect also exists. In summary, the energy saving method provided by the prior art has a limited energy saving effect and affects the service performance.

The AAU is mainly responsible for conversion of baseband signals and radio frequency signals and transceiving processing functions of the radio frequency signals.

As shown in fig. 1, the base station is internally provided with an AAU and a BBU, and the AAU can perform data interaction with the BBU. For example, in the embodiment of the present disclosure, the AAU can control the hardware resources inside the target base station to be turned on or off according to the energy saving state of the target base station, and can determine whether there is service data to be transmitted in a unit time length according to the service scheduling information acquired from the BBU and the service request information acquired from the UE.

2. Indoor baseband processing unit

An indoor Base Band Unit (BBU) belongs to a part of a Base station device. The BBU is mainly responsible for baseband protocol processing and provides an interface with the core network.

Exemplarily, in the embodiment of the present disclosure, the BBU can obtain service parameter information of the target base station and determine the energy saving state of the target base station according to the service parameter information.

As shown in fig. 3, the hardware resources inside the BBU mainly include a baseband processing unit, an interface unit, and the like.

The base band processing unit at the BBU side is responsible for completing the high-level base band protocol processing function, and the interface unit is responsible for interaction with the AAU and the core network.

The energy saving method and the energy saving device provided by the embodiment of the disclosure can be applied to operators to save energy for base station equipment. In a specific application scenario of the embodiment of the present disclosure, the energy saving device periodically obtains service parameter information of a current base station, determines an energy saving state of the base station, and controls a corresponding hardware resource to be in a shutdown state at an initial time of a period; when service data need to be transmitted, corresponding hardware resources are started to keep normal operation of the service; and when no service data needs to be transmitted, continuously keeping the corresponding hardware resources in the off state. Therefore, the base station equipment provided with the energy-saving device can improve the energy-saving effect of the base station and reduce the time delay of service transmission while keeping the normal operation of the service.

The technical scheme provided by the disclosure is specifically explained in the following with the accompanying drawings of the specification.

In different application scenarios, the AAU and the BBU may be independent devices, or may be integrated in the same device, which is not specifically limited by the present disclosure.

When the AAU and the BBU are integrated in the same device, the communication mode between the AAU and the BBU is the communication between the internal modules of the device. In this case, the communication flow between the AAU and the BBU is the same as the communication flow between the AAU and the BBU when they are independent of each other.

In the following examples provided by the present disclosure, the present disclosure is illustrated with the AAU and BBU set independently of each other as examples.

Fig. 4a is a flow diagram illustrating a method of saving power according to an exemplary embodiment. In some embodiments, the above power saving method can be applied to the AAU and BBU shown in FIGS. 2-3 or other similar devices.

Exemplarily, as shown in fig. 4a, a schematic flow chart of an energy saving method provided by an embodiment of the present disclosure includes the following steps:

s401, the BBU obtains service parameter information of the target base station in a first period.

The service parameter information includes a service volume parameter and a service type parameter. The value of the traffic parameter is the sum of the number of service transmission requests and the number of access requests initiated by the target base station in the first period. The value of the service type parameter is the number of the delay sensitive services initiated by the target base station in the first period.

It can be understood that the number of service transmission requests, the number of access requests, and the number of delay-sensitive services initiated by the target base station in the first period can be obtained from a database of the target base station server. The duration of the period may be preset manually, which is not limited by this disclosure.

S402, the BBU determines the energy-saving state of the target base station in the second period according to the service parameter information.

The starting time of the second period is the ending time of the first period, and the second period comprises at least one unit time length.

Optionally, the energy saving state of the target base station includes a first energy saving state, a second energy saving state, and a third energy saving state. And, the values of the unit time lengths corresponding to different energy saving states are also different, which is detailed in the following S404. When the energy-saving state of the target base station is a first energy-saving state, a target unit controlled by the target base station is a power amplifier unit; when the energy-saving state of the target base station is a second energy-saving state, a target unit controlled by the target base station is a radio frequency processing unit; and when the energy-saving state of the target base station is the third energy-saving state, the target units controlled by the target base station are the baseband processing unit and the radio frequency processing unit. The baseband processing unit is a baseband processing unit included in the AAU and/or a baseband processing unit included in the BBU.

Optionally, the BBU determines the energy saving state of the target base station according to the size relationship between the service type parameter and the service type threshold, the size relationship between the service volume parameter and the service volume threshold, and the size relationship between the duration of the size relationship and the time threshold.

Optionally, the traffic threshold includes a first traffic threshold, a second traffic threshold and a third traffic threshold. Wherein the first traffic threshold is greater than the second traffic threshold, and the second traffic threshold is greater than the third traffic threshold.

Optionally, the time threshold includes a first time threshold, a second time threshold and a third time threshold. The first time threshold is smaller than the second time threshold, and the second time threshold is smaller than the third time threshold.

Illustratively, the energy saving state of the target base station is determined according to the service parameter information and three preset thresholds in four cases.

In case one, if the service type parameter is greater than the service type threshold, the energy saving state of the target base station is determined to be the first energy saving state.

And in the second situation, if the service type parameter is less than or equal to the service type threshold, the service volume parameter is less than the first service volume threshold and is greater than or equal to the second service volume threshold, and meanwhile, the duration of the service volume parameter which is less than the first service volume threshold and is greater than or equal to the second service volume threshold is greater than the first time threshold, determining that the energy-saving state of the target base station is the first energy-saving state.

And thirdly, if the service type parameter is less than or equal to the service type threshold, the service volume parameter is less than the second service volume threshold and is greater than or equal to the third service volume threshold, and meanwhile, the duration of the service volume parameter which is less than the second service volume threshold and is greater than or equal to the third service volume threshold is greater than the second time threshold, determining that the energy-saving state of the target base station is the second energy-saving state.

And fourthly, if the service type parameter is less than or equal to the service type threshold, the service volume parameter is less than or equal to the third service volume threshold, and meanwhile, the duration of the service volume parameter less than or equal to the third service volume threshold is greater than the third time threshold, determining that the energy-saving state of the target base station is the third energy-saving state.

It is to be understood that the sizes of the traffic type threshold, the traffic volume threshold and the time threshold may be preset manually and stored in the database on the AAU side, which is not limited by the present disclosure.

Optionally, after determining the energy saving state of the target base station in the second period, the BBU generates energy saving state indication information.

S403, the BBU sends the energy-saving state indication information to the AAU.

Optionally, the energy saving status indication information carries an energy saving status identifier of the base station. For example, corresponding to the case that the three energy saving states in S402 are the first energy saving state, the second energy saving state and the third energy saving state, the marks 00, 01 and 10 respectively represent the first energy saving state, the second energy saving state and the third energy saving state.

And S404, the AAU executes corresponding energy-saving operation according to the energy-saving state indication information.

It can be understood that the AAU determines, according to the energy saving state identifier of the base station carried in the energy state indication information, which of the three energy saving states the energy saving state of the target base station is in the second period.

The AAU controls the target unit to be turned on or off according to different energy saving states to execute corresponding energy saving operations.

Optionally, corresponding to the three energy saving states in S402 being the first energy saving state, the second energy saving state, and the third energy saving state, the following description is given with reference to three specific examples:

in case one, the target base station is in the first energy saving state.

At this time, the AAU turns off its internal power amplifier unit at the initial time of the second period, and determines that the first duration is a unit duration, which is the duration of one data symbol.

Further, the AAU acquires service data scheduling information and service request information of the target base station within the duration of the second period. The service data scheduling information is used for indicating the transmission time of the service data, and the service request information is used for requesting the terminal to transmit the service data.

It can be understood that, the AAU can determine whether there is service data to be transmitted in each unit time length according to the service data scheduling information and the service request information.

Optionally, if there is service data to be transmitted in a unit time length, the AAU starts the power amplifier unit to ensure normal operation of the service. If no service data need to be transmitted in the unit time length, the AAU continuously keeps the power amplification unit in a turn-off state.

And in case two, the target base station is in a second energy-saving state.

At this time, the AAU turns off its internal radio frequency processing unit at the initial time of the second period, and determines that the second duration is a unit duration, which is the duration of one data subframe.

Furthermore, the AAU acquires the service data scheduling information and the service request information of the target base station within the duration of the second period, and determines whether there is service data to be transmitted within each unit time length.

Optionally, if there is service data to be transmitted in a unit time length, the AAU starts the radio frequency processing unit to ensure normal operation of the service. If no service data needs to be transmitted in the unit time length, the AAU continuously keeps the radio frequency processing unit in a turn-off state.

And in case three, the target base station is in a third energy saving state.

At this time, the AAU turns off its internal baseband processing unit and radio frequency processing unit at the initial time of the second period, and determines that the third duration is a unit duration, which is the duration of one data frame.

Furthermore, the AAU acquires service data scheduling information and service request information of the target base station within the duration of the second period, and determines whether there is service data to be transmitted within each unit duration.

Optionally, if there is service data to be transmitted in a unit time length, the AAU starts the baseband processing unit and the radio frequency processing unit to ensure normal operation of the service. If no service data needs to be transmitted in the unit time length, the AAU continuously keeps the baseband processing unit and the radio frequency processing unit in a turn-off state.

It should be noted that, when the AAU controls the baseband processing unit to turn on or off, the baseband processing unit on the AAU side may be only turned on or off, or the baseband processing units on the AAU and the BBU side may be simultaneously turned on or off. The shutdown method of the baseband processing unit may be determined based on requirements or device support capability, and may be preset on the AAU and BBU sides, for example.

It is understood that the correspondence between the three energy saving states and the three unit time lengths, and the target unit to be controlled may be stored in advance on the AAU side.

Based on the technical scheme, the energy-saving state of the target base station in the current period and the target unit controlled correspondingly are determined by acquiring the service parameter information of the target base station in the last period. Meanwhile, according to whether service data is transmitted in each unit time length in the current period, when no service data needs to be transmitted in the unit time length, the target unit is turned off, and the energy-saving state is entered; and when service data need to be transmitted in the unit time length, starting the target unit, entering a normal working state, and keeping the normal operation of the service. The lower the grade of the energy-saving state is, the less the hardware resources are turned off, and the smaller the hardware starting time delay is, so that the faster the conversion between the energy-saving state and the normal working state is, the better the performance of the time delay sensitive service is; the higher the energy-saving state grade is, the longer the corresponding turn-off time is, the more the hardware resources are turned off, and the greater the energy-saving benefit is. Therefore, aiming at different base station states and service types, the method and the device can improve the energy-saving effect of the base station and simultaneously reduce the time delay of service transmission.

Specifically, with reference to fig. 4b, for obtaining the delay sensitive service number in the embodiment of the present disclosure, the embodiment of the present disclosure specifically includes:

and S411, the AAU receives the service request information sent by the terminal.

Optionally, the service request information sent by the terminal carries a service type identifier, where the service type identifier is used to indicate a service type to which the service belongs.

Illustratively, the service type identifier may include 0 and 1. If the service type identifier is 0, the service type of the service currently requested by the terminal is represented as a non-delay sensitive service; if the service type identifier is 1, it indicates that the service type of the service currently requested by the terminal is a delay sensitive service. The above is merely an exemplary example, and the present disclosure does not limit the representation form of the specific service type identifier.

S412, the AAU forwards the service request information to the BBU.

S413, the BBU analyzes the received service request information to obtain the service type identification.

Optionally, if the service type identifier obtained after the BBU analyzes the service request information is the delay-sensitive service identifier, the BBU determines that the service request information is the delay-sensitive service request information.

Illustratively, corresponding to the example of S411, if the service type identifier obtained by the BBU is 1, it indicates that the service request information is delay-sensitive service request information.

And S414, the BBU takes the total number of the delay sensitive service request messages sent by all the terminals of the target base station in the first period as a service type parameter.

Optionally, the BBU stores the service type parameter in a server of the target base station.

Based on the above steps S411 to S414, the embodiment of the present disclosure can analyze the service request information sent by the terminal in the target base station through the BBU, and count the number of the delay-sensitive services initiated by the target base station in the period.

Specifically, with reference to fig. 4c, for the AAU to acquire the service data scheduling information of the target base station, the embodiment of the present disclosure specifically includes:

s421, the BBU schedules the service data, and determines service data scheduling information.

Optionally, after receiving the service request information sent by the terminal, the BBU determines the service data transmission time of the service. Wherein, the time of the service data transmission is the duration of continuous data symbols, data subframes or data frames.

It can be understood that the BBU schedules the service data to be transmitted within the duration of one or more continuous data symbols, data subframes, or data frames, so that there is no service data to be transmitted in the remaining data symbols, data subframes, or data frames, thereby achieving data aggregation in a certain time domain, increasing the time length in the target base station for which the target unit can be turned off, and improving the energy saving effect.

S422, BBU sends service data scheduling information to AAU.

The service data scheduling information includes transmission time of the service data.

And S423, the AAU determines whether the service data needs to be transmitted in each unit time length according to the service data scheduling information.

Optionally, the AAU determines whether there is service data to be transmitted in a corresponding unit time length in different energy saving states according to the transmission time of the service data included in the service data scheduling information.

And S424, the AAU controls the on or off of the target unit according to whether the service data needs to be transmitted in each unit time length.

Optionally, corresponding to the case that the three energy saving states in S402 are the first energy saving state, the second energy saving state, and the third energy saving state, the following description is given by combining the three specific cases:

in case one, the target base station is in the first energy saving state.

If the AAU determines that service data needs to be transmitted in the current unit time, the AAU starts a power amplification unit to ensure the normal operation of the service. If no service data need to be transmitted in the unit time length, the AAU continuously keeps the power amplification unit in a turn-off state.

And in case two, the target base station is in a second energy-saving state.

If the AAU determines that service data needs to be transmitted in the current unit time length, the AAU starts a radio frequency processing unit to ensure the normal operation of the service. If no service data needs to be transmitted in the unit time length, the AAU keeps the radio frequency processing unit in a turn-off state.

And in case three, the target base station is in a third energy-saving state.

If the AAU determines that service data needs to be transmitted in the current unit time length, the AAU starts the baseband processing unit and the radio frequency processing unit to ensure the normal operation of the service. If no service data needs to be transmitted in the unit time length, the AAU continuously keeps the baseband processing unit and the radio frequency processing unit in a turn-off state.

Based on the above steps S421-S423, in the embodiment of the present disclosure, the BBU can converge data in a certain time domain, increase the time length that a target unit in a target base station can be turned off, improve the energy saving effect, and enable the AAU to determine whether data needs to be transmitted in each unit time length. And further, the target base station realizes energy conservation and simultaneously guarantees normal operation of services.

Specifically, with reference to fig. 4d, for the AAU to acquire the service request information of the target base station, the embodiment of the present disclosure specifically includes:

and S431, the terminal of the target base station sends the service request information to the AAU.

It will be appreciated that the terminal sends service request information to the AAU, i.e. indicating that the terminal has service data to transmit.

And S432, the AAU determines that the service data needing to be transmitted exists in the current unit time length according to the service request information.

It should be noted that, after receiving the service request information sent by the terminal, the AAU can determine the service data that needs to be transmitted in the current unit time length without interacting with the BBU. Therefore, the transmission detection of the service data can be completed in the AAU, and the service data does not need to be forwarded to the BBU for detection, so that the transmission detection of the service data is faster, the target unit can be started more timely, and the time delay of service transmission in an energy-saving state is shortened.

And S433, opening the target unit by AAU control.

in case one, the target base station is in the first energy saving state.

At this moment, the AAU starts the power amplification unit to ensure the normal operation of the service.

And in case two, the target base station is in a second energy-saving state.

At this time, the AAU starts the radio frequency processing unit to ensure the normal operation of the service.

And in case three, the target base station is in a third energy saving state.

At this time, the AAU starts the baseband processing unit and the radio frequency processing unit to ensure the normal operation of the service.

It is understood that the baseband processing unit controlled to be turned on by the AAU at this time is a baseband processing unit included in the AAU and/or a baseband processing unit included in the BBU. Specifically, when the baseband processing unit controlled by the AAU includes the baseband processing unit included in the BBU, the AAU may send the received service request information to the BBU to instruct the BBU to start the baseband processing unit, and resume normal operation.

Based on the above steps S431 to S433, in the embodiment of the present disclosure, in the energy saving state, the transmission detection of the service data may be completed in the AAU, and the service data does not need to be forwarded to the BBU for re-detection, so that the transmission detection of the service data is faster, and thus the target unit can be started more timely, and the time delay of the service transmission in the energy saving state is shortened. And further, the target base station can save energy and simultaneously guarantee the normal operation of the service.
