Background
With the rapid development of communication technology, the corresponding power consumption also increases. The current design of the shutdown-type energy-saving feature mainly shuts down a power amplifier (PowerAmplifier, abbreviated as PA) of the RU module, but the power consumption of the RU module is still high due to the requirement of the current network service (requiring fast wake-up) and the current architecture situation of the Radio Unit (RU) module of the base station. As shown in fig. 1, an example of a current RU circuit, which implements a sleep mode of an RU module, can only sleep in a single sleep mode when the RU module satisfies a condition of the sleep mode, for example: in the conventional RU circuit, only the first functional unit can be turned off fixedly, and the power supply set corresponding to the first functional unit is not turned off (the power consumption of the power supply set is relatively large), while the second functional unit, the power supply set corresponding to the second functional unit, and the first secondary power supply and the second secondary power supply are always in a normal state, and the flexibility is poor, so that the power consumption of the RU module after dormancy is still high.

Referring to fig. 3, an embodiment of a sleep method of a radio frequency unit according to an embodiment of the present invention is illustrated in detail as follows:
The RU according to the embodiment of the present invention is actually an RU module of a base station, and when a carrier of a certain frequency band is turned off and an RU carrying the carrier is in an idle state, the base station acquires a current service state parameter, where the service state parameter may be acquired locally by the base station or acquired by the base station through a server, and this is not particularly limited herein. The service state parameter refers to the traffic volume, the service level, and the like currently assumed by the RU.
Different from the prior art, the base station determines the sleep mode of the RU according to the service state parameters, wherein the sleep mode comprises a simple sleep mode and a deep sleep mode, and therefore, the sleep mode is divided in a grading manner, the energy-saving requirements under different low-service scenes can be met, and in practical application, equipment with higher service requirements is started in the low-service scenes; and starting a deep sleep mode for equipment with higher requirements on energy-saving effect in a low-service scene.
When the base station determines the sleep mode of the RU, for example: and in the simple sleep mode or the deep sleep mode, the base station controls the RU to sleep according to the simple sleep mode or the deep sleep mode, so that the power consumption of the RU is flexibly and deeply reduced, and the efficiency of reducing the power consumption is improved.
In some possible implementations, the base station controls, through RU circuitry, the RU to sleep in the simple sleep mode or the deep sleep mode.
It can be seen that the base station realizes a simple sleep mode or a deep sleep mode through the RU circuit, and controls the RU sleep according to the simple sleep mode or the deep sleep mode, which is simple to operate and high in efficiency.
In other possible implementations, the RU circuitry includes a processing unit, a power supply, a control unit, and a functional unit; wherein the processing unit is connected with the control unit, and the power supply is connected with the control unit and the functional unit; the processing unit is used for analyzing a switching signal of the RU circuit and sending the switching signal to the control unit; the control unit is used for receiving the switching signal sent by the processing unit and controlling the power supply and the functional unit to be switched on or switched off according to the switching signal.
Different from the prior art, the RU circuit includes a control unit and a processing unit in addition to a power supply and a functional unit, and the switching signal of the RU circuit is analyzed by the processing unit, and the power supply and the functional unit are controlled to be turned on or off by the control unit according to the switching signal, so that a simple sleep mode or a deep sleep mode is realized.
In other possible implementations, the control unit includes a first control unit and a second control unit, the functional unit includes a first functional unit and a second functional unit, and the power supply includes a first power supply and a second power supply.
As can be seen, a first power supply is connected with the first control unit and the first functional unit, and the first power supply is controlled by the first control unit to control the switch of the first functional unit; the second power supply is connected with the second control unit and the second functional unit, and the second control unit controls the second power supply to further control the switch of the second functional unit. Of course, in other embodiments, the first power source and the second power source may be integrated into a single power source, which is not limited herein.
In practical applications, the RU circuit is divided into four parts, for example: a processing unit, a control unit, functional units (such as a first functional unit capable of waking up in a second level and a second functional unit capable of waking up in a clock level), and a power supply. Wherein, the processing unit (for example: a chip for detecting the switch signal) always keeps the power supply state, and a control switch is arranged at the port of the control unit, thereby controlling the circuit through the control switch. Wherein, control switch sets up in the front end of power conversion circuit, for example: in the deep sleep mode, after the control switch is closed, the output end of the power conversion circuit and most circuits of the power conversion circuit are all turned off, and only the control circuit of the power conversion circuit is reserved.
In other possible implementations, when the sleep mode of the RU is the simple sleep mode, the controlling, by the base station, the RU to sleep in the simple sleep mode by an RU circuit includes: the base station controls the first power supply to be turned off through the first control unit, so that the first functional unit is turned off.
In other possible implementations, when the sleep mode of the RU is the deep sleep mode, the controlling, by the base station, the RU to sleep in the deep sleep mode by an RU circuit includes: the base station analyzes a current switch signal of the RU circuit through the processing unit, and controls the first power supply to be turned off through the first control unit according to the switch signal, so that the first functional unit is turned off; and controlling to turn off the second power supply through the second control unit according to the switching signal, so as to turn off the second functional unit. Wherein the processing unit can obtain the current switching signal of the RU circuit through the communication interface and/or the power interface.
In practical applications, for example: when the network traffic is reduced, the carrier wave of a certain frequency band is turned off, and the RU bearing the carrier wave is in an idle state, then the RU enters a sleep mode according to the sleep mode determined by the base station:
as shown in fig. 4, when the base station determines that the sleep mode of the RU is the simple sleep mode, the first control unit immediately turns off the first functional unit capable of waking up quickly and the corresponding first power supply, and the second functional unit and the corresponding second power supply are in the normal state, in some scenarios, the first power supply set (including at least one power supply) is connected between the first power supply and the first function, and when the first power supply is turned off, the corresponding first power supply set is also turned off, so as to effectively reduce power consumption, and the measured data shows that, in the simple sleep mode, the power consumption is saved by about 20% compared with the prior art.
As shown in fig. 5, when the base station determines that the sleep mode of the RU is the deep sleep mode, the first functional unit capable of waking up quickly and the corresponding first power source are turned off immediately by the first control unit; and meanwhile, the service load of the network is judged, when the service load is lower than a certain threshold a (a is set by the base station or is user-defined, and is not specifically limited), the second functional unit and the corresponding second power supply are further turned off through the second control unit, in some scenes, a second power supply set (comprising at least one power supply) is connected between the second power supply and the second functional unit, and when the second power supply is turned off, the corresponding second power supply set is also turned off, so that the power consumption is effectively reduced. Therefore, the base station transmits the switch signal in an overlapping manner through the RU power supply circuit, and the processing unit analyzes the switch signal of the RU circuit, so that the second control unit controls the second functional unit to realize the deep sleep mode. Measured data show that, compared with the prior art, the power consumption is saved by about 80% in the deep sleep mode, for example: the control switch is arranged at the port of the second control unit and is arranged at the front end of the second power supply conversion circuit, so that the static power consumption of the power supply circuit can be reduced to about 6W from 16W, the power consumption is saved, in addition, the switching signal of the RU circuit is multiplexed with the power supply line, the physical communication port is not required to be added, and the cost is saved.
Referring to fig. 6, an embodiment of a wake-up method of a radio frequency unit according to an embodiment of the present invention is illustrated, and a specific flow is as follows:
In the embodiment of the present invention, the base station may obtain the service state parameter locally, or may obtain the service state parameter through the server, which is not specifically limited herein, where the service state parameter is used to determine whether to wake up an RU in the sleep mode. The service state parameter refers to the traffic volume, the service level, and the like currently assumed by the RU.
Different from the prior art, when the base station determines to wake up the RU according to the service state parameters, the base station wakes up the RU according to the wake-up mode corresponding to the simple sleep mode or the deep sleep mode, so that the RU is woken up flexibly and quickly, and the efficiency of recovering services is effectively improved.
In some possible implementations, the controlling, by the base station, the RU to wake up the RU in an awake mode corresponding to the simple sleep mode or the deep sleep mode includes:
and the base station controls the RU to wake up the RU according to the wake-up mode corresponding to the simple sleep mode or the deep sleep mode through an RU circuit.

and the base station controls the first power supply to be turned on through the first control unit, so that the first functional unit is turned on.
Therefore, when the sleeping mode of the RU is the simple sleeping mode, the base station controls to turn on the first power supply through the first control unit, so as to turn on the first functional unit, thereby waking up the RU flexibly and quickly, and effectively improving the efficiency of recovering services.
In other possible implementations, when the sleep mode of the RU is a deep sleep mode, the controlling, by the base station, the RU to wake up the RU according to a wake-up mode corresponding to the deep sleep mode by an RU circuit includes: the base station analyzes a current switch signal of the RU circuit through the processing unit, and controls to turn on the first power supply through the first control unit according to the switch signal, so that the first functional unit is turned on; and controlling to turn on the second power supply through the second control unit according to the switching signal, so as to turn on the second functional unit.
It can be seen that, when the RU sleeping mode is the deep sleep mode, the base station parses the current switch signal of the RU circuit through the processing unit, and controls to turn on the first power supply according to the switch signal through the first control unit, so as to turn on the first functional unit, and the base station parses the current switch signal of the RU circuit through the processing unit, and controls to turn on the second power supply according to the switch signal through the second control unit, so as to turn on the second functional unit, thereby waking up the RU flexibly and quickly, and effectively improving the efficiency of recovering services.
In practical applications, as shown in fig. 7, for example: when the network telephone traffic is reduced, when the sleep mode of the RU is the simple sleep mode, if the base station determines to wake up the RU, the first control switch is turned on, so that the first power supply and the first functional unit are turned on, and the RU in the simple sleep mode can be quickly woken up in a second level. As shown in fig. 8, when the sleep mode of the RU is the deep sleep mode, if the base station determines to wake up the RU, the first control switch is turned on, so as to turn on the first power supply and the first functional unit, and the second control switch is turned on, so as to turn on the second power supply and the second functional unit, so that the RU in the deep sleep mode can be quickly woup in a minute-level manner, and the service can be quickly resumed.
In summary, when an RU is in an idle state, a base station does not directly control the RU to sleep according to a single sleep mode, but first obtains a service state parameter of a current base station, and determines a sleep mode of the RU according to the service state parameter, where the sleep mode includes a simple sleep mode and a deep sleep mode, and the base station controls the RU to sleep according to the simple sleep mode or the deep sleep mode. Therefore, the simple sleep mode or the deep sleep mode is determined according to the service state parameters of the current base station, so that the power consumption of the RU is flexibly and deeply reduced according to the service state parameters of the current base station, and the efficiency of reducing the power consumption is effectively improved.
