It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

FIG. 1 is a flowchart showing a method for extending a standby power supply time of a base station according to an embodiment of the present invention, where the process includes the following steps:

Step S10: When the base station detects that the main power source is powered off, the base station reports to the base station control module that the base station main power is off.

The base station is connected to the main power supply and the backup power supply of the mains, and the base station itself has relevant hardware to detect whether the power supply is powered off. There are a variety of power outages, such as instantaneous power down, reset, and so on. In an embodiment, the base station control module may be a base station controller, and the base station reports the main power failure message to the base station controller regardless of the form of the main power supply being powered off.

Step S20: The base station control module reduces the power consumption of the cell according to the service priority level according to the message that the base station is powered off.

In an embodiment, the relevant parameters can be configured by the operation and maintenance system OMC-R and made effective at the base station control module. The base station is responsible for the initiation of the event as the trigger source of the process, that is, it reports the information to the base station control module after detecting the change of the main power supply, and the base station control module passively processes the data according to the parameters set by the OMC-R. The power consumption is controlled, and the information about the current running status of the base station is sent to the OMC-R of the operation and maintenance system for the operation and maintenance personnel to view and retrieve. In the embodiment of the present invention, the parameters of the base station and the base station control module are set by the OMC-R, so that the power consumption of the cell is reduced according to the service priority level when the primary power of the base station is powered down, and the running time of the base station can be effectively extended.

In the foregoing step S20, reducing the power consumption of the cell according to the service priority level may include: first reducing the power consumption of the cell with the lowest priority of the service, and then gradually controlling the energy consumption of the cell with the higher priority, and finally retaining only the key carrier to provide basic service. For example, the base station control module selects a part of the base station with a lower service level according to the parameters set in the OMC-R in advance, and reduces the power consumption of the base station by reducing the power supply voltage, turning off the power amplifier, and the like, and reporting the operation result to the OMC- R's status management related module to notify maintenance personnel.

In an embodiment, the reducing the power consumption of the cell may include:

For users who must terminate service in the cell, try to migrate them to other cells with higher service levels to avoid business interruption. For example, if a user in the selected cell is receiving the service and the power consumption control for the cell determines that the user is affected according to the set parameters, the user is attempted to migrate to other devices not in the current control. The cell is designed to minimize the interruption of service caused by the operation. If the migration fails, the user can wait until the user actively disconnects after completing the service, and the power control is started.

In another embodiment, the reducing the cell power consumption may include:

If the key carrier of the base station fails, it searches for a suitable carrier to restore the power supply state, and replaces the original key carrier with the carrier as the new key carrier to continue to provide the most basic service. For example, in the period when the base station power consumption control power supply is not exhausted, if a carrier BCCH (Broadcast Control Channel) carrier fails, the corresponding cell needs to report the fault to the base station control module, and the base station control module One other carrier is selected in the cell, and the original BCCH carrier is replaced by the existing process, and the original carrier is controlled by power consumption.

In still another embodiment, the reducing the cell power consumption may include:

If the base station resets, it is generated by the base station control module according to the base station after it returns to normal. The operating state parameter set before reset is restored to the working state before resetting; if the base station control module is reset, after it returns to normal, the power-off message is reported, and the power consumption of the cell is repeatedly reduced according to the service priority level. For example, in the period when the main power failure alarm occurs but the backup power is not exhausted, if the base station resets, after it returns to normal and re-establishes the communication link with the base station control module, the base station control module is based on the stored base station. The working state before reset restores the base station to the corresponding state. If the base station control module is reset, after it returns to normal, the base station re-reports the power-off alarm message, and repeats the above-mentioned power consumption control process again.

In an embodiment, the detecting, by the base station, that the main power supply is powered off includes:

It is judged whether the power-off is caused by the instantaneous interruption of the utility power supply system, and if not, the message that the base station main power supply is powered off is reported to the base station control module. For example, the base station detects the change of the main power supply on and off, and reports that the main power supply is powered off and reports the main power failure alarm notification to the base station control module. After receiving the notification message, the base station control module sends the message to the alarm management related module of the OMC-R on the one hand, and determines whether the related function switch is turned on on the other hand (the function switch can be set to two levels of the system and the base station, for each base station Only when both switches are open means the function is active). If the switch is off, no processing is done, the process ends; if the switch is open, the base station control module sets the power-off confirmation timer to enter the power-off confirmation process. If the base station detects the main power recovery of the base station within the T1 time period preset by the power failure confirmation timer, the power failure recovery processing flow shown in Figure 2 is performed. If the base station detects that the base station main power is not restored, the base station control module does nothing and waits for T1 to time out. If the timer preset T1 times out, the base station control module sets the power consumption control timer to enter the base station power consumption control flow. In the T2 time period set by the power control timer, the base station control module selects a part of the base station with a lower service level according to the parameters set by the OMC-R in advance, and reduces the base station by reducing the power supply voltage and turning off the power amplifier. Power consumption, and report the operation result to the state management related module of OMC-R.

Referring to FIG. 2, a flowchart of processing when a base station main power supply is powered off is restored according to an embodiment of the present invention. The process includes the following steps: The base station reports the main power failure alarm recovery notification to the base station control module;

After receiving the notification message, the base station control module checks all the cells of the base station. If there is limited power consumption control, the message is sent to the alarm management related module of the OMC-R to inform the user that the power failure has been recovered, and the power supply voltage is restored. , Turn on the power amplifier, etc., and return it to normal operation, and report the operation result to the state management related module of OMC-R.

Determine whether the related function switch is turned on (the function switch can be set to two levels of system and base station, only two switches are turned on for each base station to indicate that the function is valid). If the switch is off, no processing is done, the process ends; if the switch is on, the base station control module will do the following: If power is restored during the T1 timer time, the process ends after killing timer T1. If power is restored during the T2 timer time, the process ends after killing timer T2. If the main power is restored after the T2 timer expires but before the base station is powered off, the process ends directly after completing the above steps.

If the primary power is restored after the base station is powered off, the base station reports the primary power restoration message to the base station control module after the base station and the base station control module are normally established. After receiving the message, the base station control module clears the previously set power to the base station. The status related to the control is consumed, and the alarm recovery message is reported to the OMC-R state management related module.
