Background
The public mobile communication base station is an interface device for accessing mobile equipment to the internet, and refers to a radio transceiver device for information transmission between a mobile telephone terminal and a mobile communication switching center in a certain radio coverage area. The mobile communication base stations can not work with electric energy support, and at present, each mobile communication base station usually adopts the commercial power provided by an electric power department as electric energy and is also provided with a storage battery for emergency when the commercial power is cut off. However, as the capacity of the self-contained storage battery is limited, the self-contained storage battery can not be maintained for a long time, once the power failure time of the commercial power is long, if the mobile communication base station needs to keep working, a general generator is needed to be adopted to generate electricity to provide electric energy.
A common mobile communication base station is generally shared by a plurality of mobile operators who share a base station service by making a service agreement with a mobile communication base station operating company. The service agreement generally has a rule, and mobile communication base station operation company is under the commercial power outage condition, and the time of the free guarantee service is 3 hours, and in 3 hours, the base station utilizes the battery guarantee power supply. After more than 3 hours, mobile communication base station operating companies will provide paid services using general-purpose generators to generate electricity. Because of the existing mobile communication base station equipment structure shared by multiple mobile operators, the load equipment (including wireless equipment and transmission equipment) of each operator is intensively connected to the primary power-off and/or secondary power-off direct-current output terminal of the same switching power supply system, and power is taken from the same switching power supply system. As shown in fig. 3, the wireless devices of each operator are connected to the terminal block under the control of the first release of the switching power supply system, and the transmission devices of each operator are connected to the terminal block under the control of the second release. When the mains supply is powered off, the storage battery of the base station starts to discharge, when the voltage of the storage battery is reduced to about 47V, the first tripper is disconnected, and at the moment, all wireless equipment of each operator is powered off; when the voltage of the storage battery is lowered to about 43V, the second tripper is disconnected, the storage battery stops supplying power, and at the moment, all transmission equipment of each operator is powered off. However, each mobile operator has different requirements on whether to continue to provide power generation guarantee after the mains supply has been powered off for 3 hours, some mobile operators require to continue to supply power, and some mobile operators do not require to continue to supply power. If the battery capacity can not guarantee the power failure time length, the base station needs to be provided with a generator for generating power. However, in the existing shared equipment structure of the mobile communication base station, after the mains supply is powered off, it is impossible to provide power generation service or storage battery power supply service only for the operator equipment requiring continuous power supply as required, and only power generation service can be continuously provided or power failure occurs. And the service agreement of the base station service provider and the operator generally signs a disclaimer, namely the power of the commercial power is cut off at 0-6 points at night, and the base station service provider does not provide power generation service. In view of the fact that the existing shared mobile communication base station cannot provide differentiated services according to the requirements of operators, how to realize user-based management control on the load of the operators in the base station has been an unsolved problem for a long time.
