The invention provides a power control method and power control equipment for radio access network equipment. The method comprises the following steps that: a base band unit controls a radio frequency unit to establish connection with a base station according to first transmission power no more than prestored power, wherein the first transmission power is the maximal default transmission power for power supply; a radio frequency unit acquires second transmission power which is needed for establishing communication connection with the base station from the base station; if the second transmission power is more than the first transmission power, the base band unit and a terminal connected with the radio access network equipment negotiate to regulate the power supply information for the radio access network equipment so as to ensure that the radio access network equipment can work according to the second transmission power; and the base band unit controls the radio frequency unit to establish connection with the base station according to the second transmission power so as to initial services normally. The technical scheme of the embodiment of the invention can effectively improve the control efficiency of the maximal transmission power of the radio access network equipment so as to improve the working performance of the radio access network equipment.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a power control method and device for a wireless access network device. Background technique [0002] With the rapid development of wireless communications, wireless access network devices such as wireless data cards are used more and more widely. [0003] In the prior art, a wireless access network device obtains power from a terminal connected to it through a port for its normal operation. Usually, the corresponding maximum transmit power is stored in a non-volatile memory in the wireless access network device. In order to ensure that the power consumption of the wireless access network equipment does not exceed the power supply capacity of the terminal connected to it, the method of limiting the maximum transmission power is adopted. The wireless access network equipment can only use the transmission power not greater than the maximum trans...
