Method, device and system for reducing power consumption of mobile terminal

A method for reducing power consumption of a mobile terminal, the method being applied to an access network device, the method comprising:

• receiving a parameter adjustment request sent by a mobile terminal connected to the access network device, wherein the parameter adjustment request includes battery level information of the mobile terminal;
• generating a parameter adjustment instruction based on the parameter adjustment request, wherein the parameter adjustment instruction includes a communication parameter to be adjusted, and the communication parameter to be adjusted is a baseband-chip related communication parameter,
• wherein generating the parameter adjustment instruction based on the parameter adjustment includes:
• determining, based on the battery level information, the communication parameter to be adjusted from baseband-chip related communication parameters in the mobile terminal, wherein a number of the baseband-chip related communication parameters to be adjusted is inversely proportional to a battery level indicated by the battery level information;
• and
• generating the parameter adjustment instruction based on the communication parameter to be adjusted, and
• wherein generating the parameter adjustment instruction based on the parameter adjustment further includes:
• when a battery level indicated by the battery level information is less than a third power threshold, determining an adjustment frequency band, wherein the adjustment frequency band allows a communication quality higher than that of the current communication frequency band of the mobile terminal;
• and
• generating the parameter adjustment instruction based on the adjustment frequency band, wherein the parameter adjustment instruction also instructs the mobile terminal to adjust the communication frequency band to the adjustment frequency band;
• and
• sending the parameter adjustment instruction to the mobile terminal, wherein the parameter adjustment instruction instructs the mobile terminal to adjust the baseband-chip related communication parameter in the mobile terminal to reduce the power consumption of the mobile terminal.

A mobile terminal, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor,
• wherein the processor is configured to:
• send a parameter adjustment request to an access network device connected to the mobile terminal in response to an instruction for reducing power consumption, wherein the parameter adjustment request includes battery level information of the mobile terminal;
• receive a parameter adjustment instruction sent by the access network device, wherein the parameter adjustment instruction includes a communication parameter to be adjusted, and the communication parameter to be adjusted is a baseband-chip related communication parameter,
• wherein the parameter adjustment instruction is generated at the access network device based on the parameter adjustment request by:
• determining, based on the battery level information, the communication parameter to be adjusted from baseband-chip related communication parameters in the mobile terminal, wherein a number of the baseband-chip related communication parameters to be adjusted is inversely proportional to a battery level indicated by the battery level information;
• and
• generating the parameter adjustment instruction based on the communication parameter to be adjusted, and
• wherein the parameter adjustment instruction is generated at the access network device based on the parameter adjustment request further by:
• when a battery level indicated by the battery level information is less than a third power threshold, determining an adjustment frequency band, wherein the adjustment frequency band allows a communication quality higher than that of the current communication frequency band of the mobile terminal;
• and
• generating the parameter adjustment instruction based on the adjustment frequency band, wherein the parameter adjustment instruction also instructs the mobile terminal to adjust the communication frequency band to the adjustment frequency band;
• and
• adjust the baseband-chip related communication parameter in the mobile terminal based on the parameter adjustment instruction to reduce the power consumption of the mobile terminal.
