Method and apparatus for transmitting information in power communications system, and system

A method for transmitting information in a power communications system, wherein the method is applied to a power communications system that uses at least two frequency bands for wireless communication, frequency band licensing statuses of the at least two frequency bands are different, and the method comprises:

• determining a target frequency band from the at least two frequency bands based on an emergency degree of information to be sent and a correspondence between the emergency degree and each of the at least two frequency bands;
• and
• sending the to-be-sent information using the target frequency band.

An apparatus for transmitting information in a power communications system, wherein the apparatus is applied to a power communications system that uses at least two frequency bands for wireless communication, frequency band licensing statuses of the at least two frequency bands are different, and the apparatus comprises:

• a determining module configured to determine a target frequency band from the at least two frequency bands based on an information type of information to be sent and a correspondence between the information type and each of the at least two frequency bands;
• and
• a sending module configured to send the to-be-sent information using the target frequency band determined by the determining module.
