FIELD: physics, communications.
SUBSTANCE: invention relates to communication engineering. The method is realised between an access terminal (AT) and an access networks (AN) in a wireless communication system. The method involves sending (S41) a notification message to the AN, reception (S42) of a confirmation message from the AN and switching (S43) into power saving mode in accordance with a certain power saving mode. The notification message includes information on the life of the accumulator and a request for the power saving mode, and the confirmation message includes a certain power saving mode which is based on information on the life of the accumulator and the request for the power saving mode.
EFFECT: saving accumulator power.
