Abstract
A method for power management in handover between heterogeneous networks comprising: an MIH layer obtains power information and provides it for an MIH user layer; the MIH user layer determines the handover policy according to the power information. In various embodiments of the disclosure, the MIH layer triggers an event so that the MIH user layer can obtain power information, and select a lower-layer network connection automatically according to the current power status, thus implementing handover; the MIH user layer sends a query request to the MIH layer to obtain power consumption parameters from the network, and selects a lower-layer network connection according to the power consumption and the current power status, thus implementing handover and making more accurate and effective decisions in the handover.
