Method and apparatus for power management in handover between heterogeneous networks
First Claim
1. A method for power management in handover between heterogeneous networks, comprising:
- determining, by an media independent handover (MIH) user layer, a handover policy according to power information;
wherein the power information is obtained by an MIH layer; and
registering, by the MIH user layer, with the MIH layer a power event carrying a power threshold of a device;
wherein the information carried in the power event comprises;
source that triggers the event, media access control (MAC) address of the mobile device, predicted time interval from triggering a power event to complete power failure of the device, predicted probability of power failure of the device in the specified time interval;
current power, and information about the network interfaces incompliant with the current power requirement.

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.
