SYSTEM AND METHOD OF POWER MANAGEMENT FOR A DEVICE WITH MULTIPLE NETWORK INTERFACES

摘要

Provided are a method for managing power of a user device having a plurality of interfaces, a method for operating a user device comprising a first wireless interface configured to communicate with a first wireless network and a second wireless interface configured to communicate with a second wireless network, a method for operating a wireless base station configured to transmit to user devices on a first network, and a wireless communications system. The method for managing power of a user device having a plurality of interfaces comprises: mapping centralized reachability states to physical power states of the interface; and controlling the physical power states based on the mapping, wherein the controlling comprises transmitting a signal to the user device.
