Abstract

A wireless device operates under network control. The wireless device operates using a first radio access technology under control of a network control apparatus 204. The wireless device determines that using a different radio access technology would consume less power 210. The wireless device signals to the network control apparatus that it would like to use the different radio access technology in order to achieve power savings 220 (e.g. by sending a SIGNALLING CONNECTION RELEASE INDICATION (SCRI) message). When the network receives a request to use a different radio access technology in order to achieve power savings at the wireless device, the network transmits a signal that at least one of: (i) redirects the wireless device to the different radio access technology in response to receipt by the network control apparatus of the signalling from the wireless device; (ii) changes cell reselection priorities of the wireless device such that the different radio access technology has a higher priority; and (iii) hands over the wireless device to a cell that uses the different radio access technology. The wireless device may monitor power consumption over time for different applications running on the device or for different activity states of the device.
