Abstract
A power management system is described where the handset can enter sleep or hibernation mode for a particular service, when the particular service is either not used or not available. The handset is capable of using the service, even in response to a non-user initiated incoming request for communication. The handset receives the request over the active service. The handset can then check for the availability of the inactive service, activate it, and a selection can be made between them.
