Patent ID: 7626956

Claim:
A method for synchronizing measurement events within a portable radio communication apparatus providing multiple radio access technologies including a first radio access technology device and a second radio access technology device, comprising the steps of: the portable radio communication apparatus engaging in transceiver activities that are separated by one or more idle gaps; the portable radio communication apparatus ascertaining whether an idle gap between transceiver activities of the first radio access technology device is suitable for usage by the second radio access technology device; the first radio access technology device responding to the idle gap between transceiver activities of the first radio access technology device being suitable for usage by the second radio access technology device by sending an execute signal to the second radio access technology device for initiating inter radio access technology measurements of said second radio access technology device to be performed during said idle gap; the second radio access technology device responding to the execute signal by performing a measurement operation during the idle gap; and preparing said second radio access technology device for performing said inter radio access technology measurements, wherein said step of preparing said second radio access technology device comprises the step of: determining whether inter radio access technology measurements are possible during a next gap, based on information about an estimated length of said gap.
