METHOD OF TIME AND FREQUENCY SYNCHRONIZATION OF MULTIMODE TERMINAL

摘要

A method of time-synchronizing at least two radio access modules of a multimode communication terminal capable to function according to at least two distinct radio access techniques in a cellular telecommunication network in which one of the radio access modules is active in the current cell and the other radio access module is in a passive state in the current cell comprises the steps of: (a) measuring for each of the cells adjacent to the current cell a time offset T<offset#191 between the start of a specific frame of the first radio technique and the start of a specific frame of the second radio access technique, and (b) using the time offset T?offset#191 measured in step (a) for synchronizing the passive radio access module with the active radio access modules.
