Abstract

See full text

A mobile handset capable of operation on more than one wireless system has means for periodically testing for the availability of at least one system whilst operatively connected to another system, wherein the periodicity of the testing process is made at one rate when a call is in progress and at a second rate when no call is in progress (on standby). This significantly reduces power consumption when on standby, without impairing handover reliability if a call is in progress.
