  • Patent number: 8059604
    Abstract: A signal measurement method for a mobile communication apparatus supporting multiple transmission interfaces to perform communication transmission in a heterogeneous network environment, system and a recording medium thereof. Changes in the signal strength of an active network transmission interface are employed to adjust signal measurement periods of other non-active network transmission interfaces, thereby reducing the signal measurement frequency of these non-active network transmission interfaces. Moreover, as for the situation that a specific transmission interface periodically reports the signal measurement result to a remote network server, the signal measurement time during the report can also be reduced. By solving the power consumption problem caused by frequently activating the signal measurement of the mobile communication apparatus, the efficacies of saving power and improving the standby time and talk time can be achieved.
