In the correlation technique, need subscriber equipment in real time multicarrier to be measured.In the embodiment of the invention, subscriber equipment has only judgement to satisfy the entry condition of measuring in the multicarrier, just starts this measurement, can avoid subscriber equipment to start measurement in real time, thereby avoid subscriber equipment significantly to increase power consumption, and improve user experience.
Preferably, UE usage threshold value judges that the signal quality of one or more Serving cells satisfies the entry condition of measuring in the multicarrier, and starting the base station is all measurements of UE configuration.
Need to prove, in this preferred embodiment, can both satisfy carrier management needs in the multicarrier system, be unlikely to again to start measurement too early, trigger a large amount of measurement reports, thereby reduced the power consumption of UE, give user's favorable experience.
Particularly, before starting above-mentioned all measurements, can judge the entry condition that satisfies to measure in the multicarrier by following three kinds of modes.
(1) threshold value is for characterizing first threshold value of Serving cell signal quality; Entry condition is that the signal quality of the main Serving cell in the Serving cell is lower than first threshold value, and perhaps the signal quality of the auxilliary Serving cell of any activation in the Serving cell is lower than first threshold value; Entry condition is satisfied in the UE judgement, and starting the base station is all measurements of its configuration.
(2) threshold value comprises first threshold value that characterizes main Serving cell signal quality and second threshold value that characterizes auxilliary Serving cell signal quality; Entry condition is that the signal quality of the main Serving cell in the Serving cell is lower than first threshold value, and perhaps the signal quality of the auxilliary Serving cell of any activation in the Serving cell is lower than second threshold value; Entry condition is satisfied in the UE judgement, and starting the base station is all measurements of its configuration.
