Patent ID: 8543129

Claim:
A method of managing communication in a cellular telecommunication network capable of using multiple carrier frequencies including a primary carrier frequency and at least one secondary carrier frequency, wherein the method comprises: determining a downlink quality measurement of a primary carrier frequency for a first set of one or more cells; determining a downlink quality measurement of at least one secondary carrier frequency for the first set of cells; determining a downlink quality measurement of the primary carrier frequency for a second set of one or more cells; determining a downlink quality measurement of the at least one secondary carrier frequency for the second set of cells; combining the downlink quality measurement of the primary carrier frequency and the downlink quality measurement of the at least one secondary carrier frequency to generate a combined quality measure based on the downlink quality measurement of the primary carrier frequency for the first set of cells, the downlink quality measurement of the at least one secondary carrier frequency for the first set of cells, the downlink quality measurement of the primary carrier frequency for the second set of cells and the downlink quality measurement of the at least one secondary carrier frequency for the second set of cells; determining whether the combined quality measure fulfills a predetermined condition; and in response to determining that the combined quality measure fulfills the predetermined condition, triggering an event.
