Patent ID: 7929490

Claim:
A paging method in a wireless communication system, wherein a wireless communication device (WCD) listens in a sequence of time slots for paging messages, wherein sequential time slots of the sequence are separated from one another by a first time interval, and in which a radio access network (RAN) normally (1) transmits, in a time slot of the sequence, a paging message of a series of paging messages to the WCD, (2) waits a second time interval, (3) transmits a next paging message of the series in a next time slot of the sequence, and (4) discontinues the series upon receipt of a paging response from the WCD, the method comprising: after transmitting a given paging message of the series, the RAN detecting that the WCD has changed from operating on a first carrier frequency to operating on a second carrier frequency; and responsive to the detecting, the RAN transmitting a subsequent paging message to the WCD on the second carrier frequency in the next time slot of the sequence without waiting for expiration of the second time interval; wherein transmitting the subsequent paging message to the WCD on the second carrier frequency comprises restarting the series and thus transmitting a starting paging message of the series on the second carrier frequency.
