US Patent 7929490 Method and system for paging mobile devices

Methods and systems for improving the paging of wireless communication devices (WCDs) are introduced. A radio access network (RAN) begins transmitting a series of paging messages to a WCD, and determines that the WCD is operating on a new carrier frequency. The RAN proactively continues the series of paging messages on the new carrier frequency, without waiting for the prescribed interval between paging messages to expire. Alternatively, the RAN proactively restarts the series of paging messages on the new carrier frequency, without waiting for the prescribed interval between paging messages to expire. Both of these embodiments serve to reduce the delay involved in paging WCDs. The RAN may condition its behavior based on the WCD's profile.
