METHOD AND APPARATUS FOR REDUCING PAGING-RELATED DELAYS

In general, paging-related delays are reduced by empowering an idle mobile ( 120 ) to initiate a transition to semi-dormant, unslotted mode, and/or RSCI modes, based on triggers ( 304 ) known to the MS. This is an efficient manner (in terms of both RF and battery-life cost considerations) in which t...

Zusammenfassung:	In general, paging-related delays are reduced by empowering an idle mobile ( 120 ) to initiate a transition to semi-dormant, unslotted mode, and/or RSCI modes, based on triggers ( 304 ) known to the MS. This is an efficient manner (in terms of both RF and battery-life cost considerations) in which to use semi-dormant and RSCI modes ( 306 ). If the MS ( 120 ) is able to anticipate a paging channel (PCH) message (for example, after sending or receiving an SMS or presence update), then the MS can intelligently reduce its slot cycle index for a short period of time, sacrificing a small amount of battery life, when the R-SCI is most likely to deliver improved service. Moreover, if the MS is low mobility (i.e. low idle handoff rate), then the MS can transition to a semi-dormant mode with very little cost, since it will not need to send many radio environment reports.
