Method and apparatus optimizing receipt of call/broadcast paging messages by self-powered wireless communications devices

摘要

A wireless communications network ( 120 ) responds to each incoming call placed to a wireless communications device ( 134 ) by transmitting a call-paging message ( 418 ) within a corresponding partition of a digital radio frame of prescribed format. Responsive to each occurrence of a broadcast event ( 404 ), the network transmits ( 414 ) a repeating broadcast-paging message announcing the availability of broadcast content from the network. The broadcast-paging message is transmitted multiple times within each digital radio frame. Another sequence ( 500 ) describes WCD operation in this network. Responsive to wakeup ( 502 ) from sleep, the WCD detects ( 509 ) received signal quality. The WCD also receives ( 510 ) scheduled network transmission of a call-paging message and a number of instances (at least one) of a repeating network transmitted broadcast-paging message that occurs multiple times for each scheduled transmission of the call-paging message. This number varies inversely with the detected signal quality.
