초록 ▼

A cellular phone paging system that uses a frame oriented scheme to transmit and receive mobile unit pages with reduced delay is disclosed. Each mobile unit in the cellular phone network is assigned a paging slot within the frames on the forward control channel. If a plurality of pages are to be sent along the forward control channel and the pages are assigned to the same paging slot, the pages will be transmitted in successive paging slots beginning with the assigned slot rather than in the assigned slot in a series of sequential frames. In order to receive its pages, a mobile unit inspects its assigned paging slot and the next sequential paging slots if its assigned paging slot has been filled with a page request to another unit. The mobile unit continues to check sequential paging slots until it identifies a page to itself or identifies an empty slot. The mobile unit may reduce its power consumption by turning off some of its electronic circuitry while not monitoring the contents of its assigned slot and, if necessary, the contents of successive slots. In this manner, paging delays between base stations and mobile units are reduced to a minimum while maintaining idle mode power consumption conservation provided by frame-based paging schemes.

대표청구항 ▼

For use in a wireless telephone network including a call processing system operative to communicate with mobile units on a forward control channel by transmitting control signals in a series of concatenated frames having a plurality of paging slots, each of said paging slots having a corresponding plurality of mobile units assigned thereto, an improved system for transmitting a page to a mobile unit, comprising: a Mobile Telephone Switching Office (MTSO); at least one base station in electrical communication with said MTSO and said plurality of mobile units; at least one controller in electrical communication with said MTSO and said base station, said controller operative to: (a) determine the assigned paging slot for the mobile unit; (b) determine if the slot is available in its next occurrence in a frame; (c) sequentially check each successive paging slot in the frame for availability if the assigned slot is not available; and (d) place the page in a first available paging slot; and a transmitter for transmitting the frame of said placed page on the forward control channel.
