Abstract
A method and apparatus for detecting a periodic message in a mobile communication system includes initiating, at a receiver, a reception of synchronization data a predetermined amount of time prior to a current periodic message. The predetermined amount of time is based on at least one of an estimated signal quality value from at least one prior periodic message and an estimated error in the at least one prior periodic message. The synchronization data is used to achieve synchronization, and the current periodic message is detected based on the synchronization.
Claims24
A method for reducing time of reception during paging in a communication system, comprising the steps of:
- receiving at least one paging-related message prior to receiving a current paging-related message;
- determining an estimated signal quality value based on said at least one paging-related message;
- determining a time period for receiving synchronization data based on said estimated signal quality value;
- activating said receiver during said time period to receive a signal containing said synchronization data;
- and
- synchronizing said receiver with the received signal based on said synchronization data.
An apparatus for reducing time of reception during paging in a communication system, the apparatus comprising:
- a receiver for receiving a plurality of paging-related messages;
- a device for determining an estimated signal quality value from at least one of said plurality of paging messages received prior to receiving a current paging message;
- and
- a controller for determining a time period for receiving synchronization data based on said estimated signal quality value and for activating said receiver during said time period to receive said synchronization data.
A method for detecting a periodic message in a mobile communication system, comprising the steps of:
- initiating a reception of synchronization data a predetermined amount of time prior to a current periodic message, said predetermined amount of time based on at least one of an estimated signal-to-noise ratio (SNR) from at least one prior periodic message, an estimated error in said at least one prior periodic message, and an estimated radio path profile from at least one prior periodic message;
- using said synchronization data to achieve synchronization;
- and
- detecting said current periodic message based on said synchronization.
