System and method for including origination time and update lifetime with updateable messages
First Claim
1. In a selective call communication system for providing updateable messages and message updates to one or more messages for one or more message receiver/decoders, a method comprising the steps of:
- encoding messages and updates to messages, the step of encoding encodes a message with an origination time, a version number and an update lifetime indicator and a message update with the origination time and the version number;
transmitting the message and the message update to one or more message receivers, in a message receiver, the method comprises the steps of;
receiving the message and the message update;
processing the message to determine when the message update is being received;
checking the update lifetime indicator of the message to determine if the message to which the message update is intended can be updated; and
comparing the origination time of the message with the origination time of the message update to determine when the message update is an out-of-sequence message update.

Abstract
An updateable message encoder/transmitter (100) has a processor (109) for encoding messages and message updates. A message includes an origination time (191), a version number (410) and an update lifetime indicator (424), and a message update includes the origination time (191) and the version number. A transmitter (120) broadcasts the message and the message update message receiver/decoder (130) receives the message and the message update, a processor (212) processes the message to determine when the message update is being received. The processor checks the update lifetime indicator of the message indicated by the message update to determine if the message to which the message update is intended can be updated. A comparator compares the origination time of the message with the origination time of the message update to determine if the message update is an out-of-sequence message update.

12. An updateable message encoder/transmitter, comprising:
-
a processor for encoding messages and updates to messages forming message updates, a message includes an origination time, a version number and an update lifetime indicator, and a message update includes the origination time and the version number; a transmitter for broadcasting the message and the message update to a message receiver/decoder, the message receiver/decoder, comprising; a receiver for receiving the message and the message update; a processor for processing the message to determine when the message update is being received, the processor checks the update lifetime indicator of the message indicated by the message update to determine if the message to which the message update is intended can be updated; and a comparator for comparing the origination time of the message with the origination time of the message update to determine if the message update is an out-of-sequence message update. - View Dependent Claims (13, 14)
