First Claim
Patent Images
1. In a mobile communications network, a method of identifying messages transmitted in said mobile communications network for storage in a memory and for clearing said messages comprising the steps of:
- creating a header for each message stored in said memory, said header containing required identifiers;
setting a lifetime for each of said stored messages in said header, said lifetime being a period in which the stored message can be actuated;
measuring a period of time from expiration of said lifetime to a transmission of a new message;
when there is insufficient memory available for storing a new message, selecting one or more of said stored messages with a longest period of time from expiration of said lifetime, clearing said selected one or more of said stored messages and replacing said one or more of said stored messages with said new message, and signaling back the identifier of each of said one or more of said stored messages replaced with said new message; and
storing a last transmission in said mobile communications network, so that messages which are lost only have to be resent selectively.
