Abstract

Increased usage of maildrop services in the pag- ing industry has resulted in pagers having the abil- ity to identify, and store better quality maildrop mes- sages. One of the most typical maildrop storage schemes is just to store a new maildrop message irregardless of the new maildrop message quality, If a new maildrop message was a duplicate of the existing message and contains more errors, it will replace the older message which has a better mes- sage quality. This is highly undesirable as the user does not get a good representation of the maildrop message. In countries like Germany where ripple- transmitting paging systems are employed, the same maildrop message is sent repeatedly over a number of transmitters to ensure that area coverage is sufficiently large. This may result in the pager stor- ing the last maildrop message which may be ofworse quality than the previous maildrop message.

RETAIN BETTER DUPLICATE MAILDROP

by Ng Kam Pheng and Ong Dee Nai

  Increased usage of maildrop services in the pag- ing industry has resulted in pagers having the abil- ity to identify, and store better quality maildrop mes- sages. One of the most typical maildrop storage schemes is just to store a new maildrop message irregardless of the new maildrop message quality, If a new maildrop message was a duplicate of the existing message and contains more errors, it will replace the older message which has a better mes- sage quality. This is highly undesirable as the user does not get a good representation of the maildrop message. In countries like Germany where ripple- transmitting paging systems are employed, the same maildrop message is sent repeatedly over a number of transmitters to ensure that area coverage is sufficiently large. This may result in the pager stor- ing the last maildrop message which may be ofworse quality than the previous maildrop message.

  This new algorithm addresses the issue of iden- tifying a better quality maildrop message. This algorithm uses combinations ofinformation such as

ERRORED, BAD-TRUNCATED (message term- inated abnormally), DUPLICATE-SO-FAR (shorter message is duplicate of the longer message for the length of the shorter message), RETAIN-BETTER- MESSAGE (retain message which contains more good or un-errored characters) and MESSAGE-LENGTH
to decide which message to store.

  By using the algorithm shown in the flowchart, the pager arrives at two choices, to discar...
