Abstract
Abstract A pager system in which individual pagers have a database is disclosed. The database can be updated by transmitting a mask code and update data. The mask code indicates a mask stored in the individual pager itself which receives the data. Using the mask code, the mask is identified and used to indicate positions in the database where data is to be written.

Claim 1
Independent Claim
71 words
A method for disseminating modifications to a database stored in a plurality of receivers, comprising the steps of: transmitting a mask code and mask data; storing in said receivers a mask indicating positions in said database where said mask data is to be written; examining a received message to detect said mask code; and writing, in response to said mask code, said mask data at said positions indicated by said mask.
Claim 2
Independent Claim
71 words
A method for disseminating modifications to a database stored in a plurality of receivers, comprising the steps of: transmitting a mask code and mask data; storing in said receivers a mask indicating positions in said database where said mask data is to be written; examining a received message to detect said mask code; and writing, in response to said mask code, said mask data at said positions indicated by said mask.
Claim 3
Dependent Claim
25 words
The method of claim 1 further comprising the steps of: transmitting said mask to said receivers; and receiving and storing, in said receivers, said mask.
Claim 4
Dependent Claim
80 words
The method of claim 1 further comprising the steps of: storing a plurality of masks in said receivers, each mask having a corresponding mask ID; transmitting a mask ID with said mask data; comparing a received mask ID with the mask IDs stored in said receiver; and if said received mask ID matches a stored mask ID, retrieving a mask corresponding to said mask ID and writing said mask data at said positions in said database indicated by said mask.
Claim 5
Independent Claim
122 words
A method for disseminating modifications to a database stored in a plurality of receivers, comprising the steps of: transmitting a mask code, mask ID and mask data; storing in said receivers a plurality of masks and mask IDs, each mask ID corresponding to a different one of said masks, each mask indicating positions in said database where said mask data is to be written; examining a received message for said mask code; comparing, in response to detecting aid mask code, a received mask ID to said stored mask IDs; if said received mask ID matches a stored mask ID, retrieving a mask corresponding to said mask ID; and writing aid mask data at positions in said database indicated by said retrieved mask.
Claim 6
Independent Claim
122 words
A method for disseminating modifications to a database stored in a plurality of receivers, comprising the steps of: transmitting a mask code, mask ID and mask data; storing in said receivers a plurality of masks and mask IDs, each mask ID corresponding to a different one of said masks, each mask indicating positions in said database where said mask data is to be written; examining a received message for said mask code; comparing, in response to detecting aid mask code, a received mask ID to said stored mask IDs; if said received mask ID matches a stored mask ID, retrieving a mask corresponding to said mask ID; and writing aid mask data at positions in said database indicated by said retrieved mask.
Claim 7
Dependent Claim
33 words
The method of claim 4 further comprising the steps of: transmitting at least one of said masks and mask ID; and receiving and storing in said receivers said transmitted mask and mask ID.
Claim 8
Dependent Claim
52 words
The method of claim 4 further comprising the steps of: transmitting an indication of a number of blocks of data, for said retrieved mask; and repeatedly using said retrieved mask in said receivers to write different portions of said mask data on different pages of said database as indicated by said indication.
Claim 9
Dependent Claim
44 words
The method of claim 6 further comprising the steps of: transmitting a number of pages to be skipped after each use of said retrieved mask; and skipping, in said receivers, said number of pages after each write of mask data using said retrieved mask.
