Abstract: A cellular telephone concentrated subscriber system is described. The concentrated subscriber system includes a set of subscriber units each having a unique electronic serial number that are coupled to a concentrated subscriber system controller that provides an radio frequency (RF) interface to the standard base station transceiver of a cellular telephone system. The concentrated subscriber system controller includes a set of modulator-demodulator systems (modems) and a RF transceiver and antenna system that is configured to transmit sufficient information to conduct multiple telephone calls over both long and short distances. The concentrated subscriber system controller also includes control circuitry for coupling the set of subscriber unit to the set of modems via a multiplexed system using stored information. In the preferred embodiment the number of modems is significantly less the number of subscriber units which are implemented in a simplified manner so that the per user cost of cellular telephone service is reduced.

Title: On-line mining of quantitative association rules
Inventor: AGGARWAL CHARU CHANDRA
IPC: G06F17/30
Filed: 1998-07-29
Granted: 2002-10-11
Abstract: A computer method of online mining of quantitative association rules consisting of two stages, a preprocessing stage followed by an online rule generation stage. The required computational effort is reduced by the pre-processing stage, defined by pre-processing data to organize the relationship between antecedent attributes to create a heirarchially arranged multidimensional indexing structure. The resulting structure facilitates the performance of the second stage, online processing, which involves the generation of quantitative association rules. The second stage, online rule generation, utilizes the multidimensional index structure created by the preprocessing stage by first finding the areas in the data which correspond to the rules and then uses a merging step to create a merged tree in order to carefully combine interesting regions in order to give a heirarchical representation of the rule set. The merged tree is then used in order to actually generate the rules.
