ABSTRACT:
Methods and apparatus for detecting and predicting movement patterns of mobile radio transceivers, such as mobile cellular telephones, enhance the performance of hierarchical radio networks, in which network structures, such as different cells, have different communication bandwidths. One method of predicting a next location of a mobile terminal based on stored previous locations of the mobile terminal includes the step of comparing a current sequence that includes the current location of the mobile terminal and a plurality of previous locations of the mobile terminal to each of a plurality of stored sequences that each include previous locations of the mobile terminal. The method also includes the steps of selecting one of the stored sequences based on at least one quantitative measure of a degree of matching between the current sequence and each stored sequence, and predicting the next location of the mobile terminal based on the selected one of the stored sequences. Methods and apparatus for determining regular patterns in movements of a mobile terminal are also described, as is a communication network having a plurality of servers, the servers being positioned in respective geographical areas and organized in a distributed file system; a mobile terminal having a device for communicating with the server nearest the mobile terminal, the communicating device accessing application files and data files stored in the servers; and a mobile distributed system platform having a device for controlling the distributed file system of the servers and a device for predicting a next location of a mobile terminal, the controlling device distributing location sensitive information among the servers based on a next location predicted by the predicting device.
