METHOD AND SYSTEM FOR CALCULATING THE 2G-3G NEIGHBORHOOD FOR AUTOMATIC CONNECTION TRANSFER BETWEEN 2G AND 3G SYSTEMS

摘要

The method of transfer between systems of different generation comprises: - a modeling with division of the network into radio cells by distinguishing the frequency bands used, - a hierarchy using coverage data to produce in tables (T), for each band of frequencies, data of best / best second server cell respectively representative of an index listing areas corresponding to the best / best second level of coverage, - a determination of the area of radio cells and the frequency band "source" used in a first system by the terminal, followed by a selection in the tables of a corresponding start cell (21, 22), - a generation from the tables of a list of candidate cells belonging to a second system and adjacent to the starting cell, - a selection in said list of at least one arrival cell according to criteria of s election.
