Abstract

See full text

The method for transfer between systems of different generation includes: modeling with cutting-out of the network into radio cells by distinguishing the frequency bands used, hierachization using coverage data for producing in tables (T) for each frequency band, best/second best server cell data, respectively, representative of an index listing zones corresponding to the best/second best coverage level, determining the zone of radio cells and the source frequency band used in a first system by the terminal, followed by selecting a corresponding starting cell (21, 22) in the tables, generating from the tables a list of candidate cells belonging to a second system and neighbors of the starting cell, selecting in the list at least one arrival cell according to selection criteria.
