METHOD AND EQUIPMENT FOR MANAGING THE CONNECTION OF A TERMINAL IN WIRELESS COMMUNICATION NETWORKS
First Claim
1. Method for managing within a global heterogeneous network the transition of a terminal (1) connected to a first wireless communication network (3) having a first coverage zone towards a second wireless communication network (5) having a second coverage zone overlapping at least partially said first coverage zone wherein said method comprises the following steps:
- determining the terminal (1) location;
determining the networks topology of the surroundings of said terminal (1);
if the terminal (1) is in a predetermined area corresponding to the coverage border of said first wireless communication network (3),determining the optimal instant for triggering a pre-attachment process or a scanning of the surroundings of said terminal (1),determining available candidate networks (5) of the surroundings of said terminal (1),selecting, among said available candidate networks and based on at least one predetermined criterion, said second wireless communication network (5) and,requesting to the first wireless communication network (3) a pre-attachment or a handover to said selected second wireless communication network (5).
