Abstract
A method for handover between base stations of an access system for access to a core network including interconnections in a tree structure having wireless links and a single wired link. The wired link connects only one of the base stations, known as a donor node, to the core network. The interconnections between the base stations are solely wireless links. The method includes: transmitting, by a source base station of the access system, to which a terminal is attached, a handover request to a target base station of the access system, the source and target base stations being interconnected via at least one base station known as a decision-making node, which is different from the donor node; intercepting the handover request by the decision-making node; transmitting, by the decision-making node, an agreement message to the source base station; and transmitting a handover trigger message to the target base station.
