MULTI-MODE TRAFFIC ENGINEERED HANDOVER MANAGEMENT DEVICE AND METHOD FOR A BROADBAND WIRELESS ACCESS NETWORK

摘要

A handover management device (D1) is intended for a broadband wireless access network (AN) comprising a plurality of base stations (BS1-BS6) to which communication equipments (CE1-CE7) may be connected to. This device (D1) is arranged, when it receives, from either a base station (BSl) or a communication equipment (CE2) connected to this base station (BSi), an alarm message signalling either i) a degradation of at least one decision metric, representative either of the quality of a signal transmitted between this connected communication equipment (CE2) and this base station (BS1) or of a quality of service offered by this base station (BS1) to this connected communication equipment (CE2), or ii) an overload of this base station (BS1), for triggering a handover assisted either by this connected communication equipment (CE2) and possibly this base station (BS1) and involving a target base station (BS2) to be selected, or by a selected target communication equipment (CE5) and this base station (BS1) and involving a target base station (BS2) to be selected.
