A communications network which is capable of effectively and efficiently handling mobility of wireless user terminals (118) between access point nodes (104, 106, 108) of a packet-switched network with minimal overhead and packet loss, and a method for using the same. The communications network employs a packet-switched core network (102) and a plurality of access points (104, 106, 108) coupled to the core network. Each access point (104, 106, 108) is adapted to provide any user terminal (118) with wireless communications access to the core network (102) when that user terminal becomes affiliated with that access point. The system and method further employ ad-hoc routing techniques during handoff of a wireless user terminal between access point nodes of the core network to enable the network to maintain multiple paths via which data packets are provided to the user terminal during handoff to substantially eliminate packet loss during handoff.

L'invention concerne un réseau de communications permettant de gérer de manière efficace et efficiente la mobilité de terminaux d'utilisateur sans fil (118) entre des noeuds de points d'accès (104, 106, 108) d'un réseau à commutation par paquet à surcharge système et perte de paquets minimales, et un procédé d'utilisation correspondant. Le réseau de communications utilise un réseau central à commutation par paquets (102) et plusieurs points d'accès (104, 106, 108) couplés au réseau central. Chaque point d'accès (104, 106, 108) est conçu de manière à fournir à chaque terminal d'utilisateur (118) avec un accès au réseau central (102) via des communications sans fil lorsque le terminal d'utilisateur s'affilie au point d'accès. Le système et le procédé utilisent, en outre, des techniques d'acheminement ad hoc durant le transfert intercellulaire d'un terminal d'utilisateur sans fil entre des noeuds de point d'accès du réseau central afin de permettre au réseau de mettre à jour les trajets multiples par le biais desquels les paquets de données sont transmis au terminal d'utilisateur durant le transfert intercellulaire en vue de sensiblement éliminer les pertes de paquets durant le transfert.
