Title (EN) COMMUNICATION SYSTEM, COMMUNICATION TERMINAL DEVICE, AND HANDOVER METHOD
(FR) SYSTEME DE COMMUNICATION, TERMINAL DE COMMUNICATION ET PROCEDE DE TRANSFERT
(JA) 通信システム、通信端末装置及びハンドオーバ方法
Abstract: front page image
(EN)A communication system, a communication terminal device, and a handover method that allow the communication terminal device to smoothly perform handover among networks in a communication system where networks of different types, such as a wireless LAN and a cellular system, exist. Relay means in the communication terminal device sends information about the communication terminal device used in one network to another network.
(FR)Système de communication, terminal de communication et procédé de transfert permettant au terminal de communication d'effectuer facilement un transfert entre des réseaux dans un système de communication où existent différents types de réseaux tels qu'un réseau LAN radio et un système cellulaire. Un relais dans le terminal de communication envoie vers un autre réseau des informations sur le terminal de communication utilisé dans un réseau.
(JA)無線LANや携帯電話システム等の異種ネットワークが混在する通信システムにおいて、通信端末装置が前記ネットワーク間でハンドオーバを円滑に行えるようにする通信システム、通信端末装置及びハンドオーバ方法を提供する。通信端末装置に具備される中継手段は、一のネットワークで使用されたその通信端末装置についての情報を他のネットワークに通知する。
