Title (EN) MOBILE COMMUNICATION METHOD
(FR) PROCÉDÉ DE COMMUNICATION MOBILE
(JA) 移動通信方法
Abstract: front page image
(EN)A mobile communication method includes a step in which a handover-originating wireless base station transmits a handover request including NCC, PCI, and KeNB* to a switching station; a step in which the switching station changes NCC and changes KeNB* based on PCI, and transmits a handover request including the changed NCC and the changed KeNB* to a handover-destination wireless base station; a step in which the handover-destination wireless base station generates a first key based on KeNB*; and a step in which a mobile station generates the first key based on the NCC and PCI included in the handover command.
(FR)L'invention concerne un procédé de communication mobile comprenant une étape au cours de laquelle une station de base sans fil produisant un transfert intercellulaire transmet une demande de transfert intercellulaire comprenant NCC, PCI, et KeNB* à une station de commutation; une étape au cours de laquelle la station de commutation modifie NCC et modifie KeNB* sur la base de PCI puis transmet une demande de transfert intercellulaire comprenant le NCC modifié et le KeNB* modifié à une station de base sans fil destinataire du transfert intercellulaire; une étape au cours de laquelle la station de base sans fil destinataire du transfert intercellulaire génère une première clé sur la base de KeNB*; et une étape au cours de laquelle une station mobile génère la première clé sur la base de NCC et PCI contenus dans la commande de transfert intercellulaire.
(JA)本発明に係る移動通信方法は、ハンドオーバ元無線基地局が、交換局に対して、NCCとPCIとKeNB*とを含むハンドオーバ要求を送信する工程と、交換局が、NCCを変更すると共に、PCIに基づいてKeNB*を変更し、ハンドオーバ先無線基地局に対して、変更されたNCCと変更されたKeNB*とを含むハンドオーバ要求を送信する工程と、ハンドオーバ先無線基地局が、KeNB*に基づいて第1鍵を生成する工程と、移動局が、ハンドオーバ指示に含まれているNCCとPCIとに基づいて第1鍵を生成する工程とを有する。
