Title (EN) ACCESS NETWORK TRANSFER METHOD FOR A ROAMING MOBILE TERMINAL
(FR) PROCÉDÉ DE TRANSFERT DE RÉSEAU D'ACCÈS POUR UN TERMINAL MOBILE EN ITINÉRANCE
Abstract:
(EN) The invention relates to an access network transfer method for a mobile terminal, termed the first terminal (UE A), belonging to an IP (Internet Protocol) network, comprising the following steps: detecting that it becomes necessary for said first terminal (UE A) to move from a first to a second access network of said IP network; and an ATCF (Access Transfer Control Function) server controlling said first terminal (UE A) forwards, to an SCC-AS (Service Centralisation and Continuity) application server, via an IBCF (Interconnection Border Control Function) server, a query suitable for informing said SCC-AS application server that a network access transfer procedure has been initiated for the first terminal (UE A). According to the invention, said query is configured to indicate to said SCC-AS application server that it should not propagate this query to a client device, termed the second terminal (UE B), also belonging to the IP network, with which the first terminal is in the course of communicating. The invention is of use in IMS networks.
(FR) L'invention concerne un procédé de transfert de réseau d'accès pour un terminal mobile, dit premier terminal (UE A), appartenant à un réseau IP (Internet Protocol), comprenant les étapes suivantes : détection qu'il devient nécessaire pour ledit premier terminal (UE A) de passer d'un premier à un deuxième réseau d'accès audit réseau IP; et un serveur ATCF (Access Transfer Control Function) en charge dudit premier terminal (UE A) fait parvenir à un serveur d'application SCC-AS (Service Centralization and Continuity), via un serveur IBCF (Interconnection Border Control Function), une requête apte à informer ledit serveur d'application SCC-AS qu'une procédure de transfert de réseau d'accès a été initiée pour le premier terminal (UE A). Selon l'invention, ladite requête est agencée de manière à indiquer audit serveur d'application SCC-AS qu'il ne doit pas propager cette requête vers un dispositif-client, dit deuxième terminal (UE B), appartenant lui aussi au réseau IP, avec lequel le premier terminal est en cours de communication. Application aux réseaux IMS.
