Title
(EN) NOTIFYING ROAMING SUBSCRIBER OF MISSED CALL
(FR) NOTIFICATION D'APPEL EN ABSENCE À UN ABONNÉ ITINÉRANT
Abstract
(EN)
In a first node of a home network, such as a GMSC, on receiving a request message (50), requesting call set-up to a called terminal, a message (52) is sent to a second node of the home network, such as an HLR, to obtain an address of a mobile switching centre where the called terminal is located. On receiving a reply (58) from the second node, the first node initiates (60) a missed call notification service if it is determined that the called terminal is in a visited network. The first node then initiates a call set-up (64) to the called terminal and, if it is notified that the call has been released (66), with no call forwarding having taken place, it notifies (68) the missed call notification service that the call has been released. The missed call notification service causes (72) a message to be sent (74) to the' called terminal, notifying it of the missed call.
(FR)
Selon l'invention, dans un premier nœud d'un réseau mère, tel qu'un GMSC, lors de la réception d'un message de requête (50) demandant l'établissement d'une communication avec un terminal appelé, un message (52) est envoyé à un second nœud du réseau mère, tel qu'un HLR, afin d'obtenir l'adresse d'un centre de commutation mobile au niveau duquel le terminal appelé est localisé. Lors de la réception d'une réponse (58) du second nœud, le premier nœud déclenche (60) un service de notification d'appel en absence s'il est déterminé que le terminal appelé se trouve dans un réseau visité. Le premier nœud déclenche alors un établissement de communication (64) avec le terminal appelé et, s'il lui est notifié que la communication a été libérée (66), sans qu'un renvoi automatique d'appel ne se soit déroulé, il notifie (68) au service de notification d'appel en absence que la communication a été libérée. Le service de notification d'appel en absence provoque (72) l'envoi d'un message (74) au terminal appelé, lui notifiant l'appel en absence.
