Patent

CA 2229636

The invention relates to a visitor location register and a method for handling an outgoing and an incoming call in a mobile communications system employing a multinumbering scheme. Signalling originating from a mobile services switching centre (MSC) contains in case of a mobile-originating call the directory number of the calling subscriber and in call forwarding, the redirecting number. This directory number is obtained from the visitor location register (VLR). In accordance with the invention, all the directory numbers for different basic services of the mobile subscriber are transferred from the home location register (HLR) to the VLR. The VLR is thus capable of providing the MSC with the correct one of multiple directory numbers according to the basic service related to the call.

L'invention concerne une mémoire des positions des utilisateurs occasionnels et un procédé de traitement d'appels entrant et sortant dans un système de radiocommunications mobile, dans lequel un principe de multinumérotation est utilisé. La signalisation provenant d'un central de service mobile (MSC) contient, lorsque l'appel provient d'un équipement mobile, le numéro de téléphone de l'abonné appelant et, lors du renvoi d'appel, le numéro de renvoi. Ce numéro de renvoi est obtenu dans la mémoire des positions des utilisateurs occasionnels (VLR). Dans le procédé selon l'invention, tous les numéros de téléphone pour les différents services de base des abonnés au téléphone mobile sont transférés depuis la mémoire des positions des utilisateurs permanents (HLR) à la VLR, laquelle est ainsi capable de fournir au central de service mobile (MSC) le numéro de téléphone approprié parmi les numéros multiples, en fonction du service de base relatif à l'appel.
