METHODS FOR PROCESSING AN OUTGOING AND AN INCOMING CALL IN A MOBILE COMMUNICATIONS SYSTEM

摘要

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.
