<p>A method for a location update in a mobile communication system with a home location register (HL) and visitor location registers (VL) is described. The visitor location registers (VL) serve different parts of the area covered by the communication system and the home location register (HL) holds a data record assigned to a user, the data record comprising parameters for the establishment of connections with the user and an identification of the visitor location register (VL) presently serving the user. Parameters from the record can be copied from the home location register (HL) to the visitor location register (VL) serving the user. In the method it is detected that a user has entered the area served by a visitor location register (VL) and a location update message (18) is sent which indicates the identity of the visitor location register (VL) to the home location register (HL) and stored in the data record for the user. When the establishment of a connection with the user is requested, parameters from the data record in the home location register (HL) are sent to the serving visitor location register (VL) during the establishment of the connection. Location registers and programs embodying the invention are also described.</p> |
