FOERFARANDE FOER ATT MELLAN CENTRALER OEVERFOERA BEHANDLINGEN AV EN AKTIV FOERBINDELSE MELLAN AO ENA SIDAN EN ANVAENDARE OCH AO ANDRA SIDAN EN MOBILTERMINAL

摘要

Known methods of transferring between centres the handling of an active connection between a user and a mobile terminal in a telecommunication system designed for mobile communication generally have the disadvantage that the routing obtained is inefficient. By investigating both a first route between a first switching centre and the user and a second route between a second switching centre and the user for common centres which are able to handle call control and connection control separately, of which the common centre situated nearest the first switching centre is designated as central intelligence point or, if the latter is not found, by designating the centre situated nearest the user as central intelligence point and then setting up a connection between a central intelligence point found in this way and the second switching centre, the most efficient routing is obtained.
