Abstract
Abstract Method and device for determining a signaling address of a mobile services switching center in a cellular communication system offering both circuit switched and packet switched services are disclose. The method is based on that, instead of using information on the location of a terminal equipment, information on the equipment of the system being used for reaching a terminal equipment is used for determining the mobile services switching center, in the service area of which the terminal equipment is located. The signaling address is determined on the basis of the knowledge of such information. For this purpose, for instance, allocation tables or sorting trees are used, which allocate the sought for signaling address to one or more equipment or to an information identifying one or more equipment.
