<p>The present invention relates to an improvement in a mobile services switching center, employed for preventing and endless call forwarding between a mobile subscriber and a subscriber located in the service area of another switching center in a case where the subscribers have activated a call forwarding to each other. It is possible to prevent endless call forwarding in a mobile services switching center by storing the directory number of the forwarding subscriber in a special-purpose database (16) during the call forwarding. The contents of the database are compared to the directory number of the forwarding subscriber in connection with every call forwarding call. If, during the checking, the directory number of the forwarding subscriber is found in the database, the call control (13) of the mobile services switching center discontinues the call set-up.</p> |
