PCT No. PCT/FI95/00704 Sec. 371 Date Jun. 20, 1997 Sec. 102(e) Date Jun. 20, 1997 PCT Filed Dec. 21, 1995 PCT Pub. No. WO96/20554 PCT Pub. Date Jul. 4, 1996A mobile services switching center for forwarding a subscriber directory number terminating call to a call forwarding number which is retrieved from a separate subscriber database. The mobile services switching center contains a call forwarding database which stores directory numbers of forwarding parties from each of which a set-up of a forwarded call is in progress. The call control of the mobile services switching center is arranged to check, prior to initiating call forwarding, whether a directory number of the forwarding party is included in the call forwarding database. The call control of the mobile services switching center is further arranged to release the call in response to the directory number of the forwarding party being included in the call forwarding database, in order to avoid looping of the call due to the call forwarding, and, in response to the directory number of the forwarding party not being included in the call forwarding database, to insert the directory number of the forwarding party in the call forwarding database, and to continue the call forwarding.
