Endless call reforwarding in a mobile service exchange center can be prevented by memorizing directory number of reforwarding subscriber in special purpose database (16) during call reforwarding. The content of database is compared with the directory number of reforwarding subscriber in relation to each call reforwarding call. When the directory number of reforwarding subscriber is found in the database during checking time, a call controller (13) of mobile service exchange center interrupts call setting.
