Abstract

In the field of telecommunication, different supplementary services are provided for a subscriber. Call forwarding is a service which allows the user to forward incoming calls unconditionally or based on conditions (e.g. when busy, not reachable, etc.). Anyhow, the services offered to the subscribers till now had certain limitations, which are pointed out in the following scenario (for example). Activating merely the feature Call Forwarding (CF), subscriber X does not have any control on the forwarding of other subscribers' calls to his mobile phone: a) Subscriber X can not differentiate/distinguish in forwarding his direct/normal calls on the one hand and the forwarded calls to him on the other hand. b) When subscriber X is in a meeting, he may not want to receive forwarded calls, but he would like to receive direct/normal calls. c) While subscriber X is roaming, he has to pay for the forwarded calls from other persons. To amend the situation, some new supplementary services allow more control by the subscriber on forwarded calls (controlled call forwarding). The services can be named BAOC_CF, BAIC_CF and BAIC_ROAM_CF and offer the following functions:

c) While subscriber X is roaming, he has to pay for the forwarded calls from other persons.

To amend the situation, some new supplementary services allow more control by the subscriber on forwarded calls (controlled call forwarding). The services can be named BAOC_CF, BAIC_CF and BAIC_ROAM_CF and offer the following functions:
