Abstract
The invention relates to a method for call set-up and a telecommunication system. The telecommunication system comprises service database means (10, 20, 30 and 40) comprising teleservice price data. The service database means (10, 20, 30 and 40) are connected to different service provider means (15 to 17, 25, 26, 35, 45, 46) representing various operators. A control means (11, 12, 21 to 23, 31 to 33, 41 and 42) is in connection with the subscriber terminal of the telecommunication system, and is regularly, or at a preferred time, in connection with the service database means (10, 20, 30 and 40) for transmission of service information to the control means (11, 12, 21 to 23, 31 to 33, 41 and 42). The control means (11, 12, 21 to 23, 31 to 33, 41 and 42) controls the call set-up of the subscriber terminal so that the subscriber uses the operator (15-17, 25, 26, 35, 45, 46) offering the most inexpensive teleservice. To further increase the efficiency, the service database means (10, 20, 30 and 40) form their own service areas, which are connected to each other as a network.
