A method of connecting an access point to other network elements in a wireless telecommunication system having at least one access point offering wireless connections, and at least one fixed network part, includes storing data on an IC card for connecting at least one access point to a functional connection with the fixed network part. The IC card is connected to a functional connection with the access point when the access point is to be connected to the fixed network part. Necessary resources of the fixed network part are connected to a functional connection with the access point on the basis of said stored data. As a precondition for the connection, the IC card's rights to use the resources of the fixed network part can be checked in the fixed network part.
