Through a query, permission for establishing the requested type of connection is requested or a request is given to check the connection parametre. The first and/or second network element and/or the established connection or the type of connection is indicated in the query. The fourth network element returns a reply containing permission for establishing connection or type of connection, or in which the connection parametre is indicated.
