The object of the invention is a system, a device, a terminal and a method for filtering electronic information to be transferred to the terminal through a telecommunication connection. The invention comprises attaching a specific filtering parameter (30-32) by the device transferring the electronic information to the electronic information for the purpose of filtering before the electronic information is transferred to the terminal through the telecommunication connection, and informing the terminal of said filtering parameter (30-32) before the electronic information is transferred to the terminal through the telecommunication connection. In the terminal, the steps comprise checking said informed filtering parameter (30-32) and allowing or preventing the receiving of the electronic information on the basis of said filtering parameter (30-32). In response to said allowing of the receiving, the electronic information is transferred to the terminal through the telecommunication connection, and in response to said preventing of the receiving, the electronic information is not transferred to the terminal through the telecommunication connection. |
