  • Patent number: 6587674
    Abstract: The present invention relates to the field of arrangements and methods by a mobile transceiver. The invention solves the problem of how to obtain a mobile telephone terminal (21) with a lid (25) and a corresponding function with automatic reception of an incoming call when the lid (25) is opened, such as a mobile telephone terminal with an active lid, where also such services are to become available that need access to a keypad (29) covered by the lid (25) and which allows a user to handle the incoming call in other ways than only receiving the call. The problem is solved in that the mobile telephone terminal (21) comprises means (41) that enable the user on demand to deactivate the automatic reception of the incoming call.
