Abstract:
1. A method for activating a packet data protocol context in a wireless telecommunication system comprising at least one terminal and at least one network element, the network element being configured to deliver packets between the wireless telecommunication system and other packet data networks, the method comprising: storing direction-specific service conditions in the telecommunication system for packets received by the network element and designated to at least one terminal, the direction-specific service conditions determining what kind of service is provided for packets received from different directions, determining, by the network element, the direction from which a packet to be delivered to the terminal was received, checking the direction-specific service conditions relating to said determined direction of the packet, activating the packet data protocol context if the direction-specific service conditions allow packet data protocol context to be activated for the packet; and denying the packet data protocol context if the direction-specific service conditions do not allow the packet data protocol context to be activated for the packet if received from a prohibited direction.
