Terminal node controller

Abstract: A device receives information about signals detected by an access terminal, a first one of the signals corresponds to a radio node with which the access terminal is in communication, and if a second signal detected by the access terminal does not correspond to signals in use by the radio node and the access terminal, and if a condition is met, the devise causes the access terminal to alter communication with the radio node.

Abstract: A method of packet transfer is provided to resolve the problem of fraudulent access to user LANs through falsified source address so that only those pre-registered terminals are permitted to transfer packets with specific data networks. Each user LAN is assigned an identifier to identify respective user LAN beforehand. Packet network stores terminal information including terminal addresses, identifiers assigned to one and more user LANs that are permitted to communicate with each packet terminal and information necessary for terminal authentication beforehand. When the packet terminal starts a communication through a base station, the packet network authenticates the packet terminal, and if it is an unauthorized terminal, the packet network informs a denial for communication to the packet terminal. If an allowance for communication is obtained by authentication, the packet terminal encrypts data to be transmitted and sends a packet to the packet network with an attachment containing the encrypted data, identifiers for the selected user LAN among one and more user LANs, the destination address and the source address. Packet network receives the packet, and while decoding the encrypted data included in the received packet, detects tampering, and if tampering is detected, the received packet is discarded, but if there is no tampering, it checks whether the identity of source address and the identifier is registered in the terminal information, and if the identity is registered, the received packet is sent to the destination address, and if the identity is not registered, the received packet is discarded.

Abstract: A method (82, 162), and associated apparatus (10), for the selective transmission of packet data to a mobile terminal (14) operable in a radio communication system (10). When packet data is to be terminated at the mobile terminal (14), an SMS (short message service) message is first transmitted (168) to the mobile terminal (14) (104, 112, 114). A determination is made at the mobile terminal (14) whether to permit transmission of packet data thereto (124, 174). The packet data is transmitted (176) to the mobile terminal (14) if permission is granted by the mobile terminal (14).

Abstract: Techniques for initiating a backhaul connection between a radio node controller and a packet data serving node of a radio access network based on a determination of a presence of a packet data session on an access terminal. Techniques for enabling a dormant access terminal in communication with a radio access network to maintain a point-to-point (PPP) session with a packet data serving node as the dormant access terminal moves from a coverage area associated with a first radio node controller to a coverage area associated with a second radio node controller prior to a completion of a backhaul connection setup by the first radio node controller.
