    Abstract: A method and apparatus for requesting PPP instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of th e new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each such PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant (i.e., whether the mobile station is engaged in a call). Communications channel resources of packet da ta services nodes are optimized by reducing the information included in message s from the Packet Control Function network element to the Packet Data Service Node network element, and by reducing the use of Mobile Internet Protocol agent advertisement.

    Abstract: An apparatus (102, 104) for transmitting a stream of information bytes, the apparatus (102, 104) includes a mechanism (604, 618, 638) for receiving/transmitting a message specifying a radio link protocol, RLP, round-trip time, RTT, estimate, and a mechanism (604) for conducting an RLP communication session using said RTT estimate to determine negative acknowledgment, NAK, message timing. A first RLP RTT estimate can be established during service negotiation, and is used to determine NAK message timing in a subsequent RLP communication session. Alternatively, a 3-way handshake is performed for generating a first RTT estimate associated with the first RLP communication session, a second RTT estimate, based on the first RTT estimate, associated with a second RLP communication session is established during service negotiation. The second RLP RTT estimate is used to determine NAK message timing in a subsequent RLP communication session.

    Abstract: A method and a wireless communication device capable of flow controlling data to be sent from a TE2 device over a Rm interface when PPP renegotiation occurs over a Um interface. Flow control is asserted by the MT2 device by means of manipulating electrical signaling of a physical interface between the MT2 device and the TE2 device. A second embodiment provides a method and a wireless communication device for buffering data on the MT2 device when the PPP renegotiation of the Um interface occurs. In a third embodiment, data is buffered when the PPP renegotiation of the Um interface occurs. When an amount of free buffer space is less that a predetermined threshold, flow control is asserted to the TE2 device.

    Abstract: A wireless communication device and a method for transmitting and receiving at least one frame between a terminal device (102), connected to the wireless communication device (104), and an interworking function (108). Selected one s of a plurality of corresponding configuration options of a first and a secon d instance of a communication protocol, executing on the wireless communicatio n device, are checked (S510) to determine whether they are equal. If the selected ones of the corresponding configuration options are equal, all but certain ones of a plurality of packets may be passed through (S610, S620) th e wireless communication device without unframing and reframing the communication protocol frames encapsulating the packets.

    Abstract: A method or system (10) establishes a packet network call over a transmissio n link extending between a mobile terminal device (12) and an interworking function (18) which comprises a gateway or bridge connection to a network, such as a packet network. The transmission link connects the mobile terminal device (12) to a wireless communication device (14) over a first interface (Rm) and further connects the wireless communication device to the interworking function over a second interface via a wireless link (Um) to a base station (16). The packet network call, once established, comprises a first interface data link formed within a predetermined data link layer acro ss the first interface (Rm) and a second interface data link formed within the predetermined data link layer across the second interface. A flow control is asserted (304) and deasserted (310) on the mobile terminal device (12). Duri ng the flow control, the wireless communication device performs a linked contro l protocol negotiation with the interworking function to establish the second interface data link with the interworking function (18). After the second interface data link is established, and during the flow control, the wireles s communication device (14) performs a network control protocol negotiation wi th the interworking function to establish a second interface network link carri ed by the second interface data link.

    Abstract: For Mobile IP supporting inter-technology handoffs, a logical interface is provided at an abstraction layer, which resides between a network layer and a link layer. The logical interface performs processing to provide an interface between the network layer and the link layer, but communicates with physical interfaces instead of directly with the link layer. One physical interface is provided for each communication network (e.g., each radio network of a different wireless technology). Each physical interface performs technology-dependent processing for the associated communication network and communicates with a respective link layer module. Each link layer module performs link layer processing for the associated communication network. The logical interface is associated with one physical interface at any given moment. The logical interface is also associated with an IP address that does not change and is used by IP in the network layer for communication with the multiple communication networks.

    Abstract: A system and method for determining when to answer an incoming packetized data call generated from a base station in a wireless communication network. The system includes a communication device (MT2), which interfaces with the wireless communication network, and a terminal device (TE2), which is electronically coupled to the communication device and is capable of transmitting and receiving packetized data. The communications device (MT2) answers (530) the incoming packetized data call from the base station in response to detecting a control signal or control information indicating the ready-state of the terminal device. This terminal device ready-state indicator may include control signals such as a high-state data transmit ready signal or the low-state to high-state transition of the data transmit ready signal after a ring-indicator signal has been activated to alert a subscriber of the incoming call. the ready-state indicator may also include control information such as a point-to-point protocol packetized data indicator flag, embedded in the data stream generated from the terminal device, or other information indicating that a point-to-point protocol packet was sent by the terminal device.
