Abstract: A method and a wireless communication device (104) capable of flow controlling data to be sent from a TE2 device (102) over a R m interface when PPP renegotiation occurs over a U m interface. Flow control (S320) is asserted by the MT2 device (104) by means of manipulating electrical signaling of a physical interface between the MT2 device (104) and the TE2 device (102). A second embodiment provides a method and a wireless communication device (104) for buffering (S420) data on the MT2 device when the PPP renegotiation of the U m interface occurs. In a third embodiment, data is buffered when the PPP renegotiation of the U m interface occurs. When an amount of free buffer space is less than a predetermined threshold (S540), flow control is asserted (S550) to the TE2 device.

Abstract: A networked device shares a single IP address with a separate networked device. The networked device examines a port number of a received IP packet. The networked device routes the IP packet to an application on the networked device if the port number of the received IP packet corresponds to the application. Otherwise, the IP packet is routed to the separate networked device. The networked device also originates IP packets including as an origination address an IP address assigned to the separate networked device. Alternately, the IP address may be "shifted" to between the networked device and a separate networked device by blocking transmitted IP packets originating in the separate networked device, and originating IP packets, which include as an origination address an IP address assigned to the separate networked device.

Abstract: En un sistema de comunicacion en el cual un nodo de seguimiento que busca acceso de red entre diferentes redes el cual es ejecutado con diferentes protocolos de capa de interfaz de red, se instituyen esquemas de transferencia por medio de los cuales el nodo se puede mover libremente de una red a otra con niveles reducidos de interrupciones con respecto al acceso de red; antes de, y al momento del inicio de una transferencia, el nodo recibe una indicacion para la transferencia; la indicacion se puede incorporar en varias formas tal como un mensaje de senal que indique un cambio de la SID (Identificacion del Sistema), NID (Identificacion de la Red) o PZID (Identificacion de la Zona de Paquete); alternativamente, la indicacion puede ser en la forma de informacion directamente incluida en un paquete de datos enviado al nodo en seguimiento antes de la transferencia; como otra alternativa, la indicacion se puede ejecutar en la forma de patrones de mensaje que se pueden distinguir, enviados al nodo, en donde diferentes patrones de mensaje pueden ser enviados por diferentes redes que soportan diferentes protocolos de capa de interfaz de red.

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: A method and a wireless communication device (MT2) for simultaneously negotiating LCP or IPCP configuration options over both the Rm and the Um interfaces. When the MT2 device receives either an LCP or an IPCP Configure-Request packet over one of the Rm or the Um interfaces, the MT2 device parses the requested configuration options and determines whether the requested options are supported by the MT2 device. If the requested options are supported, the MT2 device saves a Configure-Request ID, included in the Configure-Request packet, and frames the Configure-Request packet in a PPP frame for transmission on the other of the Rm or the Um interfaces. If any of the requested configuration options are not supported by the MT2 device, the MT2 device creates a Configure-Reject packet, including the unsupported options, and frames the Configure-Reject packet in a PPP frame for transmission over the interface through which it received the Configure-Request packet.

Abstract: The packets generated by each of multiple packet data applications are provided to a single Point-to-Point Protocol (PPP) stack and a single High-level Data Link Control (HDLC) framing layer to convert data packets into byte streams suitable for transmission through Radio Link Protocol (RLP) connections. Each of the resultant multiple byte streams is then provided to one of multiple RLP connections having different retransmission and delay properties. The RLP connection selected for sending data from each application is based on the grade of service most appropriate for the application. At the receiver, the data from the multiple RLP connections is provided to a single PPP stack.

Abstract: A method, within a wireless communication system, and a wireless MT2 device which provide for the resynchronization of a PPP link on each one of a Um and Rm interface without affecting the other of the Um and Rm interface. When a handoff is performed, such that the communications of the mobile MT2 device is handed off to a new BS/MSC, the Um interface will undergo PPP configuration renegotiation without causing the Rm interface also to undergo PPP configuration renegotiation. Similarly, when the Rm interface undergoes PPP configuration renegotiation, the Um interface will not undergo PPP configuration renegotiation.

Abstract: A method for selectively maintaining a compression state and applying a compression technique after a PPP renegotiation on a U m interface of a wireless communication network. A communication device (104) receives packetized data transmitted from a terminal device (102) which is coupled to the communication device via an R m interface. The communication device determines (S315) whether the received packetized data comprises compressed or uncompressed data. Upon determining that the received packetized data comprises compressed data, the communication device determines (S340) whether connection information exceeds a highest numbered decompression slot from a plurality of decompression slots on said U m interface. The communication device sets up (S330) a local decompression slot, in the communication device, which corresponds to the connection information in order to maintain said compressionsate, wherein the local decompression slot is set up in response to determining (S325) that the connection information exceeds the highest-numbered decompression slot. The communication device decompresses (S350) the compressed packetized data when it receives compressed packetized data containing said connection information.
