Abstract: The present invention is a novel and improved method and system that prevents RLP3E from generating unnecessary NAKs, thus preventing unnecessary data frame retransmissions. The present invention is efficient, neither delaying the delivery of data frames to the higher data services layer nor delaying the delivery of necessary NAKs to the multiplex sublayer. Additionally, the present invention can be implemented with minimal changes to an existing RLP3E implementation. The present invention is applicable to systems such as cdma2000, W-CDMA, and EDGE, wherein data is transferred using an ARQ (automatic request for retransmission) mechanism, and wherein data packets are sometimes received in an order different from that in which they were transmitted.

Abstract: A wireless communication device and a method for transmitting and receiving at least one frame between a terminal device, connected to the wireless communication device, and an interworking function. Selected ones of a plurality of corresponding configuration options of a first and a second instance of a communication protocol, executing on the wireless communication device, are checked 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 the wireless communication device without unframing and reframing the communication protocol frames encapsulating the packets.

Abstract: An improved method and system for transmitting a stream of data bytes through a channel (506A, 506b) whose capacity may change during transmission. By utilization of selective regions of sequence number space, the enhanced radio link protocol (RLP) (140, 142, 144) provides the benefits of large byte sequence numbers while transmitting a fraction of the sequence number bits in the majority of over-the-air frames. Frame header sequence numbers are shortened by dividing the byte sequence number by a page size, and by performing a modulo function on the byte sequence number.

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 communicaton system, and a wireless MT2 device (104) 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 (104) is handed off to a new BS/MSC (106), the Um interface will undergo PPP configuration renegotiation (Figure 4) without causing the Rm interface also to undergo PPP configuration renegotiation. Similarly, when t he Rm interface undergoes PPP configuration renegotiation (Figure 6), the Um interface will not undergo PPP configuration renegotiation.

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: Se revela un método para la determinación anticipada del soporte de la red para IP móvil en un sistema de comunicación inalámbrico. Un nodo móvil está en comunicación con una red inalámbrica. Entonces se realiza una prueba para una condición de desconexión donde la condición de desconexión es una indicación anticipada del no-soporte de la red para el IP móvil según lo identificado por al menos un requisito para la autentificación. La indicación anticipada se relaciona con la identificación del no-suporte para el IP móvil antes o durante la conexión del paquete de la red. Si se encuentra la condición de desconexión, el nodo móvil se desconecta de la red inalámbrica. Si la condición de desconexión no se encuentra, el nodo móvil permanece conectado a la red inalámbrica.

Abstract: A novel method and apparatus is disclosed for performing seamless handoff of a mobile station (MS) between Radio Access Networks (RANs) that use different types of wireless interfaces. The described embodiments enable an MS to handoff between different RANs without causing routing ambiguity, and without substantial loss of network data. Upon moving from the coverage area of a first RAN using a first wireless interface to the coverage area of a second RAN using a second wireless interface, an MS determines whether routing ambiguity may result from the change of RAN and, based on the determination, triggers a re-registration of its network address. A foreign agent (FA) within a packet data serving node (PDSN) monitors network address re-registrations in order to determine whether multiple RAN-PDSN (R-P) connections are being created for the same MS. Based on this determination, the PDSN terminates redundant R-P network connections resulting from movement of the MS between different RANs.
