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 the 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 data services nodes are optimized by reducing the information included in messages 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: 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 technique is described for determining configuration options negotiated fo r a wireless communications link employing a network model. The technique receives an input data stream from a wireless communications link employing a network model, the network model operating, e.g. to isolate an PPP-Rm link from an PPP-Km link. The input data stream includes one or more framed data packets containing information. The wireless communications link employing t he network model is based on configuration options negotiated. The framed data packet(s) from the input data stream are detected and at least a portion of the information of the detected framed data packet(s) is examined when the configuration options of the wireless communications link employing the network model have been negotiated. In an embodiment, the IPCP configuration options like e.g. IP-address, Van Jacobson compression and Van Jacobson compression slot ID are determined by examining a portion of information of a predetermined number of framed data packets when the configuration options have been negociated.

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 present invention discloses a method and apparatus for detecting a specified event in a wireless communication system. The present invention includes an application program interface (API) that facilitates communications between a mobile station communication protocol stack, which communicates with a communication network, and a mobile station application. The mobile station communication protocol stack polls a memory when the mobile station application registers a specified event. Based on the polling, the mobile station communication protocol stack then detects the specified event. In another implementation of the present invention, the mobile station communication protocol stack detects the specified event by an interrupt notice, which is triggered when the specified event occurs.
