Abstract: The present invention discloses a method and apparatus for a mobile station application to receive and transmit raw packetized data in a wireless communication system. The present invention includes a mobile station application that creates at least one socket. At least one of mobile station protocol layers of a communication protocol stack receives encapsulated raw packetized data from a communication network. The raw packetized data lacks destination port information. At least one of the mobile station protocol layers transmits unencapsulated raw packetized data to the created sockets. In turn, the created sockets transmit the raw packetized data to the mobile station application. In another implementation, the created sockets transmit raw packetized data of the mobile station application to at least one of the mobile station protocol layers. In turn, at least one of the mobile station protocol layers transmits encapsulated raw packetized data to the communication network.

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: 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: In a wireless communication system, a method for early determination of network support for Mobile IP is disclosed. A mobile node is in communication with a wireless network. Then a test is performed for a disconnect condition wherein the disconnect condition is an early indication of network non-support for Mobile IP as identified by at least a requirement for authentication. Early indication relates to identification of the non-support for Mobile IP prior to or during network packet connection. If the disconnect condition is found, the mobile node disconnects from the wireless network. If the disconnect condition is not found, the mobile node stays connected to the wireless network.

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.

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 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.
