Abstract: A mobile packet network call is established over a transmission link, extending between a mobile terminal device and a given interworking function. The transmission link connects the mobile terminal device to a wireless communication device over a first interface and further connects the wireless communication device to the given interworking function over a second interface via a wireless link to a base station. The transmission link further comprises a packet mode in which the traffic channel is up and a dormant mode in which the traffic channel is down while the data link layer link and the network layer link are maintained. Network region identifier information is provided to the wireless communication device. The wireless communication device determines when the given interworking function has changed from a first interworking function to a second interworking function by determining when there is a corresponding change in the network region identifier information. The wireless communication device initiates a link control protocol renegotiation with the mobile terminal device when the corresponding change in the network region identifier information has been determined. The mobile terminal device responds to the initiation of the link control protocol, and causes the transmission link to enter the packet mode, and to bring up the traffic channel. The data link layer link is then established with the second interworking function. The mobile terminal device and the second interworking function then negotiate network control protocol options and establish a network layer link. If the second interworking function corresponds to a new foreign agent, the mobile terminal device will then update its IP mobility registration.

Abstract: A method and apparatus for allowing a mobile station (110) in a wireless network to perform network authentication in association with mobile packet data services. The packet data serving node (PDSN) does not authenticate the mobile station with an authentication server prior to sending a CHAP success message. Rather, a mobile station is authenticated via an authentication server after the PDSN (130) receives an IPCP message indicating whether the mobile station desires to use Mobile IP in the current session. If the mobil e station (110) desires to use Mobile IP, the PDSN (130) uses authentication techniques in accordance with Mobile IP protocols. In the preferred embodiment, if the mobile station (110) does not desire to use Mobile IP, th e PDSN (130) authenticates the mobile station querying an authentication serve r with the buffered contents of a previously received CHAP challenge response.

Abstract: A method and system that prevents RLP3E from generating unnecessary NAKs, th us preventing unnecessary data frame retransmissions. A mechanism is interposed between the multiplex sublayer and the RLP3E layer for all incoming traffic. The frame reordering sublayer (346), reorders the received packets into the order in which they were transmitted prior to delivering them to the RLP3E layer (344). The frame reordering sublayer (346) reorders frames received by the multiplex sublayer by determining the order in which physical layer fram es were transmitted by its peer, and by buffering each received frame until all frames transmitted prior to it have been received.

Abstract: A method and system that detects protocol and configuration messages in a PP P packet without having to unframe the entire packet. The method includes a communication device (MT2) that receives a plurality data frames (S306), wherein the communication device is capable of ascertaining the beginning of an information portion (S305) within the received frames. The communications device detects whether the information portion contains configuration information, such as protocol and configuration messages of a predetermined type. In a first embodiment, the detection is achieved by the communication device unescaping (S315) the contents of a plurality of bytes and determinin g (S325, S330, S335) whether the escaped bytes contains the desired configuration information. In a second embodiment, the communication device determines whether the contents of a particular byte contain the desired configuration information, in escaped or unescaped form, and the communicati on device continues to sequentially process the bytes within the information portion until the bytes typically containing the desired configuration information are processed.

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: 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: 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: The packets generated by each of multiple packet data applications are provided to a single Point-to-Point Protocol (PPP) stack (202) and a single High-level Data Link Control (HDLC) framing layer (204) 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 (206 and 208). 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 (218 and 216) is provided to a single PPP stack (210).
