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: To mitigate re-syncs, RLP sync control frames associated with a packet data session can be sequence numbered. A single sequence number can be assigned for an entire sync procedure associated with the initiation of a packet data session. For example, the sequence number can remains the same on all sync control frames (SYNC, SYNC/ACK, ACK) of a particular packet data session. When a sync frame is received out of order within a single sequence, it can be ignored under certain conditions. For example, if a SYNC frame with a sequence number 0 is received out of order after an ACK frame with sequence number 0 is received, the mobile station can ignore the out of order SYNC frame. Thus, an RLP re-sync is avoided due to out of order RLP sync 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: In order to assist an exchange of data between one or mobile communications devices and the Internet in a mobile communications network, bidirectional tunneling of IPv6 messages inside IPv4 messages is performed between a home agent and one or more foreign agents. Optionally, where a mobile communications device is a wireless mobile unit, the mobile unit itself automatically engages in bidirectional tunneling of IPv6 messages inside IPv4 messages with the home agent whenever the wireless mobile unit detects loss of wireless coverage in the mobile communications network and presence of coverage in a type of wireless network lacking foreign agent functionality.

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: An HDLC accelerator includes a deframer and framer to respectively accelerate the deframing and framing processes for PPP packets. The deframer includes an input interface unit, a detection unit, a conversion unit, and an output interface unit. The input interface unit receives a packet of data to be deframed. The detection unit evaluates each data byte to detect for special bytes (e.g., flag, escape, and invalid bytes). The conversion unit deframes the received data by removing flag and escape bytes, “un-escaping” the data byte following each escape byte, providing a header word for each flag byte, and checking each deframed packet based on a frame check sequence (FCS) value associated with the packet. The output interface unit provides deframed data and may further perform byte alignment in providing the deframed data. A state control unit provides control signals indicative of specific tasks to be performed for deframing.

Abstract: A method and apparatus for conserving home agent resources in mobile Internet Protocol (IP) deployment is disclosed. In a wireless communication system supporting mobile IP, a release candidate set is generated and updated during operation of the network. When an inactivity timer associated with a mobile node satisfies a condition, the mobile node is listed in the release candidate set. Successful communication with the mobile node results in removal from the release candidate set. The release candidate set is accessed when a home agent desires to reclaim resources on an overload condition.
