Abstract: An improved method and system for terminating dormant mode wireless packet data sessions when a remote network node becomes inaccessible. A wireless subscriber station sends the wireless network a termination notification identifying a packet data session corresponding to a remote network node that has become inaccessible and should be terminated.

Abstract: A method for selectively maintaining a compression state and applying a compression technique after a PPP renegotiation on a U m interface of a wireless communication network. A communication device (104) receives packetized data transmitted from a terminal device (102) which is coupled to the communication device via an R m interface. The communication device determines (S315) whether the received packetized data comprises compressed or uncompressed data. Upon determining that the received packetized data comprises compressed data, the communication device determines (S340) whether connection information exceeds a highest numbered decompression slot from a plurality of decompression slots on said U m interface. The communication device sets up (S330) a local decompression slot, in the communication device, which corresponds to the connection information in order to maintain said compressionsate, wherein the local decompression slot is set up in response to determining (S325) that the connection information exceeds the highest-numbered decompression slot. The communication device decompresses (S350) the compressed packetized data when it receives compressed packetized data containing said connection information.

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: 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: 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 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: 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 f or 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. Wh en 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 sequen ce 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, a n RLP re-sync is avoided due to out of order RLP sync packets.

Abstract: A method and system that detects protocol and configuration messages in a PPP packet without having to unframe the entire packet. The method includes a communication device that receives a plurality data frames, wherein the communication device is capable of ascertaining the beginning of an information portion 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 the contents of a plurality of bytes and determining 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 communication device continues to sequentially process the bytes within the information portion until the bytes typically containing the desired configuration information are processed.
