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: A system and method for transparent Mobile IP registration within PPP negotiation uses a mobile telephone to relay messages between terminal equipment and a Foreign Agent (FA). An IPCP configuration request message by the terminal equipment requesting the assignment of an IP address is modified by the mobile telephone to delete the IP address request option. Other configuration options are forwarded unchanged by the mobile telephone to the peer/network. The peer/network responds with an acknowledgement of the requested configuration options and flow control between the terminal and the MT is asserted to permit Mobile IP registration. In the course of Mobile IP registration, and IP address is assigned to the mobile unit by the FA. Upon completion of the Mobile IP registration, flow control between the mobile telephone and the terminal is deasserted and the IP address assigned during Mobile IP registration is provided to the terminal equipment. In addition, the previously requested options may also be acknowledged.

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 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 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 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.
