    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 portable ladder having stabilizer brackets slidably mounted on the ladder siderails to permit the ladder to be mounted to a flatbed trailer tiedown rail. The slidable stabilizer brackets are substantially self-adjusting in position, and adjust automatically, for example, when a load is removed from the trailer. The ladder may optionally include two sections pivotably interconnected to facilitate handling and storage. A lock to secure the two sections together in an extended position may also be provided. The advantage is a lightweight, portable ladder which can be used with practically any flatbed trailer. The ladder adjusts substantially automatically to the height of the trailer to provide stable access to the trailer bed.

    Abstract: A method for detecting delayed data frames in a transport function includes the steps of comparing a frame sequence counter with a predetermined threshold value (304), detecting a delayed frame if the sequence counter exceeds the threshold value, and processing the detected delayed frame accordingly (306). In an RLP data transport protocol, the delayed frame may be processed as a retransmitted frame. The threshold value may be proportional to the maximum number of frames sent in a given bundle times the maximum delay, in units of frame intervals, between frames sent simultaneously over the air in the same frame interval.

    Abstract: A system ( 100 ) and various methods and apparatus for efficient communications of data across various protocol layers are disclosed. The system ( 100 ) includes a base station ( 101 ) for receiving radio link protocol (RLP) packets of data over a physical layer protocol. A processor ( 401 ) is configured for passing, to a higher level protocol in network ( 105 ), the received in-sequence RLP packets of data, from the accumulated data in a re-sequencing buffer ( 480 ), without waiting for receiving retransmission of a missing RLP packet of data when the accumulated RLP packets of data exceeds an amount of data threshold without waiting for an elapsed time of an abort timer to exceed an abort period of time threshold.

    Abstract: A method for delivering SMS to ATs in a first communication network providing DO and 1x interfaces and for offloading the delivery of the SMS from a second communication network including an MSC, comprising monitoring a DO control channel for pages by an AT and delivering the SMS in SIP to the AT over the DO interface. The method may further comprise tuning the AT to the DO interface and determining whether the AT is SIP registered for using the DO interface. An application server determines whether the AT is SIP registered for using the DO interface. When the DO interface is not available, the SMS may be delivered over the 1x interface and the method further comprises the AT sending a special SMS to an SMS gateway, which causes the application server to remember that the AT is now monitoring the first communication network including a circuit-switched network.
