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: Systems and techniques are disclosed relating to wireless communications. The systems and techniques involve monitoring a first network in accordance with a first air interface, and receiving a message from a second network through the first air interface, the second network being associated with a second air interface different from the first air interface. Various registration and related techniques are also discussed for maintaining connectivity with both networks as the wireless communications device moves through different geographic coverage regions.

Abstract: Micro-tunnels are used to provide multiple data service sessions to the same mobile node in a wireless communications system. Further, the flexibility of the micro-tunnels optimizes the resources of the system. On request for a data service, an encapsulation configuration record is generated. An encapsulation header is created in response to the encapsulation configuration. The encapsulation header includes a packet service identifier and a micro-tunnel identifier.

Abstract: A method and apparatus for requesting PPP instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of the new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each such PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant (i.e., whether the mobile station is engaged in a call).

Abstract: In a method and system for monitoring a control channel in a telecommunication system, the transmission of the overhead parameters is separated from the transmission of the packets that are directed to an access terminal. Consequently, the access terminal may need to monitor a control channel for a shorter period of time if a current message indicates that the received set of overhead parameters is up to date. In this case, the access terminal with up-to-date overhead parameters may stop monitoring the control channel before the end of a synchronous capsule time period. Otherwise, the access terminal may continue to monitor the control channel until an up-to-date set of overhead parameters is received.

Abstract: For efficient communications of data across various protocol layers in a communication system (100), a base station (101) receives radio link protocol (RLP) packets (509) of data over a physical layer protocol (505). A processor (401) assembles received RLP packets (509) of data. The processor (401) is configured for determining whether a received RLP packet (509) of data is received out of sequence in a series of RLP packet (509) of data, starting an abort timer associated with a transmitted negative acknowledgment for measuring an elapsed time of the abort timer, determining whether the elapsed time of said abort timer exceeds an abort period of time dynamic threshold that is based on statistical data of periods of time measured for previously received successful retransmissions of RLP packet (509) of data.
