Thereafter, the target foreign agent can close the tunnel between the target foreign agent and the anchor foreign agent.

Abstract: In exemplary embodiments of this invention context transfers (static and dynamic) are optimally performed to maintain the same quality of service (QoS) for a Mobile Station (MS) during a CDMA inter-BS hard handoff, as well as during a CDMA inter-BS soft handoff. Context transfers (static and dynamic) are also optimally performed to maintain the same QoS for the MS during a CDMA inter-Packet Control Function (PCF) hard handoff.

Abstract: In an exemplary embodiment of this invention contexts are transferred at an appropriate time depending on the context type. As a result, link layer (PPP) delay can be substantially eliminated during Mobile IP handoff, without introducing additional packet loss. By way of example, all MS contexts (both static and dynamic) are maintained during the inter-PDSN handoff procedure, and any executing applications are not impacted by the inter-PDSN handoff.

Abstract: Apparatus, and an associated method, for facilitating communication of data in a packet radio communication system to effectuate a packet communication service in which packet data is communicated at a variable, selectable rate. A detector embodied at an RLP layer detects channel allocations and channel reaollcations, granted to the mobile station to effectuate the data communication service. A report is generated at the RLP layer and forwarded to the TCP layer. At the TCP layer, selection is made of the TCP window to match the rate at which data is provided to the RLP layer to the rate, based upon the channel allocations provided to the mobile station, at which the data is communicated therefrom.

Abstract: A method and system for improving the efficiency of radio communication by optimizing at the radio link protocol (RLP) layer. When TCP segments are passed down from the TCP layer at a sending device, they are accompanied by TCP segment information such as TCP segment length or TCP segment number. The RLP layer receiving the data stores the TCP-segment information along with the data, and divides the data into frames for transmission. Using the TCP information, when the RLP layer receives a NAK indicating loss of an RLP frame for which retransmission will not occur, the RLP layer drops not only that frame, but also any other buffered frames associated with the same TCP segment with which the lost frame was associated, regardless of whether the other frames have been transmitted.

Registering includes sending a Network Access Identifier NAI of the MS and an Internet Protocol IP address of the Content Proxy Server to the CN from the MS, where the data sent from the CN to the Content Proxy Server includes the NAI, and where the Content Proxy Server determines the current location of the MS by sending a query to a home Authentication, Authorization and Accounting AAA server (80), the query comprising the NAI.

Abstract: A method is disclosed to operate a wireless network (20) with a MS (100) and includes, in response to detecting that the MS has changed its location in the wireless network, registering the MS with a BS (45) to indicate the current location of the MS and, in response to the MS registering with the BS, triggering the sending of messages in the wireless network until information that is indicative of the current location of the MS is recorded by an AAA server (80). The AAA server can be subsequently queried top obtain the current location of the MS, such as when a network initiated data session (NIDS) for the MS is initiated. Also disclosed is a method to page a MS by, in response to the initiation of a NIDS for the MS, querying a home AAA server for a current BS/PCF/PDSN affiliation of the MS and sending a page message to the MS in accordance with the current BS/PCF/PDSN affiliation of the MS.

Abstract: The carrier determination algorithm (CDA) used in multi carrier traffic allocation in mobile wireless digital telephony is enhanced. Access failure rates are reduced by the enhancements. One technique is based on selecting the originating carrier if capacity is available on that carrier. Availability of resources on other sections is also considered in selecting a carrier frequency, as is which carriers are data-filled with the same priority when carrier priorities are considered. Consideration is also given to possible alternative band carriers if in-band carriers do not have adequate capacity.

Abstract: A method for allowing a mobile station to find a code transmitted by a base station which has a propagation delay to the mobile station which is much larger or smaller than a propagation delay between the mobile station and a base station from which it derived a time reference is provided. In the context of IS-95, a PN offset is sent to the mobile station to identify which target base station pilot signals to search for. By sending a virtual PN offset which differs from the real PN offset, the mobile station can find the target base station signals where normally they would fall outside the mobile station's search window.

Abstract: In a switching platform of a telecommunications system, fault testing is automatically performed during operation of the switching platform to identify components to be tested, perform testing and if a fail condition occures, perform localization to isolate a source of the fail condition. In another mode of testing, an off-line component is identified and the test procedure automatically performs testing and if a fail condition occurs, a localization procedure is automatically initiated to identify a source of the fail condition. A configuration database containing status information on components of the switching platform can be periodically searched by the fault test procedure to identify components to be tested. The configuration database can also be searched to identify replacement components in response to an alarm identifying a faulty component generated by the fault test procedure.
