    摘要： A method and system for dynamic forward assignment of IP addresses in a wireless network wherein a serving base station requests IP addresses of it neighboring cells. The serving base station then provides the requested IP addresses to the mobile stations it serves based on whether the mobile station will be entering a particular neighboring cell. Immediately upon entering the neighboring cell the mobile station establishes over the air communications with the neighboring cell's base station using one of the requested addresses. In another embodiment of the present invention each mobile unit is responsible for attaining IP addresses from the base stations of neighboring cells. Accordingly, the base stations serve as relay points for the IP address requests from the mobile unit to an address server.

    摘要： A Multi-Interface Mobility Management (MIMM) client is provided on a mobile Multi-Interface Device (MID) to support seamless network connectivity and switching of the MID. The MIMM client communicates with a MIMM Server. The MIMM Server collects information from MIMM Clients and provides information to the MIMM Clients pertaining to the network(s) to which the mobile MID has access, such as information concerning the availability of a network, the quality of network connectivity, etc. The MIMM Client is responsible for determining whether and when a handoff or roaming operation should be initiated by the mobile MID, and which network interface the mobile MID should use after the handoff/roam operation has been completed. The MIMM Client also is responsible for performing mobility-related functions that are required prior and subsequent to the handoff/roam operation. The MIMM Client uses the information received from the MIMM Server in order to make these determinations.

    摘要： This document describes Toll Free IP (TIP), a business model and its enabling methods to provide no-charge-to-user (“toll-free”) connectivity through IP-based access networks (e.g., public wireless hotspot networks based on IEEE 802.11), which may be operated by different network operators. With TIP, the use of networks to communicate with a toll-free IP destination will be paid by the owner of the toll-free IP destination. A toll-free IP destination can be identified in many ways, e.g., by a toll-free IP address, toll-free Internet Domain Name, a toll-free Universal Resource Identifier or Universal Resource Locator. TIP enables a user to use networks without prior service subscriptions with network or service providers and without any special terminal software or hardware for gaining permission to use a network. It allows users to use more access networks, i.e., larger “footprints”, than any individual network operator or aggregator can provide. With TIP, a service provider can provide services over IP-based access networks without the need to have business arrangements with each individual network operator or aggregator. TIP can also be used to enable other value-added services such as Prepaid IP, Collect IP, Selective Charging, and a single prepaid account across access networks of multiple operators or aggregators and even across wireless LANs (e.g., public hotspots and enterprise wireless LANs) and cellular networks.

    摘要： This Surface Acoustic Wave (SAW) filter has a tilted, interdigital transducer and a normal interdigital transducer separated from each other on a piezoelectric substrate. An input signal with a large bandwidth is applied to the tilted transducer, while an output signal is obtained from the normal transducer. Guaranteed attenuation can be greatly improved, and ripple in the pass band markedly reduced, by grounding one of the electrodes of the tilted transducer. This electrode is the one containing the longer of the two electrode fingers closest to the normal transducer.
