    • 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.
    • 本文档描述了免费IP(TIP),一种商业模式及其通过基于IP的接入网络(例如,基于IEEE的公共无线热点网络)提供免费到用户(“免费”)连接的启用方法 802.11),其可以由不同的网络运营商操作。 通过TIP,使用网络与免费IP目的地通信将由免费IP目的地的所有者支付。 可以通过许多方式来识别免费的IP目的地,例如通过免费IP地址,免费因特网域名,免费通用资源标识符或通用资源定位器。 TIP使用户能够使用网络,而不需要网络或服务提供商进行先前的服务订阅,并且没有任何特殊的终端软件或硬件来获得使用网络的权限。 它允许用户使用比任何单独的网络运营商或聚合器可以提供的更多的接入网络,即更大的“足迹”。 通过TIP,服务提供商可以通过基于IP的接入网络提供服务,而无需与每个单独的网络运营商或聚合器进行业务安排。 TIP还可用于启用其他增值服务,如预付费IP,收集IP,选择性收费以及跨多个运营商或聚合商的接入网络以及甚至跨无线LAN(例如,公共热点和企业无线局域网)的单个预付帐户 )和蜂窝网络。

    • Method, system, and circuitry for successfully completing soft handoff in an Internet Protocol (IP) based autonomous base station wireless Code Division Multiple Access network, wherein processing is done at the serving base station so that target base stations need only set up the channel for transmitting the copied data needed for soft handoff. Concomitant circuitry comprises packet data multiplexers/assemblers and demultiplexers/de-assemblers for performing cross-layer switching. Data packets are sent by a serving base station to a mobile unit while the mobile is in a soft handoff region. The serving base station also sends copies of the data packets to target base stations, the target base stations in turn relay these data packets to the mobile. The mobile synchronizes the copies of the data packets received and combines the packets to recover the data.
