摘要： A facility is provided for establishing a relatively low-speed path from a user desiring to access the well-known Internet and establishing a high-speed path from the Internet to the user so that the data speed accommodates both the user's requests and a response from an Internet web/host site. Moreover, a user may be mobile, in which case the low-speed path is a conventional wireless path. In most cases, a predetermined spectrum of frequencies, such as one or more television channels, is used as the high-speed path from Internet.

摘要： The present invention is a restoration scheme for an ad-hoc ATM LAN wherein ATM cells are transported over a wireless point-to-point link. A method for restoring communications in the ATM network includes the steps of: generating a failure message indicative of a failure of a network element, the failure message including an identification of said network element and a predetermined VPI/VCI reserved for failure reporting; communicating the failure message to all said switching nodes in said network; and referencing updated routing tables at said switching nodes, wherein said network element indicated in said failure message is eliminated from routes in said network. Each of the switching nodes is included in a network tree spanning all said switching nodes in the network, wherein each of the switching nodes is included as a root in a specific network tree, each said network tree having a tree identification, the failure message further including a tree identification field containing the tree identification. The method also includes the step of routing the failure message in the switching nodes of the network based on the tree identification. The failure message includes a time stamp indicative of the time said failure message was generated, and the referencing of the updated routing tables is delayed a predetermined time period from the time of said time stamp before referencing said updated routing tables.

摘要： A system and method for routing ATM cells in a wireless ATM local area network (LAN) that use portable base station (PBS) switching nodes. Routing of cells to and from mobile users within the network is accomplished utilizing a novel routing scheme which preserves cell sequence. Each user transmitting data to another user is associated with a Source Home Station or node and each user receiving data is associated with a Destination Home Station or node. When a connection is established in the network between a first mobile user and a second mobile user, the ATM cells are routed along a fixed path from the first mobile user to the associated Source Home Station and along a fixed path between the Source Home Station to the Destination Home Station and then along a fixed path from the Destination Home Station to the second destination user. In this way cell sequence is maintain by utilizing the Source Home to Destination Home path. Mobile users within the network are also associated with a Local PBS which can be different from the Home Stations as the mobile moves around the network. The Local PBSs associated with the mobile user are slowly updated to be the Home Stations to cure inefficient routing.
摘要翻译：一种用于在使用便携式基站（PBS）交换节点的无线ATM局域网（LAN）中路由ATM信元的系统和方法。利用保留小区序列的新颖的路由方案来实现到网络内移动用户的移动用户的路由。向另一用户发送数据的每个用户与源家庭站或节点相关联，并且每个接收数据的用户与目的地家庭站或节点相关联。当在第一移动用户和第二移动用户之间的网络中建立连接时，ATM信元沿着固定路径从第一移动用户路由到相关联的源家庭站，并沿着源家庭站之间的固定路径路由到目的地家庭站，然后沿着从目的地家庭站到第二目的地用户的固定路径。以这种方式，通过利用源归属到目的地归属路径来维护信元序列。网络中的移动用户也与本地PBS相关联，本地PBS可以随着移动网络周围移动而与家庭站不同。与移动用户相关联的本地PBS被缓慢更新为家庭站，以治愈低效路由。

摘要： A wireless services data network supporting the mobility of an Internet Protocol (IP) over ATM networks is implemented such that a joint ATM-layer hand-off and MAC-layer hand-off are respectively used to handle in-session and inter-session mobility. In this way the effect of mobility is localized and transparent to higher-layer protocols. Also, different functions, including the so-called Address Resolution protocol, location of a mobile, and ATM connection, are combined to reduce front-end delay for connectionless packet transmissions in connection-oriented ATM networks.
