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 system and method are provided by which a wireless network service provider is able to provide and maintain a high level of quality of service for terminals in the corresponding network, by overcoming problems that result in a diminished quality of service, including handoff delays as terminals move between cells in a network and the uncertainly as to which cell the individual terminals are moving to as they roam within the network. Providing and maintaining a high level of quality of service in a wireless network includes recording a history of movements of a terminal within the wireless network, analyzing the movements of the terminal within the wireless network to compute a probability distribution of the terminal's target location, and allocating network resources, including bandwidth and priority scheme, to the terminal based on the probability distribution for the terminal.

摘要： An arrangement including a scannable matrix for predicting the occurrence of a future collision of frequency hops of the channel hopping patterns on the respective activated first paths of a Bluetooth packet transmission system is described. A first coordinate of the matrix defines columns representative of a selectable window of N successive future time slots of the channel hopping patterns, and a second coordinate of the matrix defines rows each exhibiting the successive frequency hops of the patterns segments transmitted on a separate one of the activated channels during such window. The first coordinate is scanned to detect the occurrence, if any, of identical frequency hops appearing at an intersection of the then-scanned column and at least a pair of the rows. If a particular scan does not detect an occurrence of such identical frequency hops in any of the time slots of the scanned window, the first coordinate may be incremented by a selected number of time slots at the end of the scan, and the scan is then successively repeated for each new window that results. If and when identical frequency hops are detected in a particular future time slot during a scan, the channel hopping pattern(s) on a subset of the affected channels may be suitably altered to avoid the predicted collision.

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.
