摘要:
A network-on-chip router which includes an input buffer, an input controller connected to said input buffer, an arbiter connected to said input controller, a crossbar connected to said arbiter and said input buffer, and an output buffer connected to said crossbar. The network-on-chip router minimizes propagation time of data through the router by ensuring that the propagation delay of data through an input buffer is less than the combined propagation delay of data through an input controller and arbiter.

Unique temporary MAC addresses are calculated by mobile devices connected to wireless networks, using access point advertising information in combination with the permanent MAC address of the mobile device. The mobile devices use a hash function to construct a bit sequence from which a temporary MAC address can be extracted. The MAC address is unique over the entire region in which the mobile device can operate, without necessity of any coordination or negotiation between various access points of the region.

The preferred embodiments provide a novel system and method for reducing authentication delay of a mobile node with a network that includes: employing two EAP runs concurrently to reduce an overall authentication delay. In some embodiments, the two EAP runs are employed for authenticating a particular device identifier of a PaC. In some illustrative embodiments, the two EAP runs are employed for authenticating a particular device identifier of a PaC in relation to connecting to multiple ISPs at the same time.

This document describes, e.g., a system and method for minimizing superfluous signaling traffic and for minimizing data processing pressures on a network including a network information repository (NIR), comprising: having mobile stations that enter a network domain compare and detect inconsistencies in network information received through different sources and report those inconsistenci to the NIR; having the NIR update a cell broadcast controller (CBC)/BMSC with said network information; and having the CBC/BMSC broadcast or multicast the updated information.

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 application sets forth, among other things, a new approach for real time collection, discovery, and sharing of network and user information, which we refer to as Autonomous Collaborative Information Collection, Discovery, and Sharing (AC-CDS). It is autonomous because regular mobile users and devices act autonomously to collect information and make the information available to others. It is collaborative as the autonomous actions of the mobile users and devices help each other to discover the information they want.

The present application describes, inter alia, novel techniques to perform pre-evaluations of multiple Wi-Fi Access Points (AP) and Access Networks (AN). A pre-evaluation determines whether or not an AP is connected to the Internet and measures the path performance that the AN, via that particular AP, can offer between the mobile device and a pre-specified Internet host. In addition, the invention also discloses methods to determine whether the AN requires a user to actively authenticate themselves through a redirect log-on page.
摘要:
Data packets are transmitted from a first access network to a first interface of a multiple interface device (MID), and identical data packets are transmitted concurrently from a second access network to a second interface of the MID. Some of the data packets that are transmitted to the MID from the first access network are not received by the first interface. The MID inspects identifiers of data packets from the first and second interfaces in order to send to the application a stream including all of the data packets. For example, the MID sends to the application the data packets from the first interface, buffers the data packets from the second interface, and sends data packets from the buffer to the application upon detecting that data packets in the buffer were transmitted to the first interface but not received by the first interface.
摘要:
A system and method for assigning channel access is described. At least one of a terminal or an access point transmits a message to other entities where the message assigns access to an assignee and includes a duration field of a specified length. The unassigned terminals or access point remain silent for a duration specified in the duration field while the assignee has access to the channel.
