摘要:
A Virtual Soft-Hand-off method for wireless IP-centric CDMA networks whose routers, hosts, and mobile stations have small group multicast (SGM) capability comprises setting up an explicit synchronous multicast session among a small group of participants with dynamic group membership. Packets transmitted over the multicast session are time stamped to help maintain synchronization, and the receivers recover multiple packet flows from the multiple received signals concurrently and combine them to create a single packet flow at higher layers.

The present application discloses, inter alia, a system for improving the aggregate throughput of a wireless local area network which includes: at least one access point that is equipped with at least one transceiver configured to simultaneously transmit and receive at multiple frequencies using multiple channels; and the access point being configured to acquire channel conditions of users and to pool sets of users on the channels based on the channel conditions.

A system and method for equalizing traffic between antenna beams is described. Aspects of the system and method may vary the beam widths to attempt to equalize traffic based on non-real-time communications and/or non-real-time communications.

摘要:
In a network of devices having a plurality of local domains, each local domain is likely to comprise a plurality of networks or communities of devices that communicate using a shared native protocol such as Jini, UPnP, Bluetooth, HAVi, WiFi, WiMAX or other standard architectures and protocols. The Open Services Gateway initiative (OSGi) created a platform and method for various networks to communicate with one another in a local domain. OSGi does not, however, solve the problems associated with communication across local domains. An instant messaging protocol such as Session Initiation Protocol (SIP) and a remote services register are used to provide a means for communication between local devices in a plurality of local OSGi domains using native communications protocols.
摘要:
Methods for coordinating power usage and link adaptation in wireless communications are described. Terminals and/or access points (APs) may attempt to modify terminals' transmit power in relation to a desired communication data transfer rate. Link adoption may also be used in conjunction with the described methods.

A system and method for processing commentary that is related to content is provided. In an illustrative embodiment, the system and method involves receiving commentary that is related to content and which is generated after generation of the content, and generating data associating the commentary with the content by at least one of spatially linking the commentary to the content or temporally linking the commentary to the content.
摘要:
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.
