According to some embodiments, a key management apparatus for deploying in a smart grid system adapted to receive metering data from smart meters connected to at least one relay via a network, includes: a key control mechanism that derives a key array of individual purpose specific keys from one master key such that the purpose specific key in the key array are each independent cryptographic keys for each specific usage in an application or for each application if there is only one specific usage in an application.

Key management device, system and method having a rekey mechanism

This present application relates to, among other things, novel techniques to evaluate and qualify multiple networking options. A device contains multiple network connectivity options, including but not limited to various wireless and wired technologies such as Wi-Fi, 3G, WiMAX, LTE, Ethernet, Bluetooth, UWB, WHDMI, etc. Each connectivity option can be evaluation and pre-qualified prior to the user selecting that mode of communication. This evaluation process takes into account both lower-layer information such as signal strength, bit error rates, SNR, interference, etc. but also network-layer information such as IP connectivity, and end-to-end path performance.

System and method for evaluating multiple connectivity options

A system and method for supporting mobile coalitions for entertainment comprises devices including a master device, a server having a multimedia service executable by the master device and modules operable to recommend formation of a coalition based on the service, invite the devices to participate in the coalition, set up the coalition by determining the devices to participate, launching on each device a link to the coalition, performing emulation of the coalition by streaming a portion of the service to each device until experience is satisfactory, and continuing by transmitting the service to the devices, capture interactions on the devices by users, the interactions comprising at least gestures, taps correlating to messages of quality of experience, adapt the coalition by managing user inputs conveying quality of experience, maintaining synchronization of the devices, and maintaining the service when one or more of the devices cease to participate, and terminate the coalition.

Method and system supporting mobile coalitions

A system and method for aggregating and fragmenting packets is described. Data packets containing voice data and other data that suffer significantly in quality when delayed may be aggregated together and fragmented. The aggregation and fragmentation permits networks to push these time-sensitive packets more easily through a network based on priority given to fragmented data.

Aggregation and fragmentation of multiplexed downlink packets

A packet data network gateway device may receive packet network data at a packet data network gateway device; filter the received packet network data to extract information associated with one or more messages in the packet network data; analyze the extracted information; and dynamically determine one or more of policy updates, rules, or thresholds based on the analyzing of the information and information associated with one or more of subscribers, location, existing policies, network operating condition and load.

Mobility policy updates for mobile devices

The preferred embodiments provide a system and/or method that exploits the presence of multiple interfaces to provide high quality video streaming (or real time streaming). The proposed solution includes three specific strategies 1) receiver buffer management, 2) selective re-transmission of packets and 3) dynamic load balancing across interfaces to achieve high quality video streaming across multiple interfaces.

Streaming video over multiple network interfaces

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.

Channel partitioning for wireless local area networks

A network element or server that manages name, address and identifying information of network devices that contain at least one Bluetooth interface is described. A Bluetooth Device Address may be queried by a first network device of a second network device to the server and the server may provide additional name, address and identifying information on the queried second network device to the first network device such that the first network device may establish a preferred connection with the second network device.

Management of communication among network devices having multiple interfaces

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.

Bridging local device communications across the wide area

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.

Terminal transmit power control with link adaptation

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.

Load equalizing antennas

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.

Pre-evaluation of multiple network access points

A system and method for improving quality of experience (QoE) of using a mobile device can comprise utilization of stored information relating to RANs of service providers and QoE ratings, receiving an event related to the RANs or to mobile Web browsing actions, receiving requests for QoE metrics based on the event, parsing and interpreting results of the QoE metrics; preparing and beginning an emulation session of the RANs, choosing a presentation style, rendering QoE in accordance with the browser actions and the presentation style which can be purely quantitative comparison, pre-recorded session, limited interaction-emulated session, live interactive session and live automatically controlled non-interactive session, and enabling user input according to the presentation style. The method can comprise standardizing information to allow comparison of the information, rendering network-related information on a display and updating the presentation of the network-related information to maintain a fair representation of the RANs being emulated.

Method and system to support user-centric selection of point of attachment through momentary interactive multimedia experience conveyance and through correlation of web links to quality and experience metrics

A terminal device includes multiple interfaces having links to various networks. When a trigger event occurs, the terminal device selects a target link to a network to transition from its current link. A candidate link selection function determines candidate links that are filtered to remove links not meeting connectivity criteria. A target link selection function is then executed to select a target link from the filtered candidate links. Thus, the target link selection function is not run for every possible link, but only those meeting the criteria.

Network selection mechanism

Embodiments of the present invention disclose a secure localization infrastructure using transmitters that can transmit messages at multiple distinct power levels throughout a community of reference points. Transmitters send messages at different power levels in a manner that every location in the system corresponds to a unique set of messages. Received messages are reported back to the localization infrastructure, which then determines location by comparing the messages reported.
