A mobile station having a Voice-Over-Internet-Protocol client sends a message proposing a frame packing and frame repeating parameter set (). The called client may either accept the proposal or offer a revision (). If accepted the VoIP call is established (). If a revised proposal is received, it is determined whether the parameters are acceptable (). If not the call is declined (). If acceptable the call may proceed (). Both clients may then monitor network conditions () and propose revisions to the parameters as conditions change. In this way, the VoIP application layer compensates for physical and Medium Access Control (MAC) layer inefficiencies in transporting the small frames used for audio data transfer for VoIP.

Apparatus and method for end-to-end adaptive frame packing and redundancy in a heterogeneous network environment

In some of the preferred embodiments, a method for network discovery of a mobile device to use at least one of a plurality of access networks within an IP network includes: obtaining specified network information in the vicinity of a given location based on a set of criteria when a mobile is connected to the IP network from any location.

Network discovery mechanisms

In some embodiments, a system and method for substantially real-time comparison of quality of interfaces by mobile devices over heterogeneous networks is disclosed. The method can be performed using a dynamic and rapid comparison by distributed hosts, using a minimal number of injected network packets, using minimal path quality metrics, which path quality metrics are independent of how a Qol is measured, and in a manner suitable for both wireline and wireless networks.

Real-time comparison of quality of interfaces

Systems and methods are described for secure and seamless roaming between internal and external networks. Double and triple tunnels may be used to connect a mobile node to a correspondent host. A mobile node may include the ability to connect to two networks simultaneously to enable seamless roaming between networks.

Secure and seamless WAN-LAN roaming

Disclosed are methods and devices for a social networking device. The methods include calculating a value for a social networking indexfor contacts in a contact list, and prioritizing a subset of contacts. IP addresses of contacts retrievedfrom the Internet according to the social networking index can be preloadedfor the initiation of an IP based communication. The social networking index is generated from values of predetermined statisticsassociated with contacts of the contact list. The statistics associated with contacts of a contact list includea number of communications with a contact, a statistical value calculated from lengths of communications with a contact, a time since a last communication with a contact and a statistical value calculated from times between at least two consecutive communications with a contact. Calculating a social networking indexcan include applying weightswith which to combine the values of the predetermined statistics.

The present invention relates to the reduction of handoff delays for mobile telematics applications. In particular, the present invention provides a method employing GPS technology to define IP addresses in a mobile environment in order to reduce delays and transient data loss caused by handoff from one network to another.

Fast handoff using GPS technology for mobile telematics

A system and method for maximizing the standby time of mobile communication devices that have WiFi or other high energy-consuming network interfaces, by predicting in real time actionable silent periods (ASPs) of the interface and shutting the interface down during these ASPs. Standby times are significantly increased, resulting in longer periods of operation before battery charging is required, while keeping minimal the probabilities of missing incoming data packets when the interface is turned off.

Reducing power consumption of Wi-Fi enabled mobile devices

Sensors mounted on vehicles (e.g., buses, taxis, police cars) and public personnel (e.g., policemen) are used to monitor various conditions and situations such as air quality, potential biological and chemical attacks, and road and traffic conditions. The invention improves upon the typical approach that deploys fixed sensors at every geographical position of interest. The total number of required sensors and the size and the complexity of the network infrastructure required to connect the sensors are reduced and simplified. A method for estimating the number of mobile sensors required to cover a region of interest also is disclosed. A relatively small number of mobile sensors may be sufficient to cover a large area at a lower cost and less complexity than a fixed sensor network.

Environmental monitoring using mobile devices and network information server

In some embodiments, a system and method for substantially real-time comparison of quality of interfaces by mobile devices over heterogeneous networks is disclosed. The method can be performed using a dynamic and rapid comparison by distributed hosts, using a minimal number of injected network packets, using minimal path quality metrics, which path quality metrics are independent of how a QoI is measured, and in a manner suitable for both wireline and wireless networks.

Systems and methods for mobile peer-to-peer information sharing are disclosed. With the preferred systems and methods, mobile users and devices collect information about networks that they visit, and carry that information as they move to new networks. Mobile users and/or devices then share such information directly with each other.

Peer-to-peer network and user information discovery and sharing for mobile users and devices

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.

Method and systems for toll-free internet protocol communication services

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.
