Abstract: Methods and computer-readable media are provided to allow for the establishment of an Internet protocol (IP) data session with a dual-stack mobile communications device by authenticating the device. An IP data session is requested, and a home agent sends an indication of this request. A DNS server that will be assigned to a device is identified by querying a database and is identified based on the device's capabilities. The device capabilities are determined by a device-capability identifier that is associated with the user of the device or the device itself, such as a network access identifier. The capabilities may include the device type, applications, programs, or services that the user of the device is subscribed to, or capabilities that are inherent to the phone. Once the DNS server is identified, a server identifier is sent to the home agent, which assigns the DNS server to the device.

Abstract: Network services are provided to client devices based on the network traffic to be communicated between the device and the network. A number of home agents are configured to provide network services to mobile nodes. The system is configured in such a way that a mobile nodes may be served by more than one of the home agents. Thereby, for example, a certain mobile node may be provided one type of network traffic via one home agent and a different type of network traffic via another home agent.

Abstract: A method providing communication services to a mobile device is presented. In the method, a number of radio access networks are coupled with a packet data network by way of a number of access nodes. Each of a number of packet data flows between the mobile device and the packet data network are facilitated by way of the one of the radio access networks and one of the access nodes. State information regarding the packet data flows is exchanged between those of the access nodes facilitating at least one of the packet data flows so that each of those nodes possesses the state information for each of the packet data flows. One of the access nodes is then selected for facilitating one of the packet data flows based on the state information.

Abstract: A method for distributing a digital motion picture to multiple theaters in a region via terrestrial wireless communication. The motion picture is divided into chunks, and the chunks are transmitted to particular initial seed theaters in the region. To facilitate the initial seeding, downlink bandwidth on various wireless links is dynamically increased. Once the initial seeding is complete, the downlink bandwidth is decreased and is preferably equalized substantially with uplink bandwidth. The theaters in the region are then directed to begin peer-to-peer sharing of the chunks with each other, possibly through use of BitTorrent or other cooperative downloading process from the initial seed theaters. Ultimately, all of the theaters in the region thereby obtain all of the chunks of the motion picture and can conveniently present the motion picture to audiences.

The network element retrieves the user packet from the memory based on the memory pointer, processes the user packet with the second service function, and stores the user packet in the memory. The network element transfers the user packet.

A second block of packets is sent through the network at a second throughput rate. The second block of packets has the differential treatment field set to a second value. A first report indicating that the reception of the first block of packets satisfies a criteria is received. A second report indicating that the reception of the second block of packets satisfies the criteria is received. A treatment field value for the differential treatment field is selected based on the first report and the second report. A packet with the differential treatment field set to the treatment field value is sent to the network.

Abstract: A multi-stage, multi-pole connector provides improved connectivity with electronic devices having mating receptacles of differing form factors. In one aspect, the connector includes a hollow base plug portion, a hollow tip plug portion, and a series of conductive lines extending within the base plug portion and the tip plug portion. Both the base plug portion and the tip plug portion share the same longitudinal axis and are each formed with one or more discrete conductive contacts electrically isolated from one another. The tip plug portion extends axially from the base plug portion and has a smaller outside diameter along the length of the tip plug portion than the average outside diameter along the length of the base plug portion. This configuration causes the connector to step down in form factor to a smaller cross-sectional size moving from the base plug portion to the tip plug portion.

Abstract: Systems and methods are provided for an optimized mobile-IPv6 encapsulation. A mobile node sends packets to a correspondent node by encapsulating a packet using an IPv6 routing extension header, and reverse tunneling the packet to a home agent. The home agent modifies the packet and forwards it to the correspondent node. When the correspondent node sends packets to the mobile node's home address, the home agent intercepts the packet, encapsulates the packet with an IPv6 routing extension header, and tunnels the packet to the mobile node. Consequently, because packets are tunneled using IPv6 routing extension headers, the amount of overhead in each encapsulated packet is reduced, thus increasing the available bandwidth in a network.

Abstract: A universal receptacle facilitates improved connectivity between electronic devices through plug-type connectors within a range of form factors. In one aspect, the receptacle includes an elongate, open ended chamber, a series of conductive terminals disposed in the chamber, urging structure for urging the conductive terminals inwardly towards a longitudinal axis of the chamber, and a series of conductive lines electrically coupled with the conductive terminals. The conductive terminals may be located within the chamber such that the urging structure places the terminals in physical contact with the plug-type connector when the connector possesses a diameter that is less than the diameter of the chamber. In this way, the particular degree of displacement of the terminals varies depending on the form factor or diameter of a particular region of the connector, while electronic signal pathways are maintained between the conductive terminals of the receptacle and conductive contacts of the connector.

Abstract: A unitary connector system includes a single pin, multi-pole electrical connector having a plug body, as well as a mating receptacle. The plug body is formed of a series of discrete conductive contacts interposed with a series of insulative rings such that the insulative rings electrically isolate adjacent conductive contacts from one another, each contact thereby forming a terminal. A series of conductive lines extend within the plug body and are electrically coupled with the series of conductive contacts each representing a transmission channel. The universal nature of the plug body design allows for a specific number of poles to be chosen to handle the particular signal transmission requirements.
