  • Patent number: 8625527
    Abstract: A method and a system for maintaining session continuity, in which the system includes a Handover Source Function (HOSF), a Handover Destination Function (HODF), a Handover Anchor Function-Control Plane (HOAF-CP) and a Handover Anchor Function-User Plane (HOAF-UP). The method includes a first user establishing a connection through the HOSF with the HOAF-CP and the HOAF-UP which correspond to a second user, so as to establish a session with the second user. The method further includes that, during session handover, the HODF that corresponds to the HOSF establishing another connection with the HOAF-CP and HOAF-UP though which the first user continues the session with the second user, so as to maintain the session continuity. When access address or access technology of the terminal changes, or even the terminal changes during a session, the method and the system can logically replace the connection before the handover with a new connection to ensure the session continuity.

  • Publication number: 20140003248
    Abstract: Systems, methods, and devices for bearer independent protocol gateway performance optimization are described. In one aspect, a bearer independent protocol gateway is provided in the device which includes a traffic analyzer configured to detect when HTTP transaction(s) (request and corresponding responses) is/are completed and to switch to the next socket as soon as the transaction is completed, without necessarily waiting for the TCP socket to be closed. For example, when the gateway detects that the response is complete, it may push the current socket back into a socket queue and start serving the next socket.

  • Publication number: 20140003817
    Abstract: A Multiple-Input-Multiple-Output (MIMO) data transmit-receive protocol that can be used with an arbitrary light array, including one or more lights, that transmits light to a light receiver having an image sensor, including a large number of light sensing pixels. The protocol supports two primary protocol or coding modes in which the light array may transmit: spatial coding and space-time coding. The protocol is constructed upon the use of efficient start-frame-delimiters (SFDs) and data-delimiters (DDs). The lights may be implemented to transmit the SFDs, the data delimiters, and data bits as modulated light. The light may be modulated in accordance with a modulation technique referred to as frequency shift on-off keying (FSOOK).

  • Publication number: 20140003240
    Abstract: Technology is discussed for supporting wireless communication paths from an antenna array with a vertical directional component. Examples reduce training feedback for increased numbers of communication paths by only reporting on a subset of Reference Signals (RSs) provided for various vertical beam configurations. Additional examples reduce feedback with virtual measurements based on a difference between RS measurements. One such measurement can come from full set of RSs for a reference beam configuration and another from a partial set of RSs for an additional beam configuration. Such virtual measurements can also be based on cross correlation for beamforming weights associated with the two configurations. Several examples of preparing and sending measurement reports consistent with Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards are discussed.
