  • SYSTEM AND METHOD FOR COMMUNICATION SESSION CORRELATION
    Publication number: 20140059240
    Abstract: A system and method for correlating communication sessions. A globally unique correlation identifier is created and exchanged between the parties during Session Initiation Protocol (SIP) session setup to allow for association and correlation of additional SIP sessions between the same parties or with additional parties. The correlation information may then be used by network and session entities to perform different services.

  • System and method for communication session correlation
    Patent number: 8625602
    Abstract: An arrangement and method in a communication system such as an Orthogonal Frequency Division Multiplexing (OFDM) radio receiver for reducing the impact of interference from an intermittent interfering signal transmitted by an interfering system which may be co-located with the OFDM system or may be remotely located. Each OFDM symbol in a received OFDM signal includes a guard interval (GI), a middle portion, and a last portion identical to the GI. The arrangement determines which portion of each OFDM symbol is contemporaneous with the interfering signal and time-shifts a fast Fourier transform (FFT) window in the OFDM receiver to minimize or eliminate FFT processing of samples of the OFDM symbol that are contemporaneous with the interfering signal, thereby minimizing the impact of the interfering signal.

  • Adaptation of push mail filters to save UE battery power
    Patent number: 7561901
    Abstract: One or more push mail filters of an email dispatcher is automatically, and preferably in an event-driven and dynamic manner, adapted to decrease the number of messages transmitted to a battery-operated user equipment (UE) based on one or more battery conservation parameters monitored by or for the UE.
