  • Patent number: 8107444
    Abstract: An arrangement and method for channel mapping in a UTRA TDD HSDPA wireless communication system by applying interleaving functions in first (530) and second (540) interleaving means to a bit sequence to produce symbols for mapping to physical channels, the first and second interleaving means being arranged to map symbols from respectively systematic and parity bits in a predetermined scheme, e.g., mapping symbols in a forward direction when a channel has an even index number, and in a reverse direction when a channel has an odd index number. The symbols may comprise bit-pairs, each of a systematic bit and parity bit. Systematic bits are preferably mapped to high reliability bit positions in TDD HSDPA, achieving a performance gain of between 0.2 dB and 0.5 dB. The forwards/reverse mapping allows a degree of interleaving that improves system performance in fading channels or channels disturbed by short time period noise or interference.

  • Patent number: 8102989
    Abstract: Gateways facilitate communication of voice traffic from a calling party to a called party over a packet network. To establish a communication session, an originating gateway sends one or more initial call control messages using overlap signaling to a destination gateway. The destination gateway may be unable to establish the communication session using overlap signaling. The destination gateway signals the originating gateway, such as by indicating that the communication session could not be established because of an incomplete or invalid destination address. The originating gateway then attempts to establish the communication session using en bloc signaling. In this way, an attempt that fails due to the use of overlap signaling is retried using en bloc signaling.

  • Publication number: 20110176444
    Abstract: A transmission-time measurement section (201) and a jitter measurement section (202) measure transmission time length and jitter, respectively, by using the packets transmitted/received. A forward-error-correction (FEC)-scheme maximum-jitter measurement section (203) calculates a maximum jitter in the case of adopting an FEC scheme, and an automatic-retransmission-request (ARQ)-scheme maximum-jitter measurement section (204) calculates a maximum jitter in the case of adopting an ARQ scheme from the measured information. A packet control section (205) selects a communication scheme having a smaller maximum jitter from both schemes based on the calculation result of the FEC-maximum-jitter measurement section (203) and ARQ-maximum-jitter measurement section (204).
