Transient Control Solution For Optical Networks
US Patent:
7444078, Oct 28, 2008
Filed:
Mar 17, 2004
Appl. No.:
10/803062
Inventors:
Joseph T. Stango - Manalapan NJ, US
Guodong Zhang - Manalapan NJ, US
Guodong Zhang - Manalapan NJ, US
Assignee:
AT&T Intellectual Property II, L.P. - Reno NV
International Classification:
H04J 14/02
US Classification:
398 79, 398 18, 398 83, 398 92, 398 97, 398173, 398177, 359334, 35933713
Abstract:
An optically amplified wavelength division multiplexing network has the functionality to add/drop channels at the optical add/drop multiplexing (OADM) nodes. The OADM node includes a receiver amplifier, an OADM module, and a transmitter amplifier. Once the OADM node detects a loss of signal (LOS) due to a fiber cut or network element failure upstream, the receiver amplifier is kept in operation as a noise source. The output of the receiver amplifier is immediately raised by increasing pump power to compensate for the LOS. The noise power received at the transmitter amplifier from the receiver amplifier is substantially equal to the signal power expected before LOS. The transient effect of downstream optical amplifiers is therefore completely suppressed and the inter-channel stimulated Raman scattering (SRS) induced spectrum tilt does not change. After the noise power is raised, the receiver amplifier may be shut down at a speed much slower than the speed of downstream amplifier control circuitry.

Method And Apparatus For Signaling The Release Of A Persistent Resource
US Patent:
2013005, Mar 7, 2013
Filed:
Mar 2, 2012
Appl. No.:

Assignee:
INTERDIGITAL PATENT HOLDINGS, INC. - Wilmington DE
International Classification:
H04W 72/04
US Classification:
370329
Abstract:
A method and apparatus for signaling the release of a persistent resource in long term evolution (LTE) are disclosed. An indication of the release of a downlink (DL) persistent resource is received by a wireless transmit receive unit (WTRU) from an evolved Node-B (eNB) via a physical downlink control channel (PDCCH). A positive acknowledgement (ACK) is transmitted by the WTRU which denotes that the indication has been received. The PDCCH or a medium access control (MAC) CE may be used by the eNB to signal the indication. At least one bit may be added to contents of the PDCCH to signal whether the PDCCH is for DL persistent or dynamic resource allocation. The DL persistent resource is then released and an indication that the DL persistent resource has been released is transmitted.
