  • Device and method for selecting a visited network
    Patent number: 9967806
    Abstract: Device located in a mobile telephony infrastructure, that is capable of selecting a visited network and/or a host network, and of connecting a mobile terminal to said visited network selected via said selected host network, wherein said device is located in said mobile terminal, and wherein the selection is dynamically carried out through a sequencing according to at least one criterion.

  • Transmission system and method for equalization of channels in the system
    Patent number: 7123834
    Abstract: The invention is related to a method for equalizing performance of traffic channels in a WDM system where means for controlling transmitters (12), amplifiers (38) and receivers (14) are provided. Potentially, a number of channels are defined as loading channels (100). The method follows the steps of measuring the optical power at the input (48) of the amplifier (38), setting the power levels of a predefined number of loading channels (100) to a high power level, setting the power level of the traffic channels (200) to a power level less then the power level of the loading channels (100), adjusting the power level of the traffic channels (200), adjusting the power level of the loading channels (100), stabilizing the sum of the optical power measured at the optical amplifier (38), continuing the process for each channel the receiver lock signal (75) is sent back to the transmitters.
