| Number | Title | Issue Date |
| 7136624 | Radio resources allocating method, radio resources allocating apparatus, and mobile communication system An object is to select destination mobile stations so as to prevent directional beams directed to the respective mobile stations from interfering with each other in application of a directional antenna, and to allocate the radio resources to the mobile stations thus... | 11/14/2006 |
| 7065324 | Controlling performance measurements in a telecommunications network A network management system, for example for use in a telecommunications network, includes a performance measurement tool for carrying out one or more performance measurements relating to physical or logical components of the network. A performance management contro... | 06/20/2006 |
| 6898214 | Technique for monitoring SONET signal A technique for performance-monitoring of a standard SONET signal involves first converting the optical signal to an electrical signal, removing in the framing signal time slot the framing signal for leaving only the framing signal noise in such time slot, and separ... | 05/24/2005 |
| 6795881 | Physical layer and data link interface with ethernet pre-negotiation A word-based interface between a MAC and a PHY, allowing for variable pin counts, variable PHY and MAC data speeds, and variable numbers of connected PHYs. The word-based interface allows for the PHY to provide PHY-to-MAC words to the MAC, and for the MAC to provide... | 09/21/2004 |
| 6690649 | QoS management apparatus A QoS management apparatus in which the quality of the requested QoS for each path and different values of the state are managed. A QoS monitor, a registered QoS, and an operation determining function are provided for each path, and the QoS is precisely m... | 02/10/2004 |
| 6611231 | Wireless packet switched communication systems and networks using adaptively steered antenna arrays Methods, apparatuses and systems are provided for use in a wireless routing network. One apparatus, for example, includes an adaptive antenna that is configurable to receive a transmission signal from a transmitter and in response transmit corresponding o... | 08/26/2003 |
