IPC: H04B10/291
Filed: 2004-03-12
Abstract: An economical optical network is constituted by effectively using network resources by using the minimum number of, or minimum capacity of 3R repeaters.    section information corresponding to topology information on the optical network to which an optical node device itself belongs is stored, and the 3R section information stored is referred so as to autonomously determine whether or not the optical node device itself is an optical node device for implementing the 3R relay when setting an optical path passing through the optical node device itself. Alternatively, when the optical node device itself is a source node, another optical node device for implementing the 3R relay among the other optical node devices through which the optical path from the optical node device itself to the destination node passes is identified, and this identified optical node device is requested to implement the 3R relay when setting an optical path in which the optical node device itself is a source node.

Title: Managing searcher and tracker resources in a wireless communication device
Inventor: SALAMAN GLENN
IPC: H04B7/216
Filed: 2003-12-17
Abstract: A Wireless Communication Device (WCD) includes multiple fingers that track one or more tracked transponder beams. Each tracked beam is from a respective tracked transponder. The WCD determines a tracked-beam searcher energy for each of the tracked beams, and an untracked-beam searcher energy for each of one or more untracked beams from each of the tracked transponders. The WCD  attempts to determine a preferred one of the untracked beams that should become a tracked beam. This determination is made based on the tracked-beam and the untracked-beam searcher energies. The WCD assigns, or alternatively, reassigns, a finger to the preferred untracked beam when the attempt to determine a preferred untracked beam is successful. The transponders may be satellites or base stations.
