摘要： Disclosed is a system utilizing a multi-beam antenna that switches the beams to a CDMA demodulation receiver in such a way that the best beams are selected. The transmit path takes the traffic channel outputs from the CDMA modulators and maps each traffic channel to the subset of beams that have the best path to the mobile in the forward link. Accordingly, the system operates to reduce interference on both the forward and reverse links, as well as to increase the capacity of both the forward and reverse links. The system also is capable of providing flexible dynamic shaping of the cell and the sectors by mapping the appropriate overhead channels on the forward link and the reverse link in different combinations of beams to sectors in order to shape the cell. Adaptive arrays may be utilized to form radiation patterns, for which the azimuthal width and/or length of a sector may be adjusted by way of adjustments of the relative amplitude and phase of signal components of signals at antennas of a phased array adaptively controlled according to communication parameters such as information indicating the quality of the communication channel on that sector, interference from other channels or the number of calls serviced in particular sectors.

摘要： The invention discloses a system and method which quantifies the traffic or load on a particular sector of a mobile communication cell site. The traffic quantification or load metric is preferably used to compare the load of each of the cell site's sectors. When the difference between load among the sectors reaches a certain level, the preferred embodiment of the present invention causes the sectorization of the site to change in order to alleviate or equalize the traffic load of the sectors. The system of the present invention continues to monitor the cell site for traffic conditions and for changes in the load responsive to the sectorization changes made in order to dynamically respond to the changing traffic conditions on the cell site.

摘要： A communication network is dynamically optimized using network operation metrics, such as may be acquired from a network controller such as a mobile switching center, to achieve network performance goals. Operational parameter adjustments, associated with a particular network resource and corresponding network resources, are preferably determined as a function of the network operation metrics. Implementation of the parameter adjustments are modeled to determine if further or different operational parameter adjustments should be determined. Preferably, actual implementation of the parameter adjustments is effected in part through providing the adjusted parameters to the network controller. Additionally or alternatively, the adjusted parameters may be provided directly to one or more network resources for implementation.

摘要： A system and method are disclosed for dynamically sizing sectors of a multi-sectored radiation pattern. The disclosed invention teaches the use of multiple narrow beams composited to form a radiation pattern. Signals associated with each such narrow beam may be provided to inputs of a scan receiver or signaling radio which inputs are associated with a particular sector of the radiation pattern. The number of narrow beam signals provided inputs associated with a particular sector defines the azimuthal width of that sector. By altering the number of narrow beam signals provided each such input, the azimuthal width of the sectors may be adjusted. The disclosed invention also teaches the use of attenuators in the signal path between the narrow beams and the scan receiver or signalling radio. By adjusting these attenuators, the effective length of the sectors may be adjusted.

摘要： A system and method are disclosed for avoiding nulls in a composite radiation pattern synthesized from a plurality of antenna beams. The disclosed invention teaches the use of delays in the signal paths associated with ones of the antenna beams utilized to synthesize the desired radiation pattern in order to avoid destructive combining of the signals. In a preferred embodiment delays are introduced in each antenna beam signal having a common attribute such as a common phase center. Accordingly, a minimum number of phase differential boundaries are introduced in order that certain communications, such as CDMA, are not adversely affected.
