摘要： Disclosed is a method for improving call quality and capacity by integrating a dynamic channel allocation technique into an intelligent antenna system. The intelligent antenna systems includes beams which are grouped into sets, wherein each set has associated a long list and a primary short list, and each beam has associated a secondary short list. In one embodiment, long term interference levels are measured on each beam in a set of beams for a plurality of communication channels to produce the long list; short term interference levels are measured on each beam in the set of beams for a portion of the plurality of communication channels to produce a plurality of secondary short lists and the primary short list; and communication channels are assigned to a mobile-station from the portion of the plurality of communication channels based on the measured short term interference levels on each beam in the set of beams. The long list and the primary short list are based upon highest measured long and short term interference levels, respectively, for each of the plurality of communication channels across each beam in the set of beams.

摘要： An interference based dynamic channel assignment scheme for a wireless communication network, for self configuring dynamic channel assignment of a plurality of channels, comprises the steps of: prioritizing a channel list and prioritizing a selected subset of the prioritized channel list. In further enhancements of the present invention, prioritizing a channel list is distributed on a per cell/sector basis so that prioritization is independent of frequency usage information from other cells/sectors and prioritization is based upon uplink and downlink characteristics.

摘要： A service establishes called party mailboxes (CPMB) for specified duration of time upon request of a calling party when a called party is unable or unwilling to respond to the calling party. The CPMB service permits a CPMB to be accessed by a called party and permits a CPMB to be modified by authorized users. The status of access information is available to the calling party which access information characterizes the extent of access to the established mailbox by the called party. The CPMB is advantageously implemented by a CPMB control system comprising a processor and memory which CPMB control system is connected to a communications network.

摘要： A method and apparatus for visually rendering a three dimensional structure as an image on a two dimensional display without specialized hardware. The invention renders each object of the structure one at a time on the display in descending order according to a measured distance, i.e., rear to front of the structure, of the object from a predetermined view point. As each object is rendered, depth relationships between the objects are conveyed to users. To reduce the number of computations required for rendering the objects, the present method and apparatus use a reference point to determine the measured distance from the predetermined view point to each object.

摘要： An efficient parallel event simulation method is implemented by simulating blocks of M edge events, where M is approximately equal to e logeN, and N being the number of interconnected processing elements. Following a simulation iteration, each processing element shares information with adjacent processing elements that relates to events that the processing elements simulated which may affect the simulation of events at the neighbor processing elements. When the communication reveals that the information that is shared by a neighbor processing elements is different from the information that the processing element assumed, then the arriving information is kept and the simulation process is repeated. In executing the repeated simulations of a block, the same random variable values are employed. When all of the processing elements find that the arriving shared information is the same as the information already known to the receiving processing element, simulation of the block ends. A new simulation floor is ascertained, and another block of event is simulated.
