Abstract: The alternate destination redirection (ADR) feature (102) of telephone switching systems (101) or an equivalent is used to implement a "post-route" routing architecture having the benefits of a "pre-route" routing architecture in a network ACD. The ADR feature is administered in the network (100) for individual ACD systems and individual call types at each ACD system to identify another ACD system as an alternative destination for calls of the individual call type rejected by the individual ACD system. The network distributes calls to the plurality of ACD systems (110-112) on a basis (e.g., fixed percentage, round-robin) that does not require the network to know the status of the individual ACD systems. Upon having a call of an individual type routed thereto, an individual ACD system checks the status of the ACD system that is administered as the alternative destination for its rejected calls of the individual type. If it determines that it can provide the better service, the individual ACD system services the call. If it determines that the alternative destination ACD system can provide the better service, the individual ACD system rejects the call, whereupon the network, operating under influence of the ADR feature, releases the connection of the call to the individual ACD system and reroutes the call to the alternative destination ACD system.

Abstract: An advantageous scheduling template slot ordering for use in establishing a scheduling order of events such as transmitting communication signals in a communication network is determined by assigning at least two initial slot positions to a particular signal class and then determining a regularity mea surebased on a lower bound for the regularity measure of such assignments and the remaining unassigned slot positions. This lower bound for the regularity measure of the unassigned slots is advantageously based on a hypothetical assignment of fractions of the slot positions to different signal classes in stead of limiting the assignment of a slot to a single signal class. This fractional slotassignment produces a regularity measure that is bet ter than or equal to a corresponding regularity measure based on assigning a whole slot to a partic ularsignal class. The lower bound of the regularity meas ure is then compared with a threshold regularity measure, such as from a known reference scheduling template. If the threshold regularity measure is lower than the determined lower bound, then it is known that the reference template would provide a mo re desirable regularity of events than any template having the assigned slot positions to that particular signal class. As a consequence, other slot assignments canbe compared to the reference template to rapidly identify scheduling templates with enhanced regularity characteristics.

Abstract: 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 priorit izing a selected subset of the prioritized channel list. In further enhancements of the prese nt invention, prioritizing a channel list is distributed on a per cell/sector basis so tha t prioritization is independent of frequency usage information from other cells/sectors and prio ritization is based upon uplink and downlink characteristics.

Abstract: An advantageous measurement technique evalutes theoverall scheduling regularity producible by a scheduling template having particular slot assignment orderings for respective classes of events such as, for example, transmitting order of communication signals over respective virtual circuits by a node of a network. This measurement technique is used for measuring the overall scheduling regularity producible by each of a plurality of different scheduling templates to select the template having a desirable regularity measure for use in establishing a scheduling order of events for a network.
