摘要： A message scheduler uses two thresholds to place cells into a queue. One determines, for a non-full queue, where to place high-delay-priority cells in relationship to low-delay-priority cells, and the other determines, for a fall queue, which low loss-priority cells to push out to make room for a high-loss-priority cell.

摘要： A method and system are disclosed for constructing a power spectrum based connection admission control table and using such a table in a communications network, such as an ATM network. Power spectrum parameters, such as the power spectrum DC component .gamma., half power bandwidth B.sub.w and average power .PSI..sub.w are transformed to .gamma., an equivalent half power bandwidth B.sub.e and an equivalent average power .PSI..sub.e, where B.sub.e is a predetermined constant. Since B.sub.e is constant, the transformation reduces the memory requirements for constructing a connection admission control table.

摘要： An exclusive VCC is maintained between each two communicating work stations (MT pair). The handoff method differs if the MT moves to a coverage area having a base station connected to the same switch as the previous coverage area (intra-switch mobility) or to a coverage area having a base station connected to a different switch than the previous coverage area (inter-switch mobility). In intra-switch mobility, the switch changes the path directly to the new base station and eliminates the path through the original base station. In inter-switch mobility, the switch performs the path set-up. The path may be elongated from the switch connected to the original BS, to the new BS, rather than from the original BS to the new BS. This eliminates the path through the original base station. The exclusive VCC between the MT pair permits path elongation to be minimized.
摘要翻译：在两个通信工作站（MT对）之间维持独占VCC。如果MT移动到具有连接到与先前的覆盖区域（交换机内移动性）相同的交换机的基站的覆盖区域或者具有连接到与先前覆盖的不同交换机的基站的覆盖区域的切换方法不同区域（交换机间移动性）。在交换机内的移动性中，交换机将路径直接改变到新的基站，并消除通过原始基站的路径。在交换机间的移动性中，交换机执行路径设置。该路径可以从连接到原始BS的交换机延伸到新的BS，而不是从原始BS到新的BS。这消除了通过原始基站的路径。 MT对之间的专用VCC允许路径伸长率最小化。

摘要： A system and process are provided for controlling congestion at a node of an asynchronous transfer mode (ATM) communications network. The process and system utilize fuzzy logic in determining whether or not to "admit," i.e., allocate a virtual channel (VC) for, new communications (or calls) to the node. Fuzzy logic is also use to control the rate cells are transmitted to the node for communications already "admitted," i.e., for which a VC has already been allocated. The fuzzy logic rules for bandwidth estimation in admission control may be developed from an "equivalent capacity" model. The fuzzy logic rules for adjusting cell transmission rates may be developed from a "two-threshold" congestion control model.
