摘要： A cellular wireless communication system and method of operation manages Walsh codes in order to ensure that sufficient Walsh codes are available to prevent call blocking and to support additional hand-off operations. In an initial operating condition, the cellular wireless communication system services normal hand-off operations in which a maximum number of cells and sectors may participate in hand-off. With hand-off operations according to the present invention, each cell or sector participating in hand-off for a mobile terminal uses a unique Walsh code for covering its forward link signals. When the number of Walsh codes available for servicing new calls is reduced so that it meets or exceeds a Walsh code availability threshold, the number of cells and sectors that may participate in hand-off is reduced from the maximum number. In the number of participating cells/sectors results in release or non-use of some Walsh codes. In subsequent operations when sufficient Walsh codes are available for servicing hand-off operations, a greater number, up to the maximum number of cells and sectors may again participate in hand-off of the mobile terminal.

摘要： A refractory nozzle is provided for a metallurgical vessel, in particular for steel melts, wherein the nozzle has a flow-through opening with an upper end, a lower end, and an inner wall laterally enclosing the flow-through opening. In order to improve known discharge nozzles, in particular with regard to their thermal shock resistance, a heater and/or a thermal insulating material, that dissolves or bums upon contact with fluid steel, is arranged along the inner wall in the flow-through opening.

摘要： The present invention provides greater capacity in a dynamic allocation of power. First, the invention requires the reduction, not the increase, of signal power in low traffic areas. Because this signal power reduction reduces interference in surrounding high traffic cell site areas, those high traffic cell site areas can re-direct some of this surplus power to support a greater voice and data traffic load. Accordingly, the invention increases capacity of voice and data communications in high traffic areas, where it is needed most, by lowering (and dynamically regulating) the signal power in low traffic cell site areas.
摘要翻译：本发明在动力分配中提供更大的容量。首先，本发明要求减少而不是增加低交通区域的信号功率。由于这种信号功率降低降低了周围高流量小区站点区域的干扰，因此这些高流量小区站点区域可以重新定向一些剩余电力，以支持更大的语音和数据流量负载。因此，本发明通过降低（并动态地调节）低业务小区站点区域中的信号功率，增加了最需要的高流量区域中语音和数据通信的容量。
