我公司GSM网端局兼做关口局的华为MSC交换机已经在网运行3年多,一直运行稳定。本人几年来一直负责该设备的维护,在我们平时日常维护中。可能对位置更新、预付费主被叫Overlay触发时的表格处理流程不很了解.所以在处理局数据配置、投诉问题定位解决时有点麻烦,根据自身的切身实践.下面浅谈用户数据在表格中的处理流程,与大家共享,以此抛砖引玉。 相似文献

This concise 181-page book introduces guidelines for those interested in improving their status in the hierarchy of modern, technology-driven organizations. The book is divided into five parts. Part One is an introduction to the guidelines needed to succeed in technological hierarchies. Part Two consists of 11 chapters that present the tale of I. M. Sharp, who went from being an average high school student to being a successful technocrat. Part Three consists of seven chapters that introduce a methodology that technologists can use in the management of high-technology projects. Part Four consists of six chapters that explain how to select projects, evaluate ideas, and thrive in a technological organization. Part Five consists of three chapters that summarize all the laws, corollaries, rules, and precepts presented in the book, serving as an excellent reference. The ideas in the book are presented in brief, practical, and reader-friendly format and the examples facilitate the understanding of the key points covered. The book will certainly interest readers who are looking for a career in a technology-driven organization. 相似文献

Infrared‐induced transient absorptions in the millisecond and sub‐picosecond time domains have been used to study the dynamics of charge carriers of a conducting polymer, poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonic acid) (PEDOT:PSS). On the millisecond timescale, the transient absorption is ascribed to a thermal effect induced by absorbed infrared light. The decay of the transient absorption is limited by the transport of heat from the polymer film to the substrate and corresponds to the decay kinetics of infrared‐induced changes in the resistivity of the material. Near 1.5 eV, the infrared‐induced absorption can be modeled in terms of an interband transition. The assignment of the optical transients in terms of carrier heating opens the possibility to study charge carrier thermalization processes using short laser pulses. Pump‐probe spectroscopy on a sub‐picosecond timescale shows that the initial thermalization of the excited charge carriers occurs with a time constant of less than 500 fs, i.e., faster than for noble metals. 相似文献
