Since the year 2000, silicon intellectual property (SIP), which can minimize the gap in ‘design productivity’ that exists with systems-on-chip (SOC), has become one of the most important factors in the development of integrated circuit (IC) products in the SOC era. Although SIP is very important for IC industry development, complicated business, technical as well as legal issues inside SIP transactions have hindered successful transactions and the integration of SIPs into SOCs. Thus, web-based SIP e-Commerce mechanisms, called SIP Malls, have emerged, aiming to resolve complex SIP issues. To maintain its leading position and competitiveness in the World's IC industry, as well as the value added by SOC products in Taiwanese IC firms, the Taiwanese government has developed SIP Malls, using innovation policy tools. However, the Taiwanese SIP Mall industry remains immature. No existing Taiwanese SIP Malls generate a profit or account for a significant share of worldwide SIP transactions. This research will develop an analytical framework for defining an innovation policy portfolio that aims to develop Taiwan's SIP Mall industry, so that it will enhance the value added of SIP Malls and, thus, the nation's competitiveness in the SIP and IC industries, something which already has become one of the Taiwanese government's major concerns. The industry innovation requirements (IIRs) are summarized using the Delphi method. Meanwhile, the major IIRs identified by Decision Making Trial and Evaluation Laboratory (DEMATEL) are introduced. After the IIRs are derived, the relationships between the IIRs and innovation policy tools are derived by Grey relational analysis (GRA). Then, the innovation policy tools are clustered, based upon the Grey grades derived by GRA. Finally, reconfigured innovation policy portfolios are presented for the Taiwanese government's policy definition. The results demonstrate that developing an innovative policy portfolio that includes scientific, technical, educational, public enterprise, information, legal and regulatory, financial, and taxation policy tools will be the most necessary step towards developing Taiwan's SIP Mall industry. 相似文献

在SIP网络出现之前,以IP网络为传输系统的H.323网络已得到广泛应用,因此,应用SIP网络时必须考虑SIP网络和H.323网络的互联问题。文章研究SIP网络与H.323网络互通的功能实体IWF(互通的功能实体称为IWF,即Inter Working Function互通功能体),经测试此方案是合理可行的。 相似文献

3GPP在UMTS R5中提出IMS作为下一代网络(NGN)技术在移动通信中的实现,但IMS业务触发机制的缺陷给交互管理带来挑战.把IMS中业务特征冲突分为SCFI(Single Component Fea-ture Interaction)和MCFI(Multi-component Feature Interaction)两类,利用SIP协议的可扩展性携带业务触发信息,提出解决MCFI类业务冲突的算法及方案.此方案为3GPP Service Broker标准制定提供了参考. 相似文献
