13、主要就期刊文献进行收录，CNKI和万方数据收录文献种类较多，中国知识产权网就知识产权经行收录。从收录情况来看，维普收录最久，万方收录时间最短，但是现刊万方收录最好。从文档清晰度来说，万方最高，维普最差。万方和CNKI都有对知识产权专利的检索，维普则忽略对专利的检索。维普更新速度较快但数量逊于CNKI。就检索方法上几种网站大致相同。但在知识产权的搜索上中国知识产权网相对专业。我个人更倾向于CNKI。CNKI可以清楚快捷的下载文章，且数量较多，种类较全。二、请根据自己所选课题，在下列国外数据库系统平台中（Ei Village 、WOK-Web of knowledge、PQDT-B）分别进行检索。

40、 UMI Dissertations Publishing, 2007. . 摘要取消Broadband access has the potential to provide efficient and fair communications with free and easy inter-WLAN user mobility and seamless connectivity. However, the current WLANs protocol architecture and signaling protocol messaging do not have the capabili

With proper network architecture and network-assisted IP-mobility management signaling, WLANs

42、networks connected via the evolving broadband access networks could provide inter-WLAN user mobility over the broader distribution system medium (DSM). 61, 62, 63, 64, 65, 66 are the publications out of this thesis work. This work provides an architecture and the accompanying protocol signaling for

The proposed architecture with its required signaling capabilities leverages the Broadband-accessed central network server for inter-WLAN mobility.

44、 The uniqueness of this inter-WLAN architecture is that it not only allows the integration of the wide area network (WAN) with the high-speed backbone network, but it also provides an efficient mobility management for multiple WLANs with larger coverage. The proposed network architecture for integra
