1 subway in Nanjing, by adhering the principle of “Human is the first” and analyzing the advanced experiences of designing seamless exchange at home and abroad, and considering the overall traffic arrangement、land use characteristic and humanity environment.

Taking Nanjing for example, the paper gives some planning solutions in such aspects as the seamless exchange between urban mass transit and other traffic means, improving the exchange convenience at the knot of urban mass transit, etc.

From the viewpoint of reducing channel-cutoff,this paper discusses the concept and mechanism of seamless handover technology,describes the principle of how the technology enhances the communication quality,analyzes the concept and process of the frequency hopping technology in seamless handover technology.

11WLAN and GPRS, this paper presented a novel seamless handover control scheme.

To enable users to access to the proper network at any time,and make seamless handover when moving between different networks,multi-mode terminal design has become a very important issue.

Seamless Handoff based on IP for 3G Network;

Research on Route Optimization and Seamless Handoff in Mobile IP;

A novel scheme of seamless handoff in MPLS-based mobile IPv6 network is proposed, which shortens the handoff latency by confining the re-establishment range of the label switching path (LSP) and decreases the packet loss rate by bicasting data to the mobile host during its switching.

Soft seamless switching in dual-loop DSP-FLL for rapid acquisition and tracking;

A novel seamless switching method of scalable video stream is presented.

Upon analysis of the traditional fare clearing model,this paper proposes a synthetical fare clearing model based on big probability priority in multi-way choice,which gives dual attention to many factors like passenger\'s multi-way choice,barrier-free transfer and so on,and makes the income distribution more reasonable.
