提出了一种在异构移动的网络中进行切换时提高TCP性能的方案。当前，正在积极地进行关于3G蜂窝网络与WLAN之间的互通的研究。要实现这两种技术的融合，需要解决网络体系结构、移动性管理、安全性等问题。实现WLAN和3G网络之间的无缝切换是一个重要的问题。在本文中，我们提出了一些问题，开发一个网络，支持WLAN和3G蜂窝网络之间的互通，特别是专注于TCP的挑战。我们研究了一个TCP的性能在WLAN和3G蜂窝网络之间的系统间切换，并讨论了一些问题，目前的TCP的经验在系统间切换，并提出了一些方案，以提高TCP的性能。
A scheme for enhancing the TCP performance when a handoff occurs within a heterogeneous mobile network is proposed. Currently, the research on the interworking between 3G cellular networks and a WLAN is actively being conducted. To integrate these two technologies, there are many issues such as the network architecture, mobility management, and security which should he solved. Implementing a seamless handoff between WLAN and 3G networks is an essential issue. In this paper, we present some issues to develop a network that supports interworking between WLANs and 3G cellular networks, especially focusing on the TCP challenges. We examine a TCP performance during an intersystem handoff between a WLAN and a 3G cellular network and discuss some problems that the current TCP experiences during intersystem handoff and propose some schemes to improve TCP performance.
