论文摘要
异质无线网络HWN是由不同无线电访问技术大鼠制成的组合网络。下一代网络NGN将提供高带宽连接性和高数据吞吐量，并为用户的QoS需求提供平稳的支持，在这种情况下，具有多面端子终端的用户将能够连接到不同的无线技术，例如802.16，802.11家族和细胞家庭UMTS，HSPA和HSPA，HSPA和LTE。 NGN的想法是，考虑到用户所请求的用户的QoS，用户将不会与一个单个操作员的合同捆绑在一起，但用户将能够选择无线电访问网络鼠。本文着重于网络选择策略和技术间的交接，我们将介绍存在网络选择方法的描述，我们将讨论这种方法的优点和弱点，我们将提供我们的观点。
Heterogeneous Wireless Networks HWNs are combined networks made of different Radio Access Technologies RAT. Next-Generation Networks NGN will provide high bandwidth connectivity and high data throughput with smooth support for the user's QoS requirements, in this context, users with multi-interface terminals will be able to connect to different wireless technologies such as 802.16, 802.11 families and cellular families UMTS, HSPA and LTE in the same time. The idea of NGN is that users will not be tied with a contract with one single operator but, users will be able to choose the Radio Access Network RAT considering the user's QoS requested. This paper focuses on the network selection strategies and the inter technologies Handoff, we will present a description of the existed methods of network selection, we will discuss the merits and the weakness of such method and we will give our point of view.
