Description

一种多无线接入技术中的网络选择方法及系统 技术领域
本文涉及但不限于通信领域，尤其涉及一种多无线接入技术中的网络选择方法及系统。
背景技术
随着无线通信技术和标准的不断演进，移动分组业务得到了巨大的发展，单终端的数据吞吐能力不断提升。以长期演进(LTE，Long Term Evolution)系统为例，在20M带宽内可以支持下行最大速率100Mbps的数据传输，后续的增强的长期演进(LTE-A，LTE Advanced)系统中，数据的传输速率进一步提升，甚至可以达到1Gbps。
终端数据业务量膨胀式的增长，让所有的网络资源逐渐力不从心，尤其是在新一代通信技术比如3G、LTE还无法广泛布网的情况下，随之而来的是用户速率和流量需求无法满足，导致用户体验变差。据预测，未来支持的设备不管在数量上还是业务速率上都将是目前的10到100倍，而有些低时延超可靠业务要求的端到端时延将缩短到目前的五分之一。因此，网络发展需要更高带宽、更低时延、更高的可靠性和更强的智能化能力，多张网络简单的互操作并不利于整体效率以及用户体验的提升，需要新型的多网融合技术。
由于未来的业务形态和场景是多样化的，为了满足各种需求，需要有多种类型的小区存在，从网络制式上来讲，会存在第二代手机通信技术(2G)、第三代移动通信技术(3G)、第四代移动通信技术(4G)、第五代移动通信技术(5G)，无线局域网(WLAN，Wireless Local Area Network)，从覆盖范围上来讲，会存在宏小区，微小区，超密集网络(UDN，Ultra Dense Network)小区，这些小区都有其各自的特点。2G、3G、4G、5G小区为蜂窝小区，支持的分组业务随着技术演进其速率逐步提升；WLAN在当前已经普遍应用，尤其是基于电气和电子工程师学会(IEEE，Institute of Electrical and Electronics Engineers)802.11标准的无线局域网，采用非授权频谱，在家庭、企业甚至 是互联网被广泛应用于热点接入覆盖。宏小区覆盖范围广，为了提高系统容量，提出了微小区技术，超密集网络小区可以看作是微小区增强技术的进一步演进。在UDN网络中，传输节点密度将进一步提高，覆盖范围进一步缩小，每个传输节点同时只服务一个或很少的几个终端。因此，终端在多无线接入技术(multi RAT，multi Radio Access Technologies)中，如何进行网络的选择尤为重要。
