Description

用于 UE网络切换的信息处理方法和基站
技术领域
本发明涉及通信技术领域, 尤其涉及一种用于用户设备(UE ) 网络切换 的信息处理方法和基站。
背景技术
移动终端设备的快速普及催生了数据流量的爆发式增长, 也成为运营商 移动网络当前最大的挑战。 目前, 运营商正在加速 3G 网络部署与优化, 并 逐步向下一代移动通信网络 (4G)演进。
在全球范围内,运营商无线局域网( WLAN )部署仍在快速推进。据 In-Stat 发布的新一期题为 "无线保真(Wi-Fi )热点: 移动运营商的 3G分流方案" 的研究报告, 2010年全球热点场所为 42.1万,预计将在 2015年增至超过 120 万个。 而在国内, 运营商 3G网络带来的移动流量危机, 也驱动了 WLAN的 部署浪潮。
急剧增长的移动数据流量必须通过 3G网络或者未来长期演进( LTE )网 络进行承载。 但无论是 3G还是 LTE, 考虑到成本等各因素, 它们在分流移 动数据流量能力上明显不如 WLAN。

4G时代不会对 Wi-Fi带来影响。 即便 4G网络可以提供高得多的速度, 但是移动互联网流量和用户数量的陡增还是会堵塞频谱, 并造成现在 3G 网 络中存在网络中断等问题。 与此同时, 由于 4G属于授权频谱, 因此它还是 一种相对昂贵且有限的方式。 "随着 Wi-Fi被广泛应用于现在的智能手机设 备中, 利用 Wi-Fi从 3G/4G网络中分流流量仍将是一种极为有效且低成本的 方式。 "
