用于 CPE的数据访问方法和 CPE 技术领域 本发明涉及通信技术领域,具体来说是一种用于 CPE( Customer Premises Equipment, 用户终端设备) 的数据访问方法及一种 CPE。 背景技术 随着无线通信技术的高速发展, 网络规模的不断扩大, 3G技术已越来越 广泛地应用到了人们的日常生活中。 USB 接口作为目前使用的一种通用接 口,被广泛应用到了无线通信终端, 如 3G技术中广泛使用的 CPE ( Customer Premises Equipment, 用户终端设备) 中, 以作为终端设备的接口, 同时传输 语音和其他数据信息。 目前, CPE类产品主要有两种:一种是在 CPE主板内部直接集成一个无 线的模块, 可以实现拨号、 上网、 打电话等一些普通的功能; 另一种是有适 配器的 CPE产品, 通过适配器 CPE可以适配多种调制解调器, 尤其是 USB 调制解调器, 该适配器具有一个 USB接口, 只要插上一个 USB调制解调器, 而不论该 USB适配器为何种制式, 经过适配器适配, 均可实现上述第一种的 业务。
CPE产品使用互联网业务时, 由于不同的业务由不同的运营商经营, 用 户在使用或下载这些业务时, 与 CPE的 SIM ( Subscriber Identity Module )卡 所对应的运营商提供的业务会有较快的使用和下载速度, 而由其他运营商提 供的业务则会造成 CPE 接入终端设备网速受限以及跨运营商网络之间业务 访问瓶颈的尴尬, 如 SIM卡运营商为电信的用户在访问网通提供的业务时, 常常会出现访问或者下载速度慢, 甚至无法访问的现象。 因此, 当用户在下 载多个资源的时候, 为了达到较好的下载质量, 就必须人为地选择与本 SIM 卡所对应的运营商相符的网络,然而当资源有限或者不知道资源所属的时候 , 就无法选择合适的运营商, 进而无法保证下载速度和质量。 另外, 在拨打电 话的时候也存在同样的问题, 因为跨运营商交费高于同一运营商内费用, 常 常给用户造成费用负担。
