Description

一种智能手机无线接口切换方法A smart phone wireless interface switching method

技术领域 technical field

本发明涉及移动互联网领域和无线通信领域,特别涉及一种智能手机无线接口切换方法。The invention relates to the fields of mobile Internet and wireless communication, in particular to a method for switching wireless interfaces of smart phones.

背景技术 Background technique

目前智能手机所处的无线环境是一个多种异构网络并存的无线通信环境,包括蜂窝网、数字视频网、无线城域网、无线局域网、家庭网络、个人网络等等。而且这些网络本身又有很多标准,例如蜂窝网络就包括W-CDMA、CDMA2000、TD-SCDMA、GPRS等无线接入技术。这些异构的无线网络具有不同的特性,例如Wi-Fi具有较高的网络带宽,费用较低,但终端设备的移动支持性差,传输距离短,能耗相对较高,而GPRS/UMTS则支持设备的移动性,传输距离广,能耗低,但传输速率低,成本高。这些具有不同特性的异构网络在某种程度上具有互补作用,在智能手机上充分利用不同异构网络,能有效提高手机的用户体验和提高应用运行的性能。The current wireless environment for smartphones is a wireless communication environment in which multiple heterogeneous networks coexist, including cellular networks, digital video networks, wireless metropolitan area networks, wireless local area networks, home networks, personal networks, and so on. Moreover, these networks have many standards. For example, cellular networks include wireless access technologies such as W-CDMA, CDMA2000, TD-SCDMA, and GPRS. These heterogeneous wireless networks have different characteristics. For example, Wi-Fi has high network bandwidth and low cost, but the mobile support of terminal equipment is poor, the transmission distance is short, and energy consumption is relatively high, while GPRS/UMTS supports The mobility of the equipment, the transmission distance is wide, and the energy consumption is low, but the transmission rate is low and the cost is high. These heterogeneous networks with different characteristics have complementary effects to a certain extent. Making full use of different heterogeneous networks on smart phones can effectively improve the user experience of mobile phones and improve the performance of application operations.

目前的智能手机大多都具有多个无线接口,例如同时具备3G或GPRS,Wi-Fi,蓝牙等无线通信技术。然而,目前智能手机将无线网络选择的权利都交付给用户,用户必须根据当前所处的环境和正在运行的应用程序,来决定选择合适的无线网络接入(市场主流的手机操作系统Windows Mobile,Android,iPhone都是采取这样的措施)。这种手动选择方式在效率方面和使用方便性上具有很大的限制。简单地在智能手机侧采取自动选择方式,即通过软件自动实现选择功能,自动关闭当前正在使用的无线接口,然后重新打开另一个无线接口,导致网络的中断。例如,当前智能手机正在通过3G访问YouTube视频网站,这时手机发现当前环境的WiFi信号强,适合用户采用无线局域网的方式访问网络,因此软件自动关掉3G的数据传输通道,打开Wi-Fi接口,并扫描信道,匹配合适的接入点,验证用户信息,重新分配智能手机IP地址,再连入网络,这时原有的网络连接早已中断,由于IP地址的变化,新的网络也不能从中断处开始,只能重新开始,这会大大降低手机的用户体验。因此,手机无线接口的自动切换能利用各种无线异构网络的性能,但同时会带来网络中断问题,这是目前实现自动切换主要的困难。Most of the current smart phones have multiple wireless interfaces, such as 3G or GPRS, Wi-Fi, Bluetooth and other wireless communication technologies. However, at present, smart phones hand over the right to choose the wireless network to the user, and the user must decide to choose a suitable wireless network access according to the current environment and the running application program (the mainstream mobile phone operating system in the market, Windows Mobile, Both Android and iPhone take such measures). This manual selection method has great limitations in terms of efficiency and ease of use. Simply adopt the automatic selection method on the smart phone side, that is, automatically realize the selection function through software, automatically close the wireless interface currently in use, and then reopen another wireless interface, resulting in network interruption. For example, currently the smart phone is accessing the YouTube video website through 3G. At this time, the mobile phone finds that the WiFi signal in the current environment is strong, which is suitable for users to access the network through wireless LAN. Therefore, the software automatically turns off the 3G data transmission channel and turns on the Wi-Fi interface. , and scan the channel, match the appropriate access point, verify the user information, reassign the IP address of the smartphone, and then connect to the network. At this time, the original network connection has been interrupted. Due to the change of the IP address, the new network cannot start If you start where you left off, you can only start over, which will greatly reduce the user experience of the mobile phone. Therefore, the automatic switching of the wireless interface of the mobile phone can take advantage of the performance of various wireless heterogeneous networks, but at the same time it will bring the problem of network interruption, which is the main difficulty in realizing automatic switching at present.

在终端IP地址改变的情况下,同时消除网络连接终端,保证当前业务连续性的工作大致可以分为三类。第一类是,采用主从网络的方式,选择一个无线网络作为终端用户的主网络,其余的无线网络作为终端用户的从网络,当用户从无线网络切换到另一个无线网络时,所有的数据流都必须通过主网络流向终端用户(Pahlavan,Krishnamurthy,Hatami,Ylianttila,Makela,Pichna.Handoff in hybrid mobile data networks.2000)。第二种,添加一种称为移动网关的基础设施,它作为终端用户和网络之间的代理,无论终端用户所在何种无线网络环境中,所有的数据流都会通过移动网关再流向终端用户(Balasubramanian,Mahajan,and Venkataramani,Augmenting Mobile 3G Using WiFi.MobiSys,2010.)。第三种,扩展当前的TCP/IP协议,让它支持设备的移动性,例如通过添加移动IP来支持异构无线网络的支持。然而,无论添加移动网关的设施也好,修改现有的网络通信协议也好,都需要实现庞大而复杂的工程的支持,并且难以和现有的技术兼容,很多方面需要推到重来。因而,这些保持业务连续工作无法在短期内实现和部署。When the IP address of the terminal changes, the network connection terminal is eliminated at the same time, and the work to ensure the continuity of the current business can be roughly divided into three categories. The first type is to adopt the master-slave network method, select one wireless network as the main network of the end user, and the rest of the wireless networks as the slave network of the end user. When the user switches from a wireless network to another wireless network, all data All streams must go through the main network to end users (Pahlavan, Krishnamurthy, Hatami, Ylianttila, Makela, Pichna. Handoff in hybrid mobile data networks. 2000). The second is to add an infrastructure called a mobile gateway, which acts as an agent between the end user and the network. No matter what kind of wireless network environment the end user is in, all data flows will flow to the end user through the mobile gateway ( Balasubramanian, Mahajan, and Venkataramani, Augmenting Mobile 3G Using WiFi. MobiSys, 2010.). The third is to expand the current TCP/IP protocol to support the mobility of equipment, for example, to support heterogeneous wireless networks by adding mobile IP. However, no matter whether it is adding a mobile gateway facility or modifying the existing network communication protocol, it needs to realize the support of a huge and complex project, and it is difficult to be compatible with the existing technology, and many aspects need to be reinvented. Therefore, these business continuity efforts cannot be implemented and deployed in the short term.
