一种双模手机及其自动选择网络的方法 Bimodal phone and automatically selects the network method

技术领域 FIELD

[0001] 本发明涉及移动通讯领域,更具体涉及一种双模手机及其自动选择网络的方法。 [0001] The present invention relates to the field of mobile communications, and more particularly, to a dual-mode phone and method for automatic network selection.

背景技术 Background technique

[0002] 随着手机用户数量以及对通信带宽需求的激增,原有GSM(全球移动通讯系统)通讯网络已难以满足,于是更快的GSM无线服务版本EDGE (Enhanced Datarates for Global Evolution,增强型数据GSM环境)网络应运而生,并迅速发展成熟;另一方面,高速率局域网也早已突破有线限制产生了无线局域网,WIFI (Wireless Fidelity,无线局域网802. lib 标准)便是无线局域网众多标准中的一种。 [0002] As the number of mobile phone users as well as the surge in demand for communication bandwidth, the existing GSM (Global System for Mobile Communications) communication network has been difficult to meet, so the faster version of GSM wireless service EDGE (Enhanced Datarates for Global Evolution, enhanced data GSM environment) network came into being, and the rapid development of mature; on the other hand, high-speed wired LANs have long been a breakthrough limit the generation wireless LAN, WIFI (wireless Fidelity, wireless LAN 802. lib standard) is a wireless LAN standard in many one kind. "移动宽带化"和"宽带移动化"的融合是通信发展的必然结果,同时支持GSM/EDGE网络和WIFI网络的双模EDGE/WIFI手机,在进行移动互联网IP(因特网协议)应用(如网页浏览、IP电话、在线聊天等)时,若利用WIFI网络则能给用户带来高速、廉价的体验,若利用EDGE网络则带给用户的是速度相对较低,资费相对较高但是通信连续性较好的体验,因而手机上集成EDGE和WIFI成为业界关注的焦点。 "Mobile Broadband" and "mobile broadband" of integration is the inevitable result of development of communication, while supporting dual-mode EDGE GSM / EDGE network and WIFI networks / WIFI phone, making mobile Internet IP (Internet Protocol) applications (such as web when browsing, IP telephony, online chat, etc.), if you use the WIFI network to give users high-speed, low-cost experience, if you give the user using the EDGE network is relatively low speeds, but relatively high tariffs communications continuity good experience, and thus integrated EDGE and WIFI become the focus of the industry on the phone. [0003] 同时,由于WIFI网络的AP(Access Point,接入点或热点)覆盖范围比EDGE网络下的基站覆盖范围小得多,在进行IP应用时,必须动态解决好选择哪个网络作为应用承载,否则无法充分利用EDGE、WIFI两种网络各自优势。 [0003] Meanwhile, since the WIFI network AP (Access Point, access point or hotspot) much smaller than the coverage area of ​​the base station under the coverage of the EDGE network, during an IP application, a choice must be dynamically resolved as the applications which network bearer otherwise unable to take full advantage of EDGE, WIFI two networks respective advantages.

[0004] 然而,现有技术中还缺乏简单有效的IP应用切换方法来实现双模手机在WIFI与EDGE网络之间自动切换,现有双模手机的网络选择方法,主要通过两种方法:手动选择,但是该方法基本的通讯连续性无法保证,大大降低用户体验满意度;自动选择,但是必须对现有网络的设备做改造,如对SIP协议(会话初始协议)进行扩展等。 [0004] However, the prior art still lacks a simple and effective method to achieve switching IP applications to automatically switch between the dual-mode phone and WIFI EDGE network, a conventional dual-mode mobile phone network selection method, mainly by two methods: manual choice, but the basic method of communication continuity can not be guaranteed, greatly reducing the user experience satisfaction; automatic choice, but must be done to transform the existing network equipment, such as the SIP protocol (session Initiation protocol) be extended so on.

[0005] 综上所述,如何在保持现有网络设备不变的情况下,实现双模手机自动选择WIFI 与EDGE网络,成为亟待解决的问题。 [0005] In summary, in the case of how to maintain the existing network equipment unchanged dual-mode phone to automatically select WIFI and EDGE network, a problem to be solved.

[0037] 如图l所示,当双模手机进行IP应用时,可能出现两种情况,一种是手机与服务器间交互IP数据,如手机浏览网页等,其应用表现为客户端/服务器模型;另外一种情况是手机与手机间交互IP数据,如IP电话、在线聊天等,其应用表现为端到端模型,而实际上不管是IP电话还是在线聊天,两端都是通过服务器来中转完成的,其应用表现还是客户端/服务器模型。 [0037] As shown in Fig L, when the dual-mode IP phone applications, it may be two cases, one is the interaction between the IP phone and the server data, such as mobile Internet browsing application performance for client / server model ; Another is interactive IP data between the phone and the phone, such as IP phone, online chat, application performance for end-to-model, in fact, whether it is an IP phone or online chat, at both ends to transit through the server completed, the application performance is a client / server model.

[0038] 当双模手机启动或进行IP应用发出的数据经TCP (传输控制协议)/UDP (用户数据报协议)模块进行处理后提交给IP模块,IP模块查找缺省IP路由表项,以确定数据报文从哪个网络接口发送出去。 [0038] When the dual-mode phone starts Submit or an IP application to process data sent via the TCP (Transmission Control Protocol) / UDP (User Datagram Protocol) IP module to module, the default IP module searches IP routing table entry, to determine which data packets are sent from the network interface.

[0039] 当路由查询结果为从卯pO网络接口发送,(如表l所示),则IP报文被路由到EDGE [0039] When the query results from the route network sockets pO transmission interface (as shown in Table L), the IP packet is routed to the EDGE

6无线模块,经空中接口进入EDGE分组域及若干数据网络,最终传输到远端服务器; 6 wireless module via the air interface into the EDGE packet data network and a plurality of domains, eventually transmitted to the remote server;

[0040] 如果手机使用Point-to-Point Protocol (简称为PPP协议,点对点协议)进行上 [0040] If the phone using the Point-to-Point Protocol (PPP protocol for short, Point to Point Protocol) carried on

网,则该网络连接就是通过卯p0等网络接口来实现。 Network, then the network connection is realized by a network interface, etc. d p0.

[0041] 表l: <table>table see original document page 7</column></row> <table>[0046] 服务器到手机方向的数据流程,依据上面的过程,以此类推。 [0041] TABLE l: <table> table see original document page 7 </ column> </ row> <table> [0046] direction to the phone server process data, according to the above process, and so on.

[0047] 本发明的双模手机的自动选择网络功能的支持与网络选择设置有关,其流程如下:显示设置人机界面,用户在人机界面上设置网络选择值,网络选择设置值为1表示支持自动选择WIFI或EDGE网络,设置为2表示仅选择WIFI网络,设置值为3表示仅选择EDGE 网络,出厂缺省值为1,即支持自动从WIFI和EDGE中选择一个最佳的网络来承载IP应用, 可以将网络选择值存入变量u8NetSwitch,并保存到存储器。 [0047] The dual-mode phone of the present invention automatically select the network support the network selection function settings related process is as follows: man-machine interface display settings, the user sets the value of network selection on the display unit, setting a value of 1 indicates the network selection automatically select WIFI or EDGE network, to select only the WIFI network represents 2, select only the set value of 3 represents EDGE network, a factory default value is 1, i.e. automatically select the best network from a WIFI be carried in and EDGE IP applications, network selection may be stored in the variable value u8NetSwitch, and stored in the memory.

[0048] 当用户启动IP应用时,首先读取设置的变量u8NetSwitch,判断u8NetSwitch取值,若为l,则自动选择网络,持续到用户终止IP应用时退出;若为2,则选择WIFI网络;若为3,则选择EDGE网络。 [0048] When a user launches an IP application, first read the variables set u8NetSwitch, u8NetSwitch value determination, if the exit is l, the network is automatically selected for the user to terminate an IP application; if 2 is selected WIFI network; If it is 3, then select EDGE network.
