With the development of network technology, especially the continuous expansion of data network coverage, it provides great convenience for the networking of intelligent terminals. Intelligent terminals use the wireless network technology to realize information exchange and information dissemination between each other, which brings great convenience to the user's life. However, since the data network relies on the operator, the operator charges the user a certain amount of fees through the use of the data network. Therefore, how to effectively assist the user in managing and controlling the usage of the data network has become a problem that today's smart terminals need to solve. problem.

To solve the above problem, the present invention provides a data traffic monitoring method for an intelligent terminal. 1 is a schematic flowchart of a data flow monitoring method of an intelligent terminal according to a preferred embodiment of the present invention. It can be seen from the figure that the data flow control method of the intelligent terminal provided by this embodiment mainly includes the following steps:

Obtaining a current network connection form of the smart terminal;

- when the current network connection form of the intelligent terminal is a data network; monitoring an uplink rate or a downlink rate of the data network in real time;

- When the uplink rate or downlink rate is greater than a threshold, an alert signal is generated and sent out.

Specifically, in this embodiment, the smart terminal may implement automatic monitoring of the current network connection form of the smart terminal. At present, intelligent terminals on the market can basically implement wireless Internet access technologies through cellular data networks (referred to as data networks in the present invention) and WiFi.

Among them, cellular network or mobile network (Cellular network) is a mobile communication hardware architecture, the mobile phone The service is divided into small hexagonal sub-areas, and each cell has a base station, which forms a structure resembling a "cellular". Therefore, this mobile communication method is called a cellular mobile communication method. Cellular networks can be divided into analog cellular networks and digital cellular networks, which are mainly distinguished from the way information is transmitted. The reason why cellular networks are widely used is the result of a mathematical conclusion that the planes are covered by a circle of the same radius, when the center of the circle is at the center of each regular hexagon of the regular hexagonal grid, that is, when the center of the circle is in the square of the regular triangle. The number of circles used is the least. Although the use of a minimum number of nodes can cover the largest area of the graph, even if the node is required to be solved on a grid with a translational characteristic like a lattice, in the communication, the circle is used to express the practical requirements. It is usually reasonable, so a neat triangle mesh or a simple hexagonal grid is the best choice for saving equipment construction costs. The network thus formed is covered and shaped very much like a cell, so it is called a cellular network. The cellular network consists of the following three parts: mobile station, base station subsystem, and network subsystem. A mobile station is a network terminal device, such as a mobile phone or some cellular industrial control device. The base station subsystem includes a mobile base station (large tower), a wireless transceiver device, a private network (generally a fiber optic), a wireless digital device, and the like. The base station subsystem can be seen as a converter between the wireless network and the wired network.

Wi-Fi is a technology that allows electronic devices to connect to a wireless local area network (WLAN), typically using a 2.4G UHF or 5G SHF ISM radio frequency band. Connecting to a wireless LAN is usually password protected; but it can also be open, allowing any device within the WLAN range to be connected. Wi-Fi is a brand of wireless network communication technology and is owned by the Wi-Fi Alliance. The goal is to improve interoperability between wireless network products based on the IEEE 802.11 standard. It currently uses the 802.11b standard, the theoretical data rate can reach 11Mbit, the actual physical layer data rate supports 1, 2, 5.5, 11Mbit adjustable, covering from 100-300m. With the development and improvement of technologies and protocol standards such as 802.11g/a, 802.16e, 802.11i, WiMAX, and the rapid response of the Wi-Fi Alliance to the market, Wi-Fi is entering a stage of rapid development. Among them, 802.16 (WiMAX Worldwide Interoperability for Microwave Access), which is the successor to 802.11b development, has been officially approved in January 2003, although it uses a different frequency band than 802.11b (10-66GHz). ), but as a wireless metropolitan area network (WMAN) technology, it can complement the 802.11b/g/a wireless access hotspot to build a broadband wireless technology that completely covers the metro. Wi-Fi/WiMAX, as a wireless extension technology for Cable and DSL, provides mobility and flexibility for mobile users to provide true wireless broadband access services, enabling bandwidth characteristics and QoS quality of traditional broadband access technologies. extend.

In this embodiment, the current network connection form of the smart terminal is obtained; and the current network connection form of the smart terminal is determined according to different information of the data network and the frequency band of the WiFi; When the current network connection mode of the smart terminal is a data network, in this embodiment, the smart terminal can monitor the uplink rate or the downlink rate of the data network in real time.

The rate at which the wireless terminal downloads data from the base station or the network;

In this embodiment, when the smart terminal monitors and finds that the uplink rate or the downlink rate of the data network is greater than a threshold, the smart terminal generates an alarm signal and sends the alarm information. Therefore, the user can know that the uplink rate or the downlink rate that the smart terminal needs to provide the data network is too high according to the alarm signal sent by the smart terminal, and the smart terminal will be short at the uplink rate or the downlink rate. The traffic consumption of a large data network is generated in a time, which causes a high waste of funds. Further, the user may choose to change the wireless network connection mode of the smart terminal to a WiFi connection or directly close the data of the smart terminal. Internet connection.
