Method for automatically establishing a wireless network topology

The present invention relates to a wireless network topology, and more particularly to a method for a user to automatically form a wireless network topology by simply turning on the wireless network device at different points in time.

In recent years, the topologies of wireless network protocols (such as IEEE 802.11, WiMAX, etc.) have become the main direction of wireless network development, mainly because wireless networks are not built. The layout of the physical line needs to be considered, and the user's position on the mobile terminal device (such as a notebook computer or tablet) is not interfered or dragged by the network route, so that the user can greatly improve the time when surfing the Internet. Convenience.

According to the results of the wireless network usage survey conducted by Taiwan Network Information Center (TWNIC) for people living in Taiwan who are over 12 years old, up to 81.19% of the population will use laptops and desktop computers. With terminal devices such as smart phones, using wireless local area network (WLAN) to access the Internet, meaning that more and more people are used to using wireless networks, although wireless networks have many benefits, but for businesses or individuals, How to establish a network cable topology is a big problem. Generally speaking, when a user wants to construct a network topology through multiple wireless network devices (Access Point, AP for short), it is usually necessary to manually set the following information:

(1) Service Set Identifier (SSID): is the name or identification code of a wireless network, and the wireless network devices must have the same service setting identifier to join the same wireless. In the network; (2) wireless network mode: communication standards, such as: IEEE802.11b, IEEE802.11g or WiMAX, etc., mainly because of different communication standards, respectively, different transmission rates, such as 802.11g maximum transmission The rate is up to 54Mbps, and "802.11b has a maximum transmission rate of only 11Mbps. Therefore, these wireless network devices must be consistent with the set wireless network mode. (3) Wireless channel: wireless network device Working carrier frequency, for example: 2.4GHz (802.11b/g/n), 5GHz (802.11a/n/ac); (4) Security Settings: ie encryption (eg WEP, WPA, WPA2) ) and encryption keys, etc., mainly because the data of the wireless network is air-based, so others can intercept the data through related technologies, if the data does not have any encryption method, Then others can straight If the content is known, but if the data is encrypted, the other people will not be able to know the content without understanding the encryption method. Therefore, the wireless network devices must be set to the same. Security settings, in order to successfully encrypt and decrypt data; and (5) other settings: such as bandwidth management, bandwidth integration (trunking) and other information.

As can be seen from the above, if the user needs to use 30 wireless network devices to construct a wireless network topology used by an enterprise, it must be set for each wireless network device, causing the user to reset the settings. 30 times of the above information, this action undoubtedly consumes too much working time of the user, resulting in the user not being able to properly handle other work. In addition, when the user sets the wireless network device, if it is set inadvertently The wrong information will cause the wrong setting of the wireless network device to be unable to work properly, so that the user must re-check all the setting information of the wireless network device, so that the user's work efficiency is low, and further, the complicated setting process, It also makes the user subjectively think that the wireless network device is poorly designed, and reduces the user's willingness to use, thereby affecting the sales performance of the operator and the brand loyalty of the user.

Therefore, when a user wants to construct a wireless network topology through multiple wireless network devices, how can he quickly form a wireless network extension without additionally setting the same information multiple times? Park, in order to streamline the user's setting process and improve the user's work efficiency, has become an important issue that every wireless network operator attaches great importance to and has yet to work hard to solve.

In view of the above-mentioned establishment process of the traditional wireless network topology, which is too complicated and causes users to be troubled in setting, the inventor is based on the technical experience and network expertise accumulated in the network equipment for many years. The characteristics of the network topology, carefully researching various solutions, and after continuous research, experimentation and improvement, finally developed and designed a method for automatically establishing a wireless network topology of the present invention, with the aim of making the user In a simple operation step, the wireless network topology can be quickly and automatically formed for the purpose of high efficiency and simplification.

The identification code and a first wireless node synchronization data (eg, wireless network mode, wireless channel, security settings, other settings, etc.), and begin to accumulate a first time period, 嗣, which will search for other through the antenna unit a wireless network device, and after searching for other wireless network devices, can read one of the other wireless network devices, and the second service setting identifier and other wireless network devices start counting and accumulate one of the second timings. During the period, after the central processor determines that the second timing period is less than the first timing period, a connection with other wireless network devices is established, and The first wireless node synchronization data is transmitted to other wireless network devices, so that other wireless network devices can modify the second service setting identifier and the second wireless node synchronization data to the first service setting. The identification code and the first wireless node synchronization data. Finally, after determining that the first time period has reached a set period, the central processing unit stops searching for other wireless network devices, and transmits a stop scanning message, the first The service setting identifier and the first wireless node synchronization data to the other wireless network devices that have established the connection, so that all the established wireless network devices have the same service setting identifier and the wireless node synchronization data, so that The user only needs to trigger the input unit on each wireless network device to quickly establish a wireless network topology, which greatly improves the user's convenience in setting.

After the second timing period, a connection is established with the other wireless network device 11B, and the first wireless node synchronization data of the first wireless network device is transmitted to the other wireless network device 11B, and the other wireless network After determining that its second timing time is less than the first timing period of the wireless network device 11A, the road device 11B will modify its own second service setting identification code (eg, S2) and the second wireless node synchronization data. Set an identification code (eg: S1) and the same for the first service The wireless node synchronizes the data. Finally, after determining that the first time period has been accumulated for a set period (for example, 10 minutes), the wireless network device 11A stops searching for other wireless network devices and transmits a stop scan. Sending a message to the other wireless network device 11B to cause the other wireless network device 11B to stop searching for other wireless network devices, and at the same time, the wireless network device 11A will once again set its own first service identification code. And transmitting, by the first wireless node, the data to the other wireless network device 11B that has established the connection, so that the wireless network devices 11A, 11B can quickly establish a wireless network topology and ensure that the wireless network topology is established. The connected wireless network devices 11A, 11B can have the same service setting identification code and wireless node synchronization data, so that if the user needs to establish a wireless network topology with 30 wireless network devices, only By triggering each wireless network device, a wireless network topology can be automatically generated without having to repeatedly set the same service setting identifier 30 times as in the conventional method. The wireless node synchronizes the data, which greatly improves the user's work efficiency and convenience. At the same time, it can also prevent the user from finding the wrong wireless network device due to inadvertent setting error during the repeated setting process. And then reset.
