Description

Dual-mode Coexisting WLAN Transmission Method

technical field

The present invention relates to a method related to data processing, in particular to a method that is applied to a wireless network transmission device and can simultaneously start an ad-hoc mode and an infrastructure mode to process different online requests. That is, a dual-mode wireless local area network (wireless network) transmission method.

Background technique

Wireless local area network transmission, as the name implies, uses light waves or radio waves as the transmission medium to transmit and receive data from computers or other wireless network transmission devices in a wireless local area network (WLAN) without the need for physical line connections. .

The wireless local area network transmission referred to in the present invention particularly refers to a transmission mode using radio waves as the main transmission medium, that is, a transmission mode based on IEEE802.11. The transmission mode currently defined in IEEE802.11 includes the following two modes:

(1) Point-to-point mode (ad-hoc mode). Refers to multiple computer-executable platforms (or peripheral devices) with wireless network transmission devices, using the same Service SetIdentifier (SSID) and the same service network channel (channel) for short-distance In the transmission mode, this mode only needs lower output power and a simpler transmission structure to complete efficient wireless network transmission between different computer executable platforms (or peripheral devices). (as shown in Figure 1A)

(2) Infrastructure mode. It means that under the basic network architecture of integrated wired and wireless, all computer-executable platforms with wireless network transmission devices in the wireless local area network must pass the access point (Access Point) that has the same service domain identification code as itself. , AP) as an intermediary to perform data transmission with other computer executable platforms (such as: service terminals) in the wired LAN. This mode belongs to the long-distance transmission architecture and is usually used for wired and wireless LANs. transmission. (as shown in Figure 1B)

The above two transmission modes can usually be set by themselves according to the actual needs, but the common problem of all current wireless network transmission devices is that they can only exist in the same mode at the same time, that is, they can only operate at the same time. For the wireless network transmission operation of a single service domain identification code, that is, the two transmission modes cannot be used concurrently. For example, some peripheral devices that are quite close to the computer executable platform, such as a mouse, only need to perform short-distance transmission with the computer executable platform (that is, use the point-to-point mode), but if At this time, if the wireless network transmission device is set to the infrastructure mode, each data transmission and reception operation between the mouse and the computer executable platform must be carried out through the above-mentioned access point, which not only increases the transmission distance The transmission speed is much lower, and the peripheral device must have greater radio wave output power to achieve the purpose of long-distance transmission, and the wireless network transmission through the access point will also increase the complexity of the transmission (such as: data security considerations) and cause an increased processing burden on the access point.

Therefore, when the computer executable platform needs to be connected to different peripheral devices or other computer executable platforms in other wired local area networks at the same time, if the two modes cannot be activated for use at the same time, it will cause overall inconvenience and cause The problem of poor performance. Therefore, how to propose a method that can simultaneously use two modes in wireless network transmission to process different online requests, so that each online request can be carried out with the most appropriate transmission mode, is necessary to effectively improve the overall efficiency of wireless network transmission in the future. Indispensable key direction of development.

First, when the computer-executable platform 100 starts to activate the wireless local area network 10, the wireless network transmission device 200 will receive the network domain setting table from the computer-executable platform 100 (step 500). Corresponding service domain identification code and service domain channel data; after receiving, the wireless network transmission device 200 will simultaneously start the online initialization operation of the point-to-point mode and the infrastructure mode (step 510), which includes receiving the network domain setting The action of initializing the firmware (firmware) in the wireless network transmission device 200 after the table, this firmware is generally stored in the control unit of the wireless network transmission device 200 to control and process each connection request (this part belongs to the known technology) After finishing the online initialization of above-mentioned two modes, just start to carry out online detection (step 520), and judge whether to produce any online request (step 530), the type of online request is generally divided into two kinds again: one is by The computer can execute the transmission request made by the platform 100 , and the receive request made by the remote service terminal 350 or the peripheral device 400 .

Before any connection request is detected, the operation process will continue to perform the connection detection action (step 520 ), and when a connection request is generated (step 530 ), then enter into step A of FIG. 3B . After entering step A, the control unit in the wireless network transmission device 200 is responsible for parsing the connection request (step 531). The purpose of this parsing is to extract the service network domain identification code in the connection request as The purpose of identification; After parsing out the service domain identification code, just use this service domain identification code to search in the network domain setting table (step 532); Determine whether to find the same service domain identification code (step 532) 533), if it indicates that this connection request must be processed according to the set mode, where the setting can be: point-to-point mode or infrastructure mode (here we use point-to-point mode as the preset processing mode); at this time Then retrieve the corresponding service domain channel of the service domain ID code in the domain setting table, and then process the connection request (step 534) through the point-to-point mode; on the contrary, if the service domain ID code of the connection request is in If (step 533) can't be found in the network domain setting table, then represent that this connection request will be processed according to normal mode (step 535) (infrastructure mode as far as this is concerned); The processing of the request is completed (step 536), if the processing is not completed, the processing is continued (step 537), if the processing is completed, it is directly returned to the step B of FIG. Step 540), before ending the wireless local area network connection, then continue to return to step 520 to continuously detect other connection requests, otherwise, if the wireless local area network connection is ended, the entire operation process of the method of the present invention is ended.
