The present invention relates to a wireless communication connection device, and more particularly, an RF data transmission / reception module and a wireless local area network (WLAN) radio for a wireless personal area network (WPAN) or a wireless sensor network (WSN) wireless communication connection service. In a state in which a wireless LAN data transmission / reception module for communication connection service is also used in combination, the surrounding environment of the electronic device is based on whether the access point (AP) is called "AP". After determining whether the environment or the WPAN / WSN service environment, if the presence of the AP is determined to determine that the surrounding environment of the electronic device is a WLAN service environment, through the WLAN data transmission / reception module , WLAN type wireless communication connection service (Wireless LAN data transmission / reception service) is selectively implemented.In contrast, since the presence of AP is not confirmed, the surrounding environment of the electronic device is WPAN / WSN. If it is determined that the system environment, the systematically coordinated and arranged computer modules that can selectively implement the WPAN / WSN type wireless communication connection service (RF data transmission / reception service) through the RF data transmission / reception module, In this way, within one device, the WLAN wireless communication connection service and the WPAN / WSN wireless communication connection service can be made to be implemented in a compatible manner, regardless of where the user is located (service area). In addition, the present invention relates to a wireless communication connecting device capable of inducing a stable implementation of a series of wireless communication connection services.

Recently, as the infrastructure related to electronics and electricity has grown rapidly, various kinds of wireless communication to guide data communication between wireless nodes and electronic devices by wirelessly connecting electronic devices such as PCs, PDAs and mobile phones to a series of wireless nodes. Connecting devices are being developed and distributed.

It receives the side wireless LAN data (AP side wireless LAN data), and serves to stably store in the processing buffer 41a.

In this situation, the wireless LAN data analysis / conversion unit 44 controlled by the wireless LAN data transmission / reception control unit 41 performs the function of the wireless LAN data receiving unit 43 and performs the wireless node 4 side wireless LAN. When data (AP side WLAN data) has been stored in the processing buffer 41a, the characteristics (address information, frame length information, packet error rate information, channel utilization information, authentication information, real data, etc.) of the corresponding WLAN data are analyzed. Then, a corresponding action (for example, an action of notifying the AP side of the fact that the wireless LAN data has been received, etc.) is taken to the AP 3 side, and a series of conversion routines are activated to transmit the WLAN data to the electronic device ( 2) It converts the data suitable for the side (for example, the data suitable for the PC, the data suitable for the PDA, the data suitable for the mobile phone, etc.) and delivers the converted data to the wireless LAN data transmission / reception control unit 41 side. It is.

Of course, as described above, the data transmitted to the wireless LAN data transmission / reception control unit 41 passes through the wireless network connection control module 10, and then undergoes a procedure of being quickly transmitted to the electronic device 2. On the electronic device 2 side, it is possible to flexibly form a stable data wireless reception relationship with the wireless node 4 side.

A message operator for searching; A response message check unit, controlled by the data transmission / reception environment selection control unit, for checking whether a response message corresponding to the AP search message is returned from a specific AP located near the electronic device; Controlled by the data transmission / reception environment selection control unit, and when it is determined that the response message is returned by the response message check unit, network information of a specific AP mounted in the response message is sent to the wireless network connection control module. Informing the wireless network connection control module to proceed with a data transmission / reception procedure between the electronic device and the wireless node through the WLAN data transmission / reception module under a WLAN service environment. If it is determined that the response message is not returned, the non-response result of the response message is notified to the wireless network connection control module, so that the wireless network connection control module receives the RF under the WPAN / WSN service environment. The electronic device and the wireless node through a data transmission / reception module Peripheral communication environment notification encouraging its progress data transmitting / receiving procedure, a wireless communication connection device characterized in that comprises a. The method of claim 2, wherein the data transmission / reception environment selection control unit reads the network information of a specific AP mounted in the response message when it is determined that the response message is returned by the response message check unit. Afterwards, by transmitting a ping message (Ping message) to the AP, the wireless communication connection device further comprising an AP availability check unit for checking the availability of the AP.
