If head unit 200 transmits AP status request together when transmitting supplier's project of probe requests thereby packet, then at least one user's terminal 100 or AP are not only supplier's project that AP state information is also included in probe response packet by the service that can implement.Here, now at least one each data processing amount, the number being connected to the terminal of at least one present user's terminal 100 or AP usage data, AP number, the AP number of all sideband channels and the signal strength signal intensity etc. of AP in same channel of user's terminal 100 can be comprised in AP state information, transmit AP state information.
Here, the AP number in same channel, the AP number of all sideband channels confirm because of producing radio interference in Wi-Fi communication, and the signal strength signal intensity of AP is because signal strength signal intensity is better, and the error rate that can reduce packet confirms.
Accordingly, if comprise AP state information at probe response packet and transmit this probe response packet, then head unit 200 analyzes the AP state (S70) transmitted.Head unit 200 quantizes to each information distribution preferred sequence available scores according to affect the degree that data use in AP information when analyzing AP state.
Just, identical with the situation forming service catalogue, if set by user when analyzing AP state and there is the AP do not used, then head unit 200 can by except this AP be in analytic target.
Afterwards, the service catalogue formed and AP state are shown in interface portion 210 (S80) by head unit 200.That is, the intensity of head unit 200 not only display unlike the prior art, the service that also user can be able to be utilized and the AP state of this machine are shown to user.In addition, if user selects in the service catalogue shown one or select AP state, then implement request to user's terminal 100 service of transmitting of correspondence or connection request performs the service selected, or be connected with this user's terminal.
Describe head unit 200 in above-mentioned and may implement the service information request of Wi-Fi and AP status request is together included in the project of probe requests thereby packet and transmits this probe requests thereby packet, and receive the probe response packet comprising service name and AP state information, but in this situation, also can without the need to comprising all information in the specification of probe requests thereby packet or probe response packet.Accordingly, head unit 200 is distinguished the service information request may implementing Wi-Fi and is transmitted individually with AP status request, and also receives service name and the AP state information of correspondence respectively separably.
Fig. 5 illustrates the example according to the picture based on showing when Wi-Fi connection header unit and portable machine of the present invention.Fig. 6 illustrates the example when selecting service at the picture of head unit display.
Fig. 5 is a simple example, and the signal strength signal intensity showing head unit 200 and prior art together shows the formation of the Wi-Fi service name that may provide to user.When comparing with Fig. 1, user can the service that can provide of each user's terminal 100 of visual confirmation, is therefore easy to select specific user's terminal.Moreover, user selects special services as shown in Figure 6, and then makes this service namely be shown in head unit 200 without the need to other setting, the service ease of use maximization that therefore can will use.
