EXAMPLE III
In this embodiment, the user identification method provided in the embodiment of the present invention is described through a specific scenario by taking an identified user as a super user as an example. Here, the client corresponds to the first electronic device in the first embodiment, and the wireless access point corresponds to the second electronic device in the second embodiment.
The distance between a mobile Wi-Fi client (Station, STA) and a Wi-Fi wireless Access Point (Access Point, AP) can be positioned through the FTM protocol. The position of one Wi-Fi AP is fixed, and if the STA obtains the distance information with at least three APs, the self position information can be calculated by a triangulation method. A low-performance STA may also acquire only range data and hand off the computational tasks to a higher-performance device, such as a high-performance location computation server.
The FTM protocol is generally initiated by the mobile equipment, is responded by the Wi-Fi AP, and can initiate an FTM protocol request message with the corresponding AP to perform protocol interaction regardless of whether the mobile equipment is connected with the corresponding AP or not.
The basic flow of protocol interaction between a Wi-Fi STA and a Wi-Fi AP is shown in FIG. 3:
step 301, a mobile client initiates an FTM request;
step 302, the Wi-Fi AP initiates the first FTM Action Frame interaction, the session identifier is n, and the last session identifier is 0, which indicates that the last session is not associated. Through the interaction of the Action frame and the ACK frame, the AP records two times t1 and t4, which are the time of sending the Action frame and the time of receiving the ACK frame, respectively. The mobile client records two times t2 and t3, wherein the distribution is the time of receiving an Action frame and the time of sending an ACK frame;
step 303, the FTM Action Frame interaction for the second time, the Wi-Fi AP sending the information of t1 and t4 to the mobile client. The distance between the mobile client and the AP can be calculated through formulas (1) and (2), and the distance between the mobile client and the Wi-Fi AP can be calculated through multiplying the light speed by the time difference.
ToF＝[(t4-t1)-(t3-t2)]Formula/2 (1)
Range ═ C ToF formula (2)
Wherein, ToA is Time of arrival (ToA) of the message; ToD is Time of departure (ToD) of the message; ToF is time difference (ToF); c is the Speed of light (Speed of light, C).
Then, by the distance of at least three Wi-Fi APs, the specific position information of the mobile device can be calculated through triangulation, as shown in FIG. 4. Three APs are included in fig. 4: AP1, AP2, AP3, and the mobile device UE is located among AP1, AP2 and AP3, and the position information of the UE is obtained through calculation according to the distance between AP1 and the UE, the distance between AP2 and the UE, and the distance between AP3 and the UE.
The FTM Action Frame contains the following information as shown in fig. 5.
Wherein, the FTM Action Frame comprises a FTM parameter part with a non-fixed length: in the Fine timing measurement Parameter, the field definition of the FTM Parameter part is shown in fig. 6, two bits, B48 and B49, are reserved fields, and this reserved field is used to carry super-user information in the embodiment of the present invention, and the relevant definition is shown in table 1:
table 1 user information definition example
B48 Bit value B49 Bit value Definition of
0 0 General customers
0 1 Copper card client
1 0 Bank card client
1 1 Gold medal client
The embodiment of the invention simultaneously extends and defines an FTM parameter Element which is used for carrying the identifications of merchants and users, and can be defined as the following form:
Element ID Lenght merchant or user identification
1 1 Variable-length character string
If the message is sent from the merchant Wi-Fi AP to the mobile client, the carried message is a merchant identification character string, and if the message is sent from the mobile client to the merchant Wi-Fi AP, the carried message is a user identification, such as: a cell phone number.
Figure BDA0001802667380000111
The user corresponding to the embodiment of the present invention may install APP of the merchant, or pay attention to applications such as public numbers of the merchant, and these applications of the merchant may extract priority and ID identification information of the user, for example: and the mobile phone number sets the message information field of the Wi-Filocation. The merchant Wi-Fi AP will default to merchant information, such as that of China Mobile, which can be identified by the string "CMCC".
The method of the embodiment of the invention mainly comprises the following steps as shown in figure 7:
step 701, a customer enters an offline physical store of a merchant;
step 702, a Wi-Fi router of a merchant defaults to carry merchant identification information in a Wi-Fi Location message interacted with a mobile client, for example, China mobile can be a character string CMCC;
step 703, the user is a merchant user, and receives the user with the merchant identifier such as: the Wi-Fi Location message of the CMCC confirms that the business circle is entered;
step 704, the mobile client of the user encodes the ID information and the priority information into a Wi-Fi Location message;
step 705, the mobile client of the user sends a Wi-Filocation message carrying the user identifier and the user priority information to the AP of the merchant;
step 706, while the information interaction is performed, the Wi-Fi Location also completes the positioning process, and the merchant AP knows the indoor positioning information of the mobile client;
step 707, the Wi-Fi router reports the obtained user position information to a background management system;
step 708, the background User management system presents the User level information and the corresponding position to the employee in real time through a User Interface (UI), and notifies nearby employees to perform customer care and customer service to the super User in time.
The embodiment of the invention also provides a method for entering a business district of a corresponding merchant by the mobile client through Wi-Fi Aware sensing, and then the merchant carries the user information based on the Wi-Fi multicast message of the mobile client, so that the super-level user can be quickly identified, and the enterprise can be helped to improve the user service experience.
The Wi-Fi Aware peripheral perception technology can send extremely small data information to help various applications to realize a service discovery function. Compared with the common Wi-Fi application, the application has lower energy consumption, so the application can continuously run in the background of the device, once the corresponding service or application is discovered and is harmonious with other devices, the Wi-Fi Direct or the conventional Wi-Fi connection can be carried out, and after the service is discovered, a user can 'select' to establish connection with the discovered device without using the Internet connection. In short, Wi-Fi Aware can help users quickly learn about nearby services of interest.
Neighbor Awareness Networking (NAN) clustering in Wi-Fi Aware, as shown in FIG. 8. The NAN Cluster includes several NAN devices, which adopt the same NAN configuration parameters to synchronize information between the devices. One NAN Device may send a multicast NAN Service Discovery frame to all other devices in the NAN cluster, or may directly send a unicast NAN Service Discovery frame to any other devices to discover a Service of interest.
If a NAN Device supports both the basic Wi-Fi and Wi-Fi Aware functions, it can join two networks at the same time, as shown in fig. 9, and it is necessary that the NAN Device has two MAC addresses. If the existing Wi-Fi equipment needs to be upgraded to support Wi-Fi Aware, hardware does not need to be upgraded, and only Wi-Fi driving software needs to be upgraded to support Wi-Fi Aware.
Wi-Fi STAs have two modes of accessing the AP, and the two modes are active scanning and passive scanning. Active scanning is that the STA actively sends a Wi-Fi Probe Request (Probe Request) message to search for a nearby AP hotspot. The AP replies with a probe response (ProbeResponse). The passive scanning is that the AP periodically sends a Beacon (Beacon) message to show its own Service Set Identifier (SSID), and the content of the Beacon message is substantially consistent with the Probe Response.
The invention realizes the function that the mobile terminal of a user automatically senses entering a business district of a merchant based on a Wi-Fi Aware NAN network, a NAN Service Discovery protocol exchanges Service information provided by equipment through a NAN Service Discovery Frame (SDF), and the NAN Service Discovery protocol provides two message types: publish message and subscribe message.
