In a wireless handset 20 system, the host 10 may generally be a relatively difficult-to-move terminal device (e.g., smart tv, desktop computer), and the handset 20 may be mobile and flexible within the application scenarios of the wireless handset 20 system.

the signal detection module 103 is in communication connection with the signal receiving module 102 and is used for continuously scanning and detecting wireless signal connection, receiving and analyzing data packets of the wireless signals received by each directional antenna and extracting wireless connection parameters; the wireless connection parameters include device information and wireless signal frequency of each router hotspot 40, and signal strength and direction of WiFi connection between the second WiFi module of the host 10 and each router hotspot 40, and are all stored in a memory in communication connection with the processor for the processor to analyze WiFi connection status.

In order to facilitate the calculation of direction finding of a plurality of high-gain directional antennas, the directional antennas are arranged in the same plane, one ends of the directional antennas are gathered on the same circle center and are radially arranged towards the periphery, namely the directional antennas are radially arranged in the same circle, the end parts of the directional antennas are converged at the circle center of the same circle, and the track connecting lines formed by connecting the other ends of the directional antennas, which are deviated from the circle center, form an arc. Therefore, all the directional antennas form a sensing surface with uniform signal sensitivity, when the same signal passes through the sensing surface, the time point and the signal intensity of the signal detected by the directional antennas at different positions are different, and the forward time point is closer to the signal source, the directional antenna with the larger signal intensity is closer to the signal source, so that the signal source direction is reversely deduced.

Preferably, the number of the directional antennas is 4n, and n is a natural number; the spacing angles of the directional antennas are the same, as shown in fig. 5, the arrows in fig. 5 are the directional antennas, so that the directional antennas are more favorably configured into a uniform circle and the subsequent direction calculation is facilitated, for example, the number of the directional antennas is 4, 8, 16, 32, and the like, so that the circular plane is uniformly divided by the plurality of directional antennas.

The signal receiving module 102 is composed of receiving terminals having the same number as the number of directional antennas in the antenna module 101, and each directional antenna in the antenna module 101 is connected to an independent receiving terminal in the signal receiving module 102 one-to-one. Each receiving end sends the signal to the signal detection module 103, as shown in fig. 4.

And the signal detection module 103 is connected with the signal receiving module 102 and used for continuously scanning and detecting wireless signal connection, receiving and analyzing data packets of wireless signals received by each directional antenna, extracting wireless connection parameters, wherein the wireless connection parameters comprise equipment information and wireless signal frequency of each WiFi Direct connection router hotspot 40 and signal strength and direction of each WiFi Direct connection, and the wireless connection parameters are stored in a memory to be used for a processor to analyze the WiFi connection state of the host 10 and are stored in the memory.

The signal detection module 103 can calculate, by using the antenna module 101 and the signal receiving module 102, the reception strength values of the wireless signals sent by the same signal source on the plurality of directional antennas, and the signal strength and direction changes of each network connection, and can perform quick direction finding under the condition of signal discontinuity or signal discontinuity in digital communication.

The signal detection module 103 mainly uses a 2-division method to determine, according to the signal strength, the direction of the directional antenna capable of receiving the stronger signal by an equal division, and the direction between the two directional antennas with stronger signals is the incoming wave direction of the relatively more accurate signal.

In this embodiment, the host 10 can perform relatively accurate direction finding in a weak and rapidly changing wireless signal environment based on the WiFi connection state detection module, which is a technical effect that a single directional antenna cannot achieve, and timely knows that the host 10 prepares to establish WiFi Direct connection or changes the position and direction of the router hotspot 40 that has already established WiFi Direct connection.

Optionally, the processor of the host 10 further includes:

the matching module 104 is in communication connection with the signal detection module 103 and the memory, and is configured to acquire the detected and extracted wireless connection parameters from the signal detection module 103, and match the wireless connection parameters with standard connection parameters prestored in the host 10 to determine whether the current WiFi connection state of the second WiFi module is abnormal in network connection;

WiFi connection status detection module still includes:

and the prompting module 105 is in communication connection with the matching module 104 in the processor and is used for prompting the network connection abnormity, and the prompt output by the prompting module 105 can be prompted in various modes such as sound, image, text and the like.

For example, as shown in fig. 6, assuming that the router hotspot 402 is an illegal end, the device information of the router hotspot 402 is set to be consistent with the router 21, including an encryption mode, a MAC address, a device name, and the like. Because the device information of the router hotspot 401 is consistent with that of the router hotspot 402, the host 10 establishing WiFi Direct connection cannot distinguish, and the router hotspot 402 can provide service at a closer distance from the host 10 (the provided signal is stronger), so that the host 10 can easily perform data interaction through the router hotspot 402, which causes some unsafe factors. And through increasing wiFi connection status detection module in this application host computer 10 and detecting, if under the equipment information and the channel condition of same router hotspot 40, signal strength or signal direction take place the sudden change, then can judge that the router hotspot 40 connected with host computer 10 has taken place wireless connection and has switched, there is the possibility of illegal switching.

In the present application, through comparison of the wireless connection parameters, it is determined that the network connection possibly existing in the router hotspot 40 is abnormal, and then, it is determined that the illegal wireless connection possibly existing in the router hotspot 40 is abnormal.

Optionally, in another embodiment of the wireless phone 20 system of the present application, referring to fig. 7, the wireless phone 20 system further includes a registration server 70, and the host 10 is communicatively connected to the registration server 70; wherein,

the host 10 is further configured to receive and store the standard device information and the standard connection parameters sent by the registration server 70 in the memory, and detect whether the memory stores standard device information matching the device information of the connection phone 20 when the phone 20 performs WiFi Direct connection, and if there is no matched standard device information, the host 10 refuses to connect the connection phone 20;

the phone 20 is used for connecting the host 10 or the registration server 70;

the registry server 70 is configured to send the device information of the handset 20 to the host 10 as standard device information when the WiFi Direct connection is successfully established with the handset 20.

The specific steps of the wifi-direct connection between the phone 20 and the host 10 are as follows: first with the registration server 70 and then with the host 10. After the phone 20 is connected to the registration server 70, the host 10 can store the device information of the phone 20, and thus, the automatic connection of the phone 20 can be completed. Then handset 20 may make a wifi-direct connection directly with host 10 without having to make a connection with registry server 70.

When the host 10 and the phone 20 are in wifi-direct connection, whether the device information of the slave device side is stored is detected, and if not, the connection of the phone 20 is rejected or a connection request of the phone 20 of the user is prompted. Rejecting the connection of the handset 20 is suitable for a strict connection mechanism of the host 10, avoiding connection of the handset 20 that does not pass through the registration server 70, avoiding congestion of the network. The user may also be prompted for a connection request by phone 20 to allow the user to select whether to connect phone 20, thus facilitating connection of phone 20 without registration server 70.

The connection between registrar server 70 and handset 20 is a wifi encrypted connection, and handset 20 needs to input the correct registration key to successfully connect to registrar server 70. Only the phone 20 that knows the registration key can be successfully connected with the registration server 70, and the registration server 70 can acquire the device information of the phone 20, so that the host 10 can store the device information of the phone 20, and the phone 20 can be automatically connected with the host 10. And the handset 20 which does not input the correct registration key cannot connect with the registration server 70, thereby increasing the security of the registration server 70 by the registration key.

Optionally, the registration server 70 includes a first wireless network card 701 and a second wireless network card 702, the first wireless network card 701 works in a Soft-AP state, the phone 20 is connected to the registration server 70 through the first wireless network card 701, the second wireless network card 702 works in a state, and the host 10 is connected to the registration server 70 through the second wireless network card 702.

In order to implement the above scheme, the registration server 70 needs to have a wireless network card capable of connecting with the host computer 10 and the telephone 20. The registration server 70 may include a first wireless network card 701 and a second wireless network card 702 (as shown in fig. 7), the first wireless network card 701 works in a Soft-AP state, the phone 20 is connected to the registration server 70 through the first wireless network card 701, the second wireless network card 702 works in a state, and the host 10 is connected to the registration server 70 through the second wireless network card 702. In addition, in some embodiments, the registration server 70 may only include a wireless network card, and the wireless network card respectively operates in the Soft-AP state and the Station state. The Soft-AP state of the wireless network card can realize the connection with the phone 20, and the Station state of the wireless network card can realize the connection with the host 10, so that one wireless network card reduces the equipment investment of the system.

The Soft-AP state is a Soft AP state, and its hardware is a standard wireless network card, but it provides the same functions as AP, such as signal switching, routing, etc. through a driver. The Station state is a normal working state of the wireless network card under a general condition, and the wireless network card can be connected with a wireless router for internet communication.

In this embodiment, the host 10 can complete automatic connection of the wifi-direct of the phone 20, so that the connection pressure of the host 10 is greatly reduced, and network congestion is avoided.
