Please refer to fig. 1, which is a flowchart illustrating a wireless communication method based on location information according to the present invention. As shown in fig. 1, the establishing method includes the following steps:
s10, the sending terminal and the receiving terminal are accessed to a wireless AP, and the sending terminal acquires the receiving position information of the receiving terminal.
S20, the sending terminal judges whether the direct connection can be achieved according to the position information and the transmission rate: if so, the sending terminal and the receiving terminal are switched to a direct connection transmission mode to transmit data, otherwise, the wireless AP transmission mode is kept.
In step S10, two terminals that need to perform data transmission access the same wireless AP, thereby entering the wireless AP transmission mode. Based on the fact that the transmission is bidirectional, the terminal that transmits data first is set as the transmitting terminal, and the other terminal is set as the receiving terminal. The sending terminal and the receiving terminal are both accessed to the same wireless AP, and the wireless AP may be a simple wireless access point (i.e. a wireless switch), or may be a generic term of devices such as a wireless router (including a wireless gateway and a wireless bridge). Before formal data transmission, corresponding instructions and authentication are transmitted between the sending terminal and the receiving terminal through the wireless AP. It should be understood that the transmitting terminal and the receiving terminal are not fixed, and the terminal that transmits data is referred to as the transmitting terminal, and the terminal that receives data is referred to as the receiving terminal.
The sending terminal and the receiving terminal in the embodiment have a function of acquiring data of three axes (an X axis, a Y axis and a Z axis), wherein the X axis and the Y axis are acquired through the existing GPS or AGPS scheme, and the two terminals are internally provided with corresponding GPS chips, namely the current position coordinates of the X axis and the Y axis can be acquired; the Z-axis coordinates can be obtained by the barometer (the manufacturer of the barometer has an internal algorithm, and the barometer can calculate the current Z-axis coordinates, which is a prior art), and in the specific implementation, other modules can be used to obtain the three-axis coordinates, which is not limited herein. Before wireless data transmission, the two terminals send position acquisition commands by the sending terminal and transmit the position acquisition commands to the receiving terminal through the wireless AP, and the receiving terminal acquires physical position coordinates of the receiving terminal according to the position acquisition commands and transmits corresponding receiving position information (X1, Y1 and Z1) to the sending terminal through the wireless AP.
In step S20, the step of determining, by the sending terminal, whether direct connection is possible according to the location information specifically includes:
and step 21, the transmitting terminal calculates the distance between the transmitting terminal and the receiving terminal according to the position information and the receiving position information of the transmitting terminal.
The sending terminal acquires the position information (X2, Y2, Z2) of the sending terminal, and the distance d between the sending terminal and the receiving terminal can be calculated by combining the receiving position information (X1, Y1, Z1), and the formula is as follows:
. In this embodiment, the distance between two points in the three-dimensional space is used to determine whether the position satisfies the direct connection, and in specific implementation, the distance may also be determined in other manners, such as longitude and latitude.
And step 22, testing the transmission rate of the transmitting terminal and the receiving terminal through the wireless AP.
In this step, the transmission rate is tested in a packet filling manner, which is the prior art, for example, in this embodiment, the sending terminal performs file transmission by using a test file to pretest the transmission rate between two terminals.
And step 23, the sending terminal judges whether the distance is smaller than a threshold value and the direct connection speed is larger than the transmission speed.
In this step, a distance smaller than a threshold (e.g., 5 m) indicates that the distance between the two terminals is short, and the two terminals may be in a wireless direct connection manner, such as WIFI direct connection, bluetooth direct connection, and the like; if the distance is long, the transmission power of the two terminals is limited, and the data transmission is affected. However, if the direct connection rate of the wireless direct connection mode is smaller than the transmission rate provided by the wireless AP, there is no need for direct connection. Thus, direct connection is only possible if the distance is less than a threshold and the rate of direct connection is greater than the transmission rate.
The sending terminal firstly judges whether the distance is smaller than a threshold value or not, does not need speed judgment if the distance is not smaller than the threshold value, and keeps the current wireless AP transmission mode; if the current wireless direct connection rate is less than the transmission rate of the wireless AP, acquiring the direct connection rate of the current wireless direct connection and judging whether the direct connection rate is greater than the transmission rate of the wireless AP or not; if the direct connection rate is greater than the transmission rate, authentication is carried out between the two terminals, the sending terminal sends an authentication password (token) to the receiving terminal, the receiving terminal returns an authentication password to the sending terminal, and the two terminals carry out mutual authentication through the authentication password so as to play a safety role and prevent the transmitted data from being stolen. After the tokens are sent each other, the two defaults have mutually approved a direct connection transmission mode (the default mode is WIFI direct connection), at the moment, the background of the wireless communication system of the two terminals detects whether WIFI is started or not, the WIFI is not automatically started, the sending terminal and the receiving terminal are connected through the WIFI, and data can be transmitted through the WIFI.
In this embodiment, mainly for data transmission, in step S10, after both the sending terminal and the receiving terminal access the same wireless AP, if the sending terminal needs to perform data transmission, the sending terminal will obtain the location information of the receiving terminal and execute step S20. When the data transmission is completed, the transmitting terminal and the receiving terminal can be restored to the state before the data transmission.
If the direct connection transmission mode is switched in step S20, after step S20, the wireless AP connection needs to be restored, that is, after the data transmission between the sending terminal and the receiving terminal is completed, the WIFI connection is disconnected, and the wireless AP is accessed, so that the wireless AP transmission mode is restored. If the wireless AP transmission mode is maintained in step S20, the processing is not performed, and the current transmission state is maintained.
Because the number of the users accessing is changed, the transmission rate of the wireless AP can be influenced, the positions of the two terminals can also be changed, and the wireless AP transmission mode is recovered after the data transmission is finished, so that other working states when the wireless AP is connected can be avoided being influenced, whether the direct-connection rate is greater than the current transmission rate of the wireless AP or not can be accurately judged, the data needs to be transmitted next time, the sending terminal can obtain the position information of the receiving terminal again and execute the step S20, and whether the transmission mode needs to be switched or not is judged again.
Referring to fig. 2, the present embodiment discloses a wireless communication system based on the above wireless communication method based on location information, the wireless communication system includes a transmitting terminal 100, a receiving terminal 200 and a wireless AP 300, the transmitting terminal 100 and the receiving terminal 200 access to the wireless AP 300, and the transmitting terminal 100 obtains location information of the receiving terminal 200; the sending terminal judges whether the direct connection can be achieved according to the position information and the transmission rate: if so, the sending terminal and the receiving terminal are switched to a direct connection transmission mode to transmit data, otherwise, the wireless AP transmission mode is kept. The terminal can be a mobile phone, a tablet personal computer, a desktop computer and the like, has a three-axis (X-axis, Y-axis and Z-axis) data acquisition function and can be in wireless connection with terminal equipment.
In summary, in the wireless communication method and the wireless communication system thereof based on the location information provided by the present invention, two terminals access the same wireless AP, when data needs to be transmitted, the actual distance between the two terminals is calculated by obtaining the location information of the two terminals, the distance between the terminals is used for transmission measurement, when the distance is smaller than the threshold and the direct connection rate is greater than the transmission rate of the wireless AP, the condition of performing wireless direct connection is satisfied, the two terminals mutually transmit a token for authentication, switch to the direct connection mode with a faster rate and transmit a file, the direct connection rate is significantly higher than the wireless lan rate, there is no route path restriction, and no restriction on the transmission capability of the wireless AP, and the file transmission rate is increased; if the direct connection condition is not met, the current wireless AP transmission is kept, the connection efficiency is ensured, and an optimal data transmission mode is ensured to be provided for the user all the time.
