Abstract

A data processing method applied to an electronic device is provided. The data processing method includes: establishing, by a first transceiver of a first electronic device; a first wireless connection with a second electronic device; positioning the second electronic device based on the first wireless connection, so as to obtain position information of the second electronic device; adjusting a transmission parameter of a second transceiver of the first electronic device to transmit a second wireless signal, so that the second transceiver transmits the second wireless signal to the second electronic device in a predetermined way; and establishing a second wireless connection with the second electronic device by the first electronic device based on the second wireless signal, a type of the second wireless connection being different from that of the first wireless connection.

Claims

1. A data processing method applied to a first electronic device, comprising:

performing a first identity authentication for a first wireless connection with a second electronic device bidirectionally or unidirectionally after a first transceiver of the first electronic device detects an access request transmitted by the second electronic device;

transmitting a first wireless signal and establishing, by the first transceiver of the first electronic device, the first wireless connection with the second electronic device based on the first wireless signal when the first identity authentication is successful;

positioning the second electronic device based on the first wireless connection, so as to obtain position information of the second electronic device;

performing a second identity authentication for a second wireless connection with the second electronic device based on the first wireless connection;

when the second identity authentication is successful, determining, based on the position information of the second electronic device, a transmission power and a transmission direction of a second transceiver of the first electronic device to transmit a second wireless signal, wherein the second wireless signal propagates a limited distance along an azimuth angle of the second electronic device relative to the first electronic device, the transmission power of the second transceiver of the first electronic device is determined to be enough to cover the second electronic device, the transmission power of the second wireless signal is less than a maximum transmission power of the second transceiver, a maximum transmission power of the first transceiver is less than the maximum transmission power of the second transceiver, and a maximum coverage area of the first transceiver is less than a maximum coverage area of the second transceiver; and

establishing the second wireless connection with the second electronic device by the first electronic device based on the second wireless signal to enable the second electronic device to perform a network access by the second wireless connection,

wherein the first electronic device comprises a wireless router, the first wireless connection comprises a point-to-point Bluetooth connection, the second electronic device comprises a user terminal, and the second wireless connection comprises a WiFi connection.

2. The data processing method of claim 1, wherein a signal transmitting and/or receiving mechanism of the first transceiver is different from that of the second transceiver.

3. The data processing method of claim 1, wherein the performing an identity authentication with a second electronic device bidirectionally or unidirectionally comprises:

authenticating an identity of the second electronic device, wherein the identity authentication is successful when the identity of the second electronic device is authenticated;

or

transmitting identification information of the first electronic device to the second electronic device, wherein the second electronic device authenticates an identity of the first electronic device based on the identification information of the first electronic device, and the identity authentication is successful when the identity of the first electronic device is authenticated.

4. The data processing method of claim 3, wherein after the first wireless connection is established, the method further comprises:

authenticating, by the first electronic device, the identity of the second electronic device for the second wireless connection based on the first wireless connection; and

adjusting the transmission power and the transmission direction of the second transceiver to transmit the second wireless signal after the identity of the second electronic device is authenticated, so that the second wireless signal propagates along an azimuth angle of the second electronic device relative to the first electronic device, and covers the second electronic device.

5. An electronic device having a first transceiver and a second transceiver, comprising:

a processor, and

a memory storing instructions, wherein the instructions when executed by the processor cause the processor to;

perform a first identity authentication for a first wireless connection with a second electronic device bidirectionally or unidirectionally after the first transceiver detects an access request transmitted by the second electronic device;

control the first transceiver to transmit the first wireless signal, and establish a first wireless connection with the second electronic device based on the first wireless signal when the first identity authentication is successful;

position the second electronic device based on the first wireless connection, so as to obtain position information of the second electronic device;

perform a second identity authentication for a second wireless connection with the second electronic device based on the first wireless connection;

when the second identity authentication is successful, determine, based on the position information of the second electronic device, a transmission power and a transmission direction of the second transceiver transmitting a second wireless signal, so that the second wireless signal propagates a limited distance along an azimuth angle of the second electronic device relative to the electronic device, and covers the second electronic device, wherein the determined transmission power of the second transceiver is less than a maximum transmission power of the second transceiver, as long as the determined transmission power of the second transceiver is able to make the second wireless signal cover the second electronic device, a maximum transmission power of the first transceiver is less than the maximum transmission power of the second transceiver, and a maximum coverage area of the first transceiver is less than a maximum coverage area of the second transceiver; and

control the second transceiver to transmit the second wireless signal, and establish the second wireless connection with the second electronic device based on the second wireless signal to enable the second electronic device to perform a network access by the second wireless connection,

wherein the electronic device comprises a wireless router, the first wireless connection comprises a point-to-point Bluetooth connection, the second electronic device comprises a user terminal, and the second wireless connection comprises a WiFi connection.

6. The electronic device of claim 5, wherein a signal transmitting and/or receiving mechanism of the first transceiver is different from that of the second transceiver.

7. The electronic device of claim 5, wherein the processor is configured to authenticate an identity of the second electronic device after detecting an access request transmitted by the second electronic device, and wherein the identity authentication is successful when the identity of the second electronic device is authenticated;

or

the processor is further configured to control the first transceiver to transmit identification information of the electronic device to the second electronic device after detecting an access request transmitted by the second electronic device, wherein the second electronic device authenticates an identity of the electronic device based on the identification information of the electronic device, and wherein the identity authentication is successful when the identity of the electronic device is authenticated.

8. The electronic device of claim 7, wherein the processor is further configured to:
