Abstract

Disclosed are an information interaction method and apparatus, and an electronic device. A specific implementation of the method comprises: acquiring a first near-field communication signal; extracting, from the first near-field communication signal, first pairing information for pairing with a multimedia conference terminal; and sending the first pairing information to a server, so as to instruct the server to determine a target multimedia conference terminal on the basis of the first pairing information and to establish a communication connection between the target multimedia conference terminal and a user terminal device. By means of the implementation, the convenience for a user to control a multimedia conference terminal is improved. In addition, the overall cost of a multimedia conference system can be reduced.

First claim

The invention claimed is:

1 . An information interaction method, comprising:
acquiring a first near-field communication signal; extracting first pairing information, for pairing with a multimedia conference terminal, from the first near-field communication signal; and sending the first pairing information to a server, to instruct the server to determine a target multimedia conference terminal based on the first pairing information and establish a communication connection between the target multimedia conference terminal and a user terminal, wherein the first near-field communication signal comprises an ultrasonic signal sent from the multimedia conference terminal, the ultrasonic signal comprises the first pairing information generated by the multimedia conference terminal based on second pairing information, the second pairing information is sent from the server to the multimedia conference terminal in advance, and wherein the sending the first pairing information to a server, to instruct the server to determine a target multimedia conference terminal based on the first pairing information and establish a communication connection between the target multimedia conference terminal and a user terminal comprises: sending the first pairing information extracted from the ultrasonic signal to the server, to instruct the server to determine the target multimedia conference terminal based on the first pairing information and the second pairing information and establish the communication connection between the target multimedia conference terminal and the user terminal.

2 . The method according to claim 1 , wherein the first near-field communication signal further comprises at least one of a Bluetooth signal sent from the multimedia conference terminal or a Wi-Fi signal of a network environment.

3 . The method according to claim 2 , wherein the first near-field communication signal comprises the Bluetooth signal sent from the multimedia conference terminal, and
before extracting the first pairing information, for pairing with the multimedia conference terminal, from the first near-field communication signal, the method further comprises: determining a distance between the user terminal and the multimedia conference terminal based on the Bluetooth signal; determining, based on the distance, whether the multimedia conference terminal and the user terminal are located in a same conference room; and extracting the first pairing information from the Bluetooth signal in response to determining, based on the distance, that the multimedia conference terminal and the user terminal are located in a same conference room, wherein the first pairing information comprises identity information of the multimedia conference terminal.

4 . The method according to claim 2 , wherein the first near-field communication signal comprises the Wi-Fi signal, and
the extracting first pairing information, for pairing with a multimedia conference terminal, from the first near-field communication signal comprises: extracting identity information of a Wi-Fi device comprised in the Wi-Fi signal, and generating the first pairing information based on the identity information; and the sending the first pairing information to a server, to instruct the server to determine a target multimedia conference terminal based on the first pairing information and establish a communication connection between the target multimedia conference terminal and a user terminal comprises: sending the first pairing information to the server, to instruct the server to determine the target multimedia conference terminal based on the identity information of the Wi-Fi device in the first pairing information and the identity information of the Wi-Fi device in a network environment where a plurality of multimedia conference terminals are located.

5 . The method according to claim 1 , wherein the acquiring a first near-field communication signal comprises:
receiving the ultrasonic signal with an audio receiver.

6 . The method according to claim 1 , wherein after sending the first pairing information to the server and successfully establishing the communication connection between the target multimedia conference terminal and the user terminal, the method further comprises:
continuously acquiring a second near-field communication signal at a preset time interval, wherein the second near-field communication signal is sent from the target multimedia conference terminal to the user terminal; and sending the second near-field communication signal to the server, wherein the server determines whether to keep the communication connection based on the second near-field communication signal.

7 . The method according to claim 1 , further comprising:
performing, according to an operating instruction of a user, at least one of following operations through the communication connection: an operation of entering or exiting a multimedia conference, an operation of adjusting a preset parameter of the multimedia conference, and an operation of performing a preset process on meeting content.

8 . The method according to claim 1 , wherein the method is applied to the user terminal.

9 . An information interaction method, comprising:
receiving first pairing information for pairing sent from a user terminal, wherein the first pairing information is extracted by the user terminal and extracted from a first near-field communication signal acquired by the user terminal; matching the first pairing information with information of a multimedia conference terminal; determining a target multimedia conference terminal based on a result of the matching; and establishing a communication connection between the target multimedia conference terminal and the user terminal, wherein the first near-field communication signal comprises an ultrasonic signal sent from the multimedia conference terminal, the ultrasonic signal comprises the first pairing information generated by the multimedia conference terminal based on second pairing information, the second pairing information is sent to the multimedia conference terminal in advance, and wherein determining the target multimedia conference terminal and establishing the communication connection between the target multimedia conference terminal and the user terminal comprises: receiving the first pairing information extracted from the ultrasonic signal, determining the target multimedia conference terminal based on the first pairing information and the second pairing information, and establishing the communication connection between the target multimedia conference terminal and the user terminal.

10 . The method according to claim 9 , wherein the first near-field communication signal further comprises at least one of a Bluetooth signal sent from the multimedia conference terminal or a Wi-Fi signal of a network environment.

11 . The method according to claim 10 , wherein the first pairing information comprises identity information of the multimedia conference terminal, and the identity information of the multimedia conference terminal is determined by the user terminal based on the Bluetooth signal sent from a Bluetooth device of the multimedia conference terminal, and
the matching the first pairing information with information of a multimedia conference terminal comprises: matching the identity information of the multimedia conference terminal in the first pairing information with identity information corresponding to each of a plurality of candidate multimedia conference terminals.

12 . The method according to claim 10 , wherein the first pairing information comprises identity information of a Wi
