Mobile terminal, conference server and conference control method

Abstract

The invention provides a mobile terminal which comprises a terminal transmitting unit, a terminal receiving unit, a voice frequency recording unit and a processing unit. The terminal transmitting unit transmits a conference request to a conference server and transmits a conference control request to the conference server in double-voice multi-frequency mode. The terminal receiving unit receives short message information from the conference server when a conference begins and double-voice multi-frequency signals and voice frequency signals from the conference server in the conference process. The short message information includes serial number information and initial state information of a conference participating terminal. The double-voice multi-frequency signals comprises state change information of the conference participating terminal. The voice frequency recording unit records received double-voice multi-frequency signals and voice frequency data. The processing unit is used for conducting voice frequency spectral analysis on recorded data, filter the double-voice multi-frequency signals and show the signals to a user of the mobile terminal. Correspondingly, the conference server and a conference control method are further provided. By means of the technical scheme, the information interaction in the conference process can be conducted in the short message and double-voice multi-frequency combination mode.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular, to a mobile terminal, a conference server and a conference control method. Background technique [0002] There are three main types of conference calls: [0003] In the traditional conference system, each terminal can reserve and join a conference through the access number and password provided by the conference service provider. This form of conference does not require any software to be installed on smartphones, and mobile phones and ordinary landlines can be connected in the same way. Similarly, smartphones do not have any advantages in this kind of conferencing system. [0004] VOIP conference system, each terminal is connected through the Internet. The smart phone needs to install the corresponding VOIP phone client, the user can book a conference, initiate a conference; the initiator can control the conference. During the meeting, the smart phone is equivalent t...

Problems solved by technology

But for CDMA (Code Division Multiple Access, code division multiple access) network and GSM network, once the voice call is established, the mobile phone data service will be cut off, and the two cannot coexist

Therefore, conference control based on data services has too many limitations. China Mobile and China Telecom users cannot use this conference control function when their mobile phones do not have WIFI access, which is of little practical significance in China.

[0008] The SMS-based conference control scheme can bypass the dependence of the data-based business scheme on the network standard, but the SMS method also has the following defects and shortcomings: SMS is unreliable transmission, real-time performance is not strong, and there will be a certain delay

In addition, the SMS method will have additional economic expenses. During a meeting, SMS is completely used for conference control interaction, and dozens or even hundreds of SMS messages will be generated.
