Problems solved by technology

[0003] However, not all call parties can meet the conditions for using data services, especially on the existing mobile communication network, the Code Division Multiple Access (CDMA, Code Division Multiple Access) network of China Telecom cannot make calls Simultaneous use of data services
For the ordinary call process in such a data-free service environment, at present, there is no relevant technical solution for how to realize efficient and intuitive calls

Embodiment Construction

[0046] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] A mobile terminal implementing various embodiments of the present invention will now be described with reference to the accompanying drawings. In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating description of the present invention and has no specific meaning by itself. Therefore, "module" and "component" may be used mixedly.

[0048] Mobile terminals may be implemented in various forms. For example, terminals described in the present invention may include devices such as mobile phones, smart phones, notebook computers, digital broadcast receivers, PDAs (Personal Digital Assistants), PADs (Tablet Computers), PMPs (Portable Multimedia Players), navigation devices, etc. mobile terminals and fixed terminals such as digital TVs, desktop c...

Abstract

The invention discloses a method for realizing voice call. A sender draws a pattern in a preset area, encodes the scanned information of all the pixels or pixel change lines in the area into binary data, modulates the binary data into audio signals of two frequencies through binary frequency shift keying, and finally, transmits the audio signals to an opposite terminal through an ordinary voice call channel; and the opposite terminal performs decoding, and redisplays the pattern drawn by the sender in the preset area. In addition, the invention discloses a device for realizing voice call. Through the technical scheme of the invention, efficient and visual call is achieved based on an ordinary call process in an environment without data service.

Description

technical field [0001] The present invention relates to the technical field of voice calls, in particular to a method and device for realizing voice calls. Background technique [0002] At this stage, mobile terminals have become popular, and two people who do not know each other can communicate easily. However, the vast majority of users are still at the stage of voice calls. However, some things cannot be expressed efficiently and intuitively through voice communication. In this case, a real-time electronic whiteboard can be established during the call, so that both parties can make a brief description on the electronic whiteboard. Let the other party understand the meaning more clearly. This method of achieving efficient and intuitive communication by establishing a real-time electronic whiteboard is easy to implement in the existing data environment based on the Internet. [0003] However, not all call parties can meet the conditions for using data services, especiall...
