Communication terminal and method for playing ringback sound while its main calling

Abstract

The present invention discloses communication terminal and playing ringing back tone method in calling, to make calling user capable of to customize personalized ringing back tone, referring to communication technology. The present invention utilizes communication terminal to oneself sound track switching ability and playing local ringing ability closing speech-sounds channel in calling originating for preventing playing network side ringing back tone' in calling procedure playing local predetermined ringing until called terminal beginning listening or calling overtime, then reopening speech-sounds channel to make calling terminal communication with called terminal or network side informing calling terminal cue tone that the opposing side unable listening. Said invention presets local ringing respectively to different calling number or group, to make calling terminal not only capable of configuring required ringing back tone by itself, but also hearing different ringing back tone in calling different user.

Description

technical field [0001] The invention relates to the communication technology, in particular to the technology for the communication terminal to play the ring-back tone when calling. Background technique [0002] Today, with the rapid development of telecommunication technology, as users' needs are increasingly diversified and personalized, new items are constantly appearing in the mobile value-added services of mobile phones and fixed phones to meet the increasingly rich and personalized needs of mobile users. For example, multimedia message services (Multimedia Message Services, "MMS" for short), Interactive Voice Response (Interactive Voice Response, "IVR" for short), voice short messages, etc. appear in mobile phone value-added services. So the personalized ring back tone service came into being. Ringback tone is a signal tone. In communication, the calling user initiates a call to the called UE through a wired or wireless telephone user terminal (User Equipment, referre...

Problems solved by technology

[0004] In practical applications, the above-mentioned scheme has the following problems: the playing effect of the ring back tone is sometimes good and sometimes not good, the ring back tone types and quantities that the user can choose are very limited, and the ring back tone heard by the calling user cannot be determined according to the individual According to preferences, you can only be forced to listen to the ring back tone customized by the called user, and the called user needs to pay for the ring back tone function, which increases the additional burden on the called user

[0005] The main reason for this situation is that the existing ring back tone is played through the network, and the playback effect is unstable due to the limitation of the network conditions during the playing process, and the ring back tone business industry is highly concentrated. , many outlets have not yet established a sound product development and innovation mechanism, so the CRBT resources are not rich enough, and the personalization and differentiation are insufficient, resulting in a high degree of repetition of CRBT among various outlets; and because the CRBT function is provided by telecom service providers, users can choose The ring back tone is limited by the type and number of ring tones provided by the service provider

Moreover, the existing CRBT technology is mainly a service for the called user, and the calling user cannot select the ring-back tone heard by himself according to his personal preferences, but can only listen to the ring-back tone customized by the called user; Due to the service provided by the telecommunications service provider, it is necessary to pay for the service, which increases the additional burden of the called user
