Description

Method and terminal for determining ring back tone of calling terminal by called terminal

Technical Field

The present invention relates to the field of network communication technologies, and in particular, to a method and a terminal for playing a ring back tone for a calling terminal.

Background

In the process of telephone calling, after a calling terminal dials, a terminal of a called terminal starts ringing after receiving a calling request so as to remind a user to pick up the phone, and simultaneously, the terminal of the calling terminal starts playing a ring back tone so as to inform the calling terminal that a line is connected and the terminal of the called terminal is playing the ring back tone.

Currently, a ring back tone of a PSTN (Public Switched Telephone Network) Telephone is sent by a local side device where a called terminal is located, that is, the local side device where the called terminal is located sends the ring back tone to a calling terminal, so that the calling terminal plays a corresponding ring back tone. Generally, a corresponding ringback tone is set as a fixed long sound, and the playing process of the corresponding ringback tone includes: after the calling party dials, the called party office receives the calling request, and the ring back tone is played to the calling party while the called party is informed of the ringing.

When the called terminal receives the call request, it obtains the identification information of the calling terminal (such as the number of the calling terminal), and then searches the corresponding ring back tone information according to the identification information of the calling terminal, thus determining the ring back tone information selected for the calling terminal;

the method is as follows: the called terminal selects a specified type of ringback tone information. The called terminal may select a specified one of the ringback tone information. For example, the user may specify the ring back tone information played for the calling terminal at the current stage at any time according to the requirement, so that the called terminal only needs to send the ring back tone information specified by the user to the calling terminal after the user receives the call request.

In the embodiment of the invention, the ring back tone information is stored on the terminal of the called terminal and is transmitted to the calling terminal after receiving the call request, so that the calling terminal can hear the ring back tone information set by the called terminal. Thus, the user can conveniently and quickly set the ring back tone, thereby well meeting the personalized requirements of the user, for example, the user can set the ring back tone information for informing the current state of the called terminal, or the user can set the specific ring back tone information for the specific calling terminal, and the like.
