Call prompt method

A first terminal used in a Code Division Multiple Access (CDMA) communication network, comprising at least one processor, a transceiver, one or more memories, a display screen, an audio frequency circuit, and a bus;

• wherein:
• the transceiver is configured to communicate with the CDMA communication network;
• the display screen is configured to display the first interface and the second interface;
• and
• the audio frequency circuit is configured to output a sound, wherein the sound comprises a call voice between the terminal and a second terminal, a prompt tone, or a prompt tone and a call voice between the terminal and a second terminal,
• the one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one a processor to perform operations comprising:
• displaying a first interface on a display screen, wherein the first interface shows that a first terminal is in a call with a second terminal via a CDMA communication network;
• while the first terminal is in the call with the second terminal, displaying a second interface on the display screen, wherein the second interface prompts that a third terminal is initiating a call to the first terminal via the CDMA communication network;
• instructing the audio frequency circuit to output a sound, wherein the sound comprises a prompt tone and a call voice between the first terminal and the second terminal, the prompt tone is used to prompt a call event, and the call event indicates that the third terminal is initiating a call to the first terminal via the CDMA communication network;
• in response to the call initiated by the third terminal to the first terminal being rejected by a user of the first terminal, instructing the audio frequency circuit to continue outputting the call voice between the first terminal and the second terminal, and to stop outputting the prompt tone to stop prompting the call event.

At least one processor used in a Code Division Multiple Access CDMA communications network in a first terminal, wherein the at least one processor is coupled to one or more memories that store programming instructions and the programming instructions, when executed by the at least one processor, cause the at least one processor to perform the following operations:

• establishing a call with a second terminal via the CDMA communication network;
• receiving a message from the CDMA communication network, wherein the message indicates that a third terminal is initiating a call to the first terminal via the CDMA communication network, and at this moment, the first terminal is still in a call with the second terminal while the first terminal is in the call with the second terminal;
• outputting a sound, wherein the sound comprises a prompt tone and a call voice between the first terminal and the second terminal, the prompt tone is used to prompt a call event, and the call event indicates that the third terminal is initiating a call to the first terminal via the CDMA communication network;
• in response to the call initiated by the third terminal to the first terminal being rejected by a user of the first terminal, continuing output, on the first terminal, of the call voice between the first terminal and the second terminal, and stopping output of the prompt tone to stop prompting the call event.
