It is to be understood that the terminology used in the embodiments of the present invention is for the purpose of describing the particular embodiments, and is not intended to limit the invention. The singular forms "a", "the" and "the" It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

Referring to FIG. 1 , FIG. 1 is a flowchart of an embodiment of a call control method according to the present invention. The method is applied to a system including a first terminal, a second terminal, and a third terminal, where the first terminal, The second terminal and the third terminal, both of which can be smart phones, both support the VoLTE audio call function and activate the VoLTE service, and the method includes:

Step S101: The second terminal establishes a call connection with the third terminal by using a VoLTE function.

Specifically, the second terminal establishes a call connection with the third terminal by calling the third terminal or answering the call of the third terminal.

Step S102: The first terminal establishes a call connection with the second terminal by using a VoLTE function.

When the second terminal is in the call state, other terminals, such as the first terminal, may call the second terminal; the second terminal answers the call of the first terminal, and establishes a call connection with the first terminal. Alternatively, the second terminal needs to talk with the first terminal at this time, and initiates a call to the first terminal; the first terminal answers the call of the second terminal, and establishes a call connection with the second terminal.

It should be noted that step S101 and step S102 may be performed in sequence, that is, the first terminal establishes a call connection with the third terminal before the second terminal establishes the call connection, that is, when the first terminal and the second terminal are in a call state. At this time, the first terminal makes a call to the second terminal or answers the call of the second terminal; step S101 and step S102 can also be performed simultaneously, for example, the second terminal simultaneously calls the first terminal and the third terminal, and the first terminal The terminal and the third terminal respectively establish a call connection, or simultaneously answer the call of the first terminal and the call of the third terminal.

Step S103: The first terminal sends the collected first audio information to the second terminal.

Specifically, the first audio information may include voice information and/or video information collected by the first terminal, where The first terminal collects voice and voice information through a sound sensor, such as a microphone, and collects video information through the camera. The first terminal sends the first audio information to the base station, and the first audio information is sent by the base station to the second terminal.

Optionally, the first terminal may further send the first audio information forwarding right to the second terminal, where the first audio information forwarding right is used to indicate whether the second terminal forwards the first audio information to the third terminal as a relay node. When the first audio information forwarding permission does not allow the second terminal to forward to the third terminal, the second terminal does not satisfy the first forwarding condition, and does not perform step S107, thereby protecting the security of the first audio information.

Step S104: The third terminal sends the collected third audio information to the second terminal.

Specifically, the third audio information may include voice information and/or video information collected by the third terminal, and the third terminal collects voice voice information through a sound sensor, such as a microphone, and collects video information through the camera. The third terminal sends the third audio information to the base station, and the third audio information is sent by the base station to the second terminal.

Optionally, the third terminal may further send, to the second terminal, a third audio information forwarding right, where the third audio information forwarding right is used to indicate whether the second terminal forwards the third audio information to the first terminal as a relay node. When the third audio information forwarding permission does not allow the second terminal to forward to the first terminal, the second terminal does not satisfy the second forwarding condition, and does not perform step S108, thereby protecting the security of the third audio information.
