The call preemption method of claim 1, wherein the call parameter information comprises: the Internet protocol address and port information corresponding to the first terminal, and the Internet protocol address and port information corresponding to the second terminal; terminating the call between the first terminal and the second terminal according to the call information parameter comprises:

according to the Internet protocol address and the port information corresponding to the first terminal, a hang-up instruction is sent to a communication port corresponding to the first terminal, wherein the hang-up instruction is used for terminating the ongoing call of the terminal equipment;

and sending the on-hook instruction to a communication port corresponding to the second terminal according to the Internet protocol address and the port information corresponding to the second terminal.

4. A call preemption method as in claim 3, wherein resending call signaling of the third terminal to the first terminal comprises:

and retransmitting the call signaling of the third terminal to the first terminal at a target moment, wherein the target moment is the moment when the on-hook instruction is transmitted to the communication port corresponding to the first terminal.

5. The call preemption method of claim 4, wherein retransmitting call signaling of the third terminal to the first terminal further comprises:

and sending prompt information to the first terminal at the target moment, wherein the prompt information is used for indicating that the conversation currently being called comes from a supervisor.

6. A call preemption method as in claim 3, further comprising:

determining geographic position information corresponding to the second terminal according to the Internet protocol address and the port information corresponding to the second terminal, wherein the geographic position information is used for representing the position of the second terminal;

and sending the geographic position information to the third terminal.

7. The call preemption method of claim 1, wherein forwarding call signaling of a third terminal to a first terminal in the event that the first terminal and a second terminal have established a call further comprises:

acquiring the equipment identifier of the third terminal;

detecting whether the equipment identifier of the third terminal exists in a preset white list database or not, wherein the preset white list database is used for storing the equipment information of the supervision terminal which is registered in advance;

and under the condition that the equipment identifier of the third terminal does not exist in the preset white list database, sending a call signaling of the third terminal to the first terminal, and sending a busy response message returned by the first terminal to the third terminal, wherein the busy response message is used for representing that the terminal planning the call is currently in communication.

8. A call preemption system comprising: an application server, a target network element, a first terminal, a second terminal and a third terminal, wherein,

the third terminal is configured to send a call signaling to the first terminal through the application server;

the application server is used for forwarding call signaling of a third terminal to the first terminal under the condition that the first terminal and the second terminal have established a call, wherein the call signaling is used for intervening in the call process of the first terminal and the second terminal; receiving call parameter information corresponding to the first terminal from a network element of a core network; terminating the call between the first terminal and the second terminal according to the call parameter information, and sending the call signaling of the third terminal to the first terminal again;

the target network element is a network element directly connected with the first terminal in the communication network, and is used for responding to a parameter query instruction sent by the application server and returning the call parameter information corresponding to the first terminal to the application server.

9. A call preemption device, comprising:

a call forwarding module, configured to forward a call signaling of a third terminal to a first terminal when the first terminal and a second terminal have established a call, where the call signaling is used to interfere a call process of the first terminal and the second terminal;

the parameter determining module is used for receiving call parameter information corresponding to the first terminal from a network element of a core network;

and the call preemption module is used for terminating the call between the first terminal and the second terminal according to the call parameter information and sending the call signaling of the third terminal to the first terminal again.

10. An electronic device comprising a processor, wherein the processor is configured to run a program, wherein the program is configured to perform the call preemption method of any of claims 1-7 when run.

11. A non-volatile storage medium, characterized in that the non-volatile storage medium comprises a stored computer program, wherein a device in which the non-volatile storage medium is located performs the call preemption method according to any of claims 1 to 7 by running the computer program.
