Step S120, the called number in the privacy communication call request is analyzed based on the privacy communication call message, and the attribution information of the called number is obtained through the number attribution inquiry unit.
Specifically, the privacy communication platform analyzes the called number in the privacy communication call request based on the received privacy communication call message, and rapidly acquires the attribution information of the called number through the national number attribution inquiry system.
Step S130, the routing path of the private communication call is calculated according to the routing decision parameter table to generate a routing instruction, and the routing instruction is sent to the I-SBC address of the originating call or the target I-SBC address of the called number to establish the communication session between the originating call user terminal and the called number user terminal.
Specifically, the privacy communication platform calculates an optimal route path of the privacy communication call according to a preset route decision parameter table to generate a corresponding route instruction, and sends the route instruction to an I-SBC address of the calling or a target I-SBC address of the called number, and after receiving the route instruction, the I-SBC address or the target I-SBC address of the calling establishes a communication session between the calling user terminal and the called number user terminal according to the calculated optimal route path in response to the route instruction.
