| titleOfInvention | Method and system for broadcast and call based on VoIP |
| abstract | The present invention relates to a VoIP-based broadcasting and calling method. This VoIP-based broadcasting and calling method is the process of installing the first COP and the second COP each having a SIP server function at the front and rear of the train, providing an emergency interphone call function in the train cabin, and a SIP client function. The process of installing at least one PEI having, providing a broadcasting function to the cabin of the train, and installing at least one PAMP having a SIP client function, one of the first and the first COP and at least one PEI A process of performing an emergency interphone call by VoIP communication using the SIP server function and the SIP client function, and VoIP communication using the SIP server function and the SIP client function from one of the first and second COPs to at least one PAMP. It includes the process of providing a large passenger broadcast. According to the present invention, on the basis of VoIP communication using a SIP server and a SIP client function, it is possible to process manual and automatic train passenger broadcasts, emergency interphone calls in cabins, and calls with ground control systems in railway vehicles. |
