m-VoIP m-VoIP MOBILE VOICE OVER INTERNET PROTOCOL SYSTEM METHOD AND APPARATUS FOR CALL PROCESSING OF MOBILE VOICE OVER INTERNET PROTOCOL IN THE SYSTEM

摘要

The present invention relates to an m-VoIP system and an apparatus and method for m-VoIP call processing in the system. When the calling terminal apparatus makes a registration request through a wireless network, the call processing controller authenticates according to the registration request. And performing registration, when receiving a call origination message from the calling terminal device, performing a push for registration request to the called terminal device, and receiving a push response from the called terminal device, performing a registration procedure of the called terminal device. Then, the call originating message received from the calling terminal device is transmitted to the called terminal device, the response message is transmitted to the calling terminal device, the call related information is exchanged, the call is connected and the call is performed, and the calling terminal device is wireless. If a call termination request is made through the network, the call processing control device may include By terminating the call connection between the calling terminal device and the called terminal device by using the data transmission, the mobile network can be connected only when data transmission is required, and the wireless channel connection can be canceled when data transmission is not required, thereby reducing power consumption. have.
