| 摘要 |
The present invention relates to a method to control a voice call service based on a packet, which enables a voice call service to be stably operated through a circuit network when an overload occurs on a specific base station in a packet network by transmitting voice calls to the circuit network based on each base station in the packet network; and a recording medium and an apparatus for the method. If a session control apparatus, which performs session control for the voice call service based on the packet, transmits to at least one base station apparatus, a redirection request message including an identification information of an overloaded base station apparatus which is a target for overload management, a base station apparatus corresponding to the identification information included in the redirection request message among at least one base station apparatus transmits a redirection message to command a terminal to transmit to the circuit network when receiving a packet-based voice call request message from the terminal. |
