Patent ID: 8213909

Claim:
A method of providing voice message call service in a service providing apparatus that is connected to a calling terminal, a Mobile Switching Center (MSC)/Personal Communication exchange (PCX) and a called terminal through a mobile communication network, the method comprising the steps of: receiving a call access request signal from the MSC/PCX, wherein the call access request signal corresponds to a first call set-up request signal received from a calling terminal by the MSC/PCX; sending a call access response signal to the MSC/PCX in response to the call access request signal, wherein the MSC/PCX sends a first call set-up response signal to the calling terminal in response to the call access response signal; receiving a voice message, which will be transferred to the called terminal from the calling terminal through a first call path established with calling terminal in accordance with the call access response signal and the first call set-up response signal; terminating the first call path; sending a first outbound call request signal to the MSC/PCX for call connection to the called terminal, wherein the MSC/PCX sends a second call set-up request signal to the called terminal in response to the first outbound call request signal and receives a second call set-up response signal in response to the second call set-up request signal; receiving a first outbound call response signal from the MSC/PCX in response to the second call set-up response signal; sending the voice message to the called terminal through a second call path established with the called terminal in accordance with the second call set-up response signal and the first outbound call response signal; sending a guidance message for reply to the called terminal; receiving a response message, which will be sent to the calling terminal, from the called terminal; terminating the second call path; sending a second outbound call request signal to the MSC/PCX for call connection to the calling terminal, wherein the MSC/PCX sends a third call set-up request signal to the calling terminal in response to the second outbound call request signal, and receives a third call set-up response signal in response to the third call set-up request signal; receiving a second outbound call response signal from the MSC/PCX in response to the third call set-up response signal; and sending the response message to the called terminal through a third call path, which is established with the called terminal, in accordance with the third call set-up response signal and the second outbound call response signal.
