SYSTEM AND METHOD FOR PROVIDING CONTINUING COMMUNICATION SERVICE ON HOME NETWORK |
摘要 |
A system for providing the continuity of a communication service on a home network and a method therefor are provided to enable an SIP(Session Initiation Protocol) home server to register VoIP/video call terminals inside home as the same group and transmit a call request signal to all VoIP/video call terminals registered as the same group when a call connection is requested from the outside, thereby enabling a user to receive the communication service through a VoIP/video call terminal positioned closely wherever the user is inside the home. A method for providing the continuity of a communication service on a home network comprises the following steps of: registering VoIP(Voice over Internet Protocol)/video call terminals inside home in the same group(S105); transmitting a call request message to the VoIP/video call terminals inside the home of the same group if a call request message is received from the outside(S120); communicating with a first VoIP/video call terminal which transmits a call connection response message if the call connection response message is received from one of the VoIP/video call terminals inside the home in response to the call request message(S150); receiving the location information of a first user which communicates with the first VoIP/video terminal while the call is connected to the first VoIP/video terminal(S260); waiting for the reception of the location information of the first user when a user location verification unavailable message instead of the first user location information is received; and switching the call connection through a second VoIP/video terminal installed at a location corresponding to second user location information if the second user location information different from the first user location information is received in the standby status.
