Claim:
1. A method of supporting a handover through the Internet, the method comprising: receiving, by a source proxy, a connection request from a user equipment (UE) via a source base station; establishing a first transport control protocol (TCP) session with an anchor proxy designated for a content server, and transmitting, to the UE, data received from the content server through the first TCP session; receiving a handover preparation notification including an IP address of the UE from the source base station while the UE is handed over to a target base station; transmitting, to the anchor proxy, session information associated with the first TCP session and information associated with a target proxy related with the target base station; transmitting, to the target proxy, the session information associated with the first TCP session; in response to a handover start notification being received from the source base station, stopping the first TCP session, and transmitting, to the target proxy, state information associated with data transmitted through the first TCP session, wherein data received from the content server is transmitted to the UE connected to the target proxy through a second TCP session by the anchor proxy, after a handover complete notification is transmitted to the anchor proxy from the target proxy, and wherein the anchor proxy is configured to bind a context of the first TCP session and a context of the second TCP session between the anchor proxy and the target proxy, and update the context of the first TCP session as the context of the second TCP session varies.
