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, by the source proxy, a first transport control protocol, TCP, session for the UE with an anchor proxy designated for a content server, transmitting, by the source proxy, to the UE, data received from the content server through the first TCP session; receiving, by the source proxy, 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, by the source proxy 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, wherein a second TCP session is established between the anchor proxy and the target proxy; transmitting, by the source proxy to the target proxy, the session information associated with the first TCP session; and in response to a handover start notification being received from the source base station, stopping, by the source proxy, the first TCP session, and transmitting, to the target proxy, state information comprising a context of a TCP session between the UE and the source proxy and a context of the first TCP session between the source proxy and the anchor proxy; wherein the anchor proxy is configured to bind a context of the first TCP session and a context of a 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, and wherein data received from the content server is transmitted to the UE connected to the target proxy through the second TCP session by the anchor proxy, after a handover complete notification is transmitted to the anchor proxy from the target proxy. receiving, by a source proxy, a connection request from a user equipment, UE, via a source base station; establishing, by the source proxy, a first transport control protocol, TCP, session for the UE with an anchor proxy designated for a content server, transmitting, by the source proxy, to the UE, data received from the content server through the first TCP session; receiving, by the source proxy, 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, by the source proxy 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, wherein a second TCP session is established between the anchor proxy and the target proxy; transmitting, by the source proxy to the target proxy, the session information associated with the first TCP session; and in response to a handover start notification being received from the source base station, stopping, by the source proxy, the first TCP session, and transmitting, to the target proxy, state information comprising a context of a TCP session between the UE and the source proxy and a context of the first TCP session between the source proxy and the anchor proxy; wherein the anchor proxy is configured to bind a context of the first TCP session and a context of a 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, and wherein data received from the content server is transmitted to the UE connected to the target proxy through the second TCP session by the anchor proxy, after a handover complete notification is transmitted to the anchor proxy from the target proxy.
