Abstract:
1. A method, comprising: receiving from a mobile station at a performance enhancing proxy via a base station of a cellular network a split transport control protocol connection request to connect to an end point destination, the split transport control protocol connection request comprising information for identifying a first internet protocol address (x1) of the mobile station and a fourth internet protocol address (x4) of the end point destination, where a network node in the cellular network comprises the performance enhancing proxy; in response to receiving at the network node of the cellular network the split transport control protocol connection request from the mobile station, selecting a second internet protocol address (x2) and a third internet protocol address (x3) to be used on the performance enhancing proxy for the split transport control protocol connection request; and establishing a split transport control protocol connection comprised of a wireless transport control protocol connection between the mobile station using the first internet protocol address (x1) on the mobile station and the performance enhancing proxy using the second internet protocol address (x2) on the performance enhancing proxy, and a transport control protocol connection at least part way between the performance enhancing proxy and the end point destination using the third internet protocol address (x3) on the performance enhancing proxy, where establishing the split transport control protocol connection includes sending the second internet protocol address (x2) to the mobile station to be used for the split transport control protocol connection.
