ABSTRACT:
In an embodiment, an existing transport protocol connection though a mobile device is recognized as having entered a state of disconnect. A lowest received sequence number is determined from received messages to be transmitted over a disconnected transport protocol connection. A disconnect acknowledgement message with a receive window of zero and a sequence number of one less than the lowest received sequence number is transmitted. The disconnect acknowledge message with a receive window of zero and a sequence number of one less than the lowest received sequence number is continued to be transmitted until the transport protocol connection exits the disconnect state to a connect state.
