Abstract
The disclosure includes a method for rapidly recovering the speed of TCP transmission after a cross technology handover experienced by a mobile device. In the method, the mobile device receives a sequentially first TCP data packet after the cross technology handover completes via a TCP session between the mobile device and a remote TCP server, generates a first acknowledgement (ACK) associated with the sequentially first TCP data packet, where the first ACK comprises a first Selective ACK (SACK) option, removes the first SACK option from the first ACK when a gap exists between data in the sequentially first TCP data packet and data received before the cross technology handover occurs, and sends the first ACK without the first SACK option to the remote TCP server via the TCP session. Because the ACK is without the SACK option when the gap exists, the speed of TCP transmission will be recovered rapidly.
