Abstract
A method in a network node for improving transmission control protocol, TCP, performance in a cellular network is provided. The network node handles TCP packet transferral between a user equipment and a server in the cellular network. The user equipment and the server are configured to adapt a retransmission timeout setting based on round trip times for performed TCP packet transferrals. When the network node obtains an indication of a handover outage being upcoming for the user equipment, the network node deliberately delays, in a time period preceding the indicated handover outage, a transferal of a TCP packet between the server and the user equipment to increase the round trip time for the TCP packet.
