Abstract: The present disclosure relates to an apparatus and a method for controlling Transmission Control Protocol (TCP) connection close to improve a battery life time of a client such as a smart phone in a wireless communication system are provided. A method of operating a client in a wireless communication system includes determining a data transfer inactivity time of at least one of TCP connections, and closing the at least one of TCP connections at the data transfer inactivity time.

Abstract: Embodiments herein provide a TCP optimizer (TO) and method for controlling TCP packets due to closure of a TCP connection for power saving. The method includes monitoring TCP closures, for controlling the TCP packets. The TO can be configured to determine a pattern of TCP packets based on a plurality of parameters associated with a TCP connection. Further, the TO can be configured to detect that the pattern corresponds to a TCP closure retransmission or TCP zero window closure category based on a historic pattern of TCP packets. Further, the TO can be configured to terminate the TCP connection. The proposed method allows controlling TCP packets to save power in a mobile device thus improving the life time of a battery of the mobile device.
