Abstract: Disclosed herein is a method and network handover system for handling a data session in a user equipment (UE). The method comprises initiating a data session of at least one application from a plurality of applications with a first communication interface using a first socket of the UE having a first socket file descriptor (SOCKFD) for the data session, detecting a deterioration in a network connection of the first communication interface, identifying a second communication interface, establishing a second socket having a second SOCKFD associated with the second communication interface and migrating the data session from the first communication interface to the second communication interface by mapping the first SOCKFD corresponding to the first socket to the second SOCKFD corresponding to the second socket.

Abstract: Embodiments herein include a method for concurrently performing asynchronous operations over IPv4 and IPv6 in a mobile device. The method includes capturing a DNS query-pattern of a plurality of DNS queries for a plurality of services of an application in the mobile device. Further, the method includes performing a DNS lookup in a DNS cache, to obtain a DNS resolution over the IPv4 and the IPv6 based on the DNS query-pattern of the plurality of DNS queries for the plurality of services of the application. Further, the method includes storing the DNS resolution based on the DNS lookup in the DNS cache. Further, the method includes triggering a TCP connection using a pre-connected connection descriptor based on a domain name resolution. Further, the method includes storing the pre-connected connection descriptor corresponding to the TCP connection in a connection pool cache.

Abstract: The embodiments herein disclose methods and systems for reducing network protocol latency for at least one application on an electronic device, a method includes pre-resolving a plurality of Domain Name System (DNS) queries for the at least one application. The plurality of DNS queries is pre-resolved before triggering at least one DNS resolution query from the at least one application. The method includes pre-connecting a plurality of TCP connections of the at least one application with at least one Transmission Control Protocol (TCP) server. The plurality of TCP connections are pre-connected before triggering at least one TCP connection request from the at least one application. The method includes exchanging a plurality of secure certificates with the at least one TCP server to secure the plurality of pre-connected TCP connections. The secure certificates are exchanged before receiving at least one request from the at least one application for secure certificate negotiation.

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.
