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.
