Advanced Connection Manager for Interworking between 3GPP and Non-3GPP Networks

Abstract

Smart phones and handheld devices equip with multiple radio access technologies capabilities e.g. cellular and Wi-Fi now a days. It is observed that seamless session and service continuity is a difficult task while device is roaming across different radio access technologies. Connection Manager, ANDSF and Traffic Steering Algorithms are mainly used to address such switching requirements. Radio access selection decision is usually based upon various parameters like network capabilities, availability, quality, subscription and policies. This research compares network quality of all available networks for the duration and then connection manager’s decision support system ranks all suitable networks to select most appropriate access network. This paper investigates about new input parameters to be included in connection manager’s enhanced decision support system for the smarter decision of access network selection.
