SYSTEM AND METHOD FOR PROVIDING DUAL MODE DATA ACCESS SERVICE TO USER EQUIPMENT USING WI- FI OFFLOADING OF LTE SPECTRUM

摘要

ABSTRACT Disclosed herein is a system and method for providing dual mode data access to a Wi-Fi enabled User Equipment (UE) by using Local IP Access (LIPA) based extended S1 mode of operation in an LTE network. The system facilitates traffic flow based offloading of data services from LTE network to a Wi-Fi network. The UE with dual mode data access capability can be configured to avail the dual mode data access service. When the UE requests for a data service to the network, with dual mode capability, the UE is allowed to connect through other access network like Wi-Fi and put on new mode of access at core network called extended S1 mode of operation, after performing necessary authentication. In this new mode of operation i.e. Extended S1 mode of operation the data services to UE may be provided using LTE, Wi-Fi, or both. Fig. 1
