Our combined in-depth expertise on Telecom and Connectivity helps customers build future-ready solutions at an accelerated pace.Customers can leverage GlobalEdge expertise in developing, sustenance and testing of LTE Wi-Fi offload framework solutions.


LTE Wi-Fi Offload framework feature summary:

  • ANDSF framework
    • Discovering of non-3GPP Access Networks
    • Dynamic updates of framework parameters and functions using OMA DM protocol
  • Policy controller
    • Inter System Routing Policies (ISRP) – Allows to access multiple radio access technologies simultaneously
    • Inter System Mobility Policies (ISMP) – Allows to access a single radio access technology
  • Seamless handover mechanism
    • Secured access on S2c interface, both for trusted and unmanaged or un-trusted hotspots
    • DSMIPv6 – Ensures a smooth handover that works in a make-before-break manner over S2c interface
    • EAP-AKA/SIM Authentication
  • IFOM -IP Flow Mobility is a mechanism to provide seamless Offload of a data traffic.
  • OMA DM client
    • Provisioning – Configuration of the device (including first time use), enabling and disabling features
    • Device Configuration – Allow changes to settings and parameters of the device
  • Connection manager

Connection manager provides notifications to the LTE Wi-Fi Offload framework for triggering data offload functionality upon the detection of a RAT from Wi-Fi to 3GPP packet core network and vice versa
