openepc_components_horizontalhandoversOpenEPC supports many of the possible horizontal hand-overs. Mobility is provided not only for simple 2G, 3G and LTE connectivity, but also handing over between cells of the same or different technologies is possible. Even re-selection of MME/SGSN is possible, with SGW reselection under development and available on demand.

The following table seeks to highlight the current capabilities. If one capability critical for you would be missing, do not hesitate to get in contact with us for the latest state or an eventual evaluation for providing it as an on-demand feature.
