A self-healing approach for LTE Evolved Packet Core

The 3GPP Long Term Evolution (LTE) is considered as a dominant future cellular wireless technology in terms of performance and user experience. With technological advancement of wireless networks, dependencies and business impact of mobile network services have also been increased phenomenally. It is, therefore, crucial to address issues regarding network infrastructure or service failure. In this paper, a self-healing solution is presented for LTE Evolved Packet Core (EPC) with a view to maintaining service continuity in the event of network elements failures. Restoration mechanism and associate operational procedures with regards to service survivability are described in details. Simulation results are provided and the results demonstrate potential of this approach.
