Claim of US Patent No. 9,473,385

1. A method of operating a Long Term Evolution (LTE) network having a plurality of base stations and Service Gateways (S-GWs),
the method comprising:
processing General Packet Radio Service (GPRS) Tunneling Protocol (GTP) packets to determine an amount of GTP tunnels between
the base stations and the S-GWs;

processing the amount of GTP tunnels between the base stations and the S-GWs to determine a target amount of LTE Packet Data
Network Gateways (P-GWs) to serve the base stations;

if the target amount of LTE P-GWs is greater than a current amount of LTE P-GWs, then implementing an additional amount of
virtual LTE P-GWs to serve the base stations; and

if the target amount of LTE P-GWs is less than the current amount of LTE P-GWs, then removing an extra amount of virtual LTE
P-GWs that serve the base stations.
