1. A method of operating a mobility management entity (MME) to manage communication paths, the method comprising:
transferring a plurality of general packet radio service tunneling protocol (GTP) messages to a plurality of packet data network
identifying one or more response messages from the plurality of packet data network gateways;
determining transaction success information for each packet data network gateway in the plurality of packet data network gateways
based on the one or more response messages, wherein the transaction success information comprises a transaction success rate;
identifying when a first transaction success rate for a first packet data network gateway meets transaction criteria; and
when the first transaction success rate meets the transaction criteria, altering communication path allocation to the first
packet data network gateway based on the transaction success information.
