Abstract
A method is disclosed for avoiding unnecessary keepalive data transfers, comprising: receiving, at an upstream TCP connection endpoint in a radio access network (RAN) from an operator core network, an Internet Protocol (IP) packet; performing, at the upstream TCP connection endpoint, shallow packet inspection on the IP packet; and forwarding the IP packet to the downstream TCP connection endpoint in the RAN if the IP packet is not a keepalive packet, based on the performed shallow packet inspection. The upstream TCP connection endpoint in the RAN may be one of a nodeB, an eNodeB, a base transceiver station (BTS), a coordinating server, and a mobile edge computing (MEC) gateway. The downstream TCP connection endpoint in the RAN may be one of the nodeB, the eNodeB, or the base transceiver station (BTS).
