1. A method, comprising:
- concentrating a plurality of signaling messages from at least two radio access network nodes to a core network node at a signaling concentrator located between the at least two radio access network nodes and the core network node;
processing the plurality of signaling messages with a mobile device identifier rule at the signaling concentrator, at approximately a line rate of at least one link from the at least two radio access network nodes to the signaling concentrator;
adding together backhaul line rates of each of the at least two radio access network nodes coupled to the signaling concentrator to compute the line rate; and
providing compute resources sufficient to handle signaling messages received at or approaching the line rate,wherein the mobile device identifier rule further comprises an association of an identifier of a source mobile device for each of the plurality of signaling messages with a message processing rule, the message processing rule further comprising instructions for determining whether to drop each of the plurality of signaling messages,thereby providing core network offload of the core network node by the signaling concentrator.
