Stoke, the leading security developer for mobile networks, in a statement said that it is critical to protect and encrypt each partner's traffic in a shared LTE network. As the LTE network sharing is on the rise due to market forces and regulators pushing for greater penetration of broadband, Stoke added that DIAMETER-Based Accounting and Policy Management defuses new risks and enables accurate billing.
In addition to regulators mandate to encrypt mobile virtual operator's traffic using IPsec from the shared Radio Access Networks (RAN) to their core networks, Stoke cautined that wholesalers need mechanisms to implement policy enforcement at the common aggregation point in the event that a partner is in violation of the service level agreement.
According to Stoke, the crucial area and first point of defense is at the edge of the RAN, before the traffic passes through the operator's data center. The Stoke security gateway is situated in this natural aggregation spot in the network and also features the ability to provide latency-free traffic security as well as DIAMETER-based inter-carrier accounting and policy enforcement.
