Diameter Edge Appliance™ – Diametriq’s Diameter Edge Agent
IPX Connectivity for LTE Roaming
Larger Mobile Network Operators that have multiple instances of EPC network elements will need a Diameter Routing Agent (DRA) to efficiently route signaling traffic and perform load balancing, relay, proxy and redirect functions. For LTE roaming, a Diameter Edge Agent can be added for connection to an IPX or directly to another Wireless Network Operator.
Many Mobile Network Operators do not have multiple instances of EPC elements and do not require a Diameter Routing Agent. However for LTE roaming, EPC network elements in a Mobile Operator’s network will need to connect to the corresponding network elements in a partner Mobile Operator’s network, through a Hosted DRA/DEA service of an IPX provider, or or a combination of the two. This will require multiple secure IP connections .
If the Mobile Network Operator connects to more than one IPX or if it connect directly to other operators, these connections will have to be duplicated for each one. If the Mobile Network Operator has an on-site Diameter Edge Agent (DEA), only one connection is required for each IPX or direct connection to other operators (local breakout). The DEA also provides topology hiding to protect the network elements and addresses from being exposed to foreign networks.
Diametriq offers an appropriately scaled subset of its Diameter Solution Suite™ which is well suited to this application. The Diameter Edge Appliance™ is a cost-effective yet highly reliable carrier-grade Diameter Edge Agent with unique features that differentiate it from the competition.
