Signaling Controller

The Signaling Controller is part of Ericsson’s dual-mode 5G Cloud Core offering, delivering cloud native applications that support EPC and 5G Core 3GPP architectures.

The HTTP signaling is driven by the introduction of the 5G core. The Ericsson Signaling Controller provides a complete cloud native solution for all Diameter and HTTP signaling needs and amongst other things contains world's first Service Communication Proxy (see below). The performance is estimated to be 6 nines (99,9999%). 

The Signaling Controller can be used as:

Service Communication Proxy - Taking care of the HTTP protocol harmonization, overload handling, topology simplification and providing a centralized signaling monitoring tool. This function is included in the initial release and belongs to the Service Proxy Function base package.

Binding Support Function - correlating the data from the packet session and the application service and directs the application function to the right Policy Control Function (PCF). Typical application services are VoLTE and IoT. This function belongs to the Binding Function base package.

Security Edge Protection Proxy - Enabling the 5G roaming and providing security for connections between operators' networks. This function belongs to the Roaming Function base package.

Diameter Agent – routing of signaling messages between nodes in a network, i.e. an aggregation and policing point reducing costs and providing an end-to-end view. This function belongs to the Service Proxy Function base package.

Diameter Edge Agent – routing of signaling messages between operators' networks and providing Diameter firewall and security functions, as well as improving network security by collecting and presenting security related information from roaming interfaces. This function belongs to the Roaming Function base package.

Diameter Routing Agent – routing of signaling messages for policy control and charging, i.e. ensuring that the load is evenly distributed and that messages pertaining to a specific session are routed to the same server node. This function belongs to the Binding Function base package.

Unified Signaling Firewall - Protecting the network from malicious diameter signals. The solution supports SS7, Diameter and HTTP.
