Real-time SS7 and SIGTRAN signalling routing for 2G to 3G networks, handling both PCM SS7 on COTS hardware and IP signalling on cloud.
Every network element generates signalling. The MSC, HLR, SMSC, and the rest all need to exchange SS7 messages to set up calls, deliver SMS, and look up subscribers. Without a routing hub, each element has to address every other element directly, and every interconnect with another operator adds another set of direct links to maintain.
Operators also run two kinds of signalling at once. Legacy network elements speak PCM SS7. Newer elements speak SIGTRAN : SS7 over IP. A network that cannot route both on one platform ends up maintaining two signalling layers, each with its own configuration and failure points.
The mesh grows without an STP
The STP is the signalling routing hub of the network. Every SS7 message from an MSC, HLR, SMSC, or external operator arrives at the STP, which routes it to its destination based on Point Code, Global Title, and other addressing criteria. Elements no longer need to address each other directly. They address the STP. The star topology reduces the number of links and reduce latency.
Connect once to the STP pair
The Ouroboros STP handles both legacy PCM SS7 links, Low Speed Links and High Speed Links, and SIGTRAN M3UA (SS7 over IP).
Global Title routes the query
It deploys on COTS hardware. No proprietary signalling chassis is required.
STP — quad-node redundant signalling mesh
Hub-and-spoke signalling, SS7-SIGTRAN bridging, roaming routing, GT translation, SS7 screening — one platform.
Consolidating legacy and IP signalling
An operator running both PCM SS7 and SIGTRAN routes both through one STP. The legacy and IP signalling layers share a single routing configuration instead of two separate platforms.
Inter-operator interconnect
Signalling to and from external operators is routed and screened at the STP. Rules determine which links should be used per destination, commercial contract...
Internal signalling routing
SS7 between the MSC, HLR, SMSC, and other elements is relayed through the STP by Point Code and Global Title. Adding or moving an element updates the STP routing table rather than every element it talks to.
PCM SS7 and SIGTRAN on one platform
The STP routes legacy PCM SS7 links (LSL and HSL) and SS7 over IP through the same platform. Legacy and IP signalling run through one routing hub. No second platform for the IP signalling layer.
Point Code and Global Title routing
Messages route to Signalling End Points by Point Code, Global Title, and other addressing criteria. Network elements address the STP, not each other. Adding an element is a routing-table change.
COTS hardware deployment
The STP runs on standard commercial hardware. No proprietary signalling chassis to procure or maintain.
The STP covers 2G to 3G signalling on one platform, routing both legacy PCM SS7 and SIGTRAN. It runs on COTS hardware as part of a platform in production since 2004 across 30+ countries.
