Whats signaling used for?
? Transfer of control- and status information between telecom nodes (switches), terminals (phones) and users.
? Control information consists of:– Connect/Disconnect of phone calls– Handling of mobility (in mobile networks)– Charging/Billing– Handling of intelligent network-based services– Service like ”A-number presentation” and ”call completion”
? Status information is used for:– Rerouting of signaling– Ensure highest possible security, availability and performance

Signaling System No.7 (SS7)
? “Nervous system” of fixed & mobile telecom networks
? International standard since 1980 (ITU)
? Separate signaling from data/speech connections
? Provides fast call establishment
? High throughput, reliability and capacity
? Provides flexibility in network design
? Prevents from fraud
? Enable new services (e.g. IN and GSM/UMTS)
![Page 16: Welcome to Karlstad and TietoEnator](https://reader031.vdocuments.net/reader031/viewer/2022012015/615a16fc9387c91477114f6e/html5/thumbnails/16.jpg)

SS7 Technology
? Built according to a standardized layered model
? Layers are combined to provide wanted service
? Each layer hosts a so called Protocol
? Basically three different standards:– ITU (Europe, Asia)– ANSI (North America)– TTC (Japan)

Today´s trends
? Unbundling Services from Networks
? Seamless services increasingly important
? IP-based Transport/Connectivity layer
? Service support for multi-media
? Allow for third-party service provisioning
? Open service creation & execution environment based on high-level APIs towards the network
![Page 25: Welcome to Karlstad and TietoEnator](https://reader031.vdocuments.net/reader031/viewer/2022012015/615a16fc9387c91477114f6e/html5/thumbnails/25.jpg)

Signaling evolution
? Separation of signaling and connectivity/transport
? Signaling carried over different transport types:– STM– ATM– IP
? Same or better QoS as today's SS7 signaling
? New protocols to support multimedia– SIP/SDP
? Convergence solutions needed (i.e. gateways)
? High level APIs required for services– JAIN– Parlay
