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)
TietoEnator presentation
TietoEnator TietoEnator©2002
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)

TietoEnator in Karlstad
? Develops software for signaling– Full assortment of protocols for all international standards– Unique platform independent architecture– Component-based– “Re-usable” software
? Develops hardware for signaling– Unique “In Service Reconfigurable” architecture– Very high capacity/density
? Our signaling is used in most Ericsson products– 3G products are depending on our SW & HW

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
TietoEnator presentation
TietoEnator TietoEnator©2002
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
