Intelligent Network Intelligent Network Wireless Wireless PSTN TINA-C style architectures are emerging in many places in the next generation network “Open” “Closed” Internet “Open” User Services Service Provider Services Service Control “Closed” PSTN Internet Network Dependent Services Hosted Services on Open Networks
Softswitch follows a TINA-C style architecture • There is a disaggregation of services, switching, transport, and access • Services interwork across multiple network types • Open and flexible interfaces - API’s & protocols, allow ISVs to create new services • Standard API’s Softswitch Model Billing System Management System New Services Signaling control control IP ATM IP ATM PSTN PSTN Packet Data Backbone Media Gateway Media Gateway
Internet PSTN 3G-wireless networks are following the TINA-C style architecture Softswitch-based Soft Mobile Switching Center Media Gateways Radio Network Control Common Base Stations
Service optical networks are following TINA-C style architectures - though with very different API’s and “call models” • New Style Optical Services • Bandwidth Trading • Optical VPN’s • Selectable QoS • Customer Programmability
Open network case study - what happened with AIN services? SCP ONLY SCP + Adjunct Advanced Toll-Free Automatic Callback Area Number Calling IN Unified Messaging Authentication Center Network Announcements E911 Incoming Call Screenin Internet Call Diversion Short Message Service Center LIDB services Voice Activated Dialing Local Toll Free (800 portability) Personal/Single Number Servic Network ACD/Contact Center E-mail reader Number Portability Instant Messaging (e.g. "Teen talk") Over-the-Air Service ProvisioningInternet Call Waiting/Management PrePaid Service Personal Assistants Standalone Home Location Register Talking Call Waiting TelevotingOutgoing Call Screening/ Calling Party Pays Calling Party Verification Location Based Services Flexible Alerting/simultaneous ringing Virtual Private Network Calling Card Calling Name display Vendor ISV, Telco, & Vendor
There was not an explosion in network services with AIN - Why Not? • Limited Functionality End User Device? • Operations & Tariffing Complexities? • Disparate, Partially Deployed Switch Triggers? • Voice Services Running Dry? • Feature Interaction?
Feature interaction is a complex network services attribute that can prohibit an open programming environment for network services • When the subscriber is busy, an incoming call triggers a cw tone at the subscriber and a normal dial tone at the caller. The cw tone can be repeated at most once. After a 10 sec interval (9..30sec)…… (Telcordia LSSGR) • Feature interaction occurs when a feature’s behavior changes - intentionally or unintentionally - in the presence of another feature • Circular Call Forwarding • Unlisted Number, Caller ID, E911 & “Hang up” • Call gapping & emergency calls • Internet Call Waiting & Call Forwarding On No Answer • Denial of service, distributed attack? • Emergency virus shield download?

Several major challenges remain To achieve TINA-C objectives • Feature Interaction (and the degree of access to core network) • Next Generation Networks “Stitching” Integration • PINT • SIP • Widely-Supported Standard “Service” API’s For Application Domains • Progress with JAIN, Parlay, OSA • Business integration with the WEB world is needed • Open Telecommunications & Information Software Component Marketplace in Network Management • Group of Seven • ITU
