IP Federating Network architecture IPFN

1. IP Federating Network architectureIPFN ETSI Services and Protocols for Advanced Networks-SPAN Overall Network and System Architecture-ONSA Walter.LEGRAND@eads_dsn.com Advanced programs and standards manager PSPP meeting 26/10/00

2. Radio Access Radio Access The issues in crisis situations Data Bases (GIS, evt…) IT Information centers GPS Servers Administrations IPFN Industry site Operators Intranet Fixed network VPN Public safety/ Emergency services CITIZENS Sensors

4. The IP Federating Network (IPFN) • An IP ‘ Virtual Private Network ’, with specific Sub Systems connected to it, interconnecting the Wireless (and fixed) accesses for Voice and Data and offering levels of Services • The IPFN shall allow Voice and Data communication VPNs features to share INFORMATION and garantee Security • The IPFN shall offer new Services to the users • The IPFN shall allow interworking • Different ‘ functionnal ’ sub systems are added • mapped to a scalable hardware configuration • Fully digital, where ‘ Voice is Data ’ • Legacy systems into account

5. Services offered (notion of Levels) • Voice services • Data services (SMS…) • Mobility services (MIP…) • Security services (IPSec, PKI, L2TP,Policy...) • Directory and @dressing services • QoS services • Priority services • Translation services (information format, language…) • Web - Application services • Administration services (SNMP…) • Interoperability services (to SAT, UMTS…) • Localisation services (GIS, GPS…)

6. IPFN Architecture Network A Proxy Redirect Server MCU GW_nwkA IP VPN Registration Server Security Server Management Directory SERVER Radio access Radio access

7. Functional sub systems • Call handling • Security, QoS… • Radio, Line Access…. • The Directory server (LDAP…) • MCU (Media Conferencing Unit) • DNS (@dressing…) • Translation, Application server (IT) • Network Management • Gateways • VoIP interface: MEGACO/MGCP-ETSI/TIPHON - Voice over IP • VPN gateways-Firewalls

8. IP technology enabled • Voice over IP • SIP based • XML based • IP addressing • With QoS, Priority mechanisms • ………... • Control rooms/dispatch are fully integrated as IT systems (SOAP…) • ‘ Light ’terminals • ………... • With Security (IPSec, SIM…)

9. Network Architecture with RadioSubsystems Network A Network B Proxy Redirect Server MCU proxies MCU proxies GW_nwkA GW_nwkB Registration Server Security Server Management HLR EIR* RS RS EIR :Equipement Identity Register. GCR:Group Call Register. GCR* Mobile Station The RS is seen as a set of IP subscribers hiding the Radio specificities of the mobiles

10. Functional units...methodology (UML, SDL…) • The functional services are distributed in functional units: • Call control • Call user agent • Call proxy server • Call gateway • Call media conference function • Data • Data user agent • Data proxy server • Data gateway • Directory • Directory server • Directory client Scalability

11. Functional architecture • User agent • Call proxy redirect server • Data proxy/redirect server • Call Gateway to external network • Data Gateway to external network • Media conference unit • Home mobility server • Visitor mobility server • Security server • Directory server • Operational and Network management

13. Signalling & control WAP Subscriber management Voice over IP Configuration management RTP SIP/SDP HTTP LDAP SNMP UDP MIP TCP IP with IPSec Anything Network protocol stack Air interface independent protocols

14. Network protocol stack RTP Real Time Protocol for voice packet transport SIP/SDP Session Initiation Protocol and Session Description Protocol for call setup and release, call extension, multicast call, tracing and voice logging

15. Network protocol stack IPSec Security association and key management protocol for non air-interface security MIP Mobile IP for packet oriented data transmission WAP Wireless application protocol for small interactive data transmission

16. Network protocol stack LDAP Light Directory Access protocol for secure management of subscribers rights with distributed directory databases SNMP Simple Network Management Protocol interfaces with many standard platforms for network management
