Sommario

La banda dei sistemi mobili è destinata a crescere significativamente

Crescita dei servizi Internet multimediali basati su sistemi mobili

– Introduzione del sistema IP Multimedia (IMS)– Convergenza delle reti, dei servizi…– … e dei terminali: terminali mobili sempre più simili a

terminali Internet

La sicurezza nei futuri sistemi mobili e nelle reti di convergenza è un aspetto cruciale

What is IMS?

• IP Multimedia Subsystem (IMS) is an architecture for offering services on the packet domain.

• Not just Voice over IP - IMS is a generic architecture for offering multimedia services

• IMS is access agnostic, hence it is not just for UMTS or GPRS, but will also support WLAN, fixed line, etc.

Relation with other services

IMS is not related to other services (e.g., streaming, messaging, presence, etc.)

– Because IMS is not a service– But IMS is a service enabler– So all the services (e.g., streaming, multimedia messaging,

presence) can be delivered by using IMS


Slide title 40 pt

• Person-to-person communications aided by the always on model

• Person-to-machine communications• Machine-to-machine communications (e.g. telemetry)• Convergence of all media communications on to the

packet network• Multimedia communications based on a single solution

What does IMS give? 1/2

What does IMS give? 2/2

• Significant reduction in the cost of networks both in terms of capex and opex by supporting both native IP based services and voice services on IP

• Service control by introducing service signalling• Access agnostic• Integrated charging architecture• Personalised services are shorter lived or need to be

tailored for smaller groups of individuals. Rapid service creation is vital

La convergenza

La convergenza aumenta considerevolmente le opportunità di servizi per i clienti e la possibilità per gli operatori di abbattere i costi e fidelizzare i clienti.

D’altra parte questo complica gli aspetti di sicurezza: es. reti multiaccesso IMS nato per il mondo UMTS, sarà la pietra angolare per le future reti di convergenza

Le reti mobili sono strettamente controllate dagli operatori

Gli SMS sono a pagamento

I terminali hanno funzionalità limitate

I terminali hanno sistemi operativi chiusi che non

permettono il download e l’esecuzione di applicazioni

esterne (viruses)

I telefoni mobili 2G non sono un facile target


Slide title 40 pt


Text 24 pt



Aumentano le interazioni con il mondo Internet (molto

meno controllato rispetto alle reti mobili)

I terminali GPRS e 3G hanno funzionalità molto più

sviluppate rispetto ai telefonini 2G

I nuovi terminali hanno sistemi operativi aperti (Symbian

or Windows Mobile)

I terminali possono ricevere e_mail da Internet in modo

economico o gratuito

L’avvento del 3G e dei servizi multimediali apre le porte a nuove minacce

Will they damage my phone ? Will they damage my friendships ? Will they steal money from me ?

La sicurezza è un problema fondamentale per i sistemi mobili di nuova generazione

L’Internet mobile apre nuove frontiere, ma è necessario rendere sicure le reti

La convergenza aumenta considereveolmente le opportunità ma complica gli aspetti di sicurezza.

La sicurezza nelle reti mobili di prossime generazioni è un aspetto fondamentale per il successo delle TLC

La ricerca Ericsson in Italia è impegnata nel trovare soluzioni sicure per le reti di prossima generazione multi-accesso
