UMTS (Universal Mobile Telecommunications System) is a 3G mobile communication system that offers high quality wireless multimedia services. It delivers information directly to users and provides access to new services and applications regardless of location, network, or terminal used. The UMTS architecture separates the core network from the radio access network. A UMTS mobile station can operate in PS/CS mode for simultaneous services, PS-only mode, or CS-only mode. UMTS has gone through several releases to support features like HSDPA and all-IP networking.

2. MOBILE SYSTEM GENERATIONS
1 GENERATION(1 G) :Mobile system were designed to offer a
single service, i.e., speech.
2 GENERATION(2 G) :Mobile systems were also designed to offer
limited capability to download data along
with speech.

3. 3 GENERATION(3 G) :Mobile systems are expected to
offer high quality multimedia
services and
4 GENERATION(4 G) :The demand of the speed increases. The
technologies included are Wi-Max and
LTE.

4. UMTS(Universal Mobile
Telecommunications system)
UMTS will be a mobile communication system that
can offer significant user benefits including high
quality wireless multimedia services.
It will deliver information directly to users and
provide them with access to new and innovative
services and application.
It’ll offer mobile personalized communication to the
mass market regardless of location , network and
terminal used.

5. UMTS Main
Requirements
 MULTI-MEDIA.
MULTI-ENVIRONMENT.
MULTI-OPERATOR(VIRTUAL
OPERATOR).

9. UMTS mobile station can operate in one of three modes of
operation: PS/CS mode of operation: The MS is attached to both the PS
domain and CS domain, and the MS is capable of simultaneously
operating PS services and CS services.
 PS mode of operation: The MS is attached to the PS domain
only and may only operate services of the PS domain. However,
this does not prevent CS-like services to be offered over the PS
domain (like VoIP).
 CS mode of operation: The MS is attached to the CS
domain only and may only operate services of the CS
domain.
