This document discusses information technology in telecommunications. It describes how IT has enabled the operation of telecommunication networks through network management systems that can detect failures in remote devices and manage faults from a control room. It also discusses implementations of key telecommunication technologies like UMTS/3G and the role of IT in supporting the Indian telecom software industry. Major Indian software companies like Wipro, Tech Mahindra and TCS are growing due to increased demand for software services in the telecom sector to support mobile data growth and new technologies.

9. UMTS
UMTS (Universal Mobile Telecommunications Service) is a third-generation
(3G) broadband, packet-based transmission of text, digitized voice, video, and
multimedia data.
UMTS is based on the Global System for Mobile (GSM) communication standard
Once UMTS is fully available, computer and phone users can be constantly
attached to the Internet wherever they are.
Users will have access through a combination of
terrestrial wireless and satellite transmissions.
One of the main benefits of UMTS is its speed.

10. UMTS Architecture
• A UMTS network consist of three interacting domains; Core Network
(CN), UMTS Terrestrial Radio Access Network (UTRAN) and User
Equipment (UE).
Core network:
• The main function of the core network is to provide switching, routing
and transit for user traffic.
• Core network also contains the databases and network management
functions.
• The basic Core Network architecture for UMTS is based on GSM network
with GPRS.

11. UMTS Architecture

12. UTRAN:
• (UMTS Terrestrial Radio Access Network), It provides the air interface access
between the core network and the User Equipment.
• The UTRAN contains the base stations, which are called Node Bs, and Radio
Network Controllers (RNC).
The functions of Node-B:
• Modulation / Demodulation
• Error Handing
The functions of RNC:
• Radio Resource Control
• Admission Control
• Channel Allocation

13. User Equipment:
• This includes mobile phones and computers which are connected to the internet.
UMTS went live as a network for the first time in Japan in 2001.
Austria had its own network two years later.
A handful of other European countries joined the UMTS bandwagon in the next
two years, with South Africa and a few other African countries soon following
suit.
The U.S. has employed UMTS networks in several large cities, and the number is
steadily growing.

14. Indian Telecom Software Industry
• Wipro, which posted a turnover of Rs 4,631 crore,
growing at 12% from last year and garnering a
market share of around 17.2%. A part of its growth
is attributed to the five-year contract that it has
won from Atheeb Telecom.
• Tech Mahindra came second, posting a 3% growth.
Its revenue stood at Rs 4,400 crore. The company
has bagged major deals to provide customer care
services to a service provider in India, which fired
up its revenue for this year.

15. Indian Telecom Software Industry
• TCS, the third player in the rankings, posted a
growth of 3.1%, posting a revenue of Rs 4,365
crore. The vendor was awarded major deals
from government's SWAN (state wide area
network) project last year, a project that
attributed much to its success.
• The need for software services within the
telecom sector has been steadily increasing over
the years, especially with the demand for
telecommunication services.

16. Indian Telecom Software Industry
• Spending in the mobile service segment will increase
each year as CSPs (Communication service
providers)prepare to support mobile data growth and
content based services. This is being driven by the
availability of smartphones, the completion of 3G
RAN upgrades and a rapid growth of subscribers
signing long term contracts for data services.
• The main factors for the expected growth of the
network management services, are the expected
growth in mobile data and broadband services,
emergence of new mobile technologies, continuing
fierce competition and network transformations.
