FAULT RECTIFICATION

UMTSUMTS (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.

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.

UMTS Architecture

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

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.

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.

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.

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.
