Huawei Certified ICT Graduate (HCIG) Program Is One Of The Unique Programs Specially Aimed For Engineering Graduates Undergoing Their Engineering Course, Where Participants Get Trained & Certified By Huawei On Multiple Leading ICT Technologies including:

1. Core Network2. Wireless Telecom (2G/3G/4G)3. IP- Datacom (Routers, Switches, Security & Firewall)4. Networks ( Access, Optix & Microwave)5. Cloud Computing

1 CORE NETWORKObjectives• Grasp Basic Idea Of GSM System Such As Frequency Spectrum,

Frequency Reuse etc.

• Grasp The Structure Of GSM System And The Protocol Used

• Grasp Certain Numbers That Refer To BSS

• Grasp the 4 Kinds Of Channel Combination And Understand The Idea Of Multiframe

• Know Some Radio Techniques

• Get The Idea Of EDGE.

GSM SYSTEM OVERVIEW• The GSM system is a frequency- and time-division cellular

system, each physical channel is characterized by a carrier frequency and a time slot number

• Cellular systems are designed to operate with groups of low-power radios spread out over the geographical service area. Each group of radios serve MSs presently located near them. The area served by each group of radios is called a CELL

• Data for different users is conveyed in time intervals called slots , several slots make up a frame. This kind of technique is called Time Division Multiple Access (TDMA)

GSM DEVELOPMENT

Standard Protocol for GSM take effect

System was named as Global System for Mobile Communication

GSM system began to provide service in Europe(2G)

Provide services for the whole world

Micro Cell Technique is used in GSM system

MULTIPLE ACCESS TECHNIQUE

• Multiple Access Technique allows many subscribers to use the same communication medium.

• There are three kinds of basic Multiple Access Technique : FDMA , TDMA and CDMA.

• GSM system adopt FDD-TDMA (FDMA and TDMA together).

FREQUENCY REUSE• The frequency resource of mobile system is very limited.• The different Subscribers can use the same frequency in

different places.• The quality of communication must be ensured

OSI REFERENCE MODEL• In 1984 in order to aid network interconnection without

necessarily requiring complete redesign, the Open Systems Interconnection (OSI) reference model was approved as an international standard for communications architecture.

• The Open Systems Interconnection (OSI) reference model is a descriptive network scheme. It ensures greater compatibility and interoperability between various types of network technologies.

• The OSI model describes how information or data makes its way from application programmes (such as spreadsheets) through a network medium (such as wire) to another application programme located on another network.

WHY 7 LAYERS ?

In 1983, Day and Zimmerman laid down certain principles that were applied to

arrive at the seven layers can be briefly summarized as follows:

• A layer should be created where a different abstraction is needed.

• Each layer should perform a well-defined function.

• The function of each layer should be chosen with an eye toward defining

internationally standardized protocols.

• The layer boundaries should be chosen to minimize the information flow across

the interfaces.

• The number of layers should be large enough that distinct functions need not be

thrown together in the same layer out of necessity and small enough that the

architecture does not become unwieldy

OSI MODEL

TCP/IP REFERENCE MODEL

The Internet Protocol Suite (commonly known as TCP/IP) is the set of communications protocols used for the Internet and other similar networks.

It is named from two of the most important protocols in it:

The Transmission Control Protocol (TCP)

The Internet Protocol (IP), which were the first two networking protocols defined in this standard.

3 CLOUD COMPUTING

OBJECTIVES

• Introduction To Typical IT Environment

• Cloud Concept

• Deployment Models

• Understanding On Huawei Desktop Cloud

INTRODUCTION

• Cloud computing is a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications.

• In cloud computing, the word cloud (also phrased as "the cloud") is used as a metaphor for "the Internet," so the phrase cloud computing means "a type of Internet-based computing," where different services such as servers, storage and applications are delivered to an organization's computers and devices through the Internet

CLOUD SERVICE MODELS

There are mainly 3 service models given as:

1. Software as a Service (SaaS)

2. Platform as a Service (PaaS)

3. Infrastructure as a Service (IaaS)
