Node B equipment in 3G networks were previously configured individually through the RNC. Using cloud computing, multiple Node B's can now be managed simultaneously through a common server. When one Node B is configured, all other Node B's connected to the same RNC via the cloud are also configured at the same time. This allows for faster and more efficient management of network equipment.

2. What is CLOUD COMPUTING??

3. Introduction
Node B which had to be configured earlier
through RNC one by one, can be managed
simultaneously with the help of cloud
computing which works on a common server
and, henceforth if one NODE B is configured
then all other NODE B which are connected to
the same RNC via the CLOUD could be
configured simultaneously

4. • Cloud computing refers to
– the applications delivered as services over the
Internet
– the hardware and systems software in the data
centers that provide those services.
• The services are referred to as Software as a
Service (SaaS).and IaaS (Infrastructure as a
Service) or PaaS (Platform as a Service)

6. SYSTEM ARCHITECTURE

7. RNC (Radio Network Controller)
• The Radio Network Controller (or RNC) is a
governing element in the UMTS radio access network
(UTRAN) and is responsible for controlling the Node
Bs that are connected to it.
• The RNC carries out radio resource management,
some of the mobility management functions and is the
point where encryption is done before user data is sent
to and from the mobile.
• The RNC connects to the Circuit Switched Core
Network through Media Gateway (MGW) and to the
SGSN (Serving GPRS Support Node) in the Packet
Switched Core Network.

8. NODE B
• Node B is a term used in UMTS equivalent to the BTS
(base transceiver station) description used in GSM.
• It is the hardware that is connected to the mobile
phone network that communicates directly with
mobile handsets. In contrast with GSM base stations.
• Node B uses WCDMA/TD-SCDMA as the air
interface technology.
• As in all cellular systems, such as UMTS and GSM,
the Node B contains radio frequency transmitter(s) and
the receiver(s) used to communicate directly with
mobile devices, which move freely around it.
• In this type of cellular network, the mobile devices
cannot communicate directly with each other but have
to communicate with the Node B.

9. Power Amplifier Unit – HPA
• Amplifies RF signals
• Reports temperature
• Provides overcurrent, over temperature, overpower, and
over standing wave protections
Duplex Filter Unit – DFL
• Provides transmission/reception combination and
dividing/splitting functions for RF signals
• Provides transmit/receive RF channel filtering
• Provides the low noise amplifier (LNA) function
• Provides transceiver unit with the LNA alarm reporting
function

10. Power Module – RPW
• Power modules can be divided into AC and DC power
modules, that is, RPW AC/DC. If AC power supply is
used, the RPW AC is configured. If DC power supply is
used, the RPW DC is configured. The RPW provides the
following functions:
• Coverts AC/DC power supply
• Provides the transceiver unit with under voltage,
overvoltage, and overcurrent alarms

11. Control Clock & Switch Board (CC)
It has Ethernet switching function and supports the data switching between
service flow and control flow in the system.
• It handles Iub interface protocols (NBAP, SSCOP, and ALCAP).
• It monitors, controls, and maintains base station systems.
• It manages the versions of board software and programmable logic devices
in the system, and supports local and remote version upgrade.
• It monitors the working condition of the boards in the system.
• It synchronizes external reference clocks.
• It generates and distributes the clock signals required by individual parts
in the system.

12. Fiber Switch Board (FS)
Interface introduction:
• Tx0/Rx0 - Tx5/Rx5: It provides the optical interface that
connects with RRU.
• Board functions.
• It switches baseband I/Q data. It provides the interface
between BBU and RRU

13. Site Alarm Board (SA)
• SA Board functions.
• It supports alarm control and speed control of up to nine
fans.
• It provides signal monitoring and interface lightning
protection for the shelf at which it is located.
• It provides six input dry contact interfaces and two
input/output dry contact interfaces.
• It provides eight E1/T1 interfaces.

14. CLOUD COMPUTING
• a model for enabling convenient, on-demand
network access to a shared pool of configurable
computing resources (e.g., networks, servers,
storage, applications, and services) that can be
rapidly provisioned and released with minimal
management effort or service provider interaction.
• Cloud Computing makes computer infrastructure
and services available "on-need" basis.

15. Layers

16. Use of Cloud Computing in Telecom
• All function entities in hierarchical layers of telecom
networks used to run on dedicated servers.
• With cloud computing, these servers can now be
located in the cloud.
• The hierarchical layers of telecom networks will
disappear.
• All functions entities of telecom networks can be
dynamically created, allocated, de-allocated, moved
and removed from virtual machines in the cloud.
• Benefits include
to scale telecom services on demand
to improve reliability and availability
to efficiently use infrastructure

17. FLOWCHART

18. CONCLUSION
• Cloud computing is the future trend of the world-wide IT
industry.
• Telecom networks are evolving quickly to broadband
wireless IP networks with emergence of LTE/SAE.
• Two aspects of integration of cloud computing and telecom
networks
