Cloud computing in telecommunication

  1. 1. Using cloud computing to integrate multiple NODE B throughRNC in a 3G network ARPIT MISHRA MTECH(EXTC)405 UNDER THE GUIDANCE OF : PROF.RUKHSANA KHAN
  2. 2. What is CLOUD COMPUTING??
  3. 3. IntroductionNode B which had to be configured earlierthrough RNC one by one, can be managedsimultaneously with the help of cloudcomputing which works on a common serverand, henceforth if one NODE B is configuredthen all other NODE B which are connected tothe same RNC via the CLOUD could beconfigured simultaneously
  4. 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. 6. 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.
  7. 7. 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.
  8. 8. Power Amplifier Unit – HPA• Amplifies RF signals• Reports temperature• Provides overcurrent, over temperature, overpower, and over standing wave protectionsDuplex 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
  9. 9. 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
  10. 10. Control Clock & Switch Board (CC)It has Ethernet switching function and supports the data switching betweenservice 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.
  11. 11. 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
  12. 12. 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.
  13. 13. 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.
  14. 14. Layers
  15. 15. Use of Cloud Computing in Telecom• All function entities in hierarchical layers of telecomnetworks used to run on dedicated servers.• With cloud computing, these servers can now belocated in the cloud.• The hierarchical layers of telecom networks willdisappear.• All functions entities of telecom networks can bedynamically created, allocated, de-allocated, movedand removed from virtual machines in the cloud.• Benefits includeto scale telecom services on demandto improve reliability and availabilityto efficiently use infrastructure
  16. 16. FLOWCHART
  17. 17. 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 Use of Telecom Networks in Cloud Computing Use of Cloud Computing in Telecom Networks
