Network controller for 3 g mobile and wireless

  1. 1. RADIO NETWORK CONTROLLER FOR 3G MOBILE AND WIRELESS NETWORK BY Sudhakar Shastri-14MCE1009
  2. 2. TABLE OF CONTENTS • Introduction • Radio Network Controller • RNC Interface • RNC Functions • Handovers • Conclusion
  3. 3. Introduction
  4. 4. RNC • The Radio Network Controller (or RNC) is a governing element in the Universal Mobile Telecommunications System UMTS radio access network (UTRAN) • It is responsible for control the Node Bs that are connected to it.
  5. 5. MGW-media gateway MSC-mobile switching center Serving GPRS support node-SGSN Gateway GPRS support node-GGSN RNC INTERFACE
  6. 6. Critical functions of RNC • Mobility management • Power control • Soft and softer handovers • Link maintenance • Traffic concentration • Support of mobile services
  7. 7. Mobility management • Physical location of users • Subscriber location • Call processing • SMS • Basic mobile services
  8. 8. Power control • Controls over transmitted power of the terminal and Base Stations • Less interference • Allows more no of users on same carrier Hence more capacity • Frequency reuse
  9. 9. Soft and Softer handovers It allows two or more users to communicate simultaneously with two or more cells in two or more base stations
  10. 10. Advantages • Fewer lost calls • Power controls • Increase quality of services Disadvantages • Needs additional hardware resources
  11. 11. Link maintenance • Fault localization • Reconfiguration of RNC and reconfiguration support for Node B • Software updates in RNC and Node B
  12. 12. CONCLUSION • RNC is a important network element in 3G wireless network. • It controls over BTS(base transceiver stations). • Backbone of wireless network.
