3. Introduction

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.

RNC INTERFACE

6. Critical functions of RNC
• Mobility management
• Power control
• Soft and softer handovers
• Link maintenance
• Traffic concentration
• Support of mobile services

7. Mobility management
• Physical location of users
• Subscriber location
• Call processing
• SMS
• Basic mobile services

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. Soft and Softer handovers
It allows two or more users to
communicate simultaneously with two
or more cells in two or more base
stations

11. Advantages
• Fewer lost calls
• Power controls
• Increase quality of services
Disadvantages
• Needs additional hardware resources

12. Link maintenance
• Fault localization
• Reconfiguration of RNC and reconfiguration
support for Node B
• Software updates in RNC and Node B

13. CONCLUSION
• RNC is a important network element in 3G
wireless network.
• It controls over BTS(base transceiver stations).
• Backbone of wireless network.
