RNC INTERFACE

Critical functions of RNC

• Mobility management• Power control• Soft and softer handovers• Link maintenance• Traffic concentration• Support of mobile services

Mobility management

• Physical location of users• Subscriber location• Call processing• SMS• Basic mobile services

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

Soft and Softer handovers

It allows two or more users to communicate simultaneously with two or more cells in two or more base stations

Advantages

• Fewer lost calls• Power controls• Increase quality of services

Disadvantages• Needs additional hardware resources

Link maintenance

• Fault localization • Reconfiguration of RNC and reconfiguration

support for Node B • Software updates in RNC and Node B

CONCLUSION

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