UTRAN (UMTS Terrestrial Radio Access Network) includes RNC(Radio Network Controller),Node B and UE. MSC (for CS services) and SGSN (for PS services) are part of the core network.
Iub interface - Between RNC and Node B
Iu interface - Between RAN and CN (Core Network). There is separate Iu interface for PS and CS CN.
Iur interface - Between 2 RNC
Uu interface - Air interface through which UE and Node B communicates. Connection from UE to Node B is called Uplink and from Node B to UE is called Downlink.
Serving,Controlling and Drift RNC
Each UE has a serving RNC and each Node B has a controlling RNC. Drift RNC comes into picture when UE moves and comes under the coverage area of other RNC and gets connected to it. RNC that provides Iu connection is called serving RNC.
RNC 1 - serving RNC for UE and controlling RNC for Node B 1&2
RNC 2 - drift RNC for UE and controlling RNC for Node B 3&4
I would say it UTRAN(for 3G) instead of RAN because RAN is very generic terms and can be used for 2G/LTE as well.
ReplyDeleteYou can mention Application protocol names as well along with it.
Yes,UTRAN would be better than RAN. I will be adding more information in it.Thanks for the comment.
