Figure 1 Radio Network Overview
The Radio Network consists of the following parts:
Core Network
The Core Network (CN) provides call control as well as mobility for, and
localization of, the User Equipment (UE). The CN also interacts with the
RNC and provides support for network features and telecommunication
services. The CN handles both packet-oriented services, such as data, and
circuit-oriented services, such as speech.
RAN
The RAN provides the connection between the CN and the UE. The RAN
also comprises interfaces towards different management systems. The RAN
consists of the RNC and the RBS.
• The RNC interacts with the CN as well as the RBSs and manages radio
links. The RNC also controls mobility and optimizes the radio network
