This chapter presents the architecture of the Evolved 3GPP system, as it corresponds to the 3GPP's stage 2 specifications: that is, the arrangement of functional entities (which may, but need not always correspond to network nodes) and reference points between them. Due to the inherent complexity and variety, this is done in steps: first an overall picture is given; then the evolved radio access network and evolved core network are discussed; finally the architectures for roaming and interworking cases are presented.
