Core network aspects                                            1


            PE-FE       Policy Enforcement Functional Entity

            TAA-FE      Transport Authentication and Authorization Functional Entity
            TLM-FE      Transport Location Management Functional Entity

            TRC-FE      Transport Resource Control Functional Entity
            TRE-FE      Transport Resource Enforcement Functional Entity

            TUP-FE      Transport User Profile Functional Entity

            4.3     Functional blocks
            A-MMCF MMCFs as they relate to the network providing access to the UE and to the lower tunnel end-point

            C-MMCF MMCFs as they relate to the mobile subscriber's home network and to the upper tunnel end-point
            MMCF        Mobility Management Control Functions
            NACF        Network Attachment Control Functions

            RACF        Resource Admission and Control Functions
            SCF         Service Control Function

            TF          Transport Functions
            NOTE – The TF are sub-components of the access transport and core transport blocks respectively. No functional entities
            are specified within the TF themselves.

            6       Architecture model and concepts

            6.1     General concepts

            Figure 1 shows the incremental high-level functional architecture required for mobility management and
            control in the NGN transport stratum. Details of the general NGN architecture have been omitted to bring
            out the relevant points.
