The Evolved 3GPP System (SAE/LTE) needs to be managed. Being an evolution of UMTS, the management should also evolve from UMTS. Reuse of existing UMTS management standard solutions has the following benefits:

• It is proven in operation;

• Minimizes both the standardization and product development efforts (i.e. cost and time);

• Provides a base on which more functionality can be developed (compared with starting from scratch);

• Shortens the time to market for LTE and SAE systems;

• Facilitates a seamless coexistence with UMTS management systems.

Complexity of the LTE network places new demands on the Operations and Maintenance of the Network. Therefore in parallel with reuse/evolve existing Management solutions, new revolutionary elements are needed (e.g. Auto-Configuration, Auto-Optimization, Information Model Discovery and P2P Interfaces).

Functionality is supported by use cases or other documented justification.

SA5 assessed reusing the UMTS management for LTE and SAE in order to decide which existing parts can be reused without change, which need changes and which cannot be reused at all.

The study resulted in decisions on management principles for LTE and SAE, e.g. the management architecture, auto-configuration and KPIs, P2P Interface for exchange of Inter Cell Parameters and Information Model Discovery.

Before completing TR 32.816 several implementation WIs had been stared by SA5 e.g.:

• E-UTRAN Network Resource Model (NRM) Integration Reference Point (IRP) UID_380036

• Self-Organizing Networks (SON) UID_390004

• EPC Network Resource Model (NRM) Integration Reference Point (IRP) UID_380037

Supporting Individual Members: Alcatel-Lucent, Ericsson, Huawei, Nortel, Nokia, Siemens Networks, T-Mobile.

The Evolved 3GPP System (SAE/LTE) needs reliable and efficient charging solutions. Being an evolution of UMTS, also the charging solutions need to evolve. Reuse of existing UMTS charging solutions has the following benefits:

• It is proven in operation;

• Minimizes both the standardization and product development efforts (i.e. cost and time);

• Provides a base on which more functionality can be developed (compared with starting from scratch);

• Shortens the time to market for LTE and SAE systems;

• Facilitates a seamless coexistence with UMTS management systems.

Functionality is supported by use cases or other documented justification.

SA5 assessed reusing the UMTS charging for the Evolved 3GPP System in order to decide which existing parts can be reused without change, which need changes and which cannot be reused at all.

TR 32.820 conclusions

Charging Requirements and Principles - no changes required.

Charging Architecture - modifications needed for the P-GW and thus the PCEF being in the visited network. Full PCEF with service-aware flow-based charging is located only in P-GW.

Charging Data and Protocols - changes required to the charging data to take into account the new information available due to the different mobility models. The scope of these changes is not large. Changes are also required to the Transferred Account Procedure (TAP) for subscriber charging in case of Local Breakout.

Implementation Work Item - under the Feature SAES UID_320005, a new Building Block UID_390010 (EPC Charging) covers the charging aspects of the Evolved Packet System (EPS).

Specification structure - existing charging TS 32.251 for PS-domain and TS 32.252 for WLAN should be extended for the EPS. Changes are needed to TS 32.240 charging architecture and TS 32.296 OCS architecture and corresponding enhancements of the charging protocols in TS 32.298 and TS 32.299.
