The general idea in UMTS is to harmonise the CN with GSM/GPRS as much as possible. This can be done since there is no major difference in how subscribers or charging are handled in both systems. Therefore, CN is constituted of a Circuit Switched (CS) domain and a Packet Switched (PS) domain which have the same main elements as is GSM/GPRS beside the CN common elements.The biggest change is in the UMTS Radio Access Network that introduces several new functions and a totally new air interface. The Radio Access Network is controlled by a Radio Network Controller (RNC), unlike the Base Station Controller (BSC) in a GSM network. In the 3GPP specification, the WCDMA BTS is referred to as Node B.

WCDMA Radio Access Network (WCDMA RAN)WCDMA RAN consists of one or more Radio Network Subsystem (RNS) where each RNS is constructed by a Radio Network Controller (RNC) and its controlled Node Bs. The main function of WCDMA RAN is handling all radio-related functionalities and managing radio resources in a 3G network. In addition, WCDMA RAN also handles telecommunication management for Circuit-switched and Packet-Switched traffic in a 3G network.The standardised interface between RNCs is called Iur, and interface RNC – Node Bs is called Iub.
Core NetworkCore Network (CN) is responsible for routing calls, data connections or other defined services to external network as well as handling user mobility.RAN interface toward Switching Core Network (SCN) is called Iu-CS, and it is implemented by connecting RNC to MSC Server (MSS) for control plane and to Multimedia Gateway (MGW) for user plane.RAN interface toward Packet Core Network (PCN) is called Iu-PS, and it is implemented by connecting RNC to Serving GPRS Support Node (SGSN).RAN interface toward Cell Broadcast Center (CBC), for Cell Broadcast Service (CBS), is called Iu-BC.RAN interface toward Positioning Center (PC), for Location Service (LCS), is called Iu-PC. It is implemented by connecting RNC to Standalone SMLC (SAS).NSN also provides alternative solution for LCS, which is implemented by connecting RNC directly to A-GPS server. For this solution, the position calculation is done by RNC. The proprietary interface toward A-GPS server is called A-GPS Data Interface (ADIF)

Operation Support SystemOperations Support System (OSS) is common for both 2G and 3G networks. The same management system is used for managing both the network and the services provided. In the NSN 3G solution, NetAct Framework is used for this task. The O&M interface toward OSS, called Network Interface for 3rd Generation Network (NWI3), is a CORBA based interface.

3GPP TS 25.401
The following are RAN functionalities defined in 3GPP specification number TS 25.401. RAN may have more functions in newer release.
1. Transfer user data. This function provides user data transfer capability across the UTRAN between the Iu and Uu reference points.
2. Functions related to overall system access control (e.g. admission control, congestion control, system information broadcasting, etc.)
3. Radio channel ciphering and deciphering. This function is a pure computation function whereby the radio transmitted data can be protected against a non-authorised third-party.
4. Functions related to mobility (e.g. handover, SRNC relocation, positioning, NAS node selection function, shared network access control, etc.)
5. Functions related to radio resource management and control6. Synchronisation7. Functions related to broadcast/multicast services8. Tracing. This function allows tracing of various events related to the UE and its
activities.9. Volume reporting. This function is used to report the volume of unacknowledged data
to the CN for accounting purpose.10. RAN information Management. This function is a generic mechanism that allows the
request and transfer of information between two RAN nodes.11. Functions related to MBMS

Some functionalities in handling packet data traffic are shifted from SGSN to RNC, e.g. Radio Protocol to IP conversion, Ciphering and Compression. Another packet data handling function, i.e. GTP tunnelling is implemented between RNC – SGSN, besides SGSN –GGSN.The ciphering is done in RLC layer of radio interface protocol, while IP packet compression is handled by PDCP layer. The RAN also has mobility concept which is implemented by UTRAN Registration Area (URA) to support packet data operation.

Optimizationand Tailoring
The goal of Radio Resource Management (RRM) is to ensure that the radio network capacity is used as efficiently as possible, i.e. radio access network offers high capacity, maintains the planned coverage area and the required quality of service. In WCDMA, the radio resources are defined in terms of transmission power, received wideband power, logical codes, BTS HW, Iub/Iur transport, and RNC HW.To achieve the goal, RRM algorithms are implemented on the RAN Network Elements. They are:
• Cell-based algorithms, i.e. Admission Control (AC), Packet Scheduler (PS), Load Control (LC) and Resource Manager (RM).
• Connection-based algorithms, i.e. Power Control (PC) and Handover Control (HC)In case of HSPA connection, the packet scheduler is shifted to Node B

Upgraded or downgraded
SGSN or UE can request the RAB reconfiguration procedure if there is a need to modify the characteristics of a RAB service. To the RAN the reconfiguration is triggered by the CN with a RAB Setup message requesting reconfiguration of the existing RAB. The following RAB parameters can be changed for the interactive and background traffic class RABs:
• Traffic class interactive <-> background • Maximum bit rate (UL/DL) • Change of Traffic Handling Priority (THP) of an interactive RAB • Change of Allocation and Retention Priority (ARP)
RNC reconfigures the RNC and BTS with the new RAB/SPI parameters after receiving the RAB reconfiguration request from CN.

The new NSN OSS product architecture provides a lot of benefits to the service provider. The separation of the element management from network and service management allows for fast adaptation to new network technologies and new releases of network elements. This kind of architecture is capable of supporting any combination of network technologies. The main principle is that current and new systems and applications can co-exits smoothly in the same network.
Highlights of the NetAct Framework:1. 3rd party tools: Building blocks allow the use of 3rd party products as an integrated part
of OSS.2. Common Network Topology: Access to OSS data is available through open interfaces.
This enables the integration to other OSS/IT systems.3. The use of a CORBA (Common Object Request Broker Architecture) based message
bus allows peer-to-peer communication within the OSS.4. Common WEB-GUI (Graphical User Interface):
• user access via Web interface• application location transparent to the users• all user interface applications work on network level
5. Management applications are developed separately as system components which are based on operator processes.

The NetAct solution supports the capability to plan the RAN with NetAct Planner or a 3rd
party planning tool. The plan is transferred to NetAct electronically and the planned parameters, settings and software are downloaded to the actual network equipment.Storing the plan for later use is also possible.
The main advantages of the NSN tools for RAN network development are:• Faster planning and implementation of network coverage provides for an early launch
of service.• Less manual work and site visits are required to put parameters into network
elements. This results in fewer errors and an improved effectiveness.• Optimised infrastructure investments and improved network quality can be achieved
by analysing the network behaviour, performance and usage.
