TRANSITION PATH TO IMT-2000 IN SERBIA
Well Developed GSM operators going WCDMA
The GSM and WCDMA evolution raises several critical questions for the operator: How can operators maximize and reuse current GSM assets? How can they deploy WCDMA while maintaining profitability in GSM? How do they best allocate investments between GSM and WCDMA infrastructures? How will users experience the new combined GSM and WCDMA services?

Seamless Network - Ericsson’s view on how existing GSM networks will evolve and interwork with WCDMA The evolution scenarios, operator needs and suggested solutions System evolution for GSM, the introduction of third-generation (3G) services and the integration of GSM and WCDMA to form a seamless network Evolution of GSM and WCDMA networks as a single, unified seamless network that shares core, transmission, radio and application resources. The seamless network ensures the most efficient use of GSM and WCDMA Seamless user experience – transparency of services to users Ensures operator’s investment protection in GSM/GPRS and re-use of 2G/2.5G equipment for WCDMA networks

Regulation in Serbia
Competion market, increasing the benefits in terms of price and QoS, is not yet regulated completely. New Telecom Act is approved in April, 2003, designed on the basis of EU legislation ( licensing, interconnection, transparent, objective and nodiscriminatory basis, open network provision on all hierarchical level, competion for the open market). New Act is not yet put into force, since the management board of NRA is not yet approved by the Parliament. Telekom Srbija ( incumbent) operates public fixed network and mobile network as well, with monopoly for fixed telephony until June, 2005. → liberalization allowing new players! No official anouncement has been issued for the IMT-2000 license, frequency bands are still occupied by other users.

REGULATORY AGENCY
Set-up future requirements in the overall telecom sector regulation process Analyse the data from mobile market survey and define needs and demands Put into force the new Telecom Act ASAP! Main priority is to remove measures that restrict competion Free the frequency bands for the IMT-2000 (UMTS) development Define the principles and methods for the licensing Define the preconditions of the licenses Define obligations related to the universal services Define the number of licenses, based on market potential Proceed with the licensing process!

Some key questions for 3G evolution/migration
Licensing 2GHz frequency band occupied Transmission network evolution both for core and access network to meet requirements for increased flexibility, capacity and availability Terminals availability covering GSM/GPRS/EDGE/WCDMA (handsets and PCMCI cards) Readiness of operator' organizations for 3G (resources, competencies...) s Evolution vs. migration CS & PS handovers Role of IMT-2000 in Corporate Social Responsibility: The responsibility of the state/government, vendors, operators and regulators to support new technologies bringing new dimension of communications.

Purpose of the Ericsson’s PreCommercial WCDMA/UMTS Systems
Use of WCDMA/UMTS pre-commercial trial for different kinds of load and interoperability testing in order to prepare the operator’s network for the fast 3G launch To give the opportunity to operators to: Build up competence and get hands on experience of IMT-2000 networks and services Implement and test end-to-end solution for a 3G system in compliance with 3GPP R99 specs Look into integration issues, e.g. billing and customer care Prepare for an early IMT-2000 launch - immediate transition to commercially ready-for-launch network Hold market events
