Khondakar Mashiur Rahman University of Information Technology and Science ID : 060561 Program : M.Sc. in Telecommunication 2 Abstract The main objective of this study was to analyze the feasibility of migration from GSM Technology to UMTS technology. To accomplish the study at first the basic features of both GSM and UMTS has been explained. To make the study more effective and practical, a GSM operator was searched for. Teletalk started their GSM Network operation with Phase 2+ way back in April, 2005 and it is still continuing with the same technology. With growing demand in the market it is seriously contemplating to migrate into Release 3 (UMTS). The migrated system will definitely provide many advantages like addition of new applications video stream taking advantage the high bandwidth of 3G technology. But, there is other side of the coin too. First of all, it involves lot of investment. Then comes the cost of the 3G Mobile Station. Teletalk is also skeptical about the increase in ARPU with these added benefits offered to the subscriber. All such issues have been duly taken care in this study one by one. The other issue popped up regarding introduction of UMTS is whether to introduce the service globally through out the network or to introduce it on an island basis and then expand its territory in phases. All the pros and cons of such strategic decisions have been analyzed in the process. Along with that the technical hitches that might come in migrating to 3G services have been taken care in details. Finally a recommendation has been given for Teletalk about the strategic decision it should take at the moment regarding its migration to UMTS. 3 Contents Introduction ……………………………………………………………………….

BSS and NSS part the system has been migrated in 3G Migration from 2.5G towards 3G would be based on the following steps: 1. Migration path from GSM/GPRS to 3G network 2. Migration of GSM network architecture into 3G network architecture. 3. Migration of GSM Technology into 3G Technology. 4. Migration of GSM Radio Access network into 3G Radio Access network. 5. Migration of GSM signaling system into 3G signaling systems 6. Migration of GSM network planning into 3G network planning. 3G Teletalk Cellular Mobile system has been design where both GSM BTS & UMTS Node B, GSM BSC & UMTS RNC, GSM Network Switching Subsystem (NSS) & UMTS Network Switching System (NSS) will use the same platform. UMTS Network Switching System will design for both Circuit Switched (CS) domain for speech, video telephony, real-time data transfer & Packet Switched (PS) domain for non real-time data transfer. Migrated 3G system of Teletalk will provide following services: Video on Demand Game on Demand Video Telephony Multimedia Applications Tele-shopping Electronic newspaper with image and sounds Tele-Banking financial services Database information services Email Voice Data rate = 384kbit/s for Macro cell 6 Chapter – 1 Migration Path 1.1. GSM Positioning of Teletalk The second generation of cellular services (2G) of Teletalk Bangladesh Limited as characterized by the GSM standard is a TDM-based technology. GSM run over Plysynchronization Channel (PDH)/Synchronization Channel (SDH) access networks, relying on a wide variety of wire line and wireless transport solutions. The present positioning of Teletalk in GSM evolution path is shown in Figure 1.1. Fig. 1.1 GSM concepts with Teletalk Position General Packet Radio Service (GPRS): The relatively new 2.5G (GPRS) data service is still very much a TDM-based technology, providing an interim solution. 1.2. Teletalk Migration from GSM to 3rd Generation (3G) WCDMA technique is the standard modulation technique for 3G Radio Access Network. WCDMA technique is appropriate for migration from Global System for Mobile Communications (GSM)/ General Packet Radio Service (GPRS) to Third Generation (3G). According to following diagram (Fig. 1.2) Teletalk has the choice to slowly evolve along a migration path toward the original objectives of 3G to obtain the smoothest possible transition from the 2nd to the 3rd generation of mobile communications [4]. The cell parameters of 3G are Radius = several kilometers (according to Antenna NodeB parameter set) Transfer rate = 384 kbit/s Mobility = 120 km/h or high 500 km/h Fig. 1.2 3G Migration Path 7 CDMA / WCDMA: CDMA is Code Division Multiple Access. WCDMA stand for Wideband Code Division Multiple Access. WCDMA does not assign a specific frequency to each user. Instead every channel uses the full available spectrum. Individual conversations are encoded with a pseudo-random digital sequence. Direct-sequence CDMA permits multiple users to access a single radio frequency carrier by allocating a discrete code to each. This code is used to spread the user’s data stream over a wide bandwidth for transmission over the radio link. The receiver uses the appropriate code to “dispread” the user’s required signal to reproduce the original data stream. The use of codes to distinguish individual channels also allows adjacent base stations to use the same carrier. In all cases, for bi-directional communication, separate radio frequency carriers are used for uplink (mobile station to base station) and downlink (base station to mobile station). 1.3. Advantage of 3G over 2.5G Migration to 3G Mobile System has got the following advantages: Migration based on GSM core network & core network protocol. Migration based on GSM core network & as core network protocol will be similar. Save GSM investment Reuse of GSM supplementary services. PS – packet switch network as a result easy to compatible with LAN, WAN 3G is a path to migrate to 4G. 144 Kbps- user in high-speed motor vehicles can speed up to 500 km/hour 384 Kbps- pedestrians standing or moving slowly over small areas speed up to 120 km/hour 2 Mbps in low range

  • Telecommunications in Bangladesh
    Telecommunications in Bangladesh The liberalization of Bangladesh’s telecommunications sector began with small steps in 1989 with the issuance of a license to a private operator for the provision of inter alia cellular mobile services to compete with the previous monopoly provider of telecommunications services the Bangladesh Telegraph and Telephone Board (BTTB). Significant changes in the number of fixed and mobile services deployed in Bangladesh occurred in the late 1990s and the number of services in operation have subsequently grown exponentially in the past five years. The incentives both from government and public sectors have helped to grow this sector.It is now one of the biggest sector of Bangladesh. As a populous country, it's huge market has attracted many foreign investors to invest in this sector The telecom sector in Bangladesh is rapidly emerging. Bangladesh Telecommunication Regulatory Commission (BTRC) is the regulatory authority for this sector, overseeing licensing, policy etc. Calling Code: +880 – SubCodes Telecommunication Sector of Bangladesh: At a Glance There is many ups and down in the mobile phone industry in Bangladesh. At present there are six mobile operators in our country. According to the number of subscribes and profitability Grameen phone Ltd is in the top position among six operators. Except teletalk though their local names are Grameenphone, Banglalink, Robi, Airtel, Citycell but their main companies are the world’s famous and big organization. They have invested a lot and also they have more plans for investment. There is no doubt that their key objective is to earn profit. Government should create an environment and principles for profit.
