GSM to UMTS WCDMA Migration

To study the technology of 2.5G of Teletalk network and migrating it into 3G technology according to UMTS WCDMA method with coexisting of current GSM network by obtaining sufficient coverage over the entire service area to ensure that high quality voice service and high bandwidth of data service will be offered to the subscribers.BSS and NSS part the system has been migrated in 3^rd Generation. Please contact me for the full thesis- +88 01 79 52 53 54

Migration from 2.5G towards WCDMA UNTS :

• Migration from 2.5G towards wcdma umts would be based on the following steps:
• Migration path from Global System for Mobile /GPRS to wcdma umts network
• Migration of Global System for Mobile network architecture into 3^rd Generation network architecture.
• Migration of Global System for Mobile Technology into wcdma umts technology
• Migration of Global System for Mobile Radio Access network into 3G Radio Access network.
• Migration of Global System for Mobile signaling system into WCDMA signaling systems
• Migration of Global System for Mobile network planning into 3^rd Generation network planning.
• In future it can migrate to 4g

What is UMTS :

UMTS means Universal Mobile Telecommunications System. 3G technology Teletalk Cellular Mobile system has been design where both Global System for Mobile BTS & UMTS Node B, GSM BSC & UMTS RNC, GSM Network Switching Subsystem (NSS) & UMTS Network Switching System (NSS) will use the same platform. UMTS  means network switching system will design for both circuit switched domain for speech, video telephony, real-time data transfer as well as packet switched domain for non real-time data transfer.

Service of Migrated 3G Technology :

• Migrated 3G technology system of Teletalk will provide following services-
• Video on Demand based on 3g speed
• Game on Demand
• Video Telephony based on 3g speed
• Multimedia Applications based on 3g speed
• Tele-shopping
• Electronic newspaper with image and sounds
• Tele-Banking financial services based on 3g speed
• Database information services
• Email  based on 3g speed
• Voice based on 3g speed
• Data rate = 384kbit/s for Macro cell
