The article focuses on the shift from 3G to 4G technologies. A 3G technology is capable of peak data rates up to two mbps for stationary or walking users. The migration to 4G takes place in the 3G network because GSM operators have optimized their 2G core for data and still evolving their packet core for the 3G technology W-CDMA/HSPA. An important aspect in the transition is billing for the services running over the different network technologies.
