GPRS challenges mobile network operators

摘要

General packet radio service (GPRS) networks are an example of the new challenges in the test field for network operators. GPRS is an important improvement on the path from second- to third-generation (3G) mobile communications systems. An overlay to existing global system for mobile communications (GSM) networks, GPRS lays the foundation for universal mobile telecommunication service (UMTS) and 3G systems that are based on packet-switched architectures.
