The ECP-541 certification targets network engineers tasked with the deployment, maintenance, and troubleshooting of Ericsson GGSN-MPG and GPG platforms within mobile core architectures. Candidates must master packet core signaling protocols, GTP-U and GTP-C tunnel management, and complex IP routing configurations inherent to Ericsson’s packet gateway nodes. The exam validates proficiency in hardware management, software upgrade procedures, and high-availability cluster operations. Proficiency in GPRS/UMTS charging mechanisms, traffic flow analysis, and policy enforcement via Gx and Gy interfaces remains critical. Technical expertise in analyzing system logs and resolving data path throughput issues ensures operational stability across high-capacity, multi-access packet core environments.
