“SIP and Diameter Signalling” course focuses on signalling in EPC network. During the course core interfaces and signalling protocols with procedures and parameters are presented in details.
The course is intended for experienced network engineers, network tuning staff, EPC protocol stack developers, and anyone with network experience, who needs deep technical knowledge on functionality of EPC.
