2 Short Description VoLTE stands for voice over Long-Term Evolution. It is a combination of LTE and IMS technology which enables processing of digital packet voice service that is delivered over IP VoLTE course covers technical aspects of how voice is harnessed in LTE Networks by leveraging the IMS solution.this course would cover comprehensive information of VoLTE architecture, Standards, protocols, QoS, interfaces, interworking, SRVCC,T-ADS,Charging and Call flow. Objective Module 01: Introduction to VoLTE Module 02: EPS Overview Module 03: IMS Core for VoLTE Module 04 : PCRF/PCEF in VoLTE solution Module 05: Protocols in VoLTE SIP, Diameter, RTP, H.248,GTP,NAS Module 06 :VoLTE Subscriber Access, Authentication and Registration procedures Module 07: Application server Module 08: SR-VCC(Single Radio Voice Call Continuity) and T-ADS Module 09: Charging concepts Module 10 : VoLTE Call Flows Teaching Tools Slides Whiteboard Q&A (End of each module) Wireshark pcap traces Group discussion (Post lunch/each Day) Case study Screenshots of Vendors Products for configuration parameters (As Applicable) Target GroupTarget Group a) Telecom Professionals who are from LTE, EPC, 2

3 Radio, Core Network operations, engineering, planning verticals. * This training should also benefit working Engineers/Associates from CS Core Network & Packet Core domain who would like to learn VoLTE and upgrade their knowledge Prerequisite Basic knowledge of GSM, WCDMA, Core network, LTE, UMTS or telecom in general Assessment Pre-and Post-Assessment Questionnaire. Note: Participants are advised to go through Pre- Assessment test before the Course commences. Learning outcomes: Understand role of the LTE-Evolved packet core, Policy & Charging Control and IP Multimedia System (IMS) in LTE networks Chalk-out IMS and various nodes and how those nodes interact to deliver an end-to-end VoLTE call Summarize the key steps of pre-call operations including default bearer establishment and IMS registration Understand main steps of setting up a VoLTE call.
