Good understanding of call flows, network protocols, and mobility scenarios
Experience working with Qualcomm/Mediatek chipset-based devices is a plus.

3GPP Standards Requirements:
3GPP (3rd Generation Partnership Project) defines global standards for cellular networks like 3G, 4G (LTE), and 5G. Key specifications relevant to this role include:

5G NR (New Radio) Standards:

SA (Standalone) NSA (Non-Standalone) as per 3GPP Release 15+
VoNR (Voice over New Radio) for voice services in 5G SA
Carrier Aggregation to enhance data speeds and efficiency

4G LTE IMS (IP Multimedia Subsystem):

VoLTE (Voice over LTE) for seamless voice calls
IMS SIP-based call flows as per 3GPP TS 23.228, 24.229

Network Protocols Testing:

5G NR Call Flows - Defined in 3GPP TS 38.300, 38.331
Mobility Scenarios (Handover, Idle/Connected Mode) - 3GPP TS 36.331, 38.331

Understanding and working with these 3GPP specifications is crucial for efficient device testing, debugging, and ensuring compliance with global telecom standards.
