Dear Expert,
We face an issue related to drop VoLTE call continuously due to UE lost with good radio condition (vendor E//). It happened continuously at sometimes ( with some models: SAMSUNG SM-M205G/DS,SAMSUNG SM-N975F/DS...).
Example log trace 4G VoLTE E//. Cell has 14 drops VoLTE/ 74 attempt, all drops belong to 1 UE (SAMSUNG SM-M205G/DS).
1. Radio condition: RSRP ~ -95 dBm, RSRQ ~ -12 dB.
2. Time: Sometime but if occur it drops continuously.
3. Model: SM-M205G/DS
Included log celltrace, help me figure out root cause (parameter, device). Thank you very much.
