Question: In a known cell scenario, what is the minimum required rate of correct RRC (Radio Resource Control) re-establishments within the specified Re-establishment delay (TRE-ESTABLISH) of less than 1.9 seconds?
Option 1: At least 75% with no additional delay tolerance
Option 2: At least 80% with a possible extension to 2 seconds under heavy load
Option 3: At least 90% with the specified delay (TRE-ESTABLISH) of less than 1.9 seconds
Option 4: Exactly 95% without any tolerance for additional delays
Explanation: This question assesses understanding of RRC re-establishment requirements in known cell scenarios, specifically focusing on the minimum success rate within a given time frame. Option 3 is correct because it accurately reflects the requirement of at least 90% correct RRC re-establishments within the specified Re-establishment delay of less than 1.9 seconds, as per the provided telecom standard context. This highlights the importance of reliable and efficient network reconnection in practical telecom scenarios.
