Answer Seizure Ratio vs Answer Busy Ratio

This page defines Answer Seizure Ratio vs Answer Busy Ratio and mentions difference between Answer Seizure Ratio and Answer Busy Ratio.

These terms are related to teletraffic engineering of mobile systems.

Answer Seizure Ratio

• The ratio between number of successful calls (answered) and total number of call attempts (seizure) is called answer seizure ratio.
• It is abbreviated as ASR.

Answer Seizure Ratio

Answer Busy Ratio

• It is the ratio of number of successful calls (answered) and the total number of busy calls.
• Answer Busy Ratio is abbreviated as ABR.

Answer Busy Ratio

➨Both ABR and ASR are measured over relatively short periods of time which is about 5 to 15 minutes.
➨Both Answer Seizure Ratio and Answer Busy Ratio are good indicators of instantaneous network congesiton.
➨Lower values of ABR and ASR indicates higher network congestion.
➨Higher values of ABR and ASR does not mean lower network congestion since calls may remain unanswered due to other reasons also.
