SA场景下,信令类的RRC建立成功率计算公式是()
A.RRCS_SRsignaling = (RRCSetupAttemptsignaling/RRCSetupSuccesssignaling) × 100% B.RRCS_SRsignaling = (RRCSetupSuccessservice/RRCSetupAttemptservice) × 100% C.RRCS_SRsignaling = (RRCSetupSuccesssignaling/RRCSetupAttemptsignaling) × 100% D.RRCS_SRsignaling = (RRCSetupAttemptservice/RRCSetupSuccessservice) × 100%
