This paper shows a delay probability of some traffics transmitted by each MT (Mobile Terminal) in a time slot in terms of VBR (Variable Bit Rate) traffic, analyzes that and proposes a generalization over new OFDM-based system to make up for the fault of existing WCDMA system. When a channel error exists, an average delay time processing in a time slot is analyzed and a generalization according to a retransmission is proposed. The authors analytically evaluate the performance via simulations and know that a delay probability goes the least by the optimization of a threshold according to MTs accessing to a system.
