AAL2(AAL type 2)를 적용한 UMTS 핵심망에서 전송지연 제어 알고리즘

In this paper, we explained the AAL2 protocol of efficient voice transmission in the UMTS core network for interworking with wired and wireless communication. Particularly, in the UMTS system using AAL2 protocol, we proposed the dynamic Timer_CU control algorithm that enhances the delay characteristic by initial Timer_CU value. The proposed dynamic Timer_CU control algorithm with proportion of the amount of padding cell reduces AAL2 transmission delay with no effect on the link efficiency. From the result of simulation, dynamic Timer_CU control algorithm decrease transmission delay more than fixed Timer_CU control algorithm. Both algorithms are quite similar to link efficiency. In the future, when the IMT-2000 systems serve in earnest, this paper results are applied to performance elevation of voice traffic.
