Decision Point of AAL2 Multiplexing for Voice and Data Services in 3G WCDMA Network
نویسندگان
چکیده
To predict AAL2 multiplexing performance, we derived bandwidth gain analytically using discrete Markov chain model for voice service and validated these results with a simulation. And we also performed detailed simulation for voice and data services in a concentrator. Based on the analysis, we find that there is no major benefit of AAL2 multiplexing in a concentrator. The benefit of AAL2 multiplexing in Iub for data services is much less than that for voice service. The results also indicate that end-to-end application-level performance must be incorporated in all development phases and the benefit of AAL2 multiplexing depends heavily on the traffic load.

Performance Evaluation of an AAL2 Link Transmission Scheme for Voice and Data Packets in BS-BSC Links
An AAL2 link transmission scheme is considered as a promising bandwidth-efficient voice/data transmission method in BS-BSC links of third generation radio access networks. To guarantee low delay requirement of voice traffic, voice delay restriction methods are introduced in the AAL2 link transmission scheme. That is, a timer is used in the loading of voice ATM cell payload for limiting cell pac...

The focus of this paper is the performance of ATM/AAL2 as a transport technology for Universal Terrestrial Radio Access Network (UTRAN) in UMTS/IMT-2000 setting. In this work, we propose an analytical model for the transparent multiplexing and transport through UTRAN of several voice channels onto a single AAL2/ATM VC. We investigate the queue building up at the AAL2 multiplexer in order to der...
متن کاملAnalysis of Sub-Carrier Multiplexed Radio Over Fiber Link for the Simultaneous Support of WLAN and WCDMA Systems
The present third generation (3G) wireless technology can provide data oriented applications. However, the bit rate is limited to around 2 Mbps with limited mobility. Today, more applications demand high data rate and reasonable mobility. Therefore, by integrating 3G cellular system and wireless local area network (WLAN), there is a potential to push the data rate higher. This integration means...

Third-generation (3G) Wideband Code Division Multiple Access (WCDMA) network is an evolutionary network which supports services from circuit-based voice service to high and low rate packet-based data services. Unlike the voice oriented second-generation (2G) service, the 3G network is enhanced to support services with different data rate, different asymmetry, and different coverage. We thus nee...
