M. Paterakis et Ac. Cleary, ON THE VOICE-DATA INTEGRATION IN 3RD-GENERATION WIRELESS ACCESS COMMUNICATION-NETWORKS, European transactions on telecommunications and related technologies, 5(1), 1994, pp. 11-18
Mobile wireless communications, which includes cellular telephones, la
nd mobile radio, and personal communication systems, have experienced
enormous growth over the last decade. Data services represent a critic
al component of future wireless communications, but have received litt
le attention. While some attention has been given to specialized mobil
e data networks, less has been directed at the ongoing design of data
services in evolving digital cellular networks. In this paper we repor
t on the results of a simulation study which explores voice-data integ
ration performance in third generation wireless communication networks
. These networks are designed to provide access to broadband ISDN netw
orks for large numbers of mobile voice and data users. The primary goa
l of the paper is the development of multiple access transmission prot
ocols that will enable the voice and data terminals to efficiently sha
re the terminal to base station wireless channel. Reservation Random A
ccess (RRA) protocols are used for voice traffic, and multiple random
access contention protocols are used for data traffic. The RRA protoco
ls used enable the data terminals to precisely determine the end of vo
ice packet contention periods, therefore providing a natural separatio
n between voice and data contention. Such voice data integration mecha
nisms allow the voice contending terminals to resolve their contention
without any interference from the data terminals. Data contention res
olution does not degrade the voice performance. since it follows the v
oice contention resolution. The above approach is a promising alternat
ive to other existing proposals due to its superior data packet throug
hput-delay performance under steady state, and voice performance under
transient conditions. Our results show that dispersed voice and data
terminals can efficiently share a wireless channel.
