Abstract :
For most of the operators planning to start LTE deployment, recovering the cost of this expensive network is a big challenge that cannot be achieved without ensuring the continuity of voice services. In this paper, we studied and compared the possible solutions to add voice services on an LTE network which is mainly dedicated for high-speed data transfer. We concluded, in comparison to the advantages and disadvantages of the existing approaches that the One Voice approach is the target solution to meet the needed requirement. Having the support of all the famous operators and vendors, the choice of One Voice approach as a first alternative was obvious but, for the mid-term solution or backup solution the selection of CSFB approach from many operators was not clear. We proved that VOLGA approach is better than CSFB for many reasons, using less complex and less expensive handset whilst giving more comfortable user experience compared to CSFB approach. A key lesson can be learned from the existing technologies, CDMA and GSM, where the type of handset was one of the major factors of the GSM success. So before selecting the backup alternative operators should take into consideration all the aforementioned points.
