【资料名称】:Best Selection for Operators starting LTE

【资料作者】:Deployment towards Voice Services

【资料日期】:2012

【资料目录和简介】:

— 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
operatorsshould take into consideration all the aforementioned
points.
