Implementating a 4G LTE mobile communication Network Capable of Logging Mobile Users and Sending them Welcome Messages
Abstract
With the digital migration of technologies to full Internet protocol (IP) based networks that support
increased traffic volume, wider geographical coverage, speed etc.; many challenges are posed
requiring research and experimentation. 4G is a wireless mobile communication network that
widely uses circuit switched fall back to 2G or 3G for Voice and short message service (SMS)
because it is IP based. With the migration of technologies to IP it is necessary to do
experimentations to put off the need for fall back thus research on all the parameters involved
therein with an example being SMS.
Today, testbeds are an essential platform for experimental research and prototype development.
They enable researchers to test, validate and assess the performance of new technologies for
wireless networks. Open source software available online for students and researchers play a huge
role in implementation of testbeds involving Long Term Evolution which testbeds are essential for
experimental evaluation as well as for product development. These open source software include
srsRAN, Open Air Interface (OAI); in our context srsRAN, is used to implement an open source
4G software radio suite.
