Implementing 4g/LTE capable of logging mobile users and sending them welcome messages
Abstract
The long-term evolution (LTE) has spread around the globe for deploying 4G cellular networks for mobile users. These days, it is gaining interest for new applications where mobile multimedia services can be of benefit to society.
Several new approaches and technologies are being considered as potential elements making up a more improved 4G mobile network, including radio network programmability and Application Programming Interfaces (APIs) following Software Defined Network (SDN) principles. Research on these improvements requires realistic and flexible experimentation techniques including real world experimentation, controlled and scalable evaluations whereas retaining backward compatibility with current generation systems.
In this project we present a test bed at CEDAT (ECE department) using srsRAN, and open source mobile Cell Broadcast Center (osmoCBC), which are open-source platforms for LTE implementation capable of logging mobile users and sending them welcome messages. The aim is to enable students, researchers and product developers have a comprehensive understanding of the performance and limitations of mobile communication networks. The purpose of sending welcome message is to enable reception of message over IP without circuit switch fallback of LTE since it is packet oriented only.
In the context of LTE, the test bed typically includes one User Equipment (UE), one base station (eNodeB), an Evolved Packet Core (EPC), a cell broadcast center (osmoCBC) and Cell Broadcast Entity. The implementation shows the 4G LTE network (eNodeB and EPC), and UE using srsRAN, establishes mobile user logging capability onto the 4G network and developing protocols that can send welcome messages to mobile users using osmoCBC.
