Group Paging Optimization For Machine-Type-Communications
Résumé
Machine-Type-Communication (MTC) is a promising
service of the envisioned 5G mobile networks. However,
deploying a massive number of MTC devices in these networks
remains a challenge due to the overload that may appear at
the Radio Access Network (RAN), hence degrading the Quality
of Services (QoS) for both MTC and Non-MTC devices. One
of the methods used to address the congestion’s problem in
RAN is Group Paging (GP), wherein a single message is used
to activate a group of devices. Whilst the GP method has several
advantages, its performance quickly decreases when the number
of MTC devices increases. In this paper, we devise a new method,
namely Traffic Scattering For Group Paging (TSFGP) to improve
the performance of the GP method for massive deployment of
MTC devices. Numerical results demonstrate that TSFGP highly
improves the performance of GP in terms of several performance
metrics, such as success probability, collision probability, and
access delay.
