LTE speech traffic estimation for network dimensioning

LTE voice application is based on packet IP which is known as VoLTE by GSMA. To estimate VoLTE traffic, the UTRAN voice calls need to correctly convert into full-IP traffic and impose with a correct LTE codec. The knowledge to estimate data rate requirements is very important for network planning & dimensioning. This paper provides a dimensioning approach for LTE network using the readily available UTRAN traffic data from the speech traffic perspective. The estimated traffic throughput requirement per eNodeB as well as overall LTE network cluster is presented and can be used to dimension the eUTRAN as well as IP Transport nodes.
