Supervisor virtual machine for VoLTE service on a cloud environment
| Resumo: | With the continuing growth of Voice of Long Term Evolution (VoLTE) networks, coupled with the need of Mobile Operators to reduce maintenance costs, Cloud Service deployment is becoming a common application. This study was designed to create a method capable of improving the Operations and Monitoring activities of a VoLTE service that is deployed on a Cloud platform. In this study, we present contents referring to the constituent elements of a VoLTE network, and we review in detail the features of the Telephony Application Server. For this study, TAS used was the Open TAS. Also included in this study is a generic explanation of Cloud Openstack’s behavior. The presented method implies the creation of a virtual machine Supervisor and its deployment in Cloud. This virtual machine is capable of establishing SSH connections with open TAS to extract the Clear Codes report, which identifies the state with which calls were terminated for analysis. The virtual machine contains defined limits, which check if they have been exceeded. If this a limit is excited, the virtual machine notifies the system operator of an incident. This study presents the possibilities of implementation in a Cloud environment, to improve and automate Operations and Maintenance functions in the Telecommunications network. |
