A case study into Finnish IMS implementation and verification: VoLTE

Abstract

Systematic testing approach to IMS features such as VoLTE, SMS over IP is crucial to ensure reliability, performance and maturity of such features before they are commercially available. This thesis introduces theoretical background of IMS infrastructure, VoLTE component and end to end signaling, and present Telia Finland’s IMS requirement as an example of how terminal configuration and testing should be carried out. The scope of the case study is limited to examples of configuration needed from mobile terminal side to support Telia Finland’s IMS network features and focus on the verification steps to ensure both the core functions and supplementary services performance are up to the standard of a commercial launch. Specifically, seven test cases were presented as example on how standard stationary and road testing should be carried out. As a result of the case study, testing limitations and methodology considerations are offered in thesis conclusion for future implementation of VoLTE features in Finland.
