Summary

Recommendation ITU-T G.1028.1 provides guidelines concerning key aspects impacting end-to-end performance of carrier-grade (in opposition to over-the-top (OTT) approaches, which are outside of the scope of this Recommendation) conversational video services over long-term evolution (LTE) networks, also known as video-telephony over LTE (ViLTE), as defined by Global System for Mobile communications Association (GSMA). It identifies the preconditions for an optimally operating ViLTE network and provides remedial measures that operators can leverage to address the associated impact of quality of service (QoS) degradations in the LTE network.
