ITU-T Recommendations

This Recommendation provides guidelines concerning the key aspects impacting end-to-end performance of managed voice applications over LTE networks and how they can be properly assessed using current elements of knowledge.

Some typical end-to-end scenarios are described, involving cases with LTE access at both sides of the communication, or with a different access technology at one side (wireless or wireline access). These scenarios are based on typical reference connections defined in this Recommendation, composed of various segments, including: terminal, wireless access, backhaul network, core network. Considerations regarding the sharing of the budget of some key parameters and the location where they can be assessed across these segments are provided.
