Summary

Call handling is an important aspect of cellular mobile voice service user experience. Call handling is executed end-to-end by the access and non-access stratum of the network (i.e., global systems for mobile communications (GSM), code division multiple access (CDMA) or universal mobile telecommunications system (UMTS)).

To enable regulators and operators measure call handling of a cellular mobile voice service for benchmarking and compliance, Recommendation ITU-T E.807 defines five parameters, describes the methodology in accessing them, and provides guidance targets.

These can benefit a regulator, stakeholder or any interested party to independently measure and report on delivered service user experience.
