scope:

The present document defines a series of network performance metrics that are applicable to TETRA networks, whose measurement and reporting makes it possible to know the impact of adding new terminals or new infrastructure to an existing TETRA network. Network performance parameters, inherent within a network, include those, which affect to the quality of an "end-to-end" connection as experienced by a subscriber. A network performance parameter may be considered as a function of the operation of the elements involved to form a connection, network load, network signalling and the processing required to realize a connection.

Requirements on the measured values are outside the scope of the present document.
