Full Description
The present document outlines the process employed by TC TETRA Working Group 1 in generating user requirementsin general, and the methodology used for creating User Requirements Specifications (URSs) for Release 2.1 inparticular. It also covers the process of identifying interdependencies, which is considered important for ensuring thatvarious stand-alone URSs fit together into an integrated and coherent URS for TETRA Release 2.1 as a whole.The present document is applicable to the specification of TETRA Release 2.1 equipment.
NOTE: Some of the parts may stay as TETRA Release 2, but are part of the present set of URSs.
Each of the work areas of the TETRA Release 2.1 programme is covered by its own stand-alone URS. The URSs wereproduced by the membership of WG1, who are responsible for capturing and defining user requirements for TETRA.
