The present document outlines the process employed by EPT Working Group 1 in generating user requirements in general@ and the methodology used for creating URSs for Release 2 in particular. It also covers the process of identifying interdependencies@ which is considered important for ensuring that various stand-alone URSs fit together into an integrated and coherent URS for TETRA Release 2 as a whole. The present document is applicable to the specification of TETRA Release 2 equipment. Each of the work areas of the TETRA Release 2 programme is covered by its own stand-alone URS. The URSs were produced by the membership of WG1@ who are responsible for capturing and defining user requirements for TETRA. TETRA Advanced Packet Service (TAPS) has already been approved by EPT and is therefore not covered by these URSs.
