Introduction
The present document has been written to satisfy the identified need for interworking between TETRA and the Mission
Critical applications specified by 3GPP, to permit communications between users and groups operating on the two
system technologies. It provides solutions to the considerations documented in ETSI TR 103 565-1 [i.1], which studied
the issues for interworking between the two technologies. Additionally, it provides an overview of the business
relationships between operators of the two technologies, and describes applicable deployment scenarios.
Terminology used in the present document reflects that used in the specifications from which terms are taken, in
particular the TETRA air interface specification ETSI EN 300 392-2 [1] and the 3GPP stage 2 and stage 3
specifications. This may lead to some difference in terminology between differen
