Introduction 3GPP is standardizing a
23、 set of mission critical services as applications working over 3GPP LTE systems. These services include speech PTT systems (MCPTT), data (MCData) and video (MCVideo) systems. Users have a need to interwork between TETRA and 3GPP MC systems for a number of reasons which can include: Communication bet
24、ween different user groups who receive service from the different types of system. Use of both systems by the same set of users to allow selection of optimum radio coverage and services in any situation. Migration from an existing TETRA system to a 3GPP MC system over a period of time, which may be
25、long. It is envisaged that an interworking function will be standardized as part of this work within ETSI TCCE to allow communication between TETRA and 3GPP MC systems. The present document provides considerations for realizing this interface. ETSI ETSI TR 103 565 V1.1.1 (2017-10) 61 Scope The prese
