1  ScopeWord‑p. 9
The present document studies use cases and identifies potential requirements for operation of the MCData service. MCData makes use of capabilities included in Group Communications System Enablers for LTE (GCSE_LTE), Proximity based Services (ProSe), and Isolated E-UTRAN Operation for Public Safety (IOPS) with additional requirements specific to the MCData Service. The MCData Service can be used for public safety applications and also for general commercial applications (e.g., utility companies and railways).
As far as possible, the MCData service will reuse applicable elements from the MCPTT service.
