0 Introduction p. 6
The work done for interconnection and migration did not fully address the needs for railways, additional work is required. Before starting additional normative stage 2 work on certain aspects, a study is initiated to identify gaps in existing mechanisms on interconnection and on migration and to develop solutions for those gaps. The technical report provides recommendations for solutions which are candidates for normative work.
1 Scope p. 7
The present document studies solutions to satisfy interconnection and migration needs for railways. It identifies enhancements to be included in the technical specifications for MCPTT (TS 23.379), MCVideo (TS 23.281), MCData (TS 23.282) and in the common functional architecture (TS 23.280) to support mission critical communications.
