Study on discreet listening and monitoring of mission critical services, Phase2
The present document studies solutions to satisfy the requirements for discreet monitoring of mission critical services. It identifies enhancements to be included in the technical specifications for MC Common functional architecture (3GPP TS 23.280 [2]), MCPTT (3GPP TS 23.379 [3]), MCVideo (3GPP TS 23.281 [4]), MCData (3GPP TS 23.282 [5]), MC Interworking with LMR (3GPP TS 23.283 [6]), and Mission Critical services over 5G System (3GPP TS 23.289 [7]). The requirements for this study are taken from the Stage 1 requirements in 3GPP TS 22.280 [8].
