TIA-102.BACA-B-3 specifies requirements for this addendum that adds a normative annex to TIA-102.BACA-B to enable interworking for the services defined in phase 1 of the ATIS WTSC/TIA TR-8 Joint Land Mobile Radio to Long-Term-Evolution (JLMRLTE) architectural study of interworking between P25 LMR and 3GPP mission critical services.   In other words, it will describe how a 3GPP Inter Working Function (IWF) may act as a Home or Serving RFSS for the phase 1 interworking services of Group Registration / De-registration, Group Call (non-emergency and emergency), Announcement Group Call, and Broadcast Group Call.

TIA-102.BACA-B-3 was formulated under the cognizance of the TIA TR-8 Mobile and Personal Private Radio Standards, TR-8.19 Wireline Systems Interfaces subcommittee.
