Question: In an MC (Mission Critical) service scenario, where topology hiding is not required, what determines if an MC service client affiliating with an MC service group (defined in a partner MC system for a single MC service) needs authorization from its primary MC system?
Option 1: The type of MC service the client is requesting (e.g., video, voice, data)
Option 2: The policy of the partner MC system where the MC service group is defined
Option 3: The capacity of the primary MC system to handle additional affiliations
Option 4: The geographical location of the MC service client
Explanation: According to the principles guiding mission critical communications, when an MC service client seeks to affiliate with a group defined in another (partner) MC system and topology hiding is not a concern, the primary factor influencing whether the client also needs authorization from its own (primary) MC system is determined by the policies of the partner MC system. This is because the partner system has the authority to decide who can join its defined groups, and its policies would extend to conditional requirements for additional authorizations from the affiliating client's primary system, ensuring secure and controlled group management.
