Question: In a cellular network supporting Machine Type Communication (MTC), what determines the activation of some MTC functions in User Equipment (UE)?
Option 1: Roaming agreements between operators
Option 2: Indicators sent by the UE to the network and/or subscriber data
Option 3: Network configuration (both visited and home networks)
Option 4: Type of subscription plan associated with the UE
Explanation: MTC functions are triggered by specific controls. Subscriber data, stored on the network side, defines services and features a user/device is entitled to. Indicators from the UE to the network can initiate/modify MTC functions, adapting to the UE's needs/state. While network configuration enables MTC functionality and roaming agreements affect feature availability when roaming, they don't directly determine activation of specific MTC functions in the UE. The subscription plan influences the broader service package but isn't directly linked to technical activation of MTC functions within network and UE interaction.
