Question: In a Public Land Mobile Network (PLMN), when a User Equipment (UE) sends a call set-up message with insufficient Bearer Capability requirements, how does the network typically proceed?
Option 1: The network immediately notifies the UE of the missing information and terminates the call set-up process.
Option 2: The network attempts to insert the missing Bearer Capability information, if possible, and proceeds with the call set-up using the updated details.
Option 3: The network redirects the call set-up request to a different server for further processing without notifying the UE.
Option 4: The network always requires the UE to resend the call set-up message with complete Bearer Capability requirements.
Explanation: This is because, according to telecom principles for efficient call management, if the network can resolve minor issues like missing optional values by inserting the necessary information, it will do so to facilitate a successful call set-up, minimizing unnecessary back-and-forth signaling and enhancing user experience.
