Question: In UTRAN Iur interface RNSAP signalling, when using the Generic Traffic Category IE for uplink data traffic, what determines the generic traffic categories?
Option 1: Predefined values specified in standards for each application type
Option 2: Implementation-specific, potentially derived from application parameters by the sender
Option 3: Configurable by the end-user through UE settings
Option 4: Automatically negotiated between the RNC and the DRNS based on network load
Explanation: This is correct because, when the Generic Traffic Category IE is used, generic traffic categories are implementation-specific. This means that the determination of these categories can vary depending on how the system (e.g., the sender) chooses to interpret application parameters, rather than being standardized, user-configured, or dynamically negotiated based on network conditions.
