Question: What should a GTP-C entity do when providing load control information in a message for the first time or subsequently?
Option 1: Include only the changed subset of the load control information.
Option 2: Include the full set of load control information, but with different Load-Control-Sequence-Numbers for each instance.
Option 3: Always include the full set of load control information, i.e. all node level and APN Level applicable instances of the Load Control Information, with the same Load-Control-Sequence-Number for all instances.
Option 4: Include only non-critical optional parameters in the load control information.
Explanation: According to the specification, when providing load control information in a message for the first time or subsequently, the GTP-C entity shall always include the full set of load control information, i.e. all node level and APN Level applicable instances of the Load Control Information, even if only a subset of the load control information has changed. This ensures that the receiver has the most up-to-date and complete information for node selection.
