Question: In E-UTRAN, when adapting handover and/or reselection configuration between cells for load balancing, how is a proposed change in handover trigger settings typically conveyed from the source cell to the target cell?
Option 1: By sending the absolute new value of the handover trigger setting along with a detailed justification for the change.
Option 2: Through a direct comparison of current and proposed cell reselection configurations.
Option 3: Via an update of the entire mobility configuration set, without highlighting specific changes.
Option 4: By expressing the difference (delta) between the current and new values of the handover trigger setting.
Explanation: In E-UTRAN, when adapting handover and/or reselection configurations for load balancing purposes, efficiency in communication between cells is crucial. Expressing proposed changes as a delta (difference) between current and new handover trigger values allows for concise communication, focusing on the actual change needed without requiring the full context of the current configuration to be sent. This approach enables quicker understanding and processing by the target cell, facilitating smoother adjustments in mobility settings.
