Question: Upon receiving an SMS with semantically incorrect contents, which action does a Mobile Station (MS) take if the corresponding Short Message (SM) transfer is considered successfully transferred?
Option 1: The MS acknowledges the message and sends a confirmation to the network.
Option 2: The MS stores the message and notifies the user of potential errors.
Option 3: The MS attempts to correct the semantic error before processing.
Option 4: The MS ignores the message and enters an idle state, without sending any acknowledgement related to the error.
Explanation: When a Mobile Station receives an SMS with semantically incorrect contents but considers the SM transfer as successfully transferred, it will not engage with the erroneous content. Instead of attempting corrections or sending acknowledgments (which could imply successful receipt of meaningful content), the MS ignores the message to prevent potential processing issues. Entering an idle state after ignoring the message ensures the MS is ready for new, potentially valid transmissions without being tied up by the error. This approach aligns with efficient error handling in wireless communication protocols, prioritizing system readiness over erroneous data processing.
