Abstract
In mobile telecommunications, a generic busy response from a mobile equipment (ME), such as a smartphone or wearable device, to a proactive subscriber identity module (SIM) command can create ambiguity, potentially causing the SIM to initiate a retry logic. This may lead to redundant command traffic, increased power consumption, and potential race conditions. A signaling mechanism is described that includes a protocol enhancement where an ME can advertise its ability to internally store commands, for example, via a flag in a terminal profile command. When busy, the ME can queue the command and use a specific result code in a terminal response message, such as "command stored for later execution," to inform the SIM. This acknowledgement may allow the SIM to suspend its own retries, creating an arrangement that can reduce redundant traffic, conserve power, and improve system stability by shifting retry responsibility to the ME.
