Abstract
A method for handling a proactive command in a mobile system with a subscriber identity card, executed by a micro-processing unit (MCU) of a Baseband chip, is provided. A response code is received from the subscriber identity card, wherein the response code indicates the mobile system to fetch the proactive command for a specific procedure. It is determined whether the mobile system is under a specific condition after receiving the response code. The response code is ignored until the specific condition is absent.
Claims20
A method for handling a proactive command in a mobile system with a subscriber identity card, executed by a micro-processing unit (MCU) of a Baseband chip, comprising:
- receiving a response code from the subscriber identity card, wherein the response code indicates the mobile system to fetch the proactive command for a specific procedure;
- determining whether the mobile system is under a specific condition after receiving the response code;
- and
- ignoring the response code until the specific condition is absent.
A method for handling a first proactive command and a second proactive command in a mobile system with a first subscriber identity card and a second subscriber identity card, comprising:
- receiving a first response code from the first subscriber identity card;
- issuing a first command in response to the first response code to the first subscriber identity card to obtain a first proactive command, so as to perform a first procedure according to the first proactive command;
- receiving a second response code from the second subscriber identity card;
- and
- not responding to the second response code when the first procedure is not completely preformed.
A system, comprising:
- a first subscriber identity card;
- and
- a processor receiving a first response code from the first subscriber identity card, the first response code indicating the processor to fetch a first proactive command for performing a first procedure, ignoring the first response code when a specific condition is present, and issuing a first command to the first subscriber identity card to obtain the first proactive command and performing the first procedure according to the first proactive command when the specific condition is absent.
