Method for adjusting ring volume through short message service

摘要

A method for adjusting ring volume through short message service includes steps of a communication device determining whether a volume adjusting condition is satisfied when there is a missed call; the communication device transmitting a first short message if the volume adjusting condition has been satisfied, wherein a first information element identifier (IEI) is set in the first short message and defined as a volume adjusting request in transfer protocol user data (TPUD) in advance; the communication device determining whether a second IEI is set in a second short message when receiving the second short message, wherein the second IEI is defined as a volume adjusting response in TPUD in advance; and the communication device selectively adjusting a ring volume thereof to maximum level if the second IEI is set in the second short message.

1. A method for adjusting ring volume through short message service comprising:
operating a first communication device to make a phone call to a second communication; the second communication device determining whether a volume adjusting condition is satisfied if the second communication device does not answer the phone call; the second communication device transmitting a first short message to the first communication device if the volume adjusting condition has been satisfied, wherein a first information element identifier (IEI) is set in the first short message and defined as a volume adjusting request in transfer protocol user data (TPUD) in advance; the first communication device generating a reply interface according to the first IEI set in the first short message, wherein the reply interface is used for selecting whether to adjust a ring volume of the second communication device to a maximum level; the first communication device transmitting a second short message to the second communication device if selecting to adjust the ring volume of the second communication device to the maximum level, wherein the second IEI is defined as a volume adjusting response in TPUD in advance; and the second communication device selectively adjusting the ring volume to the maximum level according to the second IEI set in the second short message.
