<P>PROBLEM TO BE SOLVED: To enable the external device side to immediately confirm release of abnormality of a communication device in the case that the abnormality has been released after being reported to the external device. <P>SOLUTION: When managed devices (communication devices) 10 and 11 detect SC (abnormality), the managed devices transmit an SC call for reporting the SC to a management device 102 and set an SC call flag indicating the success of SC call transmission in response to reception of a transmission result from the management device 102, which shows normal termination of reception of the SC call. When the managed devices can recognize that the managed devices don't have SC in themselves or detect release of the SC, the managed devices check the SC call flag and transmit SC call release information to the management device 102 in response to recognizing that the SC call flag is set and reset the SC call flag in response to reception of a transmission result from the management device 102, which shows normal termination of reception of SC call release information. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
