Cellular phone, cellular phone failure judgment method and failure judgment apparatus

A cellular phone comprising:

• a memory part which stores normal communication history information when communication is performed normally, origination and receive failure history information when origination and receive are not performed normally, and communication interruption history information when communication is interrupted;
• an interface part which outputs each history information stored in said memory part to an external terminal connected to said interface part.

A method of cellular phone failure judgment comprising the steps of:

• connecting a cellular phone to an external terminal, said cellular phone comprising a memory part which stores, as communication history information, notification information sent from a base station and information indicating radio status when communication is performed normally, a reason why communication is not performed normally when communication is not performed normally, and notification information sent from a base station and information indicating radio status when communication is not performed normally;
• and an interface part which outputs said communication history information to said external terminal;
• said external terminal reading said communication history information stored in said memory part of said cellular phone, and performing failure judgment for said cellular phone.

A method of cellular phone failure judgment comprising the steps of:

• a cellular phone storing normal communication history information when communication is performed normally, origination and receive failure history information when origination and receive are not performed normally, and communication interruption history information when communication is interrupted;
• a failure judgment apparatus reading said normal communication history information, said origination and receive failure history information and said communication interruption history information;
• said failure judgment apparatus performing failure judgment for receive synchronization and receive sensitivity in a receive system and for send power in a send system.

A failure judgment apparatus comprising:

• a part which connects to a cellular phone storing normal communication history information when communication is performed normally, origination and receive failure history information when origination and receive are not performed normally, and communication interruption history information when communication is interrupted;
• a part which reads said normal communication history information, said origination and receive failure history information and said communication interruption history information;
• a part which performs failure judgment for receive synchronization and receive sensitivity in a receive system and for send power in a send system.

A computer readable medium storing program code for causing a computer to perform failure judgment for a cellular phone, wherein said computer connects to said cellular phone which stores normal communication history information when communication is performed normally, origination and receive failure history information when origination and receive are not performed normally, and communication interruption history information when communication is interrupted, said computer readable medium comprising:

• program code means for reading said normal communication history information, said origination and receive failure history information and said communication interruption history information;
• program code means for performing failure judgment for receive synchronization and receive sensitivity in a receive system and for send power in a send system.
