Patent ID: 8818357

Claim:
A method for the diagnostic testing of a mobile telephone terminal including UICC card containing a stored test application and a contactless communication module which can exchange data with a contactless unit by retromodulation of a signal transmitted by the unit, comprising a test operation whereby the unit performs the steps: ( 101 ) transmitting an initialization request having a predetermined format, ( 102 ) detecting a response transmitted by the mobile telephone terminal, or an absence of response by the mobile telephone terminal, when the unit detects a response transmitted by the mobile telephone terminal; ( 201 ) emitting a test application selection request; ( 202 , 204 ) detecting a response indicating application selection confirmation or failure, transmitted by the mobile telephone terminal; ( 203 , 206 ) determining the operating state of the UICC card or of the terminal as a function of the response detected, ( 301 ) transmitting a query command to the UICC card's directory querying a list of applications present on the UICC card, ( 302 ) determining whether a given application is present in the UICC card by looking for the application in the list of applications, ( 304 ) deducing an operating state of the application, said deducing being based on the presence or absence of the application in the list of applications; and ( 104 ) when the unit does not detect a response, then the unit deduces a malfunction of the terminal.
