Embodiment Construction

[0048] Analyzing the existing technology, when the user updates the phonebook entry under the GSM application through the terminal, the UICC can only identify and mark that the phonebook entry has been updated, but cannot specifically identify that the update has modified the original subject The information content of the phonebook entry still deletes the original subject, so it is impossible to judge whether the associated information content in the updated phonebook entry that the terminal cannot access under the GSM application still matches or is valid.

[0049] The solution of the present invention is described below.

[0050] The invention defines the EF of "mapped phonebook" PBC A certain reserved bit Bx (x can be an integer from 2 to 8, hereinafter referred to as Bx) in the first byte of the corresponding record of each phonebook entry in the file is "Consistency maintenance state of phonebook entry information content bit", the UICC uses Bx to mark whether the termi...
