Specifically, a user inputs a calling number at a mobile phone terminal, and the mobile phone terminal receives an input operation of the user to acquire input information, that is, the calling number input by the user.

Step 402, searching a pre-set identifier which is the same as the communication identifier in a pre-stored identifier library.

The method comprises the steps that at least one preset identifier is stored in a pre-stored identifier library, and the preset identifier has the function of establishing communication connection in a state without a user identity identification card.

Step 403, if a preset identifier that is the same as the communication identifier is found in a pre-stored identifier library, determining that the communication identifier is a preset identifier.

Specifically, the terminal stores a commonly used emergency call number, i.e., a preset identifier in advance. After the user inputs the calling number, the terminal needs to determine whether the calling number input by the user is a pre-stored emergency calling number, and the determining method may be: the terminal searches the call number input by the user in a pre-stored identification library, and if the call number is the same as the call number input by the user, the call number input by the user can be determined to be an emergency call number.

For example, as shown in the pre-stored identifier library shown in table 1 below, if the call number input by the user is 110, the terminal searches 110 in the identifier library, and when 110 is found, it may be determined that the call number input by the user is an emergency call number.
