A dialing method performed by a user terminal, the method comprising: • updating, in a first alternative, local preset number information, thereby arriving at updated local preset number information or, in a second alternative, updating a valid digit quantity, thereby arriving at an updated valid digit quantity by accessing, in the first and second alternatives, a wireless fidelity, Wi-Fi, system, • detecting at least one entering operation performed on a moment indication numeral on a clock dial, wherein the clock dial is displayed on a standby screen of the user terminal (step 501), • calculating each time the user terminal detects an entering operation, a time interval between the currently detected entering operation and a previous entering operation (step 502), • determining whether the time interval is less than a preset value (step 503), • determining, when the time interval is less than the preset value, a dialing numeral corresponding to the currently detected entering operation (step 504), • generating a dialing number according to the dialing numeral (step 505), • determining whether the dialing number is a valid number (step 506), wherein the determining whether the dialing number is the valid number is: ∘ in the first alternative, determining whether the dialing number matches a preset number as indicated by the updated local preset number information; if the dialing number matches the preset number, determining that the dialing number is the valid number, or, ∘ in the second alternative, determining whether a digit quantity of the dialing number is a valid digit quantity, wherein the valid digit quantity is a quantity of digits as indicated by the updated valid digit quantity, if the digit quantity of the dialing number is the valid digit quantity, determining that the dialing number is the valid number, • if the dialing number is the valid number, displaying a dialing icon on the standby screen (step 507), • performing a call by using the dialing number as a called number (step 508). • updating, in a first alternative, local preset number information, thereby arriving at updated local preset number information or, in a second alternative, updating a valid digit quantity, thereby arriving at an updated valid digit quantity by accessing, in the first and second alternatives, a wireless fidelity, Wi-Fi, system, • detecting at least one entering operation performed on a moment indication numeral on a clock dial, wherein the clock dial is displayed on a standby screen of the user terminal (step 501), • calculating each time the user terminal detects an entering operation, a time interval between the currently detected entering operation and a previous entering operation (step 502), • determining whether the time interval is less than a preset value (step 503), • determining, when the time interval is less than the preset value, a dialing numeral corresponding to the currently detected entering operation (step 504), • generating a dialing number according to the dialing numeral (step 505), • determining whether the dialing number is a valid number (step 506), wherein the determining whether the dialing number is the valid number is: ∘ in the first alternative, determining whether the dialing number matches a preset number as indicated by the updated local preset number information; if the dialing number matches the preset number, determining that the dialing number is the valid number, or, ∘ in the second alternative, determining whether a digit quantity of the dialing number is a valid digit quantity, wherein the valid digit quantity is a quantity of digits as indicated by the updated valid digit quantity, if the digit quantity of the dialing number is the valid digit quantity, determining that the dialing number is the valid number, ∘ in the first alternative, determining whether the dialing number matches a preset number as indicated by the updated local preset number information; if the dialing number matches the preset number, determining that the dialing number is the valid number, or, ∘ in the second alternative, determining whether a digit quantity of the dialing number is a valid digit quantity, wherein the valid digit quantity is a quantity of digits as indicated by the updated valid digit quantity, if the digit quantity of the dialing number is the valid digit quantity, determining that the dialing number is the valid number, • if the dialing number is the valid number, displaying a dialing icon on the standby screen (step 507), • performing a call by using the dialing number as a called number (step 508).
