## Abstract

The present application discloses a method for displaying contact information, a method of handling a lost call, and an electronic apparatus using the same method of displaying contact information. The method of displaying contact information is applicable to an electronic apparatus. The method of displaying contact information would include at least but not limited to detecting inputted number in a dialer; displaying a contact in response to the inputted number; and displaying at least one of one or more indicators corresponding to the contact, wherein the indicator indicates a voice call availability corresponding to the contact.

## Claims

### Claim 1

A method of handling a lost call, applicable to a first electronic apparatus, comprising:
only if a call between the first electronic apparatus and a second electronic apparatus is finished, determining, by the first electronic apparatus, whether the call is finished by being hung up;
in response to determining the call is not finished by being hung up, determining, by the first electronic apparatus, whether the finished call was originally established by the first electronic apparatus; and
in response to determining the finished call was originally established by the first electronic apparatus, generating, by the first electronic apparatus, a first notification for suggesting establishing another call with the second electronic apparatus by the first electronic apparatus; and
in response to determining the finished call was not originally established by the first electronic apparatus, generating, by the first electronic apparatus, a second notification for suggesting waiting for the second electronic apparatus to establish the another call, wherein the first and second notifications are configured for preventing the first electronic apparatus and the second electronic apparatus from simultaneously calling each other.

### Claim 2 (depends on 1)

The method as claimed in claim 1, wherein generating the first notification for suggesting establishing another call with the second electronic apparatus comprising:
displaying a button for establishing the other call with the second electronic apparatus; and
the method further comprising:
determining whether the button is activated; and
after the button is activated, establishing the other call with the second electronic apparatus.

### Claim 3 (depends on 1)

The method as claimed in claim 1, wherein before generating the second notification in the first electronic apparatus for suggesting waiting for the second electronic apparatus to establish the other call, further comprising:
detecting whether the first electronic apparatus initiating the other call with the second electronic apparatus;
in response to detecting the first electronic apparatus initiating the other call with the second electronic apparatus, hanging up the other call.

### Claim 4

A mobile electronic apparatus, comprising:
a storage unit, storing a plurality of program codes;
a display unit; and
a processing unit coupled to the storage unit and the display unit, and configured for accessing the program codes to execute the following steps:
only if a call between the first electronic apparatus and a second electronic apparatus is finished, determining, by the first electronic apparatus, whether the call is finished by being hung up;
in response to determining the call is not finished by being hung up, determining, by the first electronic apparatus, whether the finished call was originally established by the first electronic apparatus; and
in response to determining the finished call was originally established by the first electronic apparatus, generating, by the first electronic apparatus, a first notification for suggesting establishing another call with the second electronic apparatus by the first electronic apparatus and controlling the display unit to display the first notification; and
in response to determining the finished call was not originally established by the first electronic apparatus, generating, by the first electronic apparatus, a second notification for suggesting waiting for the second electronic apparatus to establish the another call and controlling the display unit to display the second notification, wherein the first and second notifications are configured for preventing the first electronic apparatus and the second electronic apparatus from simultaneously calling each other.

### Claim 5 (depends on 4)

The mobile electronic apparatus as claimed in claim 4, wherein generating the first notification for suggesting establishing another call with the second electronic apparatus comprising:
displaying a button for establishing the other call with the second electronic apparatus; and
the method further comprising:
determining whether the button is activated; and
after the button is activated, establishing the other call with the second electronic apparatus.

### Claim 6 (depends on 4)

The mobile electronic apparatus as claimed in claim 4, wherein before generating the second notification in the first electronic apparatus for suggesting waiting for the second electronic apparatus to establish the other call, further comprising:
detecting whether the first electronic apparatus initiating the other call with the second electronic apparatus;
in response to detecting the first electronic apparatus initiating the other call with the second electronic apparatus, hanging up the other call.

### Claim 7

A non-transitory computer readable medium for recording a program configured to be loaded by a first electronic apparatus to execute steps of:
only if a call between the first electronic apparatus and a second electronic apparatus is finished, determining, by the first electronic apparatus, whether the call is finished by being hung up;
in response to determining the call is not finished by being hung up, determining, by the first electronic apparatus, whether the finished call was originally established by the first electronic apparatus; and
in response to determining the finished call was originally established by the first electronic apparatus, generating, by the first electronic apparatus, a first notification for suggesting establishing another call with the second electronic apparatus by the first electronic apparatus; and
in response to determining the finished call was not originally established by the first electronic apparatus, generating, by the first electronic apparatus, a second notification for suggesting waiting for the second electronic apparatus to establish the another call, wherein the first and second notifications are configured for preventing the first electronic apparatus and the second electronic apparatus from simultaneously calling each other.

### Claim 8 (depends on 7)

The non-transitory computer-readable medium as claimed in claim 7, wherein generating the first notification for suggesting establishing another call with the second electronic apparatus comprising:
displaying a button for establishing the other call with the second electronic apparatus;
determining whether the button is activated; and
after the button is activated, establishing the other call with the second electronic apparatus.

### Claim 9 (depends on 7)

The non-transitory computer-readable medium as claimed in claim 7, wherein before generating the second notification in the first electronic apparatus for suggesting waiting for the second electronic apparatus to establish the other call, further comprising:
detecting whether the first electronic apparatus initiating the other call with the second electronic apparatus;
in response to detecting the first electronic apparatus initiating the other call with the second electronic apparatus, hanging up the other call.
