Abstract

A method for performing a call is disclosed. When a user attempts a call at a certain phone number of another party but ends in a call unavailable state, the user can automatically make a call at another contact of the another party'"'"'s contacts stored in the phone book of the another party by using call state information provided from a mobile communication network system. The method comprises making a first call at first contact of another party desired for a call connection, receiving call state information with respect to a call unavailable state of the first call if the first call ends in the call unavailable state, analyzing the received call state information and searching a phone book of the another party, and making a second call at second contact read from the phone book of the another party based on the analysis and search.

Claims

1. A method for performing a call by a mobile communication terminal comprising:

performing a call at one of contacts of another party desired for a call connection;

automatically performing a follow-up call at another contact of the another party if the call connection is failed.

2. The method according to claim 1, wherein the contact at which to perform the follow-up call is automatically searched from list of contacts in the another party'"'"'s phone book.

3. The method according to claim 1, wherein the contact at which to perform the follow-up call is set with call priority next to the contact at which to perform the call.

4. The method according to claim 1, wherein the contact at which to perform the follow-up call is a kind of phone number or a message contact.

5. The method according to claim 4, wherein the message contact comprises at least one of an email address and a phone number for sending message.

6. The method according to claim 1, further comprising receiving call state information from a mobile communication network system if the call connection is failed.

7. The method according to claim 6, wherein the call state information includes information with respect to cause of a call connection failure

8. The method according to claim 6, wherein the call state information is a type of certain digital code.

9. The method according to claim 6, wherein the call state information comprises information about a busy state, a power-OFF, or a no-response state.

10. The method according to claim 1, further comprising:

providing a message composing window if the contact at which to perform the follow-up call is a kind of a message contact; and

performing a follow-up call by transmitting a message composed by a user on the message composing window.

11. A method for performing a call by a mobile communication terminal comprising:

(a) making a first call at first contact of another party desired for a call connection;

(b) receiving call state information with respect to a call unavailable state of the first call if the first call ends in the call unavailable state;

(c) analyzing the received call state information and searching a phone book of the another party; and

(d) making a second call at second contact read from the phone book of the another party based on the analysis and search.

12. The method according to claim 11, wherein the phone book of the another party comprises at least one or more phone numbers of the another party.

13. The method according to claim 12, wherein the phone book of the another party comprises an e-mail address or a facsimile number besides the phone number of the another party.

14. The method according to claim 12, wherein call priority can be set for at least one or more phone numbers, the e-mail address and the facsimile number inputted in the phone book of the another party, which can be then inputted.

15. The method according to claim 11, wherein, in the step (a), the first contact is a certain phone number set with first call priority in the phone book of the another party.

16. The method according to claim 11, wherein the step (c) comprises:

displaying the analyzed call state information; and

checking whether other contacts than the first contact has been registered in the phone book of the another party.

17. The method according to claim 11, wherein the step (d) comprises:

checking whether call priority has been set in the phone book of the another party;

if call priority has been set, reading second contact set with second call priority;

if call priority has not been set, displaying the phone book of the another party and selecting and reading by a user the second contact at which a call is to be made to the another party from the phone book of the another party; and

making a second call at the read second contact.

18. A mobile communication terminal for performing a call comprising:

a memory unit for storing a phone book including at least one or more contacts with respect to a particular party;

a controller for analyzing call state information transmitted by a mobile communication network system, searching contacts from a phone book of another party stored in the memory unit to perform a successive call to the another party, reading the corresponding contact, and performing the successive call; and

a RF unit for transmitting a signal of a call to the another party and receiving a call state information transmitted by a mobile communication network system.

19. The terminal according to claim 18, wherein the memory unit stores the phone book including contacts such as at least one or more phone numbers and e-mail addresses for which call priority has been set.

20. The terminal according to claim 18, wherein when a certain call to the another party is in a call unavailable state, for a successive call, the controller searches the memory unit to check whether there are other contacts in the phone book of the another party stored in the memory unit, checks whether call priority has been set for the other contacts, and reads the contact set with highest call priority from the memory unit.

21. The terminal according to claim 20, wherein the controller determines whether a kind of the read contact is a phone number or a message contact.

22. The terminal according to claim 18, further comprising;

a display unit for displaying the analyzed call state information and the phone book stored in the memory unit and providing an message composing window under the control of the controller.
