Abstract

The invention relates to a mobile terminal, and in particular to a method for after service of a mobile terminal which is adapted to optimize the performance of the mobile terminal. The method comprises the steps of: self-diagnosing, judging if the terminal malfunctions and connecting with the A/S center in the mobile terminal; requesting from the A/S center state information for indicating the operated condition to the mobile terminal; transmitting from the mobile terminal the stated information thereof according to the request; analyzing the transmitted state information and transmitting control information; and correcting the operated condition of the mobile terminal according to the transmitted control information. According to the method for after service of the mobile terminal, the inconvenience of the user to visit the A/C center can be reduced.

Claims

1. A method for after service of a mobile terminal is comprising the steps of:

self-diagnosing, judging if the terminal malfunctions and connecting with the A/S center in the mobile terminal;

requesting from the A/S center state information for indicating the operated condition to the mobile terminal;

transmitting from the mobile terminal the stated information thereof according to the request;

analyzing the transmitted state information and transmitting control information; and

correcting the operated condition of the mobile terminal according to the transmitted control information.

2. A method for after service of a mobile terminal according to

claim 1

, wherein the mobile terminal inspects by itself if the mobile terminal is malfunctioning and outputs an error message on a display in said step of self-diagnosing.

3. A method for after service of a mobile terminal according to

claim 2

, wherein if the mobile terminal is proved malfunctioning as a result of the self-diagnosing, the mobile terminal sets an A/S center and a call, and transmits state information thereof.

4. A method for after service of a mobile terminal according to

claim 1

, wherein the state and control information of the mobile terminal is transmitted by using an SMS or data communication service.

5. A method for after service of a mobile terminal according to

claim 1

, wherein the state information of the mobile terminal includes objective information and analogical information extracted from the objective information.

6. A method for after service of a mobile terminal according to

claim 5

, wherein the objective information is one selected from the group including temperature of the terminal, voltage, and received or output intensity variation information.

7. A method for after service of a mobile terminal according to

claim 5

, wherein the analogical information is one selected from the group including frame error rate, hand off state and carrier interference information.

8. A method for after service of a mobile terminal according to

claim 1

, wherein said step of correcting the operated condition of the mobile terminal is repeated until the operated condition of mobile terminal is optimized.

9. A method for after service of a mobile terminal according to

claim 1

, wherein upon correcting the operated condition thereof, the mobile terminal transmits information of a correction result to the A/S center.

10. A method for after service of a mobile terminal according to

claim 1

, wherein upon receiving the correction information, the A/S center analyzes the correction information to judge the state of the mobile terminal.

11. A method for after service of a mobile terminal according to

claim 1

, wherein the mobile terminal and the A/S center are connected via a base station, wherein the base station and the A/S center are wire connected by using a PSTN.

12. A method for after service of a mobile terminal according to

claim 11

, wherein the base station and A/S center are radio connected via another mobile terminal by using a cellular radio network.

13. A method for after service of a mobile terminal according to

claim 11

, wherein the base station and A/S center are radio connected via another mobile terminal by using a data communication network.

14. A method for after service of a mobile terminal in a system having the mobile terminal and an A/S center, said method comprising the steps of:

call setting between the mobile terminal and A/S center;

self-diagnosing, judging if the terminal malfunctions and connecting with the A/S center in the mobile terminal;

requesting from the A/S center state information for indicating the operated condition to the mobile terminal;

transmitting from the mobile terminal the stated information thereof according to the request;

analyzing the transmitted state information and transmitting control information; and

correcting the operated condition of the mobile terminal according to the transmitted control information.
