WIRELESS TELECOMMUNICATION TERMINAL AND ITS METHOD FOR AVOIDING ENDLESS CALL FAILURE BY ANALYZING CAUSE OF CALL FAILURE

摘要

1. TECHNICAL FIELD OF THE INVENTION;The present invention relates to a wireless communication terminal and a method having a call connection failure prevention function according to the cause of the call connection failure.;2. The technical problem to be solved by the invention;The present invention analyzes the cause as the continuous call connection failure occurs, and if the call connection fails continuously for an abnormal reason in the terminal, by forcibly transitioning the state of the work task associated with it to a state capable of normal operation, the wireless communication terminal SUMMARY OF THE INVENTION An object of the present invention is to provide a wireless communication terminal and a method for preventing a call connection failure according to a cause of a call connection failure, so that a call connection request operation can be performed without powering off, thereby improving user convenience.;3. Summary of Solution to Invention;The present invention provides a method for preventing call connection failure according to a cause of call connection failure in a wireless communication terminal, comprising: a call connection request step of requesting a call connection upon receiving a call connection request signal; Call connection failure checking step of confirming a call connection failure; A recording step of recording the error code in the error code list; A checking step of analyzing the error code list and confirming that the number of occurrences of the same error code exceeds a preset limit number; And a normalizing step of transitioning a work task that has generated the same error code to a normal state.;4. Important uses of the invention;The present invention is used in a wireless communication terminal.;Consecutive call failure, cause of call failure, forced state transition, wireless communication terminal
