Abstract
The present invention relates to a method and system for restoring a transferred mobile service by a mobile transfer service. To this end, the present invention provides a method for restoring a mobile service that releases a mobile transfer state of a first mobile terminal when it is confirmed that a state where the power strength of a common pilot channel received from a second mobile terminal is a previously set threshold value or less is maintained for a previously set threshold time or more. In addition, the present invention provides a method for restoring mobile service that releases a mobile transfer state of the first mobile terminal when it is confirmed that the frequency of a period that is the power threshold value or less of the common pilot channel received from the second mobile terminal exceeds the previously set threshold frequency within the previously set time unit. Further, the present invention provides a method for restoring mobile service that releases and restores the mobile transfer state of the first mobile terminal when the first mobile terminal is located in a service possible area and the second mobile terminal is located in a shadow area. According to the present invention, a situation where mobile communication service subscribers do not receive important mobile communication service can be prevented from occurring, which is caused by not performing a procedure of restoring the transferred mobile terminal.
