Abstract
A method and a device for recovering a call service in a mobile communication system are provided. The method includes the following steps determining whether a second cell satisfies a condition for a terminal to perform an IP multimedia subsystem (IMS) registration when detecting that the terminal enters the second cell during a period in which the terminal waits for a next IMS registration due to an IMS registration failure in a first cell, initiating an initial IMS registration when determining that the second cell satisfies the condition, and recovering a call service of the terminal after the initial IMS registration is successful.
