A method, a device, and a non-transitory storage medium are described in which an island tracking area code detection and remedial service is provided. A device may detect an island tracking area code cell based on a predicted optimal tracking area code. The device calculates scores for neighbor cells and their corresponding tracking area codes based on the distances of the neighbor cells from a target cell. The device may select the predicted optimal tracking area code based on these scores. The device may use the predicted optimal tracking area code as a basis to determine whether a tracking area code assigned to the target cell is an island tracking area code cell. The device may perform a remedial measure when an island tracking area code cell is detected.
