Apparatuses, methods, and systems are disclosed for target network slice information for target network slices. One method (900) includes receiving (902) a first message from a communication device including information indicating a request to register multiple network slices. The method (900) includes determining (904) target network slice information corresponding to multiple target network slices. The target network slice information includes information indicating network slices of the multiple network slices not supported in an area in which the communication device is located and a frequency specific configuration associated with the multiple target network slices. The method (900) includes transmitting (906) a second message to a radio network entity including the target network slice information and the associated frequency specific configuration.
