There are provided measures for enabling/realizing network slice discovery in an overlapping network slice deployment. Such measures exemplarily comprise registration of a network slice mapping between a network slice identification information and a network slice type information for at least one service-related network slice in an overlapping network slice deployment, said network slice type information being indicative of a service-related capability of the at least one service-related network slice, and identification of a service-related network slice in the overlapping network slice deployment on the basis of the registered network slice mapping and a service.
