Abstract: Devices, methods, apparatus and computer readable storage media for service management in a communication system are provided. The method comprises determining, at a first device, a set of candidate service providers for providing a service to a second device in place of a current service provider based on a mapping between the second device and a plurality of service providers having an ability to provide the service (310) and transmitting a message indicating the set of candidate service providers to the second device (320). In this way, an optimized function maintenance solution under service-based system architecture can be realized, thereby enhancing network stability and improving system performance.
