Abstract
The present invention is aimed to provide a simplified mechanism to handle Public Service Identities identifying services in a network when a given Public Service Identity (PSI) belongs to a range of Public Service Identities defined as a so-called ~Wildcard PSI~ range. Therefore, the present invention provides a new method, a new central entity in the network, and enhanced Home Subscriber Server, serving entity, and routing entity, all co-operating to carry out different embodiments for the invention by handling an identifier of the .LAMBDA.Wildcard PSI' range, which includes the given Public Service Identity, the .LAMBDA.wildcard PSI' range being associated with a common service profile to be applied for services identified by those Public Service Identities belonging to the ~Wildcard PSI~ range.
