Abstract
The present invention is directed to a method of setting up a call from an originating user in an internet protocol (IP) multimedia subsystem (IMS) network. The originating user provides a signalling message containing an originating identifier of the user to a first node of the network. According to the method, a first node of the network receives the signalling message. The first node performs a verification on whether the originating identifier is associated with a wildcard identifier, wherein the wildcard identifier identifies a plurality of identifiers which are entitled to using a group service. If the originating identifier is associated with a wildcard identifier, the first node forwards the wildcard identifier and the originating identifier to a further node for setting up the call.
