Abstract
Embodiments of the present invention provide methods for providing a non-registering endpoint with non-registration services (such as the ability to make a call) in an IMS network without requiring the non-registering endpoint to register. A request for a non-registration service is received and processed by an entity in the IMS network that is configured to handle such requests. The entity requires information about the non-registering endpoint itself before it can process the request. Since the non-registering endpoint is part of the network, a Home Subscriber Server (HSS) knows some information about the non-registering endpoint, but can only provide this information to the entity if the non-registering endpoint is registered or being registered by the entity. Consequently, in embodiments, the entity makes it look like the non-registering endpoint is registering, in order for the entity to obtain the information from the HSS.
