Abstract
The present invention relates to hiding a device identifier (IMEI) in a communication system. Identifying a device is done by indicating an international mobile equipment identity (IMEI) as an instance identifier of the device of a user. Generating a globally routable user agent uniform resource identifier (GRUU) for the user is done by encrypting the instance identifier so that the GRUU comprises an identity of the user and the encrypted instance identifier.
