IMPU – IMS Public User Identity

The Public User Identity is the means by which a subscriber of an IMS service is identified by other users of the service. For example, in VoLTE, the IMPU typically contains a representation of the subscriber’s telephone number. This could be in a SIP or Tel URI format.
