A presentity improves presence service and includes a presentity account setup device adapted to cooperate with a presence server of a service provider (LOC_SP) of a local domain. The presentity account setup device includes presentity account definition means, responsive to an instruction input, to define a presentity account at the presence server of the service provider of the local domain by embedding a presentity identification in a domain under which the presentity is registered (ID_of_Presentity@EXT_SP.cc) into a user part of an identification for the local domain (ID_of_Presentity%40EXT_SP.cc@LOC_SP.cc). Further, a correspondingly adapted presence system network entity as well as a correspondingly adapted presence server enable a parking of presence information of a presentity outside its home presence system. Hence, roaming presentities and/or co-location of presentity identities are enabled.
