It defines the provision of EPTS, the invocation of EPTS by an authorized user, the validation and authentication mechanisms used to prove the credentials of the EPTS user, the extensions required to the TIPHON generic simple call for EPTS, and the inter-domain carriage of EPTS calls. In addition the mechanisms for revocation of user authorization and of the EPTS service are defined.
