41、ions based on ETSI TS 102 223 2. The present document contains the core functionalities for the CAT_TP between two CAT_TP entities hosting for instance on a UICC and on a remote entity. The CAT_TP described in the present document is based on RDP version 2 as specified in IETF RFC 908 4 and IETF RFC

42、 1151 5. The present document describes, according requirements defined in ETSI TS 102 124 1: The core functionalities of CAT_TP (data structures, state diagrams, protocol procedures, etc.). Usage of CAT_TP on top of the Bearer Independent Protocol (BIP). The following items are out of the scope of

43、the present document: The specific implementation of an API. Anything dealing with the security above CAT_TP. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
