17、6.1.0 (2004-12) 5 Release 6 1 Scope The present document defines the stage one description of the Transport Protocol, CAT_TP, for CAT applications based on TS 102 223 1. The Bearer Independent Protocol as defined in TS 102 223 1 allows a CAT application on the UICC to establish a data channel with t
18、he terminal, and through the terminal either to a remote server in the network or to a remote device in the Personal Area Network (PAN). The Bearer Independent Protocol obviously inherits the properties of the bearer and the network protocols it uses and may stand on top of unreliable transport prot
19、ocols (such as UDP). The present document contains the core requirements for the CAT_TP between the card and a remote entity to ensure acknowledgement, segmentation/fragmentation, retransmission of messages, etc. The transport mechanisms specified are independent of applications and used bearers. Ev
20、en if the current definition of the CAT_TP protocol is focused on the Bearer Independent Protocol, it does not prevent the CAT_TP to be used over future UICC-TE communication protocol. 2 References The following documents contain provisions which, through reference in this text, constitute provision
21、s of the present document. References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

24、rted by the terminal and the network NOTE: As defined in TS 102 223 1. CAT_TP client: entity which initiates a CAT_TP link to the CAT_TP server, and applies during the connection phase only NOTE: It could be on the UICC or on the remote entity. CAT_TP server: entity which receives a CAT_TP link esta
25、blishment request from a CAT_TP client, and applies during the connection phase only NOTE: It could be on the UICC or on the remote entity. ETSI ETSI TS 102 124 V6.1.0 (2004-12) 6 Release 6 CAT_TP entity: entity able to open a CAT_TP link, exchange CAT_TP PDUs (see annex B) and close a CAT_TP link C
26、AT_TP Service Data Unit: in the reference model for OSI, amount of information whose identity is preserved when transferred between peer (N + 1)-layer entities and which is not interpreted by the supporting (N)-layer entities NOTE: Here (N)-layer is the CAT_TP layer. Physical link: is composed of th
27、e Bearer Independent Protocol channel between the UICC and the TE and a bearer specific link between the TE and the remote entity CAT_TP link: logical link between CAT_TP entities over which CAT_TP PDUs are exchanged 3.2 Abbreviations For the purposes of the present document, the following abbreviat

29、DU Service Data Unit (in the context of the present document, a CAT_TP SDU) TE Terminal Equipment UICC Universal Integrated Circuit Card WAN Wide Area Network 4 Description The Bearer Independent Protocol, as defined in TS 102 223 1, provides to the UICC a standardized way to use TE bearers to commu
30、nicate with remote entities in a WAN or in a PAN. The UICC and the TE exchange data together. The TE and the server exchange data together. According to figure 1, the physical link is composed of the BIP and the Bearer Specific Protocol between the TE and the remote entity. Several CAT_TP links can
31、share a physical link. UICC TE remote entity BIP Bearer Specific CAT_TP CAT_TP entity CAT_TP entity Figure 1: Data exchanges overview Without the CAT_TP, the CAT application is unable to know if the remote entity has received the data sent. Moreover, without CAT_TP, the remote entity possibly receiv
32、es data without transport information such as the emitter identity, packet numbering or transmission status, etc. The CAT_TP aims to provide the possibly missing transport functionalities. ETSI ETSI TS 102 124 V6.1.0 (2004-12) 7 Release 6 5 Requirements 5.1 Transport requirements 5.1.1 General requi
33、rements The CAT_TP shall allow enhancement without compromising backward compatibility. The CAT_TP flexibility shall be considered for the best efficiency for applications and bearers. (e.g. to gain bandwidth, performances, by activating/deactivating some of the CAT_TP features). Deployed protocols
34、shall be considered as a possible stage 2 solution. A negotiation mechanism, between CAT_TP entities, shall be available for all CAT_TP negotiable features (e.g. receive/transmit buffers, acknowledgement mechanisms) in order to achieve CAT_TP interoperability. Sets of valid combinations of CAT_TP ne
35、gotiable features shall be defined. There shall be a limited number of sets. The CAT_TP shall provide full-duplex communication. 5.1.2 Physical link requirements This clause is left FFS. 5.1.3 CAT_TP link requirements The CAT_TP shall allow a connection oriented mode. A CAT_TP connectionless mode ne
36、ed is FFS. 5.1.4 CAT_TP connection mechanisms requirements 5.1.4.1 Definition The CAT_TP connection oriented mode provides functions to open and to close CAT_TP links. The connection set-up is the request from CAT_TP client to CAT_TP server to establish a CAT_TP link with CAT_TP specific parameters,
37、 and optional parameters for physical link establishment. This mechanism includes the closing of CAT_TP link. The connection set up could be achieved by the UICC or by the remote entity. 5.1.4.2 Functional requirements The connection set-up shall be done with specific PDUs. After the issuance of the
38、 link establishment request, the CAT_TP client shall wait for a link establishment response in a finite time. Upon the connection set-up, an error handling mechanism shall be available on the CAT_TP client side. Several connection set-ups shall be able to be performed on the same physical link. This
39、 ends up with several CAT_TP links established at the same time on the same physical link. During the CAT_TP connection set up, it shall be possible to choose between using already open physical links or opening a new one depending of the optionally given physical link parameters. The CAT_TP client
40、shall negotiate with the CAT_TP server the maximum PDU size and the maximum SDU size. At any moment, the CAT_TP client or CAT_TP server shall be able to close a CAT_TP connection. ETSI ETSI TS 102 124 V6.1.0 (2004-12) 8 Release 6 5.1.5 Segmentation mechanism requirements 5.1.5.1 Definition This mech
41、anism is the split of a SDU into several PDUs. 5.1.5.2 Purpose In case a SDU is larger than the maximum PDUs size negotiated during the connection step (emission and reception), a segmentation and re-assembly mechanisms shall be used. 5.1.5.3 Functional requirements Both CAT_TP entities shall suppor
42、t this segmentation and re-assembly requirements. There shall be an available mechanism to handle several out of sequence PDUs belonging to one SDU. There shall be an available mechanism to handle several PDUs from different SDUs. 5.1.6 Reliable message exchange requirements 5.1.6.1 Definition Ackno
43、wledgement and retransmission allow reliable message exchange. The acknowledgement allows the CAT_TP receiving entity to indicate to the CAT_TP sending entity it has received the previous data with or without errors. In case of bad transmission, retransmission applies. 5.1.6.2 Purpose This mechanism
44、 allows CAT_TP entities to exchange data in a reliable manner. 5.1.6.3 Functional requirements The acknowledgement and the retransmission shall be possible, if requested by CAT_TP entities: - at the SDU level; - at the PDU level; - for several PDUs. A mechanism shall be available to handle lost or c
45、orrupted (i.e. corrupted header) PDUs and SDUs (data or control messages). Checksum mechanism is not considered to be necessary since data integrity is considered to be handled by physical link. Flow control shall be considered in the CAT_TP. 5.2 Application requirements 5.2.1 Upper layer identifica
46、tion mechanism requirements 5.2.1.1 Purpose This feature is needed to inform the receiving entity of the data format. ETSI ETSI TS 102 124 V6.1.0 (2004-12) 9 Release 6 5.2.1.2 Functional requirements There shall be a mechanism to identify an upper layer, if any. For example, it shall be able to iden
47、tify the security layer as defined in TS 102 225 2. 5.2.2 CAT_TP entities identification mechanism requirements 5.2.2.1 Purpose This feature allows CAT_TP entities to uniquely identify each other. 5.2.2.2 Functional requirements There shall be a mechanism to uniquely identify a CAT_TP link establish
48、ed between two CAT_TP entities. There shall be a mechanism to uniquely identify the sending CAT-TP entity.
