ETSI ETSI TS 136 414 V14.0.0 (2017-04)53GPP TS 36.414 version 14.0.0 Release 141 Scope The present document specifies the standards for user data transport protocols and related signalling protocols to establish use
20、r plane transport bearers over the S1 interface. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or

27、ndpoint Identifier UDP User Datagram Protocol 4 Data Link Layer Any data link protocol that fulfils the requirements toward the upper layer may be used. 5 S1 Interface user plane protocol 5.1 General The transport layer for data streams over S1 is an IP based Transport. The following figure shows th
28、e transport protocol stacks over S1. GTP-U UDP IPv6 (RFC 2460) and/or IPv4 (RFC 791) Data link layer Physical layer Figure 6.1: Transport network layer for data streams over S1 The GTP-U (TS 29.281 2) protocol over UDP over IP shall be supported as the transport for data streams on the S1 interface.
29、 The data link layer is as specified in clause 4. The transport bearer is identified by the GTP-U TEID (TS 29.281 2) and the IP address (source TEID, destination TEID, source IP address, destination IP address). 5.2 GTP-U The GTP-U (TS 29.281 2) protocol shall be used over the S1 interface toward th
30、e EPC. 5.3 UDP/IP The path protocol used shall be UDP (IETF RFC 768 3). The UDP port number for GTP-U shall be as defined in TS 29.281 2. The eNB and the EPC shall support fragmentation and assembly of GTP packets at the IP layer. The eNB and the EPC shall support IPv6 (IETF RFC 2460 5) and/or IPv4
31、(IETF RFC 791 6). There may be one or several IP addresses in the eNB and in the EPC. The packet processing function in the EPC shall send downstream packets of a given E-RAB to the eNB IP address (received in S1-AP) associated to that particular E-RAB. The packet processing function in the eNB shal
32、l send upstream packets of a given E-RAB to the EPC IP address (received in S1-AP) associated to that particular E-RAB. The Transport Layer Address signalled in S1-AP messages is a bit string of ETSI ETSI TS 136 414 V14.0.0 (2017-04)73GPP TS 36.414 version 14.0.0 Release 14a) 32 bits in case of IPv4
33、 address according to IETF RFC 791 6; or b) 128 bits in case of IPv6 address according to IETF RFC 2460 5; or c) 160 bits if both IPv4 and IPv6 addresses are signalled, in which case the IPv4 address is contained in the first 32 bits. 5.4 Diffserv code point marking IP Differentiated Services code p
34、oint marking (IETF RFC 2474 4) shall be supported. The mapping between traffic categories and Diffserv code points shall be configurable by O&M based on QoS Class Identifier (QCI) Characteristics and others E-UTRAN traffic parameters. Traffic categories are implementation-specific and may be determi
35、ned from the application parameters. ETSI ETSI TS 136 414 V14.0.0 (2017-04)83GPP TS 36.414 version 14.0.0 Release 14Annex A (informative): Change History TSG # TSG Doc.
