29、d Transport. The following figure shows the transport protocol stacks over M1. GTP-U UDP IPv6 (RFC 2460) and/or IPv4 (RFC 791) Data link layer Physical layer Figure 5.1-1: Transport network layer for MBMS data streams over M1 The GTP-U (TS 29.281 2) protocol over UDP over IP shall be supported as th

30、e transport for MBMS data streams on the M1 interface. The data link layer is as specified in clause 4. On IP multicast mode, the transport bearer is identified by the GTP-U TEID (TS 29.281 2) and the IP multicast address (source TEID, IP address of multicast source, IP multicast address). 5.2 GTP-U

31、 The GTP-U (TS 29.281 2) protocol shall be used over the M1 interface toward the EPC. ETSI ETSI TS 136 445 V14.0.0 (2017-04)73GPP TS 36.445 version 14.0.0 Release 145.3 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. eNB

32、and EPC shall support fragmentation and assembly of GTP packets at the IP layer. The eNB and EPC shall support IPv6 (IETF RFC 2460 5) and/or IPv4 (IETF RFC 791 6). IP multicast (IETF RFC 3376 7, IETF RFC3810 8) shall be supported for point-to-multipoint delivery of MBMS data streams for multi-cell t

33、ransmission. The packet processing function in the EPC shall send MBMS data of a given MBMS bearer to the TNL IP multicast address associated to that particular MBMS bearer. 5.4 Diffserv code point marking IP Differentiated Services code point marking (IETF RFC 2474 4) shall be supported. The mappin

34、g between traffic categories and Diffserv code points shall be configurable by O&M based on QoS Class Identifier (QCI) Characteristics and other E-UTRAN traffic parameters. Traffic categories are implementation-specific and may be determined from the application parameters. ETSI ETSI TS 136 445 V14.
