The data
30、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 The GTP-U (TS 29.281 2) protocol shall be used over the M1 inte

The UDP port number for GTP-U shall be as defined in TS 29.281 2. eNB and EPC shall support fragmentation and assembly of GTP packets
32、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 transmission. The packet processing function in the EPC shall sen

The mapping between traffic categories and Diffserv code points shall be c
34、onfigurable 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 V13.0.0 (2016-01)83GPP TS 36.445 version 13.0.0 Release 13Annex A (i
