29、otocol 5.1 General The transport layer for data streams over X2 is an IP based Transport. The following figure shows the transport protocol stacks over X2. GTP-U UDP IPv6 (RFC 2460) and/or IPv4 (RFC 791) Data link layer Physical layer Figure 5.1: Transport network layer for data streams over X2 The

30、GTP-U (TS 29.281 2) protocol over UDP over IP shall be supported as the transport for data streams on the X2 interface. The data link layer is as specified in clause 4. There may be zero or one UL data stream and zero or one DL data stream per E-RAB at the X2 interface. - The DL data stream is used

31、for DL data forwarding from the source eNB to the target eNB. - The UL data stream is used for UL data forwarding from the source eNB to the target eNB. Each data stream is carried on a dedicated transport bearer. The identity of a transport bearer signalled in the RNL control plane consists of the

32、IP address and the TEID of the corresponding GTP tunnel, allocated by the target eNB (see TS 29.281 2). ETSI ETSI TS 136 424 V13.1.0 (2016-05)73GPP TS 36.424 version 13.1.0 Release 135.2 GTP-U The GTP-U (TS 29.281 2) protocol shall be used over the X2 interface between two eNBs. 5.3 UDP/IP The path

33、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 eNBs over the X2 interface shall support fragmentation and assembly of GTP packets at the IP layer. The eNB shall support IPv6 (IETF RFC 2460 5) and/or IPv4 (IETF RFC 791 6). There may

34、be one or several IP addresses in the both eNBs. The packet processing function in the source eNB shall send downstream packets of a given E-RAB to the target eNB IP address (received in X2AP) associated to the DL transport bearer of that particular E-RAB. The packet processing function in the sourc

35、e eNB shall send upstream packets of a given E-RAB to the target eNB IP address (received in X2AP) associated to the UL transport bearer of that particular E-RAB. The Transport Layer Address signalled in X2AP messages is a bit string of either a) 32 bits in case of IPv4 address according to IETF RFC

36、 791 6; or b) 128 bits in case of IPv6 address according to IETF RFC 2460 5. 5.4 Diffserv code point marking IP Differentiated Services code point marking (IETF RFC 2474 4) shall be supported. The mapping between traffic categories and Diffserv code points shall be configurable by O - The DL data st

38、 transport bearer of that particular E-RAB. The packet processing function in the SeNB shall send upstream packets of a given E-RAB to the MeNB IP address (received in X2AP) associated to the UL transport bearer of that particular E-RAB; - data forwarding may be performed by MeNB providing GTP-U TEI
