20、31 Scope The present document specifies the signalling transport related to NBAP signalling to be used across the Iub Interface. The Iub interface is a logical interface for the interconnection of Node B and Radio Network Controller (RNC) components of the UMTS Terrestrial Radio Access Network (UTRA
21、N) for the UMTS system. The radio network control signalling between these nodes is based on the Node B application part (NBAP). 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specifi
22、c (identified by date of publication, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific

NOTE: This does not preclude the single implementation and use of any other L2/L1 protocols (e.g. PPPMux/AAL5/ATM (IETF RFC 3153 17, IETF RFC 2364 18), PPP/AAL2/ATM, Ethernet, MPLS/ATM (IETF RFC 3031 19), etc.) fulfilling the UTRAN requirements towards the uppe

There may be multiple
36、 point-to-point links between an RNC and a Node B. As shown in figure 1, the standard allows operators to choose one out of two protocol suites for transporting the NBAP messages.

38、e protocols to be used to support NBAP signalling are SSCF-UNI (ITU-T Rec. Q.2130 2) on top of SSCOP (ITU-T Rec. Q.2110 3) and AAL Type 5 (ITU-T Rec. I.363.5 4). 5.3 Signalling bearer in case of IP Transport Option SCTP (IETF RFC 2960 7) over IP shall be supported as the transport for NBAP signallin
39、g bearer on Iub Interface. A RNC equipped with the SCTP stack option shall initiate the INIT procedure for establishing association. The data link layer is as specified in chapter 4.2. The checksum method specified in IETF RFC 3309 20 shall be used instead of the method specified in IETF RFC 2960 (7
40、). An IP UTRAN node shall support IPv6 (IETF RFC 2460 8). The support of IPv4 (IETF RFC 791 9) is optional. NOTE: This does not preclude single implementation and use of IPv4. IP dual stack is recommended for the potential transition period from IPv4 to IPv6 in the transport network. ETSI ETSI TS 12
