45、hall be used in the transport network user plane and the transport network control plane according to ITU-T Recommendation I.361 1. The structure of the cell header used in the UTRAN Iur interface is the cell header format and encoding at NNI (see Figure 3/I.361 1). ETSI ETSI TS 125 424 V13.0.0 (201
46、6-01)83GPP TS 25.424 version 13.0.0 Release 134.2 IP Transport Option A UTRAN Node supporting IP transport option shall support PPP protocol with HDLC framing (IETF RFC 1661 10, IETF RFC 1662 11). Note: This does not preclude the single implementation and use of any other data link layer protocols (
47、e.g. PPPMux/AAL5/ATM (IETF RFC 3153 20, IETF RFC 2364 21), PPP/AAL2/ATM, Ethernet, MPLS/ATM (IETF RFC 3031 22), etc.) fulfilling the UTRAN requirements toward the upper layers. An RNC using IP transport option having interfaces connected via slow bandwidth PPP links like E1/T1/J1 shall also support
48、IP Header Compression (IETF RFC 2507 12) and the PPP extensions ML/MC-PPP (IETF RFC 1990 13), (IETF RFC 2686 14). In this case, negotiation of header compression (IETF RFC 2507 12) over PPP shall be performed via IETF RFC 2509 15. 5 IurData Transport for Common Transport Channel Data Streams 5.1 Int
49、roduction This clause specifies the transport layers that support Common Channels (FACH, RACH, DSCH TDD, USCH TDD, HS-DSCH) Iur data streams. There are two options for the transport layer of the Common Channels data streams in Iur and Iub: 1) ATM based Transport (ATM transport option) 2) IP based Transport (IP transport option) The following figure shows the protocol stacks of the two options.
