7 Other Iu Interface Specifications
25.4103GPPRelease 17TSUTRAN Iu interface: General aspects and principles
7.1 UTRAN Iu Interface: Layer 1 (3GPP TS 25.411)
TS 25.411 [4] specifies the range of physical layer technologies that may be used to support the Iu interface.
7.2 UTRAN Iu Interface: Signalling Transport (3GPP TS 25.412)
TS 25.412 [5] specifies the signalling bearers for the RANAP and transport network control plane protocols for both Iu-PS and Iu-CS.
7.3 UTRAN Iu Interface: RANAP Specification (3GPP TS 25.413)
TS 25.413 [6] specifies the RANAP protocol for radio network control plane signalling over the Iu interface.
7.4 UTRAN Iu Interface: Data Transport and Transport Signalling (3GPP TS 25.414)
TS 25.414 [7] specifies the transport bearers for the user plane of the Iu interface. It also specifies the protocol used to control these transport bearers.
7.5 UTRAN Iu Interface: CN-UTRAN User Plane Protocol (3GPP TS 25.415)
TS 25.415 [8] specifies the user plane frame handling protocol for the Iu interface.
7.6 UTRAN Iu Interface: Service Area Broadcast Protocol SABP (3GPP TS 25.419)
TS 25.419 [14] specifies the communication requirements over the Iu interface towards the BC domain.
7.7 Summary
The present document, 3GPP TS 25.410, specifies the general aspects and principles of the Iu interface as a whole.
The relationship between the other technical specifications that define the UTRAN Iu interface is shown in figure 7.1.
