ETSI ETSI TS 125 460 V13.0.0 (2016-01)53GPP TS 25.460 version 13.0.0 Release 131 Scope The present document is an introduction to

22、the 3GPP TS 25.46x series of Technical Specifications that define the Iuant Interface for UMTS and E-UTRAN. The logical Iuant interface is a Node B/eNB internal interface between the implementation specific O - The Data Link Layer (Layer 2) for the Signalling Transport uses a specific class of the H

23、DLC standard as defined in ISO/IEC 13239 5; - The Application Layer (Layer 7) defines the data payload format and the required command set. This layer is called the “Iuant: Application Part“. This compact model for the control interface provides an efficient protocol stack suitable for implementatio

24、n on a single embedded micro-controller. 4.3 Iuant interface specification objectives The Iuant interface specifications shall facilitate the following: - Controlling the tilting of RET antennas remotely from the O - Indicating of TMA alarms and optionally controlling the gain of TMAs remotely from

25、the O - Interfacing a mix of RET antennas, TMAs and Node Bs from different vendors; - Providing RET or TMAs functionality in the UTRAN/E-UTRAN accompanied by an appropriate set of signalling commands and control parameters - Support of error and alarm handling. 4.4 Iuant interface characteristics Th

26、e Iuant interface has a protocol structure as shown below in figure 4.4.1. ETSI ETSI TS 125 460 V13.0.0 (2016-01)73GPP TS 25.460 version 13.0.0 Release 13O - An addressing scheme; - A master/slave relationship whereby the primary device controls the half duplex timing; - A message checksum scheme to

27、 protect from transmission errors; - A message sequence numbering scheme which protects layer 7 from: ETSI ETSI TS 125 460 V13.0.0 (2016-01)83GPP TS 25.460 version 13.0.0 Release 13- Duplicated messages; - Deleted messages; - Receiving messages in the wrong order. - A flow control mechanism protecti

28、ng each device from being overrun by messages. These functions provide layer 7 with a safe full-duplex connection between the primary device and any secondary device. This full duplex connection allows both the primary and secondary device to transmit layer 7 messages to the opposite device of the c

29、onnection, whenever they need to. Actual delivery time on layer 2 will depend on the layer 2 polling frequency, which is chosen by the primary device. 5.3 Application layer functions The list of functions on the Iuant interface is the following: - Control of RET antennas; - Application software and

30、configuration data download; - Alarm Reporting; - Operator specific data storage; - Control of Tower Mounted Amplifiers (TMAs). 5.3.1 Control of RET antennas A RET device provides means to adjust the electrical tilt of one or multiple antennas. The set of procedures to control RET antennas provides

31、means to control the electrical tilt of one or more RET antennas remotely. The procedures are defined in TS 25.466 7. 5.3.2 Application software and configuration data download The interface provides means for downloading new application software and configuration data to a secondary device. The sup

32、port of application software download to a secondary device is optional. If a secondary device supports application software download, it shall reset itself and start running the new application software automatically after the completed download. Further details on the software download procedure (

33、e.g. the different states of the secondary device and the supported elementary procedures in these states) are described in subclause 6.1 of TS 25.466 7. 5.3.3 Alarm reporting The secondary device reports every change in error status after subscription for alarm reporting by transmitting alarm messa

34、ges to the primary device. Alarm information can also be interrogated in the application layer. 5.3.4 Operator specific data storage The secondary device provides means for storage of operator specific data, e.g. inventory information. 5.3.5 Control of Tower Mounted Amplifiers (TMAs) The TMA device

35、provides means to indicate alarms and optionally to adjust the gain of TMAs. The set of procedures to control TMAs are defined in TS 25.466 7.

39、 25.460 version 13.0.0 Release 13Annex A (informative): OSI model overview Figure A.1: Relevant OSI model layers Figure A.1 shows the relevant OSI model layers and the communication paths between the primary and secondary device. The two important aspects of the OSI model are: - It defines a layered

40、 structure for the communication software; - It provides each layer with an apparent direct link to the same layer at the other device. However, in real life, the only actual message path between the two devices is through the physical connection between the two layer 1 entities. The layer 2 entitie

41、s appear to communicate directly. In actual fact, a message passed from the first device to the second device takes the following path: - Layer 2 at the first device passes the message down to Layer 1; - Layer 1 transmits the message across the physical connection (for instance a wire) to layer 1 at

42、 the second device; - Layer 1 at the second device passes the message up to Layer 2 at the second device. Likewise, layer 7 entities appear to communicate directly. In actual fact, a message passed from the first device to the second device takes the following path: - Layer 7 at the first device pas

43、ses the message down to Layer 2; - Layer 2 at the first device passes the message down to Layer 1; - Layer 1 transmits the message across the physical connection (for instance a wire) to layer 1 at the second device; - Layer 1 at the second device passes the message up to Layer 2 at the second devic

44、e; - Layer 2 at the second device passes the message up to Layer 7 at the second device. 7 Application 7 Application1 Physical2DataLink1 Physical2DataLinkActual message pathApparent message pathETSI ETSI TS 125 460 V13.0.0 (2016-01)113GPP TS 25.460 version 13.0.0 Release 13Annex B (informative): Cha
