16、24102-3:2013(E) Introduction This International Standard is part of a family of International Standards for communications access for land mobiles (CALM). An introduction to the whole set of International Standards is provided in ISO 21217. This part of ISO 24102 is part 3 of a multipart Internation
17、al Standard which determines the intelligent transport systems (ITS) station management service access points. The ITS station management entity provides functionality related to the management of communication protocol layers and the security entity presented in the ITS station reference architectu
18、re specified in ISO 21217 and presented in Figure 1, and in line with the general ITS architecture specified in ISO 21217. Communications Access Networking sent via the MI-SAP to the ITS-S access layer MI-REQUEST command issued by the ITS-S access layer and sent to the ITS-S management entity via th
19、e MI-SAP MI-SET command issued by the ITS-S management entity in order to set the value of one or several CI parameters; sent via the MI-SAP to the ITS-S access layer MN-COMMAND command issued by the ITS-S management entity and sent to the ITS-S networking and transport layer via the MN-SAP MN-REQUE

23、ommand issued by the ITS-S networking and transport layer and sent to the ITS-S security entity via the SN-SAP2 ISO 2013 All rights reserved ISO 24102-3:2013(E) 5 Requirements The ITS station management includes functionality specified in the various parts of this International Standard: 1) General
24、management functionality specified in ISO 24102-1. 2) The functionality of remote ITS station management specified in ISO 24102-2. 3) The functionality of management/security service access points specified this part of ISO 24102. 4) The functionality of ITS station-internal management communication
25、s specified in ISO 24102-4. 5) The functionality of the “Fast Service Advertisement Protocol” (FSAP) specified in ISO 24102-5. The functionality of the service access points MI-SAP, MN-SAP, MF-SAP, SI-SAP, SN-SAP, SF-SAP, MS-SA P, shall be as specified in this part of ISO 24102. NOTE 1 SAPs can be n
26、on-exposed interfaces. Thus, service primitives of SAPs are not subject to conformance tests. NOTE 2 The MA-interface and SA-interface presented in Figure 1 are not specified in this part of ISO 24102, although these are recognized as part of the ITS station reference architecture specified in ISO 2
27、1217. All interfaces towards the ITS-S applications are considered to be APIs rather than SAPs. Means to secure the access to management functionality need to be specified within the global context of CALM security. Details are outside the scope of this part of ISO 24102. Detailed mandatory requirem
28、ents are specified in the following clauses of this part of ISO 24102: Clause 6 specifies the MI-SAP. Clause 7 specifies the MN-SAP. Clause 8 specifies the MF-SAP. Clause 9 specifies the SI-SAP. Clause 10 specifies the SN-SAP. Clause 11 specifies the SF-SAP. Clause 12 specifies the MS-SAP. Annexes p
29、rovide further mandatory requirements. 6 MI-SAP 6.1 General Basically, there are the following different types of services: a) a service that allows the ITS-S management entity to set I-Parameter values in a “(Virtual) Communication Interface” (CI, VCI), see ISO 21218; b) a service that allows the I
30、TS-S management entity to read I-Parameter values from a (virtual) CI; ISO 2013 All rights reserved 3 ISO 24102-3:2013(E) c) a service that allows a “Management Adaptation Entity” (MAE), see ISO 21218, to notify events to the ITS-S management, including changes in (virtual) CI I-Parameter values; d)
31、 a service that allows the ITS-S management entity to send a command to an MAE; e) a service that allows an MAE to send a command to the ITS-S management entity; f) a service for transmission requests of a management data packet; g) a service for reception notification of a management data packet. S
32、etting of I-Parameter values shall be built on the service MI-SET. Reading of I-Parameter values shall be built on the service MI-GET. Issuing of commands by the ITS-S management entity shall be built on the service MI-COMMAND. Issuing of commands by a CI or VCI shall be built on the service MI-REQU
33、EST. Transmission request and reception notification of management data packets shall be built on the services MI-COMMAND and MI-REQUEST. Event notifications shall be built on the service MI-REQUEST. Every request and confirm service primitive shall be identified by a CommandRef parameter. A value u
34、nique within the available number space shall be assigned to the request service primitive. The related confirm service primitive shall use the same number as provided in the related request service primitive. Management communications with the access layer in other ITS-SCUs shall be with Inter-ITS-
35、SCU communication PDUs “MI-rset”, “MI-rget”, “MI-rcmd”, and “MI-rreq” as specified in ISO 24102-4. Details of the service primitives shall be as specified in Annex A. 6.2 MI-SET 6.2.1 MI-SET.request The service primitive MI-SET.request allows setting of I-Parameters by the ITS-S management.

36、meters of MI-SET.request are as follows: MI-SET.request ( Link-ID, CommandRef, Sequence of I-Param ) Table 1 MI-SET.request parameter description Name Description Link-ID Unique identifier of a VCI/CI. CommandRef Unique cyclic reference number of command. - Number of subsequent elements I-Param. I-P
37、aram.No See ISO 21218. I-Param.Value See ISO 21218. An MI-SET.request is generated by the ITS-S management entity when I-Parameters specified in ISO 21218 shall be set. On receipt of MI-SET.request, the selected parameters shall be set if applicable.4 ISO 2013 All rights reserved ISO 24102-3:2013(E)
38、 6.2.2 MI- SET .c onfirm The service primitive MI-SET.confirm reports the result of a previous MI-SET.request. The parameters of MI-SET.confirm are as follows: MI-SET.confirm ( Link-ID, CommandRef, Sequence of Errors OPTIONAL ) The optional element “Sequence of Errors” shall be available once at lea
39、st one of the requested settings was in error. It may be available in order to acknowledge settings explicitly. T a b l e 2 M I - S E T . c o n f i r m p a r a m e t e r d e s c r i p t i o n Name Description Link-ID Unique identifier of a VCI/CI. CommandRef Unique cyclic reference number of command
40、. - Number of subsequent error messages. Errors.I-Par- amNo Parameter reference number for which Result.Code applies. Errors.errStatus Return/error code, see Table P.1. A request to set a defined “read only” I-Parameter shall be acknowledged with ErrStatus 7 “ACCESS VIOLATION”. A request to set an u
41、ndefined I-Parameter shall be acknowledged with ErrStatus 2 “INVALID PARAMETER NUMBER”. A request to set a defined I-Parameter with an illegal value shall be acknowledged with ErrStatus 3 “INVALID PARAMETER VALUE”. A request to set a defined I-Parameter with an illegal type of value shall be acknowl
42、edged with ErrStatus 1 “UNSPECIFIED FAILURE”. An MI-SET.confirm is generated by the MAE upon reception of a previous MI-SET.request. On receipt of MI-SET.confirm, the ITS-S management entity shall evaluate Errors, if applicable, and act accordingly. Details are outside the scope of this part of ISO
43、24102. 6.3 MI-GET 6.3.1 MI-GET.request The service primitive MI-GET.request requests reporting of I-Parameter values to the ITS-S management.
