14、2010(E) iv ISO 2010 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member bod
15、y interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrote
16、chnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by
17、 the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rig
18、hts. ISO shall not be held responsible for identifying any or all such patent rights. ISO 25112 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems. BS ISO 25112:2010ISO 25112:2010(E) ISO 2010 All rights reserved vIntroduction This International Standard is part of a family
19、 of International Standards for communications access for land mobiles (CALM) which specify a common architecture, network protocols and a set of air interface definitions for wireless communications using a number of wireless media, including cellular 2nd generation, cellular 3rd generation, 5 GHz,
20、 millimetre, infra-red communications, and mobile wireless broadband (MWB), over packet-based networks. The CALM architecture is also designed to include short range, short duration, low-latency communication systems such as European dedicated short-range communications (DSRC) and North American wir
21、eless access in vehicular environments (WAVE) based on IEEE 802.11. It is anticipated that other air interfaces will be added in the future. Generally speaking, the CALM architecture is designed to include air interfaces that provide some subset of point-to-point, vehicle-to-vehicle, and vehicle-to-
22、point communications over packet-based networks in the ITS sector. In particular, this International Standard provides additional specifications which wireless devices adhering to the mobile wireless broadband IEEE 802.16 standards must also meet to be CALM compliant. The requirements for transmissi
23、on of information over large distances using wireless technology are functionally very different from the requirements for European DSRC. Large volumes of data are required for purposes such as safety, traffic information and management, video downloads to vehicles for tourist information and entert
24、ainment and navigation-system-updates. In order to support such services, mobile units need to be able to communicate over longer ranges with access points or base stations, and the system must be able to hand over sessions from one access point or base station to another. CALM standards are explici
25、tly designed to enable quasi-continuous data communications, as well as data communications of protracted duration between vehicles and service providers, and between vehicles. It is important to note that the CALM architecture is specifically designed to support packet-based communications; support
26、 for circuit-switched communications is not included. The fundamental advantage of the CALM concept over traditional systems is the ability to support media independent handover (MIH), also referred to as heterogeneous handover, between the various media that can be included in a CALM system. Select
27、ion policies are supported that include user preferences and media capabilities in making decisions as to which media to use for a particular session, and when to handover between media or between service providers on the same medium. These handover mechanisms are defined within the CALM architectur
28、e International Standard (ISO 21217), the CALM IPv6 Networking International Standard (ISO 21210), the CALM medium service access points International Standard (ISO 21218) and the CALM communication and station management International Standard (ISO 24102). Handovers between access points using the
29、same technology and service provider use mechanisms that are defined within the particular medium specific CALM Standard. ITS applications that can be enhanced or are enabled by the CALM architecture include, among others, car-to-car and point-to-multipoint safety messaging, collision avoidance, upd
30、ate of roadside telemetry and messaging, probe data collection, general internet access, image and video transfer, infotainment, multimedia multicast, traffic management, monitoring and enforcement in mobile situations, and route guidance. For a general introduction to CALM architecture, refer to IS
31、O 21217. This International Standard provides definitions and procedures for the establishment and maintenance of an ITS communications session within a CALM system environment using a medium communication in accordance with IEEE 802.16 (mobile WiMAX/WiBro) and RFC 5121 Transmission of IPv6 via the
32、IPv6 Convergence Sublayer over IEEE 802.16 Networks. BS ISO 25112:2010BS ISO 25112:2010INTERNATIONAL STANDARD ISO 25112:2010(E) ISO 2010 All rights reserved 1Intelligent transport systems Communications access for land mobiles (CALM) Mobile wireless broadband using IEEE 802.16 1 Scope This Internati
33、onal Standard selects the options appropriate for CALM using mobile wireless broadband (MWB) techniques conforming to IEEE 802.16, and specifies the management interface requirements. CALM links are required for quasi-continuous, prolonged and short communications between vehicles and the roadside,
34、between vehicles, and between mobile equipment and fixed infrastructure points. Wherever practicable, this International Standard has been developed by reference to suitable extant standards, adopted by selection. Required regional variations are provided. Application specific upper layers will not
35、be included in this International Standard, but will be driven by application standards (which might not be technology specific). 2 Conformance In order to claim conformance with this International Standard, mobile wireless broadband techniques standardized using IEEE 802.16 protocols shall be estab
36、lished in full compliance with local telecommunications procedures and protocols for IEEE 802.16 in accordance with IEEE published standards, and shall comply with the requirements of ISO 21217 (CALM System architecture), ISO 21210 (CALM IPv6 Networking), ISO 21218 (CALM medium service access points
37、), and ISO 24102 (CALM management). 3 Normative references The following referenced documents are indispensable for the application of this document.
