11、bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental
12、and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directive
13、s, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by 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 c
14、asting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

BS ISO 29283:2011ISO 29283:2011(E) iv ISO 2011 All rights reservedIntroduction This International Standard is part of a family of International Standards for CALM (Communications Access for Land Mobiles) which specify a common architecture, network protocols and a set of air interface definitions
16、 for wireless communications using a number of wireless media, including cellular second generation, cellular third generation, 5 GHz, millimetre, infra-red communications, and mobile wireless broadband (MWB), over packet-based networks. The CALM architecture is also designed to include short range,
17、 short duration, low latency communication systems such as European Dedicated Short-Range Communications (DSRC) and North American Wireless 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 C
18、ALM architecture is designed to include air interfaces that provide some subset of point-to-point, vehicle-to-vehicle, and vehicle-to-point communications over packet-based networks in the ITS Sector. In particular, this International Standard provides additional specifications which wireless device
19、s adhering to the mobile wireless broadband IEEE 802.20 techniques standard must also meet to be CALM compliant. Large volumes of data are required for purposes such as safety, traffic information and management; video downloads to vehicles for tourist information and entertainment and navigation-sy
20、stem-updates, etc. In order to support such services, mobile units need to be able to communicate over longer ranges with access points/base stations, and the system must be able to hand over sessions from one access point/base station to another. CALM standards are explicitly designed to enable qua
21、si-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 for circuit-switched commu
22、nications 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. Selection policies are supported
23、that include user preferences and media capabilities in making decisions as to which media to use for a particular session, and when to hand over between media or between service providers on the same medium. These handover mechanisms are defined within the CALM architecture International Standard (
24、ISO 21217), the CALM IPv6 Networking for internet connectivity 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
25、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 car-to-car and point-to-multipoint safety messaging, collision avoidance, update of roadside
26、 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, just to mention a few. For a general introduction to CALM architecture, see
27、 ISO 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 the IEEE 802.20 protocol specification.

29、e IEEE 802.20 air interface and protocol specification recommended by ITU-R M.1801 and specifies the management interface requirements. CALM links are required for quasi-continuous, prolonged and short duration communications between vehicles and the roadside, between vehicles, and between mobile eq
30、uipment and fixed infrastructure points, over medium and long ranges. 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 are not included in
31、 this International Standard, but will be driven by application standards. 2 Conformance In order to claim conformance with this International Standard, mobile wireless broadband techniques standardized using the IEEE 802.20 protocol specification shall be established in full compliance with local t
32、elecommunications procedures and protocols for IEEE 802.20 in accordance with IEEE standards, and shall also conform to the requirements of ISO 21217, ISO 21210, ISO 21218, ISO 24102 and ISO 25111. 3 Normative reference The following referenced documents are indispensable for the application of this
