The work of preparing International Stand

14、ards 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 and non-governmental, in liaison with ISO, also ta

15、ke 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 Directives, Part 2. The main task of technical committees i

16、s 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 casting a vote. Attention is drawn to the possibili

17、ty that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

18、 rights reserved vIntroduction 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 communications interface definitions for wireless communications using different be

19、arer technologies, e.g. second and third generation cellular, 5 GHz microwave, 60 GHz millimetre-wave, mobile wireless broadband, and Infra-red communications. Other air interfaces may be added at a later date. These wireless communications interfaces are designed to provide parameters and protocols

20、 for broadcast, point-point, vehicle-vehicle, and vehicle-point communications in the ITS Sector. This International Standard determines the air interface parameters for CALM communications via 2G/2.5G cellular networks. CALM standards are explicitly designed to enable quasi-continuous communication

21、s as well as communications of protracted duration between vehicles and service providers, and between vehicles. 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

22、various media supported by CALM (e.g., cellular, microwave, mobile wireless broadband, infra-red, DSRC). Selection 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

23、between service providers on the same medium. These handover mechanisms are defined within the CALM architecture International Standard (ISO 21217), the CALM networking protocols International Standard (ISO 21210), the CALM medium service access points International Standard (ISO 21218) and the CALM

24、 management International Standard (ISO 24102). Handovers between access points using the same technology and service provider use mechanisms that are defined within the particular medium specific CALM Standard. ITS applications include the update of roadside telemetry and messaging, internet, image

25、 and video transfer, infotainment, multimedia multicast, traffic management, monitoring and enforcement in mobile situations, route guidance, car-to-car and point-to-multipoint safety messaging, maintenance management, and “yellow page” services among others. This International Standard provides def

26、initions and procedures for the establishment and maintenance of an ITS communications session within a CALM system environment using 2G/2.5G cellular communications.

27、s Communications access for land mobiles (CALM) 2G Cellular systems 1 Scope This International Standard determines the air interface for second generation (2G) cellular networks and 2G systems (e.g. using WAP and I-Mode type protocols) to be compliant to CALM, i.e., requirements that must be met bef

28、ore a 2G system can be incorporated into a CALM system. In particular, this International Standard specifies protocols and parameters that 2G systems shall include to support prolonged, long-range, high data rate wireless communication links in ITS environments where heterogeneous handovers or media

29、 independent handovers (MIH) are either necessary to maintain the link, or desirable as determined by media selection policies. This International Standard provides protocols and parameters for long range, medium speed wireless communications in the ITS sector using second generation cellular commun

30、ications. Wherever practicable, this International Standard has been developed by reference to suitable extant standards, adopted by selection. Required regional variations are provided. Specifically, for this International Standard, extant 2G systems, as defined by various international and nationa

31、l standards, are adopted by reference. Application-specific upper layers are not included in this International Standard, but will be driven by application standards (which may not be technology specific). 2 Conformance In order to claim conformance with this International Standard, cellular communi

32、cation shall be established in full compliance with local telecommunications procedures and protocols for the appropriate 2G/2.5G Standards, and shall comply with the requirements of ISO 21210, ISO 21217, ISO 21218 and ISO 24102 (see Clause 3). 3 Normative references The following referenced documen
