Anotace

Description / Abstract: ISO 21213:2008 determines the air interface options applicable to CALM using third generation (3G) cellular networks. In particular, it specifies protocols and parameters that 3G systems shall include to support prolonged, long-range, high data rate wireless communication links in ITS environments where heterogeneous handovers or media independent handovers (MIH) are either necessary to maintain the link, or desirable, as determined by media selection policies. ISO 21213:2008 provides protocols and parameters for long range, medium speed wireless communications in the ITS sector using third generation cellular communications. Wherever practicable, ISO 21213:2008 has been developed by reference to suitable extant Standards, adopted by selection. Required regional variations are provided. Specifically, for ISO 21213:2008, extant 3G systems, as defined by various international and national standards, are adopted by reference. Application specific upper layers are not included in ISO 21213:2008, but will be driven by application standards (which may not be technology specific).
