标准摘要
[中文适用范围]： 本国际标准选择适合使用符合 ATIS 0700004-2005 (HC-SDMA) 空中接口和 ITU-R M.1801 推荐的协议规范的移动无线宽带 (MWB) 技术的 CALM 的选项，并指定管理接口要求。 车辆与路边、车辆之间以及移动设备与固定基础设施点之间的准连续、长时间和短时间通信需要 CALM 链路。 在可行的情况下，本国际标准是参考适当的现有标准制定的，并经选择采用。 提供了所需的区域差异。 应用程序特定的上层不会包含在本国际标准中，但将由应用程序标准（可能不是特定于技术的）驱动。 [外文原描述]： ISO 25113:2010 selects the options appropriate for CALM using mobile wireless broadband (MWB) techniques conforming to ATIS 0700004-2005 (HC-SDMA) 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 communications between vehicles and the roadside, between vehicles, and between mobile equipment and fixed infrastructure points. Wherever practicable, ISO 25113:2010 has been developed by reference to suitable extant standards, adopted by selection. Required regional variations are provided. Application specific upper layers will not be included in ISO 25113:2010, but will be driven by application standards (which might not be technology specific).
