水上移动业务标识码资源的管理——国际电联ITU-R M.585-4标准解读

Management of Maritime Mobile Service Identities-Deciphering Recommendation ITU-R M.585-4

水上移动业务标识码是水上无线电台的一项主要身份识别信息,在遇险搜救活动中扮演着重要角色,国际电信联盟高度重视这一有限资源的管理和使用,并为此制定了技术建议书。文中介绍了我国水上移动业务标识码管理的背景和现状,并通过分析水上通信技术及搜救作业新需求,对最新修订的ITU-R M.585-4技术建议书进行了解读,包括建议书的范围、总体要求,对船舶电台的标识码、海岸电台的标识码、参与搜救飞行器电台的标识码、AIS助航设施的标识码和母船救生筏通信设备的标识码分配和使用规则,以及对号码资源进行保护和重新启用的方法等。最后,文章提出了我国标识码管理适应新建议书规则及普及宣贯有关知识和政策的工作计划。

Maritime Mobile Service Identities （MMSI） is the main identification measure for maritime radio stations. They play a key roll in the operation of search and rescue （SAR） at sea. The International Telecommunication Union （ITU） lays great emphasis on the management and use of the limited resources, and issued relevant technical recommendations. This thesis introduces the background and conditions of the MMSI management in our country, analyses the new technology of maritime communication and requirements of SAR nowadays, deciphers the new version of the Recommendation ITU-R M. 585-4. It includes scope, general requirements, assignment and identification of ship station, coastal station, aircraft for the purpose of SAR, AIS, Aids to Navigation, craft associated with a parent ship, and the guidance on the conservation and reuse of MMSI. Finally, it comes to the conclusion that national new rules should be adapted to the new Recommendation and suggests an action plan.
