【摘要】 二十世纪九十年代以来,以计算机和通信技术为核心的信息技术迅猛发展,在社会各个领域引发了深层次的变革,加速了人类迈向信息社会的步伐。随着移动通信技术的快速发展和相关产品的更新换代,藏文移动电话呈现出广泛的市场需求。但由于目前支持藏文信息处理的移动通信终端种类非常少,无法满足广大人民群众物质文化生活的实际需要。因此,本文结合藏文信息处理技术的最新成果和移动通信终端研发的相关技术,研究了移动电话上实现藏文信息处理的相关技术和方法。该研究对将来藏族群众使用现代化通讯手段进行信息交流和沟通,使广大农牧民群众享受现代科技成果、共享信息文明,从而为缩短城乡差距、解决“数字鸿沟”、促进我区经济文化发展具有重大意义。本研究围绕以上主题,首先对目前藏文信息处理技术的发展状况进行了全面的回顾和分析,提出了藏文信息技术发展的四个阶段。其次对藏语言文字的特点和文法进行了深入研究,归纳出其特有的一些规律。最后提出了移动电话上实现藏文信息处理的以下方法:移动电话藏文编码方法。在研究藏文信息国际国家编码标准和手机操作系统所采用编码标准的基础上,利用索引技术提出了既符合藏文国际编码标准又能够满足手机编码要求的移动电话藏文编码方法。移动电话藏文字库制作方法及显示方法。这里,首先根据移动电话藏文信息处理的需要,对藏文字符进行了筛选,确定了移动电话信息处理所需的藏文字符,然后根据藏文印刷字体的书写特点和美观度要求,提出了移动电话藏文点阵字符取点方法和字库制作技术以及藏文字符的显示方法。移动电话藏文键盘布局设计及移动电话藏文输入法算法及实现方法。根据移动电话的键盘键位特点和藏文字符的构成要素,设计了移动电话藏文键盘布局,并结合具体某款移动电话终端的开发平台,提出了移动电话藏文输入法算法和实现方法。移动电话藏文短信编码与解码方法。在全面分析目前移动电话短信编码与解码技术和手机短信SMS规范的基础上,结合藏文编码索引方法,提出了移动电话藏文短信编码和解码方法。更多还原

【Abstract】 At the end of the 20th century, a great revolutionary, with the rapid development of information technology computer, whose core is computer and communication technique, influence all aspects of our society and speed up the development of information technology. Meanwhile, with the development of mobile communication technology and its product replacement and update, the market demand for Tibetan mobile telephone is increasing. However, due to the lack of mobile communication terminals which support Tibetan information processing, the current mobile telephone market can not meet the growing material and cultural needs of the people.Therefore, the relevant technologies and methods are studied in this article to reach the goal that Tibetan information technology can be implemented on mobile phones. The results of this study will make communication easier and convenient for Tibetans; especially benefit Tibetan farmers and herders. It will also reduce the city and countryside disparity in Tibet, resolve the problem of ’digital divide’, and promote economic development.The study described and reviewed the current Tibetan information technologies. The four phases of Tibetan information technology development are explored, in addition, Tibetan characters and grammars are studied in depth and some unique rules of Tibetan language are summarized. Finally, the following methods to implement Tibetan information technology on mobile phone are proposed:Tibetan character coding for mobile phone. a Tibetan character coding method, using index technique, is proposed and accord with international-standard Tibetan character code as well as the requirements of coding standards for mobile phoneCreating Tibetan character library and its display. In terms of the requirements for Tibetan information processing for mobile phone, we confirm the Tibetan characters with the filtration techniques in their search and present the methods to generate dot matrix for Tibetan character, create Tibetan character library and display the text on the phone.Tibetan keyboard layout design and Tibetan input method algorithm. According to the key mapping feature for mobile phone keyboard and the structure of Tibetan character, we designed the Tibetan keyboard layout for mobile phone, and proposed Tibetan input method algorithm and its implement with specific development platform of mobile phone terminalsEncoding and decoding for Tibetan short message. The study had a comprehensive analysis of decoding and encoding techniques for mobile short messages and the specification of SMS. The Approaches to decode and encode Tibetan short messages are suggested by combining code index technique for Tibetan character.更多还原
