趣話通信：6G的前世、今生和未來

通信行業(yè)是當(dāng)今社會的熱門行業(yè)，本質(zhì)上，通信其實是人類活動的極其重要的輔助手段。隨著近代各項技術(shù)的進步，通信技術(shù)的發(fā)展也是在一代一代地更新迭代發(fā)展壯大。本書從人類發(fā)展中最原始的語言開始，描述了通信的作用，概要介紹了通信的基礎(chǔ)，特別是無線通信的發(fā)展簡要歷程，到如今的5G技術(shù)以及不久到來的6G技術(shù)等，后續(xù)也暢想了未來的通信和其他技術(shù)的發(fā)展方向，并把7G、8G之后的時代歸結(jié)為6G＋時代。期待隨著通信等人類可用工具的高度發(fā)達，人類的活動領(lǐng)域?qū)U展，各種生活方式也會隨之出現(xiàn)巨大變化。

全聯(lián)網(wǎng)標(biāo)識服務(wù)

物聯(lián)網(wǎng)的發(fā)展進入了一個新的時期，即“全球物聯(lián)網(wǎng)”（簡稱“全聯(lián)網(wǎng)”。全聯(lián)網(wǎng)是更加泛在的網(wǎng)絡(luò)體系，是一個一體化集成人、機（計算機）、物的，無處不在、始終在線的世界上最大的超巨系統(tǒng)。全聯(lián)網(wǎng)是最具廣泛性的基礎(chǔ)應(yīng)用和構(gòu)造一個人工智能驅(qū)動世界的切入點，是大數(shù)據(jù)、云計算、人工智能賴以持續(xù)發(fā)展的基礎(chǔ)，對數(shù)字經(jīng)濟和經(jīng)濟社會轉(zhuǎn)型帶來的效益最為顯著、影響最為直接和深遠(yuǎn)。隨著物聯(lián)網(wǎng)、工業(yè)互聯(lián)網(wǎng)的發(fā)展，網(wǎng)絡(luò)空間標(biāo)識體系一方面不斷發(fā)展和完整自身的技術(shù)標(biāo)準(zhǔn)體系，另一方面也不斷拓寬其應(yīng)用領(lǐng)域，深化與已有應(yīng)用的合作。快速的發(fā)展也帶來一些相應(yīng)的問題：傳統(tǒng)標(biāo)識系統(tǒng)能否適應(yīng)全聯(lián)網(wǎng)的發(fā)展；異構(gòu)標(biāo)識各自獨立發(fā)展如何解決信息孤島問題。在全聯(lián)網(wǎng)時代，如何有效的解決這些問題，同時對海量實體（人、機、物）及內(nèi)容和服務(wù)提供安全、智能、高效、泛在、可控的標(biāo)識管理體系與解析機制，是極具挑戰(zhàn)且亟需探索的問題，是全聯(lián)網(wǎng)復(fù)雜巨系統(tǒng)中需要優(yōu)先思考布局的核心問題和難點問題。在國家信息化專家咨詢委員會周宏仁常務(wù)副主任及專家組其他專家的指導(dǎo)下，CNNIC研究和提出了全聯(lián)網(wǎng)標(biāo)識解析技術(shù)總體架構(gòu)設(shè)計并進行了系統(tǒng)關(guān)鍵技術(shù)可行性驗證。本書第一章回顧了從物聯(lián)網(wǎng)到全聯(lián)網(wǎng)的發(fā)展歷史；第二、三章對全聯(lián)網(wǎng)的標(biāo)識需求、設(shè)計原則及關(guān)鍵技術(shù)進行了調(diào)研；第四到九章分別詳細(xì)綜述了主流標(biāo)識解析體系，包括DNS、OID、Handle、EPC、uCode、Ecode等；第十章提出了一種適用于全聯(lián)網(wǎng)的新型標(biāo)識解析架構(gòu)；第十一章就全聯(lián)網(wǎng)標(biāo)識解析技術(shù)如何推廣應(yīng)用進行了探討；最后一章對全聯(lián)網(wǎng)標(biāo)識解析技術(shù)的發(fā)展趨勢進行了展望。
