ITU-T L.1391 (01/2024)

توصيف تشارك شبكة الاتصالات المتنقلة الدولية-2020 (IMT-2020) والاشتراك في بنائها مواكبةً لتدابير تخفيف آثار تغير المناخ

‏توصف التوصية ‎ITU-T L.1391 ‏تقاسم شبكات الاتصالات المتنقلة الدولية-‎2020 (‏المعروفة أيضاً باسم الجيل الخامس) وبنائها على نحو مشترك (‎NSCC) ‏ومساهمتها في التخفيف من آثار تغير المناخ، وتحدد تكنولوجياتها الرئيسية وكيفية تقييم الشبكة NSCC ‏في تكيفها مع تغير المناخ. وتتناول التوصية ‎ITU-T L.1391 ‏أيضاً تحليل التكاليف والمنافع وأفضل الممارسات المتعلقة بالشبكة ‎IMT2020 NSCC.‏يواجه مشغلو الشبكات المتنقلة في جميع أنحاء العالم صعوبات غير مسبوقة في نشر الاتصالات المتنقلة الدولية-‎2020. ‏ونظراً للقيود الناجمة عن موارد الطيف باهظة الثمن، والحاجة إلى استثمارات كبيرة واستهلاك عالٍ للطاقة في الاتصالات المتنقلة الدولية-‎2020‏، فإن فجوة الأرباح بين المشغلين ومصنعي المعدات آخذة في الاتساع، وينشأ عدد كبير من المشاكل المتعلقة بزيادة الأعمال دون زيادة في الإيرادات.‎ ‏‏وتطرح أساليب خفض تكاليف بناء الشبكات وتشغيلها والتكيف مع تغير المناخ وتمكين الفوائد السريعة للاتصالات المتنقلة الدولية-‎2020‏، وخاصة في مناطق الاتصالات المتخلفة، تحديات كبيرة أمام الصناعة العالمية والمشغلين في العالم.‎
