سرعت 5G را افزایش دهید و برای عرضه نسل بعدی فناوری تلفن همراه آماده شوید. کتاب با مقدمهای بر 5G و ویژگیهای پیشرفته شبکههای 5G آغاز میشود، جایی که خواهید دید چه چیزی آن را بزرگتر، بهتر و سریعتر میکند. شما طراحی هسته بسته 5G NSA و SA را به همراه برخی چالشهای طراحی، با اتخاذ رویکردی عملی نسبت به طراحی و استقرار خواهید آموخت. در مرحله بعد، آزمایش هسته بسته 5G و نحوه خودکارسازی آن را خواهید فهمید. این کتاب با برخی از استراتژیهای ارائهدهنده خدمات پیشرفته، از جمله ملاحظات معماری برای ارائهدهندگان خدمات به منظور ارتقای شبکه خود و ارائه خدمات به شبکههای غیرعمومی 5G، به پایان میرسد. 5G Mobile Core Network برای کسانی در نظر گرفته شده است که مایل به درک 5G هستند و همچنین برای کسانی که به طور گسترده در یک محیط ارائه دهنده خدمات به عنوان اپراتور یا به عنوان فروشنده فعالیت هایی مانند طراحی شبکه، استقرار، آزمایش و اتوماسیون شبکه کار می کنند. در پایان این کتاب می توانید مزایای آن را از نظر CAPEX و OPEX درک کنید و در عین حال یک طرح را نسبت به طراحی دیگر در نظر بگیرید. مهندسان مشاور میتوانند گزینههای طراحی را از نظر موارد استفاده از 5G، مقیاس استقرار، عملکرد، کارایی، تأخیر و سایر ملاحظات کلیدی ارزیابی کنند. آنچه خواهید آموخت درک چرخه عمر یک استقرار درست از مرحله قبل از استقرار تا مرحله پس از استقرار مشاهده موارد استفاده از 5G و گزینه های مختلف برای طراحی، پیاده سازی و استقرار آنها. بررسی استقرار شبکه های 5G برای خدمات در مقیاس بزرگ ارائهدهندگان استراتژیهای MVNO/MVNE را که یک ارائهدهنده خدمات میتواند در 5G پیادهسازی کند، کشف کنید.
Get up to speed on 5G and prepare for the roll out of the next generation of mobile technology. The book begins with an introduction to 5G and the advanced features of 5G networks, where you’ll see what makes it bigger, better, and faster. You will learn 5G NSA and SA packet core design along with some design challenges, taking a practical approach towards design and deployment. Next, you will understand the testing of the 5G packet core and how to automate it. The book concludes with some advanced service provider strategies, including architectural considerations for service providers to enhance their network and provide services to non-public 5G networks. 5G Mobile Core Network is intended for those who wish to understand 5G, and also for those who work extensively in a service provider environment either as operators or as vendors performing activities such as network design, deployment, testing, and automation of the network. By the end of this book you will be able to understand the benefits in terms of CAPEX and OPEX while considering one design over another. Consulting engineers will be able to evaluate the design options in terms of 5G use cases, the scale of deployment, performance, efficiency, latency, and other key considerations. What You Will Learn Understand the life cycle of a deployment right from pre-deployment phase to post-deployment phase See use cases of 5G and the various options to design, implement, and deploy them Examine the deployment of 5G networks to large-scale service providers Discover the MVNO/MVNE strategies that a service provider can implement in 5G Who This Book Is For Anyone who is curious about 5G and wants to learn more about the technology.
