Virtual RAN vs Open RAN?

 Industri seluler saat ini sedang mendiskusikan Virtualized RAN (vRAN) dan Open RAN, tetapi sangat penting untuk membedakan antara kedua konsep ini karena keduanya mewakili pendekatan yang berbeda:

1. vRAN atau RAN Virtual

Dengan vRAN, perangkat keras radio berpemilik tetap seperti apa adanya, tetapi BBU digantikan oleh server COTS daripada menjadi perangkat keras BBU berpemilik. Perangkat lunak yang berjalan di BBU divirtualisasikan untuk dijalankan di server COTS mana pun. Tetapi antarmuka eksklusif antara radio dan BBU berbasis COTS tetap seperti apa adanya.

Jadi, meskipun fungsi RAN divirtualisasikan pada server COTS, antarmuka antara BBU dan RRU / RRH bukanlah antarmuka terbuka, sehingga perangkat lunak vendor mana pun tidak dapat bekerja dengan RRU / RRH kecuali antarmuka menjadi terbuka.

2. OpenRAN atau ORAN

Kunci dengan Open RAN adalah bahwa antarmuka antara BBU dan RRU / RRH adalah antarmuka terbuka, jadi, perangkat lunak vendor mana pun dapat bekerja pada RRU / RRH terbuka apa pun. Antarmuka yang lebih terbuka memungkinkan penggunaan radio satu pemasok dengan prosesor lain – yang tidak mungkin dilakukan dengan vRAN. Open RAN adalah gerakan untuk mendefinisikan dan membangun solusi RAN 2G, 3G, 4G, dan 5G berdasarkan perangkat keras dan perangkat lunak yang ditentukan vendor untuk tujuan umum dengan antarmuka terbuka di antara semua komponen.

Open RAN Merupakan pemisahan hardware dan software: hardware RRU/RRH menjadi hardware berbasis GPP atau COTS yang dapat dibeli dari vendor hardware ODM, OEM atau RAN manapun. BBU sama seperti dalam kasus vRAN

3.Kesimpulan

Ada perbedaan penting antara vRAN dan Open RAN, yang paling penting adalah inovasi yang akan diperkenalkan Open RAN dalam rantai nilai telekomunikasi. vRAN juga akan memperkenalkan fitur-fitur baru dan meningkatkan efisiensi peluncuran jaringan, tetapi Open RAN secara fundamental mengubah seluler rantai nilai infrastruktur dengan cara yang mencerminkan keragaman pemasok dan kecepatan inovasi yang mendefinisikan ulang pasar PC beberapa tahun yang lalu

5G Functional Split: RU, CU and DU

 Di era 5G, dengan mempertimbangkan tren virtualisasi RAN, cloudization dan sentralisasi, dan untuk mengurangi kapasitas fronthaul dan delay, base station 5G telah direstrukturisasi, terutama dibagi menjadi tiga bagian:

CU/DU

    RU: Ini adalah unit perangkat keras radio yang mengubah sinyal radio yang dikirim ke dan dari antena menjadi sinyal digital untuk transmisi melalui jaringan paket. Ini menangani ujung depan digital (DFE) dan lapisan PHY bawah, serta fungsionalitas beamforming digital. pertimbangan utama desain RU adalah ukuran, berat, dan konsumsi daya. Mereka ditempatkan di situs.
    DU: Perangkat lunak unit terdistribusi yang digunakan di situs pada server COTS. Perangkat lunak DU biasanya digunakan dekat dengan RU di lokasi dan menjalankan RLC, MAC, dan bagian dari lapisan PHY.
    CU, unit pusat, terutama mencakup lapisan protokol RRC, SDAP, dan PDCP, dan terutama bertanggung jawab atas fungsi tumpukan protokol RRC, PDCP non-real-time.
    CU dapat digunakan di cloud untuk mendukung penyebaran terintegrasi dari sinking UPF jaringan inti dan komputasi tepi. CU dan DU terhubung melalui antarmuka F1. Satu CU dapat mengelola satu atau lebih DU

DU bertanggung jawab atas lapisan waktu nyata 1 (L1, lapisan fisik) dan lapisan bawah 2 (L2) yang berisi lapisan tautan data dan fungsi penjadwalan.

CU bertanggung jawab atas fungsi L2 dan L3 (lapisan jaringan) non-real time yang lebih tinggi.

Q and A, What is E1 interface in 5G?

 What is E1 interface in 5G?

My friend: Hi Ibrahim, I have a question for you.

Me: Please, go ahead.

My friend: What is the function of E1 interface in 5G?

Me: The E1 interface connects the Centralized Unit Control Plane (CU-CP) to the Centralized Unit User Plane (CU-UP) in the case of CU splitting which is done mainly to optimize the location of different RAN functions according to different scenarios and performance requirements, so the CU can be further separated into its CP and UP parts.

My friend: So, E1 interface is carrying data and control information between CU-CP and CU-UP, right?

Me: No, it is only carrying control information to allow for the coordination between user plane and control plane functions in the CU as normally the user plane information will be directed from CU-UP towards the UPF via NG-U interface. Also, note that as per 3GPP 38.460, the E1 interface should be an open interface that allows for CU separation to happen between different vendors.

My friend: Thank you very much. You made it clear.

Me: You are most welcome

Is 5G protocol stack different from 4G?

 Is 5G protocol stack different from 4G?

My friend: Hi Ibrahim, I have a question for you.

Me: Please, go ahead.

My friend: Is there any difference between 4G and 5G protocol stack?

Me: Yes, they are different slightly. If you checked the protocol stack of the 5G control plane, you can find similar layers to the 4G control plane, however the protocol stack of the 5G user plane has an extra layer which is SDAP (Service Data Adaptation Protocol) which is used to map each QoS flow into a specific Data Radio Bearer (DRB) as QoS flow is a new concept introduced in 5G and was not available in 4G before.

My friend: So, same layers with same functions, right?

Me: No, it doesn’t mean same layers for 4G and 5G, that same functions are exist for both layers. For example, the PDCP layer in 5G has different functions than 4G such as in 5G, PDCP layer can do PDCP PDU routing for the so called split bearers in case of operating in dual connectivity mode and split bearer concept is not there in 4G, also RRC layer in 5G is responsible for on-demand system information and also RRC inactive state which are new concepts in 5G.

My friend: Thank you very much.

Me: You are most welcome.

Q and A, Is mobility in 5G different from 4G?

 Is mobility in 5G different from 4G?

My friend: Hi Ibrahim, I have a question for you.

Me: Please, go ahead.

My friend: I was wondering if mobility in 5G differs from 4G or they are the same?

Me: Actually, it is different little a bit.

My friend: But, how are they different?

Me: In 4G we have mainly mobility between cells, while in 5G we’ve mobility between cells and beams which is called beam switching as well. So, both the 5G BTS and UE must be capable of changing beams as the radio conditions change.

My friend: But, how beam and cell mobility are done in 5G?

Me: Beam switching is done inside each cell which is called intra-cell mobility which requires layer 1 and layer 2 procedures. While, mobility between cells or what is called inter-cell mobility involves a handover which requires layer 3 procedures. Cell level measurements can be the average of different beams measurement or the value of the strongest beam depending on the algorithm used by each vendor.

My friend: Thanks a lot. You made it clear.

Me: You are most welcome.

Vulnerabilities in LTE and 5G networks 2020

June 10, 2020

With new 5G networks, mobile operators face numerous challenges. One of them is the GTP protocol, used alongside SS7 and Diameter on core networks to transmit user and control traffic.
The problem for operators is that the GTP protocol can be exploited by attackers. Vulnerabilities leave the door open to denial of service and fraud.
To foresee GTP-related issues in the 5G context and outline preventive measures to ensure full 5G network protection, Positive Technologies has released its latest report on GTP security.
This is the concluding paper in our four-part research series on core vulnerabilities and threats in the mobile ecosystem. Operators can refer to it for a picture of GTP threats and expert recommendations on how to proactively counter fraud.

5G Spectrum Industrial Networks – Ericsson White Paper

5G Spectrum Industrial Networks – Ericsson White Paper
Leveraging communications service provider assets and expertise
Many industries are looking at 5G as the backbone of the Fourth Industrial Revolution. It is a golden opportunity for communications service providers (CSPs) to create and capture new market spaces by driving innovation, efficiency, and growth across various industries.
A key factor influencing the uptake of wireless solutions is the question of how to handle spectrum for industrial purposes, since reliable connectivity demands licensed spectrum. Some countries provide spectrum dedicated for industrial use, whereas others do not. The intention of this paper is not to discuss the pros and cons of such spectrum strategies, but rather to focus on industries with local radio coverage needs. It tries to show that whether licensed spectrum is set aside for industries or not, CSPs are in the prime position to optimally address these industrial connectivity needs with powerful 5G networks and business models focused on industries. For regulators intending to implement licensed spectrum dedicated to industrial use, this paper aims to describe how this should best be done using simple principles and the well-defined legislation already available in most countries across the world.
Cellular solutions for industries — huge business potential
There is a huge opportunity for CSPs to address industrial connectivity needs with 3GPP-based cellular technologies. The opportunity encompasses a range of industries, including diverse segments with
diverse needs, such as those in the manufacturing, mining, port, energy and utilities, automotive and transport, public safety, media and entertainment, healthcare, and education industries, among others. Many enterprises in these industries are already CSP customers, with the total CSP share of the global addressable 5G-enabled market across these industries projected to be around USD 700 billion by 2030, according to the 2030 Market Compass Report.
One of the objectives of this paper is to address concerns regarding spectrum access for those industries that are early adopters of 3GPP cellular technologies for limited areas — in particular, industries such as manufacturing, mining, and ports as well as those with the opportunity to use cellular technologies in their operations but which have not seen wide adoption yet, such as the airport, oil and gas, warehousing, hospital, education, and construction industries.
Taking manufacturing, with its estimated 1 million factories (with more than 100 employees), as an example, typical business cases revolve around controlling the production process, improving material management, improving safety, and introducing new tools. Typical revenue increases come from increased throughput and quality (2–3 percent), while typical cost savings stem from improved capital efficiency (5–10 percent) and decreased manufacturing costs (4–8 percent). Additionally, ABI Research has shown that manufacturers can expect to see a tenfold increase in their returns on investment (ROIs) for cellular Industry 4.0 solutions, while warehouse owners can expect a staggering fourteen-fold increase in ROI.
