Ensuring efficient interconnection between telecommunications operators is crucial for the quality and stability of the services offered to users. To improve this connection, here are three important tips: 1. Technological standardization: It's essential for operators to use standardized technologies and protocols, such as IP (Internet Protocol), to facilitate communication between them. This allows for greater compatibility and more efficient data transfer. 2. Peering agreements: Establishing peering agreements, that is, partnerships for mutual traffic sharing, is an effective strategy for optimizing interconnection. By directly interconnecting their networks, operators reduce latency and unnecessary traffic through third parties. 3. Continuous monitoring and maintenance: It's imperative that operators constantly monitor their interconnection to identify potential problems and ensure maximum efficiency. Scheduled maintenance and quick responses to failures are essential to minimize service interruptions. By adopting these tips, telecommunications operators can improve the quality of interconnection, ensuring a more satisfactory experience for telecommunications services users. Liked the post?

Access Network, also known as Radio Access Network (RAN), is a crucial part of the telecom network that deals with the "access" of users to reach the rest of the network and connect with it. This part has several Network Elements (NEs), each with its purpose, all to serve the ultimate goal of communication. The first NE in the Access Network is the User Equipment (UE), which is right in front of us; in our hands. The UE is the gate to enter the world of Telecommunication, connecting wirelessly with a desired radio frequency to BTS. It has the user's Interface applications and additional functions that are performed in various phases of Telecommunications with other Network elements. The Base Transceiver Station (BTS) is the gate between the User Equipment (UE) and the Network. It transmits and receives radio signals to and from the UE and converts them to digital signals to get through the Network. The Base Station Controller (BSC) acts as the controller of the Access Network, and it falls under its control a number of BTSs. It acts as a gateway as the actual physical link between the Access Network and the Core Network, by being linked directly with the Mobile Switching Center (MSC). Understanding the architecture of the Traditional (GSM) Network is the base of all the next generations of Networks. Stay tuned for our next post, where we will discuss the changes and differences in the upcoming generations. But for now, Which of the Access Network NEs do you think is the most important and a key player in communication, the UE which connects the users, or the BCS which controls it all? Let us know your thoughts in the comments below. Photo demonstrate the Radio Access Network components and its connection with the Core Network.

Backhaul of Legacy Mobile Networks: An Operator’s Nightmare and Great Headache Advancing to newer technologies also involves trimming down on older ones that do not?bring value anymore. There is a need to move beyond maintaining a plethora of legacy technologies that bog us down. The attached slides is just one of my views of what we are saddled with. Many network operators are still saddled with legacy TDM/pseudowire mobile technologies with interfaces based on E1/T1, SDH/SONET, ATM, IMA, etc. The CAPEX and OPEX implications of such support cannot be understated. Even a migration to IP/Ethernet core does not do away with the cell site gateway conversion cost to support such legacy mobile technologies.? The aim of the attached slides, only illustrative, is to show the nightmare and headache an operator faces in still maintaining such legacy technologies while migrating to the IP/Ethernet friendly technologies such as LTE/4G and 5G, and what G is next. Maintaining many parallel component and spare parts, specialized technicians/engineers, and operation and support systems for multiple legacy technologies all supporting a SINGLE?pool of customers, is something the operator cannot ignore.

Synchronizing more with less: The future of 5G/6G networks through advanced PTS standards As we move further into the era of 5G, the reality for many large operators is that achieving precise synchronization across their networks remains a significant challenge. Many operators rely on leased lines for coverage and reach, which complicates the implementation of Precision Time Protocol (PTP) with full timing support end-to-end. In addition, a large part of their networks does not support full timing support (FTS) PTP. Distributing PTP over such links is not feasible, making it impossible to maintain full timing accuracy across the network. Moreover, operating a full timing support PTP network where every network port is involved in the distribution of synchronization is very complex. Considering that large operators have hundreds of thousands of line cards and base stations, it's understandable that network upgrades can disrupt synchronization distribution, impacting overall performance. In response to these challenges, the International Telecommunication Union (ITU) is actively working on enhancing the PTP partial timing support standard through the new ePTS working item. Net Insight is at the forefront of this initiative, advocating for a disaggregated synchronization function like PTS synchronization, which interoperates with next-generation Open RAN (ORAN) and Cloud-RAN architectures. This approach is crucial for supporting the future requirements of 5G and 6G technologies and services, ensuring robust and reliable network performance in an increasingly complex and demanding environment. #NetworkSynchronization #5GInnovation #6GTechnology #TelecomSolutions #DigitalTransformation #FutureNetworks #AdvancedConnectivity #ePTS
