China Mobile's Fine-Granularity Segmentation Solution for 5G Network

At the 41st GTI Workshop, held from November 24-26 in Nanning, Guangxi, industry leaders gathered to discuss emerging trends and challenges in the telecom sector. Among the standout contributions was China Mobile’s presentation on its innovative "Built-in Micro-Segmentation Plus" solution for fine-granularity segmentation in 5G networks.

Jie Ma, Project Manager at China Mobile, outlined how this approach addresses escalating security challenges in increasingly decoupled and virtualized telecom environments. The evolution from 2G to 5G has seen continuous security advancements, including user authentication, signalling encryption, and network equipment security assurances. Yet, 5G's service-based architecture introduces new risks due to decoupled hardware, software, and virtualization layers, leaving networks vulnerable to lateral movement attacks.

China Mobile highlighted how the traditional security measures, such as firewalls and SDN gateways, provide perimeter protection but fail to address internal threats within a security domain. The decoupling of hardware, virtualization, and services in 5G—and even more in future 6G networks—exponentially increases the internal attack surface.

To mitigate these risks, China Mobile proposed the "Built-in Micro-Segmentation Plus" solution, which:

  • Monitors and Segments Internal Traffic: Enables segmentation at virtual machine (VM), container, and service levels, isolating unauthorized traffic and preventing lateral attacks.
  • Real-Time Attack Awareness: Integrates advanced traffic visualization and monitoring capabilities, identifying 15 types of potential attacks.
  • Policy-Driven Security: Uses a central management centre to define and enforce granular security policies across the network.
  • Enhanced Reliability: Incorporates features like hot backup, disaster recovery, and automated failure detection for uninterrupted service.

This innovative approach enables fine-granularity segmentation that extends security beyond the domain perimeter into the internal network fabric, addressing gaps left by traditional solutions.

In 2023, China Mobile successfully piloted the solution, validating capabilities like asset management, security policy management, and critical file tampering detection. The company plans to expand deployment across 200,000 virtual machines in its 5G core network by the end of 2024, aiming to set a benchmark in securing next-generation telecom infrastructure.

China Mobile’s "Built-in Micro-Segmentation Plus" exemplifies how operators can proactively tackle the security challenges posed by 5G and beyond. By integrating advanced segmentation and attack awareness capabilities, the proposal strengthens the telecom ecosystem’s resilience against evolving threats.

As the telecom industry moves forward, this solution not only highlights the importance of innovative security strategies but also underscores the collaborative efforts needed to secure the digital future.

Kuwait's Telecom Triumph: A Competitive Race to the 5G Frontier

Kuwait boasts a well-developed telecom infrastructure, particularly in mobile networks and services. The telecom sector plays a vital role in the country's economy, and its significance is expected to grow in the coming years as Kuwait strategically shifts from an oil and gas-dependent economy to one centred on knowledge, ICT, and related services.

Data from GSMA Intelligence shows that there were 7.89 million cellular mobile connections in Kuwait at the start of 2024. However, note that many people around the world make use of more than one mobile connection – for example, they might have one connection for personal use, and another one for work – so it’s not unusual for mobile connection figures to significantly exceed figures for total population.

GSMA Intelligence’s numbers indicate that mobile connections in Kuwait were equivalent to 182.2 percent of the total population in January 2024. The number of mobile connections in Kuwait increased by 279 thousand (+3.7 percent) between the start of 2023 and the start of 2024.

Kuwait has three mobile operators: Ooredoo, Zain and STC. The top two mobile operators, Ooredoo and Zain , accounted for 67.5% share of overall mobile subscriptions in 2023.

In Opensignal's latest analysis of Kuwait’s mobile network experience, Zain has emerged as the leading operator, winning 11 out of 13 awards this time — either jointly or outright. Zain claims outright victory in five categories, including Consistent Quality, Reliability Experience, 5G Download Speed and 5G Video Experience, while Ooredoo continues to lead outright in overall download and upload speeds, while sharing the top spot with Zain in four award categories, including Availability — the proportion of time users spend connected to mobile broadband services — for which all three operators are closely matched.

Ooredoo Kuwait, formerly Wataniya, emerged as the second mobile operator in the country, introducing competition and driving innovation within the sector. Ooredoo provides comprehensive nationwide coverage, with a particularly strong presence in urban areas. The company has invested heavily in its 4G LTE network and is aggressively expanding its 5G infrastructure. They are working with Huawei to move toward the ‘5.5G’, or 5G-Advanced, era by upgrading their core networks across key markets.

Ooredoo is known for its competitive data plans and generally good network quality. Users often praise their data speeds, particularly in urban centres, and their commitment to providing value for money. Ooredoo offers a diverse range of services designed to meet the evolving needs of its customers. 

Zain, originally known as MTC, is a trailblazer in mobile telecommunications in Kuwait and has grown into a leading regional operator with a presence across the Middle East and Africa.

Zain provides comprehensive nationwide coverage, reaching even the most remote areas of Kuwait. The company is a leader in network technology, offering extensive 4G LTE services and rapidly advancing its 5G infrastructure. Renowned for its superior network quality, Zain consistently earns praise for its fast data speeds, clear call quality, and minimal downtime.

Zain Kuwait began deploying 5G networks in 2018. After two years of development, 5G services have entered a phase of rapid growth. The user base continues to expand significantly, with a steady increase in the proportion of 5G traffic. This growth has driven positive revenue and profit gains for the operator.

Zain Kuwait has achieved a 5G subscriber penetration rate of 23%, with the average data usage (DOU) of its 5G users being five times higher than that of its 4G users.

Zain was the first operator to commercialize 5G networks in Kuwait. Zain provided the most extensive 5G coverage and best services owing to its focus on network construction. Zain has reached 100 percent coverage within six months of the commercial launch.

STC Kuwait, formerly Viva, entered the market as the third mobile operator, further intensifying competition and providing consumers with more choices. STC has been rapidly expanding its network, achieving nationwide coverage in a relatively short time. The company has been focusing on deploying 4G LTE and is actively rolling out its 5G network.

The mobile market in Kuwait is fiercely competitive, with Zain, Ooredoo, and STC actively competing for customer loyalty. This competitive landscape benefits consumers, as operators are compelled to offer appealing data plans, innovative services, and ongoing improvements to network quality and coverage. The recent introduction of 5G has heightened the rivalry, with each provider aiming to deliver the fastest speeds and the most advanced mobile experience.
