What Fixed-Mobile Convergence Means for Telcos in 2025 and Beyond

Why Fixed-Mobile Convergence Is Back in Focus

FMC or fixed-mobile convergence is a term we use to explain the integration between fixed infrastructure and mobile communication networks. Through FMC integration, we can access multimedia services, as well as voice and data transmission. Telecommunications companies benefit from this technology, as it enables them to offer a more comprehensive experience to users.

The reason why operators are turning to fixed-mobile convergence FMC in 2025 is due to the fact that users' behavior has changed drastically in recent years. Instead of traditional networks, people are looking for hybrid solutions for their daily business communications.

With the development of technologies such as Wi-Fi 6E/7, 5G standalone, and multi-access edge computing, adopting FMC has never been easier or more profitable. FMC allows users unified communications for remote and hybrid work, thus optimizing resources for operators. Telcos are able to streamline enterprise communications, allowing access to both fixed and mobile devices.

As one of the biggest global providers of core network solutions, Titan.ium is well-suited to support fixed-mobile convergence.

What Is Fixed-Mobile Convergence in Telecom?

FMC technology effectively integrates mobile (cellular networks and services) and fixed (broadband networks and services) technology. As a result, operators can introduce a wider variety of telecommunication services to both private and business users, regardless of whether they use a fixed line or a mobile phone.

The technology allows operators to achieve several business objectives, ensuring uninterrupted sessions for their users. They can easily charge clients through a unified system, which not only simplifies billing but also allows the creation of combo packages. The last advantage is the centralization of user data into a single source.

Back in the day, fixed and mobile networks worked separately, relying on different silo infrastructure. However, as more users demand simplified access across cell phones and fixed devices, this model is no longer effective. Combining fixed and mobile technology also reduces operational costs for operators, ensuring they stay competitive in the market.

Why Telcos Are Prioritizing Convergence in 2025 and Beyond

There are several reasons why operators have started prioritizing seamless connectivity in 2025 and beyond:

• Market Pressure: In the last few years, many operators have seen their revenues stagnate and even plummet. This is partially caused by increased competition from OTTs, like WhatsApp and Netflix, which circumvent the regular telecom revenue streams.
• Need to Reduce CapEx/OpEx: By consolidating fixed and wireless networks, businesses are able to minimize infrastructural costs. Through optimized use of company resources, telcos can now achieve much higher profits.
• Enhanced Customer Experience: Whether they're using smartphones, desk phones, or a different technology, customers are looking for seamless access without interruption. They want to have the same experience whether they're connecting to the internet through their own device or a company computer.
• Regulatory Pressure: More and more governments are in favor of FMCs as the technology allows a better user experience and a fair market. Furthermore, they see value in modernizing the traditional mobile and fixed networks. 
• Future-Proofing for AI: Unified communication sets the table for future technologies. As more and software relies on AI to deliver premium service, telcos have to update their workflows to enable artificial intelligence and machine learning solutions.

Challenges in Achieving Fixed-Mobile Convergence

Although profitable, achieving fixed-mobile convergence is much harder than it might seem:

• Disparate Subscriber Data Systems: Broadband and mobile networks use different systems for handling user data. As a result, integrating AAA and HLR/HSS technology often creates a new set of problems.
• Siloed Policy and Charging Functions: Many companies use different charging functions and policies for their fixed and mobile networks. This commonly leads to issues with billing and app/service management.
• Vendor Lock-In: Older networks often struggle with vendor lock-ins, restricting the adoption of new technology
• Complexity of Multi-Protocol Interworking: Operators must find ways to handle different protocols, such as MPLs and IP, which makes the transition that much harder.

• Security Considerations: Given that we're talking about two completely different systems, operators often struggle to create a new network without compromising security. Transitioning from one network to another opens numerous vulnerabilities, while also affecting session continuity.
