5G Core, Evolve from 4G to 5G Cost Efficiently

By Said Zantout
As 5G picks up speed, the new networks will co-exist with the existing 4G ones in the coming years. For Communication Service Providers (CSPs), flexibility in balancing cost-optimized versus performance optimized network deployment is crucial to maximize profitability and take advantage of the wide range of business opportunities.

Basically, it means they need to have the option to migrate to 5G in their own time and in alignment with their business needs.
The journey to 5G Core is not simple, though, and will imply a technology shift with the adoption of a new 3GPP defined network architecture (service-based architecture) and new network functions built on cloud native technology. With service providers’ needs and concerns in mind we have developed the dual-mode 5G Core solution.
Dual-mode 5G Core provides that kind of desired control by combining Evolved Packet Core (EPC) and 5G Core network functions into a common cloud native platform. CSPs can get the most out of cloud native, microservices and user plane performance by implementing the dual-mode core solution as the best way for efficient control of Total Cost of Ownership (TCO) while smoothly migrating to 5G.
As hard as it sounds to achieve challenging business and operational goals while migrating to a 5G Core, with dual mode it is possible.
If we look at Ericsson’s dual mode 5G Cloud Core solution, it is fully based on cloud native principles, with software architecture being based on microservice technology.
This is to ensure that the underlying infrastructure will have better capacity and elasticity, which in turn will offer high levels of orchestration and automation for operational efficiency.
Dual-mode solution enables CSPs to manage one network instead of two and add programmability to their network. The decomposition of software into microservices facilitates a fast, low-cost method of introducing new services on a small scale.
At the same time, it supports easy and effective scaling of services from hundreds of users to millions and this is exactly how CSPs can address new business opportunities or pursue those that have been difficult to address until now.
While no journey to a future core will be alike, what applies to every CSP is the need to have a holistic view on cost. A report by Ericsson titled “Dual-mode 5G Cloud Core: TCO benefits” highlights that substantial saving is possible in various areas of dual-mode cloud native operations, including:
— Up to 20 percent of capex in Core network infrastructure
— Up to 15 percent savings in database infrastructure
— 70 percent OpEx savings in configuration of policies
— Up to 80 percent cost savings in network integration
— More than 60 percent reduced OpEx for software upgrades
As 5G evolves, dual mode core supports both Evolved Packet Core (EPC) and 5G core, combining both functionalities and offering a uniform operational maintenance that is able to scale with the speed that 5G use cases demand.
Migrating to a 5G NR SA and 5GC network is crucial for our customers’ success, enabling them to unlock key 5G functionalities like faster speeds, ultra-low latency and advanced network slicing – allowing our customers to support increasingly complex 5G use cases such as automated manufacturing, remote healthcare and connected vehicles.
This migration will also allow service providers to simplify operations and service agility, enhance user experience with better coverage and improve network capabilities.
To secure new 5G revenue streams while continuing to support existing 4G customer base, service providers can begin by introducing 5G New Radio (NR) non-standalone (NSA) and run both generations side by side supported by the Evolved Packet Core while migrating to 5G NR standalone (SA) and a 5GC network.
At Ericsson, we have been learning from previous technology shifts. As we enter 5G era with all its complexity and unknown opportunities, we know the value of migrating networks at own pace and dual-mode 5G Cloud Core solution provides enhancements that enables this vision.
By implementing the dual-mode solution, service providers will have more control to migrate to 5G on their own pace and in alignment to their business needs.

9mobile Nigeria Inks Agreement to Roam with MTN

9mobile, Nigerian operator, has reportedly gained approval for roaming on the MTN Nigeria network in a deal that some commentators suggest could improve its position in the market and, more specifically, tempt back lost subscribers.
After finally gaining regulatory approval from the Nigerian Communications Commission (NCC), 9mobile plans to launch national roaming services on the MTN network from this month.
Under the agreement, 9mobile subscribers will gain access to MTN’s infrastructure for calls, texts and data in areas where 9mobile’s coverage is weak or unavailable.
For 9mobile, the deal offers a cost-effective way to expand coverage without the heavy investment required for nationwide infrastructure.
According to ITWeb Africa, the decision comes nearly five years after initial discussions – much longer than expected due, the Techloy news service said, to regulatory bottlenecks, shifting market conditions, and unclear execution timelines.
It may, however, prove pivotal for 9mobile, whose market share has dwindled to 1.72% in April 2025, down from 6.6% in 2020 when the proposal was first submitted. Indeed, in 2015 the company once known as Etisalat Nigeria had over 23 million subscribers and a 15.7% market share.
Of course, there’s also something in this for MTN. In exchange for network access, MTN gains utilisation rights to 9mobile’s underused spectrum in the 900MHz, 1800MHz, and 2100MHz bands – key frequencies for expanding coverage and improving data capacity.
For MTN, which serves over 84 million subscribers, this additional spectrum could reduce congestion and improve service quality.
The company has also had financial difficulties in the Nigerian market due to the naira’s substantial depreciation; this deal could support better service provision at a reduced cost.
That said, MTN Nigeria’s results for the first quarter to March 31 2025 were apparently much improved, and the company recently announced a massive capital expenditure drive for 2025 of some NGN900 billion (US$568.5 million) as it seeks to significantly enhance network service quality in major cities like Lagos and Abuja and extend improvements to other areas.

Banks, Telcos to Start Deducting USSD Charges from Airtime Today

Banks and telecom companies will begin deducting USSD banking charges directly from customers’ airtime instead of their bank accounts beginning from today, June 3.
USSD, otherwise Unstructured Supplementary Service Data, is a communications protocol used by GSM cellular telephones to interact with a mobile network operator’s computers.
First City Monument Bank (FCMB) announced this change in an e-mail message to customers, following a directive from the Nigerian Communications Commission (NCC).
Key details:
Each USSD session will cost ₦6.98 per 120 seconds, charged by your mobile network.
You will be asked to approve the charge before it’s deducted from your airtime.
If you prefer, you can use other banking channels like ATMs, mobile apps, or internet banking.
This change is part of a move to end the long-standing debt dispute between banks and telecoms over unpaid USSD fees.
As of late 2024, banks owed telecom companies ₦160 billion. For example, MTN was owed ₦42 billion by Nigerian banks.
By shifting USSD fees to customers’ airtime, the telcos aim to recover these debts and avoid future issues.
