Your revenue runs on LTE, your roadmap says 5G Standalone, and part of your base still depends on 2G and 3G: basic phones, M2M modules, roamers, voice fallback. You need a core that takes you to 5G SA without dropping any of them.
Ouroboros team has the perfect command of value-added services. We are pleased to enjoy a very high level of technical discussions and simple relationships with an available team and a great flexibility in solutions and process.

Your LTE network carries the traffic and the revenue. 5G Standalone is the next step: network slicing, low latency, new enterprise and IoT services. But 5G coverage will grow city by city for years, so every 5G device keeps moving between 5G and 4G, and the two cores must hand sessions to each other without breaking calls or data.
At the same time, you cannot switch off your 2G and 3G customers. Basic phones, payment terminals, meters and trackers, inbound roamers and CS voice fallback still need an HLR, an MSC, SMS and USSD. The usual vendor answer is a separate 5G core next to the existing one, a second subscriber database, and an integration project between them.
The AMTP platform runs every generation on one software base. The vEPC already separates control and user planes (CUPS), so the same gateways become the SMF and the UPF of your 5G SA core. The AMF and the MME interwork over N26, and the SMF stays the session anchor in both directions, so subscribers keep their sessions and IP addresses when they move between 5G and 4G.
HLR, HSS and UDM share one subscriber database: a customer is provisioned once for 2G, 3G, 4G, IMS and 5G. Your 2G/3G network keeps running on the same platform, with the smartMSC, SGSN, SMSC, USSD and STP, until you decide to retire it. Everything runs on COTS servers, VMware, KVM, Kubernetes or cloud, on OPEX rental or CAPEX licence.
The 4G core in CUPS: MME, SGW and PGW, ready for 5G interworking.
4G to 5G SA on the same platform: CUPS gateways become SMF and UPF, N26 keeps sessions across generations.
One subscriber database for 2G, 3G, 4G, IMS and 5G: no second provisioning chain for the 5G core.
2G/3G customers stay served while you move forward, and you retire the legacy network on your own schedule.
Proven with operators you can check: Salt Mobile, STC, Orange, Maroc Telecom.
Tell us your 4G core, your 5G SA timeline and what still runs on 2G and 3G. We will map the path: which elements to add, how 4G and 5G interwork, and how long your legacy customers stay served.
