One Physical Network.
Infinite Dedicated Pipelines.

Network slicing (3GPP Rel-15/16, SA5) partitions a single 5G SA infrastructure into isolated virtual networks — each with guaranteed latency, bandwidth, and reliability SLAs. HCT designs, deploys, and manages multi-tenant sliced networks for the most demanding operational environments in the UAE.

Three Slice Types

URLLC. eMBB. mMTC. One Network Serves All.

3GPP defines three distinct service categories for 5G NR. HCT configures each as an isolated slice on a shared 5G SA core — with different QoS profiles, dedicated UPF paths, and independent SLA guarantees.

SHARED 5G NR RADIO ACCESS NETWORK (Physical Layer)

QoS Profiles

5QI Parameters HCT Configures Per Slice

5G QoS Identifiers (5QI) define the scheduling priority, delay budget, and error rate for each traffic class within a slice. HCT tunes these per application, not per slice type generically.

HCT Slice Capabilities

Engineering Slices That Hold Their SLAs

🔧
Slice Design and Dimensioning
HCT radio engineers model slice capacity using stochastic geometry and 3GPP capacity formulas. We calculate UE density, PRB allocation, inter-slice preemption policies, and dedicated UPF N6 routing before a single rack is racked.

🏷️
NSSAI / S-NSSAI Configuration
Every slice is identified by a Service Type (SST) + optional Slice Differentiator (SD). HCT configures the NSSF (Network Slice Selection Function), NSSAI whitelists per UE group, and PCF policies per S-NSSAI — so each device connects only to its authorized slice.

📊
Per-Slice SLA Monitoring
Real-time KPI dashboards track latency, reliability, and throughput per slice via O1 telemetry. Automated SLA breach alerts with root cause identification — RAN congestion, core UPF saturation, or backhaul bottleneck — within 30 seconds.

Slice Isolation and Security
Dedicated UPF per sensitive slice ensures zero data leakage between OT and IT traffic. IPSec tunnel between gNB and slice-specific UPF. VLAN/VRF separation at transport layer. Slice-level firewall policy enforced via PCF/SMF rules.

Dynamic Slice Management via NSMF
HCT deploys a Network Slice Management Function (NSMF) integrated with our IoP orchestration layer. Operators can create, resize, and terminate slices via API or dashboard — no manual core config changes required. Slice lifecycle: under 2 minutes.

🚧
Roaming and Handover Between Slices
UEs that need multiple service types (e.g., a patrol vehicle needing MCPTT and HD video) maintain concurrent URLLC and eMBB slice bearers. HCT configures multi-slice UE registration and seamless handover without slice re-establishment.
