Our High-Performing Core Network
Fully virtualizable on VMware, K8S, Docker and OpenStack containers
IP Multimedia Subsystem(IMS)
IP Multimedia Subsystem(IMS) is a new mobile network infrastructure, a new way to deliver rich real-time communication services (voice, video, data, etc.) for both consumers and business users over any access network, especially VoLTE(Voice over LTE), Wi-Fi calling and VoNR(Voice over NR).
Key Benefits
100% cloud implementation of IMS core deployment
Convergence of mobile and fixed access networks
Deliver seamless, uninterrupted roaming
Support hypervisor and dynamic lightweight Linux Containers
Simplify managing interconnect network topology
Carrier Grade Reliability Support for multimedia services
IPLOOK's Virtualized IMS Enable voice services on any 4G, 5G and other data-only networks
- IPLOOK’s IMS system is 100% compliant (3GPP) and SIP-based. The product meets the VoLTE/VoNR service function of the operator’s LTE/5G network and can also cooperate with the dedicated EPC as a multimedia service function under the dedicated network.
- Our fully virtualized IMS solution is based on lightweight containers (Docker Swarm, Kubernetes) and runs on any public or private cloud (e.g. Oracle, Amazon, RedHat, etc.) as well as on hardware.
- Our IMS solution has been integrated with the hardware and software of all industry suppliers. This provides the highest possible flexibility to integrate with both industry structure and innovative (open-source) applications.
Features
Comply to 3GPP R14 Standard
Application Servers
- IP-SM-GW: Provides SMS services for VoLTE and exciting devices and allows interworking towards other networks based on SMPP
- MMTel/TAS: Provides rich supplementary services, e.g., call forwarding and call barring and acts as a conference-factory for VoLTE handsets
