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
RKTPL's Virtualized IMS
Enable voice services on any 4G, 5G and other data-only networks
Enable voice services on any 4G, 5G and other data-only networks
RKTPL’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.
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
» MRF: Provides network announcements and conferencing. Implemented according to RFC4240 (Basic Media Services in SIP) and set up as combined MRF-controller (MRFC) and -processor (MRFP)
» SR-VCC: Enables seamless early or mid-call handover from 4G/5G to 2G/3G and acts as a media-anchor for voice calls
» LI: Provides X1 to X3 interfaces towards the mediation function
» I-CSCF: Provides full Cx/Dx interface support and selects S-CSCF based on user capabilities and load

- Secures the network edge for user access and/or peer network interconnection with topology hiding, Internet Protocol Security encryption (IPSec), Transport Layer Security (TLS), Secure Real-Time Transport Protocol (SRTP) and intrusion protection such as from Distributed Denial of Service (DDoS) attack
- Provides SIP signaling control and media anchoring to ensure voice call continuity for calls that traverse LTE and 3G networks
- Scale to millions of subscribers per service
- Enable the use of HD voice and EVS voice codecs, including transcoding, delivering a better quality of experience (QoE) for end-users compared to over-the-top (OTT) services
