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).
A complete, affordable, and fully customizable MVNO solution is now a possibility after IPLOOK IMS and P-GW perform a successful 3GPP-compliant interoperability test with the PortaBilling platform from PortaOne.
VoLTE provides five benefits over traditional CS voice calls: Migration to IP, Voice Quality, Fast Call setup, Multimedia communications and Efficiency.
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
» 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
Interfaces:
» Rx: Between PCRF and P-CSCF
» ENUM: Between S-CSCF and ENUM-DNS server
» Sh: Between AS and HSS
» ISC: Between AS and CSCFs
» Gm: Between SBC/P-CSCF and UE (via EPC/PGW)

I/S/P-CSCF, BGCF, SBC, AS NE Functions
» I-CSCF: Provides full Cx/Dx interface support and selects S-CSCF based on user capabilities and load
» S-CSCF: Provides flexible application execution using a standards-based ISC interface and allows optional charging integration with standard Ro/Rf interfaces
» P-CSCF: Provides full transcoding support for AMR/AMR-WB based on a separated RTP worker
» BGCF: Adds interworking functions (flexible in- and outbound routing options) and provides topology hiding
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
The Mission Critical Services(MCX) is being designed to interoperate with legacy LMR networks for integrated MCPTT voice, MCVideo and MCData capabilities.
The network architecture consists of:
▫ MCS: Provide MCPTT, MCVideo, MCData as 3GPP standard, including Identity Management Server(IDMS), Group Management Server(GMS), Configuration Management Server(CMS), Participating Function(PF), Controlling Function(CF), Key Management Server(KMS), Interworking Function(IWF)
▫ Unified operation and maintenance: Provide a unified operation and maintenance platform for MCS
▫ Unified dispatch: Provide a unified dispatching platform for MCS
VoLTE (Voice over LTE) is a voice service based on IP Multimedia Subsystem(IMS). It is an IP data transmission technology that does not require 2G/3G network and all services are carried on 4G network, which can realize the unification of data and voice services under the same network.
Voice over New Radio (VoNR) is the IP Multimedia System (IMS) based voice calling services based on 5G access, realizing both voice and data services carried on the 5G network.
The New Radio network communication is the 5G radio access technology and the advanced & updated form of 4G radio access technology.
