SI3000 IMS
The SI3000 IMS, implemented on the MEA or ATCA HW platform with Linux OS and Solid database, is the core element of the Iskratel IMS/VoLTE solution and provides session control functions (P-CSCF, I-CSCF, S-CSCF and E-CSCF), gateway control functions (AGCF, M-AGCF, BGCF and MGCF) and a media resource function controller (MRFC) on one physical element – the so-called IMS compact core & edge.
The bearer plane (IMS-MGW) is handled by the SI3000 SMG product, while the service layer (IM-SSF, AS) of the IMS network architecture is handled by the SI3000 AS, which gives you the means to easily expand the enablers and applications that make up the application development and service-creation ecosystem. The product provides interfaces (API) to the legacy network environment to allow existing services to be accessed and leveraged with new applications and Web 2.0 services.
All the functions are implemented according to the latest standards (3GPP, TISPAN) and regulatory requirements (ETSI LI, SORM).
The modular structure of the SI3000 IMS gives the carriers high flexibility in building the IMS network and means that all the implemented functions or only part of them are used, combined with other network entities.
The following very important aspects were also considered when designing the architecture of the SI3000 IMS product:
- Faster time2market with compact IMS core & edge
- Easy migration scenario for existing network, from NGN to pure IMS architecture
- Scalability, from very small scale to the high-end
The same SI3000 CS software solution is available on two HW platforms: ATCA platform - targeting larger capacities, and Iskratel´s proprietary MEA platform.
IMS Session Control Function / SI3000 IMS Core
- Proxy Call Session Control Function (P-CSCF)
- Interrogating Call Session Control Function (I-CSCF)
- Serving Call Session Control Function (S-CSCF) with integrated telephony application server (iTAS)
- Emergency Call Session Control Function (E-CSCF).
IMS Gateway Function / SI3000 IMS Edge
- Access Gateway Control Function (AGCF)
- Mobile Access Gateway Control Function (M-AGCF)
- Media Gateway Control Function (MGCF)
- Break Gateway Control Function (BGCF)
NGN Call Server / SI3000 CS
SI3000 IMS as NGN Call Server functionality supports Class-4, Class-5 and IBC functionality.
As Class 4 functionality:
- signaling and media gateways controll with MGCP or H.248
- support for SIGTRAN protocols (IUA, M2UA, M3UA, V5UA) and CAS protocols
- trunking with H.323, SIP, SIP-T/SIP-I
As Class 5 functionality :
- support of different SIP terminal equipments (softphones, deskphones)
- access gateways controll with MGCP or H.248 with support for analogue and ISDN terminals
- reach feature set support
As Iskratel Business Communication - IBC :
Connection to Iskratel’s application servers enables call server users an additional set of advanced services based on the NGN / IMS architecture. The existing business telephony services are enriched with
- self-care web portal
- single identity service
- address book
- presence status
- instant messaging
- file transfer
- video calling.
A unique dual mode SI3000 IMS compact core ensures seamless migration from NGN to IMS.
Application Server / SI3000 AS
SI3000 AS as an Application Server simplifies and eases the creation and deployment of converged services. It represents not only the abstraction layer to the legacy and SIP/IMS-based networks in the form of open application programming interfaces (API), but also the hosting platform for different applications, like widgets, web conferencing, among many others.
It is built according to a layered SDP architecture: each layer consists of independent components in the form of service enablers, network adapters (Diameter/Sh, RFC SIP and ISC/SIP) and open APIs that may evolve to follow not only market and technological developments, but also to be adapted for customized solutions.
The current trend is oriented toward gaining revenue from next-generation services (high-revenue-producing premium services), which include IMS's ability to integrate voice, data and content services. The flexible IMS platform enables carriers to build their own services and mix-and-match applications for a custom suite. End-users using premium services will increase ARPU as minutes of usage and megabytes of usage in the IMS world. For carriers who move toward an all-IP IMS-standardized network, the cost savings from reduced OPEX and CAPEX will come in a variety of forms:
- Build once, use many times
- Less expensive HW platforms
- Lower maintenance costs (fast ROI)
- Lower risk profile
- Less churn and easier to attract new subscribers
- Provide a complete infrastructure to deliver and provision innovative services and apps in the domain of telco
- Preserved roaming revenue
- Building on flexible and custom-made implementations
- IMS in the box
- Cost-effective migration that protects the investment
- Physical architecture that simplifies the network architecture, which results in lower CAPEX and OPEX
- Interoperability and coexistence of different technologies
- Possibility to integrate with different existing TDM access technologies (PSTN and PLMN) via AGCF and M-AGCF
- Built on 3GPP and ETSI standards
- Certification included
