SI3000 MSCN: Solving the control-plane challenge For the past 15 years the world of telecommunications has been facing a new type of challenge. The infrastructure and technologies originally designed to carry only telephony services have needed to evolve to cope with the expanding world of multimedia and data services. New multi-service networks have had to be built on top of the legacy equipment of the PSTN, and it has been essential for this transition to be both smooth and cost effective. This transformation is referred to as the migration to Next Generation Networks, or NGNs.
Carriersâ€™ prospects for future growth With the transformation of traditional telephone PSTN services the carrier must focus on: - providing new, cost-effective services for a reinvented revenue stream, - preserving the existing services and regulative features with a new technology, - avoiding any degradation of the services or inconvenience to the end-user, - the possibility of functional scalability and capacity growth for newly deployed infrastructure. All these issues are an encouragement for a fixed-line voice-service provider to evolve existing voice nodes and other network elements.
The changes have to be seamless and gradual with no inconvenience to end-users in order to guarantee future benefits for the service provider. During the process of network transformation it is crucial the users receive the same services and the same user experience together with the possibility of new services and expiriences.
The right time and the right technology In an ideal situation the end-users would have the same user experience with the IP-based network as they had with the PSTN, although they will start to use new applications and services. Achieving such a situation is a challenging task, especially in suburban and rural areas where investments are very carefully chosen. The prediction of a telcoâ€™s future revenue structure suggests that telephony is losing importance as a stand-alone service and is becoming part of a broader communications service. Revenue tends to increase where the telcos are able to offer a full bundle of services - in addition to telephony this includes messaging and video communications. The deployment of new services is mandatory.

in the network
The SI3000 MSCN services The economics, threat and success of VoIP services have encouraged many service providers to accelerate their deployment. These VoIP services attracted users with their low prices for basic features. The answer to these challenges is to provide a service bundle like a multimedia VoIP service with rich features and a simple, easy-to-learn interface to use them. Residential customers are already attracted to VoIP services by competitively priced IP telephony bundles that include a variety of services, such as internet access, local telephony access, unlimited calling, voicemail, call waiting, and caller ID. With the increasing competition, service providers need to retain customers, and prevent their switch to internet-phone-service competitors. The social aspect of web-services usage will grow and this might boost traditional earning models, like talking on the phone and sending SMS messages. The behavior of customers is changing: the sharing of various content, such as pictures and video blogs, with friends and other people in the internet community has become increasingly common.
To reinvent a telco’s revenue stream firstly a cost-efficient platform has to be established. It demands an integrated, scalable, open-standard-based solution like the SI3000 MSCN. Additional CAPEX (Capital Expenses) reduction is achieved with the ease of administration, the ensured reliability and the efficient management of all the components.

BENEFITS OF LAYERED ARCHITECTURE: Revenue-driven network evolution Smooth deployment of new services Multi-vendor interoperability (IMS) Future proof
Call-completion services During an active call the user receives an incoming-call indication: - the call-completion network service offers the caller the possibility to set a call-back request as soon as the called subscriber is available again. - the standard call-hold service enables switching between active calls. - distinctive ringing and music-on-hold for userfriendliness of communications.
Call-offering services - Call forwarding – offers remote activation as a follow-me service, or on a spur-of-the moment decision as a call-deflection service. - Group call – the selected groups can distribute incoming calls in a sequential or linear mode or by ringing the whole group. - Call transfer – the call-transfer services are executed as a blind transfer during the ringing or as the termination of a consultation call. - Call-interception scenarios – for different reasons (e.g., non-existent numbers, moved numbers, user not present) incoming calls are terminated by the interception of a call or call-pick-up services.
Multiparty services - Conference services - enabling voice connections between several users - the most frequently used is a three- party conference. - The meet-me conference - resembles a chat room, where people can chat online for a certain period of time. The users can join the conference by dialing a special conference number.
Inter-carrier connectivity - traffic distribution is the routing of traffic among several carriers based on the incoming traffic volume. It enables the equalization of incoming and outgoing voice traffic between carriers. - least-cost routing is adopted inside a SI3000 CS and provides a cost-efficient trade and exchange of voice traffic between telecom operators. It is based on temporary inter-carrier price information provided from external systems.
Services for placing or receiving calls in compliance with various criteria. The basic outgoing-call barring is based on the dialed number. Some user groups are permitted to place calls to, e.g., local, city, inter-city, international or special numbers.
Teleworking services A logically logged user can be authorized to access services from any phone at any remote location – regardless of the type of connection, including POTS, mobile, etc.
Alarm and notification call services - simple alarm calls are used as reminders with different frequencies: as single, daily periodic (with repetition number) or on chosen days of the week. - complex notification calls enable a more efficient response in the case of an emergency. They are used as wake-up calls, high-priority calls, alarm calls in the case of a catastrophe, etc.
Hosted PBX service Hosted PBX is a private-network service offered by a public service provider. Iskratel Hosted PBX services bring headquarters, branch offices, remote sites and telecommuters together into a single dial plan. Hosted PBX subscribers connected to different SI3000 MSCNs are included in a wide business group. Business groups can extend over a wide geographical area (this is known as wide-area Centrex) and their members have all the advantages offered to hosted PBX subscribers – private numbering, transparency of services on the network, and group internal charging.
- call-charging information is promptly delivered to subscribers on all port types. Integrated applications offer billing or cost supervision for an individual subscriber or a group of subscribers for a specified time period. - to prepaid users, the services are only available until the amount paid on the prepaid account has been used up (even during a call).
Call-offering services, Multiparty services, Inter-carrier connectivity, Charg
Regulatory services Lawful Interception – The Iskratel’s SI3000 products support ETSI-LI/SORM requirements to make it easy to apply the lawful interception of voice and other telecommunications services by local or distant network subscribers that are processed in call servers monitored by the ETSI-LI/SORM system. Number Portability – based on ITU-T standards and includes several different types of service: - service-provider portability – provides end-users with the possibility of keeping their existing telephone (E.164) number when moving to an alternative service provider. - location portability – provides the end-user with the existing E.164 number when moving to another geographic location within the existing service-provider network. - service portability – provides the end-user with the possibility of keeping their existing E.164 number when changing the type of telecommunications service (e.g., POTS into ISDN, GSM or IP).
Carrier pre-selection – Different carriers provide different types of services, for instance, local, national, international or value-added specialized services. To allow the subscribers of one carrier to reach the services of other carriers, new types of routing are implemented in the SI3000 MSCN solution: - static routing is based on an agreement between the subscriber and the local carrier about how subscribers’ originating calls will be routed (e.g., via which national or international operator) by the carrier. - dynamic routing allows subscribers to select one of many alternative operators for each outgoing call separately with a dialing carrier access code (CAC). - the combination of both principles is also available.

This powerful combination provides a cost-effective solution for carriers, system integrators and application developers seeking to develop carrier-ready, scalable, IP-based enhanced services that can be accessed from both PSTNs and IP networks.
THINK BIG, BUT TAKE SMALL STEPS.
SI3000 SMG key features Media Gateway The media-gateway functionality ensures that the PSTN channel content is converted into a stream of data packets by using various VoIP codecs (e.g., G.711, G723.1, G.726, G729 and Clear Channel) and vice versa. Additional roles in the network: - Transcoding, compression and announcements, - Automatic fax and modem signal detection, - Echo cancellations (according to ITU-T G.168 recommendations), - Voice detection and silence suppression, - Comfort-noise generation (CNG), - Conference calling, - Tone detection/generation over TD (E1) and packet (Gigabit Ethernet) interfaces, - Quality of Service (QoS) built-in mechanisms (replacing lost VoIP packets (PLC), jitter buffer, elimination of variable delays, etc.) for toll-quality voice services.
Signaling gateway The signaling gateway provides the transformation of legacy TDM signaling (SSN7, DSS1 and V5.2) into IP-based session-control protocols (M2UA, M3UA, M2PA, IUA and V5UA) for communication with the call server. This eliminates the need for the operator to adopt the complex SSN7 signaling on the TDM side. In particular, the CAS signaling conversion to the IP network brings the carrier all the existing, well known capabilities.
Media Server The Media Server (MS) bundles the offer for the carrier with the following services: - it connects subscribers to a conference call, regardless of the network type (IP and TDM), - it enables DTMF detection and generation, - it provides voice announcements, interactive voice responses, speech recognition and voice messaging with the interpretation of VoiceXML scenarios (also in combination with Automated Speech Recognition (ASR) and Text to Speech (TTS) conversion servers). The media server performs the indicated functionalities independently of the mode of coding for the voice signal in a call.
Benefits viable means to “squeeze” additional IP revenues from the legacy network; eliminates the need for a separate media server or application server for simple applications; easy and cost-effective extension of IP-based services to legacy users; integrated signaling and media-gateway functionality with a media server on a single carrier-grade platform.

This highly scalable product with a unique combination of technologies for media and signaling processing provides a signaling transfer point, a media server and gateway functions. The signaling transfer point provides connectivity for a wide range of existing installations on SSN7, ISDN, CAS and V5.2. It is controlled by the call server. In the role of a media server it provides the VoiceXML interpretation function and services such as tone generation, tone recognition, announcements and conferences for both types of networks, IP and TDM.
HARDWARE PLATFORMS The AdvancedTCA (ATCA) hardware platform is designed to fulfill the requirements of next-generation carrier-grade communications equipment. The SI3000 MSCN components, except for the SMG, run on an ATCA-compliant computer. SMG servers are inserted into the MEA platform at the high-end central-office or at any other location.
The ATCA-based SI3000 MSCN is convenient for high-end central-office locations and for service provision in densely populated urban areas. A single ATCA housing ensures the cost-effective installation of additional server blades in a single frame.
MEA is the ETSI standardized platform. The MEA platform is Iskratelâ€™s cost-effective hardware-deployment option, designed for metro, suburban and rural networks. It is also suitable for installation at large enterprises. The blade concept of the SI3000 MSCN components allows the scalability of the NGN solution. It can be easily reconfigured from a compact architecture to a distributed architecture for larger configurations.

No two carriers are likely to follow identical paths in establishing a pure IMS architecture. However, with the SI3000 MSCN, each carrier has the possibility to adopt a telecommunications infrastructure meet its current needs and its planned development strategy.

Network-element transformation – Regardless of the access part of the future IMS, the IMS core will evolve from the SI3000 MSCN product line. The
Packet-based (SIP) subscribers inherently use these services, but existing POTS and ISDN subscribers are insufficiently covered. The AGCF functionality provided by the SI3000 MSCN product line is the solution for this issue. The AGCF functionality hides all the specifics of the existing PSTN towards the IMS core. All the existing PSTN subscribers, based on the subscription option, are seen as packet-based (SIP) subscribers from the IMS core, and they are able to consume additional packet-based services.
The Evolution - The goal of the process is to achieve the adoption of the newly offered services by the end-users regardless of the installed access technology.
The migration towards IMS requires network-element adoption in the service delivery, core and access parts of the network.
Seamless migration towards IMS with the SI3000 MSCN
Iskratel’s approach to network evolution is based on the gradual migration of the existing PSTN infrastructure towards the IMS-oriented architecture. The migration scenario is suitable for existing telcos and for competitive newcomers, deploying fully IPenabled networks. Iskratel’s most important future role is to control and manage telecommunications and new web-based services from the fixed and mobile worlds through a single user profile at a single point.
Existing service support - Voice services - Self-provisioning - Video&Gameon-demand
Service creation and deployment
- Personalized advertising - Location-based services - Web 2.0 (communitygenerated content/ services) - Personalized content
- Single user profile - Single bill for bundle of services - Personalization of services (location aware)
flexible SI3000 CS is transforming to be able to provide the functions of P/I/S-CSCF, BGCF, IWF, MRFC and MGCF/AGCF network entities. The SI3000 SMG provides the following IMS functions - SGF, T-MGF and MRFP. The SI3000 AS (unified communicator – IMS client) is evolving into a pure IMS-compliant SDP. The desired goal – Finally, the “pure” IMS environment is going to give the carrier the opportunity to achieve its desired goals: a single environment for developing new services, to provide the subscriber with a single profile, managed by a single network element (HSS - Home Subscriber Server). The subscriber is going to have a single, location agnostic identity, and will receive a single bill for the whole bundle of services.
