The demand for data services anytime, anywhere with high quality of service has made requirements for an optimized PS Core Network imperative. Hence, it is important that the design, planning of PS Core Network has to be pristine. Vittotel Technologies have tried and tested artefacts for the Design, planning and Optimization for Packet Switched Core Network.

For operators to continue to maintain healthy bottom line in the reality of increased subscriber base and demand for specialized services, another solution for operators is Multi Operator Core Network or MOCN.

MOCN is different MNOs sharing the Radio Access Network but still maintaining their individual Core Network. The advantage of this solution is improved coverage and capacity, CAPEX and OPEX efficiency for all participating operators because these costs are spread between them.

Vittotel Technologies is able to provide end to end Design and implementation for this solution.

Vittotel Technologies provides end to end Design and implementation for Mobile Number Portability (MNP). HLR/FNR, NGIN (SCP) Design.

Vittotel Technologies provides end to end Design and implementation Transmission Networks E.g. VSAT, Terrestrial Microwave Network and Wireless LAN (Wi-Fi)

The ever increasing data traffic as a result of greater penetration of smartphones, tablets and “always on” applications they support has put enormous pressure on mobile operators and other service providers signalling network. Meeting the demands of subscriber hence has become a challenge. The pressure is expected to increase with the fast deployment of 4G LTE/EPC networks.

Next Generation Networks such as IMS and LTE which are deployed for data applications deploy DIAMETER as the protocol for signalling. New elements such as policy servers, gateways, session controllers, Subscriber database and charging systems are interconnected through DIAMETER protocol to exchange critical network and services information. Also, DIAMETER signalling capabilities support all subscriber services, both revenue generating and non-revenue generating, thus its criticality to the overall network performance and stability cannot be underestimated. The traffic volume and the complexity of DIAMETER traffic thus place staggering demands on core Signalling elements and serious consideration for its reliability.

For example Gy interface, Online Charging Services (OCS), requires real time operations and heavily rely on DIAMETER protocol causing serious concerns about the reliability of the signalling network.

Vittotel Technologies has the capability to help operators design, implement, manage and optimize their DIAMETER signalling network.

The value added areas are:
• MAP (SS7) to DIAMETER Interworking: It will be possible for Inter System Handover and Roaming between legacy 3G Network and LTE/EPC Network.
• PCRF Binding: This ensures that in multi PCRF node deployment, a PCRF handling a session for a subscriber continues to handle Requests for that subscriber’s session.
• Subscriber Location Functionality: This ensures that in multi HSS node deployment, subscribers are identified and mapped to the appropriate HSS no matter the geographical distribution of the HSS nodes.
• Roaming Steering: This DIAMETER solution will ensure operators are able to select the optimum roaming partner in terms of cost, QoE, QoS. Hence achieve their business objective of efficient CAPEX, OPEX, Customer satisfaction and decreased subscriber churn. Both the operator and user benefit from this feature.
• Topology Hiding: This solution is beneficial for the operator to protect its DIAMETER network against possible malicious attack because of interconnection to other networks.
• Layer 3 Security: This feature provides additional security at Layer 3 to the ones provided within protocols such as SCTP, GTP etc.
• DIAMETER Mediation: This ensures interoperability between providers that operate on different Releases of the DIAMETER protocol.

We also ensure seamless interoperability in multi-vendor DIAMETER nodes environments.

The demand for mobile data bandwidth is rising exponentially. This places the requirement on operators to expand the capacity of the network. This expansion cannot be infinite and there must be a way to ensure operators maintain efficient CAPEX and OPEX whilst ensuring the operator is able to provide the end user a consistent quality of experience.

Vittotel Technologies is able to ensure clients deploy robust Policy and Charging Control in the data network that allows different levels of QoS to different applications. The operator has the capability to create flexible service plans based on transactions, connections, time-of-day, location, applications, or data usage based on DIAMETER protocol.

The areas the PCRF will add value include:
• Machine to Machine: defines policies for different levels of QoS to different machines.
• Roaming: It will be possible to reduce inter-carrier roaming costs by setting roaming notifications and limits to ensure users have best possible QoE through effective management and control of data traffic via the PCRF.
• Differentiated Hierarchical Services: It will be possible to group users for defined QoS based on interest, location, application and configure priorities.
• Real Time Mediation: For pre-pay data application users, the PCRF will reduce latency by identifying the RTM Front End Server for a particular session.
• Personalized Services and Applications: It will be possible for users to have personalized profile so as to restrict services and applications they have access to. This helps users to control their cost as well as have control over access e.g. parental control.

• Deep Packet Inspection: DPI complements the PCRF functionality to enforce rules and charging policies based on application.

• Service Aware Charging and Control

• Data Access Optimisation Support Network. E.g. Reference Databases for access control.
