Functionality of MVTS II

MERA VoIP Transit Softswitch II (MVTS II) is a next-generation prepaid switching platform with a geographically distributed architecture and highly flexible traffic handling capability. MVTS II is specifically designed to increase the efficiency of VoIP traffic management on large-scale networks and is targeted towards carriers running 3+ million minutes of VoIP calls per month. Built on modular architecture, the versatile MERA solution alleviates the challenges of managing traffic flows on highly distributed networks by providing intelligent built-in algorithms of call routing and elaborate analysis and reporting tools. MVTS II is a handy solution for wholesale carriers who consider price-to-quality ratio in each call route and need to promptly react to changes in routing policy of their peers. MVTS II is intended for carriers that would like to keep all billing and routing data in one single database (powered by Oracle), included into the system. MVTS II is ideal for carriers that would like to take advantage “hosted softswitch” capability and sacrifice ease of the system management for elaborate functionality.

The rich feature set of the MERA solution includes:

Enhanced routing capabilities

MVTS II intelligent routing capabilities enable carriers to choose the most appealing routes, maximize ASR and service availability and implement flexible routing policies.

MERA VoIP Transit Softswitch II provides elaborate mechanisms which perform smart 'look-ahead' routing based on:

Carriers can create customer-specific routing groups to perform route hunting within a predefined group of dialpeers which enhances routing efficiency and protects the network against fraud.

To maximize ASR and service availability carriers can create equipment groups based on equipment location. If one device within a group is physically unavailable — due to a blackout, for instance — other devices will most probably be down as well. In such cases MVTS II discontinues further search of routing options within the group and passes on to another equipment group to minimize latency.

Profitability monitoring

Computer-aided profitability monitoring significantly simplifies network administration tasks. The network administrator has to set the profitability threshold and whenever profitability of a certain destination drops, the system will send him an alert to email. Based on the administrator's choice, MVTS II will either block the unprofitable destination or display a message informing the operator that the route profitability has degraded beyond the preset level. The operator can opt to either block the path or allow its use to a limited group of clients.

Flexible Proxy Options

MVTS II provides various proxy options which allow carriers to increase the system's throughput while maintaining a high level of network security. MVTS II features native support of SIP and H.323, transcoding, protocol normalization and two-way H.323/SIP translation to solve interoperability issues and bridge between multiple-vendor equipment incorporated in home or partner network.

To optimise bandwidth consumption and keep up critical security levels, MVTS II provides flexible proxy options. The system can run both in Full Proxy and Signaling Proxy modes with the desired proxy mode selected on a case-by-case basis. MVTS II enables the carrier to assign the needed proxy mode to each separate gateway.

Load balancing

MVTS II offers centralized load distribution mechanism which adds to better fault-tolerance, more efficient use of the system's resources and enhanced scalability. MVTS II performs license-dependant dynamic load balancing that assures distribution of traffic between servers according to their current workload. MVTS II offers geographic license distribution mechanism which enables carriers to allocate the unengaged license share to the busiest PoPs eliminating equipment downtime.

Analysis and reporting tools

MVTS II offers a full-fledged management system that enables carriers to keep the finger on the pulse of the network and control its efficiency. MVTS II provides a vast choice of analytical capabilities to enable real-time monitoring of call dynamics based on time of the day, day of the week, QoS fluctuations, load, profitability and other parameters. The resulting estimates are visualized in various intuitive charts and graphs. With the network analysis engine, the system can automatically choose the most profitable tariff plan for a destination, based on the prices and average call duration to enable the carrier to select the best business partner in each particular case. MVTS II supports real-time alerting (rate plan unprofitable alert, low profit alert, routing path restriction alert, call looping alert etc.) to facilitate constant network profitability monitoring.

Pre-billing and accounting capabilities

MVTS II features support of RADIUS AAA for inferaction with add-on billing systems.

The MERA solution allows import of partner rate plans and customer accounts and export of CDRs for external billing systems. Ability to import partner tariff plans significantly reduces the dial plan preparation time thereby enabling the carrier to flexibly and promptly respond to the pricing whims of peering partners. MVTS II pre-billing and accounting capabilities enable carriers to implement flexible discount management and support of various billing increments. All the data is stored in the system's Oracle™-powered database which features its own redundancy scheme.

Partitioning

Partitioning capabilities allow carriers to explore new business models and drive in new revenue streams by attracting start-up operators looking for low cost entry into the VoIP wholesale market. Carriers can create multi-layer partition groups with granular access control and different user privileges. MVTS II offers web layout customization for each partition holder.

Number portability support

Number portability allows carriers to terminate both mobile and landline traffic to the network of the carrier the subscriber is currently assigned with regardless of the number prefix.This provides a significant reduction in termination costs owing to lower home-net termination prices offered by operators. High call processing speed minimizes latency, optimises consumption of network resources and enhances the system's performance.

ETSI LI standard compatibility

The MERA ETSI LI Mediation Device (MMD) makes the MVTS II  softswitch ETSI compliant in LI effort.

The MMD is a converter device that ensures interaction between MVTS II and the Law Enforcement Monitoring Facility (LEMF) during lawful interception.

The MMD functions include:

MMD specifications:

1. Supported standards:

2. LEA-Provider interoperation is enabled by the following interfaces:

3. MMD can operate with 100 MVTS II systems and up to 10 LEA Monitoring Centers simultaneously
