Network products and solutions for smarter signaling and core network operations

Simplify signaling across network generations

Managing signaling across multiple network generations can become complex as traffic moves from legacy to modern networks. Tieto Evolved Signaling Controller (ESC) provides a single solution for signaling control and routing across 2G, 3G, 4G and 5G networks.

ESC combines functionality traditionally handled by separate STP, SRP, SGW, DRA and DEA solutions. This allows operators to reuse capacity as traffic shifts between network generations. Built-in signaling firewall functionality protects SS7/SIGTRAN and Diameter traffic from security threats.

The cloud-ready, platform-agnostic solution supports virtualized and containerized environments. ESC also provides extensive optional features, including dedicated capabilities for SMS handling.

Reduce roaming costs while maintaining service quality

Managing outbound roaming means balancing cost with the coverage, quality and services subscribers expect when travelling. Tieto Steering of Roaming gives operators real-time control over which roaming networks their subscribers use across 2G, 3G and 4G networks.

The solution automatically directs subscribers to preferred roaming partners based on configurable rules and roaming agreements. Operators can optimize network selection by factors such as location, time and traffic share, or blacklist unwanted roaming networks. This helps reduce roaming costs while directing subscribers to partners that provide the required coverage, quality and features.

The scalable solution supports containerized, virtual and bare-metal environments and provides a web interface and REST API for configuration, provisioning and operations.

Protect core networks and subscribers from signaling threats

Telecom core networks face security threats that can disrupt network operations and target operators or their subscribers. Our firewall solutions protect SS7, Diameter and SMS traffic across 2G, 3G and 4G networks.

The signaling firewalls protect core networks against attacks such as network overload and denial of service, while the SMS firewall helps protect subscribers from SMS fraud, spoofing, flooding and spam. Built-in firewall rules follow recommendations and specifications including GSMA FS.11, FS.19, IR.70 and IR.71, and 3GPP TS 23.840.

Operators can adapt and expand filtering rules as new types of attacks emerge. The solution supports containerized and virtualized environments, with a web interface and REST API for configuration and operations.

Protect networks and revenues from unauthorized devices

Stolen and unauthorized devices can create security and revenue risks for operators, while EIR capabilities are also required by regulators in many countries. Tieto Equipment Identity Register (EIR) helps operators control which devices can access their networks across 2G, 3G, 4G and 5G.

The solution supports blacklists, whitelists and greylists, with built-in integration to the GSMA blacklist database. Operators can also associate devices with specific subscriptions or groups of subscriptions, providing additional control over how identified devices are allowed to operate on the network.

A single EIR installation supports multiple network generations simultaneously, with capacity that can be reused across network types. REST APIs support provisioning and operations, with CSV files available for bulk provisioning.

Simplify number portability across networks

Providing number portability across multiple network types requires operators to manage different technologies while enabling subscribers to keep their phone numbers when changing operators. Tieto Mobile Number Portability (MNP) provides a unified solution and number portability database across mobile and fixed networks.

The solution supports 2G, 3G, 4G and 5G, as well as SMS, VoLTE, Vo5G and IMS-based networks. A common database serves different network types, helping simplify operations and allowing capacity to be reused as networks evolve.

Operators can use the built-in number portability database or integrate an existing external database through LDAP. REST APIs support provisioning and integration with external operation and management applications, with CSV files available for bulk provisioning.

Detect and configure devices across mobile networks

Identifying devices as they enter the network enables operators to support device management and equipment register applications. Tieto Device Detection Application (DDA) automatically detects new devices through IMSI Attach or location updates, providing the device information needed for automatic configuration through device management applications.

DDA supports 2G, 3G and 4G LTE networks simultaneously and provides the IMSI, IMEI and MSISDN of detected devices through APIs that reduce signaling complexity and support faster integration and application development.

The solution can integrate with an existing EIR or provide EIR functionality where one is not deployed. It can also support applications such as welcome SMS services and is available for virtualized and containerized environments.

Enable reliable connectivity to signaling networks

System integrators, application developers and network operators need signaling connectivity to build and operate telecom applications. Tieto Signaling Software provides access to SS7, SIP and Diameter signaling networks in Linux environments, with APIs for a wide range of signaling protocols.

The software supports scalable and redundant deployments, with traffic automatically distributed across available cores. Capacity can be expanded by adding stack instances, including at runtime without bringing the entire system down. A floating capacity license allows capacity to be reallocated between SS7 and Diameter.

The solution runs in bare-metal, virtualized and containerized environments, including Kubernetes and Red Hat OpenShift, with tools for configuration, statistics and alarm monitoring.

Deploy network functions across modern telecom infrastructure

As telecom networks and infrastructure evolve, operators need network functions that can be deployed and scaled across modern environments. We provide a portfolio of network functions designed for virtualized and cloud-native infrastructure, supporting control plane services across 2G, 3G, 4G and 5G networks.

The portfolio includes EIR and Central EIR, MNP, IP Short Message Gateway, SMS-C, IN-GW and USSI-GW, supporting use cases from device management and number portability to messaging and migration of USSD applications to IMS networks.

Network functions can be deployed as multiple instances distributed across hardware and software platforms, supporting scalable and redundant deployments.

Expert support for deployment and ongoing operations

Deploying network products requires specialist expertise across installation, configuration, integration and testing. Our professional services support product deployment projects through to acceptance testing and traffic migration from adjacent nodes.

Beyond deployment, we help operators maintain and develop their network environments with product reconfigurations, updates and upgrades, optimization, network audits and health checks, network design and planning, and tailored training.

Our distributed care team provides 24/7 maintenance and support, with access to experienced engineers for monitoring, troubleshooting and issue resolution.
