Telecom Application Server

Agile and innovative communication services for voice networks

Nokia TAS and a cloud-native programmable core will give operators the business agility they need to ensure sustainable business in a rapidly changing world and let them gain from the increased demand for high performance connectivity.

What is Telecom Application Server?

Nokia TAS is a Telecom Application Server in voice networks, built according to IMS core architecture, which provides a superset of services for VoLTE, Voice over WiFi (VoWiFi), Voice over 5G (Vo5G) and fixed-access networks.

Simplifying Voice Network Operations with Nokia TAS

Nokia TAS provides feature parity with mobile Circuit Switched (CS) voice and VoLTE, Vo5G and supports an IMS centralized service. It forms part of Nokia’s virtualization, providing strong Core synergies with other Nokia core elements.

With Nokia TAS, operators can re-use existing back-end systems such as billing, IN and SMSC for VoIP and VoLTE. The same OSS can be used for both VoLTE, Vo5G and CS voice, making TAS integration remarkably easy.

Features of Telecom Application Server

Agile service creation

Fully featured application development capabilities. With open (REST-based) API’s and integrated Java Execution Environment, Nokia TAS allows operators to customize and create their own services and developers to create voice call related applications.

Cloud optimized

Nokia TAS shares the strategy of using open interfaces towards external peers or layers, such as Virtual Network Function Management, Network Function Virtualization infrastructure, and operation and management.

Programmable services environment

Nokia TAS provides a programmable services environment that can be used for voice, messaging and video sessions for SIP subscribers to LTE, 5G and other broadband access methods. Exploit TAS programmability within immersive services using Voice over New Radio (VoNR).
