3G to 4G Migration


AGNITY 3G to 4G Network Migration Solutions:


  • Communications Application server (CAS) – a virtualized, standards based converged Service Delivery Platform that works across 3G, 4G LTE, WiFi and VoIP. It bridges legacy and next generation networks either via its Service Broker functionality or by deploying in a Hybrid Configuration, a patent pending solution (commercially deployed) for ensuring complete feature parity for subscribers across any access network.
  • Next Generation IN (NGIN) Services – applications, including network based VPN, Number Portability, Advanced Call Routing (ATF) / IVR, Prepaid and Online Charging System, to allow replacement of existing legacy IN features as the current platforms reach EOL or fail to support next generation interfaces.
  • Migration Tools and Methodologies – extensive tools, capabilities and experience to achieve the goal of parity between new systems and legacy systems with minimal impact to network operations.

When will the migration from 3G to 4G happen?

3G to 4G migration is currently in full effect, and will only continue. Out of the 500 network providers worldwide, 400 have already started the migration. 4G networks use different radio frequencies to transmit data than 3G, and with use of these transmit signals costing billions of dollars, the move away from 3G and onto 4G is an vital and inevitable one for network service providers. Many carriers are announcing their plans to discontinue their legacy networks, and managers of corporate wireless networks must prepare for the network migration from legacy 2G and 3G networks to the increased data speeds and longevity of the 4G LTE network. Even with networks making the progressive move to a new generation of 4G technology, 3G networks cannot be shut down for years to come. For IN apps on the 3G network, a solution must be in place to move these apps and voice traffic over to the 4G network. AGNITY supports both 3G and 4G networks on a platform, which provides a seamless network solution that can allow the migration to happen at a network service provider’s pace, and will set the company up for future technologies.

Capabilities of a 4G LTE Network

4G networks bring capabilities that 3G lacked, such as streaming large amounts of data via video services and WebRTC. The advanced data services that 4G provides enables the consumer’s to perform tasks as efficiently on a smart device as was they would connected to broadband in their home or office. As a whole, 4G makes functioning on a smart device more efficient, and allows hefty media to accessed quickly. 4G LTE technology benefits network operators by allowing them be able to do more with less, and allows carriers to support more customers and devices while maintaining fewer towers. The unmatched download and upload speeds of 4G LTE have companies viewing this network generation as their key platform for the next decade.

The move from 3G to 4G LTE.

Telecom Service Providers are in the midst of massive network transformations, upgrading their networks from TDM/3G mobile to IMS/LTE. One of the key features of these next generation networks is the ability to separate the Applications from the underlying access method. Service Providers are becoming more application-centric as they migrate existing services and look for new services to leverage the tremendous capabilities of their new networks and devices.

AGNITY’s Communication Application Server (CAS) plays a key role in the separation of Application Logic from the underlying Access Networks. CAS is a SIP-centric, high-performance, carrier grade, and fault-tolerant software platform built on open standards, supporting many network protocol interfaces (SS7, IP, IMS and LTE). It supports multiple applications on a single platform and, with its routing rule engine, is capable of sophisticated application triggering and the interworking of multiple applications (both on the CAS platform and elsewhere in the core network) for any individual call. CAS helps service providers to migrate existing IN applications (either by replacement) or via a Service Broker functionality and it allows the deployment of a full suite of existing AGNITY applications.
