SOLUTIONS FOR VOLTE

Voice over LTE (VoLTE) enables 4G LTE operators to offer rich voice, video and messaging services. Our products enable smooth transition to a VoLTE based network and rapid delivery of VoLTE services.


Benefits

The deployment of Squire Technologies products and utilisation of our specialist signalling services will deliver the following immediate benefits in a VoLTE network:

  • Optimal use of radio bandwidth delivering substantial cost savings

  • Voice quality assurance

  • Rapid support for multi vendor VoLTE handsets

  • Enable multi device, single number services

  • Enable Rich Communication Services RCS(e) to SMS inter-op

  • Enable seamless 4G to traditional VoIP / 2G / 3G / PSTN interconnect

  • Ongoing support for rollout of new and innovative VoLTE services

How?

At the signalling core of a VoLTE network is our SVI-SBC Session Border Controller product. The SVI-SBC is able to act as both a proxy and a B2BUA allowing it to dynamically manage signalling and media traffic that needs translating in the core of the network whilst proxying the remaining traffic. With half a decade of international carrier grade deployment the SVI-SBC can guarantee optimised signalling interconnect in a VoLTE network delivering:

  • Support for VoLTE Pre-Conditions
    - Manage end-to-end bandwidth with support for VoLTE pre-conditions
    - Insure Voice Quality
    - Rapidly deploy new VoLTE handsets and manage interconnect issues from handset OS upgrades

  • Support for multi device, single number services
    - Manage multiple subscriber registration for softphone app’s across multiple devices – tablets, laptops, mobiles
    - Manage subscriber forking on calls across multiple devices on multiple networks
    - Retain a single number per subscriber

  • Support for signalling and media inter-op with traditional VoIP devices and App enabled softphones
    - SIP signalling inter-op and media transcoding between AMR, AMR-WB, Opus and G711, G729 and G723 *for full list of codec support please see here*

IP Short Message Gateway

At the heart of the problem is that 2G/3G networks are built upon legacy SS7 protocol technology, whereas 4G LTE networks are developed around the Diameter protocol.

What is required is a bridge between these technologies, one that will seamlessly allow the sharing of policy, charging and authentication information.

VoLTE Media Gateways

Squire Technologies carrier grade Media Gateways (SVI_MG) and Media Gateway Control Function (SVI_MGCF) provide a seamless breakout to the PSTN. Coupled with Squire Technologies specialist installation and commissioning services insures a comprehensive delivery of the VoLTE Breakout Gateway Control Function (BGCF).
