Being a GCF RTO and Field Trials accredited Test House IoTAS is qualified to conduct IP Multimedia Subsystem (IMS) testing, which is the common service platform for deploying communication services over IP technology (e.g. VoLTE, VoWiFi and RCS).
VoLTE and VoWiFi services are now expected on most smart phones and ‘new-release’ voice/data comms devices. Accordingly manufacturers should be looking to thoroughly test all Voice and WiFi scenarios with LTE communications and IoTAS can provide this service.
An extensive set of tests need to be run by a terminal supporting VoLTE to obtain GCF approval. These tests are specified within GCF-CC Annex F5.2 and the test procedures are detailed in Section 51 of GSMA TS.11 Device Field and Lab Test Guidelines. IoTAS have experienced Engineers in multiple locations and can offer a full GCF F5.2 VoLTE test solution for network-configuration dependent (VoLTE), including all supported SRVCC scenarios, and client-to-client (VoC2C) testing.
Having completed a large number of GCF VoLTE projects, IoTAS have found some aspects of the GCF F5.2 plan could be enhanced, while IoTAS work to do that, IoTAS have developed our own VoLTE solution which goes beyond the requirements of the tests included in the GCF-CC F5.2 by testing additional aspects of VoLTE functionality to ensure better device compliance to GSMA IR.9x documents.
Examples of the areas these additional tests cover are;
* Multiple scenarios not covered in GCF-CC F5.2 are tested
In addition to providing a first class testing solution to device manufacturers, IoTAS work with FTQO Networks. Some of this work is testing hand in hand to find test locations, or to capture logs and confirm undesirable behavior that the network wishes to investigate.
IoTAS also feed back some of our own internal benchmarking test results and observation which provide the network with additional information which can help the network improve its VoLTE deployment and VoLTE knowledge base which aids the industry as a whole.
