3GPP protocol certification follows PTCRB test case
Mobile device and handset manufacturers will soon be able to certify that their products conform to the 3GPP protocols for ‘emergency services calls over IMS’ with the introduction by Anritsu of the first PTCRB-approved test case. The test and measurement company has added the new protocol test cases for IMS (IP Multimedia Sub-system) emergency services calls to the suite of test cases supported on the widely used ME7834L Protocol Conformance Test (PCT) system. It provides users of the PCT system with officially approved protocol test cases.
Conformance with the IMS emergency services protocol is set to become an important requirement for handsets running on LTE and LTE-Advanced cellular networks in the US and elsewhere.
Voice calls on these IP-based networks are normally routed via an IMS architecture as a Voice-over-LTE (VoLTE) service. As IMS-based voice service begins to gain more widespread adoption, it has become an essential requirement of public safety that IMS technology should reliably support calls to emergency services such as the police and ambulance services, as 2G and 3G network technologies already do.
Members of the public will clearly want to know that they can rely on this new technology in case of emergency calls, and will put much faith into operators and handset suppliers that sufficient testing of the emergency service calls has been made.
