Wireless E911 emergency calls use VoLTE and IMS networks, which will require new test platforms.

Wireless E911 emergency calls use VoLTE and IMS networks, which will require new test platforms.

To support emergency services for VoLTE subscribers, many new items must be considered from a device and network perspective. The transition from a traditional circuit-switched (CS) network to an all-IP-based network utilizing IMS for voice calls, and the addition of new positioning methods like A-GNSS, OTDOA, and eCID with a new information exchange protocol (LTE Positioning Protocol), all add new dimensions to this mandatory feature. In fact, vendors must now ensure this feature via functional and performance compliance of their devices in a multi-technology environment. As a result, it’s important to emulate and test all aspects of the mobile access and IMS network for efficient VoLTE E911 over IMS.
