Protei IP Multimedia Subsystem (IMS) is a system consisting of virtual network functions. IMS delivers rich real-time communication services for both consumer and business users over any access network, for any device type, including smartphones, tablets, wearables, laptops, and fixed-line phones. Examples of communication services include HD voice (VoLTE and 5G voice), Wi-Fi calling, enriched messaging, enriched calling with pre-call info, video calling, HD video conferencing, and web communication. Protei IMS networks are deployed globally.
PROTEI IMS solution prioritize high-quality voice and video calls, offering excellent audio quality, low latency, and exceptional reliability. High-speed data transmission can also be utilized while on a call. Although deploying the IMS Core may require significant investment in the initial phase, the NFV technology implemented in PROTEI IMS Core allows for the use of existing resources to launch small vIMS systems with minimal costs and resources from the operator. This solution is fully compliant with 3GPP International Specifications, including TS 23.228, TS 23.218, TS 23.229, TS 24.229, TS 29.228, TS 29.229, and TS 29.949.

Simultaneous voice and data, effective migration to all-IP
PROTEI EIR enables network operators to enter the IMEI of stolen handsets into a “blacklist”, thus preventing them from being registered on the network.
PROTEI EIR provides automatic device detection functionality required for identification of changes of subscriber’s device. Every change of subscriber’s device will be detected by PROTEI EIR. Detection is based on MAP procedures (MAP-CHECK-IMEI) in full accordance with international standards. The change of subscriber’s device leads to the change IMEI-connected with MSISDN by comparison received IMEI with saved one. PROTEI EIR can detect changes calling the notice of external system. PROTEI EIR is based on PROTEI xVLR solution that is “umbrella” platform providing the ability to process, store and transmit to the external applications location information regarding subscribers of mobile networks, switching elements may transfer. The platform is able to process information that is available through core network vendors’ proprietary features or using standard MAP capabilities. Collected data may be efficiently used for such services as geographically targeted SMS campaigns, loyalty services and many others.
