USSD over IMS Gateway
Canvas® USSD over IMS Gateway (USSI GW) is a next generation USSD over IMS gateway for service providers, MVNO’s and wireless operators to offer USSD-based applications and services seamlessly to both GSM (2G/2G) and LTE (4G) subscribers.
Users still wants to benefit of speed and interactivity characteristics of USSD communication to manage their legacy services as well as new generation LTE services even they attach to LTE network. CSFB method, which is used for this purpose, is not an efficient and preferred method, since it causes discomfort for users due to latency, fall to decreased (2G/3G) data throughput levels, etc. Canvas USSI Gateway eliminates all Circuit Switched Fallback (CSFB) problems due to lack of USSD support in LTE networks and provides seamless service continuity.
Canvas USSI Gateway enables subscribers to access USSD services such as balance enquiry, various service configurations, etc., directly from attached LTE/IMS network and provides similar user experience for USSD based services which they are having in 2G/3G networks.
