AI Technical Summary

Technical Problem

The existing Cat1 module can only support VoIP or IMS calls. IMS calls are expensive and consume a lot of power, so it is impossible to achieve real-time telephone functionality through IMS.

Method used

By parsing call signaling through the call capability platform, virtual IMS accounts and actual IMS accounts can be obtained and associated. The call signaling can be forwarded in the core network or Internet using IoT traffic cards, supporting VoIP and IMS dual-domain calls.

Benefits of technology

The Cat1 module supports VoIP and IMS dual-domain calling at low cost and low power consumption, thus improving communication capabilities.

Abstract

This invention provides a calling method and system for Cat1 modules. The method includes: receiving call signaling sent by the Cat1 module via a call SDK through a call capability platform; parsing the user's virtual IMS account from the call signaling; and having a built-in IoT data SIM card in the Cat1 module. If the user's configured call policy prioritizes IMS calls, the method obtains the actual IMS account corresponding to the user's virtual IMS account and forwards the call signaling to the peer via the core network based on the user's actual IMS account. If the user's configured call policy prioritizes VoIP calls, the method obtains the virtual IMS account corresponding to the peer's actual IMS account and forwards the call signaling to the peer via the Internet based on both the user's virtual IMS account and the peer's virtual IMS account. This invention enables Cat1 modules to support VoIP and IMS dual-domain calling at low cost and low power consumption.
