Problems solved by technology

[0003] However, when VOLTE terminals use the GSM network for international roaming, they need CDMA HLR to allocate numbers, voice calls need GMSC routing, and SMS services must go through the CDMA signaling network. The long-term existence of C2G international roaming will lead to dependence on CDMA network equipment, and CDMA cannot be implemented. The withdrawal of the network is not conducive to the subsequent development of the network

Abstract

The disclosure provides a method for realizing VOLTE terminal international roaming service, a dual-mode gateway, a communication system and a storage medium, and relates to the field of communication technology, wherein the method includes: setting the HLR module and the S-CSCF module of the dual-mode gateway; wherein, HIR The module performs the HLR function of the GSM network, and the S-CSCF module performs the S-CSCF function of the IMS network; through the data interaction between the HIR module and the S-CSCF module, it is used to complete the international roaming registration for the VOLTE terminal outside the country, and to use the VOLTE terminal as a The called call is routed. The disclosed method, dual-mode gateway, communication system, and storage medium can reduce hardware costs, and at the same time make the message path for international roaming shorter, safer, and more stable; even if CDMA withdraws from the network, VoLTE and GSM dual-mode users can realize international roaming. Roaming to meet the needs of international operations.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular to a method for realizing international roaming service of a VOLTE terminal, a dual-mode gateway, a communication system and a storage medium. Background technique [0002] At present, my country's CDMA (Code Division Multiple Access, Code Division Multiple Access) network and the domestic No. 7 signaling network are about to withdraw from the network, and China Telecom is mainly promoting VOLTE (Voice over Long-Term Evolution, long-term evolution voice bearer) terminals without C-mode , considering the problem of international roaming from VOLTE terminals to areas without VOLTE networks, it is necessary to use VOLTE terminals with GSM (Global System for Mobile Communication) mode to realize international roaming through the GSM network. [0003] However, when VOLTE terminals use the GSM network for international roaming, they need CDMA HLR to allocate numbers, voi...
