VoLTE和CS语音补充业务一致性方案研究

Research on CS and VoLTE Supplementary Service Consistency Solution

针对VoLTE的IMS MMTel业务和传统CS域补充业务共存场景,总结了3GPP以及其他几种CS/IMS公共语音SS业务数据同步方案,并对各方案的前景和适用性作了分析。这些方案使得用户在IMS域和CS域具有一致的补充业务体验。

For the scenario that IMS MMTel service in VoLTE co-exists with CS supplementary services, it summarizes several solutions to keep CS/IMS common SS data synchronization. Simultaneously, the prospects of the various solutions and their applicability are also presented. These methods can make user experience consistent for CS/IMS common supplementary services.
