Page #Key Message:As the basic LTE voice solution, one of CSFBs main challenges is connection latency. Ultra-Flash CSFB exchanges information between the EPC and the CS network while mobile phone fallback to UMTS network and CS core network can do the preparation in advance by private SRVCC procedure. The connection latency of Ultra-Flash CSFB can be shorten for about 1 sec.
Note:The standard SRVCC procedure will judge 2 conditions: 1) VoIP setup; 2) IMS service is OK. The private protocol process these two judgment specially by Huawei MME & MSC equipment.SRVCC UE is neededThe time delay of traditional PS HO CSFB is about 5s.SRAN7.0 Flash CSFB feature is used in L2U redirection scenario.23
