AI Technical Summary
When the gNB receives the IMS voice service quality flow and triggers EPS fallback, insufficient measurement time or lack of inter-RAT measurement configuration leads to missing inter-system measurement results, resulting in excessively long EPS Fallback latency and affecting the 5G call experience.
The terminal acquires the measurement configuration information of the access network in the idle or inactive state, and performs measurements when it receives a paging or the conditions for establishing an RRC are met. This includes acquiring frequency point information, measuring cell list, RSRP/RSRQ/SINR, etc., to ensure that the measurement is completed before the RRC connection is established.
By reducing EPS fallback latency through early measurement, the user experience during 5G calls is improved.
