Patent Searching and Data


Title:
EMPIRICAL DATA BASED 5G NETWORK SEARCH FOR PERFORMING 5G NETWORK RESELECTION FROM A LEGACY NETWORK
Document Type and Number:
WIPO Patent Application WO/2021/232374
Kind Code:
A1
Abstract:
This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for selecting a periodic search time interval associated with a 5G cell search. In some aspects, a user equipment (UE) that is registered with a legacy cell associated with a wireless wide area network (WWAN) legacy radio access technology (RAT) may determine whether the UE previously found a 5G cell while registered with the legacy cell. The UE may determine whether the UE previously found a 5G cell while registered with the legacy cell based on whether the legacy cell is listed in a 5G cell available list or a 5G cell not available list. The UE may select a periodic search time interval for the 5G cell search process based on whether the legacy cell is listed in a 5G cell available list or a 5G cell not available list.
