Next generation mobile network latency triggered mobility
A base station determines a latency requirement of a user equipment device (UE), and receives latency measurements associated with multiple neighboring cells or cell sectors having coverage areas within a certain proximity to the base station. The base station measures a latency associated with a first cell or cell sector, having a coverage area generated by the base station, that is currently serving the UE. The base station triggers a mobility event for the UE, based on the UE's latency requirement, the measured latency of the first cell or cell sector, and the latency measurements associated with the multiple neighboring cells or cell sectors, to a selected one of the multiple neighboring cells or cell sectors.
