Google patents faster cell switching for mobile networks

Patent drawing
Patent drawing from the official filing.

This filing describes a method for mobile networks to switch a phone to a new cell tower more quickly by using a lower-level network command. It aims to reduce the delay and data overhead compared to traditional switching methods that rely on higher-level network layers.

Why it mattersIt could lead to smoother video calls and faster data speeds by reducing the lag when moving between cell towers.

In the filing’s own words

Methods and devices operate within a radio access network to facilitate a fast serving cell change using a lower-layer triggered mobility, LTM, procedure, reducing latency and overhead relative to L3-triggered cell-switching procedures. A wireless communication method ( 900 A) performed by a distributed unit, DU, of a network entity includes receiving ( 904), from a centralized unit, CU, of the network entity, a CU-to-DU message identifying a target cell and directing the distributed unit to prepare an LTM DU configuration for switching a UE from a source cell to the target cell. The wireless communication method further includes transmitting ( 910), to the CU, the LTM DU configuration and a reference signal resource configuration for at least one reference signal to be transmitted on the target cell.
