Samsung patents phone feature that moves calls to better networks automatically

This patent describes a method where a phone checks if it has received instructions from its current network to switch to a different one. If the phone does not get these instructions within a set time, it moves the call to the second network on its own to keep the connection going.

Why it mattersThis could help prevent dropped calls when a phone is moving between different cellular networks by acting on its own if the network fails to send the usual switch commands.

A method for calling performed by a user equipment (UE) including establishing a call based on a first network in which the UE camps, determining whether a first command for handover or redirection to a second network is received from the first network, and performing an autonomous redirection in response to determining that the first command is not received and a duration between the establishing and the determining exceeds a first threshold, the autonomous redirection redirecting the UE to the second network for continuation of the call.
