1. A system comprising:
a wireless device comprising a first one or more processors;
a policy and charging rules function (PCRF) comprising a second one or more processors;
a policy and charging enforcement function (PCEF) comprising a third one or more processors;
a first memory storing instructions that, when executed by the first one or more processors, cause the wireless device to perform operations comprising:
determining a change in a signal quality measurement of one or more radio signals of a base station of a wireless network; and
transmitting, to a video application function (AF) and in response to the determining a first message for modifying a quality of service (QoS) of one or more media for an ongoing video call in the wireless network;
a second memory storing instructions that, when executed by the second one or more processors, cause the PCRF to perform operations comprising:
receiving, from the video AF, a DIAMETER AA-request (AAR) command for modifying the QoS of the video call;
transmitting, to the PCEF, a second message comprising an updated QoS, wherein the updated QoS comprises QoS data bearer modification information based on the change in the signal quality measurement of the one or more radio signals of the base station; and
a third memory storing instructions that, when executed by the third one or more processors, cause the PCEF to perform operations comprising:
implementing, by the PCEF, the updated QoS for the video call.
