Abstract: A device may: receive, from a first network device, an indication that a user equipment device (UE) has established an Internet Protocol (IP) session through a network; subscribe to a notification service, at the first network device, that indicates whether the UE is reachable; determine that quality-of-service (QoS) for the UE needs to be modified; send a first request, to the first network device, to modify a bearer for the UE in response to the determination that the QoS for the UE needs to be modified; receive a first reply, from the first network device, that the QoS for the UE has failed because the UE is unreachable; receive a notification, from the notification service at the first network device, that the UE is reachable; determine whether the QoS for the UE still needs to be modified in response to the notification; and send a second request to the first network device in response to determining whether the QoS for the UE still needs to be modified.
