End-to-end quality of service control for a remote service gateway
Systems and methods of performing end-to-end QoS control during the access of Wi-Fi-enabled communications devices to remote networks. The systems and methods employ a bandwidth manager, a policy server, a near-end gateway located within a Wi-Fi network, and a far-end gateway located within a service provider network. Throughout the duration of a call placed by a wireless device user using a Wi-Fi-enabled communications device, the bandwidth manager can have access to service profiles stored in a database of the policy server for use in monitoring levels of bandwidth usage, for tunneled and/or local breakout traffic, at least at the near-end gateway to the service provider network and at the far-end gateway to a remote network, and performing end-to-end QoS control by dynamically making adjustments, as needed, to one or more service profiles at least at the near-end gateway and/or at the far-end gateway based on the monitored bandwidth usage levels.
