Abstract

Conventional quality of service (QoS) treatment is extended to over-the-top (OTT) applications transmitting data over a commercial wireless network via a virtual private network (VPN) tunnel. An over-the-top (OTT) application server and a VPN client/server routing data to/from that OTT application server via a VPN tunnel, are integrated with a quality of service (QoS) server to enable the OTT application server and/or VPN client/server to request and get desired QoS treatment for application data routed by the OTT application server over the VPN tunnel. The QoS server forwards QoS rules received in a QoS request message to a policy and charging rules function (PCRF) on the OTT application/VPN client devices' home mobile network operator (MNO). If the client device is roaming, the PCRF on the home MNO forwards QoS rules to a PCRF on a serving MNO. QoS treatment is then carried out by the PCRF in a conventional manner.
