20110219431 | SYSTEM AND METHOD OF QUALITY OF SERVICE ENABLEMENT FOR OVER THE TOP APPLICATIONS IN A TELECOMMUNICATIONS SYSTEM - A system, method, and node providing a predefined Quality of Service (QoS) level to an Over The Top (OTT) service provider in a telecommunications network. A User Equipment (UE) initiates an IP-based application session (e.g., Hyper Text Transfer Protocol (HTTP) session) with the OTT service provider by sending an application-dependent message toward an OTT application server. The method begins with a proxy node in the telecommunications network intercepting the application-dependent message. The proxy node then modifies the application-dependent message by adding a subscriber identification to the header of the application-dependent message. The proxy node forwards the modified application-dependent message to the OTT application server. The OTT application server then sends a request having the subscriber identification to the telecommunications network with a QoS requirement for the HTTP session. Next, a network policy node determines an appropriate QoS level for the subscriber. A network gateway then enforces the determined QoS level for the HTTP session with the OTT service provider. | 09-08-2011 |
