Abstract: Systems and method are provided that allow an application layer client in a mobile device to manage multiple interfaces in a communication network. The multiple interfaces can include WiFi, cellular, Femto, WiMAX, Bluetooth, infrared, Ethernet, and other types of interfaces for communication in a network. The client on the mobile device can use intelligence and rules to determine how and when request fragments are communicated over the various interfaces available to the client. The intelligence can include parameters such as performance information for a particular interface and subscriber preferences. Based on this information the client can decide to use a combination of the interfaces to obtain multimedia content and render the content for display on the mobile device. By using a combination of interfaces and tracking the advantages and disadvantages of each interface, the client can make intelligent decisions in providing multimedia content to the user.

Abstract: Systems and methods for modifying a media protocol based on subscriber and network performance information is disclosed. Media protocols such as adaptive bitrate protocol can adjust bit rates based on conditions perceived at the mobile device and with a goal of obtaining the highest bit rate possible. The media protocols residing on the mobile device do not have access to network performance information that can change rapidly and impact the experience at the mobile device. For example, congestion, radio air link interference, handoffs, and quality of service parameters can all impact the experience a user has when accessing media files from a mobile device. The requests made by a mobile device can be modified to take into account these factors to enhance the user experience.
