Mobile device and method attributing media services network usage to requesting application

What is this patent about?

’918 is related to the field of wireless network management and device-assisted service usage accounting. Specifically, it addresses the technical challenge of accurately attributing data consumption to specific applications when those applications use intermediate operating system functions, such as media players or download managers, to handle their network traffic. In modern mobile operating systems, traditional network stack monitoring often incorrectly credits data usage to these system proxies rather than the originating application, leading to inaccurate billing and ineffective policy enforcement.

The underlying idea behind ’918 is to bridge the visibility gap between high-level application requests and low-level network data flows by implementing a multi-stage tracking mechanism. The invention recognizes that while an application may not open a network socket directly, it initiates a request through a specialized API for a specific media object or network resource. By capturing the association between the originating application and the resource identifier at the moment of the request, the system can later map the resulting background data transfers back to the correct source, even if the traffic is physically managed by a common system service.

The claims of ’918 focus on a device architecture that utilizes two distinct Application Programming Interfaces (APIs) to track and reconcile data usage. The first API handles standard, direct data flows, while the second API is specifically designed for media object requests associated with network resource identifiers like URLs or IP addresses. A media service manager coordinates the actual transfer, while service classification and measurement agents perform the critical task of attributing usage from both APIs to the specific originating application to maintain an accurate, aggregate record of its total network footprint.

In practice, the invention works by monitoring the media service manager to intercept data transfer requests before they are handed off to the network stack. When an application like a streaming music client requests a song via a URL, the system records the application's identity and the specific resource identifier. As the network stack begins the download, the classification agent uses these stored associations to virtually or literally tag the resulting packets. This allows the device to distinguish between different applications that may all be using the same system-level media library simultaneously.

This approach differs from prior solutions by moving beyond simple socket-to-process mapping, which typically fails when a proxy service manager is involved. Instead of allowing system services to mask the identity of data-hungry applications, ’918 provides a reconciliation element that aggregates usage across different access methods. This ensures that service providers can implement granular traffic controls and sponsored billing models that remain accurate regardless of whether an application communicates directly with the network or offloads its tasks to the operating system's background services.
