Abstract

To determine a cause of a customer experience event (e.g., dropped call or choppy video) passively collected measures from various network layers (e.g., internet, transport, application, etc.) are used to establish user activity across multiple service types (a.k.a., contexts). These contexts are monitored across parallel contexts, services, and/or sockets. The multiple contexts are aggregated for analysis. The multiple contexts can be analyzed to determine a cause of the customer experience event.

Claims

1. A method of operating a communication system, comprising:

receiving an indicator of a customer experience event associated with a wireless device;

determining a service type associated with the wireless device and the customer experience event;

receiving a plurality of indicators associated with the customer experience event, the plurality of indicators comprising throughput information about at least two data streams that the wireless device was engaged in at the time of the customer experience event, wherein the throughput information is reported by each of an application layer, a network layer, and an air-interface layer;

determining a throughput experienced by a first application that did not report a throughput measurement, based on throughput information reported by any combination of a second application on the application layer, the network layer, and the air-interface layer;

aggregating the throughput information for the at least two data streams based on the service type; and

based on the aggregated throughput information, determining a cause of the customer experience event.

2. The method of claim 1, further comprising:

passively gathering said plurality of indicators.

3. The method of claim 2, wherein said plurality of indicators are based on traffic associated with a plurality of applications running on said wireless device.

4. A communication system, comprising:

a plurality of network layers associated with communication with a wireless device, the plurality of network layers comprising an application layer, a network layer, and an air-interface layer, the plurality of network layers being configured to measure and report a plurality of throughput indicators comprising throughput information about at least two data streams that the wireless device was engaged in at the time of a customer experience event; and

,

an event analyzer configured to determine a service type of a customer experience event, determine a throughput experienced by a first application that did not report a throughput measurement, based on throughput information reported by any combination of a second application on the application layer, the network layer, and the air-interface layer, determine an aggregate throughput of the plurality of indicators based on the service type and, based on the aggregated throughput, determine a cause of the customer experience event.

5. The communication system of claim 4, wherein the plurality of network layers are configured to measure the plurality of throughput indicators passively.

6. A communication system, comprising:

a first processing node, configured to;

receive an indicator of a customer experience event associated with a wireless device;

determine a service type associated with the wireless device and the customer experience event;

receive a plurality of indicators associated with the customer experience event, the plurality of indicators associated with the customer experience event being reported by an application layer, a network layer, and an air-interface layer and comprising throughput information about at least two data streams that the wireless device was engaged in at the time of the customer experience event

determine a throughput experienced by a first application that did not report a throughput measurement, based on throughput information reported by any combination of a second application on the application layer, the network layer, and the air-interface layer,

aggregate the throughput information for the at least two data streams based on the service type; and

based on the aggregated throughput information, determine a cause of the customer experience event.

7. The communication system of claim 6, further comprising:

a second processing node, configured to;

passively gather at least one of said plurality of indicators associated with the customer experience event.
