Abstract

A method, computer program product and system for determining quality of experience indicator in a telecommunication network including core network and radio access network (RAN) are provided. Quality of service indicators for a subscriber'"'"'s session associated with the core network are received. Quality characteristics of a radio signal transmitted through the RAN or obtained from the user equipment and correlated to the subscriber'"'"'s session are determined. A quality of experience indicator is generated for the subscriber'"'"'s session based on the quality of service indicators for the core network and the quality characteristics of the radio signal.

Claims

1. A method for determining quality of experience indicator in a telecommunication network including core network and radio access network (RAN) signaling, the method comprising the steps of:

receiving quality of service indicators for a subscriber'"'"'s session associated with the core network;

determining, by a processor, quality characteristics of a radio signal transmitted through the RAN and correlated to the subscriber'"'"'s session; and

generating a quality of experience indicator for the subscriber'"'"'s session based on the quality of service indicators for the core network and the quality characteristics of the radio signal.

2. The method of claim 1, wherein said core network comprises an Internet Protocol (IP) network.

3. The method of claim 1, wherein determining quality characteristics of a radio signal comprises analyzing radio bearer and radio access bearer signaling.

4. The method of claim 1, wherein determining quality characteristics of a radio signal comprises determining cell coverage and capacity for a cell serving the subscriber'"'"'s session.

5. The method of claim 2, wherein quality of service indicators for the subscriber'"'"'s session comprise at least one of:

TCP latency value, round trip time (RTT) value, user datagram protocol (UDP) jitter value, real-time transport protocol (RTP) jitter value or calculated MOS score.

6. The method of claim 1, wherein the subscriber'"'"'s session includes at least one of data content, voice over internet protocol (“

VOIP”

) content, video on demand (“

VOD”

) content, streaming audio content, or streaming video content.

7. The method of claim 3, wherein said analyzing radio bearer and radio access bearer signaling comprises analyzing a plurality of neighbor cell handover parameters.

8. The method of claim 3, wherein said analyzing radio bearer and radio access bearer signaling comprises determining signal quality based on a plurality of Uu interface signaling parameters.

9. The method of claim 1, wherein the quality characteristics of the radio signal are correlated to the subscriber'"'"'s session by correlating subscriber'"'"'s temporary identity information with subscriber'"'"'s permanent identity information.

10. A computer program product for determining quality of experience indicator in a telecommunication network including a core network and radio access network (RAN), the computer program product comprising:

one or more computer-readable storage devices and a plurality of program instructions stored on at least one of the one or more computer-readable storage devices, the plurality of program instructions comprising;

program instructions to receive quality of service indicators for a subscriber'"'"'s session associated with the core network;

program instructions to determine quality characteristics of a radio signal transmitted through the RAN and correlated to the subscriber'"'"'s session; and

program instructions to generate a quality of experience indicator for the subscriber'"'"'s session based on the quality of service indicators for the core network and the quality characteristics of the radio signal.

11. The computer program product of claim 10, wherein said core network comprises an Internet Protocol (IP) network.

12. The computer program product of claim 10, wherein the program instructions to determine quality characteristics of a radio signal comprise program instructions to analyze radio bearer and radio access bearer signaling.

13. The computer program product of claim 10, wherein the program instructions to determine quality characteristics of a radio signal comprise program instructions to determine cell coverage and capacity for a cell serving the subscriber'"'"'s session.

14. The computer program product of claim 11, wherein the program instructions to determine quality characteristics of a radio signal comprise program instructions to analyze operational support system (OSS) configuration and performance information.

15. The computer program product of claim 10, wherein the subscriber'"'"'s session includes at least one of data content, voice over internet protocol (“

VOIP”

) content, video on demand (“

VOD”

) content, streaming audio content, or streaming video content.

16. The computer program product of claim 10, wherein the program instructions to analyze radio access bearer signaling comprise program instructions to analyze a plurality of neighbor cell handover parameters.

17. A computer system for determining quality of experience indicator in a telecommunication network including a core network and radio access network (RAN), the computer system comprising one or more processors, one or more computer-readable storage devices, and a plurality of program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors, the plurality of program instructions comprising:

program instructions to receive quality of service indicators for a subscriber'"'"'s session associated with the core network;

program instructions to determine quality characteristics of a radio signal transmitted through the RAN and correlated to the subscriber'"'"'s session; and

program instructions to generate a quality of experience indicator for the subscriber'"'"'s session based on the quality of service indicators for the core network and the quality characteristics of the radio signal.

18. The computer system of claim 17, wherein said core network comprises an Internet Protocol (IP) network.

19. The computer system of claim 17, wherein the program instructions to determine quality characteristics of a radio signal comprise program instructions to analyze radio bearer and radio access bearer signaling.

20. The computer system of claim 17, wherein the program instructions to determine quality characteristics of a radio signal comprise program instructions to determine cell coverage and capacity for a cell serving the subscriber'"'"'s session.
