Abstract

Claims (72)

1. A wireless communications system comprising:

an access device configured to provide a wireless link between the wireless communications system and a mobile device; and

implement a voice-communication session for communicating voice data between the mobile device and at least one end-point device;

receive a session-end message, including a mute report,

wherein the session-end message is for signaling an end of the voice-communication session according to an input from a user of the mobile device;

determine, at the mobile device, a packet drop rate using a total number of reported absences in packets during the voice-communication session and a total number of communicated packets or a total session duration;

generate, at the mobile device, a radio condition indicator that represents one or more conditions associated with the wireless link during the voice-communication session,

wherein the radio condition indicator includes the determined packet drop rate;

determine a mute report based on the session-end message, wherein the mute report represents a mute event detected by the mobile device during the voice-communication session, and

wherein the mute report includes, for the mute event, the radio condition indicator and at least two of:

a duration of the mute event,

a direction of the mute event,

a geographic location associated with of the mute event, or

a time of the mute event, and

wherein the mute report is determined according to a predetermined format that designates values and/or bit locations within the session-end message for the mute report.

2. The wireless communications system of claim 1 , further comprising a network analyzer coupled to or included in the IMS network, the network analyzer configured to:

crowd-sourcing a set of mute reports representative of mute events across a set of corresponding voice-communication sessions,

wherein the set of mute reports includes the determined mute report; and

identifying an estimated cause associated with the determined mute report based on analyzing the set of mute reports,

wherein the estimated cause represents a geographic location, the access device, a manufacturer, or a device type corresponding to the mobile device, a network condition, or a combination thereof associated with the set of mute reports.

3. The wireless communications system of claim 1 , wherein the mute report represents the mute event occurring at a beginning portion of the voice-communication session and/or occurring intermittently during the voice-communication session.

4. The wireless communications system of claim 1 , wherein the mute report is determined based on parsing a text header to identify one or more text strings that represent a mute event status, a duration, a direction, a radio condition indicator, a corresponding delimiter, or a combination thereof.

5. The wireless communications system of claim 1 , wherein the mute report is separate from a Call Detail Record (CDR) and a link quality data configured to describe the wireless radio link to the access device.

6. An apparatus for use in a wireless communications system, the apparatus comprising:

at least one hardware data processor, wherein the at least one hardware processor is coupled to an Internet Protocol (IP) Multimedia Core Network Subsystem (IMS) network, and

wherein the IMS network is coupled to an access device configured to provide a wireless link with a mobile device; and

at least one memory device coupled to the at least one hardware data processor and storing instructions, which when executed by the at least one hardware data processor performs operations to:

implement a voice-communication session for communicating voice data between the mobile device and at least one end-point device;

receive a session-end message, wherein the session-end message is for signaling an end of the voice-communication session according to an input from a user of the mobile device;

determine, at the mobile device, a packet drop rate using a total number of reported absences in packets during the voice-communication session and a total number of communicated packets or a total session duration;

generate, at the mobile device, a radio condition indicator that represents one or more conditions associated with the wireless link,

wherein the radio condition indicator includes the determined packet drop rate;

determine a mute report based on the session-end message, wherein the mute report represents a mute event detected by the mobile device during the voice-communication session, and

wherein the mute report includes, for the mute event, the radio condition indicator and at least one of:

a duration of the mute event,

a direction of the mute event,

a geographic location associated with of the mute event, or

a time of the mute event, and

wherein the mute report is determined according to a predetermined format that designates values and/or bit locations within the session-end message for the mute report.

7. The apparatus of claim 6 , further comprising a network analyzer coupled to the at least one hardware data processor, the network analyzer configured to:

crowd-sourcing a set of mute reports representative of mute events across a set of corresponding voice-communication sessions,

wherein the set of mute reports includes the determined mute report; and

identifying an estimated cause associated with the determined mute report based on analyzing the set of mute reports,

wherein the estimated cause represents the geographic location, the access device, a manufacturer, or a device type corresponding to the mobile device, a network condition, or a combination thereof associated with the set of mute reports.

8. The apparatus of claim 6 , wherein the mute report represents the mute event occurring at a beginning portion of the voice-communication session and/or occurring intermittently during the voice-communication session.

9. The apparatus of claim 6 , wherein the mute report is determined based on parsing a text header to identify one or more text strings that represent a mute event status, the duration, the direction, a radio condition indicator, a corresponding delimiter, or a combination thereof.

10. The apparatus of claim 6 , wherein the mute report is determined according to a predetermined format that designates values and/or bit locations within the session-end message for the mute report.

11. The apparatus of claim 6 , wherein the IMS network is further configured to determine a radio condition indicator representative of one or more conditions associated with a wireless link between the wireless device and the access device during the voice-communication session, wherein the mute report includes the radio condition indicator for the mute event.

12. The apparatus of claim 6 wherein the mute report is separate from a Call Detail Record (CDR) and a link quality data configured to describe the wireless link to the access device.

13. A method comprising:

implementing a voice-communication session for communicating voice data between a mobile device and at least one end-point device;

receiving a session-end message, including a mute report,

wherein the session-end message is for signaling an end of the voice-communication session according to an input from a user of the mobile device;

determining, at the mobile device, a packet drop rate using a total number of reported absences in packets during the voice-communication session and a total number of communicated packets or a total session duration;

generating, at the mobile device, a radio condition indicator that represents one or more conditions associated with a wireless radio link during the voice-communication session,

wherein the radio condition indicator includes the determined packet drop rate;
