Abstract

An indicator of a channel capacity of a wireless link between a wired telephone and a wireless hands free device is measured. Based on the indicator of the channel capacity, a call server decides whether to route a call to the wired telephone. The indicator of channel capacity may be is based on measurements of channel capacity between the telephone and the wireless hands free device taken at different times and at different locations. The measurements of channel capacity may be used to construct a map relating physical location and time to channel capacity available between one or more wired telephones and wireless hands free devices. The available channel capacity can also be used to cause indicators associated with low channel capacity to be displayed by the wired telephone or signaled to the wireless hands free device.

Claims

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

establishing a wireless link for audio communication between a wired telephone and a wireless hands free device, the wired telephone having a two-way non-wireless audio user interface and a wireless interface, the wireless link being established via the wireless interface of the wired telephone;

determining, by the wired telephone, an indicator of the minimum communication bandwidth available via the wireless link;

receiving, from the wired telephone, the indicator of the minimum communication bandwidth available via the wireless link; and

,

based on the indicator of the minimum communication bandwidth available via the wireless link, determining whether to route a call to the two-way non-wireless audio user interface of the wired telephone.

2. The method of claim 1, wherein the indicator of the minimum communication bandwidth available via the wireless link is based on measurements of channel capacity between the wired telephone and the wireless hands free device.

3. The method of claim 1, wherein, based on the indicator of the minimum communication bandwidth available via the wireless link, the wired telephone displays an indicator that the wireless hands free device is not available.

4. The method of claim 1, further comprising:

receiving a plurality of indicators of channel capacity of established wireless links between a plurality of wired telephones and a respective plurality of wireless hands free devices; and

,

based on the a plurality of indicators of channel capacity and the indicator of the minimum communication bandwidth available via the wireless link, routing the call to the two-way non-wireless audio user interface of the wired telephone.

5. The method of claim 1, further comprising:

receiving a plurality of indicators of channel capacity of established wireless links between a plurality of wired telephones and a respective plurality of wireless hands free devices; and

,

based on the a plurality of indicators of channel capacity, and a plurality of locations of associated with the plurality of wired telephones, creating a location based map of channel capacity.

6. The method of claim 5, further comprising:

routing a second call to a selected one of the plurality of wired telephones based on the location based map of channel capacity and a location associated with the selected one of the plurality of wired telephones.

7. The method of claim 1, further comprising:

receiving, by the wired telephone, signaling information from the wireless hands free device that corresponds to the capacity of the wireless link between the wired telephone and the wireless hands free device.

8. The method of claim 7, further comprising:

based on the signaling information, selecting a codec configuration for use on the wireless link between the wired telephone and the wireless hands free device.

9. A communication system, comprising:

a plurality of wired telephones each wirelessly coupled to a respective one of a plurality of wireless hands free devices, each of the plurality of wired telephones having a two-way non-wireless audio user interface and a wireless interface, each of the wired telephones determining a respective indicator of a minimum communication bandwidth available for audio communication with the respective wireless hands free device, each of the wired telephones determining whether to route calls to a respective two-way non-wireless audio user interface based on the respective indicator of the minimum communication bandwidth available for audio communication with the respective wireless hands free device;

the plurality of wired telephones including a first wired telephone wirelessly coupled to a first wireless hands free device, the first wired telephone wirelessly coupled to the first wireless hands free device via the wireless interface of the first wired telephone, the first wired telephone determining a first respective indicator of the minimum communication bandwidth available for audio communication with the first wireless hands free device; and

,

a call server configured to route calls to the plurality of wired telephones, the call server configured to receive the respective indicators of the minimum communication bandwidth available for audio communication with the respective wireless hands free device.

10. The communication system of claim 9, wherein the call server is configured to select the first wired telephone for a call based on the first respective indicator.

11. The communication system of claim 9, wherein the call server is configured to select for a call, based on the first respective indicator, one of the plurality of wired telephones that is not the first wired telephone.

12. The communication system of claim 9, wherein the first respective indicator indicates to the call server whether the first wired telephone has enough minimum communication bandwidth available for audio communication with the first wireless hands free device to answer a call using the first less hands free device.

13. The communication system of claim 9, wherein the first wired telephone rejects a call based on the first respective indicator.

14. The communication system of claim 9, wherein the first wired telephone selects a codec for a call based on the first respective indicator.

15. The communication system of claim 9, wherein, in response to a call, the call server signals the first wired telephone is unavailable based on the first respective indicator.

16. The communication system of claim 9, wherein, in response to a call, the call server routes the call to a voice messaging service based on the first respective indicator.

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

determining, by a wired telephone having a two-way non-wireless audio user interface and a wireless interface, a minimum communication bandwidth available for audio communication via an established wireless link between the wired telephone and a wireless hands free device;

based on the minimum communication bandwidth available for audio communication via the established wireless link, signaling a user of the wireless hands free device that the minimum communication bandwidth available for audio communication meets a threshold requirement; and

,

based on the minimum communication bandwidth available for audio communication via the established wireless link, determining whether to route audio communication associated with a call to a two-way non-wireless audio interface of the wired telephone.

18. The method of claim 17, wherein the threshold requirement corresponds to a sufficient minimum available communication bandwidth between the wired telephone and the wireless hands free device.

19. The method of claim 18, wherein the user is signaled using a first ringtone if the threshold requirement is met and a second ringtone if the threshold requirement is not met.

20. The method of claim 19, further comprising:

routing, by a call server, the call to the d telephone based on based on the threshold requirement being met.
