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:

receiving an indicator of a channel capacity of a wireless link between a wired telephone and a wireless hands free device; and

,

based on the indicator of the channel capacity, determining whether to route a call to the wired telephone.

2. The method of claim 1, wherein the indicator of channel capacity is based on measurements of channel capacity between the telephone and the wireless hands free device.

3. The method of claim 1, wherein, based on the indicator of the channel capacity, the 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 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 channel capacity, routing the call to the telephone.

5. The method of claim 1, further comprising:

receiving a plurality of indicators of channel capacity of 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 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 codec configuration for use on the link between the wired telephone and the wireless hands free device.

9. A communication system, comprising:

a plurality of wired telephones coupled to a plurality of wireless hands free devices, respectively, the plurality of wired telephones including a first telephone coupled to a first wireless hands free device; and

,

a call server configured to route calls to the plurality of wireless hands free devices via the plurality of telephones, the call server configured to receive a first indicator of a first channel capacity of a first wireless link between the first telephone and the first wireless hands free device.

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

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

12. The communication system of claim 9, wherein the first indicator of the first channel capacity of the first wireless link indicates whether the first wireless hands free device has enough channel capacity to answer a call.

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

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

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

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

determining an indicator of a channel capacity of a wireless link between a wired telephone and a wireless hands free device; and

,

based on the indicator of the channel capacity, signaling a user of the wireless hands free device that the indicator of channel capacity meets a threshold requirement.

18. The method of claim 17, wherein the threshold requirement corresponds to a minimum available communication bandwidth between the wired telephone and a 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, a call to the wired telephone based on based on the threshold requirement being met.
