Abstract

In order to facilitate operation of a mobile station for a mobile telecommunications system comprising a handset and a headset for connection to the handset, the handset including RF transceiver means for transmitting an outgoing call and receiving an incoming call, processor means coupled to the RF transceiver means for providing audio signals on a first audio path to audio transducer means in the handset and on a second audio path for audio transducer means in the headset, the headset and the handset include respective button switches arranged that operation has the effect both of initiating and/or accepting a call, and of routing audio signals to the respective first or second audio path. Embodiments are described including a separate switch for toggling the audio paths, and automatic sensors for detecting use of the headset or handset.

Claims

1. A mobile station for a mobile telecommunications system comprising a handset

and a headset for connection to the handset,

the handset including RIF transceiver means for transmitting an outgoing call and

receiving an incoming call, processor means coupled to the RIF transceiver means

for providing audio signals on a first audio path to audio transducer means in the handset and on a second audio path for audio transducer means in the headset, characterised in that:

the headset and/or the handset includes a switch means arranged such that operation thereof has the effect both of initiating and/or accepting a call, and of routing audio signals to a selected one of the first and second audio paths.

2. A mobile station according to claim 1, wherein the audio transducer means in the headset and handset each comprise a microphone and loudspeaker.

3. A mobile station according to claim 1, wherein the first mentioned switch means is located in the handset and a second switch means having similar functions is located in the headset.

4. A mobile station according to claim 1, including switch control means in the processor means responsive to operation of the first mentioned switch means, for operating respective further switch means in the first audio path and in the second audio path for selection thereof.

5. A mobile station according to claim 1, wherein further operation of the first switch means is operative to terminate a call.

6. A mobile station according to claim 3, wherein the first switch means is located in the handset and a second switch means having similar functions is located in the headset, and wherein operation of the first switch means followed by operation of the second switch means, or vice versa, is effective to select the other of the selected one of the first and second audio paths.

7. A mobile station according to claim 1, arranged such that further operation of the first mentioned switch means is operative to terminate a call.

8. A mobile station for a mobile telecommunications system comprising a handset and a headset for connection to the handset, the handset including RIF transceiver means for transmitting an outgoing call and receiving an incoming call, processor means coupled to the RIF transceiver means for providing audio signals on a first audio path to audio transducer means in the handset and on a second audio path for audio transducer means in the headset, characterised in that:

the headset and/or the handset includes a first switch means operative upon receipt of an incoming call to accept the call, and a second switch means, manually operable for toggling the audio path to a selected one of the loudspeaker and headset.

9. A mobile station for a mobile telecommunications system comprising a handset and a headset for connection to the handset,

the handset including RF transceiver means for transmitting an outgoing call and receiving an incoming call, processor means coupled to the RF transceiver means for providing audio signals on a first audio path to audio transducer means in the handset and on a second audio path for audio transducer means in the headset, characterised by:

means (S, T) for detecting use of the headset or handset by the user and coupled to audio path control means for automatically enabling the respective first or second audio path to the set in use.

10. A mobile station according to claim 9, wherein the detecting means comprises a capacitance sensing means located in the handset for detecting proximity of a user'"'"'s head.

11. A mobile station according to claim 9, wherein the detecting means comprises infrared sensing means located in the handset for detecting proximity of a user'"'"'s head.

12. A mobile station according to claim 9, wherein the detecting means comprises acoustic impedance sensing means located in the handset for detecting proximity of a user'"'"'s head.

13. A mobile station according to claim 9, wherein the detecting means comprises sensing means located in the headband of the handset for detecting use on a user'"'"'s head.

16. A method according to claim 15, including further operating the switch means in order to terminate the call.

17. A method according to claim 15, wherein the first mentioned switch means is located in the handset and a second switch means having similar functions is located in the headset, and depending on which of the first and second switch means is operated, the audio is routed to the respective set.

18. A method according to claim 17, comprising operating one switch means following operation of the other switch means, whereby to route the audio to the audio path not currently in use.

14. A mobile station for a mobile telecommunications system comprising a handset and a headset for connection to the handset,

the handset including RIF transceiver means for transmitting an outgoing call and receiving an incoming call, processor means coupled to the RF transceiver means for providing audio signals on a first audio path to audio transducer means in the handset and on a second audio path for audio transducer means in the headset, characterised by:

means operative upon initiation of an outgoing call or acceptance of an incoming call to the station to selectively route the audio path to one of the headset and handset.

15. A method of operating a mobile station for a mobile telecommunications system , the mobile station comprising a handset and a headset for connection to the handset, the handset including RIF transceiver means for transmitting an outgoing call and receiving an incoming call, processor means coupled to the RF transceiver means for providing audio signals on a first audio path to audio transducer means in the handset and on a second audio path for audio transducer means in the headset, and switch means for accepting or initiating a call, the method being characterised by monitoring the handset for receipt of an incoming call and if detected, operating said switch means to accept the call, and routing the audio to a selected one of the first and second audio paths, and if an incoming call is not detected, but said switch means is operated, initiating a call, and routing the audio to a selected one of the first and second audio paths.
