Abstract

A method for establishing a communication link between a telecommunications network and a mobile station via a local station connected to said telecommunications network and a short range radio channel between said local station and said mobile station comprises a step in which at least one property of said radio channel is negotiated between said local station and said mobile station, a step in which said mobile station enters a power saving mode, a step in which said mobile station enters an active mode, and a step in which said local station links said mobile station to said telecommunications network via said radio channel using said at least one negotiated property. A local station and a mobile station have corresponding features. The invention is especially adapted for portable telephone and data transmission devices.

Claims

1. A local station configurable for establishing a communication link between a telecommunications network and a mobile station, the local station comprising:

a wireless network transceiver adapted for communication via a short range radio channel; and

a controller operatively coupled to the telecommunications network and the wireless network transceiver, the controller being operative to;

(a) contact the mobile station via the radio channel and negotiate at least one property of the radio channel;

(b) receive a call indication from the telecommunications network and send an activation message to the mobile station via the radio channel, whereby the mobile station enters an active mode in response to receiving the activation message; and

(c) link the mobile station to the telecommunications network via the radio channel using the at least one negotiated property.

2. The local station of claim 1, wherein the short range radio channel is a frequency hop, time division duplex (FH/TDD) channel.

3. The local station of claim 1, wherein the telecommunication network is a wire-based network.

4. The local station of claim 1, wherein the controller is further operative to receive a communication request from the mobile station in response to a user input and send an acknowledgment to the mobile station.

6. The method of claim 1,

wherein step c) comprises the step of negotiating at least one of the following properties of said radio channel:

transmission power level,

voice transmission quality,

voice transmission protocol,

data transmission rate,

data transmission protocol, and

error correction and/or recovery method.

7. The method of claim 6,

wherein step c) further comprises the step of negotiating at least one property of said local station and/or said mobile station.

9. The method of claim 7, wherein step c) further comprises the step of negotiating one or more priorities of at least one of said local station and said mobile station with respect to incoming call indications.

17. The mobile station of claim 9, wherein the controller is further operative to:

(f) send a communication request to the local station in response to a user input; and

(g) receive an acknowledgment from the local station in response to the local station receiving the communication request.

18. The mobile station of claim 17, wherein the controller, in response to not receiving the acknowledgment from the local station within a predetermined time, is operative to use a further radio channel for fulfilling the communication request.

19. The mobile station of claim 18,

wherein said mobile station is a GSM handset comprising the wireless network transceiver, the GSM handset further comprising a GSM radio unit coupled to the controller for establishing at least one of a long range radio channel and a cellular radio channel.

20. The mobile station of claim 18, wherein said further channel is at least one of a long range radio channel and a cellular radio channel.

21. The mobile station of claim 20,

wherein said mobile station is a GSM handset comprising the wireless network transceiver, the GSM handset further comprising a GSM radio unit coupled to the controller for establishing at least one of a long range radio channel and a cellular radio channel.

5. A method for establishing a communication link between a telecommunications network and a mobile station via a local station connected to said telecommunications network and a short range radio channel between said local station and said mobile station, said method comprising the steps of:

a) said local station and said mobile station contacting each other via said radio channel and negotiating at least one property of said radio channel,

b) said mobile station entering a power saving mode,

c) said local station receiving a call indication from said telecommunications network and sending an activation message to said mobile station via said radio channel,

d) said mobile station receiving said activation message and entering an active mode, and

e) said local station linking said mobile station to said telecommunications network via said radio channel using said at least one negotiated property.

8. The method of claim 5,

wherein step c) further comprises the step of negotiating at least one property of said local station and/or said mobile station.

10. The method of claim 8, wherein step c) further comprises the step of negotiating one or more priorities of at least one of said local station and said mobile station with respect to incoming call indications.

11. The method of any one of claims 5 to 8, further comprising the steps of:

f) said mobile station sending a communication request to said local station in response to a user input,

g) said local station receiving said communication request and sending an acknowledgement to said mobile station, and

h) said local station linking said mobile station to said telecommunications network via said radio channel using said at least one negotiated property.

12. The method of claim 11,

wherein said mobile station, in response to not receiving said acknowledgement from said local station within a predetermined time, uses a further radio channel for fulfilling said communication request.

13. The method of claim 12,

wherein said further radio channel is at least one of a long range radio channel and a cellular radio channel.

14. The method of any one of claims 5 to 8,

wherein said telecommunication network is a wire-based network.

15. The method of any one of claims 5 to 8,

wherein said short range radio channel is a frequency hop, time division duplex (FH/TDD) channel.

16. A mobile station configurable for communication with a telecommunications network via a local station connected to the telecommunications network, the mobile station comprising:

a wireless network transceiver adapted for communication via a short range radio channel; and

a controller operatively coupled to the wireless network transceiver, the controller being operative to;

(a) contact the local station via the radio channel and negotiate at least one property of the radio channel;

(b) enter a power saving mode;

(c) receive an activation message from the local station via the radio channel in response to a call indication received by the local station from the telecommunications network;

(d) upon receiving the activation message, enter an active mode; and

(e) link to the telecommunications network via the radio channel using the at least one negotiated property.

22. The mobile station of claim 16,

wherein said mobile station is a GSM handset comprising the wireless network transceiver, the GSM handset further comprising a GSM radio unit coupled to the controller for establishing at least one of a long range radio channel and a cellular radio channel.

23. The mobile station of claim 16, wherein the short range radio channel is a frequency hop, time division duplex (fh/tdd) channel.

24. The mobile station of claim 23,

wherein said mobile station is a GSM handset comprising the wireless network transceiver, the GSM handset further comprising a GSM radio unit -coupled to the controller for establishing at least one of a long range radio channel and a cellular radio channel.

25. The mobile station of claim 16, wherein the telecommunication network is a wire-based network.

26. The mobile station of claim 25,

wherein said mobile station is a GSM handset comprising the wireless network transceiver, the GSM handset further comprising a GSM radio unit coupled to the controller for establishing at least one of a long range radio channel and a cellular radio channel.
