Abstract

A docking station is provided, which functions to enable landline telephones connected to the docking station to send and receive “walkie-talkie” or “push-to-talk” (PTT)-type messages via a mobile telephone docked in the docking station. A processor of the docking station is programmed to recognize that when a predefined key of a landline telephone is used, the call is a PTT-type call. The predefined key functions in a manner similar a PTT button on a conventional PTT-type mobile telephone. However, unlike for conventional PTT-type calls, the user need not keep the predefined key pressed when speaking.

Claims

1. A docking station for connecting a cellular telephone with one or more landline telephones of a premises, the docking station comprising:

a line-connection switch configured to detect a condition of at least one landline of the premises and to establish a connection with a landline based on a detected condition, wherein each of the one or more landline telephones is connected to the docking station through the landline;

a processor configured to control a plurality of functions of the docking station; and

a cellular-telephone interface configured to connect with any of a plurality of types of cellular telephones,

wherein the cellular-telephone interface includes a connector configured to connect with a plurality of types of cables through which the docking station communicates with corresponding cellular telephones, and to connect with one or more types of wireless modules through which the docking station communicates wirelessly with corresponding cellular telephones,

wherein an electrical characteristic of a cable or a wireless module connected to the cellular-telephone interface is used by the processor to identify a type of a cellular telephone connected to the docking station, and

wherein the processor is programmed to enable a landline telephone connected to the docking station to send or to receive calls via a walkie-talkie (PTT-type) cellular telephone connected to the docking station;

by translating signals transmitted from the landline telephone to the PTT-type cellular telephone into signals recognizable by the PTT-type cellular telephone, and

by translating signals from the PTT-type cellular telephone to the landline telephone into signals recognizable by the landline telephone.

2. A docking station according to claim 1, wherein the processor is programmed to recognize that, after a telephone number is inputted using a landline telephone connected to the docking station, when a predefined key on the landline telephone is manipulated and released or when a hook switch of the landline telephone is toggled and released the landline telephone is being used to make a PTT-type call and a PTT-type cellular telephone connected to the docking station is to begin calling of the telephone number.

3. A docking station according to claim 1, wherein the processor is programmed to recognize that, when a predefined key or a hook switch of the landline telephone is pressed and released by a user, the user is indicating a beginning of a talking period for the user or and end of a talking period for the user.

4. A docking station according to claim 3, wherein the predefined key is a Flash key.

5. A docking station according to claim 1, wherein the processor notifies the one or more landline telephones of an incoming PTT-type call by causing the one or more landline telephones connected to the docking station to ring with a distinct cadence.

6. A docking station according to claim 1, wherein the processor is programmed to recognize whether a barge-in PTT-type call or whether an alerted PTT-type call is being made from a landline telephone connected to the docking station based a manipulation of on one or more predefined keys on the landline telephone.

7. A docking station according to claim 1, further comprising a built-in telephone unit with a handset, wherein the telephone unit functions as one of the one or more landline telephones connected to the docking station.

8. A docking station according to claim 7,

wherein the a PTT button is included on at least one of the built-in telephone unit and the handset, and

wherein the PTT button is configured to perform functions corresponding to functions performed by a PTT button of a PTT-type cellular telephone.

9. A method of using a landline telephone of a premises to send or to receive a PTT-type telephone call via a cellular telephone connected to a docking station, the method comprising the steps of:

connecting any of a plurality of types of cellular telephones to the docking station via a cable or wirelessly via a wireless module;

detecting a condition of at least one landline of the premises;

establishing a connection with a landline of the premises based on a detected condition, wherein the premises includes one ore more landline telephones and each landline telephone is connected to the docking station through the landline;

identifying a type of the cellular telephone to be a walkie-talkie (PTT-type) cellular telephone, based on an electrical characteristic of a cable or a wireless module connected to the docking station, and

utilizing a processor of the docking station to enable a landline telephone connected to the docking station to send or to receive calls via a walkie-talkie (PTT-type) cellular telephone connected to the docking station;

by translating signals transmitted from the landline telephone to the PTT-type cellular telephone into signals recognizable by the PTT-type cellular telephone, and

by translating signals from the PTT-type cellular telephone to the landline telephone into signals recognizable by the landline telephone.

10. A method according to claim 9, further comprising the step of the processor recognizing that, after a telephone number is inputted using a landline telephone connected to the docking station, when a predefined key on the landline telephone is manipulated and released or when a hook switch of the landline telephone is toggled and released the landline telephone is being used to make a PTT-type call and a PTT-type cellular telephone connected to the docking station is to begin calling of the telephone number.

11. A method according to claim 10, further comprising the step of the processor recognizing that, when a predefined key or a hook switch of the landline telephone is pressed and released by a user, the user is indicating a beginning of a talking period for the user or and end of a talking period for the user.

12. A method according to claim 11, wherein the predefined key is a Flash key.

13. A method according to claim 10, further comprising the step of the processor notifying the one or more landline telephones of an incoming PTT-type call by causing the one or more landline telephones connected to the docking station to ring with a distinct cadence.

14. A method according to claim 10, further comprising the step of the processor recognizing whether a barge-in PTT-type call or whether an alerted PTT-type call is being made from a landline telephone connected to the docking station based a manipulation of on one or more predefined keys on the landline telephone.

15. A method according to claim 10,

wherein the docking station includes a built-in telephone unit with a handset,

wherein the telephone unit functions as one of the one or more landline telephones connected to the docking station,

wherein the a PTT button is included on at least one of the built-in telephone unit and the handset, and

wherein the method further comprises the step of utilizing the PTT button of the built-in telephone or the handset to perform functions corresponding to functions performed by a PTT button of a PTT-type cellular telephone.
