WIRELESS WIDE AREA NETWORK CHARGER AND CRADLE

Field of the Disclosure

The present disclosure relates generally to telephony.

Description of the Related Art

The popularity of wireless wide area network telephony, such as cellular and PCS systems, has grown dramatically in the recent past, and the growth trend shows few signs of abating. Many people currently utilize Personal Communication Services (PCS) telephones, which typically operate in frequency ranges of between 1850 to 1910 MHz, and 1930-1990 MHz. PCS carriers are using Global Systems for Mobile communications (GSM), Personal Access Communications Systems (PACS), as well as TDMA and CDMA technology, among others. In addition to standard calling features such as call forwarding, caller ID, and voice mail, PCS phones can provide other features such as video display and text messaging.

Numerous members of the present generation of young people in America, e.g., teenaged to late twenties, have grown up with PCS telephones, and typically only use PCS telephones, i.e., this generation typically does not own a wired, landline telephone. This situation is even more common in many western European and Asian counties. The standard operationing procedure amongst this generation is to have their PCS phone with them 24X7. When their PCS phones need to be recharged, they plug the PCS phone into a charger at home or at the office. However, a call, text, or video message can be missed during the duration of the charging process, which makes many of these users uncomfortable.

Accordingly, an apparatus, or method that overcomes these problems, would be useful.

FIG. 2 is a block diagram illustrating an embodiment of a wireless wide area network telephone docking apparatus 200 with a range of features. Docking apparatus 200 may also be referred to as base station 200. Telephone docking apparatus 200 features a wireless wide area network telephone interface 101 for charging a wireless wide area network telephone 201, as well as for providing access to the other feature modules within the docking apparatus 200. In addition, base station 200 contains an interface/charger 102 for charging a battery in a wireless local area telephone 122. In an embodiment, the wireless wide area network telephone 201 is a PCS telephone. Wireless local area telephone 102 can be a wireless local area handset, a wireless local area telephone having a handset, or a desktop telephone.

Other modules in the base station include display control module 107, call control module 110, a digital interface module 111 and keypad control module 106. Each of the modules 106, 107, 110, and 111 are coupled to the interface 101 to monitor and/or receive data to be handled by each specific module. While the connection to the interface 101 is illustrated as a common connection, such as a bus, it will be appreciated that other connections would be anticipated herein.

In operation, display control module 107 monitors information received at the interface 101, the keypad 105, and the digital interface module 111 to determine when information has been received that should be displayed on the LCD display 120. The call control module 110 monitors information received from the wireless wide area network phone 201 at the interface 101 that is to be communicated to the wireless local area telephone 122 via the antenna 116, and/or to the speaker phone 103.

The portable media read/write interface 114 serves as a standardized input/output interface for communicating with portable external devices, e.g., digital storage cards, also known as media read write sticks. Examples of digital storage cards are the Smart Media card or CompactFlash card. The media read/write interface 114, in conjunction with digital interface module 111, enables transfer of data, e.g., images, from the external devices to LCD display 120, and to a display window (not shown) in the wireless wide area network telephone 201.

Other external devices can be connected to the standardized universal serial bus (USB) interface 112 to transfer data, e.g., images, text, telephone numbers, and the like, to the digital interface module 111, which then migrates the data to a wireless wide area network telephone 201 in the interface/charger location 101 of docking apparatus 200. Examples of external devices which may utilize USB interface 112 include a personal computer (PC), a camera, a personal data assistant (PDA), a dialer, and the like. As part of its call transfer capabilities, the apparatus 200 of Fig. 2 facilitates a frequency conversion. When an incoming wireless wide area network telephone call is received by a wireless wide area network telephone 201 docked in docking apparatus 200, the call is received based on a first protocol, such as a PCS protocol, at a first frequency. This call is ultimately communicated to the wireless local phone at a different frequency, using a different protocol and frequency.

The call control module 110 utilizes a radio frequency driver to communicate with the wireless local area telephone 122 at approximately 2.4 GHz, 5.8 GHz, or other frequency, e.g., 900 MHz. In this way the frequency of the incoming wireless wide area telephone call is converted from the frequency of the wireless wide area telephone to another frequency, e.g., that of the wireless local area telephone. The incoming call with the converted frequency is then relayed to the antenna 116 for transmission to the wireless local area telephone 122. The transfer/relay process preferably appears seamless to the user of the docking apparatus.

If the incoming wireless wide area network call is a text message or video image, docking apparatus 200 can display the message or image on visual display 120. The process is facilitated by the display control module 107 and the video/text message detection module 108, which detects when text information is to be displayed. A keypad control module 106 is also connected to an alphanumeric keypad 105, such that a user's keystrokes on keypad 105 can be detected and displayed in the visual display 120 and control the telephone 201 or 122. Similarly, keystrokes on the wireless local area telephone 122 can be detected by the display control module 107 and displayed by LCD display 120.

A speakerphone 103 with a speaker 123 and a microphone 104 is also provided so that a user of the base station 200 has a "hands-free" option when receiving or making a voice call. Typically, one portion of call controller 110 will interface with the speakerphone 103, while a second portion of call controller 110 will interface with the antenna 116. A power supply line 117 provides power to the base station 200. Power supply line 117 may a 110/220 VAC auto sense transformer which plugs into a wall receptacle to supply 12- volt DC power to the base station 200.

It will be appreciated that other components may be incorporated into the telephone docking apparatus 200 which are not specifically illustrated herein. Examples of other components can include proprietary or non- proprietary interfaces to allow communication to devices to permit coordination of telephone information, or to provide automated dialing. Functions to perform voice processing, call processing, and logic and/or protocol processing, would then be provided by the telephone docking apparatus 200.

FIG. 3 is a flow diagram illustrating a method for relaying wireless wide area network telephone calls to a wireless local area telephone. For purposes of example, the wireless wide area network telephone will be discussed in conjunction with FIG. 3 as a PCS telephone. The PCS telephone is placed in the PCS telephone docking apparatus by the PCS telephone user in step 310. This will start the charging process for the PCS telephone battery, but also enables the user to receive incoming PCS telephone calls with the wireless local area telephone interfaced with the telephone docking apparatus.

In step 315, the PCS telephone receives an incoming call signal from a PCS network at the base station. At step 320, a representation of an incoming call is provided to the docking apparatus 200 through the interface 101. At step 325, modules within the docking apparatus, in response to the receiving the representation of the incoming call converts the call to an outgoing call signal to the wireless local area telephone. At step 330, the user receives the incoming call on the wireless local area telephone. Preferably, the conversion and transfer/relay processes are seamless to the user, who, in step 335, answers the telephone call using the wireless local area telephone to conduct a telephone conversation.

Step 345 indicates that the PCS telephone has received a visual message, such as a text message. At step 350, a representation of the text message has been provided to the connector of the docking apparatus. At step 355, the representation of the text message has been detected by the docking apparatus and provided to a local display associated with the docking apparatus, or the wireless local area telephone.

A specific advantage of the embodiment described herein is that when a user wishes to charge a battery in their PCS telephone, they are still able to receive and make calls using their PCS phone by physically using the wireless local area telephone in lieu of the PCS telephone. A process of initiating calls from the wireless local area telephone is presented in FIG 4. A flow diagram illustrating a method of relaying PCS telephone calls from a wireless local area telephone to a wireless wide area network telephone, such as a PCS telephone, is disclosed.

In step 410, a user places a PCS telephone in the PCS telephone docking apparatus. The user removes the wireless local area telephone from the docking apparatus/charger and dials a number, either on the keypad of the cordless telephone, or on the alphanumeric keypad of the PCS telephone docking apparatus. In response to the number input, an outgoing call signal is initiated from the cordless telephone, as in step 415. In step 420, the outgoing call, after being received at the docking station, provides a representation of the outgoing call to the PCS telephone via an interface, such as interface 101 of FIG.2. At step 425, the PCS telephone transmits a representation of the outgoing call using the PCS transmission protocol. Finally, in step 430, the user utilizes the wireless local area telephone to make the PCS telephone call, since relaying continues until an off-hook signal is received from the user of the cordless telephone, e.g., the user presses the "Off or "End" key on the wireless local area telephone to terminate the call.

As with incoming text messages from the PCS telephone, the telephone docking apparatus may also be utilized to relay outgoing text messages in a similar fashion to that of sending an outgoing call signal. Outgoing text messages would typically be displayed in the visual display window of the PCS telephone docking apparatus as part of the process of being relayed to the PCS telephone for transmission via a wireless wide area network. The wireless wide area network telephone apparatus is also capable of transferring images to or from an image-capable PCS telephone via various interfaces, as discussed in conjunction with steps 445-455 of FIG. 4.

At step 445, the user initiates the transfer of an outgoing image or text from the wireless local area telephone, or a peripheral device, such as a camera or general purpose computer, that is coupled to an interface port, such as a USB port. At step 450, the image or text, is provided to the image-capable PCS telephone for display, storage or transmission. In a particular embodiment, the external device is a personal computer. In other embodiments, the external device may be a personal data assistant, a camera, or another storage device such as a personal data assistant (PDA). At step 455, a communication signal can be transmitted to the image capable PCS telephone to facilitate transmitting the image or text to another device, which may be another image capable PCS telephone.

The apparatus and methods described herein provides for a flexible implementation. Although embodiments of the invention have been described using certain specific examples, it will be apparent to those skilled in the art that the invention is not limited to these few examples. Additionally, various types of PCS telephones and cordless telephones are currently available which could be suitable for use in the docking apparatus for relaying PCS communications when employing the methods and apparatus as taught herein.
