## Background
BACKGROUND
1. Field of Invention
The present invention relates to telephones and, more particularly, to the transmission of digital images from a telephone.
2. Description of Related Art
Advancements in camera technology have made digital cameras an increasingly popular alternative to conventional film-based cameras. Digital cameras do not require film to capture images. Instead, digital cameras capture images by allowing light to pass through a series of lenses to focus the light at an image sensor. The image sensor is a semiconductor device that captures an image electronically as an array of pixels. A pixel is the smallest picture element of a digital image. A digital camera produces a digital representation of each pixel and stores the digital representation of each pixel in a storage medium such as a flash memory card. Digital cameras may include a liquid crystal display (LCD) screen that allows a user to immediately view images captured by the image sensor without having to develop film as required with film-based cameras.
Advancements have also been made in telephone system technology. In a conventional land-line telephone system employing circuit switching, a conventional land-line telephone provides a means to perform voice communication with a user at another device. Circuit switching is a switching system that establishes a dedicated physical communication connection between end points, through a network, for the duration of a communication session. A conventional land-line telephone is coupled to a local exchange carrier's central office via local loop telephone lines and performs voice communications by sending and receiving analog signals via the local loop telephone lines. Coupling modems to a sending site and a receiving site in a conventional land-line telephone system is a means for sending and receiving digital data via the local loop telephone lines.
Further, conventional land-line telephones can be used to call a gateway that performs packet switching to communicate with another device. Packet switching is a switching system that establishes a physical communication connection only long enough to send/receive data packets via a network, where the data packets may travel over many diverse communication links to get to a common endpoint. One advantage of packet switching is that it can increase the communication capacity of a network as compared to a network that uses circuit switching. Packet switching technologies have led to the development of telephones (e.g. Internet Protocol telephones) that perform packet switching directly without the need to call a gateway.
Another more recent advancement in telephone system technology is the development of wireless telephones and wireless networks to provide voice and data communications from a wireless telephone to another device. A wireless telephone and wireless network provide a wireless telephone user with mobility to communicate with another device while the user moves from one location to a second location. Wireless telephones and wireless networks may employ packet switching technologies.
Modern camera technology has recently been integrated with modern telephone system technology to allow integrators to produce and market camera phones. Camera phones are a combination of a digital camera and a wireless phone. Camera phones allow for capturing images, wireless transmission of those images over a data network to a remote location, and a variety of other functions.
Methods of transmitting a digital image from a camera phone over a data network to a remote location are well known. One such method involves a camera phone establishing a packet session with a packet data serving node (PDSN) via a radio access network and sending packets of data representing (i) a captured image, and (ii) a destination identifier, via the PDSN to a network server.
A destination identifier comprises information from which a destination may be ascertained. A destination identifier could take the form of an e-mail address which represents a destination such as network server that performs e-mail functions for an account associated with the e-mail address. Alternatively, a destination identifier could take the form of a mobile identification number (MIN) which represents among other things, a destination such as a remote camera phone operating under the MIN. Other types of destination identifiers are also possible.
A network server that receives a destination identifier along with a digital image may use the destination identifier to facilitate sending the digital image to the destination represented by the destination identifier. A party with access to the destination may view the digital image sent to the destination.
Another camera phone function involving digital images is photographic caller identification. Photographic caller identification occurs by identifying the phone number of the calling phone, identifying an image associated with the phone number, and displaying the image during the phone call. Photographic caller identification thus allows a camera phone user to view an image associated with the phone number of a calling phone.
Yet another camera phone function involving digital images is photographic phone book display. Photographic phone book display is an alternative or supplement to more traditional methods of displaying a personal phone book such as a list of phone numbers, names, or memory locations. Photographic phone book display occurs by displaying images assigned to phone numbers. A phone number is selected for dialing by identifying and selecting the image associated with the phone number to be dialed. Photographic phone book display may also display the selected image during an outgoing phone call to the dialed phone number.
SUMMARY
The present invention provides a method and apparatus for transmitting a digital image correlated with a phone number to a called party during a voice call with the phone number. The called party could comprise a destination, such as an e-mail address associated with the called phone number.
In one respect, an exemplary embodiment of the invention may take the form of a method that includes the functions of (i) maintaining, in a telephone, data that correlates phone numbers with digital images, (ii) placing a voice call between the telephone and a party at a phone number, (iii) using the data to identify a digital image correlated with the phone number, and (iv) sending the digital image to the party.
In another respect, the exemplary embodiment may take the form of a method that includes the functions of (i) maintaining, in a telephone, data that correlates phone numbers with digital images, (ii) placing a voice call between the telephone and a phone number, (iii) using the data to identify a digital image correlated with the phone number, and (iv) sending the digital image from the telephone into a network, for transmission of the digital image via the network to a destination associated with the phone number. In this exemplary embodiment, the functions of (i) using the data to identify an image, and (ii) sending the digital image into the network, may occur in response to placement of the voice call.
Further, the function of sending the digital image from the telephone into the network for transmission of the digital image via the network to a destination may include sending the digital image to a network server via a packet-data connection. One way of sending the digital image to the network server via the packet-data connection includes sending the digital image via a cellular communication module to a radio access network for transmission of the digital image to the network server.
Additionally, this method could include sending a destination identifier together with the digital image to the network server, when sending the digital image into the network, to facilitate transmission of the digital image via the network to the destination. The destination identifier may take the form of a phone number, an e-mail address, or some other form.
In yet another respect, the exemplary embodiment could take the form of an apparatus that includes a communication interface for sending and receiving communications, a processor, program-logic executable by the processor, and data storage for storing the program-logic. In this exemplary embodiment, execution of the program-logic includes executing logic to (i) detect placement of a voice call between the telephone and a phone number, (ii) identify a digital image that has been correlated with the phone number, and (iii) send the digital image into a network for transmission of the digital image to a destination associated with the phone number. Execution of the program-logic to identify and send the digital image may occur in response to detecting placement of the voice call between the telephone and the phone number.
Execution of the program-logic in the exemplary embodiment may also involve (i) referring to data, in data storage, that correlates digital images with phone numbers in order to identify a digital image correlated with a phone number, and (ii) automatically sending the digital image into the network. Referring to data may include searching the data that correlates digital images with phone numbers.
In still yet another respect, the exemplary embodiment could take the form of an apparatus such as a wireless camera phone that includes (i) means for capturing digital images, (ii) means for storing digital images, (iii) means for correlating the stored digital images with phone numbers, (iv) means for placing voice calls, and (v) means for detecting placement of a voice call between the wireless camera phone and a given phone number, responsively correlating the given phone number with a given digital image of the stored digital images, and sending the given digital image into a network for transmission in turn to a destination associated with the given phone number. In this exemplary embodiment, the destination could include a remote telephone operating under the given phone number or an e-mail address derived from the given phone number.

2. Exemplary Architecture
a. Wireless Network Architecture
FIG. 2 provides an overview of a system for carrying out the present invention. It should be understood, however, that this and other arrangements described herein are for purposes of example only. As such, those skilled in the art will appreciate that other arrangements and other elements (e.g. machines, interfaces, functions, orders, and groupings of functions, etc.) can be used instead, and some elements may be omitted altogether. Further, many of the elements described herein are functional entities that may be implemented as discrete or distributed components or in conjunction with other components, in any suitable combination and location.
The system of FIG. 2 includes a first wireless device 120 which is arranged to communicate over a radio frequency (RF) air interface 122 with a base station 124. The first wireless device 120 may comprise a wireless camera phone. The base station 124 includes (i) a base transceiver station (BTS) 126 having an antenna for communicating with the first wireless device 120, and (ii) a base station controller (BSC) 128 which controls communication with the BTS 126.
A second wireless device 130 may also communicate with base station 124 via an RF air interface 132. The second wireless device 130 may also comprise a wireless camera phone. The first wireless device 120 and the second wireless device 130 may communicate with each other by way of base station 124 and RF air interfaces 122 and 132.
Further, the BSC 128 is coupled to a switch or gateway such as a packet data serving node (PDSN) 134 or a first mobile switching center (MSC) 136. A RAN includes the coupling mechanisms leading to various switches and gateways, along with the base station 124, and an air interface such as air interface 122.
The PDSN 134 acts as a gateway to a packet-switched network 138 operating as a wireless carrier's core network. The packet-switched network 138 may be coupled to a plurality of devices. For instance, the packet-switched network 138 may be coupled to a server 140, which in turn is coupled to data storage 142. Data storage 142 may store user messages and other types of data for the wireless carrier's customers.
Another example of a device that may be coupled to packet-switched network 138 is a firewall 144. The firewall 144 may perform network address translation (NAT) functions to allow packet-switched network 138 to communicate via another network such as a packet-switched network 146. An example of packet-switched network 146 is the Internet.
A plurality of devices may be coupled directly or indirectly to the packet-switched network 146. For instance the packet-switched network 146 may be coupled to a server 148, which in turn is coupled to a plurality of devices that access the packet-switched network 146 via the server 148. Examples of devices accessing the packet-switched network 146 via the server 148 include an Internet Protocol (IP) telephony device 150 and a personal computer 152.
The first MSC 136 performs switching functions for making connections to a PSTN 154. PSTN 154 may be coupled to a variety of devices such as a central office switch 156, located at a local exchange carrier's central office, and a second MSC 158. A local loop telephone line 160 extends from central office switch 156 to a junction box at a customer's premises 162. Additional telephone lines may be used to couple local loop telephone line 160 to a plurality of customer premises equipment such as a modem 164, a personal computer 166, and a landline phone 168.
The second MSC 158 is coupled to a base station 170 that includes a base station controller (BSC) 172 and a base transceiver station (BTS) 174. BSC 172 controls communications for BTS 174, which includes an antenna for communicating with a third wireless device 176. The third wireless device 176 may comprise a wireless camera phone. Communications between BTS 174 and the third wireless device 176 occur via an RF air interface 178.
b. Wireless Camera Phone Architecture
FIG. 3 depicts a simplified block diagram of an exemplary telephone in the form of a wireless camera phone 200 for carrying out the present invention. The wireless camera phone 200 includes an image capture segment 202, data storage 204, a processor (i.e., one or more processors) 206, and a communication interface 208, all linked together via a system bus, network, or other connection mechanism 210. The first wireless device 120, the second wireless device 130, and the third wireless device 176 shown in FIG. 2 may each be arranged as the wireless camera phone 200.
The image capture segment 202 provides means for capturing digital images at the wireless camera phone 200. Preferably, the image capture segment 202 will include features typically available in a digital camera, such as a lens for focusing light from a subject being photographed, a light source for illuminating the subject, and a device for (i) detecting light from the subject, (ii) converting light to an array of electrical charges, and (iii) storing an array of values representing the array of electrical charges.
The image capture segment 202 may include an image sensor with light sensitive diodes for converting light into electrical charges. Commonly used images sensors include charge coupled device (CCD) image sensors and complementary metal oxide semiconductor (CMOS) image sensors. The image capture segment 202 may also include an analog-to-digital converter to convert the value of each electrical charge into a digital value.
The image capture segment 202 may then work cooperatively with processor 206 to (i) send an array of digital values representing the digital image to processor 206 for storage at data storage 204, or (ii) send the array of digital values directly to data storage 204. The processor 206 may execute image-capturing program-logic stored at data storage 204 to capture the digital image and store the digital image at data storage 204. As an alternative to the image capture segment 202 described above, the image capture segment 202 could comprise an optical scanner device or some device suitable for capturing digital images.
Data storage 204 provides means for storing various forms of data such as digital images, phone numbers, program-logic executable by the processor 206, and data correlating digital images with phone numbers. Data storage 204 (i.e., one or more segments of data storage) may be arranged in a variety of ways. For example, data storage 204 may include a segment of data storage integrated with the processor 206 and/or a segment of data storage arranged as removable data storage. Data storage 204 may also include other segments of data storage as well. Exemplary segments of removable data storage include (i) a compact flash memory card, (ii) a memory stick device, and (iii) a secure digital (SD) memory device.
Preferably, data storage 204 comprises computer readable medium that may include any volatile memory and/or non-volatile memory readable by the processor 206. An example of volatile memory is Random Access Memory (RAM) and an example of non-volatile memory is Electronically Erasable Programmable Read Only Memory (EEPROM). Non-volatile memory is preferred because non-volatile memory retains stored data even when power is removed from the non-volatile memory.
The processor 206 may comprise one or more processors (e.g. parallel processors), such as a general purpose microprocessor and/or a digital signal processor. The processor 206 works cooperatively with the image capture segment 202, data storage 204, and the communication interface 208 to perform various functions, in part, by executing program-logic stored at data storage 204.
The program-logic stored at data storage 204 and executable by the processor 206 may include a variety of logical instructions. Examples of logical instructions include instructions for (i) detecting placement of a voice call between the wireless camera phone 200 and a party at a given phone number, (ii) detecting placement of a voice call between the wireless camera phone 200 and a given phone number, (iii) correlating a digital image stored in data storage 204 with a given phone number stored in data storage 204, (iv) identifying a stored digital image correlated with a given phone number, and (v) sending the digital image from the wireless camera phone 200 to a called party.
Execution of logical instructions to detect placement of a voice call between the wireless camera phone 200 and a party at a given phone number or a given phone number could occur in a variety of ways. First, detecting placement of the voice call by executing logical instructions could include the processor 206 detecting initiation of the voice call. Detecting initiation of the voice call could occur by the processor 206 detecting that the wireless camera phone 200 sent a call origination message, that provides the given phone number as dialed digits, into a network. Second, detecting placement of the voice call by executing logical instructions could include the processor 206 detecting that the wireless camera phone 200 is currently engaging in a voice call and that the voice call is between the wireless camera phone 200 and a party at a given phone number or a given phone number. Other ways of detecting placement of the voice call by executing logical instructions are also possible.
Execution of program-logic to correlate a digital image stored in data storage 204 with a given phone number stored in data storage 204 may include the processor 206 creating correlation-data. Creating correlation-data could include the processor 206 combining a reference to a data image and a reference to a phone number to form the correlation-data. The reference to the data image could indicate the memory addresses of the data image and the reference to the phone number could indicate the memory addresses of the phone number and/or the phone number itself. The processor 206 could send the correlation-data to data storage 204 in order to store the correlation-data. Other ways of creating correlation-data are also possible. Examples of correlation-data are shown in FIG. 4.
Execution of program-logic to identify a stored digital image correlated with a given phone number could involve the processor 206 reading the correlation data, comparing the correlation data to the given phone number to find the given phone number in the correlation data, and then reading the correlation data to identify a stored digital image correlated with the given phone number. The processor 206 could execute the program-logic to identify a stored digital image in response to the wireless camera phone 200 detecting placement of the voice call between the wireless camera phone 200 and a given phone number.
Execution of program-logic to send the digital image from the wireless camera phone 200 to the called party facilitates transmission of the digital image to a called party. Execution of the program-logic to send the digital image may involve sending the digital image in a variety of ways. First, execution of the program-logic to send the digital image may comprise the processor 206 instructing the communication interface 208 to send the digital image from the wireless camera phone 200 to the called party during initiation of the voice call, during the voice call, or after the voice call has ended. Second, execution of the program-logic to send the digital image may comprise the processor 206 instructing the communication interface 208 to send the digital image into a network for transmission of the digital image to a destination associated with the phone number. Third, execution of the program-logic to send the digital image may comprise the processor 206 instructing the communication interface 208 to send the digital image into the network in response to the wireless camera phone 200 detecting placement of the voice call with a given phone number.
Exemplary networks that may receive the digital image sent by the wireless camera phone 200 include (i) a RAN, (ii) a packet-switched network operated by a wireless carrier, such as the packet-switched network 138 shown in FIG. 2, (iii) a packet-switched network, such as packet-switched network 146 shown in FIG. 2, and (iv) a PSTN, such as PSTN 154 shown in FIG. 2. Other types of networks are also possible for receiving the digital image.
A variety of exemplary destinations associated with a given phone number are possible. For instance a destination associated with a given phone number may be a remote device such as the third wireless device 176, the landline phone 168, the IP telephony device 150, or the server 148, all of which are shown in FIG. 2. Also, the destination associated with a given phone number could be an address of a remote device such as (i) an e-mail address, (ii) a Session Initiation Protocol (SIP) address, or (iii) an Internet Protocol (IP) address. A destination that takes the form of an address may possibly be derived from the given phone number. For example an e-mail address may be derived from a given phone number by searching a data base for the given phone number and finding the e-mail address correlated with the given phone number. The data base could be located in a network device such as at data storage 142 or could be in the wireless camera phone 200, such as in data storage 204.
Execution of the program-logic by the processor 206 may also include sending a destination-identifier with the digital image. Examples of destination-identifiers include phone numbers, e-mail addresses, SIP addresses, and IP addresses. By way of example, processor 206 may direct communication interface 208 to send a SIP address of an IP telephony device, such as IP telephony device 150, along with a digital image into a network. Destination identifiers facilitate sending a digital image to a destination by indicating the destination to a device, remote from the wireless camera phone 200, that will participate in sending the digital image to the destination.
The communication interface 208 provides means for sending and receiving communications. The communications interface 208 may send communications to other portions of the wireless camera phone 200, such as the processor 206, via the system bus 210, and to an entities external to the wireless camera phone 200. Also, the communications interface 208 may receive communications from other portions of the wireless camera phone 200, such as the processor 206, via the system bus 210, and from an entities external to the wireless camera phone 200.
Sending communications to the entities external to the wireless camera phone 200 and receiving communications from the entities external to the wireless camera phone 200 may occur via an air interface, such as air interface 122 shown in FIG. 2, or by coupling the wireless camera phone 200 to a network, such as the packet-switched network 146 via the server 148, both shown in FIG. 2.
Examples of the communications that could be received by the communications interface 208 from other portions of the wireless camera phone include a message instructing the communications interface 208 to place a voice call and a message instructing the communications interface 208 to send a digital image.
Examples of the communications that could be sent by the communications interface 208 to other portions of the wireless camera phone include a message to the processor 206 indicating that the communications interface 208 has placed a voice call in response to a message instructing the communication interface 208 to place the voice call, and a message to the processor 206 indicating that the communications interface 208 sent a digital image into a network. Other communications between the communications interface 208 and other portions of the wireless camera phone 200 are also possible.
Examples of the communications that could be received by the communications interface 208 from the entities external to the wireless camera phone 200 include messages that an incoming voice call is available and messages that a digital image has been received by the called party.
Examples of the communications that could be sent by the communications interface 208 to the entities external to the wireless camera phone 200 include (i) a digital image, (ii) a destination identifier, (iii) messages to originate a voice call between the wireless camera phone 200 and a given phone number, and (iv) messages for negotiating with a PDSN to secure a packet-data connection, such as a point-to-point protocol (PPP) link.
In response to the wireless camera phone 200 negotiating with a PDSN to secure a packet-data connection, the PDSN may assign an identification number such as a mobile IP address to the wireless camera phone 200. Upon establishing the packet-data connection, the communication interface 208 may send the processor 206 a message indicating that a secure packet-data connection has been made. The processor 206 may respond by sending one or more messages to the communications interface 208 instructing the communications interface 208 to send a digital image to a destination associated with a given phone number. The processor 206 may execute program-logic to automatically send the digital image to a network server via the packet-data connection.
The communication interface 208 of wireless camera phone 200 comprises a wireless interface, such as a cellular communication interface and/or a satellite communication interface. The processor 206 may execute program-logic stored at data storage 204 in order to send a digital image, via the cellular communication interface, to a RAN, for further transmission of the digital image to a network server.
A cellular and/or satellite communication interface may include a chipset and antenna for interfacing with a RAN via an established air interface protocol. An exemplary air interface protocol is the Code Division Multiple Access (CDMA) protocol. Other air interface protocols such as Time Division Multiple Access (TDMA), Advanced Mobile Phone System/Service (AMPS), and Global System for Mobile Communications (GSM) are examples as well. An exemplary chipset that facilitates air interface communication according to the CDMA protocol is the MSM6000TM chipset manufactured by Qualcomm Incorporated of San Diego, Calif.
The communication interface 208 may also include an interface for coupling to a network, such as the packet-switched network 146 shown in FIG. 2, by coupling to a server, such as server 148 shown in FIG. 2. An example of an interface for coupling to a network is an Ethernet network interface card.
The combination of the image capture segment 202, the data storage 204, the processor 206, and the communication interface 208, provide means for (i) capturing digital images, (ii) storing digital images, (iii) correlating the stored digital images with phone numbers, (iv) placing voice calls, and (iv) detecting placement of a voice call between the wireless camera phone 200 and a given phone number. In response to detecting placement of the voice call, the combination of the image capture segment 202, the data storage 204, the processor 206, and the communication interface 208, provide means for correlating the given phone number with a given image of the stored images, and transmitting the image into a network for transmission to a destination associated with the given phone number.
c. Data Storage Architecture
Data storage, such as data storage 106 shown in FIG. 1 and data storage 204 shown in FIG. 3, provides means for storing various forms of data, such as digital images, phone numbers, data correlating digital images with phone numbers, and destination identifiers associated with a given phone number. Data storage may also store other types of data. FIG. 4 is a simplified block diagram depicting exemplary blocks of data that may be stored at data storage 204 in the exemplary wireless camera phone 200.
In FIG. 4, data storage 204 includes various blocks of data including a phone number block 302, an image-file block 304, a destination-identifier block 306, and a correlation-data block 308. Data storage 204 may include additional or fewer blocks of data to store digital images, phone numbers, data correlating digital images with phone numbers, and destination identifiers. Data storage 204 may also store data in other and/or additional ways.
A block of data could include a single set of consecutive memory addresses within data storage 204 or more than one set of consecutive memory addresses within data storage 204 where there are intervening memory addresses between the more than one set of consecutive memory addresses.
The phone number block 302 is shown to include a first phone number (555-0001) 310, a second phone number (555-0002) 312, a third phone number (555-0003) 314, and a fourth phone number (555-0004) 316. Each phone number stored in the phone number block could be a number of digits less than, greater than, or equal to the seven digits shown representing the first, second, third, and fourth phone numbers 310, 312, 314, 316.
Further, the first, second, third, and fourth phone numbers 310, 312, 314, 316 may be stored in the phone number block 302 using a standard code. An exemplary standard code is the American Standard Code for Information Interchange (ASCII) standard which is a standard for representing certain alphanumeric characters and non-alphanumeric characters, such as “−”, “@”, and “+”, with a seven bit binary number ranging from 0000000 to 1111111. Alternatively, or in addition to a standard code, the first, second, third, and fourth phone numbers 310, 312, 314, 316 may also be stored using a non-standard code, such as an application specific code.

FIG. 5 is a flow chart provided to illustrate some of the functions that could be carried out in accordance with the exemplary embodiment. The functions shown in FIG. 5 could occur in a sequence from top to bottom as shown in FIG. 5 or in another sequence.
Block 350 involves creating data that correlates phone numbers with digital images. Creating the data that correlates phone numbers with digital images may occur in various ways. Creating the data that correlates phone numbers with digital images could involve processor 206 executing program-logic to correlate a digital image with a phone number, as described above with respect to the wireless camera phone architecture.
Creating the data that correlates phone numbers with digital images could also include a telephone user selecting a digital image stored in data storage 204 and then entering a phone number, or a telephone prompting the telephone user to enter a phone number immediately upon the telephone capturing a digital image. Entering a phone number could occur in a variety of ways such as speaking the phone number, speaking a voice tag associated with the phone number, pressing telephone buttons to enter the phone number, or selecting a phone number from a list of phone numbers stored in data storage 204.
After the data has been created at Block 350, Block 352 involves maintaining the data that correlates phone numbers with digital images. Maintaining the data that correlates phone numbers with digital images could occur in a variety of ways. For example, maintaining the data could involve storing the data in data storage 204 after creation of the data, as well as continuing to store the data in data storage 204 after the digital image has been sent to the called party.
Maintaining the data could also involve arranging the data in data storage 204 in such a way that the data may be searched after storing the data in data storage 204. The correlation-data block 308 shown in FIG. 3 is an example of arranging data as sets of correlation-data so that a processor 206 can search distinct sets of data that correlate a phone number and a digital image. A processor searching distinct sets of data could involve a processor 206 reading the first, second, third, and fourth sets of correlation-data 330, 332, 334, 336 and identifying a sets of correlation-data for a given phone number, such as the first set of correlation data 330 that includes the first phone number (555-0001) 310 and the first image 318.
Block 354 involves placing a voice call between the telephone and a called party. The called party could comprise a given phone number. Also, the called party could comprise a party that uses a remote device, such as a remote telephone, suitable for participating in voice calls. The remote device could comprise a device operating under the given phone number.
The remote device operating under the given phone number could be a remote device coupled to a local loop telephone line which is assigned the given phone number. A local exchange carrier operating a central office switch coupled to the local loop telephone line is typically responsible for assigning the given phone number to the local loop telephone line. Alternatively, the remote device operating under the given phone number could be a remote device that has been programmed with the given phone number, such as a mobile identification number (MIN), and registered with a mobile switching center, such as MSC 136, in order to participate in voice calls. Other ways that a remote device can operate under the given phone number are also possible.
Placing the voice call between the telephone 100 and the called party could include the telephone 100 producing dual-tone multi-frequency (DTMF) tones recognizable by a central office switch, such as central office switch 156, and the central office switch functioning with a network, such as the PSTN 154, to set up the voice call between the telephone 100 and the called party.
Alternatively, placing the voice call between the telephone (wireless camera phone 200) and the called party could include the wireless camera phone 200 initiating the voice call by sending a call origination message that includes dialed digits representing the given phone number to a base station, such as base station 124, and the base station forwarding the call origination message to a mobile switching center which functions to set up the voice call between the wireless camera phone 200 and the called party. Other ways of placing a voice call between the telephone and the called party are possible.
Block 356 involves detecting placement of the voice call between the telephone and the called party. Detecting placement of the voice call could occur in a variety of ways. For example, detecting placement of the voice call could occur by executing logical instructions to detect placement of the voice call as described above with respect to the exemplary wireless camera phone architecture.
Alternatively, processor 206 could detect placement of a voice call to the called party by detecting execution of logical instructions to perform speech recognition of a speech command to initiate a voice call between the telephone and the called party. Examples of speech commands that could be recognized to initiate a voice call include commands such as speaking the name of the called party, or speaking “call” or “dial” immediately prior to speaking a phone number of the party to be called. Other speech commands that could be recognized to initiate a voice call between the telephone and the called party are also possible.
Additionally, the telephone 100 could detect placement of a voice call between the telephone 100 and a called party by the processor 104 detecting that telephone 100 sent DTMF tones to the central office switch in order to initiate placement of the voice call between the telephone 100 and the called party. In this regard, the DTMF tones represent the phone number of the given party. Other ways of detecting placement of the voice call between the telephone 100 and the called party are also possible.
Next at block 358, a digital image correlated with a phone number is identified by using data that correlates the phone number with the digital image. The function of using data that correlates phone numbers with digital images to identify a digital image with a phone number could include processor 206 reading and comparing the data to find a digital image correlated with a given phone number. Processor 206 could read and compare the data by executing logical instructions.
By way of example, a digital image correlated with a phone number could be identified by using data that correlates phone numbers with digital images by (i) the processor 206 executing logical instructions in order to read the first set of correlation-data 330 stored in the correlation-data block 308, (ii) the processor 206 executing logical instructions to compare the first phone number 310 of first set of correlation-data 330 to the phone number of the called party, and (iii) the processor 206 executing logical instructions to read the first set of correlation-data 330 to identify a digital image correlated with the phone number if the first phone number 310 matches the phone number of the called party. Other examples of using data that correlates phone numbers with digital images to identify a digital image correlated with a phone number are also possible.
Next, Block 360 involves sending the digital image from the telephone to the called party. Sending the digital image from the telephone to the called party could involve the execution of program-logic by processor 206 to send the digital image from the wireless camera phone 200 to the called party, as described above with respect to the exemplary wireless telephone architecture.
Execution of program-logic for sending the digital image from the telephone to the called party could also include executing instructions for sending the digital image, via a packet-data connection, to a network server, such as server 140. Sending the digital image via the packet-data connection may comprise the telephone negotiating with a PDSN, such as PDSN 134, to set up a link, such as a point-to-point protocol (PPP) link, between the telephone and the network server 140. After the telephone secures a packet-data connection and sends the digital image to the network server 140, the network server 140 may then transmit the digital image to the called party.
Sending the digital image from the telephone to the called party could also involve sending the digital image from the telephone to a destination associated with the called party. A destination associated with the called party could be a location remote from the called party or a location co-located with the called party. Examples of destinations associated with the called party include an address such as an e-mail address, a SIP address, an IP address, and a device remote from the telephone. Examples of devices remote from the telephone include (i) a first remote telephone that operates under a first phone number, where placement of the voice call is between the telephone and the first phone number, (ii) a second remote telephone that operates under a second phone number, and (iii) a server capable of receiving digital images.
Sending the digital image from the telephone to the called party could also involve the telephone deriving the destination associated with the called party from the phone number of the called party. Deriving the destination associated with the called party could involve the telephone searching data that correlates phone numbers with destinations, such as correlation data 308, and determining a destination associated with a phone number of the called party. For example, the telephone could search the correlation-data 308 for the first phone number (555-0001) 310 and derive a destination associated with the first phone number 310 by reading the first set of correlation data 330 that includes the first phone number 310 and the first destination identifier (john.doe@email.com) 324. Deriving a destination associated with the called party could also occur in a network device, such as a server, after the telephone sends the digital image and data representing the telephone number of the called party into the network for transmission to the network device.
Furthermore, sending the digital image from the telephone to the called party could involve the telephone sending a destination identifier along with the digital image. The destination identifier facilitates a network and/or a remote device, such as a network server, in sending the digital image to the called party, by informing the network and/or remote device where to send the digital image. Examples of destination-identifiers include a phone number of a remote telephone, an e-mail address, a SIP address, and an IP address. Other exemplary destination identifiers are also possible.
