ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates in general to communication systems such as voice paging systems, cellular telephone systems, text paging systems, voice mail systems, and conventional land line telephone systems and, more specifically, to methods, systems and apparatus for non-real-time audio and visual messaging between two messaging devices wherein a communication device receives visual messages from a visual message originator device and transmits audio messages (e.g., voice messages) to the visual message originator device for playback.
2. Discussion of the Background
A conventional mobile communication device (MCD), such as a pager or a mobile telephone, can receive various types of messages. There are numeric pagers which receive only numbers such as a telephone numbers (i.e. 818-555-1212), and there are alpha
umeric pagers which can receive alpha
umeric messages (e.g., Please call me at 929-555-1212). Additionally, there are voice pagers which receive voice messages. In addition to receiving messages, pagers are often configured to transmit messages. An alpha
umeric pager may be configured to receive alpha
umeric messages from an Internet-based computer and to transmit to the Internet-based computer originator alpha
umeric reply messages. Similarly, a voice pager that receives voice messages from a telephone-based originator can be configured to transmit a voice message to a voice mail system for retrieval by the originator via a telephone. In short, alpha
umeric pagers are configured to transmit alpha
umeric reply messages and voice pagers are configured to transmit voice reply messages.
In the field of wireless messaging generally, numeric and alpha
umeric messaging is, by far, more bandwidth efficient than voice messaging. Radio spectrum is a dwindling resource and wireless messaging companies are increasingly sensitive to their bandwidth efficiencies. Better bandwidth utilization means more capacity on the system. More capacity equates to more customers. Hence, the wireless messaging industry has migrated from voice paging to alpha
umeric paging in order to provide a bandwidth efficient, robust and high information content messaging service for their so called “road warrior” customers.
However, to date, there is no simple method for sending a message containing more than a small amount of information from an alpha
umeric pager. Generally, alpha
umeric pagers that have the ability to send messages are configured to transmit small, pre-programmed (“canned”) text messages, such as “I will call you tonight” or “yes” or “no” or “I will reply later.” Other alpha
umeric pagers have been configured with a miniature, QWERTY type, text keyboard. The miniature keyboards are difficult to type on because of their size. This makes input very slow, inaccurate and very annoying to operate. Additionally, the miniature size of the keyboard is still too large for a pocket-sized pager.
Audio pagers are generally larger than keyboardless alpha
umeric pagers, in part because of the large speaker required in order to reproduce a high quality, audible audio message. An audio pager's battery life is lower than an alpha
umeric pager due to the amount of time it takes to receive a message and the amount of power required to process and play the message.
One solution to the above problem is to route a mobile telephone originated voice reply message to a computer. However, it's simply not convenient to send a voice message via a mobile telephone, configure a computer to receive a voice reply message and then mentally correlate the sent and received messages together (i.e. Was the reply “sounds good to me” meant to be an answer to the message, “I will pay $140,000.00 for your home” or “lets have lunch tomorrow at the fish place”).
A need, therefore, exists to blend audio (e.g., voice) and visual (e.g., text and/or graphics) messaging in a manner that conserves valuable bandwidth and simplifies user input of messages in a mobile communication device. An attempt to that end, is the so-called “smart phone.” Smart Phones are wireless mobile telephones that have added features, implying that they are smarter than the average telephone. These features may include a numeric and alpha
umeric messaging feature, a personal digital assistant (PDA), computer functions, Internet access, and a miniature keyboard. Similar to an alpha
umeric pager, many mobile telephones today are capable of receiving alpha
umeric messages and have the capability of connecting to the Internet for sending alpha
umeric reply messages via a miniature keyboard. There is a need to simplify the input of reply messages into wireless devices for delivery of the reply messages to the originating device, wherein both messages may be correlated.
In an alpha
umeric pager messaging environment, text messages are routinely exchanged between a computer and a text pager (i.e. text in/text out). In a voice pager messaging environment, voice messages are routinely exchanged between a telephone configured voice mail system and a voice pager (i.e. voice in/voice out). In a mobile telephone messaging environment, as with an alpha
umeric pager, text messages routinely are exchanged in non real-time (i.e. text in/text out). However, mobile telephones also have the ability to make and receive real-time voice calls. More often than not, when a mobile telephone user receives a text message requiring some type of response, he or she will simply use the mobile telephone to place a real-time telephone call to the message originator. In many cases, the line is busy because the originator is either on the phone or connected to the Internet. In either case, the mobile caller is diverted to a voice mail system or answering device and is instructed to leave a message, which is then retrieved by the called person at a later time.
Many people prefer to communicate by messaging as opposed to real-time conversation in order to manage their time. Thus, there is a need for a device that can not only send non real-time text messages, but also receive non real-time voice messages (i.e. text out/voice in). At the wireless side of the messaging loop, there is a need to send non real-time voice messages from the same mobile device that receives non real-time text messages (i.e. text in/voice out).
It is widely accepted in the field of two way paging, that only a fraction of received messages generate a reply message response. On the other hand, when text message reception capability is combined with a mobile telephone, the mobile telephone user will attempt to reply much more often via a real-time voice call. Mobile telephone companies call this process “call completion” and it is highly favored among mobile telephone companies because additional calling generates more revenue. There is a need to increase reply traffic in a wireless environment without decreasing the efficiency of text message delivery to a mobile communication device. There is also a need to simplify the input of messages in a mobile communication device, such as a pager or wireless mobile telephone. Finally, there is a need for a wireless messaging system that provides end to end audio and visual messaging, wherein only one device is required at each end of the messaging loop (e.g., computer on the one end and mobile communication device on the other).
SUMMARY OF THE INVENTION
The present invention provides a communication system for integrating audio and visual messaging. The communication system includes a communication device for receiving visual messages and for transmitting voice messages to a recipient, and an integrated mail gateway for receiving from the communication device a voice message and addressing information. The integrated mail gateway is programmed to create an electronic mail (hereinafter “e-mail”) message comprising the voice message. The integrated mail gateway is also programmed to use the addressing information to address the e-mail message, and to send the addressed e-mail message to the recipient
