1. Technical Field
The invention disclosed herein generally relates to a method for transmitting a message from a telephone caller to a telephone call recipient, wherein message transmission takes place during the call set up procedure. More particularly, the invention relates to a method of the above type wherein the message is defined by a sequence of alphanumeric characters that are pressed, dialed or otherwise entered using the caller's phone, just prior to entering the recipient's phone number.
2. Description of Related Art
It is very common for a person to receive a telephone call at a time when he or she would very much prefer not to answer the call. For example, the person may be in a meeting or may be about to sit down to dinner. Under these circumstances, the person would typically want to answer the phone call only if the call was known to be urgent.
At present, caller identification (ID) systems are available that can provide a recipient with the name or identity of the caller, before an incoming call is answered. Such systems may provide only the caller's phone number, if the caller is unknown. However, the caller's name and phone number may still be insufficient information to enable a called recipient to decide whether or not to answer an inconveniently timed call. Accordingly, it would be useful to provide the call recipient with additional information, such as a brief reference indicating the purpose of the call.
A useful embodiment of the invention is directed to a method for enabling a telephone caller to send a message to a recipient having a specified phone number, wherein the message is defined by a specified group of alphanumeric characters. The method includes the step of receiving a signal comprising first and second signal components, the first signal component representing a message generated by the caller at the caller's phone, and the second signal component representing the specified phone number. The method further includes transmitting the signal to an intermediate site located between the caller and the recipient, and processing the signal at the intermediate site to determine whether or not the recipient is authorized to receive the message represented by the first signal component. The signal is routed to the recipient upon determining that the recipient is so authorized, and the first signal component is decoded at the recipient's location to make the message available to the recipient.
The novel features believed characteristic of the invention are set forth in the appended claims. The invention itself, however, as well as a preferred mode of use, further objectives and advantages thereof, will best be understood by reference to the following detailed description of an illustrative embodiment when read in conjunction with the accompanying drawings, wherein:
The invention provides a method and apparatus whereby a telephone caller can generate a message for transmission to an intended call recipient, as part of the procedure for setting up the call. Thus, the message is sent and made available to the recipient before the call needs to be answered. The message, for example, could comprise a sequence of alphanumeric characters that conveys a message in obvious abbreviated form, or that otherwise indicates the purpose of the call to the recipient. However, the invention is not limited thereto.
Referring to
A message tag sequence is entered or inputted to the telephone network 104 by means of respective buttons of the keypad 116 of caller's telephone 110. A message tag may simply indicate the purpose of the call. Alternatively, the message tag may be a code defining a message that will be readily understood by the intended recipient. Preferably, caller 102 will first sequentially input respective characters of a message tag, and will then enter respective digits of the phone number of the intended recipient.
As an example of use of the embodiment of the invention, a recipient 108 is someone who has placed an item for sale in a classified advertisement. The advertisement includes the recipient's phone number, along with a message tag such as SALE01 for use in calling the recipient in connection with the advertisement. Thus, when a prospective buyer calls the recipient, the caller would first enter the message tag into his phone, and then input the listed phone number. The recipient 108, upon seeing the reference tag SALE01 as recipient's phone is ringing, would know that the call was related to the item the recipient had advertised for sale.
Referring further to
If the recipient is not a subscriber, network 104 will proceed to set up a call between the caller and the intended recipient, but the message will not be routed to the recipient. However, if the intended recipient is found to be a subscriber to the message tag service, then network 104 will direct the call and message to the tag handling device 120. A call will then be set up between the caller and the intended recipient, and the message will be sent to the recipient as part of the call set up procedure, as described hereinafter in further detail.

As is known by those of skill in the art, a signal containing caller ID information is transmitted to a recipient during the ring signal that is sent to the recipient. More particularly, in one conventional arrangement a succession of tones are transmitted to the recipient between the first and second rings, wherein tones or frequencies of 1200 hertz and 2200 hertz represent binary 1's and 0's, respectively. The succession of binary tones comprises ASCII character data that indicates the name and phone number of the caller. This data is decoded at the recipient's phone, to display alphanumeric characters identifying the caller.
It is anticipated that tag handling device 120 could include a component similar to devices of the type described above for generating and transmitting caller ID information to phone call recipients. Such component could uniquely represent every number and letter of the alphabet as a corresponding sequence of binary 1's and 0's, and therefore as a corresponding sequence of binary tones. Other ASCII characters besides letters and numbers could also be represented by binary tone sequences. Character data that encodes a tag message could be transmitted from tag handling device 120 to telephone 114 of caller 108 between successive ring signals, such as between the first and second rings. A decoder 122 located at telephone 114 would then decode the tone sequences, to recover the respectively corresponding characters of the tag message. Thereupon, the characters of the message would be presented to the recipient 108 for viewing, such as by means of a display window 124 incorporated into telephone 114.
As a further feature, tag handling device 120 may be provided with a database for storing a list of tags, or alphanumeric sequences, that are selected by a recipient 108 to define respective corresponding messages. The recipient would enter each tag into the database, after subscribing to the message tag service.
