This invention relates to telecommunication systems and methods. In particular, the invention relates to telecommunication systems and methods that rely on improved area codes.
The present telecommunication systems rely on telephone area codes that are three-digit numbers which are assigned in a haphazard manner with no organization of any kind. Moreover, the present area codes do not reveal anything about the area being called. California, for example, has been assigned area codes ranging from a very low 209 to a very high 954.
The ongoing background art is characterized by U.S. Pat. Nos. 3,634,631; 3,870,821; 5,018,191; 5,467,390 and 7,039,174; the disclosures of which patents are incorporated by reference as if fully set forth herein.
The purpose of a preferred embodiment of the invention is to provide an improved telecommunication system that relies on area codes that have meaning. One advantage of a preferred embodiment of the invention is that area codes would be more memorable.
In a preferred embodiment, the invention is a system and method for receiving telephone user input and routing telephone calls. In a telecommunication system that is capable of routing telephone calls to a communications device of a particular subscriber within an area code, another preferred embodiment of the invention is a system for routing a telephone call from a caller to said specific communications device, said system comprising: means for assigning a first telephone number to the particular subscriber; and means for routing the telephone call to the specific communications device of the particular subscriber said means for routing being programmed to recognize an area code; wherein said area code is a sequence of characters established in accordance with one of the schemes disclosed herein.

Referring to
In a preferred embodiment of the invention, telecommunication system 2 relies on an improved area code scheme. In one embodiment, telecommunication system 2 relies on area codes that indicate which State is encompassed by each area code.
In a preferred embodiment, each two-character area code is equivalent to the two-character U.S. postal state or possession or military “state” abbreviation (postal code). The area codes may be stored in a memory of telecommunication system 2 in alphabetical order, as follows, by state name or possession name or by military “state” name, for example:
Letter keys are already available on new cellular telephones which feature a computer keyboard. In these telephones, a standard integrated-circuit chip converts 127 input keys, including upper case letters, lower case letters, numbers, punctuation, etc. into seven-bit binary symbols, in accordance with the standard ASCII digital coding scheme. An eight-bit expanded list is also available.
The number of area codes required to serve each telecommunication system 2 varies with the population of each state and the telephone number capacity of each area code. Present art area codes each service 7.92 million subscribers who share a mixture of landline, facsimile and cellular numbers. This approach requires hundreds of area codes to serve a country the size of the United States. With the low capacity of each background art area code, a telecommunication system that relied on two-character area codes would not have a sufficient number of area codes.
In a preferred embodiment, the telecommunication system of U.S. Pat. No. 7,039,174 is used with an embodiment of the invention disclosed herein. Use of this telecommunication system allows a doubling of area code capacity and relies on eight-digit cellular numbers created by adding a * prefix to a conventional seven-digit telephone number. Each area code would then include another set of 7.92 million numbers containing the *prefix which would be reserved for use by cellular phones only. In this embodiment, two-character area codes have enough capacity to provide full service.
In another preferred embodiment, the invention calls for reducing telephone area codes from three digits to two digits. This embodiment allows the use of an eight-digit cellular phone number without changing the total number of digits presently in use (ten digits=three-digit area code plus conventional seven-digit telephone). With this embodiment, changes to the telecommunication system software are required, but no changes are required to present art telephone instrumentation or handsets.
In yet another preferred embodiment, where letters are fully available, telecommunication system 2 relies on two-character area codes that are equivalent to the two-character postal state abbreviations, such as: AL, AK, AZ, AR, CA, C1, CO, etc. The C1 area code is an extra area code for California, which could also have, in an alternative embodiment, CN for northern California and CS for southern California. The 2-digit area code plus an 8-digit cellular number would preserve the long distance telephone number at its present 10 digits.
If seven letters were used instead of seven digits for a telephone number, the capacity of each area code would increase from the present 10 million (107) to eight billion (267) accounts. With this capacity, only one two-character area code is needed per state. (The present system has two million unavailable numbers starting with 0 or 1 and 80,000 reserved numbers for an actual total of 7.92 million).
Many variations of the invention will occur to those skilled in the art. Some variations include use of area codes that are equivalent to two-character abbreviations. Other variations include use of area codes that are two-character postal state name abbreviations. All such variations are intended to be within the scope and spirit of the invention.
Although some embodiments are shown to include certain features, the applicant specifically contemplates that any feature disclosed herein may be used together or in combination with any other feature on any embodiment of the invention. It is also contemplated that any feature may be specifically excluded from any embodiment of the invention.
This application claims the benefit of U.S. Provisional Patent Application No. 60/965,379, filed Aug. 17, 2007, the disclosure of which patent application is incorporated by reference as if fully set forth herein.
