Abstract

By establishing double star short dialing codes (short codes) a party may have assigned to it a two, three, four or five digit name or number that is easy to remember because it has only a few numbers. When that number is dialed, the number is directed to a special translator that translates the short code to the full number, or to a series of called numbers, for subsequent routing through the telephone network. Because of the shortage on the numbering plan, the short code is indicated to the telephone network by the calling user dialing a unique prefix combination of non-numeric digits. In one embodiment, a control digit within the short code indicates to the system also the length of the short code. In this manner, variable length short numbers can be utilized for telephone or SMS messaging routing purposes, thus expanding the existing dial plan for the short number purposes.

Claims

1. A public switched telephone network routing system comprising:

at least one detection circuitry for determining telephone network calling connections to a called party initiated using as a prefix and discriminating sequence, a unique combination of non-number dialed digits;

circuitry responsive to receipt of dialed digits pertaining to a detected calling connection having said unique combination of non-number dialed digits for accepting an expected number of dialed digits pertaining to said calling connection, said expected number of dialed digits being less than a full compliment of dialed digits required to complete a calling connection to said called party; and

circuitry for enabling said full compliment of digits to be supplied to said telephone network so that said calling connection can be completed through said telephone network to said called party.

2. The routing system of claim 1 wherein said enabling circuitry comprises at least one database.

3. The routing system of claim 2 further comprising:

means based at least in part on an identity of digits received as part of said received dialed digits for determining said expected number of dialed digits.

4. The routing system of claim 3 wherein said non-number dialed digits are selected from a list of:

star, pound.

5. The routing system of claim 1 further comprising:

circuitry for routing received dialed digits to a location remote from said telephone network switching point upon detection of calling connections to a called party initiated using a unique combination of non-number dialed digits;

wherein said enabling circuitry comprises at least one database located at said remote location and wherein said non-number dialed digits are selected from a list of;

star, pound.

6. The routing system of claim 5 wherein:

circuitry based at least in part on an identity digits received as part of said received dialed digits for determining said expected number of dialed digits; and

circuitry for routing received dialed digits to different locations remote from said telephone network switching point based upon a determined expected number of dialed digits; and

wherein said enabling circuitry comprises at least one database located at a remote location to which said dialed digit have been routed.

7. A method of competing calls in a telephone system in which calls are routed from a calling station to a called station under control of digits dialed from said calling station, said digits representative of a pre-established numeric telephone number having a fixed number N of numeric digits, said method comprising:

detecting a calling station short code dialed called number containing a specific combination of non-numeric dialed digits as well as numeric digits representative of a called station, said detected numeric digits being less than N; and

sending said detected short code number to at least one short code translation table separate from a translation table used for INWATS translation such that a telephone connection can be established from said calling station to said called station under control of said detected short code dialed number.

8. The method of claim 7 wherein said non-numeric dialed digits are selected from the list of:

star, pound.

9. The method of claim 8 wherein a length of said calling station short code is L digits, said method further comprising:

determining L based on a value of a first digit following said specific combination of non-numeric dialed digits.

10. The method of claim 8 wherein a length of said calling station short code is L digits, said method further comprising:

determining L based on a position of a non-numeric dialed digit in said short code dialed called number.

11. The method of claim 8 wherein a length of said calling station short code is L digits, said method further comprising:

selecting said translation table based on a determined value of L.

12. The method of claim 11 further comprising:

determining L based on a value of a first digit following said specific combination of non-numeric dialed digits.

13. The method of claim 11 further comprising:

determining L based on a value of at least one digit in said short code.

14. A method for using short code dialing in a telephone network, said method comprising:

routing calls from a calling station to a called station or to a series of called numbers under control of a fixed length calling number pre-assigned to said called station, said fixed length being N numeric digits; and

routing calls from a calling station to a called station under control of a short code number dialed from said calling station, said short-code identified by a pre-assigned combination on non-numeric digits in said dialed number.

15. The method of claim 14 wherein said short code routing comprises:

translating between a received short code and a corresponding fixed length pre-assigned number of said called station.

16. The method of claim 15 wherein said short code number is of variable length V.

17. The method of claim 16 wherein length V is determined based upon values of certain digits within said short code.

18. The method of claim 17 wherein said short code routing comprises:

sending received short codes to a particular database to obtain translation to said corresponding fixed length station number, said particular database depending upon said determined length V.

19. The method of claim 18 wherein at least some of said particular databases are located at separate physical locations from each other.

20. A method for using short code dialing in a telephone network, said method comprising:

routing calls from a calling station to a called station or to a series of called stations under control of a fixed length calling number pre-assigned to said called station, said fixed length being N numeric digits; and

routing calls from a calling station to a called station under control of a short code number dialed from said calling station, said short-code identified by a pre-assigned combination on non-numeric digits in said dialed number, said short code routing comprising;

translating between a received short code and a corresponding fixed length pre-assigned number of said called station under control of a database maintained independent of said telephone network by a short code provider.

21. The method of claim 20 wherein said short code number is of variable length V wherein length V is determined based upon values of certain digits within said short code.

22. The method of claim 21 wherein said short code provider is determined by a determination of said variable length V.
