Abstract

An exemplary extended dialing plan allows use of one or more special characters, such as the # digit and the * digit, as dialable digits. The telecommunications network receives a string of characters representing a destination address from a first communication device, for use in routing a communication through the network to a second communication device. The received string of characters includes a number digit in the first position in the string and at least one non-numerical special character in another position. The character string is received from the first communication device by the network, the character string is analyzed and used to route the communication through the telecommunication network to the destination address based at least in part on the character string with at least one non-numerical special character.

Claims

1. A method, comprising steps of:

receiving at an element of a telecommunication network from a first communication device a telephone call, wherein the telephone call includes a destination telephone address assigned to a second communication device and used for routing the telephone call from the first communication device through the network to the second communication device, and wherein the destination telephone address is represented by a string of characters including number digits and at least one non-numerical special character, one of the number digits being in the leading position in the string, and each non-numerical special character being at a position in the string other than the leading position;

analyzing the string including the at least one non-numerical special character including validating the string using a look-up-table containing numerical characters and the at least one non-numerical character; and

responsive to the analysis, routing the telephone call through the network, based at least in part on the at least one non-numerical special character included in the string.

2. The method of claim 1, wherein the string is formatted as a ten digit telephone number.

3. The method of claim 2, wherein each non-numerical special character is one of a # character and a * character.

4. The method of claim 1, wherein the network is a wireless mobile communication network, and at least the first communication device is a wireless communication device.

5. The method of claim 1, wherein analyzing the string comprises identifying the one number digit in the lead position and identifying the number digit or non-numerical character located at each subsequent position within the string individually, based on sequential position within the string.

6. The method of claim 1, wherein analyzing the string comprises:

comparing the string to a data set to determine if the address identified by the string exists; and

upon determining that the address associated with the string exists, informing another element of the network that the communication should be routed.

7. The method of claim 1, wherein routing the communication comprises sending the communication from the first device through the network to the second device using the string of characters as the destination address.

8. The method of claim 7, wherein routing the communication comprises:

identifying a geographic location of the second communication device associated with the destination address based at least in part upon a sequence of characters contained in a portion of the string; and

routing the telephone call through the network based on the identified geographic location.

9. The element of the network configured to implement the method of claim 1.

10. A telecommunication network comprising a plurality of elements for routing communications through the network, wherein at least one of the elements of the network is configured to be capable of implementing functions including functions to:

receive from a first device a telephone call, wherein the telephone call includes a destination telephone address assigned to the second device and used for routing the telephone call through the telecommunication network from the first device to the second device, and wherein the destination telephone address is represented by a string of characters including number digits and at least one non-numerical special character;

analyze the string including the at least one non-numerical special character including validating the string using a look-up-table containing numerical characters and the at least one non-numerical character; and

responsive to the analysis, route the communication through the telecommunication network, based at least in part on the at least one non-numerical special character included in the string.

11. The telecommunication network of claim 10, wherein the string is formatted as a ten digit telephone number, the digit in the leading position in the string being a number digit.

12. The telecommunication network of claim 10, wherein the non-numerical special character is one of a # character and a * character.

13. The telecommunications network of claim 10, wherein the network is a wireless mobile communication network, and the first device is a wireless communication device.

14. The telecommunications network of claim 10, wherein the function to route the communication includes functions to:

identify a geographic location of the second device associated with the destination address based at least in part upon a sequence of digits contained in a portion of the string; and

route the telephone call through the network based on the identified geographic location.

15. An article of manufacture, comprising:

a non-transitory, machine readable storage medium; and

information embodied in the medium for configuring an element of a telecommunications network to be capable of performing functions, wherein the functions include functions to;

receive from a first device a telephone call, wherein the telephone call includes a destination telephone address assigned to a second device and used for routing the telephone call through a telecommunication network from the first device to the second device, and wherein the destination telephone address is represented by a string of characters including number digits and at least one non-numerical special character;

analyze the string including the at least one non-numerical special character including validating the string using a look-up-table containing numerical characters and the at least one non-numerical character; and

responsive to the analysis, route the telephone call through the telecommunication network, based at least in part on the at least one non-numerical special character included in the string.

16. The article of manufacture of claim 15, wherein the string is formatted as a ten digit telephone number, the digit in the leading position in the character string being a number digit.

17. The article of manufacture of claim 16, wherein the non-numerical special character is one of a # character and a * character.

18. The article of manufacture of claim 15, wherein the function to analyze the string comprises the function to identify the number digit or non-numerical character located at each position within the number string individually based on sequential position within the string.

19. The article of manufacture of claim 15, wherein the function to analyze the string further comprises the function to:

compare the string to a data set to determine if the address identified by the string exists; and

upon determination that the address associated with the string exists, inform the network that the communication should be routed.

20. The article of manufacture of claim 15, wherein the function to route the communication includes functions to:

identify a geographic location of the second device associated with the destination address based at least in part upon a sequence of digits contained in a portion of the character string; and

route the telephone call through the network based on the identified geographic location.
