Abstract

At least two different methods and various combinations of apparatus are disclosed for remotely actuating call forwarding when the subscriber of a wireless network does not have their mobile device with them or have access to the internet. In one method the subscriber dials a string of digits comprising a wireless carrier routing string to route the call to within their wireless network. A service feature invoking string of a single digit or two dialed digits is entered to identify a sub-address appendix. More importantly, the subscriber identifies themselves to their wireless network by entering a sequence of dialed digits, preferably their subscriber number (SN) and a personal identifier or PIN where the feature invoking string separates the SN from the PIN entry. Finally, the subscriber, if calling from the destination phone enters a digit signifying they have reached the destination. If the subscriber is calling from an intermediate phone along the way to their destination, the subscriber enters the entire destination telephone number. An alternative embodiment involves the use of interactive voice response equipment within the wireless network accessed by the caller inside or outside the wireless network. The call forwarding service feature or other features such as entering a service feature cancellation command, a follow me list of telephone numbers and scheduled times or a list of priorities for receiving calls (such as a friends and family list versus junk mail) may be actuated from an intermediate phone or a destination phone inside or outside the network.

Claims

1. A method of actuating call forwarding remotely in a wireless network from a telecommunications device inside or outside the wireless network comprising:

receiving a dialed string of digits comprising a sequence of dialed digit sequences having a first dialed digit sequence for routing a call from the telecommunications device to within the wireless network;

routing the call to wireless network apparatus for providing an identified service;

interpreting data representing a second sequence of dialed digits of the dialed string of digits for verifying caller identity within the wireless network;

interpreting data representing a third sequence of digits of the dialed string of digits as indicative of a telephone number of a telecommunications device inside or outside the wireless network to which calls to a wireless device of a verified caller are to be forwarded.

2. A method as recited in claim 1 further comprising the step of translating the second and third sequence of digits of the dialed string of digits into compressed data for transmission over a link to a network platform of the wireless network apparatus.

3. A method as recited in claim 1 wherein the second sequence of dialed digits comprises a subscriber number and a personal identifier code.

4. A method as recited in claim 3 further comprising the step of indicating the end of data entry of a personal identifier code by a special dialed digit following the second sequence of dialed digits.

5. A method as recited in claim 1 further comprising the step of indicating that a subscriber is calling from a destination telephone by receiving a special dialed digit to represent the third sequence of digits of the dialed string of digits.

6. A method as recited in claim 5 further comprising the step of recording the destination telephone number from caller identification number data in a location register of the wireless network responsive to receipt of the special dialed digit.

7. A method as recited in claim 1 further comprising the step of recording the destination telephone number from the third sequence of digits of the dialed string of digits in a location register of the wireless network.

8. A method as recited in claim 1 further comprising the steps of interpreting a received sequence of one or two dialed digits of the dialed string of digits as a service feature selecting sequence of digits within the wireless network.

9. A method as recited in claim 8 wherein the received sequence of digits comprises a single digit for selecting one feature and represents a GSM octet for identifying a sub-address appendix following routing data.

10. A method of actuating call forwarding remotely from a telecommunications device inside or outside a wireless network comprising:

receiving a dialed string of digits comprising a sequence of dialed digit sequences having a first dialed digit sequence for routing a call from the telecommunications device to within the wireless network;

connecting the call to network apparatus in the wireless network including interactive voice response equipment, the interactive voice response equipment for requesting verbal responses or dialed digit sequences;

interpreting a service feature invoking request at the network apparatus;

interpreting input data or an intelligible response for verifying caller identity at the network apparatus;

interpreting input data or an intelligible response as indicative of a telephone number of a telecommunications device inside or outside the wireless network to which calls to a wireless device of a verified caller are to be forwarded.

11. A method as recited in claim 10 further comprising the step of translating caller identity data into compressed data for transmission over a link to a selected network platform having interactive voice response.

12. A method as recited in claim 10 further comprising the step of indicating an end of data entry by a special dialed digit following the entry of caller identity data.

13. A method as recited in claim 10 further comprising the step of indicating that a subscriber is calling from a destination telephone by receiving a special dialed digit to represent the telecommunications device to which calls are to be forwarded.

14. A method as recited in claim 13 further comprising the step of recording the destination telephone number from caller identification number data in a location register of the wireless network.

15. A method as recited in claim 10 further comprising the step of recording the voiced or dialed destination telephone number in a location register of the wireless network.

16. A network platform of a wireless network to which an incoming call has been routed by a mobile switching center within the wireless network, the network platform being connected to the incoming call according to a first dialed digit sequence of a dialed string of digits comprising a plurality of dialed digit sequences, the network platform comprising:

a controller having access to a location register, the controller interpreting a second sequence of digits of the dialed string of digits for verifying caller identity at the network platform, and interpreting a third sequence of digits of the dialed string of digits as indicative of a telephone number of a telecommunications device inside or outside the wireless network to which calls to a wireless device of a verified caller are to be forwarded; and

the location register, responsive to a control signal from the network platform, indicating routing information for the incoming call to be routed according to the third sequence of digits.

17. A network platform as recited in claim 16 wherein network apparatus interprets a sequence of digits comprising one or two dialed digits representing a GSM octet for identifying a sub-address appendix, the dialed digits used for forwarding incoming call data to a selected network platform.

18. A network platform as recited in claim 16 wherein the third sequence of digits comprises a single digit indicative that the location register is to record caller identification number data as the call forward destination number.

19. A network platform of a wireless network to which an incoming call has been routed from inside or outside the wireless network by a mobile switching center within the wireless network, the network platform being connected to the incoming call according to a first dialed digit sequence of a dialed string of digits comprising a plurality of dialed digit sequences, comprising:
