Abstract

A subscriber conversion system determines at least one code for an existing subscriber of a first wireless communications system to be converted to a second wireless communications system. When the existing subscriber obtains a wireless unit to be used in the second wireless communications system, the conversion system uses the at least one code provided to the existing subscriber to link existing subscriber information from the first wireless communications system to information associated with wireless unit for the second communications system, thereby improving the efficiency of the conversion process. For example, if a service provider wishes to convert from GSM to CDMA, the service provider can provide a secret code and an identification number, such as a directory number (DN), as the codes to the existing GSM subscriber. The subscriber obtains a CDMA wireless unit and commences an activation process to activate the CDMA wireless unit. As part of the activation process, the subscriber provides the secret code and the identification number to the conversion system. The conversion system determines if the secret code and the identification number correspond to the secret code and identification number provided to an existing GSM subscriber. If so, information which is characteristic of the CDMA wireless unit, such as the ESN, DN and/or IMSI, is associated with at least a portion of existing GSM subscriber information, such as billing information and/or features or services. As such, the conversion system uses existing subscriber information to reduce the time required to convert the existing subscriber to the wireless communications system based on the second radio standard.

Claims

1. A method for converting a subscriber of a first wireless communication system to a second wireless communication system, a first wireless device associated with said first wireless communication system and a second wireless device associated with said second wireless communication system, said method comprising:

storing subscriber information relating to a subscription by said subscriber to said first wireless communication system;

assigning a code to said subscriber that associates said subscriber with said subscriber information;

receiving a request from said subscriber to activate said second wireless device;

prompting said subscriber to provide said code; and

activating said second wireless device in said second wireless communication system using at least a portion of said subscriber information.

2. The method of claim 1, wherein prompting said subscriber to provide said code comprises prompting said subscriber to enter said code into said second wireless device.

3. The method of claim 1, wherein storing subscriber information relating to a subscription by said subscriber to said first wireless communication system comprises storing at least one of a mobile identification number, an international mobile subscriber number, a directory number and an electronic serial number.

4. The method of claim 1, wherein activating said second wireless device using at least a portion of said subscriber information comprises programming said second wireless device with at least one of a mobile identification number, an international mobile subscriber number and a directory number.

5. The method of claim 1, wherein storing subscriber information relating to a subscription by said subscriber to said first wireless communication system comprises storing at least billing information for said subscriber of said first wireless communications system.

6. The method of claim 1, wherein storing subscriber information relating to a subscription by said subscriber to said first wireless communication system comprises storing at least call features for said subscriber of said first wireless communications system.

7. The method of claim 1, wherein assigning a code to said subscriber that associates said subscriber with said subscriber information comprises assigning at least one directory number to associate said subscriber with said subscriber information.

8. The method of claim 1, further comprising the step of deactivating said first wireless device upon the activation of said second wireless device.

9. The method of claim 1, further comprising:

assigning said first wireless device a directory number; and

assigning said second wireless device the same said directory number upon activation of said second wireless device in said second wireless communication system.

10. The method of claim 1, further comprising:

assigning a first directory number to said first wireless device;

assigning a second directory number to said second wireless device; and

forwarding calls made to said first directory number to said second wireless device.

11. The method of claim 1, wherein said first wireless communication system uses a first radio standard and said second wireless communication system uses a second radio standard.

12. A method for converting a subscriber of a first wireless communication system to a second wireless communication system, said method comprising:

creating a first subscriber profile on a subscriber database, said subscriber profile including information relating to a subscription by said subscriber to said first wireless communication system;

assigning a subscriber code to said subscriber;

receiving a request from said subscriber to activate a wireless unit on said second wireless communication system, said wireless unit storing device information characteristic of said wireless unit;

prompting said subscriber to enter said subscriber code into said wireless unit;

receiving said subscriber code and said device information from said wireless unit; and

generating a second subscriber profile based on said first subscriber profile and said device information, said second subscriber profile relating to a subscription by said subscriber to said second wireless communication system.

13. The method of claim 12, wherein said first subscriber profile comprises at least one of a mobile identification number, an international mobile subscriber number, a directory number and an electronic serial number.

14. The method of claim 12, wherein said first subscriber profile comprises at least one of billing information and subscription features for said subscription to said first wireless communication system.

15. The method of claim 12, wherein assigning a subscriber code to said subscriber comprises assigning a directory number to said subscriber.

16. The method of claim 12, wherein receiving said subscriber code and said device information from said wireless unit comprises receiving said subscriber code and at least one of a electronic serial number, a mobile identification number and an international mobile subscriber number from said wireless unit.

17. The method of claim 12, wherein prompting said subscriber to enter said subscriber code comprises the steps of:

providing said subscriber with a customer service number;

receiving a call on said customer service number from said subscriber; and

initiating an automated activation process such that a machine-generated voice instructs said subscriber to enter said subscriber code.

18. The method of claim 12, further comprising sending at least a portion of the second subscriber profile to at least one of a home location register, an authentication center and a central database or databases distributed throughout the second wireless communication system.

19. The method of claim 12, further comprising programming said wireless unit with at least a portion of said second subscriber profile.

20. The method of claim 19, wherein programming said wireless unit with at least a portion of said second subscriber profile comprises programming said wireless unit using over the air programming protocols.
