Abstract

A wireless telecommunications system is disclosed that is capable of providing both public wireless service and virtual private network service on existing IS-95 CDMA facilities without changes to the air interface, the hardware design or the protocols for interacting with home location registers. An illustrative embodiment of the present invention comprises: broadcasting from a radio a first SID/NID signal and a FOR_-- NID_-- REG signal to a wireless terminal, wherein the first SID/NID signal is associated with a first set of user zones; receiving from the wireless terminal: (1) a indicium of the wireless terminal'"'"'s identity, and (2) a request to register the wireless terminal based on a second SID/NID signal, wherein the second SID/NID signal is associated with a second set of user zones; transmitting the indicium of the wireless terminal'"'"'s identity to a database; receiving from the database a prioritized list of user zones based on the indicium of the wireless terminal'"'"'s identity; transmitting to the home location register a pseudo directory number that is based on a first user zone, which first user zone is the user zone that has the highest priority in the prioritized list of user zones and that is also a member of the second set of user zones; and receiving from the database a feature set based on the pseudo directory number.

Claims

1. A method comprising the steps of:

broadcasting from a radio a first SID/NID signal and a FOR_-- NID_-- REG signal to a wireless terminal, wherein said first SID/NID signal is associated with a first set of user zones;

receiving from said wireless terminal;

(1) a indicium of said wireless terminal'"'"'s identity; and

(2) a request to register said wireless terminal including a second SID/NID signal which corresponds to one of a predetermined list of systems/networks that said wireless terminal is permitted to access and which optionally differs from said first SID/NID signal;

wherein said second SID/NID signal is associated with a second set of user zones;

transmitting said indicium of said wireless terminal'"'"'s identity to a database;

receiving from said database a prioritized list of user zones based on said indicium of said wireless terminal'"'"'s identity;

transmitting to said database a pseudo directory number that is associated with a first user zone, which first user zone is the user zone that has the highest priority in said prioritized list of user zones and that is also a member of said second set of user zones; and

receiving from said database a feature set associated with said pseudo directory number.

2. The method of claim 1 further comprising the step of registering said wireless terminal based on said feature set.

3. The method of claim 1 further comprising the step of establishing a communication channel with said wireless terminal via said radio.

4. The method of claim 3 further comprising the step of offering a set of features to said wireless terminal based on said first user zone.

5. The method of claim 4 wherein said communications channel is based on CDMA.

6. The method of claim 1 wherein said indicium of said wireless terminal'"'"'s identity is a mobile identification number.

7. The method of claim 1 wherein said database is the home location register of said wireless terminal.

8. A method comprising the steps of:

broadcasting from a first radio a first SID/NID signal and a first FOR_-- NID_-- REG signal to a wireless terminal, wherein said first SID/NID signal is associated with a first set of user zones;

broadcasting from a second radio a second SID/NID signal and a second FOR_-- NID_-- REG signal to said wireless terminal, wherein said second SID/NID signal is associated with a second set of user zones;

receiving at said first radio from said wireless terminal;

(1) a indicium of said wireless terminal'"'"'s identity; and

(2) a request to register said wireless terminal including a third SID/NID signal which corresponds to one of a predetermined list of systems/networks that said wireless terminal is permitted to access and which optionally differs from said first and second SID/NID signals;

transmitting said indicium of said wireless terminal'"'"'s identity to a database;

receiving from said database a prioritized list of user zones based on said indicium of said wireless terminal'"'"'s identity;

transmitting to said database a pseudo directory number that is associated with a first user zone, which first user zone is the user zone that has the highest priority in said prioritized list of user zones and that is also a member of said second set of user zones; and

receiving from said database a feature set associated with said pseudo directory number.

9. The method of claim 8 further comprising the step of registering said wireless terminal based on said feature set.

10. The method of claim 9 further comprising the step of establishing a first communication channel with said wireless terminal.

11. The method of claim 10 further comprising the step of handing-off said wireless terminal to a second communications channel via said second radio and based on a second user zone, which second user zone is a user zone that has the highest priority in said prioritized list of user zones and that is also a member of said second set of user zones.

12. The method of claim 11 wherein said first communications channel and said second communications channel are based on CDMA.

13. The method of claim 11 wherein said first user zone is associated with a first geographic region and said second user zone is associated with a second geographic region.

14. The method of claim 9 wherein said database is the home location register of said wireless terminal.
