Abstract

A wireless telecommunications system is capable of providing both public wireless service and private network service on existing IS-95 CDMA facilities without changes to the air interface or the hardware design. An illustrative embodiment of the present invention comprises: broadcasting an SID/NID signal to a wireless terminal, wherein the SID/NID signal is associated with a set of user zones; receiving from the wireless terminal: (1) an indicium of the wireless terminal'"'"'s identity, and (2) a request to establish a communications channel based on the SID/NID signal; transmitting the indicium of the wireless terminal'"'"'s identity to a home location register; receiving from the home location register a prioritized list of user zones based on the indicium of the wireless terminal'"'"'s identity; and establishing the communications channel 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 set of user zones.

Claims

1. A method comprising the steps of:

broadcasting a combination System Identification and Network Identification signal (_-- SID/NID signal_--) to a wireless terminal, wherein said SID/NID signal is associated with a set of user zones;

receiving from said wireless terminal;

(1) an indicium of said wireless terminal'"'"'s identity, and (2) a request to register said wireless terminal based on said SID/NID signal;

transmitting said indicium of said wireless terminal'"'"'s identity to a home location register;

receiving from said home location register a prioritized list of user zones based on said indicium of said wireless terminal'"'"'s identity; and

registering said wireless terminal based on 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 set of user zones.

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

3. The method of claim 2 further comprising the step of offering a set of features to said wireless terminal based on said chosen user zone.

4. The method of claim 3 wherein said communication channel is based on CDMA.

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

6. A method comprising the steps of:

broadcasting a first combination System Identification and Network Identification signal (_-- (SID/NID signal_--) to a wireless terminal, wherein said first SID/NID signal is associated with a first set of user zones;

broadcasting a second SID/NID signal to said wireless terminal, wherein said second SID/NID signal is associated with a second set of user zones;

receiving from said wireless terminal;

(1) a indicium of said wireless terminal'"'"'s identity, and (2) a request to said register said wireless terminal based on said first SID/NID signal;

transmitting said indicium of said wireless terminal'"'"'s identity to a home location register;

receiving from said home location register a prioritized list of user zones based on said indicium of said wireless terminal'"'"'s identity; and

registering said wireless terminal based on a first user zone, which first 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 first set of user zones.

7. The method of claim 6 further comprising the step of establishing a communications channel with said wireless terminal.

8. The method of claim 7 wherein said communications channel is based on CDMA.

9. The method of claim 6 wherein said first user zone is associated with a first geographic region and said second user zone is associated with a second geographic region.
