Abstract
Abstract A wireless telecommunications system that is capable of providing multiple virtual wireless networks (e.g., a public network and/or one or more private networks) from a single IS-95 compliant CDMA radio without changing the air interface or modifying existing hardware designs. Includes the steps of 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; and registering the wireless terminal 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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
182 words
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; wherein SID/NID is the combination of the system identification signal and network identification signal and FOR -- NID -- REG is the foreign network registration signal; receiving from said wireless terminal: (1) a indicium of said wireless terminal's identity and (2) a request to register said wireless terminal based on a second 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; 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 second set of user zones.
Claim 2
Independent Claim
182 words
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; wherein SID/NID is the combination of the system identification signal and network identification signal and FOR -- NID -- REG is the foreign network registration signal; receiving from said wireless terminal: (1) a indicium of said wireless terminal's identity and (2) a request to register said wireless terminal based on a second 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; 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 second set of user zones.
Claim 3
Dependent Claim
21 words
The method of claim 1 further comprising the step of establishing a communication channel with said wireless terminal via said radio.
Claim 4
Dependent Claim
25 words
The method of claim 2 further comprising the step of offering a set of features to said wireless terminal based on said first user zone.
Claim 5
Dependent Claim
13 words
The method of claim 3 wherein said communications channel is based on CDMA.
Claim 6
Dependent Claim
18 words
The method of claim 1 wherein said indicium of said wireless terminal's identity is a mobile identification number.
Claim 7
Dependent Claim
17 words
The method of claim 1 wherein said database is the home location register of said wireless terminal.
Claim 8
Independent Claim
207 words
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; wherein SID/NID is the combination of the system identification signal and network identification signal and FOR -- NID -- REG is the foreign network registration signal; 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 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 a third SID/NID signal; 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; 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.
Claim 9
Independent Claim
207 words
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; wherein SID/NID is the combination of the system identification signal and network identification signal and FOR -- NID -- REG is the foreign network registration signal; 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 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 a third SID/NID signal; 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; 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.
