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.sub.-- NID.sub.-- 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.
