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.
