Shared service system for wireless terminals

Limiting the base stations (102-116) to which a wireless terminal (e.g. 124) will attempt to establish communication may be done by a wireless switching system (101) or another system having the capability of storing within each individual wireless terminal a list of base stations (e.g. 112,113,102,103) that can be utilized by that wireless terminal. When a wireless terminal first registers on the wireless switching system (101), the wireless switching system would be responsive to the identification code of the wireless terminal to transmit a list of base stations that can be utilized by the wireless terminal to the wireless terminal. The wireless terminal then stores that list for future use. In another embodiment, each tenant would be assigned a group number. Each of the base stations would periodically transmit the numbers of the groups that could access the base station. A wireless terminal monitors these group numbers before attempting to register on a base station.
