Abstract
Abstract A PCS switching system where a wireless set registers on a base station regardless of whether the base station has capacity to complete a call for the wireless set. When an incoming call is received for the wireless set, a central computer providing overall control of the PCS system directs this call to a paging zone controller of a paging zone in which the wireless set is registered. If the base station does not have capacity to handle that call, the paging zone controller transmits a message via the base station and a paging channel to the wireless set informing the wireless set that a page is pending and that it must find a base station with idle capacity. The wireless set does this by listening to the paging channel until a base station is determined that has idle capacity. The base stations periodically transmit on the paging channel, and each of their messages includes the present capacity of the base station. The wireless set establishes communication with the new base station and ceases to be in communication with the original base station. Since the wireless set is already registered with the paging zone controller, it is not necessary for the paging zone controller to re-register the wireless set with the wireless switching network when the wireless set moves from one base station to another base station within the same paging zone.

Total Claims: 14
Claim 1
Independent Claim
285 words
A method for paging a plurality of wireless sets each registered on one of a plurality of base stations which are divided into sets with each set being interconnected to an individual one of a plurality of paging zone controllers with each of the paging zone controllers controlling one of a plurality of paging zones and each of the paging zone controllers being interconnected to a wireless switch, the method comprising the steps of: receiving an incoming call for a first wireless set of the plurality of wireless sets by the wireless switch; communicating the incoming call by the wireless switch to a first paging zone controller of the plurality of paging zone controllers controlling a first paging zone of the plurality of paging zones upon the first wireless set being registered on a first base station of a first set of base stations that are interconnected to the first paging zone controller; routing the incoming call by the first paging zone controller to the first wireless set via the first base station upon the first base station having call capacity to handle the incoming call; transmitting a message to the first wireless set by the first paging zone controller via the first base station upon the first base station not having call capacity to handle the incoming call whereby the message instructs the first wireless set to find and register on a second base station of the first set of base stations that has capacity to handle the incoming call; determining and re-registering on the second base station by the first wireless set; and routing the incoming call by the first paging zone controller to the first wireless set via the second base station.
Claim 2
Independent Claim

Claim 4
Dependent Claim
74 words
The method of claim 1 further comprises the step of processing a registration of the first wireless set on the first base station with the wireless switch by the first paging zone controller upon that registration being the first registration of the first wireless set in the first paging zone; and the step of re-registering on the second base station comprises the step of processing that registration only within the first paging zone controller.
Claim 5
Dependent Claim
109 words
The method of claim 3 further comprises the steps of registering by the first wireless set on a third base station of a second set of base stations controlled by a second paging zone controller of the plurality of paging zone controllers in a second paging zone of the plurality of paging zones; processing the registration by the second paging zone controller with the wireless switch; informing the first paging zone controller by the wireless switch that the first wireless set is now registered in the second paging zone; and eliminating reference to first wireless set as being registered in the paging zone by the first paging zone controller.
Claim 6
Dependent Claim
117 words
The method of claim 3 further comprises the steps of registering by the first wireless set on a third base station of a second set of base stations controlled by a second paging zone controller of the plurality of paging zone controllers in a second paging zone of the plurality of paging zones whereby the registration is initiated by the first wireless set transmitting a registration message indicating a paging zone switch to the third base station; and processing the registration by the second paging zone controller with the wireless switch whereby the wireless switch does not inform the first paging zone controller that the first wireless set is no longer registered in the first paging zone.
Claim 7
Dependent Claim
