Incoming call control for wireless sets
First Claim
1. 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 first 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 first 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; and
receiving by the first paging zone controller a second message from the first wireless set via the first base station upon a second base station not being determined whereby the second message defines that the second base station was not determined.

Abstract
A PCS switching system and wireless set that allow the wireless set to control the processing of incoming calls regardless of whether the base station on which the wireless set is registered has capacity to complete a call to the wireless set. When an incoming call is received for a 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 on a base station. If the base station does not have capacity to handle that call, the paging zone controller transmits a page pending message via the base station and a paging channel to the wireless set informing the wireless set that a page is pending and that the wireless set must find a base station with idle capacity. If the wireless set cannot find a base station with idle capacity within the paging zone, the wireless set transmits to the PCS switching system via the paging zone controller a page pending response message that specifies the operations that the PCS system is to perform with respect to the incoming call. The wireless set can specify the call coverage system to which the incoming call is to be routed. In addition, The wireless set can specify a message that will be given to the calling party of the incoming call by the call coverage system. The wireless set can specify that the incoming call is to be placed on hold until the wireless set can find a base station having call capacity to complete the incoming call to the wireless set.

-
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 first 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 first 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; and receiving by the first paging zone controller a second message from the first wireless set via the first base station upon a second base station not being determined whereby the second message defines that the second base station was not determined. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11)

12. A method for receiving incoming telephone calls by a wireless set via base stations, the method comprising the steps of:
-
receiving a first message from a base station on which the wireless set is registered whereby the first message indicates to the wireless set that the wireless set has an incoming telephone call and that the wireless set must find another base station having call capacity to complete the incoming call to the wireless set; sending second message to the base station indicating inability of the wireless set to answer the incoming call upon another base station not being found and indicating in response to actions of the user the type of call coverage system to which the incoming call is to be transferred; and alerting by the wireless set a user upon another base station not being found. - View Dependent Claims (13, 14, 15, 16)

17. An apparatus 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, comprising:
-
means in the wireless switch for receiving an incoming call for a first wireless set of the plurality of wireless sets; means in the wireless switch for communicating the incoming call 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; means in the first paging zone controller for routing the incoming call to the first wireless set via the first base station upon the first base station having call capacity to handle the incoming call; means in the first paging zone controller for transmitting a first message to the first wireless set via the first base station upon the first base station not having call capacity to handle the incoming call whereby the first 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; and means in the first paging zone controller for receiving a second message from the first wireless set via the first base station upon a second base station not being determined whereby the second message defines that the second base station was not determined. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A wireless set for receiving incoming telephone calls via base stations, comprising:
-
means for receiving a first message from a base station on which the wireless set is registered whereby the first message indicates to the wireless set that the wireless set has an incoming telephone call and that the wireless set must find another base station having call capacity to complete the incoming call to the wireless set; means for sending second message to the base station indicating inability of the wireless set to answer the incoming call and indicating in response to actions of the user the type of call coverage system to which the incoming call is to be transferred upon another base station not being found; and means for alerting a user upon another base station not being found. - View Dependent Claims (29, 30, 31, 32)
