Method and apparatus for routing a call to a mobile communication unit in a telepoint communication system
First Claim
1. An apparatus coupled to a public switched telephone network (PSTN) to facilitate routing of an inbound call on the PSTN to a mobile communication unit in a telepoint communication system, wherein the apparatus communicates with the PSTN to route the inbound call within the PSTN, the apparatus comprising:
- at least one telepoint base station (TBS) coupled to the PSTN for receiving registration information from the mobile communication unit, and for transmitting the registration information received from the mobile communication unit; and
a controller coupled to the PSTN and the at least one TBS for receiving the registration information from the at least one TBS and storing the registration information therein, andwherein when the controller receives call information from the PSTN in response to the PSTN receiving an inbound call for the mobile communication unit, the controller utilizes the registration information and the call information to communicate the receipt of the inbound call to the at least one TBS, whereby, in response to the communication from the controller, the at least one TBS reserves a communication channel to receive the inbound call and communicates routing information regarding the reserved communication channel to the PSTN to the controller, in response to communication of the receipt of the inbound call therefrom, andwherein the controller further provides the routing information received from the at least one TBS to the PSTN, the PSTN routes the inbound call over the reserved communication channel and thence via the at least one TBS to the mobile communication unit.

Abstract
A telepoint communication system 100 where the affiliation of communication unit 125 and 130 with telepoint base station 120 and 122 is maintained at a mobility management unit (MMU) 117. When an inbound call for the mobile communication unit 125 and 130 is received on the PSTN 110, the location of the mobile communication unit 125 and 130 is determined from the MMU 117 and a communication channel at the telepoint base station is reserved, and routing information to the reserved communication channel is provided to the PSTN, enabling the mobile communication unit 125 and 130 to receive the inbound call.

8. A method for routing an inbound call to a mobile communication unit, wherein the inbound call is received on a public switched telephone network (PSTN), and wherein the PSTN is coupled to at least one location via a communication channel of the PSTN, and wherein the communication channel has an identification number associated therewith, and wherein the mobile communication unit is within communicable range of the at least one location, wherein the method comprises the steps of:
-
a) transmitting a reservation request to the at least one location to reserve the communication channel; b) in response to the request in step (a), receiving the identification number of the reserved communication channel from the at least one location; and c) transmitting the identification number of the reserved communication channel to the PSTN, thereby enabling the PSTN to route the inbound call to the reserved communication channel using the identification number thereof, and thence to the at least one location, allowing the mobile communication unit to receive the inbound call via the at least one location. - View Dependent Claims (9, 10, 11)

12. A method for routing a call from a public switched telephone network (PSTN) to a mobile communication unit in a telepoint communication system, wherein the telepoint communication system comprises at least one telepoint base station (TBS) operably coupled to the PSTN via at least one communication channel having an identification number affiliated with the at least one TBS, wherein the method comprises the steps of:
-
a) receiving registration information from a mobile communication unit by the at least one TBS; b) in response to receiving the registration information by the at least one TBS, transmitting the registration information to a controller, wherein the controller is coupled to the PSTN; c) in response to receiving the registration information by the controller, storing the registration information therein; d) receiving an inbound call notification at the controller from the PSTN in response to the PSTN receiving an inbound call for the mobile communication unit; e) utilizing the registration information and the inbound call notification to transmit an inbound call message to the at least one TBS from the controller; f) in response to receiving the inbound call message by the at least one TBS, reserving the at least one communication channel of the PSTN to receive the inbound call; and g) transmitting the identification number of the reserved at least one communication channel from the PSTN to the controller, wherein the controller further transmits the the identification number of the reserved at least one communication channel of the PSTN to the PSTN in response to receiving the identification number of the reserved at least one communication channel of the PSTN from the at least one TBS, wherein the identification number of the at least one communication channel Of the PSTN enables the PSTN to route the inbound call to the reserved at least one communication channel of the PSTN and thence via the at least one TBS to the mobile communication unit. - View Dependent Claims (13, 14)

15. A method of routing a call from a public switched telephone network (PSTN) to a base station of a wireless communication network, the method comprising the steps of:
-
receiving, at the PSTN, an inbound call for a mobile communication unit; sending an inbound call notification containing, which identifies the mobile communication unit, from the PSTN to a controller of the wireless communication system; determining, within the controller, the base station with which the mobile communication unit is currently associated; sending a notification of the inbound call from the controller to the base station with which the mobile communication unit is associated; reserving, at the base station, a communication channel between the base station and the PSTN over which the inbound call is to be routed; notifying the controller, by way of a message from the base station, as to the communication channel reserved; notifying the PSTN, by way of a message from the controller, as to the communication channel reserved; and routing the inbound call from the PSTN to the base station over the communication channel reserved.
