Full duplex individual call via linked single frequency repeaters
First Claim
1. A method for enabling full duplex individual calls in repeater mode between two subscriber units in a N:
- 1 slotting ratio time division multiple access (TDMA) radio system, the method comprising;
receiving, at a first repeater, a request for a full duplex individual call from a first subscriber unit identifying a second subscriber unit as a target of the full duplex individual call;
determining, by a radio controller associated with the first repeater, whether to grant or deny the request; and
responsive to determining to grant the request;
assigning, by the radio controller, a first time slot of the N time slots on a first single frequency for one of inbound and outbound transmissions for the full duplex individual call between an assigned second repeater and the first subscriber unit and a second time slot of the N time slots on the first single frequency for the other of inbound and outbound transmissions for the full duplex individual call between the assigned second repeater and the first subscriber unit; and
causing, by the radio controller, a grant message to be transmitted to the first subscriber unit indicating the assigned first single frequency and assigned first and second time slots.

Abstract
A method for enabling full duplex individual calls in repeater mode between two subscriber units (SUs) in a N:1 slotting ratio time division multiple access (TDMA) radio system includes receiving a request for a full duplex individual call from a first SU identifying a second SU as a target of the call. Determining to grant the request and subsequently assigning a first time slot of the N time slots on a first single frequency for one of inbound and outbound transmissions for the call between an assigned second repeater and the first SU and a second time slot on the first single frequency for the other of inbound and outbound transmissions for the call between the assigned second repeater and the first SU. Further, a grant message is transmitted to the first SU indicating the assigned first single frequency and assigned first and second time slots.

17. A radio controller device for enabling full duplex individual calls in repeater mode between two subscriber units in a N:
- 1 slotting ratio time division multiple access (TDMA) radio system, the device comprising;
a transceiver; a memory; and a processor configured to; receive, via a first repeater and the transceiver, a request for a full duplex individual call from a first subscriber unit identifying a second subscriber unit as a target of the full duplex individual call; determine whether to grant or deny the request; and responsive to determining to grant the request; assign a first time slot of the N time slots on a first single frequency for one of inbound and outbound transmissions for the full duplex individual call between an assigned second repeater and the first subscriber unit and a second time slot of the N time slots on the first single frequency for the other of inbound and outbound transmissions for the full duplex individual call between the assigned second repeater and the first subscriber unit; and cause a grant message to be transmitted, via the transceiver and the first repeater, to the first subscriber unit indicating the assigned first single frequency and assigned first and second time slots. - View Dependent Claims (18, 19, 20)

21. A method for enabling full duplex individual calls in repeater mode between a dispatch console and a subscriber unit in a N:
- 1 slotting ratio time division multiple access (TDMA) radio system, the method comprising;
receiving, at a radio controller, a request for a full duplex individual call from a dispatch console identifying a first subscriber unit as a target of the full duplex individual call; determining, by the radio controller, whether to grant or deny the request; and responsive to determining to grant the request; assigning, by the radio controller, a first time slot of the N time slots on a first single frequency for one of inbound and outbound transmissions for the full duplex individual call between an assigned first repeater and the first subscriber unit and a second time slot of the N time slots on the first single frequency for the other of inbound and outbound transmissions for the full duplex individual call between the assigned first repeater and the first subscriber unit; and causing, by the radio controller, a grant message to be transmitted to the first subscriber unit indicating the assigned first single frequency and assigned first and second time slots. - View Dependent Claims (22, 23)
