TERMINAL APPARATUS, COORDINATOR, AND METHOD FOR MANAGING EMERGENCY EVENTS
First Claim
1. A method for managing an emergency event in a terminal apparatus, comprising:
- determining whether an emergency event occurs;
selecting a channel for transmitting an alarm message indicating occurrence of an emergency event, if the emergency event occurs;
transmitting the alarm message to a coordinator using the selected channel;
determining whether a response message to the alarm message is received, for a predetermined time; and
performing an operation associated with the emergency event if the response message is received.

Abstract
The present invention provides an integrated medium access control for processing respectively separated traffic situation sets. Another aim of the present invention is to optimize power consumption during a poll based operation of the medium access control mechanism. An additional aim of the present invention is to provide a poll-based error recovery mechanism for achieving preferred application reliability through power- and cost-efficient methods. A further aim of the present invention is to provide an in-band wakeup method for a medical implant device in a human body area network. Still a further aim of the present invention is to provide a method for a medical implant device in a human body area network. An even further aim of the present invention is to provide a method for simultaneously accessing a power channel of a poll-based minimum level and operating a plurality of BANs in medical implant communications.

8. A method for managing an emergency event in a coordinator, comprising:
-
transmitting, to a device, a poll message causing the device to transmit data to the coordinator; retransmitting the poll message upon failure to receive data for the poll message; determining whether the number of retransmissions of the poll message exceeds the predetermined maximum number of retransmissions; transitioning to a sleep state for reception of an alarm message indicating occurrence of an emergency event, if the number of retransmissions of the poll message exceeds the maximum number of retransmissions; upon receiving the alarm message, transmitting an acknowledgement message to the device having transmitted the alarm message; and performing an operation associated with the emergency event. - View Dependent Claims (9, 10, 11)

12. A method for managing an emergency event in a coordinator, comprising:
-
determining whether energy greater than or equal to a predetermined threshold is detected, in a sleep state; selecting a channel through channel scanning upon detecting the energy greater than or equal to the predetermined threshold; upon detecting an alarm message indicating occurrence of an emergency event, transmitting an acknowledgement message to a device having transmitted the alarm message; and handling the emergency event.

13. A coordinator for managing an emergency event, comprising:
-
an energy detector for determining whether energy greater than or equal to a predetermined threshold is detected, and triggering a processor being in a sleep state upon detecting the energy greater than or equal to the predetermined threshold; and the processor for transitioning to an on-state if triggered by the energy detector, and upon receiving an alarm message indicating occurrence of an emergency event, transmitting an acknowledgement message to a device having transmitted the alarm message, and handling the emergency event. - View Dependent Claims (14)

15. A coordinator for managing an emergency event, comprising:
-
a transmitter for transmitting, to a device, a poll message causing the device to transmit data to the coordinator; a controller for retransmitting the poll message upon failure to receive data for the poll message, determining whether the number of retransmissions of the poll message exceeds the predetermined maximum number of retransmissions, and transitioning to a sleep state for reception of an alarm message indicating occurrence of an emergency event, if the number of retransmissions of the poll message exceeds the maximum number of retransmissions; and a receiver for receiving the alarm message; wherein upon receiving the alarm message, the controller transmits an acknowledgement message to the device having transmitted the alarm message, by means of the transmitter; and
performs an operation associated with the emergency event. - View Dependent Claims (16, 17, 18)
