Rapid transmission of 5G/6G and low-complexity emergency messages
View Patent ↗Disclosed herein are systems and methods for improved, rapid wireless emergency communication in both advanced (5G/6G) and low-complexity (CDMA-CA) networks. Embodiments may provide improved means for preempting other non-emergency communication, delivering an emergency message with sufficient information to enable first-responders to take appropriate action even if no further communication is possible, and for establishing a privileged voice connection following the emergency message. Embodiments may include a hailing-type emergency message configured to alert a base station when the addresses of base station is unknown to the emergency node. With improved speed and reliability of emergency communication, first-responders may begin an appropriate life-saving response without delay and with knowledge of the type and location of the emergency.
1. A local area network (LAN), comprising a base station in signal communication with a plurality of user nodes, wherein:
each user node is configured to: detect an emergency event, determine whether a communication channel is clear, and if the communication channel is clear, transmit an emergency message to the base station;
wait, after determining that the communication channel is not clear, until the communication channel becomes clear;
then monitor the channel for a predetermined listening period; and
then, if no further signals are detected during the predetermined listening period, transmit the emergency message; and wherein
the emergency message indicates a location of the emergency and a type of emergency response desired.
2. The LAN of claim 1 , wherein the emergency message is transmitted according to 5G or 6G technology.
3. The LAN of claim 1 , wherein the location of the emergency and the type of emergency response desired are in human-readable form after demodulation and conversion to alphanumeric symbols.
4. The LAN of claim 1 , wherein the predetermined listening period is shorter than a delay time that other user nodes are required to wait before transmitting.
5. The LAN of claim 1 , wherein the predetermined listening period is shorter than a delay time that the base station is required to wait before transmitting.
6. The LAN of claim 1 , wherein the emergency message includes a code configured to indicate:
whether medical assistance is needed;
whether police assistance is needed; and
whether rescue assistance is needed.
7. The LAN of claim 1 , wherein the emergency message includes a code configured to indicate:
whether the emergency involves a low risk of injury;
whether the emergency involves a likely risk of injury less severe than a loss of limb or vision;
whether the emergency involves a likely risk of severe injury comprising loss of limb or vision; and
whether the emergency involves a likely risk of death.
8. The LAN of claim 1 , wherein the emergency message is further configured to indicate a number of victims involved in the emergency.
9. The LAN of claim 1 , wherein the emergency message is further configured to indicate whether the emergency involves hazards that first responders need to know about.
10. The LAN of claim 9 , wherein the emergency message is further configured to specify the hazards that first responders need to know about.
11. The LAN of claim 1 , wherein the emergency message is further configured to indicate whether a voice link is requested.
12. The LAN of claim 1 , wherein the emergency message is further configured to indicate whether additional information or an additional message is available.
