NOTIFICATION OF DISASTER CONDITION AND ALTERNATIVE PLMNs - A simplified explanation of the abstract
This abstract first appeared for US patent application 18035428 titled 'NOTIFICATION OF DISASTER CONDITION AND ALTERNATIVE PLMNs
Simplified Explanation
The patent application describes a system and method for notifying network nodes and user devices about disaster conditions and providing alternative mobile network options. Here are the key points:
- The method involves a User Equipment (UE) responding to a disaster condition in a first mobile network (PLMN).
- If the first PLMN is not available due to the disaster, the UE determines if a second PLMN is available for disaster roaming.
- If a second PLMN is available, the UE attempts to register with it to receive service during the disaster.
- This allows the UE to be informed about the failure of its current PLMN due to a disaster and enables it to receive service from an alternative PLMN that would not be accessible under normal conditions.
Potential applications of this technology:
- Emergency response systems: The system can be used to notify emergency response teams and users about disaster conditions and provide alternative mobile network options for communication during emergencies.
- Disaster management: The technology can assist in coordinating disaster management efforts by ensuring uninterrupted communication services for first responders and affected individuals.
- Public safety: The system can enhance public safety by enabling users to quickly switch to alternative mobile networks in case of network failures during disasters.
Problems solved by this technology:
- Lack of communication during disasters: The technology addresses the issue of network failures during disasters by providing alternative mobile network options for users to stay connected.
- Limited access to services: Under normal conditions, certain PLMNs may not allow users to access their services. This technology enables users to receive service from such PLMNs during disaster situations.
Benefits of this technology:
- Improved emergency communication: The system ensures that users have access to communication services even when their primary network is unavailable.
- Enhanced disaster response: By providing alternative network options, the technology facilitates better coordination and communication among emergency response teams during disasters.
- Increased public safety: Users can quickly switch to alternative networks, ensuring that they can reach out for help or stay informed during critical situations.
Original Abstract Submitted
Systems and methods for enabling notification of disaster conditions and alternative Public Land Mobile Networks (PLMNs) to network nodes are disclosed. In one embodiment, a method performed by a User Equipment (UE) for responding to a disaster condition in a first PLMN, comprises determining that a first PLMN is not available; determining that a second PLMN is available for disaster roaming; and attempting to register with the second PLMN, responsive to determining that the first PLMN is not available due to the disaster condition and determining that a second PLMN is available for disaster roaming. In this way, a UE is informed of the failure of its currently used PLMN due to a disaster condition and a service may be provided in another PLMN, where the UE under normal conditions may not be allowed to receive a service from the second PLMN.
