The ability to quickly locate an individual that is either missing (search and rescue) or is a suspect in an illegal activity (apprehend) is very important for public safety. Statistics show that the quicker a missing person can be found the higher the possibility they can be found in good condition. Similarly for a suspect in an illegal activity, the quicker they can be located the less likely they can hide or commit another illegal activity. These activities can be in both an outdoor environment and indoors. Leveraging the sensing capability of a 3GPP network and integrating the feature with other 5G capabilities (e.g., metaverse, augmented reality, location, network relay, etc.) can provide a huge advantage to public safety. In an outdoor example, an elderly person with Alzheimer's Disease wanders off into the woods and does not know how to return. The longer it takes for public safety to locate this person the more likely they may suffer injuries or medical issues, such as dehydration, cuts, bruises, broken bones, or worse, death. Another example is an individual who robs a bank and escapes into the nearby forest and swamps. The longer it takes to track down and find the individual, the more difficult it becomes and the bigger the risk of them taking hostages, hurting others, or escaping completely. With the density of base station deployments and with large numbers of 5G enabled UE's, the 5G coverage includes a large amount of the territory of most countries. These base station signals and the signals of UE's can also be used to sense the environment for object detection. Assumptions for this use case:

• Trusted third-party applications for interpreting and presenting the data to public safety is required,
• Devices must be trusted and communicate information togethers; and
• Precision 3-axis location is needed.

An indoor example would be a firefighter entering a building with limited or no visibility using sensing integrated with firefighter heads-up displays/UEs (metaverse/AI/ML) sensing can better allow the firefighters to locate possible people trapped inside and allow them a better view of the rooms as they work through the building. Indoor 5G coverage can be challenging but leveraging features like UE-to-UE relay, UE-to-Network Relay, UE-to-Network multi-hop relay and UE-to-UE multi-hop relay and allowing the devices to work together can provide good coverage and capability to provide indoor sensing services in this challenging environment. Assumptions for this use case:

• The use of UE-to-Network Relay and UE-to-UE relay can provide a more reliable connectivity.
• Devices must be trusted and communicate information togethers; and
• Precision 3-axis location is needed.

1. Operator A's network supports sensing capability with their base stations and have 3GPP sensing enabled UEs on their network.
2. Local public safety officials have a relationship with Operator A allowing them to access the networks sensing capability and service.
3. Appropriate security and privacy requirements are in place between the operator and the public safety organization.

1. Public safety is notified of a need to search for an individual. This could be either a search and rescue, or an apprehend scenario and could involve both indoor and outdoor environments.
2. Operator A's network is 3GPP sensing enabled and public safety's UEs are 3GPP sensing enabled.
3. Public safety personnel begin searching for the individual using both traditional methods, UAVs and UE's with 3GPP sensing capabilities.
4. Depending on coverage there may be a need to leverage indirect network connections.
5. Using the 3GPP sensing data and non-3GPP sensing data public safety can quickly locate the person of interest.
6. The individual is located using the combinations of capabilities.

The individual is located faster than without 3GPP sensing capability. The additional harm that might have occurred to the individual or community is avoided.
