Sports monitoring application describes the case of a human being monitored when doing exercise via utilizing wireless signals instead of cameras, or wearable devices. With enhanced privacy preservation, wireless signals that propagated in the 5G system (e.g. between 5G UE and 5G UE, and between the radio access network and device) can be further reused and processed to retrieve the target sensing object's characteristics [48]. In a sports monitoring situation, the target object is human and the target object's characteristic is human body gesture. By comparing the detected body gesture with the correct body gesture when people are doing exercises like sit-ups, and push-ups, this sport monitoring application will give feedback, for example, it can count the number of the exercise e.g. sit-ups, and calculate calories.

The sports monitoring application provider has a service agreement with mobile operator A in country X and mobile operator B in country Y. Mobile operator A in country X and Mobile operator B in country Y has roaming agreements. Bob installs a sports monitoring application on his mobile phone and subscribes to the sensing service with mobile operator A.

1. Bob is a sports fan and does exercise every day. He travels to country Y and gets accommodation in hotel M, where mobile operator B's sensing service is available. Bob triggers the application and selects his favorite sport, sit-up.
2. The sensing request is received by Mobile operator B and Mobile operator B then authorize whether the sensing request can be satisfied or allowed, e.g. by verifying the sensing system availability (infrastructure, sensing modalities), the location of the sensing service, local privacy restrictions, the roaming agreement with Bob's home mobile operator A in country X, the identity of Bob and etc.
3. If the authorization succeeds, mobile operator B authorizes and provides such 5G sensing service to Bob with required performance targets and requirements and Bob pays for the sensing service to mobile operator B.
   • Mobile operator executes sensing measurement process (e.g. micro doppler shift) with the sensing entities (e.g. RAN entities and the roaming UE, or CPE and the roaming UE) to obtain 3GPP sensing data;
   • Mobile operator processes the 3GPP sensing data to derive sensing result and expose it to the application server.
4. If the authorization fails, mobile operator B does not provide such 5G sensing service to Bob and potentially, Bob or the sports monitoring application server will receive the reason of why mobile operator B cannot provide such sensing service.
5. Later, Bob left the hotel to run around the area near the hotel. When Bob runs near a restricted area where sensing service is not allowed, the Mobile operator B revokes the authorization and terminates the sensing service. Potentially, Bob or the sports monitoring application server will receive the reason of why mobile operator B cannot provide such sensing service.

Bob can enjoy the sports monitoring application even when he travels in another country.

Roaming-related authentication and charging may refer to existing requirements as defined in clause 9 of TS 22.261: The following set of requirements complement the requirements listed in TS 22.115. The requirements apply for both home and roaming cases. The 5G core network shall support collection of charging information for alternative authentication mechanisms The 5G system shall be able to generate charging information regarding the used radio resources e.g. used frequency bands.
