Abstract

Systems, methods, devices, and computer program products are provided. Operations thereof include sending, by a first system and to a user equipment, an activation notification that activates a dangerous area and causes the user equipment to increase a reporting granularity corresponding to a location of the user equipment. The dangerous area corresponds to an area that includes a vehicle operating therein. The reporting granularity is increased relative to a first reporting granularity. Operations include receiving, from the user equipment, location reporting data that is provided at the increased granularity and sending, to a second system, a first notification that corresponds to determining that the Vulnerable Road User (VRU) will be in the dangerous area.

Claims (38)

1. A method performed by a user equipment (UE), the method comprising:

communicating with a first system via a radio access network;

receiving, from the first system, predefined dangerous zones that include a dangerous area, wherein receiving the predefined dangerous zones is performed using low priority data transfers for the user equipment to preload the predefined dangerous zones; and

increasing a frequency at which a Global Navigation Satellite System (GNSS) is accessed responsive to the user equipment entering the dangerous area, the dangerous area corresponding to an area that includes a vehicle operating therein, wherein an increase in GNSS access frequency provides an increased location data.

2. The method of claim 1 , further comprising sending, to the first system, a request for radio resources to provide the increased location data relative to data that was provided before increasing the frequency at which the GNSS was accessed.

3. The method of claim 1 , further comprising activating the dangerous area responsive to receiving a notification.

4. The method of claim 3 , wherein the notification is received from a vehicle user equipment or wherein the notification is received from the first system.

5. The method of claim 1 , further comprising sending a notification to a vehicle user equipment.

6. The method of claim 1 , further comprising:

receiving, from the first system, a first configuration message corresponding to the dangerous area; and

activating the dangerous area and increasing a reporting granularity corresponding to a location of the user equipment in response to receiving the first configuration message.

7. The method of claim 1 , further comprising:

receiving, from the first system, a second configuration message corresponding to the dangerous area; and

deactivating the dangerous area and decreasing a reporting granularity corresponding to a location of the user equipment in response to receiving the second configuration message.

8. The method of claim 1 , further comprising the increasing the frequency that the global navigation satellite system (GNSS) is accessed is responsive to receiving a first configuration message.

9. The method of claim 8 , further comprising decreasing a frequency that a GNSS is accessed responsive to receiving a second configuration message.

10. The method of claim 1 , wherein a size of an activated portion of the predefined dangerous zones is based on a speed of the vehicle.

11. A user equipment (UE) comprising:

a transceiver that is configured to communicate with a first system via a radio access network; and

a processor that is coupled to the transceiver and that is configured to perform operations comprising:

receiving, from the first system, predefined dangerous zones that include a dangerous area, wherein receiving the predefined dangerous zones is performed using low priority data transfers for the user equipment to preload the predefined dangerous zones; and

increasing a frequency at which a Global Navigation Satellite System (GNSS) is accessed responsive to the user equipment entering the dangerous area, the dangerous area corresponding to an area that includes a vehicle operating therein,

wherein an increase in GNSS access frequency provides an increased location data.

12. A method performed by a network node, the method comprising:

communicating, using a first network application, with a user equipment, to cause the user equipment to activate a dangerous area and to increase a reporting granularity corresponding to a location of the user equipment, the dangerous area corresponding to an area that includes a vehicle operating therein, the reporting granularity is increased relative to a first reporting granularity, wherein the dangerous area is included in predefined dangerous zones provided to the user equipment via low priority data transfers for the user equipment to preload the predefined dangerous zones;

receiving, from the user equipment, location reporting data that is provided at the increased granularity; and

communicating, between the first network application and a second network application, a first notification that corresponds to determining that the user equipment is in the dangerous area, and the second network application is configured to send a vehicle notification to the vehicle to avoid a collision.

13. The method of claim 12 , further comprising determining, by the first network application, coarse location data of the user equipment using network only measurements, wherein the network only measurements comprise: reference signal received power measurements from surrounding communication network cells or beamformed reference signals from one or more base stations.

14. A method performed by a first system, the method comprising:

sending, to a user equipment, predefined dangerous zones that include a dangerous area, wherein receiving the predefined dangerous zones are sent to the user equipment using low priority data transfers for the user equipment to preload the predefined dangerous zones; and

sending, to the user equipment, an activation notification that activates the dangerous area and causes the user equipment to increase a reporting granularity corresponding to a location of the user equipment, the dangerous area corresponding to an area that includes a vehicle operating therein, wherein the vehicle comprises a vulnerable road user (VRU) and the reporting granularity is increased relative to a first reporting granularity;

receiving, from the user equipment, location reporting data that is provided at the increased granularity; and

sending, to a second system, a first notification that corresponds to determining that the VRU will be in the dangerous area.

15. The method of claim 14 , further comprising, before sending the first notification to the second system, anonymizing the first notification to remove VRU specific data therefrom, wherein an anonymized first notification is sent to the vehicle via the second system.

16. The method of claim 14 , further comprising sending a second configuration message to the user equipment that causes the user equipment to deactivate a previously identified dangerous area and to decrease a reporting granularity corresponding to a location of the user equipment.

17. The method of claim 14 , wherein a first configuration message further causes the user equipment to increase a frequency that the global navigation satellite system (GNSS) is accessed, and wherein the second configuration message further causes the user equipment to decrease a frequency that the Global Navigation Satellite System (GNSS) is accessed.

18. The method of claim 14 , wherein sending, to the user equipment, the activation notification that activates the dangerous area is performed responsive to detecting that the user equipment is proximate the dangerous area and that conditions corresponding to activating the dangerous area are present, wherein conditions include information corresponding to the vehicle.

19. The method of claim 14 , further comprising: sending a second configuration message to the user equipment that causes the user equipment to deactivate a previously identified dangerous area and to decrease a reporting granularity corresponding to a location of the user equipment in response to detecting that the user equipment is not proximate the dangerous area.
