## Abstract

The present embodiments relate to a method in a system, a method in a network device, and a network device. The method includes: acquiring, from an entity, a notification of the occurrence of an accident of a vehicle in an area; requesting a RAN node and a CN node of the mobile operator to provide information regarding the vehicle; receiving from the CN node a combined information including information regarding communication with the vehicle and/or information of interest in said area provided to the core network node from vehicles and/or users, and/or devices present in said area where the accident occurred, and available information regarding the vehicle; and analyzing the received combined information.

## Claims

### Claim 1

A method in a system comprising a network of a mobile operator, one or more entities, and one or more vehicles configured to communicate with the network of the mobile operator, the method comprising:
a network device of the mobile operator acquiring from an entity a notification of the occurrence of an accident of a vehicle in an area;
the network device requesting a radio access network (RAN) node and a core network (CN) node of the mobile operator to provide information regarding the vehicle;
the core network node determining which vehicles and/or users, and/or devices are present in said area where the accident occurred;
the core network node requesting the vehicles and/or users and/or devices to provide information regarding communication with the vehicle and/or information of interest in said area;
the core network node acquiring the requested information;
the core network node combining the acquired information and available information regarding the vehicle; and
the core network node sending the combined information to the network device for enabling the network device to analyze the combined information.

### Claim 2 (depends on 1)

The method according to claim 1, further comprising the network device sending a request to one or more external parties to provide the available information on the vehicle, and the network device acquiring the available information on the vehicle from said one or more external parties.

### Claim 3 (depends on 2)

The method according to claim 2, further comprising the network device analyzing the acquired information and sending to the entity the result of the analysis of the combined information and the result of the analysis of the acquired information from the one or more external parties.

### Claim 4 (depends on 2)

The method according to claim 2, wherein the information to the network device from the one or more external parties is acquired via a Network Exposure Function (NEF) of the mobile operator.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the network device comprises a Network Data Analytics Function (NWDAF) for analyzing the acquired information.

### Claim 6 (depends on 1)

The method according to claim 1, wherein the information regarding the vehicle acquired from the radio access network node and the core network node includes traffic log information of the vehicle which comprises one or more of the following: location information, call information, information on data consumed in or by the vehicle, information on network services used in or for the vehicle, and status of operation of one or more pieces of equipment of the vehicle.
