1. An apparatus for correlating network data analytics (NDA) information for a device group comprising multiple terminal devices, wherein each terminal device is associated with a group member identifier and the device group is associated with a group identifier, the apparatus being configured as a Network Data Analytics Function (NWDAF) and comprising:
processing circuitry;
memory containing instructions executable by the processing circuitry whereby the apparatus is operative to:
receive, from a network exposure function (NEF), an NDA request comprising a group identifier and an NDA specification of NDA information to be collected;
send, to at least one of a Unified Data Management (UDM), a Binding Support Function (BSF), and a Unified Data Repository (UDR), a group member identifier request comprising the group identifier;
receive, from the at least one of the UDM, the BSF, and the UDR and in response to the group member identifier request, one or more group member identifiers associated with the group identifier;
configure one or more User Plane Functions (UPFs) associated with the group member identifiers in accordance with the NDA specification;
obtain, from the one or more UPFs, NDA information collected for the group member identifiers based on the NDA specification; and
correlate the NDA information collected for the group member identifiers based on their association with the device group.
