1. A base station device comprising a control circuit that performs operations including:
receiving an acquisition request from an application function node, the acquisition request comprising a request for acquiring beam information related to a packet data unit (PDU) session currently established with a terminal device; and
in response to the acquisition request, transmitting, to the application function node, beam group information that includes the beam information, the beam group information being associated with the PDU session currently established with the terminal device,
wherein, in response to the acquisition request, the control circuit also transmits a request to a session management function (SMF) node for one of:
a release of a second PDU session managed by the SMF node, the second PDU session using a beam that interferes with a beam used in the PDU session currently established with the terminal device, or
a stop of traffic in the beam that interferes with the beam used in the PDU session currently established with the terminal device,
wherein the PDU session currently established with the terminal device is one of a plurality of PDU sessions managed by the base station device, and
wherein the control circuit:
acquires subscriber information identifying a subscriber corresponding to each of the plurality of PDU sessions managed by the base station device, and
associates the subscriber information with beam information for each of the plurality of PDU sessions managed by the base station device, and
wherein the beam information includes subscriber information corresponding to the PDU session currently established with the terminal device, and
wherein the request for the one of the release of the second PDU session or the stop of traffic comprises subscriber information corresponding to the second PDU session.
