1. A base station device to provide data services between a user equipment (UE) and a data network, the base station device comprising:
a memory to store instructions;
a processor configured to receive the instructions from the memory and to perform operations to:
determine a server address of an application server for a session for traffic transmission of a specific data service between a specific application in the UE and the application server;
determine, in real time, that a server address of the specific data service for the UE is changed in a state in which the session for traffic transmission of the specific data service between the specific application in the UE and the application server is established; and
in response to the determination that the server address of the specific data service is changed, transfer address information of the changed application server to the UE in real time such that the UE is to perform traffic transmission of the specific data service between the specific application in the UE and the changed application server using the transferred address information of the changed application server, and
wherein, when a notification of a change of the application server of the specific data service for the UE is provided from a node of a control plane, the processor is configured to transfer the address information of the changed application server via a message transmitted to the UE during a process of performing user plane reconfiguration that adds, removes, or rearranges a node of a user plane that is involved in the session.
