Description

Network device, wireless communication system, and wireless communication method Technical Field The present disclosure relates to a network device, a wireless communication system, and a wireless communication method, which envisage the use of AIML technology in slice (Slicing) technology. Background The third Generation partnership project (3 GPP: registered trademark) has standardized the fifth Generation mobile communication system (also referred to as 5G, new Radio (NR), or Next Generation (NG)). Moreover, in 3GPP, standardization of the next generation called Beyond 5G, 5G Evolution (5G Evolution), or 6G is also advancing. Further, in 3GPP Release-19, a technique (slicing technique) of virtually separating a network for each service has been studied (for example, non-patent document 1). Prior art literature Non-patent literature Non-patent document 1："Moderator's summary for Rel-19 RAN3 topic AI/ML for NG-RAN", RP232623, 3GPP TSG RAN Meeting #101, 3GPP, 2023, month 9 Disclosure of Invention In addition, in 3GPP Release-17, a framework (AIML (ARTIFICIAL INTELLIGENCE MACHINE LEARNING: artificial intelligence machine learning) technique) of a RAN (Radio Access Network: radio access network) realized by AI (ARTIFICIAL INTELLIGENCE: artificial intelligence) is proposed. Under such circumstances, the inventors have conducted intensive studies and as a result, have found that it is necessary to specify what information should be exchanged between nodes, assuming that AIML technology is used in the slicing (Slicing) technology. Accordingly, the present disclosure has been made to solve the above-described problems, and an object thereof is to provide a network device, a wireless communication system, and a wireless communication method capable of performing appropriate communication of information predicted using the AIML technique when the AIML technique is used in the slicing technique. The disclosed summary is a network device provided with a control unit that controls communication of a virtual network using one or more services in a network, and a transmission unit that transmits prediction information associated with the communication to other network devices. The disclosed summary is a wireless communication system provided with a terminal and a network device provided in a network, wherein the network device is provided with a control unit that controls communication of a virtual network using one or more services in the network, and a transmission unit that transmits prediction information associated with the communication to other network devices. The disclosed summary is a wireless communication method that includes the steps of controlling communication of a virtual network using one or more services in a network, and transmitting prediction information associated with the communication to other network devices.
