Communication system, base station, communication method, and non- transitory computer readable medium storing program

A radio access network node comprising a processor configured to:

• receive, from a core network node, a first identifier identifying a Dedicated Core Network,
• receive, from a terminal, a second identifier identifying a Dedicated Core Network, and
• select a core network node based on the first identifier and the second identifier.

A core network node comprising a processor configured to:

• provide, to a radio access network node, a first identifier identifying a Dedicated Core Network so that the radio access network node receives, from a terminal, a second identifier identifying a Dedicated Core Network, and
• select a core network node based on the first identifier and the second identifier.

A terminal comprising a processor configured to:

• provide, to a radio access network node, a second identifier identifying a Dedicated Core Network so that the radio access network node receives, from a core network node, a first identifier identifying a Dedicated Core Network, and
• select a core network node based on the first identifier and the second identifier.
