Abstract
In a communication system constituting a first core network and a second core network, a location management device deployed in a first core network initiates a switching procedure between the core networks. In the switching procedure, the second core network is selected by MME selection of a base station device, allowing a terminal device to connect to the second core network. This configuration provides a communication control method and the like for enabling a terminal device to switch between core networks in a communication system in which multiple core networks are overlaid.
