摘要： A host providing system includes a physical host network switch which determines permission and non-permission of communication on the basis of whether or not information pieces indicating users correlated with information indicating a transmission source and information indicating a transmission destination included in communication data from a physical instance match each other, and controls the communication data on the basis of a determination result. Accordingly, since only communication between instances of the same user is permitted, and thus communication from a physical instance is appropriately controlled, it is possible to ensure security in the system.

摘要： The disclosure provides a mobile communication system, a communication control device, a mobility management entity, and a mobile communication method which can avoid a failure in making an emergency call via an IMS when a mobile station connects to a VPLMN. An HSS 100 judges whether or not an emergency call origination via an IMS 500 is supported in the VPLMN, and transmits a signal including an indicator, EM supported or EM not supported, which indicates whether or not the emergency call origination is supported, to an MME 300. The MME 300 receives the indicator from the HSS 100 and transmits, to the UE 20, Attach Accept responding to Attach Request to the VPLMN from a UE 20. Based on the indicator received from the HSS 100, the MME 300 transmits, to the UE 20, Attach Accept including the indicator which indicates whether or not the emergency call is supported.
