Abstract:
Provided are a communication control device and a selection device that perform communication control that suppresses the occurrence of congestions, such as one that does not satisfy a predetermined bitrate requirement. An AMF 100 is provided with: a receiving unit 101 that receives congestion information in each of a plurality of RANs 310 that are communication connection devices; a notification processing unit 102 that provides notification of the congestion information to an E2E slice selection/control apparatus 400 used for selecting one RAN 310 from the group of the RANs 310 and thereby causes the E2E slice selection/control apparatus 400 to store the congestion information in each RAN 310; a connection processing unit 104 that, upon reception of a PDU Session Establish Request that is a connection request from a RAN 310, transmits a slice selection request to the E2E slice selection/control apparatus 400; an identification information receiving unit that receives, as a response to the slice selection request, the identification information of a selected RAN slice 300 and the identification information indicating a RAN 310 selected on the basis of the congestion information; and a communication processing unit that performs a communication connection processing using the RAN 310 in the RAN slice 300 indicated by the identification information.
