PROBLEM TO BE SOLVED: To enable the release of a plurality of bearers and reestablishment processing thereof appropriately.SOLUTION: A communication control method in a communication system 1 includes: preparing urgency information related to the release and the reestablishment of an IMS bearer managed by PCRF 20, which is a communication control device, and MME 30; and determining priority on the basis of the urgency information to execute processing related to the IMS bearer. Thus, the release and the reestablishment of the IMS bearer can be executed successively from a call connection in which, for example, an IMS bearer is to be reestablished as soon as possible (the state of an unavailable bearer is to be ended as soon as possible), like an urgent call bearer.SELECTED DRAWING: Figure 1 |
