An LTE system includes an eNB 200-2 configured to support D2D communication which is one of LTE communication schemes and in which communication is directly performed between proximal devices, and an eNB 200-1 included in an LTE network. A communication control method includes: a step S11 of requesting, by the eNB 200-2, an allocation of a D2D communication resource to the eNB 200-1; a step S12 of allocating, by the eNB 200-1, on the basis of the request from the eNB 200-2, the D2D communication resource from a specific frequency band shared by a plurality of mobile network operators or a plurality of communication systems, to the eNB 200-2; and a step S16 of performing, by the eNB 200-2, the D2D communication by using the D2D communication resource allocated from the eNB 200-1.
