A communication control device, includes a terminal information acquisition unit which acquires terminal-related information including communication service information relating to a communication service executed, and network information relating to a network, a selection unit which selects, among a plurality of combinations of networks each of which can be used by each of a plurality of communication services, a combination of networks having a smallest total communication cost to be charged for each of the plurality of communication services in each of the plurality combinations of networks, on the basis of the terminal-related information, and network-related information including communication cost information, and communication bandwidth information, and a network control unit which executes a network control such that the networks used respectively by each of the plurality of communication services are the selected combination of networks.

Communication control device, communication control system and communication control method

A frequency deviation is to be estimated in a wireless communication system in which a control data transmission channel and a user data transmission channel are allocated to different frequency bands. An estimation result using a reference signal for modulation in the user data control channel and an estimation result using a reference signal for estimating channel quality may be combined, according to an estimation result using a reference signal for modulation in the control data transmission channel, in order to modify the allocation period of the reference signal for estimating channel quality depending on the estimation result.
