The present invention provides a mobile terminal, resource allocation manager and communication control method for sustaining the standby time to a time equivalent to the standby time of a communication device in which only a single radio interface is activated, without missing an opportunity of radio communication under good communication conditions.A mobile terminal 1 comprises a first communication section 101, a second communication section 102, a receiving activation section 103 for activating a second receiving function for the second communication section 102 as a result that the first information is received by the first communication section 101, an information transmission section 104 for sending terminal identification data of the mobile terminal 1 as a result that the second receiving function is started up by the receiving activation section 103, and a switching request section 105 for selecting the first communication section 101 or the second communication section 102 as a communication section for receiving information sent by the radio communication station which received the terminal identification data from the information transmission section 104, based on the terminal identification data, and switching a receiving function to be activated.
