The power consumption of a mobile station is reduced according to the conditions of use by a user without stopping packet communication necessary for the user. In a program for a base station apparatus, a request for establishing radio connection and information indicating the conditions of use of the mobile station apparatus are acquired from the mobile station apparatus (step S). When the information indicating the conditions of use indicates the use of the mobile station apparatus, a first timer is set for a relatively long time whereas when the information indicating the conditions of use indicates the non-use of the mobile station apparatus, the first timer is set for a relatively short time. When the transmission of a packet to the mobile station apparatus is completed (step S), the first timer is started up (steps Sand S), and when the first timer expires, a control signal is transmitted to the mobile station apparatus (step S) to interrupt the radio connection to the mobile station apparatus (step S).

Program and base station apparatus

A wireless communication system is provided in which a plurality of MTC devices can connect to a base station device efficiently. Each of MTC devices in group A that transmits data to the base station device using a predetermined application format is allocated first radio resource common in group A. The MTC device transmits an access request signal to the base station device using the first radio resource. The base station device receives the request signal from the MTC device. The base station device allocates second radio resource common in group A to the MTC device. The MTC device transmits data to the base station device using the second radio resource.

Wireless communication system

A mobile station is provided to which multimedia broadcast/multicast service can be applied also during carrier aggregation. A mobile station communicates with a base station by carrier aggregation using a plurality of component carriers having different frequency bands. The mobile station receives contents in MBMS from the base station using at least two component carriers of a plurality of component carriers. The mobile station causes a display to display the received contents.

Mobile station, base station, communication system, display control method, communication control method, and program

There are provided a terminal device capable of reducing power consumption when a plurality of applications perform data communication, a communication method for the terminal device, a program executed by the terminal device, a storage medium having the program stored thereon, and a radio communication system including the terminal device. The terminal device includes: application running means for running a plurality of applications adapted to perform data communication; communication means for performing a procedure necessary for activating data communication to make a state transition to a communicable state, and performing data communication; and management means for controlling execution of subsequent data communication before a transition from the communicable state to another state.
