A radio communication unit performs communication using a first frequency band or a second frequency band. A control unit allows a connection to an access point in the first frequency band when a signal level of a received signal of the first frequency band which is received from the access point exceeds a first threshold. When the connection to the access point in the first frequency band is established and when the signal level exceeds a second threshold greater than the first threshold, the control unit starts a search for an access point in the second frequency band.

Communication system, terminal apparatus and method

A mobile communication device includes a wireless communication interface and a processor. The wireless communication interface runs a first scan for searching for one or more access points. The processor determines whether, by the first scan, a plurality of access points with the same identification information have been detected on different channels. Based on results of the determination, the processor alters the method of a second scan to be run after a connection to an access point.

Mobile terminal apparatus, control method, and computer product

A wireless communication interface measures a signal level of a received signal from an access point. A control unit calculates connection time with the access point to which a mobile communication device is connected. The control unit associates a first connection threshold or a second connection threshold that is larger than the first connection threshold with the access point on the basis of the connection time. After calculating the connection time, when the mobile communication device is not connected to the access point, the control unit determines whether to connect the mobile communication device to the access point on the basis of a comparison between the signal level and the first connection threshold or the second connection threshold associated with the access point.

A mobile terminal device, when detecting that a display state of a screen transitions from non-display to display, starts a scanning operation of searching for an access point. If an access point of the same access point identification information is found successively a given number of times N, the mobile terminal device suspends the scanning operation of searching for an access point. If movement of the mobile terminal device is detected subsequent to suspending the scanning operation of searching for the access point, the mobile terminal device resumes the scanning operation for the access point.

Mobile terminal device, control method, and computer product

A mobile terminal device includes a processor that connects to a base station; connects to a network through an access point; and detects transition from a non-display state to a display state; and a storage device that stores connection history information correlating area identification information identifying a communication area of the base station, and access point identification information identifying an access point through which connection to the network has been made in the communication area. The processor, when detecting the transition in a communication area of a first base station, starts searching for an access point in the communication area of the first base station after a predetermined period elapses, and determines whether an entry including first area identification information of the first base station is retrieved from the connection history information; and after the predetermined period elapses, performs control to connect to the network, based on a determination result.

An information terminal apparatus includes a memory and a processor. The memory stores information indicating a front operating system. The processor runs a first virtual machine that executes a first operating system. The processor runs a second virtual machine that executes a second operating system. The processor controls user interface of the information terminal apparatus by executing the front operating system. The processor detects, by referring to the information stored in the memory, that the front operating system is changed from the first operating system to the second operating system. The processor notifies, upon the detection, the first virtual machine of a first notification indicating that the user interface stops. The processor notifies, upon the detection, the second virtual machine of a second notification indicating that the user interface restarts.

A wireless communication terminal comprises a detection section, an acquisition section and a control section. The detection section detects activation of a voice telephone service application. The acquisition section acquires wireless station information transmitted from a wireless station that is a communication partner. The control section is set so as to ensure that a wireless receiver that receives wireless station information from the wireless station is always put in the ON condition when activation of the voice telephone service application is detected by the detection section. The control section sets the reception processing interval for which wireless station information is received and processed by the wireless receiver to a first interval in accordance with the wireless station information acquired by the acquisition section. The first interval is a time interval in which reception of voice telephone service incoming calls during standby is enabled.
