Abstract: A control unit 19 switches four antennas 111 to 114 at predetermined time intervals, receives signals from an LTE base station 2 using four receiving antennas 111 to 114, and receives signals from a GSM base station 3 using the four antennas 111 to 114. The control unit 19 determines the reception level in a cell 2c of the LTE base station 2 on the basis of signal strengths detected by a received signal detector 14p when signals are received from the LTE base station 2 using the four antennas 111 to 114. In addition, the control unit 19 determines the reception level in a cell 3c of the GSM base station 3 on the basis of four signal strengths detected by the received signal detector 14p when signals are received from the GSM base station 3 using the four antennas 111 to 114.

Abstract: A wireless communication terminal has a first wireless communication unit which performs data communication via a first wireless communication system and a second wireless communication unit which performs voice communication via a second wireless communication system. When an instruction of starting a voice communication is given, a temporal withdrawal process is started to the first wireless communication system, and an acquiring process of the second wireless communication system is started. After the voice communication ends, until a predetermined time elapses, an acquiring state of the second wireless communication system by the second wireless communication unit is continued. After the predetermined time has elapsed, the acquiring state of the second wireless communication system is cancelled, and a temporal withdrawal cancelling process is started to the first wireless communication system.

Abstract: Reception of a list including information on a content not receivable at a current location is avoided in acquiring a multicast content list. A portable terminal searches a wireless base station which can communicate with the portable terminal at a current location thereof, and transmits available sector identification information for identifying the searched wireless base station to a content information server. Based on the available sector identification information and multicast detailed information on a content distributed by the wireless base station, the content information server transmits a list of contents receivable at the current location of the portable terminal to the portable terminal. The portable terminal selects a content from the content list in accordance with user's manipulation, and makes transition to a channel where the selected content is distributed based on the multicast detailed information.

Abstract: A mobile communication terminal includes a proximity wireless communication unit and a control command generating unit. The proximity wireless communication unit performs wireless communication directly with another mobile communication terminal present in a communicationable range. When the proximity wireless communication unit is capable of communicating with another mobile communication terminal, the control command generating unit generates a control command which is associated with an internal state and which is for controlling another mobile communication terminal, and transmits the control command to another mobile communication terminal through the proximity wireless communication unit.

Abstract: When the user of the mobile communication terminal produces the originating operation while in the idle state with the wireless system C, the control section acquires the input of the user of the mobile communication terminal via the key input section (step 302) and acquires, through the present position acquisition section, area identification data of an area L where it is placed in the idle state (step 304). The control section makes a reference to the table of connection scores held in the storage section and acquires a connection score p for the system A corresponding to the area L (step 306). Next, the control section judges the start of origination to the system A by using the connection score p (step 308).

Abstract: A communication terminal comprising a video reproduction device configured to carry out a video reproduction, a communication device configured to carry out a communication; and a reproduction-end-time acquisition device configured to acquire an end time of the video reproduction carried out by said video reproduction device. When an incoming communication arrives from a communication partner terminal in the course of the video reproduction carried out by said video reproduction device, the communication partner terminal is informed of the end time of said video reproduction. The communication partner terminal is external to the communication terminal.

Abstract: First, the strength A of a first pilot signal currently transmitted by a base station and strength B of a second pilot signal transmitted by a base station other than the foregoing base station are measured, the correction value D of a handoff threshold value according to the multicast service availability and radio configuration information of the multicast content is obtained, and handoff threshold value C is obtained, as well. Next, if the difference between the strength B of the second pilot signal and the strength A of the first pilot signal is greater than the sum of the handoff threshold value C and the correction value D, the idle handoff is started. Through this, idle handoff to neighbor base stations delivering the same multicast content is facilitated and idle handoff to other base stations is made difficult.

Abstract: When an incoming voice call is detected, a mobile phone 100 judges whether an application that coordinates multicast service and unicast communication is running. If the application is not running, the user is notified of incoming voice calls. On the other hand, if in an application running state, priority mode setting information 1041 is referenced and data cell priority mode is judged. If judged to be in data call priority mode, data communication is continued without notifying the user of the reception of incoming voice calls. On the other hand, if judged to be in voice call priority mode, the user is notified of incoming voice calls.

Abstract: First, a control device determines a reproduction-display device, from which the control device has been able to obtain neighborhood device information via a short-range wireless communication section, to be located in the neighborhood of the control device, and registers this reproduction-display device to neighborhood determination information. Next, the control device detects the reproduction-display devices connected to a network, to which a content server is connected, using a network communication section and registers these reproduction-display devices to reproduction device registration information. The reproduction-display device, which is registered in both of the reproduction device registration information and the neighborhood determination information, is designated by priority, and reproduces and displays content.

Abstract: A controller of the communication terminal identifies, after power is turned on, whether or not to use a cellular phone communicating unit or a wireless LAN communicating unit based on communication system information stored beforehand in a storing unit. When the identification is complete, the controller initializes the cellular phone communicating unit, and, according to results of the identification, causes the cellular phone communicating unit to enter standby state or sleep state. Next, the controller initializes the wireless LAN communicating unit, and, according to results of the identification, causes the wireless LAN communicating unit to enter standby state or sleep state. When an application which using a wireless communicating unit in sleep state is launched, the controller causes that wireless communicating unit to enter standby state from sleep state.

Abstract: A wireless LAN device determines whether there is a necessity to search for a base station based on base station information as to a currently associated first base station, and selects all or a part of base station search conditions stored in advance to search for the base station when there is the necessity for searching the base station. When detecting at least one base station, the wireless LAN device determines whether there is a necessity to execute a handover based on base station information of each of the detected base station and the first base station. If the handover is necessary, the wireless LAN device determines the second base station from the base stations and associates the wireless LAN device with the second base station.

Abstract: A mobile communication terminal performs an antenna picture display according to the received signal power measured by a received signal measurement means and the base station transmission conditions acquired by a base station transmission condition acquisition means. Therefore, the display of a large number of antenna pictures regardless of a high error rate at the receiving-end does not occur and the user does not become confused. As a result, the antenna picture display method when using multicast services is improved and user-friendliness is enhanced.

Abstract: In a multimode mobile station capable of communicating with a plurality of cellular systems where a current cellular system which the mobile station has acquired and a cellular system which the mobile station tries to access differ, access-failure information is stored at access failure time. The access-failure information includes any one of, or the combination of information on access failure such as access-system type, access time information, access location information, access failure reason, number of access failures, etc. Since an access cellular system is selected on the basis of the stored access-failure information, even when a current cellular system which the mobile station has acquired and a cellular system which the mobile station tries to access differ, it is possible to shorten re-acquisition time and to reduce power consumption.

Abstract: When a voice incoming call occurs during multicast content playback, a control section interrupts multicast content playback after storing the multicast service execution status at that time point in a storage section. After a voice call is completed, the control section confirms whether or not the multicast content for which playback has been interrupted can be distributed at that location and, when distribution is possible, confirm whether or not the multicast content has been actually distributed. Then, if in distribution, the control section resumes multicast content playback.
