In making a switching by hand-over, it takes a shorter time to redecide a radio base station of destination candidate to be connected that is capable of securing a required radio band, even in case the radio base station of destination to be switched to refuses the connection to a radio communication terminal. Therefore, the radio base station is configured to acquire the service band information of another radio base station, and notify the radio communication terminal of the radio base station information of a destination candidate to be connected to, based on the acquired service band information, in case of refusing a connection switching request from the radio communication terminal performing the hand-over.

The invention provides a multilayer printed wiring board including: a power supply wiring layer and a ground wiring layer provided so as to oppose each other via an insulation layer; mounted integrated circuits; and decoupling capacitors mounted in proximity to the integrated circuits and connected between the power supply wiring layer and the ground wiring layer to absorb noise from the integrated circuits. The power supply wiring layer includes through holes for connecting the decoupling capacitors to the power supply wiring layer and has a polygonal form formed by straight lines which link some of the through holes.

A caller number notification synchronized with an incoming signal is disclosed. An analog circuit interface section outputs incoming call signal presence information that shows whether to receive the incoming call signal that has the information indicated at a predetermined position on a highway and outputs the received caller ID to a speech signal path. An analog extension interface section detects the incoming call signal presence information on the highway, detects the caller ID on the speech signal path, generates an incoming call signal based on the detected incoming signal presence information and sends out the generated incoming call signal and the detected caller ID to the analog extension. A system control section connects the analog circuit interface section to the analog extension interface section.

Disclosed is a telephone to be installed in a house or an office and capable of effectively preventing leakage of data stored in or unauthorized use of the telephone. For this end, a security button 15 is provided for inhibiting the use of all or a part of the stored data in or functions of the telephone. The security button 15 enables the user to set the security condition by a single push-down operation or choose desired security levels by continuous operations. An LED may be installed in the security button 15 to emit light in different colors or patterns for respective security levels.

In a wireless communication method of a wireless communication device to which a power management mode of a wireless LAN is applied and to which a parent device communicates, the method includes updating a listen interval of receiving a beacon signal from a parent device to be shorter than a current listen interval in response to a data transmission to the parent device; and periodically increasing the updated listen interval between the time span from the data transmission to a next data transmission, wherein reception of the beacon signal is carried out after switching from a doze state to an awake state.

A cover operation member (41) is movably attached to the base frame to selectively latch and unlatch a platen (21) attached on the cover frame. The cover operation member (41) is in contact with the head bracket (32) so that the thermal head (31) is separated from the platen (21).
摘要:
Unauthorized access from a network to a terminal is prevented. If a signaling packet received from an external terminal contains a virus, the signaling packet is discarded. If the signaling packet does not apparently contains a virus, an unnecessary part is deleted and the signaling packet is transferred to an internal terminal in response to a polling signal. A port number described in a response packet received from the internal terminal is translated to a different port number. If a session packet received from the external terminal does not conform to a predetermined protocol, the session packet is discarded. If the session packet received from the external terminal conforms to the predetermined protocol, a port number is subject to reverse translation and a resultant session packet is transferred to the internal terminal.
摘要:
A CTI system comprises a telephone terminal (12-2) having an ID tag (18-2), a server-connected main unit (11, 13) for controlling the telephone terminal, and an information processing terminal (16-1) having an ID reader and a communication unit (CU). By positioning the ID reader of the information processing terminal and the ID tag of the telephone terminal in close proximity to each other, the ID reader reads ID information of the ID tag in a non-contact manner. The information processing terminal sends the ID information read by the ID reader to the main unit by the use of the communication unit. The main unit associates the information processing terminal with the telephone terminal with reference to the ID information. The main unit is responsive to a request of the information processing terminal and carries out call control for the telephone terminal associated with the information processing terminal.
