摘要:
A network element or server that manages name, address and identifying information of network devices that contain at least one Bluetooth interface is described. A Bluetooth Device Address may be queried by a first network device of a second network device to the server and the server may provide additional name, address and identifying information on the queried second network device to the first network device such that the first network device may establish a preferred connection with the second network device.

A large amount of user information is transmitted with good efficiency by means of a high-speed downlink by making transmission rates of an uplink circuit and a downlink asymmetrical. The radio communication system includes a plurality of base stations, a plurality of terminals, an uplink established between each of the base stations and each of the terminals for the purpose of radio transmission of prescribed information from a terminal to a base station, and a downlink circuit established between each of the terminals and each of the base station for the purpose of radio transmission of prescribed data from a base station to a terminal. This radio communication system has a low-speed transmitting means, provided at the terminal, which transmits a radio signal at a relatively low transmission rate to an above-noted base station via the above-noted uplink, a low-speed receiving means, provided at the base station, which receives a radio signal sent at a relatively low transmission rate from the terminal via the uplink, a high-speed transmitting means, provided at the base station, which transmits a radio signal at a relatively high transmission rate to an above-noted terminal via the above-noted downlink, and a high-speed receiving means, provided at the terminal, which receives a radio sent at a relatively high transmission rate from the base station via the downlink.

摘要:
In a radio communication system having narrow-band up- and down-link radio channels and a wide-band down-link radio channel, when a radio terminal is to receive data through the wide-band down-link radio channel, the narrow-band up- and down-link radio channels are assigned to the radio terminal in advance. With this operation, communication an be performed by using the wide-band down-link radio channel. In addition, the narrow-band up- and down-link radio channels can be used as radio channels for performing control to efficiently transmit data by using the wide-band down-link radio channel.
摘要:
In a radio communication system, communication for sending data from a transmitting station to a receiving station and communication for transmitting re-send data from the transmitting station to the receiving station according to the re-send request transmitted from the receiving station to the transmitting station are done on different occasions of communication. Hence, in the applications not requiring real time service, this re-send control method does not spend the power and radio resources wastefully, and by effectively utilizing the system resources and lowering the power consumption, the battery of the terminal may be reduced in size, so that the portability of the terminal may be enhanced. Further, the radio communication system has a high speed down-link channel and a low speed down-link channel, data to be transmitted from a base station to a terminal is classified into primary data and secondary data, the primary data is transmitted by the high speed down-link channel, and the secondary data is transmitted by the low speed down-link channel.

摘要:
A portable terminal includes a first store for storing a first physical address including a serial number of the terminal, a second store for storing a first logical address including a subscriber's telephone number, a third store for storing a second physical address of a hardware used for computer communication, a fourth store for storing a second logical address corresponding to the second physical address, an interface for radio LAN, and an interface for PHS system. When a call is originated, a first channel is connected by using the first physical address and the first logical address. The second physical address and the second logical address are transmitted to the network from the call originator's terminal through the first channel, thereby setting in a state enabling communication between computers, and necessary data is transmitted to the call originator's terminal through a second channel by communication between computers.
