Filed: 1994-08-23
Abstract: PURPOSE: To reduce the transmission cost of the control information between a mobile station and the communication network of a macrocell by sending also the control information generated when the mobile station is included in the microcell to the communication network via the macrocell when the control information is sent to the communication network of the microcell from the mobile station. CONSTITUTION: A macrocell C consists of a radio base station B which is connected to a 1st communication network A, and a microcell F consists of a radio station E which is connected to a 2nd communication network D of an enterpriser different from that of the network A. The macrocell C is overlaid on the microcell F. When a mobile station G, i.e., a subscriber of the network A is included in the microcell F, the station G talks with another subscriber via a base station E as shown by an arrow J. In the conventional technology, the information received from the station G is sent to the network A via the station E and the network D as shown by an arrow H and the extra cost is needed by intervention of the microcell F.  In this example, however, the station G sends the control information to the network A of the self station via the station B placed on the side of the macrocell C as shown by an arrow I. Thereby the equipment cost is reduced for the microcell F since the station E is not used.

Title: Linear amplifying circuit
Inventor: OSHIO UMEO
IPC: H03G1/00
Filed: 1982-11-12
Abstract: PURPOSE:To avoid the DC deflection which is generated during gain control by providing a voltage control transistor TR to compensate automatically a voltage drop with the collector current of a pair of differential TRs for gain control. CONSTITUTION:Transistors TRQ1a and Q1b form the 1st differential amplifying circuit for input signal; while TRQ2a-Q2d form the 2nd differential amplifying circuit for gain control. At the same time, a TRQ3 is a TR for voltage control and detects a voltage drop due to the collector currents of TRQ1a and Q1d produced by R/2 having 1/2 resistance value of a resistance R and then controls the voltage of the collector current flowing into TRQ2b and Q2c. Here V0= 1/2RI+VBE is satisfied, where V0 shows the voltage difference between a power supply VCC and the collectors of TRQ2b and Q2c, VBE is the base-emitter voltage of the TRQ3 and I is the current of a constant current source I respectively. Thus it does not depend on the gain control input signal. In such a way, it is possible to eliminate the deflection due to the DC component of a gain control input signal of the output signal without using any complicated constitution.
