摘要： A printed circuit board and a manufacturing method of the same. The method includes forming a circuit board by selectively positioning a heat release layer among multiple insulation layers that have circuit patterns formed on their surfaces, perforating a through-hole that penetrates through one side and the other side of the circuit board, forming a metal film over the heat release layer exposed at an inner wall surface of the through-hole, and forming a plating layer by depositing a conductive metal over an inner wall of the through-hole. By having the heat release layer selectively inserted inside the circuit board, the heat releasing effect may be improved, and the bending strength may be increased. Moreover, a reliable electrical connection can be implemented between the heat release layer and the circuit pattern, making it possible to utilize the heat release layer as a power supply layer or a ground layer.

摘要： Disclosed is a method for optimizing hard handoffs, e.g., between Mobile Switching Centers in a CDMA network. In the method, preliminary conditions for a hard handoff test are first set up. Idle handoffs are then performed in a hard handoff area, log data for the idle handoffs is analyzed and adjustments to communication equipment are made accordingly. Next, hard handoff tests are conducted in a traffic state in the hard handoff area. Log data of the hard handoff tests are analyzed and further adjustments to communication equipment are made if hard handoff performance during the hard handoff tests is determined to be unsatisfactory. A final hard handoff confirmation test is then performed in the hard handoff area following the latter communication equipment adjustments.

摘要： A Radio Network Controller (RNC) in a high speed wireless communication system includes an apparatus to perform method for changing a serving cell in the high speed wireless communication system. The RNC receives UpLink (UL) cell change determination information representing UL channel states from a serving Base Station (BS) and a target BS. The UL is received if a UL soft handover of a Mobile Station (MS) is initiated depending on a DownLink (DL) channel quality of the MS. The RNC can determine UL cell change timing of the MS using the UL cell change determination information. Thereafter, the RNC can send an instruction of a UL cell change of the MS to the serving BS and the target BS.

摘要： A method for controlling forward power utilizing 13K erasure indicator bit in a CDMA system improves the call quality and subscriber capacity by setting a nominal_gain, a maximum traffic channel gain (max_tx_gain), a minimum traffic channel gain (min_tx_gain), and a reduction rate in an optimal combination, wherein the nominal_gain is initial gain of primary traffic channel, the max_tx_gain is maximum gain of traffic channel, the min_tx_gain is minimum gain of traffic channel, and the reduction rate represents a cycle rate to decrease the digital gain by 1 for the received frames. The nominal_gain satisfies E b N o = E c I o + P . G + 10 ⁢ ⁢ log ⁡ [ ( G T ) 2 ( G P ) 2 ] , where E b N o is signal strength of traffic channel, E c I o is pilot signal strength, P.G is power gain, GP is pilot signal gain, and GT is traffic signal gain, and the nominal_gain is adjusted so that a mobile station can have signal strength of traffic channel as 5 dB or more on condition that the pilot signal strength is −14 dB.
