Problems solved by technology

Considering that in extreme cases, the transmission quality is very poor, the bit error rate (Bite-Error-Rate, BER) and the block error rate are very high, and normal calls cannot be guaranteed. If the wireless connection is still maintained, then it is a problem for wireless resources. wasteful and therefore degrades system performance

Embodiment Construction

[0024] In order to better illustrate specific embodiments of the present invention, below in conjunction with accompanying drawing, further detail as follows:

[0025] Figure 1 is a measurement control flow chart between the base station controller and the base station, as shown in Figure 1, including:

[0026] Step 101, the base station controller sends a measurement request message to the base station, requiring the base station to measure the transmission quality of the uplink, which is specifically expressed as measuring the bit error rate BER of the physical channel;

[0027] Step 102, the base station performs measurement according to the requirements, and reports the result to the base station controller when the reporting requirements are met;

[0028] Step 103, enter the uplink outer loop power control decision process.

[0029] Fig. 2 is a flow chart of uplink outer loop power control decision-making, corresponding to step 103 in Fig. 1, as shown in the figure, incl...

Abstract

The invention relates to a method for improving the service transmission quality of mobile communication system. Wherein, it comprises that the base station real-time compares the tested value of ascending chain quality with target quality value, if the tested value is lower, boosting the target signal / noise ratio; if the boosted target signal / noise ratio is over allowed maximum value, reducing the transmission speed of ascending chain; if present service has the demand to hold bit speed, comparing if the one-step reduced transmission speed of ascending chain is higher than hold bit speed, if it is, reducing one step, or else, releasing wireless connection; if there is no said demand, reducing one step, if present speed is the lowest step, releasing wireless connection.

Description

technical field [0001] The invention relates to a method for improving system performance in the third generation mobile communication system, in particular to a method for improving service transmission quality of the mobile communication system. Background technique [0002] In the 3G CDMA (Code Devision Multiple Address) system, the mobile stations work on the same frequency, and the base stations only rely on the spreading codes of the mobile stations to distinguish them. For the mobile station at the edge of the cell and at the center of the cell, the path losses of the two are different. If two mobile stations transmit with the same power, the signal interference of the mobile station farther from the base station is relatively small, resulting in a large bit error, thus forming a near-far effect. On the other hand, the wireless channel of mobile communication has a wideband dynamic frequency band. These characteristics are related to the nature of mobile users, and a...
