Problems solved by technology

[0006] Since this method is adjusted for a single user and does not regulate the status of the entire cell, it is possible that the cell is already overloaded, but the users in a local area are still increasing the speed, which further deteriorates the communication quality of the cell and reduces the capacity.
At the same time, since each user is reporting measurement reports, a large amount of transmission resources are occupied, and the processing of each measurement report also takes up a lot of processing time, which has a certain impact on the stability of the system

Embodiment 1

[0030] Uplink overload deceleration process;

[0031] In the RNC, pre-configure the cell uplink overload trigger threshold to be -100dBm, and the uplink overload release threshold to be -101dBm. The NodeB periodically checks the total power of the cell receiving bandwidth and reports it to the network side. When the monitoring finds that its value is -99dBm, which exceeds the uplink overload trigger threshold, the cell is in an overload state, and a cell uplink overload event report is triggered, and the RNC checks all AMR voice users in the cell, assuming that the guaranteed uplink rate of users in this cell is 4.75k , if the current uplink rate of a user is 12.2k, which is greater than the guaranteed rate, an uplink speed reduction process will be initiated. If the number of users meeting the speed-down condition is relatively large, the speed-down processing will be performed in batches according to the preset number of users (for example, 3) processed each time. Continue ...

Embodiment 2

[0034] Downlink overload deceleration process;

[0035] The pre-configured cell downlink overload trigger threshold is 60%, and the downlink overload release threshold is 50%. Periodically check the carrier transmit power of the cell and report it to the network side. When the value is found to be 65%, exceeding the downlink overload trigger threshold, the cell downlink overload event report will be triggered, and the RNC will check all AMR voice users in the cell. Assuming that the user in the cell The guaranteed downlink rate is 4.75k. If the current downlink rate of a user is 12.2k, which is greater than the guaranteed rate, the downlink rate reduction process will be initiated. If the number of users meeting the speed-down condition is relatively large, the speed-down processing will be performed in batches according to the preset number of users processed each time (for example: 3). Continue to check the carrier transmit power of the cell during the process, and find tha...

Abstract

This invention discloses an adjustment method for phonetic rate of radio base station local areas, which first of all measures the load situation of a local area, then judges if the load of the area belongs to underload, normal or overload based on the load information, then reduces the rate of phonetic users of the area at the over load state to reduce the down area emission power and up UE emission power to reduce the load of local areas.

Description

technical field [0001] The invention relates to the adjustment technology of cell voice rate in the wireless communication field, in particular to a method for adjusting the voice rate of a wireless base station cell. Background technique [0002] In a CDMA communication system, multiple cells can use the same carrier frequency for communication at the same time. On the sending side, the signals of each link are modulated with different PN codes. The downlink mobile station) is distinguished by orthogonal codewords. [0003] In a CDMA system, maximization of system capacity is a very important issue. Because the CDMA system is a self-interference system, the transmission power of each mobile station is interference to other mobile stations. Other users are also distracting. Therefore, in order to ensure the communication quality of all users, the total power in the cell, that is, the load level, cannot be increased without limit, otherwise the quality of users in the enti...
