Problems solved by technology

[0005] The disadvantage of this fixed configuration BLERTarget control method is: once the BLERTarget of a certain service in WCDMA is set, the QoS of this kind of service is also determined and remains unchanged during operation
Therefore, this control method of fixedly configuring BLERTarget cannot fully, rationally and effectively utilize cell resources, such as power resources

Embodiment Construction

[0028] The core idea of ​​the present invention is: aiming at the technical problems existing in the control strategy of fixed BLERTarget configuration for existing services, the BLERTargets of various services can be dynamically adjusted according to the load conditions of the cells. Especially when the number of users in the cell is relatively small, or when the load of the cell is low, such as during off-peak hours, by reducing the BLERTarget, the data transmission rate of the data service or the voice quality of the voice service can be improved, so that the corresponding QoS can be improved, and it can be more Reasonable use of cell resources, such as power resources. When the load rate of the cell is greater than the set threshold value, increasing the BLERTarget can ensure that the cell provides services for new users.

[0029] In order to have a further understanding of the present invention, the method described in the present invention will be described in detail bel...

Abstract

The invention relates to the dynamic controlling method of the error block rate target value in the WCDMA system, the error block rate target value of all sorts of the operation or the users can be adjusted by the loading instance of the little section. When the loading of the little section is on the small side, the corresponding error block rate target value is depressed, the data transmitting speed rate or the tone quality of the tone operation can be improved, in the other word, the serving quality of some kind of the operation or the user can be improved, so the little resource can be used fully; when the little loading is bigger, the corresponding error block target value is improved, the little section can supplies the serve to the new user. So, compared to the controlling method of the fixing collocate error block target value, the invention can adjust the error block rate target value at and moment according to the needing, the little section source can be used fully, so the serving quality to the user can be improved.

Description

technical field [0001] The invention relates to the technical field of wireless network communication, in particular to a dynamic control method of a block error rate target value in a WCDMA system. Background technique [0002] In the WCDMA system, the outer loop power control is to ensure that the communication reaches a certain QoS (quality of service) by adjusting the SIRTarget (target signal-to-interference ratio) of the inner loop power control. If the channel quality is higher than QoS, then reduce SIRTarget, otherwise, increase SIRTarget. In this process, QoS is generally measured by BLERTarget (block error rate target value), the lower the BLERTarget, the higher the QoS. [0003] For certain services in WCDMA, such as circuit switching services or packet switching services, a certain BLERTarget needs to be set. The WCDMA base station controller obtains the SIRTarget according to the BLERTarget and the current BLER (block error rate), and then makes the QoS of the s...
