Problems solved by technology

[0006] 1. If you do not strictly consider the QoS requirements of the service when configuring Bler, you cannot guarantee whether the configured Bler meets the QoS value of the service
Moreover, there are various intermediate processing links. Different processing methods and parameter configurations in different processing links will require different Bler target values. However, it is impossible to configure the Bler value in all cases according to all processing methods in the system. A typical configuration approximate Bler value
[0007] 2. Once the required Qos changes, the Bler value of the physical layer cannot be dynamically adjusted
[0008] 3. Even if the service type remains unchanged and the required Qos remains unchanged, the existing Bler configuration will not meet the Qos requirements after the processing method or parameters of the intermediate processing link are changed.

Embodiment Construction

[0023] In the WCDMA system, the QoS attributes of the business include many, such as the maximum rate, guaranteed rate, time delay, SDU error rate and so on. In the present invention, the emphasis is on considering the influence of the SDU error rate factor on the physical layer. Since the SDU imported from the non-access layer needs to go through multiple links to the TB (Transport Block) of the underlying physical layer, the processing aspects and parameter configurations of different links will more or less affect the Bler configuration.

[0024] The QoS of the service refers to the quality requirements of the SDUs imported by the non-access layer, and the Bler refers to the physical TB blocks. SDU is converted into TB. For example, the following behavior needs to be processed by RLC layer and MAC layer of L2 (Radio Network Control, Layer 2) of RNC to become TB. The transmission block is transmitted through the air interface, and the wireless channel transmission will gene...

Abstract

The invention relates to a method to configure error block rate according to business service quality in wireless communication field, which comprises: (1) after receiving wireless carries configuration information of non-access layer, the access layer acquires SDU error rate and size according to contained Qos attribution; (2) RLC configures opposite parameters and transmission mode according to said information; (3) determining error block rate of opposite physical layer by the RLC transmission mode and SDU error rate and SDU size.

Description

technical field [0001] The invention relates to the parameter configuration of the physical layer in the WCDMA system, especially a method for configuring the block error rate of the physical layer according to the quality of service (Qos). Background technique [0002] At present, in the access layer of the WCDMA system, how to configure the Bler (Block error ratio, block error rate) of the physical link according to the Qos (Quality of service, service quality) required by the business has not been a very reasonable method. The main reason is that there is no strict correspondence between the configuration of the block error rate of the physical link and the QoS performance index of the service. In the process of transmitting service data packets from the Iu port (the standard interface between the radio network controller and the core network) to the physical layer, it needs to go through RLC (Radio Link Control, radio link control), MAC (Medium Access Control, media acc...
