Abstract

The invention discloses a service data preprocessing method and system. The method comprises the following steps: updating, by a sequence processing unit (SPU), capability configuration information ofcurrently stored corresponding carriers according to an updated scheduling capability indication reported by a radio access unit RAU in real time; within each scheduling period, according to the principle of preferentially processing low-delay service data in a local cache, generating RLC PDU by using the data in the local cache and according to the capability configuration information of the currently stored corresponding carriers, and placing the RLC PDU in a corresponding low-delay service data queue or an ordinary service data queue; for the low-delay service data queue, sending the RLC PDU to the corresponding RAU by using a preset low-delay sending mode; and for the ordinary service data queue, sending the RLC PDU to the corresponding RAU by using a preset ordinary sending mode. Byadoption of the service data preprocessing method and system disclosed by the invention, the coupling correlation between the RLC and an MAC protocol layer can be greatly reduced, so that the SPU andthe RAU can be deployed independently.

Description

technical field

[0001] The invention relates to mobile communication technology, in particular to a service data preprocessing method and system. Background technique

[0002] With the performance of LTE-A to 5G, the transmission rate of the cell has increased by dozens of times, exceeding 10Gbps. On the other hand, the LTE network follows the principle of a flat structure, and the media access control (MAC) layer cancels the segmentation function, that is, cancels the SI control domain in the TDS era, and has no ability to concatenate message segments. The radio link control (RLC) layer is moved down from the radio network controller (RNC) to the evolved Node B (eNB), and needs to undertake the segment concatenation function according to the MAC scheduling situation.

[0003] In the above solution, since RLC needs to dynamically output RLC PDUs with precise length to the MAC layer in this scheduling cycle according to the real-time scheduling situation of MAC, the data tra...

Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0028] The core idea of ​​the present invention is: in each scheduling period, according to the scheduling situation, the data in the cache is generated in advance into an RLC PDU and sent to the MAC layer. In this way, by pre-packaging the data before the data is scheduled, the RLC layer will no longer generate time overhead due to the generation of the data packet during scheduling, thereby increasing the tolerable transmission time between the RLC and MAC protocol layers. The delay can greatly reduce the coupling association between the RLC and the MAC protocol layer, and enable flexible independent (distributed) deployment of the SPU and the RAU.
