Problems solved by technology

[0006] However, while the system architecture meets the data rate requirements of the UE, it cannot take into account the stability of the mobility performance of the UE. When the SeNB cell accessed by the UE changes, the data interruption time and data loss caused by the change of the SeNB serving cell cannot be reduced. package, unable to reduce the impact on the network side and terminal nodes caused by SeNB cell changes

Abstract

Disclosed are a data package shunting transmission method and system, and a computer storage medium. The method comprises: converting an RLC SDU data stream sent by a PDCP layer into a first RLC PDU data stream and a second RLC PDU data stream through an M-RLC layer; sending the first RLC PDU data stream to a first MAC layer, sending the second RLC PDU data stream to an S-RLC layer, performing partitioning and / or cascade treatment on and adding / modifying PDU package heads of the various RLC PDUs in the second RLC PDU data stream through the S-RLC layer, and sending same to a second MAC layer; and respectively sending the first RLC PDU data stream and the second RLC PDU data stream to a receiving end by means of the first MAC layer and the second MAC layer. Also disclosed at the same time is a data package shunting transmission system. By adopting the present invention, the service requirements of high mobility of a UE can be taken into consideration while meeting the large data volume requirements of the UE.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and system for splitting and transmitting data packets. Background technique [0002] With the continuous evolution of wireless communication technology and protocol standards, the mobile packet service has undergone tremendous development, and the data throughput capability of a single terminal has been continuously improved. Taking the Long Term Evolution (LTE, Long Term Evolution) system as an example, it can support data transmission with a maximum downlink rate of 100 Mbps within a 20M bandwidth; in the subsequent enhanced LTE (LTE-A, LTE-Advanced) system, the data transmission rate will be Further improvement, it can even reach 1Gbps. [0003] The expansive growth of terminal data traffic has brought enormous pressure and challenges to mobile network service capabilities and deployment strategies. On the one hand, operators need to enhance existing netwo...
