AI Technical Summary

Benefits of technology

This technology allows for efficient communication by allowing packets from different base stations without having their own headers attached or being copied onto other devices connected through an access point called Evolved Node B(eNB). By setting up certain specific parameters within this signal, it becomes possible to transmit data over multiple paths simultaneously with minimal overhead. Additionally, because these signals are transmitted wirelessly instead of carrying them separately, they can also improve upon existing networks' capabilities while reducing its impact on processing resources. Overall, this innovation improves efficiency and performance in wireless communications systems like Long Term Evolution (LTE), which requires more complex protocol processes than traditional wired connections due to increased complexity.

Problems solved by technology

Technical Problem addressed in this patented technology describes how different types of connections may occur during operation when transmitting data over both Wideband Code Division Multiple Access (WiMAX) networks and Time Division Multiplex Connection Overall, there exist challenges related to efficient handling of large amounts of data traffic across these two modes of connectivity.

Embodiment Construction

[0030] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0031] The downlink data packets received by the target eNodeB include data packets forwarded by the source eNodeB and data packets delivered by the target SGW. The data packets forwarded by the source eNodeB include data packets processed by PDCP and data packets not processed by PDCP. Among the data packets forwarded by the source eNodeB, the PDCP-processed data packets carry the PDCP SN. Packets that have not been processed by PDCP do not carry a PDCP SN. Let the data packets processed by PDCP in the source eNodeB be the first type of data packets.

Abstract

The invention relates to a downlink data packet transmitting method, a system and an evolution base station. In the embodiment of the downlink data packet transmitting method, a downlink data packet comprises a data packet transmitted by a source evolution base station eNodeB, and among the data packets transmitted by the source eNodeB, the data packet processed by the source eNodeB by a packet data convergence protocol (PDCP) is set as the data packet of first class, comprising the following steps: the source eNodeB sets the PDCP SN in the message head of the data packet of first class; and the source eNodeB transmits the data packet of first class to a target eNodeB. By setting the PDCP SN in the message head of the data packet, the embodiment of the invention leads the data packet message to carry the PDCP SN when being switched between the eNodeBs (namely the switching on an X2 interface) without using the mode of expanding the head, thus reducing the processing load of network nodes and eNodeB nodes in an LTE network, and enhancing the processing capacity and performance of the whole network.
