Problems solved by technology

However, downlink scheduling can only be carried out for the bearer level, and it is impossible to provide refined service quality (QoS, Quality of Service) guarantee for the services contained in the bearer.
At this time, the interactive services in the mixed service, such as web browsing, are often blocked by services such as BitTorrent (BT, BitTorrent) download, which seriously affects the user experience of interactive services.
In addition, due to the flow control mechanism of the Transmission Control Protocol / Internet Protocol (TCP / IP, Transmission Control Protocol / Internet Protocol), when the user transmits data up and down at the same time, if the downlink rate is limited, the uplink rate will eventually be pulled down.
[0003] Since LTE is an emerging technology, there is no solution to the above problems in the current public information

Embodiment Construction

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0015] In the LTE base station according to the embodiment of the present invention, the PDCP entity of the LTE base station sets at least one priority buffer queue for buffering downlink data of at least one service transmitted through one bearer. When the PDCP entity sends data to the RLC entity upon request, the PDCP entity reads data from each buffer queue and sends the data to the RLC entity according to the priority of the buffer queues. I...

Abstract

A Long Term Evolution (LTE) base station equipment and a method for processing data service in the LTE base station equipment are provided in the present invention embodiment. The method for processing the data service in the LTE base station of the present invention embodiment includes that: at least one cache queue is set in the Packet Data Convergence Protocol (PDCP) entity of the LTE base station for caching the downlink data of at least one data service transmitted by one bearer, and each cache queue has respective priority; after said bearer is established, when PDCP entity transmits data to a Radio Link Control (RLC) entity in the LTE base station by request, the PDCP entity transmits the data in each cache queue to the RLC entity according to the priority of at least one cache queue. According to the embodiment of the present invention, the differentiation of the service Quality of Service (QoS) can be realized in the LTE base station.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication, and in particular to a long term evolution (LTE, Long Term Evolution) base station and a method for processing data services thereof. Background technique [0002] In an LTE mobile communication system, when a user simultaneously performs multiple data services such as web page browsing and BitTorrent (BT, BitTorrent) download, these services are usually transmitted in a certain bearer. However, the downlink scheduling can only be performed for the bearer level, and it is impossible to perform fine-grained Quality of Service (QoS, Quality of Service) guarantee for the services included in the bearer. At this time, the interactive services in the hybrid service, such as web browsing, are often blocked by services such as BitTorrent (BT, BitTorrent) download, which seriously affects the user experience of the interactive services. In addition, due to the flow control mec...
