Problems solved by technology
However, downlink scheduling can only be performed 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 a 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. In this way,...

Embodiments of the present invention provide LTE base station equipment and a method for processing data services in the LTE base station equipment. The method for processing data services in an LTE base station according to an embodiment of the present invention includes: setting buffer queues in the PDCP entity of the LTE base station to buffer downlink data of at least one data service to be transmitted via a bearer, and each buffer queue has its own After the bearer is established, when the PDCP entity requests to send data to the RLC entity in the LTE base station, the PDCP entity sends the data in each buffer queue to the RLC entity according to the priority of the buffer queue. According to the embodiment of the present invention, service QoS differentiation 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, downlink scheduling can only be performed for the bearer level, and it is impossible to provide refined 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 mechanism of...
