Embodiment Construction

[0035] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0036] The core idea of ​​the present invention is to send appropriate uplink IP packets to the network side preferentially through certain IP packet scheduling rules, so as to reduce the waiting time of the application program on the network side and speed up the speed of sending downlink data from the network side to the UE, thereby fully The purpose of using the data transmission capability (utilization rate) of the air interface. In order to achieve the above object, a kind of data transmission method based on TDD system provided by the present invention mainly comprises the following steps:

[0037] Step 1, setting control parameters for analyzing and processing IP packets.

[0038] An external interface is provided in the UE, through which the user can set control parameters for analyzing and processing IP pac...

Abstract

The invention discloses a data transmission method based on time division duplex (TDD) standard, comprising the steps of setting control parameters which are used for analyzing and processing an IP packet, receiving the IP packet from an IP layer, storing the IP packet in a reception buffer area according to the control parameters, scanning the IP packet in the reception buffer area, analyzing the packet head information of the IP packet, adjusting the sending sequence of the IP packet according to the control parameters, sending the IP packet to a sending buffer area according to the sending sequence, and sending the IP packet in the sending buffer area to a packet data convergence protocol (PDCP) entity according to the sending sequence. The invention further discloses a data transmission method of the TDD standard. The device and the method in the invention improve the utilization rate of idle ports, improve the speed of obtaining data from the network by a user, save user time, synchronously improve network capacity, do not need hardware and reduce operating cost.

Description

technical field [0001] The invention relates to data transmission technology in mobile communication, in particular to a data transmission method and device based on Time Division Duplex (TDD) system. Background technique [0002] In the mobile communication system, if the physical layer is Time Division Duplexing (TDD, Time Division Duplexing) system, then the uplink and downlink communications between the base station and the mobile station use different time slots of the same frequency channel (ie carrier), separated by time Receive and transmit channels, that is, the base station sends signals to the mobile station during a certain period of time, and the mobile station sends signals to the base station at other times. [0003] With the successful commercialization of Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) technology and the trial commercialization of Time Division Duplex Long Term Evolu...
