Embodiment Construction

[0033] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0034] 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:

[0035] Step 1, setting control parameters for analyzing and processing IP packets.

[0036] 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 of a time division duplex (TDD) system, comprising: setting control parameters for analyzing and processing IP packets; receiving IP packets from the IP layer, and storing the IP packets in the receiving Buffer; scan the IP packet in the receiving buffer, analyze the packet header information of the IP packet, and adjust the sending sequence of the IP packet according to the control parameters, send the IP packet into the sending buffer according to the sending sequence; send the IP packet into the sending buffer according to the sending sequence The IP packets are sent to the Packet Data Convergence Protocol (PDCP) entity. The invention also discloses a data transmission method of the TDD system. Through the device and method of the present invention, the utilization rate of the air interface is improved, the speed for users to obtain data from the network side is improved, and user time is saved; at the same time, the network capacity is also improved without hardware investment, which also reduces operating costs.

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...
