Embodiment Construction

[0064] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0065] refer to figure 1 , shows a flow chart of Embodiment 1 of an uplink data transmission method of the present application, the uplink data is sequentially processed by the PDCP sublayer, the RLC sublayer and the MAC sublayer, and the method may specifically include the following steps:

[0066] Step 101. Receive service data to be transmitted.

[0067] This application is mainly applied to the Long Term Evolution (LTE) system. According to LTE system related technical standards (TS36.321, TS36.322, TS36.323), the uplink data plane processing involves PDCP (Packet Data Convergence Protocol, Packet Data Convergence), RLC (Radio Link Control, Radio Link Control), MAC (Medium Access Control, Media Acce...

Abstract

The application provides an uploading data transmission method and an uploading data transmission device. Uploading data are sequentially processed by a PDCP (Packet Data Convergence Protocol) sublayer, an RLC (Radio Link Control) sublayer and an MAC (Media Access Control) sublayer. The uploading data transmission method comprises the following steps of: receiving service data to be transmitted; judging whether the service data conform to preset conditions or not, and transmitting the service data to the PDCP sublayer if the service data conform to the preset conditions, or adding the service data in a cache queue if the service data do not conform to the preset conditions; transmitting an uploading data transmission request to a base station; scheduling the service data processed through the PDCP sublayer and the RLC sublayer by the MAC sublayer according to oncoming distributed resource quantity returned from the base station on the basis of the transmission request; and transmitting the uploading data according to a scheduling result of the MAC sublayer, and triggering the service data in the cache queue to dequeue and enter the PDCP sublayer according to estimated next distributed resource quantity. The uploading data transmission method and the uploading data transmission device can be used for overcoming time delay added on a confirmation pack corresponding to the download of a TCP (Transmission Control Protocol) by virtue of an uplink data transmission mechanism in the conventional LTE (Long Term Evolution) system, thus improving the downloading performance of the TCP.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to a method and device for transmitting uplink data. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) is a standardization organization established in December 1998. The continuous growth of mobile communication services promotes the 3GPP to develop Long Time Evolution (LTE, Long Time Evolution) specifications. [0003] In the LTE system, the mobile communication terminal downloads the corresponding confirmation packet according to the TCP communication protocol. TCP is a connection-oriented, reliable, and byte-stream-based transport layer (Transport layer) communication protocol. The TCP protocol is widely used in various File transfer protocols, such as FTP (File Transfer Protocol), because the LTE system requires mobile communication terminals (UE) to have a data download capability of 100 Mbps...
