Method for transmitting data between terminal and network and system, network and terminal

Abstract

The inventive embodiment discloses a method for data transmission between a terminal and a network, including: when creating a data transmission channel, emitting a switch command from the network to the terminal, the said terminal transmitting data with a data transmission channel assigned to a target subdistrict by the switch command. When the switch command includes newly-create data transmission information not contained in the terminal, the terminal also creates new data transmission channel corresponding to the target subdistrict before transmitting data. Further, the inventive embodiment discloses a system, network and terminal for data transmission between a terminal and a network. The invention improves success rate of user data transmission, and maximally meets the requirement of a user for data transmission.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless communication, and in particular, to a method, system, network, and terminal for transmitting data between a terminal and a network. Background technique [0002] Temporary Block Flow (TBF, Temporary Block Flow) in wireless communication technology is a communication transmission channel used to support uplink (data flow from mobile unit to mobile communication system) and downlink (data flow from mobile communication system to mobile unit), It is a physical connection used between two radio resource (RR, Radio Resource) entities to support unidirectional upper layer protocol data unit (PDU, Protocol Data Unit) transmission on a packet data physical channel (PDPCH, Packet Data Physical Channel) . [0003] See figure 1 As shown in , it is a flowchart of a method for uplink data transmission in the prior art. In the prior art, the process for the terminal to send uplink ser...

AI Technical Summary

Problems solved by technology

[0006] During the creation process of the present invention, the inventor found at least the following problems in the prior art: when establishing a data transmission channel in the prior art, the terminal can only perform data transmission in the current cell, if the current cell does not have enough resources to meet the required When the above data transmission requirements are met, the network can only cancel the transmission of this group of data

This will affect the transmission of a large amount of business data, so that the business data transmission needs of users cannot be met to the maximum extent, and the efficiency of data transmission in the network is reduced.
