Embodiment Construction

[0104] In the embodiment of the present invention, after the terminal has uplink data to be sent, it determines the uplink transmission resource through the air interface random access method; sends the uplink data and the target address pre-allocated by the network side to the base station through the uplink transmission resource, so that the base station can transmit the uplink data according to the target address. The address sends the uplink data to the corresponding gateway, so that the transmission of burst small data packets can avoid the control plane delay and air interface signaling burden caused by the transition from the idle state to the connected state after the data arrives; it can also reduce the terminal's access to the connection After the state, the connection maintenance overhead introduced due to no data transmission for a long time improves the performance of the existing cellular system in terms of uplink burst small data transmission.

Abstract

An embodiment of the invention relates to the technical field of wireless communication, and particularly to a method and equipment for transmitting uplink data. The method and the equipment are used for settling problems of introducing high signaling load and waiting delay and increasing processing time delay of a base station on condition of emergent small data packet transmission based on a data transmission solution with connection in prior art. The method provided by the invention comprises the steps of determining uplink transmission resource in an idle random accessing manner after uplink data transmission is required; transmitting the uplink data and an objective address which is pre-allocated by the network side to the base station through an uplink transmission resource so that the base station transmits the uplink data to a corresponding gateway according to the objective address, thereby preventing control surface time delay and idle interface signaling load which are introduced in conversion from an idle state to a connecting state after data arrival when emergent small data packet transmission occurs.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and equipment for transmitting uplink data. Background technique [0002] In the current LTE (Long Term Evolution, Long Term Evolution) cellular system, the RRC (Radio Resource Control, Radio Resource Control) connection will be released when the terminal has no data transmission for a long time, so after the subsequent uplink data arrives, the terminal first needs to restore the RRC signaling Only when the user plane is connected can the user plane data transmission be carried out. Currently, it takes at least 80ms to restore the control plane connection process. [0003] The existing LTE uplink fast transmission scheme requires the terminal to initiate an access process to the serving base station and obtain an index ID (identification) before performing uplink data transmission. The base station associates the index ID with the terminal (UE) con...
