Problems solved by technology

[0005] Because the existing terminal is in a hierarchical working state, when the user communicates using the QUIC protocol, when the uplink communication rate of the terminal is limited, there may be a large number of ACK only packets queued and transmitted sequentially in the data link layer buffer At this time, because the ACK only packet carries the ACK information used to trigger the base station to send downlink data, the uplink transmission rate is limited so that the base station delays receiving the ACK information, which in turn causes the downlink data to be delayed, and finally leads to the downlink transmission rate of the base station. reduce

Embodiment Construction

[0037] The present application provides a data processing method and terminal, which are used to reduce the amount of uplink transmission data and increase the uplink transmission speed when the uplink transmission rate of the terminal is limited, thereby improving the downlink transmission rate and network coverage.

[0038] The technical solutions in the present application will be clearly and completely described below with reference to the accompanying drawings in the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0039] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It is to be understood that data so used may be interchanged under appropriate circumstances so...

Abstract

The application provides a data processing method and terminal. When the uplink transmission rate of the terminal is limited, the uplink transmission data size is reduced, and the uplink transmissionspeed is improved, thereby improving the downlink sending rate and the network coverage rate. The method provided by the application comprises the following steps: the terminal judges whether a QUIC data packet is an ACK only packet according to the packet length of the QUIC data packet when the QUIC data packet is sent to a data link layer of the terminal; the terminal records a cache address forstoring the QUIC data packet in a cache region if the QUIC data packet is the ACK only packet; and the terminal determines the un-encapsulated ACK only packet in the data link layer and deletes the un-encapsulated ACK only packet from the cache region when a new ACK only packet arrives the data link layer.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a data processing method and terminal. Background technique [0002] Quick UDP internet connections (QUIC) is a multiplexing and secure transmission protocol based on the user datagram protocol (UDP) and incorporating the advantages of many protocols. The QUIC protocol has the advantages of low control overhead and rapid connection establishment, and solves the problem of head-to-head blocking and ensures the continuity of network switching, which is the development trend of wireless networks. [0003] QUIC data packets mainly include public headers, acknowledgment information ACK frames, stop-wait frames and stream frames. Among them, the public header carries information such as the sequence number of the QUIC data packet, the ACK frame is used to confirm the received data to the peer device, and the stop-wait frame is used to inform the peer device tha...
