Problems solved by technology

[0035] AN sends RLP packets with SAR_Seq numbers 1, 2, 3, 4, 10, 11, 13, and 15 in carrier link 1, and at the same time, sends SAR_Seq numbers 5, 6, 7, 8, The RLP packets of 9, 12, 14, and 16 are set to be deleted suddenly after carrier link 1 sends the data frame due to some reasons such as signal deterioration. At this time, carrier link 1 In this way, all RLP packets with SAR_Seq numbers 10, 11, 13, and 15 are lost. However, according to the current data frame retransmission mechanism, AT cannot detect frame errors, so AT cannot trigger in time NAK message, to request AN to resend RLP packets with SAR_Seq sequence numbers 10, 11, 13 and 15, will have a very large impact on AT receiving data frames, seriously affecting the reliability of data frame transmission
[0036] To sum up, the current data frame transmission method in some application scenarios, the AT cannot detect the wrong frame, and the AN cannot send the lost data frame to the AT, so that the transmission reliability of the data frame is poor, and the data frame is retransmitted. The mechanism needs to be further improved

Embodiment Construction

[0060] The core of the method of the present invention is: when the forward carrier link of the wireless access terminal needs to be deleted, the wireless access terminal transmits the data frame information received from the forward carrier link to the wireless access network, and the wireless access The network transmits the corresponding data frame to the wireless access terminal according to the data frame information transmitted by the wireless access terminal.

[0061] The technical solution provided by the present invention will be further described below based on the core idea of ​​the present invention.

[0062] When the AT needs to be handed over or the signal deteriorates, etc., its forward carrier link needs to be deleted. When the AT of the present invention needs to delete its forward carrier link, it needs to use the information received in the forward carrier link. Data frame information is transmitted to AN. There can be one or more forward carrier links that...

Abstract

This invention provides one data frame transmission method and system based on non-answering mechanism, which comprises the following steps: when wireless interface terminal front end load circuit needs deletion, the terminal sends the received data frame information into network from front load wave linkage; the wireless interface network sends the data frame information into interface terminal. This invention can send the error frame tested by wireless interface terminal into wireless interface terminal on data losing situation.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data frame transmission method and system based on a non-response mechanism. Background technique [0002] At present, 3G mobile communication technology is gradually mature and commercially available. 3GPP2 (Third Generation Mobile Communication Cooperation Project Organization 2) CDMA2000 1XEV-DO (Evolution, Evolution, Data Only, only supports packet data services) will further provide competitive services in the next few years. wireless access system. [0003] 1XEV-DO technology is a technology used to transmit high-speed packet data services. The maximum peak rate supported by each sector carrier frequency can reach 2.4Mbps. In version A, the peak rate can reach 3.1Mbps. However, in order to maintain competitiveness in the next decade or decades, it is necessary to introduce new wireless access technologies. [0004] At present, the industry has reached a pr...
