Embodiment 1

[0028] In order to solve the problems that the traditional transmission congestion control method has too much service delay, easily affects voice quality, and increases invalid transmission bandwidth and air interface resource consumption, this embodiment provides a packet loss processing method, which is mainly used in wireless network elements. Please see figure 1 , mainly including the following processes:

[0029] S101, the first wireless network element detects the received data packet according to the preset detection rules, and obtains the detection result, whether the detection result is a data packet loss, if so, proceed to step S102, if not, return to step S101 to continue detection .

[0030] Different detection rules may have different detection results. Therefore, when the detection result of this step is packet loss, it does not mean that packet loss actually occurred. It is only detected according to this detection rule, and a certain type of detection result ...

Embodiment 2

[0043] Taking the 3G network as an example, the wireless RAN side of the 3G network is divided into two wireless network elements, the controller and the base station. The network adopts the traditional transmission congestion control method, the service delay is too large, it is easy to affect the voice quality, and increase the invalid transmission bandwidth and air interface resource consumption. This embodiment provides the following packet loss processing methods, please refer to figure 2 , mainly including the following processes:

[0044] S201. The controller sets a frame number for an FP (Frame Protocol) frame of a data service data packet as a sending number: 0 to 255 frame numbers.

[0045] S202. The controller sends the FP frame data packet carrying the FP frame serial number to the base station.

[0046] S203, the base station sets the waiting time T of the timer according to the RTT delay of the IUB interface (the logical interface between the controller and the...

Embodiment 3

[0055] For data services, RLC (Radio Link Control, radio link layer control protocol) SN (Sequence Number, sequence number) can also be used as the sending sequence number of data packets. Taking 3G network as an example, in order to solve the problem of traditional transmission congestion control in 3G network Method The service delay is too large, it is easy to affect the voice quality, and increase the invalid transmission bandwidth and air interface resource consumption. This embodiment provides another packet loss processing method. Please refer to image 3 , mainly including the following processes:

[0056] S301. The controller sends a data service data packet to the base station, and the data packet carries an RLC SN.

[0057] S302. The base station sets the waiting time T of the timer according to the RTT delay of the IUB interface (the logical interface between the controller and the base station).

[0058] S303, the base station detects whether the RLC SNs of the r...

Abstract

The embodiment of the invention provides a packet loss processing method and device, wireless network elements and a computer readable storage medium. The method comprises the following steps: detecting a received data packet by a first wireless network element according to a preset detection rule; if the detection result is that the data packet is lost, feeding back loss information to a second wireless network element for sending the data packet, wherein the loss information is used for indicating the lost data packet. The data packet loss detection and retransmission are accomplished between wireless network elements through the method provided by the embodiment of the invention; and compared with the way of performing packet loss detection by a terminal and performing retransmission between the wireless network element and the terminal in the prior art, the packet loss processing method has the following advantages: 1) the service delay is reduced, and a transmission rate is improved; 2) for a voice service, the condition that the voice quality and the voice MOS value are influenced due to serious congestion of a transmission link between the wireless network element and the terminal can be avoided; and 3) the terminal does not need to send a NACK message to import retransmission, and the wireless network element does not need to perform air interface retransmission on theterminal, and the transmission bandwidth occupancy and the air interface resource consumption can be avoided.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a packet loss processing method, device, wireless network element and computer-readable storage medium. Background technique [0002] With the rapid development and deployment of wireless networks, as well as the rapid growth of user groups, the traffic of network transmission data increases rapidly, which puts great pressure on the operation of the existing network. [0003] The rapid increase in data traffic requires higher and higher transmission bandwidth between wireless network elements. Moreover, operators often deploy a transmission network to support all existing network operating equipment, and the transmission bandwidth between wireless network elements is often all Device sharing not only requires the sharing of transmission resources for single-device single-mode wireless networks, single-vendor multi-device multi-standard wireless networks, but also need...
