Problems solved by technology

[0006] But the current status quo is: a transmission network carries products of different manufacturers and standards, and even non-wireless devices. First, not all manufacturers’ devices have the congestion control function. The start-up strategy, control pace, and control goals of transmission congestion control for each standard of each manufacturer are also different. In actual operation, even the transmission bandwidth or processing capacity confiscated by a certain site is immediately seized by other devices; the overall control is difficult to work, resulting in the current The phenomenon is: the number of packets on the transmission network exceeds the processing capacity or the traffic exceeds the receiving buffer or sending buffer capacity of each node in the intermediate transmission, resulting in high priority packets also showing high loss rate and long delay. The business is affected, especially the failure to make calls during working hours often causes a large number of complaints or loss of customers

[0076] like Figure 4 As shown, the second embodiment of the present invention proposes a data transmission method. Based on the first embodiment above, the method further includes:

[0077] Step S103, when the service message transmission performance parameter in the current detection period is reduced to not meet the preset condition, control the base station and the controller to stop discarding some preset low-priority service messages and stop the preset high-priority Multiple intervals of sending service packets.

[0078] The above step S102 is S1021, when the service message transmission performance parameter in the current detection period reaches the preset condition, control the base station and the controller to discard some preset low priority service messages according to the preset ratio to reduce IUB interface transmission flow, and controlling the base station and the controller to send preset high-priority service messages at multiple intervals on the IUB int...

Embodiment 1

[0085] For a South American operator, one transmission network supports all 3G and 4G equipment, and the wireless equipment comes from three manufacturers. Because a certain type of transmission and aggregation equipment is old and the packet switching capability is limited, it can no longer meet the needs of the existing network, but in the short term It is still not possible to replace the whole network of the equipment. From the monitoring of the transmission network of the single-vendor equipment, it is obvious that the indicators are good at night and poor during the day. Delay and jitter are unstable, tens to hundreds of milliseconds, making it difficult to make calls during the day, and the observed RRC connection success rate is also very low, only between 30 and 40%.

[0086] After the single-vendor equipment adopts transmission congestion control, it periodically checks the transmission quality, and actively discards some low-priority packets during periods of high lo...

Embodiment 2

[0095] A domestic operator, with a transmission network, first opened a 3G network, and then introduced several manufacturers to the original transmission network as the 4G network began to be constructed. The network gradually detects that the bandwidth of some ports is insufficient. Due to the characteristics of the mobile network, the ports with insufficient bandwidth are not fixed and only appear in a few time periods, but the time period is not fixed. The expansion of the entire transmission network has yet to be designed and planned. When the transmission quality is relatively poor, the loss rate is also close to 10%, and the number of user complaints begins to rise.

[0096] In this scenario, select a site that has experienced transmission degradation to implement the solution used in the present invention, and the process is as follows:

[0097] Step 1, NodeB and RNC detect the transmission quality of the IUB interface in a 5-minute cycle, and count the transmission lo...

Abstract

The invention discloses a data transmission method, a device thereof and a storage medium. The data transmission method comprises the steps of periodically detecting IUB interface transmission qualitybetween a base station and a controller, and performing statistics of a service message transmission performance parameter according to the IUB interface transmission quality; and when the service message transmission performance parameter in a current detecting period satisfies a preset condition, controlling the base station and the controller to transmit or abandon the service message according to a preset priority and a preset rule. According to a counter-IUB interface adverse transmission solution, on the present condition of high loss rate and high time delay in current partial operators, the loss rate of important messages of the IUB interface can be reduced without time delay increase, thereby improving service performance, reducing call drop rate and call completion ration, and improving service quality and user satisfaction.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a data transmission method, device and storage medium. Background technique [0002] With the rapid development and deployment of wireless systems, a large number of 3G base stations and 4G base stations are deployed in the existing network, and the user group grows rapidly, and a large number of people who bow their heads and mobile phones are born, followed by the rapid growth of data traffic in mobile communication networks. The increase will put great pressure on the operation of the existing network. On the one hand, it will put a lot of pressure on the deployment density and processing capacity of 3G, 4G and other standard base stations. pressure. [0003] The rapid increase of data traffic has higher and higher requirements for the transmission bandwidth between the base station and the core computer room. Moreover, operators often use a transmission network...
