Description

Data transmission method, device and storage medium

technical field

The present invention relates to the field of communication technologies, and in particular, to a data transmission method, device and storage medium.

Background technique

With the rapid development and deployment of wireless systems, a large number of 3G base stations and 4G base stations have been deployed in the existing network, and the user group has grown rapidly, resulting in the birth of a large number of bow-heads and mobile phones, followed by the rapid growth of data traffic in mobile communication networks. On the one hand, it puts a lot of pressure on the deployment density and processing capacity of 3G, 4G and other standard base stations; pressure.

The rapid increase in data traffic requires higher and higher transmission bandwidth between the base station and the core computer room. Moreover, the operator is often a transmission network that supports all existing network operating equipment, that is, the transmission from the site to the core computer room. Bandwidth is often shared by all devices. Not only do wireless systems with multiple standards from a single manufacturer need to share transmission resources, but there are also shared transmission resource requirements between multiple manufacturers, and even bandwidth sharing requirements for other non-wireless devices. The characteristics of high bandwidth and high mobility of 3G and 4G equipment, and the flow and peak value change with the characteristics of the flow of people, posing great challenges to operators' transmission design, traffic forecasting and fine management.

In the actual network inspection and operation, it is found that there are some communication system managers, or it is difficult to meet the requirements of transmission network design, traffic prediction and fine management, or the design of transmission network, the construction is difficult to synchronize with the progress and requirements of wireless equipment expansion In the current network, it is found that the quality of the transmission network between the operator's site and the core computer room is poor, and it is manifested in peak periods. Even high-priority packets still have high loss rates and high delays on the transmission network. As a result, the user's perception decreases, it is difficult to make calls, or the calls are easily dropped, and the data rate is slow, and a large number of complaints rise.

Although this transmission status can be improved or even solved through transmission capacity expansion or refined management, it is difficult to change the transmission status in the short term. Some typical processing methods at present are mainly implemented by transmission congestion control. This method is to detect the transmission quality between a site device and the core equipment room from the perspective of a single device. If the packet loss exceeds a certain threshold, the device will actively Discard some low-priority packets to reduce the overall traffic from the site to the core computer room; this method can achieve better results when a transmission network only carries products of a single manufacturer and a single standard. Usually, each site synchronizes the traffic. After dropping to a certain level, the transmission quality of the site is improved, and the user's perception becomes better.

But the current status quo is: a transmission network carries products of different manufacturers and different standards, and even non-wireless devices. First, not all manufacturers' devices have congestion control functions. Second, even if different manufacturers and different devices have congestion control mechanisms, but Different manufacturers have different transmission congestion control activation strategies, control steps, and control objectives. In actual operation, even the transmission bandwidth or processing capacity given up by a certain site is immediately preempted by other equipment; the overall control is difficult to be effective, resulting in the current situation. The phenomenon is that the number of packets on the transmission network exceeds the processing capacity or the traffic exceeds the receiving buffering or sending buffering capacity of each intermediate transmission node, resulting in high-priority packets also showing high loss rate and large delay. Business impact, especially the inability to make calls during working hours often results in a large number of complaints or loss of customers.

Detailed ways

It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

The main solution of the embodiment of the present invention is to periodically detect the transmission quality of the IUB interface between the base station and the controller, and count service packet transmission performance parameters according to the IUB interface transmission quality, where the service packet transmission performance parameters are at least Including: service packet transmission loss rate; when the service packet transmission performance parameter in the current detection period reaches a preset condition, controlling the base station and the controller to discard some preset low-priority service packets according to a preset ratio to reduce The IUB interface transmits traffic, and the base station and the controller are controlled to send multiple intervals of preset high-priority service messages on the IUB interface, and the anti-IUB interface bad transmission scheme used in the present invention is used in the current part of the operation. Under the high loss rate and high delay of commercial transmission, it can reduce the loss rate of important packets on the IUB interface without increasing the delay, improve service performance, reduce call drop rate and call completion rate, thereby improving service quality and customer satisfaction.

In the prior art, a transmission network carries products of different manufacturers and different standards, and even non-wireless devices, resulting in too many packets on the transmission network exceeding the processing capacity or traffic exceeding the receiving buffer or sending buffer capacity of each intermediate transmission node. , resulting in high loss rate and large delay of high-priority packets, which will affect normal services. In particular, failure to make calls during working hours often results in a large number of complaints or customer loss.

The present invention provides a solution, which can effectively counteract the poor transmission of the IUB interface between the base station and the controller, and improve service quality and user satisfaction.

Specifically, as shown in FIG. 1 , a first embodiment of the present invention proposes a data transmission method, including:

Step S101: Periodically detect the transmission quality of the IUB interface between the base station and the controller, and count service packet transmission performance parameters according to the IUB interface transmission quality, where the service packet transmission performance parameters at least include: service packet transmission loss rate ;

Among them, the IUB interface is the logical interface between the RNC (radio network controller) and the Node B (mobile base station). The full English name is Interface between the RNC and the Node B. The IUB interface completes the user data transmission between the RNC and the Node B. , processing of user data and signaling, and O&M in Node B logic. It is a standard interface that allows interconnection of different manufacturers.

The functions of the IUB interface include: managing the transmission resources of the IUB interface, Node B logic operation and maintenance, transmission operation and maintenance signaling, system information management, dedicated channel control, common channel control and timing, and synchronization management.

Specifically, as shown in FIG. 2, FIG. 2 is a schematic diagram of the network structure of the UMTS system. The network elements of the UMTS system include: UE (User Equipment) and UTRAN (UMTS Terrestrial Radio Access Network, UMTS), wherein:

The UE is a user terminal equipment, which mainly includes a radio frequency processing unit, a baseband processing unit, a protocol stack module, and an application layer software module. The UE exchanges data with network devices through the Uu interface, and provides users with various service functions in the circuit domain and packet domain, including ordinary voice, data communication, mobile multimedia, and Internet applications (such as E-mail, WWW browsing, FTP, etc.).

UTRAN, namely Terrestrial Radio Access Network, is divided into two parts: base station (Node B) and radio network controller (RNC).

Among them, the air interface is between the UE and the NodeB, and the IUB interface is between the NodeB and the RNC, which is carried on the transmission network. Receive the message sent by the RNC through the IUB, and send it to the UE on the air interface in an appropriate manner.

As shown in FIG. 3 , FIG. 3 is a schematic diagram of a typical RRC connection establishment process when a UE calls.

When the UE is calling, it first initiates an RRC connection request to the RNC through the air interface, and the base station receives the UE's message and sends it to the RNC through the IUB interface.

After the RNC receives the RRC connection request from the UE, after judging, it responds to the UE RRCconnection setup through the IUB interface, which is usually three packets on the IUB interface. After the NodeB receives it, it sends it to the UE through the air interface.

After receiving the RRC connection setup, the UE responds to the RNC RRC connection setupcomplete through the air interface, and the NodeB forwards the RNC through the IUB interface after receiving it.

In the above process, if any packet is lost in the middle, the whole process fails, which means that the user fails to call, and the user can only call again.

The solution in this embodiment mainly controls the transmission of service packets on the IUB interface between the base station and the controller, and reduces the loss rate of important packets during transmission on the existing network without increasing the existing delay.

Specifically, first, periodically detect the transmission quality of the IUB interface between the base station and the controller, and count service packet transmission performance parameters according to the IUB interface transmission quality, where the service packet transmission performance parameters may include: service packet transmission loss rate and delay.

Step S102, when the service packet transmission performance parameter in the current detection period reaches a preset condition, control the base station and the controller to send or discard the service packet according to a preset priority and a preset rule.

For example, when the service packet transmission performance parameter in the current detection period reaches a preset condition, control the base station and the controller to discard some preset low-priority service packets according to a preset ratio to reduce the transmission traffic of the IUB interface, and, The base station and the controller are controlled to send multiple intervals of preset high-priority service packets on the IUB interface.

As an embodiment, the packet transmission performance parameter includes: a service packet transmission loss rate, and the service packet transmission performance parameter reaching a preset condition includes: the service packet transmission loss rate is higher than a set threshold.

The specific control process is as follows:

First, periodically detect the transmission quality of the IUB interface between the base station and the controller, and count the transmission loss rate.

When the transmission loss rate in the latest detection period is higher than the set threshold, the base station and the controller actively discard some low-priority service packets according to a certain proportion, reducing the transmission traffic of the IUB interface;

When the transmission loss rate in the latest detection period is higher than the set threshold, the base station and the controller take the initiative to send the important packets on the IUB interface at multiple intervals on the IUB interface.

Subsequently, in the next detection cycle, the detection and operation are continued to be performed cyclically from step S101.

As another implementation manner, the packet transmission performance parameter includes: service packet transmission loss rate and delay, and the service packet transmission performance parameter reaching a preset condition includes: the service packet transmission loss rate and time delay The delay is higher than the corresponding set threshold.

The specific control process is as follows:

First, periodically detect the transmission quality of the IUB interface between the base station and the controller, and count the transmission loss rate and delay.

When the transmission loss rate and delay in the latest detection period are higher than the corresponding set thresholds, the base station and the controller actively discard some low-priority service packets according to a certain proportion, reducing the transmission traffic of the IUB interface;

When the transmission loss rate and delay in the latest detection period are both higher than the corresponding set thresholds, the base station and the controller actively send the important packets on the IUB interface for multiple intervals on the IUB interface.

Subsequently, in the next detection cycle, the detection and operation are continued to be performed cyclically from step S101.

It should be noted that, in other embodiments, the case where the packet transmission performance parameter only includes the delay can also be considered, that is, whether the delay reaches a preset threshold value is used as a judgment condition for triggering the sending or discarding of control service packets.

Further, it may also be considered whether the current actual sending bandwidth is higher than the set threshold value, so as to improve the accuracy of the packet control. The specific implementation is as follows:

When the transmission loss rate in the latest detection period is higher than the set threshold, judge whether the current actual sending bandwidth of the IUB interface is higher than the set threshold; if the current actual sending bandwidth is higher than the set threshold value, the base station and the controller are controlled to actively discard some preset low-priority service packets according to a preset ratio to reduce the transmission traffic of the IUB interface.

In this embodiment, through the above solution, the transmission quality of the IUB interface between the base station and the controller is periodically detected, and the service packet transmission performance parameters are counted according to the transmission quality of the IUB interface, and the service packet transmission performance parameters in the current detection period are calculated. When the preset condition is reached, control the base station and the controller to discard some preset low-priority service packets in a preset ratio to reduce the transmission traffic of the IUB interface, and control the base station and the controller to perform preset on the IUB interface The high-priority service message is sent multiple times at intervals, and the invention adopts the anti-IUB interface bad transmission scheme used in the present invention. Under the current situation of high loss rate and high delay transmission by some operators, it can reduce the IUB interface important message. Loss rate without increasing delay, improve service performance, reduce call drop rate and call completion rate, thereby improving service quality and user satisfaction.

As shown in FIG. 4 , a second embodiment of the present invention proposes a data transmission method. Based on the above-mentioned first embodiment, the method further includes:

Step S103, when the service message transmission performance parameter in the current detection period is reduced to less than the preset condition, control the base station and the controller to stop discarding some preset low-priority service packets and stop performing preset high-priority service packets. Service packets are sent at multiple intervals.

The above step S102 is S1021, when the service packet transmission performance parameter in the current detection period reaches the preset condition, the base station and the controller are controlled to discard some preset low-priority service packets according to a preset ratio to reduce the transmission of the IUB interface. traffic, and control the base station and the controller to send multiple intervals of preset high-priority service packets on the IUB interface.

Compared with the above-mentioned embodiments, this embodiment also includes a processing solution after the transmission performance parameters of subsequent service packets are reduced.

Specifically, taking the packet transmission performance parameters including the service packet transmission loss rate and delay as an example, when the transmission loss rate and delay in the latest detection period are reduced to a certain threshold, the base station and the controller stop actively discarding the low priority part. high-level service packets and stop actively sending important packets at multiple intervals.

Subsequently, in the next detection cycle, the detection and operation are continued to be performed cyclically from step S101.

By adopting the anti-IUB interface bad transmission scheme used in the present invention, under the current situation of high loss rate and high delay transmitted by some operators, the loss rate of important packets of the IUB interface can be reduced without increasing the delay, and the service can be improved. performance, reducing call drop rate and call completion rate, thereby improving service quality and user satisfaction.

The application scenarios of the solutions of the embodiments of the present invention are described in detail below:

Example 1

A South American operator has a single transmission network that supports all 3G and 4G equipment. The wireless equipment comes from three manufacturers. Due to the old transmission and aggregation equipment of a certain model, the packet switching capability is limited and cannot meet the needs of the existing network. It is not possible to replace the entire network of the equipment within the same time period. The transmission network monitoring from a single manufacturer's equipment shows obvious characteristics of good indicators at night and poor indicators in the daytime. Even high-priority packets are still lost during the day. The rate is still as high as 10-20% or more. The delay jitter is unstable, ranging from tens to hundreds of milliseconds. It is difficult to make calls during the day. The observed RRC connection success rate is also very low, only between 30 and 40%.

After the single-vendor device adopts transmission congestion control, it periodically detects the transmission quality. During the period of high loss rate, it actively discards some low-priority packets, reducing the overall traffic of the IUB interface. The RRC connection success rate indicator has not been significantly changed, and it is difficult to get through the phone. The status quo has not improved significantly. The reason is that after the single-vendor equipment adopts congestion control, the overall transmission traffic is reduced to a certain extent, but the loss rate of the IUB interface is not improved significantly. The IUB interface transmits 5 packets of data. If any packet of data is lost on the IUB interface, the whole process fails. It takes 5 consecutive successes to complete an RRC connection process. Calculated by probability, it is the fifth power of the single success rate. The requirements for one-shot success are high.

Adopt the scheme used in the present invention, and its flow process is as follows:

Step 1. NodeB and RNC detect the transmission quality of the IUB interface at a period of 5 minutes, and count the transmission loss rate and delay.

Step 2: When the transmission loss rate of the IUB interface rises to a certain threshold of 5% in the last 5 minutes, if the actual transmission bandwidth of the current IUB interface is higher than 50% of the set bandwidth, NodeB and RNC actively discard the background according to the ratio of 10% of the set bandwidth. Packets of internal interaction services reduce the total traffic transmitted by the IUB interface.

Step 3: When the transmission loss rate of the IUB interface rises to a certain threshold of 5% in the last 5 minutes, the NodeB and the RNC actively identify the important packets on the IUB interface described in Figure 3, and repeatedly send 2 on the IUB interface at intervals of 10ms. Second-rate.

Step 4: When the transmission loss rate of the IUB interface drops to a certain threshold of 5% in the last 5 minutes, the NodeB and RNC stop actively discarding some low-priority service packets and stop actively sending important packets at multiple intervals.

Continue to cycle from step 1 for periodic detection and operation.

It can be seen from the above example that using the method shown in the present invention, during the high loss period of the IUB interface, the transmission flow is not simply reduced, but also according to the specific conditions of the IUB interface network, the important packets of the IUB interface are repeatedly sent at intervals, as shown in the figure. As shown in Figure 3, after the important message in Figure 3 is sent twice at an interval of 10ms, since any one of the two times can be received, the probability of a single interaction failure is significantly reduced, from 20% to 4%. The chances of this process being successful are greatly increased. After the method shown in the present invention is actually used in a South American operator's network, although the loss rate of the IUB interface is not significantly improved during the day, the call-through rate of the user is greatly increased, and the user no longer complains that the call cannot be made during the day.

Example 2

A domestic operator, a transmission network, first opened the 3G network, and then with the construction of the 4G network, several manufacturers were introduced into the original transmission network. The network gradually monitors that some ports have insufficient bandwidth. Due to the characteristics of mobile networks, 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 needs 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.

In this scenario, a site that has experienced transmission degradation is selected to implement the solution used by the present invention, and the process is as follows:

Step 1. NodeB and RNC detect the transmission quality of the IUB interface at a period of 5 minutes, and count the transmission loss rate and delay.

Step 2: When the transmission loss rate of the IUB interface rises to a certain threshold of 5% in the last 5 minutes, if the actual transmission bandwidth of the current IUB interface is higher than 75% of the set bandwidth, NodeB and RNC actively discard the background according to the ratio of 10% of the set bandwidth. Packets of internal interaction services reduce the total traffic transmitted by the IUB interface.

Step 3: When the transmission loss rate of the IUB interface rises to a certain threshold of 5% in the last 5 minutes, the NodeB and RNC actively identify the important packets on the IUB interface described in Figure 2, and repeatedly send 2 on the IUB interface at intervals of 50ms. Second-rate.

Step 4: When the transmission loss rate of the IUB interface drops to a certain threshold of 5% in the last 5 minutes, the NodeB and RNC stop actively discarding some low-priority service packets and stop actively sending important packets at multiple intervals.

Continue to cycle from step 1 for periodic detection and operation.

With the method shown in the present invention, although the reason and performance of the degradation of IUB transmission quality are different from those of Case 1, after the actual deployment of the site where the degraded IUB transmission is selected, the RRC connection success rate indicator returns to normal, and the telephone call completion rate remains at above a good level.

Correspondingly, an embodiment of the data transmission apparatus of the present invention is proposed.

The data transmission device of the present invention includes:

A parameter detection module, configured to periodically detect the transmission quality of the IUB interface between the base station and the controller, and count service packet transmission performance parameters according to the IUB interface transmission quality, where the service packet transmission performance parameters at least include: transmission loss rate;

The transmission control module is configured to control the base station and the controller to send or discard service packets according to preset priorities and preset rules when the service packet transmission performance parameters in the current detection period reach a preset condition.

Specifically, the transmission control module is further configured to control the base station and the controller to discard some preset low-priority service packets according to a preset ratio when the service packet transmission performance parameter in the current detection period reaches a preset condition, so as to The transmission traffic of the IUB interface is reduced, and the base station and the controller are controlled to send multiple intervals of preset high-priority service packets on the IUB interface.

Further, the transmission control module is also used to judge whether the current actual transmission bandwidth of the IUB interface is higher than the set threshold when the service message transmission performance parameter in the current detection period reaches a preset condition; If it is higher than the set threshold value, the base station and the controller are controlled to discard part of the preset low-priority service packets according to a preset ratio to reduce the transmission traffic of the IUB interface.

Further, the transmission control module is further configured to control the base station and the controller to stop discarding some preset low-priority service packets when the service packet transmission performance parameters in the current detection period are reduced to less than a preset condition. message and stop sending multiple intervals of preset high-priority service messages.

In this embodiment, through the above solution, the transmission quality of the IUB interface between the base station and the controller is periodically detected, and the service packet transmission performance parameters are counted according to the transmission quality of the IUB interface, and the service packet transmission performance parameters in the current detection period are calculated. When the preset condition is reached, control the base station and the controller to discard some preset low-priority service packets in a preset ratio to reduce the transmission traffic of the IUB interface, and control the base station and the controller to perform preset on the IUB interface The high-priority service message is sent multiple times at intervals, and the invention adopts the anti-IUB interface bad transmission scheme used in the present invention. Under the current situation of high loss rate and high delay transmission by some operators, it can reduce the IUB interface important message. Loss rate without increasing delay, improve service performance, reduce call drop rate and call completion rate, thereby improving service quality and user satisfaction.

In addition, an embodiment of the present invention also provides a data transmission device, including: a memory, a processor, and a computer program stored on the memory and executable on the processor, where the computer program is executed by the processor When doing the following:
