technical field

The invention relates to communication technology, in particular to a method and system for controlling network congestion.

Background technique

A computer network is a computer communication system that connects multiple computer systems with independent functions distributed in different locations through communication lines and network equipment, and communicates information according to a certain network protocol to realize resource sharing. Through the Internet, people can easily realize remote information access, communication between users, interactive entertainment, e-commerce and so on.

However, with the surge of network data traffic, network congestion has become more and more serious, which has become a bottleneck restricting network development and application. The root cause of network congestion is that the load provided by end users to the network is greater than the capacity of network resources (buffering, link bandwidth, etc.) and processing capacity, which is manifested by increased packet delay, increased discard probability, and decreased performance of upper-layer application systems. The existing technology is to avoid or reduce the occurrence of network congestion by planning the network at the initial stage of network construction and continuously improving the data processing capability and data forwarding capability of network hardware devices during network use.

However, in the prior art, the network congestion is mainly prevented by continuously expanding the network capacity of the operator. Therefore, the operator needs to invest a large cost to prevent the network congestion.

Detailed ways

The method for controlling network congestion provided by the embodiments of the present invention can be specifically applied when an operator network and multiple terminal devices perform data transmission. The method for controlling network congestion provided in this embodiment can be specifically implemented by a policy controller, a traffic analysis device, and a terminal management system in an operator's network. The policy controller and traffic analysis device can be integrated on the core network or independently Setting, the terminal management system is set on the terminal management platform, and the policy controller, traffic analysis device and terminal management system can be realized by software and/or hardware. Hereinafter, taking WCDMA as an example of the communication system, the method for controlling network congestion provided by this embodiment will be described in detail.

FIG. 1 is a schematic flowchart of a method for controlling network congestion according to Embodiment 1 of the present invention. As shown in Figure 1, the method for controlling network congestion provided in this embodiment specifically includes the following steps:

Step 101, receiving the network quality information sent by the core network equipment and the current service information of the terminal equipment;

In this step, the traffic analysis device receives the information sent by the service gateway (Servicel GateWay, SGW for short) of the core network equipment, the information includes network quality information and current service information of the terminal equipment, wherein the network quality information can be It is the information of the utilization rate of the network port, or the information of the utilization rate of the network bandwidth. The terminal device is a terminal device that has been connected to the core network device and is transmitting data with the core network device. The number of the terminal device is specifically how many One, that is to say, the information received by the traffic analysis device may include service information that multiple terminal devices are performing data transmission with the core network.

Step 102, determine the current network state according to the network quality information, and determine the type information of the service currently being performed by the terminal device and the corresponding flow information according to the service information;

In this step, the traffic analysis device analyzes the network quality information, specifically by analyzing the information of network port utilization or network bandwidth utilization, to determine whether the network status is network congestion or network normal. The traffic analysis device also conducts in-depth analysis on the ongoing business information of each terminal equipment to determine the type of data service that the terminal equipment is running and the traffic information of the business that the terminal equipment is running. For example, the business type can be Roughly divided into operator business and non-operator business, it can also be subdivided into BT download service or "permanent online" service QQ, etc. This embodiment does not limit the classification of service types, and those skilled in the art can Classify the business type according to the situation. The traffic information is the bandwidth value actually occupied by the service running on the terminal device or the amount of data to be transmitted during operation, wherein each terminal device can perform multiple service types at the same time. For example, there are n terminal devices connected to the core network device, n is a positive integer i=1, 2, 3...n, among them, there are m services running on the i-th terminal device, m is a positive integer k= 1, 2, 3...m, by analyzing the kth business information running on the i-th terminal device, it can be determined that the business type of the k-th business currently being carried out by the i-th terminal device is BT download and The bandwidth value actually occupied by the running BT download service or the amount of data to be transmitted.

Step 103, according to the type information and/or corresponding traffic information, determine whether there is a signaling storm risk in the terminal device;

The executive body of this step is the terminal management system. The business type with signaling storm risk can be the business type that is online for a long time and sends information to the server every few seconds or minutes to maintain its online status, such as QQ, MSN and other real-time Communication services can also be services that require more bandwidth for data transmission, such as BT downloads. There is no restriction on the type of service here. The terminal management system can determine the existence of signaling for terminal devices that are currently performing these types of services according to the type of service. storm risk. It is also possible to compare the data traffic of the data transmission of the service with the first preset value, and when the data traffic of the data transmission of the service is greater than the first preset value, it is determined that the terminal equipment performing the service has a signaling storm risk, Wherein the first preset value may be an experience value of relevant technical personnel. It may also be determined that the sum of data transmission data volumes of services that may have a signaling storm risk is greater than a second preset value as having a signaling storm risk, where the first preset value and the second preset value may be Differently, this embodiment does not limit the method of determining whether there is a signaling storm risk according to traffic information.

Step 104, if the current network status is non-congested and the terminal device has a risk of signaling storm, perform downgrade processing on the terminal device or the services currently being performed by the terminal device that have the risk of signaling storm.

The executive body of this step is the terminal management system. The risk of signaling storm refers to the risk of network congestion, which means that the quality of network transmission data is significantly reduced, such as increased packet delay and increased probability of packet discarding. The non-congested state can be a situation where the network state is better, or it can be a state that is close to congestion but no congestion has occurred yet. Those skilled in the art can determine the situation that needs to be degraded according to the actual situation. For example, the non-congested state can be that the network state is relatively low In a good situation, or the terminal management system compares the quality information of the network with a preset threshold, and determines that the network state less than the preset threshold is a non-congested state, and if the quality information of the network is greater than the threshold, the existing The terminal or terminal equipment at the risk of signaling storm is currently performing downgrade processing that may cause the risk of signaling storm. Limit or close the storm risk business, and there is no limit to the downgrading process here.

In this embodiment, the terminal equipment that has the risk of signaling storm is determined through the type of service that is running on the terminal equipment that has connected to the core network and the traffic information corresponding to the service. When the network is not congested, the terminal management system Or the current service of the terminal device that has the risk of signaling storm is downgraded, so that the network congestion can be effectively defended, thereby reducing the operator's investment cost for defending the network congestion.

In step 104 of the above-mentioned embodiment, the downgrading process is performed on the terminal device or the service currently being carried out by the terminal device that has a risk of signaling storm, including:

The priority processing information is sent to the policy controller, so that the policy controller performs degraded processing on the terminal equipment with signaling storm risk or the terminal equipment is currently performing a service with signaling storm risk.

For example, the policy controller may perform downgrade processing on a terminal device determined to have a signaling storm risk, for example, perform downgrade processing on a terminal device running an instant messaging service or an instant messaging service running on the device, so as to allocate Lower resources are assigned to the terminal device or the access rate of the terminal device is reduced, and lower resources can also be allocated to the instant messaging service or the access rate of the instant messaging service is reduced.

Optionally, before sending the priority processing information to the policy controller, it also includes:

According to the traffic information, sort and process the services currently being carried out by the terminal equipment that have the risk of signaling storm, and obtain the business sort information;

Send the priority processing information to the policy controller, so that the policy controller can downgrade the services currently being carried out by the terminal equipment that have the risk of signaling storm, including:

The priority processing information including the service ranking information with signaling storm risk is sent to the policy controller, so that the policy controller performs degraded processing on the currently ongoing services of the terminal device with signaling storm risk according to the service ranking information.

Specifically, in this step, according to the size of the data traffic in the traffic information of the services with signaling storm risks that the terminal equipment is currently carrying out, it can be sorted in descending order, or by weighted sorting and other methods. The traffic information of the services with signaling storm risks can be sorted in any sorting manner that a person skilled in the art can think of. For example, the terminal management system sends to the policy controller the priority processing information determined according to the service flow information with signaling storm risk, and then the policy controller can one by one the running on the terminal device according to the priority order The business is downgraded. Specifically, the business that is running on the terminal equipment of some services that will be ranked higher in the priority order of the business with the risk of signaling storm can be downgraded, or there will be a signaling storm. In the ranking of risks, the services on all terminal devices corresponding to the business are downgraded. The services running on the terminal devices can also be downgraded to different degrees according to the order of the ranking. That is, the higher the ranking, the lower the downgrade level. Low.

Step 103 may specifically include:

If the traffic information corresponding to at least one type of information exceeds the first preset threshold, it is determined that the terminal device has a signaling storm risk; and/or,

If the sum of the traffic information corresponding to each type of information exceeds the second preset threshold, it is determined that the terminal device has a signaling storm risk.

Specifically, the terminal management system determines whether there is a signaling storm risk in the terminal device according to the service type information that the terminal is running and the corresponding traffic information. There are two implementation methods: 1. Among the n terminal devices that are connected to the core network , n is a positive integer i=1, 2, 3...n, if there are d services that may cause signaling storms in the i-th terminal device, where d is a positive integer, in the d services When the data flow of at least one of the services exceeds the first preset threshold, it is determined that the i-th terminal device has a signaling storm risk; 2. If d of the i-th terminal devices are running, there may be signaling storms storm business, and the sum of the data traffic of the d business exceeds the second preset threshold, it is determined that the i-th terminal device has a signaling storm risk. The above-mentioned first preset threshold and second preset threshold can be determined by those skilled in the art according to the analysis of the service model.

Optionally, in step 104, before downgrading the services currently being performed by the terminal device that have signaling storm risks, the method further includes:

Determine whether the type information includes the operator's own business type;

If it is included, then downgrade the services that the terminal equipment is currently conducting that have the risk of signaling storms, including:

Downgrade the non-operator's own services that are currently running on the terminal device and have the risk of signaling storms.

Specifically, when the current network status is non-congested and the terminal device is running a service with signaling storm risk, when the terminal management system sends a notification to the policy controller about the terminal device with signaling storm risk or the terminal device's current Before downgrading the ongoing service with the risk of signaling storm, it is determined whether the service information includes the operator's own service type according to the service type information that the terminal device is running. If the terminal equipment runs a signaling storm risk business type that includes the operator's own business, the non-operator's own business that the terminal equipment is currently running can be downgraded to limit the operation on the terminal equipment. The data transmission traffic of the non-operator's own business that has the risk of signaling storm does not limit the specific implementation method of the downgrade processing, thereby ensuring the use of the operator's own business in the network.

Optionally, if the current network state is a congested state and the terminal device has a risk of a signaling storm, the method further includes:

Shut down at least one service that the terminal device is currently conducting that has a risk of signaling storm; or,

Perform current limiting processing on at least one service that has a signaling storm risk currently being performed by the terminal device.

Specifically, when the network state is a congested state, that is, when the network port utilization rate is greater than a preset value or the network bandwidth utilization rate is greater than another preset value, the terminal management system first obtains from the traffic analysis device before network congestion At one moment, the service type information and/or corresponding traffic information running on the terminal device, and then, the terminal management system will close the terminal device with signaling storm risk or limit the traffic of the terminal device currently running with signaling storm risk The policy controller sends the information to the policy controller, and the policy controller then sends the information to the core network's general packet radio service support node (Serving GPRS SUPPORT NODE, referred to as SGSN) or general packet radio service gateway support node (Gateway GPRS Support Node, GGSN for short) closes the service, or restricts the service, and can also remind the terminal equipment to close the service.

Optionally, shutting down at least one service with a risk of signaling storm currently being performed by the terminal device; or, before limiting the flow of at least one service with a risk of signaling storm currently being performed by the terminal device, further includes:

Determine whether the type information includes the operator's own business type;

If it is included, then close at least one service with signaling storm risk currently being performed by the terminal device; or, perform flow-limiting processing on at least one service with signaling storm risk currently being performed by the terminal device, including:

Shut down at least one non-operator-owned service that the terminal device is currently conducting that has the risk of signaling storm; or, limit the flow of at least one non-operator-owned service that the terminal device is currently conducting that has the risk of signaling storm deal with.

Optionally, after step 104, the terminal management system sends prompt information to the terminal device to remind the terminal device that at least one ongoing service with signaling storm risk is closed or traffic limited.

Specifically, when the terminal management system sends information to the policy controller that needs to close or limit the flow of at least one service with signaling storms running on the terminal equipment, the policy controller sends the information to the core network at the same time, and through The core network limits or shuts down at least one service with signaling storms running on the terminal device. At the same time, the terminal management system can also send a prompt message to the terminal device to inform the terminal management system that it is shutting down or limiting the traffic. At least one ongoing service on the terminal device that has the risk of a signaling storm.

In the process of congestion prevention and congestion handling in this embodiment, it is judged whether there is an operator's own service on the service information with signaling storm, which can effectively prevent congestion and deal with congestion.
