Communication control method and device

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for communication control.

Background

When a network security event occurs, a communication network needs to be regulated so as to maintain the security of a network space.

In the prior art, there are a control scheme for a fourth generation (4th generation, 4G) network and a control scheme for a fifth generation (5th generation, 5G) network, but since the deployment manner and signaling flow of the 5G network are greatly different from those of the 4G network, a terminal controlled in the 5G network cannot guarantee that the terminal is still controlled after moving to the 4G network, that is, if the terminal controlled in the 5G network moves to the 4G network, a problem of communication control loss occurs, in this case, part of the terminals controlled in the 5G network actively move from the 5G network to the 4G network to avoid the control, so that the network security is threatened.

Disclosure of Invention

The application provides a communication control method and a communication control device, which can solve the problem of communication control loss.

In order to achieve the purpose, the following technical scheme is adopted in the application:

in a first aspect, the present application provides a method for communication regulation, including: the first network equipment receives first indication information from the second network equipment, wherein the first indication information is used for indicating the regulation state of the second network equipment; the first network equipment is network equipment in a fifth generation 5G network; the second network equipment is network equipment in a fourth generation 4G network; the method comprises the steps that a first network device determines whether a control state of the first network device and a control state of a second network device meet preset conditions or not; and if so, the first network equipment sends second indication information to the second network equipment, wherein the second indication information is used for indicating the second network equipment to execute a tracking area update TAU process of the terminal equipment moving from the 5G network to the 4G network.

Based on the above technical solution, the method provided in the embodiment of the present application determines whether the mobile device is capable of moving by comparing the regulation states of the first network device and the second network device. And only when the regulation state of the first network equipment and the regulation state of the second network equipment meet the preset condition, the regulated terminal accessed to the 5G network is allowed to be accessed to the 4G network. In this case, after moving from the 5G network subjected to the communication regulation to the 4G network, the regulated terminal is still subjected to the communication regulation, that is, continuity of the communication regulation of the terminal from the 5G network to the 4G network is realized; if the difference between the control information of the 4G and the control information of the 5G is not within a certain preset interval, movement is refused, so that the problem that communication control is lost after the terminal moves to the 4G network from the 5G network subjected to communication control can be avoided, or the problem that the terminal actively moves to the 4G network from the 5G network to avoid control is avoided, and the terminal can be controlled more accurately, so that network safety is maintained.

In a possible implementation manner, if the regulation state of the first network device and the regulation state of the second network device do not satisfy the preset condition, third indication information is sent to the second network device, where the third indication information is used to indicate the second network device not to execute a TAU procedure in which the terminal device moves from the 5G network to the 4G network.

In this implementation manner, the first network device determines whether itself is in the controlled state, and sends the fifth indication message to the second network device only if the first network device is in the controlled state, so that the first network device being in the controlled state is a precondition for the first network device sending the fifth indication message to the second network device, and communication waste caused by the first network device sending the fifth indication message to the second network device when the first network device is not in the controlled state is avoided.

In a possible implementation manner, if the second network device receives the third indication information from the first network device, the second network device does not perform the TAU procedure of moving the terminal device from the 5G network to the 4G network.

In a possible implementation manner, before the second network device sends the first indication information to the first network device, the method further includes: and the second network equipment receives a fifth indication message from the first network equipment, wherein the fifth indication message is used for indicating the second network equipment to send the regulation information of the second network equipment to the first network equipment.

At present, the existing regulation schemes for the second Generation (2th Generation, 2G) network, the 3G network, the 4G network, and the fixed telephone network can be represented with reference to the scheme in fig. 4.

S401, the operator platform receives the control command and sends the control command to the network management platform. Correspondingly, the network management platform receives the control command from the operator platform.

Wherein the policing command is used to characterize the particular traffic of the particular terminal that is being policed within the particular area.

S402, the network management platform sends a control command to the network equipment connected with the specified terminal in the specified area. Correspondingly, the network equipment connected with the appointed terminal in the appointed area receives the control command from the network management platform.

The network management platform sends the control command to the network equipment in a mode of sending the indication message. Optionally, the network device may also be set in a manual setting manner by an operator, that is, the network device is set to the regulation state according to the regulation command.

The network devices may include, but are not limited to, the following network devices:

a Mobile Switching Center (MSC) for controlling base station equipment connected to a wireless terminal in an area.

An Access Gateway Control Function (AGCF) for controlling an Integrated Access Device (IAD) device connected to a fixed telephone of h.248 format in a specified area.

A system broadcast channel/proxy session control function (SBC/pcsccf) configured to control an Optical Node (ONU) device that connects a fixed telephone of an SIP format and a terminal in a designated area.

S403, the network device sends the policing command to the access network devices controlled by the network device. Accordingly, the access network device controlled by the network device receives the policing command from the network device.

S404, the access network equipment regulates the appointed terminal according to the regulation command.

The above-mentioned regulation scheme which is only 2G network/3G network/4G network/fixed telephone, because the regulation scheme of 2G network/3G network/4G network/fixed telephone has universality, therefore, after the regulated terminal is regulated in the 4G network, it can also be regulated in the 2G network/3G network/fixed telephone.

The deployment mode and the signaling flow of the 5G network are different from those of the previous network, so the control scheme of the 4G network is not applicable to the 5G network, that is, the control command cannot be commonly used in the 4G network and the 5G network, so that the terminal controlled in the 5G network cannot ensure that the terminal is still controlled after moving to the 4G network, which causes the problems of communication control loss or discontinuous communication control, etc.

In order to solve the problems in the prior art, an embodiment of the present application provides a communication control method, which can solve the problem of communication control loss. As shown in fig. 5, the method includes:

s501, the second network equipment sends first indication information to the first network equipment. Accordingly, the first network device receives the first indication information from the second network device.

The first indication information is used for indicating the regulation state of the second network equipment. The policing state may include current policing information (e.g., current policing network speed: 100kb/s, current policing latency: 150ms), policing policy (e.g., policing network speed ranging from 100kb/s to 200kb/s, policing latency ranging from 100ms to 150 ms).

The first network device is a network device in a 5G network, and the second network device is a network device in a 4G network. Illustratively, the first network device may be an AMF and the second network device may be an MME.

It should be noted that the scheme provided in the present application is also applicable to a scenario where the first network device is a network device in a 4G network and the second network device is a network device in a 5G network, and the specific process can be understood with reference to the scheme when the first network device is a network device in a 5G network and the second network device is a network device in a 4G network.

S502, the first network device determines whether the control state of the first network device and the control state of the second network device meet preset conditions.

In a possible implementation manner, the preset condition may refer to that a difference value of parameters of the regulation state of the first network device and the regulation state of the second network device is within a preset interval.

For example, the parameter of the policing state is the wire speed. Illustratively, the parameter of the policing state of the first network device is 100kb/s, the parameter of the policing state of the second network device is 110kb/s, the preset interval is set to (-20kb/s, +20kb/s), and the parameter difference between the two is 10 kb/s. Comparing, it can be known that the parameter difference between the first network device and the second network device is within the preset interval, and the parameter of the control state of the first network device and the parameter of the control state of the second network device are considered to meet the preset condition.

For example, the parameter of the policing state is a time delay. Illustratively, the parameter of the policing state of the first network device is 150ms, the parameter of the policing state of the second network device is 153ms, the preset interval is set to (-5ms, +5ms), and the parameter difference between the two is 3 ms. Comparing, it can be known that the parameter difference between the first network device and the second network device is within the preset interval, and the parameter of the control state of the first network device and the parameter of the control state of the second network device are considered to meet the preset condition.

It should be noted that, the above two exemplary descriptions are only two examples of the parameter of the policing state, and the parameter of the policing state may also include other parameters, such as traffic, etc., and the present application is not limited thereto.

In another possible implementation manner, when the regulation status of the first network device is call restriction, the preset condition may be set as whether the call restriction modes of the first network device and the second network device are consistent. Illustratively, the policing state of the first network device is to restrict the call, and the policing state of the second network device is also to restrict the call. And comparing to see that the control states of the first network device and the second network device are both call restriction states, and determining that the control state of the first network device and the control state of the second network device meet the preset condition.

In another possible implementation manner, when the regulation state of the first network device is to limit the enterprise network traffic, the preset condition may be set to whether the call-limiting modes of the first network device and the second network device are consistent or not. Illustratively, the policing state of the first network device is to restrict enterprise network traffic and the policing state of the second network device is to restrict enterprise network traffic. And comparing to see that the control states of the first network device and the second network device are both limiting enterprise network services, and then determining that the control state of the first network device and the control state of the second network device meet the preset condition.

It should be noted that the preset condition may also be to limit logging in of some websites, limit using of some application programs, limit services of the internet of things, and the like, and the present application is not limited.

It should be noted that whether the regulatory state of the first network device and the regulatory state of the second network device satisfy the preset condition includes the following two cases: in case 1.1, the control state of the first network device and the control state of the second network device meet a preset condition; in case 1.2, the regulation state of the first network device and the regulation state of the second network device do not satisfy the preset condition.

The actions performed by the first network device in different situations are different, and are specifically described as follows:

in case 1.1, the regulation state of the first network device and the regulation state of the second network device satisfy the preset condition.

In case 1.1, the first network device performs the following S503.

S503, the first network device sends second indication information to the second network device. Accordingly, the second network device receives the second indication information from the first network device.

The second indication information is used for indicating the second network device to execute the TAU procedure of the terminal device moving from the 5G network to the 4G network.

In case 1.2, the first network device performs the following S504.

S504, the first network device sends third indication information to the second network device. Accordingly, the second network device receives the third indication information from the first network device.

The third indication information is used for indicating the second network device not to execute the TAU procedure of the terminal device moving from the 5G network to the 4G network. In this case, the first network device also does not perform the TAU procedure of moving the terminal device from the 5G network to the 4G network, and may lock the terminal to the 5G network and cause the terminal to drop in the 5G network due to the network being poor.

The application provides a communication control method, which judges whether the mobile communication is possible or not by comparing control states of a first network device and a second network device. And only when the regulation state of the first network equipment and the regulation state of the second network equipment meet the preset condition, the regulated terminal accessed to the 5G network is allowed to be accessed to the 4G network. In this case, after moving from the 5G network subjected to the communication regulation to the 4G network, the regulated terminal is still subjected to the communication regulation, that is, continuity of the communication regulation of the terminal from the 5G network to the 4G network is realized; if the difference between the control information of the 4G and the control information of the 5G is not within a certain preset interval, movement is refused, so that the problem that communication control is lost after the terminal moves to the 4G network from the 5G network subjected to communication control can be avoided, or the problem that the terminal actively moves to the 4G network from the 5G network to avoid control is avoided, and the terminal can be controlled more accurately, so that network safety is maintained.

In a possible implementation manner, with reference to fig. 5, before the foregoing S501, the method may further include the following S601.

S601, the first network device sends a fifth indication message to the second network device. Accordingly, the second network device receives the fifth indication message from the first network device.

The fifth indication message is used for indicating the second network device to send the regulation information of the second network device to the first network device.

The first network device needs to send a fifth indication message to the second device to indicate the second network device to send the control information of the second network device to the first network device, because the second network device is requested to send the information first, the second network device can send the control information of the second network device, and parameters are provided for the comparison of the control state of the first network device and the control state parameters of the second network device subsequently.

In a possible implementation manner, with reference to fig. 5, before S601, the method may further include the following S602 to S604.

S603, the first network device sends a fifth indication message to the second network device. Accordingly, the second network device receives the fifth indication message from the first network device.

In case 2.1, the first network device performs the following S604.

S604, if the first network device does not send the fifth indication message to the second network device, continuing to execute the subsequent process of the TAU.

The application provides a communication control method, wherein a first network device judges whether the first network device is in a control state, and if the first network device is in the control state, a fifth indication message is sent to a second network device, so that the first network device is in the control state, which is a precondition that the first network device sends the fifth indication message to the second network device, and communication waste caused by the fact that the first network device sends the fifth indication message to the second network device when the first network device is not in the control state is avoided.

In an implementation manner, as shown in fig. 6, taking a first network device as an AMF, a second network device as an MME, and a terminal in an idle state as an example, a communication control method provided in this embodiment is specifically described as follows:

Wherein, the TAU triggering information is used for requesting to execute the TAU flow.

S702, the eNB sends TAU triggering information to the MME. Correspondingly, the MME receives TAU trigger information from the eNB.

S703, the MME sends connection request information to the AMF. Accordingly, the AMF receives the connection request information from the MME.

The MME sends, to the AMF, connection request information through an N26 interface, where the connection request information is used to obtain information about the terminal in the 5G network.

It should be noted that the information related to the terminal in the 5G network may include an identifier of the terminal and latitude and longitude information of the terminal.

S704, the AMF judges whether to send a fifth indication message to the MME or not according to the self control state.

It should be noted that the policing state of the AMF includes the following two cases: case 3.1, AMF is in a regulated state; case 3.2, AMF is not in a regulated state.
