As shown in FIG. 1 , this embodiment provides an access control method, where the method includes:

Step S100: The first node sends the indication information to the second node by using the downlink channel.

The indication information includes at least one of the following:

Wherein the first node and the third node belong to the first node, and the second node belongs to the second type node

The access control method described in this embodiment is implemented as a first node. The first node may be one of a macrocell, a microcell, a picocell, a femtocell, a low power node (LPN), and a relay. The femto base station may also be referred to as a home base station.

Before the method of the embodiment sends the indication information, the method further includes acquiring the indication information. The indication information may be formed autonomously by the first node, or may be received from another communication node, for example, the macro base station receives the indication information and the like from the mobility management entity MME.

The current load level is used to assist the second node to determine whether to access the first node; the configuration information is used to assist the second node to determine whether to access the third node.

The configuration information of the K third nodes may be used by the second node to determine whether there is a first type of node available for access in the third node.

The delay information is indication information indicating that the second type of node delays transmitting random access signaling. After receiving the delay information, the second node delays sending the random access signaling, so as to prevent the second type of node that is too current at the current time to send a random access signaling to the first node. Congestion caused by it. The random access signaling is information for requesting random access sent by the second type of node to the first type of node.

The first node sends the indication information to the second node by using a downlink channel. The second node includes a group or a communication terminal; the type of the second node may include at least one of the following:

The second node of Human to Human (H2H);

The second node of the Machine to Mechine (M2M);

a second node of a vehicle to vehicle (V2V);

The second node of Device to Device (D2D).

The type of the second node here may be a terminal type. A representative representative of the second node of the H2H may include a mobile phone or the like. The second node of the M2M is typically a node capable of communication between machines. The second node of the vehicle to the vehicle includes an in-vehicle communication node. The D2D node is a device-to-device communication node. D2D communication means that the terminal can directly communicate without going through the base station, and each D2D communication link occupies the same resources as one cellular communication link, which can improve resource utilization and network capacity. M2M is a research hotspot of the fifth mobile 5G communication, including not only direct communication between terminals, but also communication between various machines.

The indication information includes at least one of load level information and configuration information of K third nodes. If the first node described in this embodiment is executed as the node A, the K third nodes are the node B except the node A.

In this embodiment, the load level information describes the current load level of the node A. Configuration information of the Node B described by the configuration information of the K third nodes.

The load level information may be used to assist the second node to determine whether to access the node; and the configuration information is used by the second node to determine whether to access the node B.

The first node in this embodiment can control the access of the second node by using the indication information. The first node may send the indication according to its own load condition Information, thereby avoiding the phenomenon of node access congestion caused by excessive second node access; and by transmitting the configuration information of the K third nodes, the second node can be conveniently selected according to the configuration information. The other first nodes that are accessed, in this way, ensure the access of the second node, and at the same time achieve load balancing before the plurality of first nodes.

Specifically, the sending, by the first node, the indication information to the second node by using the downlink channel, includes: carrying the indication information in a system message and sending.

In the embodiment, the indication information is sent in the system message, so that the second node receives the indication information when receiving the system message, so that the first node does not need to send through special information. The number of information interactions between the first node and the second node is reduced, and the power consumption of the second node is saved. In a specific implementation process, the indication information may also be sent in a radio resource control RRC message. Of course, the indication information can also be sent by dedicated signaling.

The load of the first node may include N load levels, and the load level information may be one of N load levels, characterizing the current load level of the first node.

The configuration information of the K third nodes includes at least one of the following:

a sector number of the K third nodes; the sector number may be used to identify a corresponding first node, where the configuration information includes a sector number of each of the K third nodes.

Geographical location information of the K third nodes;

Load level information of the K third nodes;

Type indication information of the second node supported by the K third nodes;

The service type indication information supported by the K third nodes.

The geographical location information includes geographic location information of each of the K third nodes, so that the second node can determine which first node is located in the vicinity of the first node.

The load level information is a load level of each of the K third nodes.

The delay information includes at least one of the following:

Delayed transmission of the enable information;

Delayed transmission of time indication information.

The delay enable information can be used to indicate whether the delay information is valid. For example, the delayed transmission enable information includes 1 bit. When the bit is 1 indicating that the delay information is valid, the second type of node may determine the delay time according to the delayed transmission time indication information of the delay information. Or the time at which the random access signaling is sent. If the bit is 0, the delay information is invalid. Even if the delay information includes delayed transmission time indication information, the second node does not delay according to the delayed transmission time indication information.

The method of this embodiment further includes: configuring the delay information according to at least one of the following: a service type of the second type of node; a type of the second type of node; and a working mode of the second type of node.

It is obvious that the configuration of the delay information herein is a sub-step or a sub-step of forming the indication information. The delay information in the embodiment will configure the service type of the second type of node, the type of the second type of node, and the working mode of the second type of node, and configure the delayed sending time indication information in the delay information. The information duration of the delay enable information in the delay information may also be configured. In this case, the first node can control parameters such as the time at which the second type node sends the random access signaling by sending the delay information.

The type of the second node may include D2D, H2H, V2V, M2M, and the like. The type indication information of the second node that is prohibited from accessing, indicating that a second node of a certain type is not allowed to access. It is worth noting that the type of the second node herein may refer to the terminal type of the second node.

The second node has multiple working modes, such as coverage enhanced mode and non-coverage. Enhanced mode and regular mode. The coverage enhancement mode is an operational mode capable of being connected to a cell employing coverage enhancement techniques. The non-coverage enhancement mode is capable of connecting to a working mode that does not employ overlay enhancement techniques. The normal mode is a working mode configured by a second type of node by default, and the regular mode may be one of the coverage mode or the non-coverage enhanced mode, but the default mode configured by default for the second type of node, The second node cannot know whether the coverage mode is the coverage mode or the non-coverage enhancement mode. Therefore, in the embodiment, the regular mode is used as one of the working modes of the second type of node.

Of course, according to the different indicators, the working mode of the second node has other ways of dividing.

The working mode indication information of the second node that is prohibited from accessing is used to indicate the prohibited access of the second node in which working modes.

The second node has multiple types of services, such as a voice type or a network data type. Some of the first nodes only support the access of the service type of the one or more types of services. Therefore, the configuration information in the embodiment further includes: the service type indication information that is prohibited from being accessed. If the second node terminal A receives the configuration information, it can determine which current service type is the first node that is not allowed to access.

In this embodiment, the service type classification of the second node includes at least one of the following: classifying according to a data packet transmission rate; classifying according to a transmission delay of the data packet; classifying according to a packet transmission error rate; according to the data packet The packet length is classified; it is classified according to the transmission period of the data packet.

The type indication information of the supported second node is used to indicate to the second node which types of second nodes are allowed to access in the K third nodes. The supported mode information of the second node is used to indicate which operating modes are supported by the second node. The supported service type indication information is used to indicate which second node accesses are supported for processing.

In this way, the second node can determine which first nodes allow access by the first node according to the configuration information.

As shown in FIG. 2, the method described in this embodiment includes:

Step S110: Determine information content of the indication information according to the current load of the first node itself.

Step S121: When the current load is greater than the load threshold, send the indication information including the configuration information and/or the delay information to the second node, including the load level information.

The current load condition of the first node characterized by the current load. The current load can be represented by a current load value or a current load level. If the first node that sends the indication information is current, the load of the current node is relatively light, and the second node may be allowed to access. At this time, the first node may directly send its own load level information to the second type of point. Therefore, in the embodiment, the step S110 first compares the current load with the load threshold. If the current load is greater than the load threshold, it is determined that the indication information may only include the load level.

When the current load of the first node itself that sends the indication information is greater than the load threshold, the first node may not be able to allow access by the second node, in order to ensure that the second node accesses the network and implements load balancing, Then, in the step S110, it is further determined that the indication information includes load level information and configuration information. Therefore, as shown in FIG. 2, the method further includes:

Step S122: When the current load is not greater than the load threshold, send the indication information including the load level information to the second node.

Method Embodiment 2:

As shown in FIG. 3, this embodiment provides an access control method, where the method includes:

Step S210: The second node receives the indication information sent by the first node, where the indication information includes at least one of the following: load level information, configuration information of the K third nodes, and indicating that the second node delays sending the random Delay information of the access signaling; the load level information includes a current load level of the first node itself, and may be used to assist the second node to determine whether to access the first node; the K is not less than 1 The integer information; the configuration information may be used to assist the second node to determine whether to access other first nodes;

Step S220: determining whether the accessing the first node determines whether to access the first node or the third node according to the indication information;

The second node belongs to a second type of node, and the first node and the third node belong to a second node.

The access control method in this embodiment may be applied to the second node. The second node may comprise one of the following types of nodes:

The second node of the person to the person H2H;

The second node of the machine to the machine M2M;

Vehicle to the second node of the vehicle V2V;

Device to the second node of device D2D.

In this embodiment, the second node receives the indication information from the first node, and determines, according to the indication information, whether to access the first node or the third node that sends the indication information according to the step S210.

For example, the step S220 may include:

The first specified load level in the embodiment may be configured by the first node, or may be configured in the second node by default according to a communication standard. And if the first specified load level is configured by the first node, the second node further includes receiving the first specified load level from the first node. The first specified load level is a value that represents a lighter load of the first node. Generally, if the current load of the first node is lower than the first specified load level, if the second node accesses the first node, the first node is not overloaded, and the second The node can also have a higher success rate to access the first node.

Of course, the step S220 may further include:

The second specified load level may also be set by the first node, or may be set in the second node by default according to a communication standard. Generally, the second specified load level indicates that the load of the corresponding first node is heavy. If the second node is further accessed, the corresponding first node may be congested, which may result in poor communication quality or load imbalance. The problem.

If the load level is higher, indicating that the load amount is larger, generally the first specified load level is lower than the second specified load level, and if the load level is lower, indicating that the load amount is larger, the first A specified load level is higher than the second load level.

In this embodiment, when the second node determines that the current load of the first node is higher than the second specified load level, it selects from the K third nodes according to the configuration information. One or more nodes that are accessible to it access for service transmission.

For example, the selecting one or more of the third nodes from the K third nodes to perform access according to the configuration information and the selection policy includes:

One or more third nodes that allow access by the type of the second node are selected; the type herein may refer to the terminal type of the second node. For example, the terminal type of the second node is A; the one or more third nodes that select the type access of the second node are selected, and one or more third nodes accessed by the astronomy terminal type A are selected.

Selecting one or more third nodes that allow access to the working mode of the second node; The working mode of the two nodes is working mode B, where the selection allows one or more third nodes accessing the working mode of the second node to select one or more thirds that allow working mode B access. node.

One or more third nodes that allow access to the traffic type of the second node are selected. If the service type of the second node is the service type C, the selecting one or more third nodes that allow the service type of the second node to access includes: selecting one or more types that allow the service type C to access Three nodes.

The configuration information describes the information of the second node that is prohibited or allowed to access by the K third nodes, so the second node can easily select the second node that can be accessed according to the configuration information. And selecting, according to the selection policy, a third node that is most suitable for access by the second node.

As shown in FIG. 4, the method further includes:

Step S230: When there are multiple third nodes that are available for access by the second node, select a third node that is accessible to the second node to access according to the access policy.

The access policy may be configured in the second node, that is, in the second node, according to a communication standard, or may be received by the second node from the first node, for example, the two nodes are Received by the first node

The specific step S230 may include:

When accessing according to the foregoing access policy, when accessing one of the third nodes is unsuccessful, the access to the next third node is naturally performed, and the accessing to the second node may be performed until at least one of the The third node; this ensures as much as possible that the second node can access the communication network where the first node is located.

The step S220 may further include:

When the current load of the first node that sends the indication information is neither lower than the first specified load level nor higher than the second specified load, it is obvious that the load of the first node that sends the indication information is moderate, The second node chooses to access the first node without causing congestion of the first node, but also to access the third node in order to prevent the current load level of the first node from being higher than the second specified load level. . In this embodiment, the second node may determine whether to continue to access the first node according to the access policy, for example, randomly selecting a node that is accessible to the second node. The decision policy may include a random threshold, and the second node may randomly generate a random number, compare the random number with the random threshold, and compare and then determine whether to access the first node according to the comparison result.

When the indication information includes the load information and the delay information, the step S220 further includes:

And delaying access to the first node according to the delay indication information. The second node may also delay sending the random access signaling according to the delay indication information to delay access to the first node.

The step S210 in the embodiment may include: the second node in the first state receiving the indication information sent by the first node; wherein the first state includes: initial accessing the communication system State; transition from idle state to connected state.

Of course, the second node that is not in the first state, such as the idle state or the dormant state, may not perform the step of receiving the indication information for the purpose of saving power consumption.

It should be noted that the information content and the usage of the load level information, the configuration information, and the delay information in the embodiment of the present application can be referred to the first embodiment of the method, and are not repeated here.
