As shown in FIG. 2, the method for self-organization of the network includes:

In 210, the first node selects at least one second node among the candidate nodes according to a preset condition.

In 220, the first node establishes a connection with the plurality of second nodes by sending a connection establishment request to the at least one second node.

Specifically, the first node selects at least one second node among the candidate nodes based on the preset condition, and sends a connection establishment request to the at least one second node, respectively, to establish a connection with the at least one second node. The candidate node includes a plurality of nodes. After establishing the connection between the first node and the at least one second node, the data may be transmitted to the core network or the data transmitted by the core network may be obtained by any one or several second nodes of the at least one second node.

Optionally, the first node establishes a connection with the multiple second nodes, including: establishing, by the first node, the connection between the multiple second nodes based on the Uu interface.

Optionally, the preset condition includes: the signal measurement result of the candidate node is higher than a preset threshold.

The preset threshold may be configured by the network device for the first node, or the preset threshold is that the network device is previously agreed with the first node and pre-stored in the first node.

The first node may measure the RSRP and/or the RSRQ of the surrounding node in the process of searching for the second node, and use the node with the RSRP and/or the RSRQ higher than the corresponding preset threshold as the candidate node, thereby At least one second node is selected among the candidate nodes, and a connection establishment request is sent to the at least one second node.

For example, the first node measures the RSRP of each node to obtain the RSRP measurement result of each node, and uses a node whose RSRP measurement result is higher than the reference signal receiving power threshold as a candidate node.

For another example, the first node measures the RSRQ of each node to obtain a measurement result of the RSRQ of each node, and uses a node whose RSRQ measurement result is higher than a reference signal reception quality threshold as a candidate node.

For another example, the first node measures the RSRP and the RSRQ of each node, and the node whose RSRP measurement result is higher than the reference signal received power threshold and whose RSRQ measurement result is higher than the reference signal receiving quality threshold is used as the candidate node.

In the cell selection process, the signal received power can be expressed as:

S _rxlev =Q _rxlevmeas –(Q _rxlevmin +Q _{rxlevminoffset} )-P _compensation ;

Where S _rxlev >0. Q _rxlevmeas is the reference signal received power RSRP of the candidate cell; Q _rxlevmin and Q _{rxlevminoffset} are the minimum reception levels of the cell resident configured in the System Information Block (SIB), only when the first node resides Q _{rxlevminoffset} is used in the virtual public land mobile network (VPLMN) cell; P _compensation =Max(P _EMAX -P _UMAX , 0), P _EMAX is the maximum usable uplink of the first node. Transmit power, P _UMAX is the maximum RF output power of the first node, in dB.

The signal reception quality in the cell selection process can be expressed as:

S _qual =Q _qualmeas –(Q _qualmin +Q _{qualminoffset} )-P _compensation ;

Where S _qual >0. _Q qualmeas RSRQ reference signal received quality of the candidate _cells; Q qualmin and _Q qualminoffset minimum reception quality value is camped cell, only when the first node resides in the cell used VPLMN _Q rxlevminoffset; P _compensation = Max ( P _EMAX -P _UMAX , 0), P _EMAX is the maximum available transmit power of the first node, and P _UMAX is the maximum RF output power of the first node, in dB.

Therefore, the reference signal received power threshold can be expressed as Q _rxlevmeas =S _rxlev +(Q _rxlevmin +Q _{rxlevminoffset} )+P _compensation , that is, the reference signal received power threshold can include multiple components; the reference signal receiving quality threshold can be Expressed as S _qual =Q _qualmeas -(Q _qualmin +Q _{qualminoffset} )-P _compensation , that is, the reference signal reception quality threshold may include a plurality of components. The value of each component may be configured by the network device or pre-existing in the first node.

Optionally, in 220, the first node establishes a connection with the at least one second node by sending a connection establishment request to the at least one second node, where: the first node passes to the at least one second node. The one or more second nodes send a Radio Resource Control (RRC) connection request message to establish a connection with the one or more second nodes.

For example, the first node sends an RRC connection setup request message to a second node, and establishes a connection of the master node, where the second node establishes a connection with the second node, and the second node serves as the first node. The primary node of a node.

Optionally, in 220, the first node establishes a connection with the at least one second node by sending a connection establishment request to the at least one second node, where: the first node passes to the at least one second node. The one or more second nodes send an RRC reconfiguration complete message to establish a connection with the one or more second nodes.

For example, the first node sends an RRC reconfiguration complete message to a second node, and establishes a connection of the secondary node, where the second node establishes a connection with the second node and the second node serves as the first node. A secondary node of a node.

Optionally, when the first node does not establish a connection, the level of the first node is configured to be the lowest level.

In the embodiment of the present application, the level of each node may reflect the number of links between each node and the anchor node, and the higher the level of one node indicates that the number of hops between the node and the anchor node is less.

Alternatively, the information of the level of each node may be represented by an information field. For example, if the information field consists of 8 bits, then a total of 256 levels can be represented. It is assumed that the smaller the value on the information field, the higher the level of the node, that is, the smaller the number of hops relative to the anchor node. Then, if the value on the information field is 0, it can indicate that the hop count of the node relative to the anchor node is 1, that is, the direct wireless connection between the node and the anchor node; if the value on the information field is 255 When it is, it can be said that the hop count of the node relative to the anchor node is 256. Or, if the value on the information field is 0, it indicates that the node is an anchor node; if the value on the information field is 255, it indicates that the hop count of the node relative to the anchor node is 255.

The anchor node here may also be referred to as a donor node, and the anchor node may directly make a wired connection with the core network.

Connected nodes.

It should be understood that when one node is a child of another node, correspondingly, the other node is the parent of the node. A child node usually requests a connection with a parent node by sending a connection establishment request to the parent node, and the parent node establishes a connection with the child node after receiving the connection establishment request sent by the child node.

In other words, if the first node is assumed to be the base station, that is, the role of the base station, and the other node is assumed to be the terminal device, that is, as the terminal device, after the connection establishment request is sent to the first node and the connection is established, the The other node is the child node of the first node, the first node is the parent node of the other node; if another node is assumed to be the base station, it is the role of the base station, and the first node is assumed to be the terminal device That is, as the role of the terminal device, after sending a connection establishment request to the other node and establishing a connection, the first node is a child node of the other node, and the other node is a parent node of the first node.

In one case, when the first node sends a connection establishment request to the at least one second node, the first node is not connected to the child node.

At this time, since the first node is not connected to any child node, the first node may directly send a connection establishment request to the second node to request to establish a connection with the second node, so that the second node becomes the parent node of the first node. .

In another case, when the first node sends a connection establishment request to the at least one second node, the first node is connected to the child node.

At this time, since the first node is connected to the child node, in order to avoid affecting the child node of the first node, before the first node sends a connection establishment request to the second node, the first node needs to be disconnected from the first node. The connection between all child nodes. Then, a connection establishment request is sent to the second node to request to establish a connection with the second node, so that the second node becomes the parent node of the first node. Alternatively, the first node may not disconnect from all its child nodes, but the level of the at least one second node must be higher than the level of the first node.

Optionally, the method further includes: the first node receiving an RRC reconfiguration message sent by the third node, where the RRC reconfiguration message indicates that the first node establishes a connection with the at least one second node.

Wherein, if a node such as node 4 is not connected to other child nodes, the child node connected under node 2 includes only node 4.

Optionally, if there is still one node 7, and both node 1 and node 7 are child nodes connected under node 0, and the level of node 7 is lower than the level of node 1, the candidate node also does not include node 7.

For example, the first node may select a node in a 5G system as a master node and select a secondary node among the remaining nodes; or the first node may select a node in an LTE system as a master node, and in the remaining nodes. Select the secondary node.

Optionally, when the first node performs the selection of the secondary node, the first node may autonomously perform the selection of the secondary node; or the first node may also perform the secondary node according to the configuration of the primary node of the first node. Selecting, for example, the first node receives the first configuration information sent by the primary node of the first node, and performs selection of the secondary node according to the first configuration information. The first configuration information may indicate that the first node performs the selection of the secondary node, or the first configuration information may directly indicate the secondary node that the first node needs to select.

Optionally, the method further includes: after the first node establishes a connection with each second node, the first node reports the child node connected to the second node to the second node. The child node connected under the first node includes a child node of the first node and a child node connected under the child node of the first node, wherein the child node connected under any node includes any one of A child node of a node and a child node connected to a child node of the any node, the child node of the node being a node that establishes a connection by sending a connection establishment request to the any node.
