Description

Subnet fusion method and device, electronic equipment and storage medium

Technical Field

The present invention relates to the field of computer technologies, and in particular, to a subnet fusion method, device, electronic apparatus, and storage medium.

Background

An ad hoc network is a network without a fixed network infrastructure similar to a base station deployed, and nodes in the ad hoc network may cause an original network to be split into two or more sub-networks due to various reasons (for example, the nodes are turned off or the nodes are moved to a remote place, etc.), so that in order to ensure the service performability and reduce the interference of communication between the sub-networks, the process of merging the sub-networks needs to be completed, and the network integrity is restored.

The subnet fusion process generally includes the following steps: (1) a node to be fused discovers a new subnet; (2) Broadcasting new subnet information and determining that the opportunity leaves the atomic network; (3) merging into the new subnet. The existing node to be fused generally adopts a layer-by-layer off-network mode: and sending the new subnet information to inform surrounding neighbor nodes and then off-network, searching the new subnet after the neighbor nodes receive the new subnet information, and sending the new subnet information to inform the surrounding neighbor nodes and then off-network after determining that the new subnet is searched. Secondly, when the existing Node to be fused accesses a new subnet, an access request needs to be sent to the accessed Node, after the access request is synchronized with the accessed Node, the Node to be fused sends a signaling message to a main control Node, the main control Node judges whether the Node can be accessed or not, if so, a Node identity (Node Identity Document, node ID) is allocated to the Node to be fused, and then the main control Node sends a signaling to the Node to be fused to inform that the Node to be fused is successful in network access.

However, the existing subnet fusion process takes longer time, which has a certain influence on the service recovery time of the mobile ad hoc network.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Example 1

Fig. 1 is a flowchart of a subnet integration method provided in the first embodiment of the present invention, where the present embodiment is applicable to a case where a node to be integrated accesses a new subnet, the method may be performed by a subnet integration device, the subnet integration device may be implemented in a form of hardware and/or software, the subnet integration device may be configured in the node to be integrated, and the node to be integrated may be an electronic device (for example, a terminal or a server) with a data processing function. As shown in fig. 1, the method includes:

Step 110, broadcasting a new subnet message to other nodes in the atomic network after receiving the fusion instruction about the new subnet in the operation process of the nodes to be fused.

In this embodiment, the node to be fused may be a network node waiting to be fused with the new subnet. In the operation process of the node to be fused, if the node to be fused receives the fusion instruction about the new subnet, a new subnet message, such as a frequency point of the new subnet, a Physical Cell Id (PCI) and the like, can be broadcast to all other nodes in the subnet (i.e., the atomic network) where the node to be fused is located.

In a specific embodiment, the fusion indication about the new subnet may be a system message of the new subnet received by the node to be fused, where the system message includes information instructing the node to be fused to access the new subnet, and the specific fusion indication may be preset according to the actual situation, which is not limited in this embodiment.

And 120, after determining that surrounding neighbor nodes of nodes to be fused in the atomic network receive the new subnet message, leaving the atomic network and receiving the full-network node information corresponding to the new subnet.

In this embodiment, after the node to be converged broadcasts a new subnet message to all other nodes in the atomic network, if acknowledgement information fed back by surrounding neighboring nodes is received, or a new subnet message broadcast by the surrounding neighboring nodes is received, it may be determined that the surrounding neighboring nodes receive the new subnet message.

After determining that the surrounding neighboring nodes receive the new subnet message, the node to be converged can leave the atomic network, try to search the new subnet, and then receive the node information of the whole network corresponding to the new subnet.

If the new subnet searched by the node to be fused is a network with the same frequency and the same PCI as the atomic network, and the node in the atomic network is searched in the new subnet, the new subnet is ignored, and other new subnets are searched next.

And 130, determining a target access mode matched with the node to be fused according to the node information of the whole network, and fusing the node to be fused to a new subnet according to the target access mode.

In this embodiment, optionally, after the node to be fused receives the node information of the whole network of the new subnet, it may be detected whether the node information of the node to be fused is included in the node information of the whole network, and if not, it is determined that the target access mode is a normal access mode; if so, determining the target access mode as a simplified access mode.

In this embodiment, if the target access mode is the normal access mode, the node to be fused may perform information interaction with the accessed node and the master control node in the new subnet, so as to complete the fusion process of the node to be fused and the new subnet. If the target access mode is a simplified access mode, the node to be fused can finish the fusion process of the node to be fused and the new subnet only by carrying out information interaction with the accessed node in the new subnet.

Compared with the prior art that the nodes to be fused adopt a layer-by-layer off-network mode, the node to be fused in the embodiment can shorten the off-network time of the nodes and improve the off-network efficiency by broadcasting new subnet messages to all other nodes in the atomic network; secondly, compared with the conventional access mode in the prior art, the method and the system provide two access modes suitable for different nodes by analyzing the node information of the whole network, so that the time consumption of the integration of the subnets can be reduced, and the integration efficiency of the subnets and the service recovery efficiency of the mobile self-organizing network are improved.

According to the technical scheme provided by the embodiment of the invention, after the fusion instruction about the new subnet is received in the operation process of the node to be fused, the new subnet message is broadcast to other nodes in the atomic network; after determining that surrounding neighbor nodes of nodes to be fused in the atomic network receive the new subnet information, leaving the atomic network and receiving the whole network node information corresponding to the new subnet; and determining a target access mode matched with the node to be converged according to the node information of the whole network, and converging the target access mode to a new subnet according to the technical means of the target access mode, so that the convergence efficiency of the subnet and the service recovery efficiency of the mobile self-organizing network can be improved.

Example two

Fig. 2 is a flowchart of a subnet fusion method according to a second embodiment of the present invention, where the relationship between the present embodiment and the above embodiment is to add technical features of an access mode of a node to be fused for a new subnet. As shown in fig. 2, the method includes:

step 201, broadcasting a new subnet message to other nodes in the atomic network after receiving a fusion instruction about the new subnet in the operation process of the nodes to be fused.

Step 202, after determining that neighboring nodes around the node to be fused in the atomic network receive the new subnet message, leaving the atomic network and receiving the full-network node information corresponding to the new subnet.

In a specific embodiment, the node information of the whole network may include information such as an internet protocol (Internet Protocol, IP) address and a product Sequence Number (SN) corresponding to each node in the new subnet, as shown in table 1.

Step 203, judging whether the node information of the whole network includes node information of nodes to be fused; if yes, go to step 204-205, if not, go to step 206-208.

In this embodiment, optionally, according to the node name of the node to be fused, whether the node information of the node to be fused is included in the whole network node information may be determined.

TABLE 1

Step 204, determining an accessed node according to the whole network node information, completing a synchronization process with the accessed node, and then sending a first signaling message to the accessed node; the first signaling message includes node information of the nodes to be fused, node information of the accessed nodes and access types.

In this embodiment, if the Node information of the Node to be fused is included in the Node information of the whole network, it may be determined that other nodes already exist in the atomic network and access to the new subnet, and the master control Node in the new subnet has allocated a Node identity Node ID to the Node to be fused.

In this case, the accessed Node may be determined according to the Node ID included in the Node information of the whole network, and a synchronization procedure (including clock synchronization, frequency synchronization, etc.) with the accessed Node is completed, and then the first signaling message is transmitted to the accessed Node. The first signaling message includes node information of the nodes to be fused, node information of the accessed nodes and access type (i.e. simplifying access mode).

Step 205, receiving a second signaling message fed back by the access node for the first signaling message, and broadcasting the node information of the whole network to other nodes in the atomic network.

In this embodiment, after receiving the first signaling message sent by the Node to be fused, the accessed Node does not need to forward the first signaling message to the master control Node, but directly feeds back a second signaling message to the Node to be fused, where the second signaling message includes a Node ID allocated by the master control Node to the Node to be fused.

After the converged node receives the second signaling message, the success of the access to the new subnet can be determined, and the whole network node information is broadcasted to other nodes in the atomic network, so that the other nodes can perform the convergence to the new subnet according to the whole network node information.

And 206, determining an accessed node according to the whole network node information, and completing the synchronization process with the accessed node.

In this embodiment, if the Node information of the Node to be fused is not included in the Node information of the whole network, the accessed Node may be determined according to the Node ID included in the Node information of the whole network, and the synchronization process (including clock synchronization, frequency synchronization, etc.) with the accessed Node may be completed

Step 207, sending a third signaling message to an accessed node, and forwarding the third signaling message to a master control node in a new subnet by the accessed node; the third signaling message comprises node information of the nodes to be fused, node information of the accessed nodes, access types and a node information list corresponding to the atomic network.

In this step, specifically, the third signaling message may include node information of the node to be fused, node information of the node to be accessed, an access type (i.e. a normal access mode), and a node information list corresponding to the atomic network, as shown in table 2.

TABLE 2

new_accessing_node_info	Node letter of node to be fusedRest
		accessed_node_info	Node information of accessed node
access_type	Access type (normal access mode)
		old_subnet_node_list	Atomic network node information list

Step 208, receiving the fourth signaling message sent by the accessed node, and broadcasting the node information of the whole network to other nodes in the atomic network.

In this embodiment, the fourth signaling message is generated by the master node and is sent to the accessed node, where the fourth signaling message includes a node identifier allocated by the master node to the node to be fused, node information of the node to be fused, and node information of the accessed node.

After receiving the third signaling message, the master control Node can determine whether the Node to be fused can access the new subnet, if so, the Node to be fused is allocated with a Node ID according to a preset Node ID allocation criterion, meanwhile, other nodes in the atomic network are allocated with a new Node ID, and then a fourth signaling message is generated according to the Node ID of the Node to be fused, the Node information of the Node to be fused and the Node information of the accessed Node, and is sent to the accessed Node, and the accessed Node sends the fourth signaling message to the Node to be fused. Meanwhile, the master control Node can update the Node information of the whole network according to the Node ID allocated by the Node to be fused and the Node IDs allocated by other nodes in the atomic network.

In this step, after the node to be fused receives the fourth signaling message, it can determine that the access to the new subnet is successful, and broadcast the node information of the whole network to other nodes in the atomic network, so that the other nodes fuse the new subnet according to the node information of the whole network.

Step 209, initializing the metric value of the node to be fused, so that the master control node determines the access condition of the node to be fused for the new subnet according to the change condition of the metric value.

In this embodiment, after the node to be fused is accessed to the new subnet, the meta value may be initialized, and when the master control node in the new subnet detects that the meta value of the node to be fused is changed, it may be determined that the node to be fused is successfully accessed to the new subnet. Specifically, in the initializing process of the metric value, the metric value may be set to any invalid value (for example, 255), and the specific value may be preset according to the actual situation, which is not limited in this embodiment.

According to the technical scheme provided by the embodiment of the invention, after a fusion instruction about a new subnet is received in the operation process of a node to be fused, a new subnet message is broadcast to other nodes in an atomic network, after the surrounding neighbor nodes of the node to be fused in the atomic network are determined to receive the new subnet message, the node information of the whole network corresponding to the new subnet is left from the atomic network and received, whether the node information of the node to be fused is included in the whole network is judged, if yes, an accessed node is determined according to the node information of the whole network, a synchronization process with the accessed node is completed, then a first signaling message is sent to the accessed node, a second signaling message fed back by the accessed node aiming at the first signaling message is received, and the node information of the whole network is broadcast to other nodes in the atomic network; if not, determining the accessed node according to the node information of the whole network, completing the synchronization process with the accessed node, sending a third signaling message to the accessed node, forwarding the third signaling message to a main control node in a new subnet by the accessed node, receiving a fourth signaling message sent by the accessed node, and finally initializing the metric value of the node to be fused, thereby improving the fusion efficiency of the subnet and the service recovery efficiency of the mobile ad hoc network.

Example III

Fig. 3 is a flowchart of a subnet integration method provided in the third embodiment of the present invention, where the present embodiment is applicable to a case where a node to be integrated accesses a new subnet, the method may be performed by a master node in the new subnet, and the master node may be an electronic device (for example, a terminal or a server) with a data processing function. As shown in fig. 3, the method includes:

step 310, receiving a third signaling message sent by the accessed node, where the third signaling message includes node information of the node to be fused, node information of the accessed node, an access type and a node information list corresponding to the atomic network.

And 320, distributing corresponding node identity identifiers for the nodes to be fused and other nodes in the atomic network according to the third signaling message.

And 330, generating a fourth signaling message according to the third signaling message and node identities of the nodes to be fused and other nodes in the atomic network, which correspond to each other.

Step 340, the fourth signaling message is sent to the accessed node, and the information of the all network nodes of the subnet where the main control node is located is updated, and then the information of the all network nodes is broadcasted.

In this step, node IDs allocated to the nodes to be fused and Node IDs allocated to other nodes in the atomic network may be added to the Node information of the whole network, so as to complete updating of the Node information of the whole network.

According to the technical scheme provided by the embodiment of the invention, the corresponding node identity identifiers are distributed to the node to be fused and other nodes in the atomic network according to the third signaling message by receiving the third signaling message sent by the accessed node, the fourth signaling message is generated according to the third signaling message and the node identity identifiers respectively corresponding to the node to be fused and other nodes in the atomic network, the fourth signaling message is sent to the accessed node, the information of all-network nodes of the sub-network where the main control node is located is updated, and then the information of all-network nodes is broadcasted, so that the fusion efficiency of the sub-network and the service recovery efficiency of the mobile self-organizing network can be improved.

Example IV

Fig. 4a is a flowchart of a subnet integration method according to a fourth embodiment of the present invention, where the method may be performed by an accessed node in a new subnet, where the accessed node may be an electronic device (e.g., a terminal or a server) with a data processing function. As shown in fig. 4a, the method comprises:

step 410, receiving a signaling message sent by a node to be converged, and identifying the signaling message.

In this embodiment, the recognition result of the signaling message may be determined according to specific information included in the signaling message. Specifically, if the signaling message sent by the node to be fused includes node information of the node to be fused, node information of the accessed node and an access type, the signaling message can be determined to be a first signaling message; if the signaling message sent by the node to be fused comprises node information of the node to be fused, node information of the accessed node, an access type and a node information list corresponding to the atomic network, the signaling message can be determined to be a third signaling message.

Step 420, determining a signaling processing mode according to the identification result, and determining a target signaling message according to the signaling processing mode.

And 430, sending the target signaling message to the node to be converged so that the node to be converged determines the access condition of the new subnet according to the target signaling message.

In this embodiment, if the signaling message received by the access node is the first signaling message, the corresponding second signaling message may be used as the target signaling message, and the target signaling message may be sent to the node to be fused; if the signaling message received by the access node is the third signaling message, the third signaling message may be sent to the master control node, and the fourth signaling message fed back by the master control node is used as the target signaling message, and the target signaling message is sent to the node to be fused.

According to the technical scheme provided by the embodiment of the invention, the signaling message is identified by receiving the signaling message sent by the node to be fused, the signaling processing mode is determined according to the identification result, the target signaling message is determined according to the signaling processing mode, and the target signaling message is sent to the node to be fused, so that the node to be fused determines the access condition of the new subnet according to the target signaling message, and the fusion efficiency of the subnet and the service recovery efficiency of the mobile self-organizing network can be improved.

In order to better introduce the technical solution provided by the embodiments of the present invention, the embodiments of the present invention may refer to the following embodiments:

in a specific embodiment, fig. 4B may be a schematic structural diagram of a subnet, and as shown in fig. 4B, it is assumed that the existing subnet a and the subnet B, and the node 5 in the subnet a is a master node. When node 3 in subnet B receives the convergence indication for subnet a:

step 1: the node 3 broadcasts a message of the subnet A to all other nodes in the subnet B, after the surrounding adjacent nodes (namely the node 4 and the node 5) of the node 3 are determined to be successfully received, the node 3 leaves the network and searches the subnet A, and then the whole network node information of the subnet A is received;

Step 2: after the node 3 receives the whole network node information (as shown in table 3) of the subnet A, determining that the node information of the node 3 is not included in the whole network node information, and considering the current access mode as a normal access mode;

TABLE 4 Table 4

Step 5: the master control node (node 5) in the subnet a replies a fourth signaling message to the node 6 after receiving the third signaling message. The fourth signaling message includes the Node Id (assumed to be 8) allocated to Node 3 by the master Node. In addition, the master Node allocates Node ids (assumed to be 9 and 10) to nodes 4 and 5 in the subnet B, thereby obtaining updated Node information of the entire network, as shown in table 5;

TABLE 5

Step 6: node 6 forwards the fourth signaling message to node 3 after receiving the fourth signaling message, and considers that node 3 is successful in network access;

step 7: after receiving the fourth signaling message, the node 3 considers that network access is successful, and broadcasts the node information of the whole network after updating the metric value, as shown in table 6.

In another embodiment, it is assumed that after the node 4 in the subnet B receives the full-network node information sent by the node 3, it is determined that the full-network node information includes the node information of the node 4, so that the node 4 may adopt a simplified access mode:

step 8: after the synchronization between the Node 4 and the Node 3 is completed, the Node 4 sends a first signaling message (as shown in table 7) to the Node 3, and the Node 3 replies a second signaling message (including the Node Id of the Node 4) to the Node 4;
