In the related art, the intelligent capability is mainly concentrated on a few intelligent network elements such as NWDAF, and is not suitable for a distributed communication network scenario. For a distributed communication network, a device capable of providing a certain intelligent capability needs to be screened from a plurality of capability providing devices, which results in complicated capability calling steps and low efficiency. Furthermore, the lack of uniform capability authentication may cause a deviation in the determined capability providing device, resulting in inaccurate capability invocation.
In view of one or more of the problems set forth above, exemplary embodiments of the present disclosure provide a capability invocation method. The method can be applied to various decentralized distributed communication network scenes. Illustratively, the method may be applied to a terminal ad hoc network, such as: D2D (Device-to-Device) communication networks, near domain intelligent networking, etc.; the method is also applicable to slice networks; the method may also be applied to a submerged network, for example: MEC (Mobile Edge Computing ), local UPF (User Plane Function, user plane function) network, etc.; the method can also be applied to a reduced network without deploying a centralized network intelligent lookup node (such as NRF (Network Repository Function, network storage network element), NWDAF, etc.).
It should be noted that, the present disclosure may build a blockchain network based on an original distributed communication network, use a node in the distributed communication network as a node in the blockchain network, and execute the capability calling method by any capability providing node in the blockchain network.
Fig. 1 shows a schematic flow of a capability calling method in the present exemplary embodiment, including the following steps S110 to S120:
Step S110, determining a target capacity block corresponding to capacity to be called in a public chain of a blockchain network, wherein the capacity to be called is the capacity requested to be called by a capacity demand node;
step S120, determining a target capability providing node according to the target capability block;
step S130, the calling of the to-be-called capability is initiated to the target capability providing node, and a capability calling result aiming at the to-be-called capability is fed back to the capability requirement node.
In the process, the capacity provided by each capacity providing node is stored in the form of the block chain, capacity calling is achieved based on the capacity blocks, screening and authentication are not needed from a plurality of capacity providing nodes one by one, accuracy and efficiency of capacity calling can be ensured, and capacity calling of the capacity providing nodes is more convenient and rapid. In addition, the capacity call of the capacity providing node is realized through the decentralization deployment, the centralized network intelligent searching capacity node is not required to be specially deployed, and the scene applicability is stronger.
It should be noted that, a capability requirement node in the present disclosure refers to a node that requests a specific intelligent capability, and may be a virtual node or an entity node. Illustratively, the capability requirement node may be a network node where a network element, base station, terminal, etc. may request intelligent capabilities. Capability providing nodes in this disclosure refer to nodes that may be used to provide specific intelligent capabilities, either virtual nodes or physical nodes. Illustratively, the capability providing node may be a node having intelligent capabilities, such as a network element, a base station, a terminal, etc.
At least one capability requirement node, at least one capability providing node may be included in the blockchain network. Each capability providing node may store up-to-date and complete public chain information to enable quick determination of a target capability block from the public chain. The capability invocation method shown in FIG. 1 may be performed by a capability providing node present in the blockchain network to assist a capability demand node in enabling invocation of a capability to be invoked.
Each step in fig. 1 is specifically described below.
Step S110, a target capacity block corresponding to the capacity to be called is determined in a public chain of the blockchain network, and the capacity to be called is the capacity requested to be called by the capacity demand node.
The capability to be invoked refers to a capability requested to be invoked by a capability requirement node, and taking the capability requirement node as a user terminal device as an example, the capability to be invoked may, for example, "determine whether the user terminal device is in a motion state", "acquire a motion trail of the user terminal device", and the like.
The target capability block may be a capability block of the public chain that matches the capability to be invoked. The public chain of the blockchain network is an intelligent capability blockchain capable of realizing intelligent capability inquiry and call, and can be discovered by all capability providing nodes in the blockchain network. The public chain can comprise a plurality of capability blocks, and different capability blocks can correspond to different intelligent capabilities, and the capability blocks of the public chain can consist of information such as block identification parameters, capability providing node parameters, capability input parameters, capability output parameters and the like. Further, the first blockchain may be a public chain.
As shown in fig. 2, a schematic diagram of a public chain of a blockchain network is provided, the public chain 200 may include a plurality of capability blocks, and each capability block may include information such as a block identifier 211, a capability providing node parameter 212, a capability input parameter 213, a capability output parameter 214, and the like. Taking the first intelligent block as an example, the "intelligent capability block 1" can be used to represent a block identifier; "capability providing node: a1, b1, c1″ may be used to represent capability providing node parameters, where a1, b1, c1 may be node identities such as node names, addresses, etc.; "input parameters: the x1, y1 and z 1' can be used for representing capability input parameters, and are mainly used for intelligent capability analysis, and parameters required by different types of analysis are different, and the intelligent capability is taken as an example of judging the motion state of the user terminal equipment, and the motion speed, motion track, time and other parameter information of the user terminal equipment can be taken as the capability input parameters; "output parameters: f1″ may be used to represent a capability output parameter, and taking the intelligent capability as an example of "determining the motion state of the user terminal device", the motion state of the user terminal device may be taken as the capability output parameter.
It should be noted that, the number of blocks included in the public chain of the blockchain network is only shown in fig. 2 by way of example, and in practical application, the number of blocks included in the public chain of the blockchain network may be any integer.
In order to distinguish from other capability providing nodes in the blockchain network, the capability providing node that performs the capability invocation method will be referred to as the current capability providing node hereinafter.
The above-mentioned determination of the target capability block corresponding to the capability to be invoked in the public chain of the blockchain network may be performed by interaction between the capability requirement node and the current capability providing node. The interaction between the capability requirement node and the current capability providing node will be described in detail below.
In an alternative embodiment, the determining, in the public chain of the blockchain network, the target capability block corresponding to the capability to be invoked in step S110 may be implemented in the following manner: acquiring a capability calling request initiated by a capability demand node aiming at a capability to be called, wherein the capability calling request comprises block identification information; and determining a target capacity block corresponding to the capacity to be called in a public chain of the block chain network according to the block identification information.
In the above process, the current capability providing node determines a target capability block corresponding to the intelligent capability required to be invoked by the capability requirement node by interacting with the capability requirement node, so as to assist the capability requirement node to complete the capability invocation.
In an alternative embodiment, before acquiring the capability calling request initiated by the capability requirement node for the capability to be called, the capability requirement node may also send, to the capability requirement node, block capability information corresponding to a public chain of the block chain network in response to the capability query request initiated by the capability requirement node for the capability to be called, so that the capability requirement node searches for block identification information matched with the capability to be called from the block capability information, and generates the capability calling request based on the block identification information.
The capability query request refers to request information initiated by a capability requirement node, and the capability requirement node can be used for acquiring the block capability information corresponding to the public chain from any capability providing node in the block chain network. Optionally, to further reduce the communication overhead of the capability requirement node, the capability requirement node may initiate a capability query request to the capability providing node closest to itself. Optionally, to facilitate management and maintenance of the node, the capability requirement node may also initiate a capability query request to the capability providing node having the agreed relation. The capability requirement node specifically initiates a capability query request to which capability providing node, and may be configured in advance at the capability requirement node, which is not specifically limited herein.
The block identification information refers to identification information for distinguishing different blocks, and may be information such as a number of a block, a capability name, and the like.
The block capability information refers to intelligent capability information corresponding to each capability block in a public chain of the block chain network. After receiving the block capability information sent by the current capability providing node, the capability requirement node can search the block identification information matched with the capability to be invoked from the block capability information, and generate a capability invoking request based on the block identification information. Specifically, the capability requirement node can search the block identification information matched with the capability to be called from the block capability information through a keyword query method, a problem matching method and the like.
In the above process, by performing the capability query operation by the capability requirement node, the processing pressure of the current capability providing node can be reduced to some extent.
In addition, in an alternative embodiment, the determining, in the public chain of the blockchain network, the target capability block corresponding to the capability to be invoked in the step S110 may be implemented in the following manner: responding to a capability inquiry request initiated by a capability to be called by a capability demand node, determining a capability block corresponding to the capability to be called in a public chain of a blockchain network, and taking the capability block corresponding to the capability to be called as a target capability block.
In the process, the current capability providing node is used for providing the capability query service for the current capability demand node, so that communication overhead generated by interaction between the current capability calling node and the current capability demand node can be reduced to a certain extent.
The above procedure provides two ways of interacting to determine the target capacity block. It should be noted that, in the practical application process, the adopted interaction mode may be selected according to the communication overhead requirement and the performance requirement of the processor.
With continued reference to fig. 1, in step S120, a target capability providing node is determined according to the target capability block.
The target capability providing node is a node capable of providing a function to be invoked.
It should be noted that, in a public chain of a blockchain network, one capability block may correspond to one or more capability providing nodes.
If only one capability providing node corresponds to the target capability block, the capability providing node in the target capability block can be used as the target capability providing node.
Because of the wide variety of capability providing nodes included in a blockchain network, there may be multiple capability providing nodes that may each provide a particular intelligent capability, and thus a capability block may correspond to multiple capability providing nodes.
If the target capability block corresponds to a plurality of candidate capability providing nodes, one target capability providing node needs to be selected from the plurality of candidate capability providing nodes. In an alternative embodiment, the determining the target capability providing node according to the target capability block in step S120 may be further implemented by: acquiring capability evaluation data of candidate capability providing nodes from private chains corresponding to the target capability blocks; a target capability providing node is determined from the candidate capability providing nodes based on the capability assessment data of the candidate capability providing nodes.
After the capability demand node calls the capability to be called, call evaluation data can be generated to serve as a reference basis for subsequent call. The private chain may be a blockchain formed by historical capability assessment data generated by the respective capability requirement nodes, and a private chain may be created in advance for each capability block. One or more capability assessment blocks may be included in the private chain, specifically created by the actual capability invocation case, without limitation. The private chain can share the block information according to the grouping condition or the appointed relation of the nodes in the network.
For example, fig. 3 provides a schematic diagram of a private chain structure corresponding to a capability block, taking a private chain 300 corresponding to an intelligent capability block 2 as an example, the private chain 300 includes a block 301 and a block 302. Wherein, the block identifier corresponding to the block 301 is "intelligent evaluation block 21", which indicates that the evaluation of the capability calling node a to the capability providing node a2 is "good"; the block corresponding to block 302 is identified as "intelligent evaluation block 22" indicating that the capability call node B evaluates to "bad" for the capability providing node B2. It should be noted that, the number of blocks included in the private chain corresponding to the capability block is only illustrated in fig. 3 by way of example, and in practical application, the number of blocks included in the private chain corresponding to the capability block may be any integer, where the capability calling node refers to a capability requirement node that has called a capability provided by a certain capability providing node in the network.
It should be noted that, the current capability providing node belongs to one capability providing node in the blockchain network, there may be two cases of the target capability providing node determined according to the target capability block in step S120: the target capability providing node is just the current capability providing node; and secondly, the target capability providing node is not the current capability providing node.
With continued reference to fig. 1, step S130, a call for the capability to be invoked is initiated to the target capability providing node, and a capability call result for the capability to be invoked is fed back to the capability demand node.
If the target capability providing node is exactly the current capability providing node, the current capability providing node can directly provide corresponding intelligent capability for the capability requirement node initiating the capability calling request, and the capability calling result for the capability to be called is fed back to the capability requirement node.
If the target capability providing node is not the current capability providing node, the current capability providing node can initiate the call of the capability to be invoked to the target capability providing node, and the target capability providing node responds to the call of the capability to be invoked initiated by the current capability providing node to execute the corresponding intelligent capability, so that the corresponding intelligent capability is provided for the capability requirement node initiating the capability call request. Then, the current capability providing node may feed back a capability calling result for the capability to be called to the capability requirement node that initiated the capability calling request.
In the above process, based on the capability evaluation data of the second blockchain, the target capability providing node which better accords with the self condition can be determined for the capability requirement node, so that the suitability of capability calling is improved, and the capability calling requirement of the capability requirement node can be met better.
After feeding back the capability calling result for the capability to be called to the capability demand node, the current capability providing node can be used as the capability calling node, and can perform satisfaction evaluation analysis on the calling result corresponding to the capability to be called to obtain capability evaluation data corresponding to the capability to be called. The capability assessment data may be an assessment type of data or a hierarchical type of data, such as "good", "bad", etc.
When the capability evaluation data corresponding to the capability to be invoked is obtained, the private chain corresponding to the target capability block can be updated in the following two ways.
In an alternative embodiment, the capability requirement node may upload the capability evaluation data corresponding to the capability to be invoked to the private chain corresponding to the target capability block, and update the block information of the private chain corresponding to the target capability block, so that the current capability providing node may obtain the latest capability evaluation data, so as to serve as a reference basis for discovery and selection of the subsequent target capability providing node.
In an optional implementation manner, the current capability providing node may further obtain capability evaluation data corresponding to a capability calling result of the capability to be called; and updating the private chain corresponding to the target capacity block according to the capacity evaluation data corresponding to the capacity calling result of the capacity to be called.
The capability requirement node may send capability evaluation data corresponding to the capability to be invoked to the current capability providing node. The current capability providing node feeds back a capability calling result aiming at the capability to be called to the capability demand node, and then the capability evaluation data generated by the capability demand node aiming at the capability calling result can be obtained; and uploading the capability evaluation data generated by the capability demand node aiming at the capability calling result to the private chain corresponding to the target capability block, and updating the block information in the private chain corresponding to the target capability block so as to serve as a reference basis for the discovery and selection of the subsequent target capability providing node.
In the above process, the block information of the private chain corresponding to the target capacity block is updated, so that the current capacity providing node can better match the capacity calling requirement of the capacity demand node when the target capacity providing node is determined for the capacity demand node later.
It should be noted that the above processes are all performed in the case where the target capability block exists in the public chain based on the blockchain network.
If there is no target capability block in the public chain of the blockchain network, in an alternative embodiment, the target capability block may be obtained by: creating a new capability block for the capability to be invoked in a public chain of the blockchain network; broadcasting the new capability block in the blockchain network so that a capability providing node for providing the capability to be invoked in the blockchain network adds own node information into the new capability block; if the new capacity block is updated, the new capacity block is taken as a target capacity block.
The new capability block refers to a null block corresponding to the capability to be invoked, i.e. the capability providing node parameter is null, as shown in block 401 in fig. 4. After creating the new capability block, the new capability block may be broadcasted in the network, so that the capability providing node in the network, which is capable of providing the capability to be invoked, signs the new capability block, and adds the capability providing node to the new capability block, so that the block information of the new capability block is updated. After the current capability providing node detects that the new capability block is updated, the capability block can be used as a target capability block, so that the capability requirement node is assisted to complete the calling of the capability to be called.
In the process, the new capacity block is created, so that the dynamic expansion of the intelligent capacity in the block chain network is triggered, the applicability of capacity calling can be enhanced, and the development cost is reduced.
If the capability requirement node does not find the block identification information matched with the capability to be invoked from the block capability information, the capability requirement node indicates that the target capability block does not exist in the common chain of the current blockchain network. At this time, the capability requirement node may send a block creation request for the capability to be invoked to the current capability providing node. The block creation request, which refers to a request to create a new capability block on the first blockchain, may include related data information of the capability to be invoked. In an alternative embodiment, the creation of the new capability block for the capability to be invoked in the public chain of the blockchain network may be implemented by: and responding to a block creation request initiated by the capability requirement node, and creating a new capability block aiming at the capability to be invoked in a public chain of the blockchain network, wherein the block creation request is initiated when the capability requirement node does not find the block identification information matched with the capability to be invoked from the block capability information.
In the above process, through the interaction between the capability requirement node and the current capability providing node, a new capability block is created to trigger the dynamic update of the public chain of the blockchain network, so as to provide a callable target capability block for the current capability requirement node in real time.
FIG. 5 provides a capability call flow diagram for querying a target capability block by a capability requirement node, which may be performed by a capability providing node closest to the capability requirement node, and which may specifically include the steps of:
step S501, responding to a capability inquiry request initiated by a capability demand node aiming at capability to be called, and sending block capability information corresponding to a public chain of a block chain network to the capability demand node so that the capability demand node searches block identification information matched with the capability to be called from the block capability information;
step S502, judging whether a target capacity block exists in a public chain of the block chain network, if yes, executing step S503 and step S504, and if not, executing step S505;
step S503, responding to a block creation request initiated by a capability demand node, and creating a new capability block aiming at the capability to be invoked in a public chain of a block chain network;
Step S504, broadcasting the new capability block in the blockchain network so that the capability providing node providing the capability to be invoked in the blockchain network adds own node information into the new capability block; if the new capacity block is updated, the new capacity block is used as a target capacity block;
step S505, a capability calling request initiated by a capability demand node aiming at a capability to be called is obtained, wherein the capability calling request contains block identification information; determining a target capacity block corresponding to the capacity to be called in a public chain of a block chain network according to the block identification information;
step S506, acquiring capability evaluation data of the candidate capability providing node from the private chain corresponding to the target capability block; determining a target capability providing node from the candidate capability providing nodes based on the capability assessment data of the candidate capability providing nodes;
step S507, the calling of the capacity to be called is initiated to the target capacity providing node, and a capacity calling result aiming at the capacity to be called is fed back to the capacity demand node.
It should be noted that, in step S502, when determining whether the target capability block exists in the public chain of the blockchain network, the determination may be performed according to the request type initiated by the target capability block. For example, if a capability call request of a capability requirement node is received, it may be considered that a target capability block exists in a public chain of the blockchain network, and if a block creation request of the capability requirement node is received, it may be considered that no target capability block exists in the public chain of the blockchain network. In the steps shown in fig. 5, the query of intelligent capability is realized under the condition of no centralized searching device, so that the capability calling is more convenient and quick, and the scene adaptability is stronger.
FIG. 6 provides a flow chart of interactions between a capability requirement node, a current capability providing node, and other capability providing nodes to enable invocation of a capability to be invoked. Wherein the current capability providing node may be used to execute the above-mentioned capability invoking method, and may be a capability providing node closest to the capability requirement node, and specifically may include the following steps:
step S601, broadcasting the intelligent capability provided by the current capability providing node and other capability providing nodes in the network, and constructing a public chain of a blockchain network;
step S602, the capability requirement node sends a capability query request to the current capability providing node;
step S603, the current capability providing node sends block capability information corresponding to the public chain to the capability demand node;
step S604, the capability requirement node searches the block identification information matched with the capability to be called from the block capability information;
step S605, if the block identification information matched with the capacity to be invoked is found from the block capacity information, the capacity demand node generates a capacity invoking request based on the block identification information and sends the capacity invoking request to the current capacity providing node; if the block identification information matched with the capacity to be called is not found out from the block capacity information, the capacity demand node initiates a block creation request to the current capacity providing node aiming at the capacity to be called;
Step S606, the current capability providing node responds to the capability calling request and acquires the capability evaluation data of the candidate capability providing node from the private chain corresponding to the target capability block; determining a target capability providing node from the candidate capability providing nodes based on the capability assessment data of the candidate capability providing nodes; the current capability providing node responds to a block creation request initiated by the capability demand node, creates a new capability block aiming at the capability to be invoked in a public chain of the blockchain network, and broadcasts the new capability block in the blockchain network so that the capability providing node providing the capability to be invoked in the blockchain network adds own node information into the new capability block; if the new capacity block is updated, the new capacity block is used as a target capacity block;
step S607, the current capability providing node initiates the call of the capability to be invoked to the target capability providing node, and feeds back the capability call result of the capability to be invoked to the capability requirement node;
step S608, the capability demand node performs capability calling effect evaluation, generates capability evaluation data of the capability to be called, and updates the private chain corresponding to the target capability block based on the capability evaluation data of the capability to be called.
In the process, through interaction among the nodes, the calling of the intelligent capability in the block chain network is realized, and the centralized query equipment is not required to be arranged. In addition, based on the query of the blocks on the block chain, the capability requirement node or the capability providing node does not need to carry out additional capability authentication on other capability providing nodes, and the efficiency and the reliability of node calling are improved.
In addition, in order to further promote the dynamic expansion of network capability, an incentive mechanism can be set in the capability calling process. For example, when a capability requirement node initiates a block creation request or when a capability providing node broadcasts a new capability block in the network, an incentive corresponding to the block creation request, such as providing a virtual object or open block signature authority, may be issued by the capability requirement node or the capability providing node.
