Detailed Description
The following describes in detail embodiments of the present invention with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
A first embodiment of the present invention relates to a communication control method. The method is used for reducing the task processing response time delay of the core network when large-scale intensive ultra-reliable low-time-delay communication tasks appear in the communication network.
The following describes the implementation details of the communication control method in the present embodiment in detail, and the following is only for the convenience of understanding the implementation details of the present embodiment and is not necessary for implementing the present embodiment.
Fig. 1 is a flowchart of a communication control method in this embodiment, which may be used for a first network control entity, specifically, the first network control entity may be a core network device in a 5G network. The method may include the following steps.
In step 101, the obtained identifier of the first terminal and the obtained identifier of the second terminal are sent to a block chain network.
The block chain network at least comprises a first network control entity and a second network control entity, wherein the first network control entity is a home network control entity of the first terminal or a roaming network control entity of the first terminal, and the second network control entity is a home network control entity of the second terminal or a roaming network control entity of the second terminal.
It should be noted that the first terminal wants to establish a communication connection with the second terminal, and the communication connection may be a connection for a voice service, a connection for a data service, or a connection for any other communication service. The blockchain network not only includes the first network control entity and the second network control entity, but also includes other network control entities, so as to provide the optimal service for the first terminal and the second terminal.
In step 102, a network control entity in the blockchain network is selected according to the cooperation judgment principle to obtain a network control entity set.
It should be noted that the cooperation judgment principle may include a distance cooperation principle, or a configuration cooperation principle; the distance cooperation principle comprises a home location near principle or a roaming location near principle; the home proximity principle refers to mutual cooperation between network control entities near the home of a communication initiator or a receiver; the roaming place proximity principle refers to mutual cooperation between network control entities in the vicinity of a roaming place of a communication initiator or a receiver. The configuration cooperation principle comprises a whole member participation principle or an operator principle, the whole member participation principle is a principle that all network control entities in the blockchain network participate in cooperation, and the operator principle refers to a principle that only the network control entities of the same operator participate in cooperation. The above collaborative approach may specifically select a configuration for a network environment as desired. The above cooperation principles are only examples, and other non-illustrated cooperation principles are also within the scope of the present application.
The network control entity set selected according to the cooperative judgment principle is a network control entity to participate in negotiation, and the network control entity set at least includes a second network control entity and may also include other network control entities except the first network control entity and the second network control entity.
In step 103, the second terminal is determined whether to meet the communication requirement according to the intelligent contract of the communication authority in cooperation with the network control entity in the network control entity set.
In a specific implementation, according to a cooperation judgment principle, the terminal cooperates with a network control entity in a network control entity set to determine the existence of a second terminal and acquire an identifier of the second network control entity, wherein the cooperation judgment principle comprises a distance cooperation principle and a configuration cooperation principle; and judging whether the second terminal meets the communication requirement or not according to the cooperation judgment principle and the communication authority intelligent contract.
Specifically, any one or a combination of several of the cooperation judgment principles is used to cooperate with a network control entity in the network control entity set to search whether the second terminal exists in the blockchain network, if it is determined that the second terminal exists, the identifier of the second network control entity currently registered by the second terminal is obtained, and other network control entities related to the second terminal, such as a home network control entity of the second terminal, are obtained, so that the network control entity set selected from the blockchain network performs signaling interaction with the first network control entity, and whether the second terminal meets the communication requirement is judged according to the communication authority intelligent contract.
It should be noted that the intelligent contract for communication authority is a pre-established protocol specification for restricting communication between network elements.
Wherein, according to cooperation judgement principle and communication authority intelligence contract, judge whether the second terminal accords with the communication requirement step, include: according to the distance cooperation principle or the configuration cooperation principle, the method cooperates with the network control entity in the network control entity set to determine whether the communication connection obtains communication permission; acquiring a decision response of the second terminal; and judging whether the second terminal meets the communication requirement or not according to the decision response, whether the communication connection obtains the communication permission or not and the communication authority intelligent contract.
For example, when the location of the first terminal is closer to the home, the first network control entity negotiates with the network control entities in the network control entity set by using a home proximity principle; and the location where the second terminal is located is far away, and is currently registered in a network control entity to which a certain roaming place belongs, for example, the second network control entity negotiates with network control entities in a network control entity set by adopting a roaming place proximity principle, determines whether the communication connection between the first terminal and the second terminal can obtain communication permission through interaction among the network control entities, further comprehensively considers decision response of the second terminal to the communication invitation of the first terminal, and specifically judges whether the second terminal meets the communication requirement.
It should be noted that, in the 5G communication network, the first network control entity and the second network control entity may be decentralized core network control planes, and the communication interaction between the core network control plane and the access network control is completed through a cooperation mechanism between edge computing nodes, so as to control the communication connection between the 5G terminals.
The step of obtaining the decision response of the second terminal comprises: sending a communication invitation message to the second terminal, wherein the communication invitation message comprises the identifier of the first terminal, and the communication invitation message is forwarded to the second terminal through a second network access entity; and receiving a decision response returned by the second terminal and forwarded by the second network access entity, wherein the decision response comprises that the second terminal accepts the communication invitation of the first terminal, or the second terminal rejects the communication invitation of the first terminal.
For example, the identifier of the first terminal is 10020, and after receiving the communication invitation message, the second terminal learns the identifier of the first terminal (i.e., 10020) from the communication invitation message, and further determines a decision response, i.e., accepts or rejects the communication invitation of the first terminal, and sends the decision response to the second network access entity, so that the second network access entity forwards the decision response to the first terminal through the blockchain network, where the decision response further includes the identifier of the second terminal (e.g., 10030).
Wherein, according to the decision response, whether the communication connection obtains the communication permission and the communication authority intelligent contract, judging whether the second terminal meets the communication requirement, comprising: according to the communication authority intelligent contract, if the communication connection is determined to obtain the communication permission and the decision response of the second terminal is the invitation of accepting the first terminal, determining that the second terminal meets the communication requirement; otherwise, the second terminal does not meet the communication requirements.
Specifically, when the second terminal agrees to establish the communication connection with the first terminal and the second network control entity agrees to establish the communication connection, that is, negotiations are performed with other network control entities according to the cooperation judgment principle, and the communication connection obtains a communication permission, the second terminal is known to meet the communication requirement according to the communication permission intelligent contract, otherwise, the second terminal does not meet the communication requirement. The communication authority intelligent contract can be a protocol or a specification which is agreed in advance and used for determining the communication authority of the terminal.
In step 104, if it is determined that the second terminal meets the communication requirement, the second terminal cooperates with the network control entity in the network control entity set according to the intelligent contract of the communication path to calculate and obtain the communication path between the first terminal and the second terminal.
In one specific implementation, according to a communication path intelligent contract, the communication path intelligent contract interacts with a network control entity in a network control entity set, and a communication path between a first terminal and a second terminal is obtained through calculation; the communication path intelligent contract is used for calculating communication paths between the first terminal and the second terminal among the plurality of network control entities, and the communication paths comprise routing paths which need to be passed by the first terminal and the second terminal for establishing communication connection.
It should be noted that the communication path intelligent contract is a contract which is pre-agreed among the network control entities and is used for negotiating and calculating the communication path, and whether the first terminal and the second terminal have previously communicated or not, the cost information of the communication and the like can be determined through the communication bill recorded in the communication path intelligent contract; the intelligent contract of the communication path also sets the convention according to the historical state, the current connection state, the communication authority and the communication bandwidth of the terminal, and according to the comprehensive judgment of the information, the right of what kind of communication can be carried out by the first terminal and the second terminal can be determined, for example, only the voice communication is carried out, or not only the voice communication but also the data communication is carried out, and the like, so that each network control entity in the block chain network can carry out negotiation according to the specific information, and the optimal communication path between the first terminal and the second terminal is calculated, for example, when the content of the intelligent contract is searched through the interaction between each network control entity in the block chain network, the first terminal can only carry out the voice communication, but the second terminal can not only carry out the voice communication, but also carry out the data communication, and the communication connection established between the first terminal and the second terminal only supports the voice communication, and then finding an optimal communication path for the voice communication, for example, the current network resources are in shortage, the voice information sent by the first terminal is accessed to the first network control entity through the first access entity, then passes through the third network control entity and then reaches the second network control entity, so that the second terminal obtains the voice information sent by the first terminal, and one route of the route is the shortest communication path between the first terminal and the second terminal in the current network, and the shortest communication path is allocated to the first terminal and the second terminal, so that the two terminals can establish communication connection as soon as possible.
In one particular implementation, a communication path negotiation request is sent to a second network control entity; and responding to a communication path negotiation response returned by the second network control entity, and determining a communication path, wherein the communication path negotiation response comprises the communication path, and the communication path comprises a routing path which needs to be passed by the first terminal and the second terminal for establishing the communication connection.
It should be noted that the communication path may be determined by negotiation between the second network control entity and the first network control entity, or may be a communication path finally determined by negotiation performed by all network control entities in the block chain network, so that it is ensured that the obtained communication path is optimized, that is, the idle communication path is fully utilized, and the utilization rate of the communication path is improved. The communication path includes a routing path that the first terminal needs to pass through to establish a communication connection with the second terminal, for example, a data service or a voice service sent by the first terminal needs to pass through the first network access entity, the gateway 1, the first transmission entity, the gateway 2, the second transmission entity, the gateway 3, and the second network access entity, and is finally received by the second terminal, where the routing path is a communication path between the first terminal and the second terminal.
In step 105, the first terminal is controlled to establish a communication connection with the second terminal according to the communication path.
It should be noted that, after the communication path is determined, the first network control entity may simultaneously notify the first terminal and the second terminal that a communication connection is ready to be started (for example, a voice call is ready to be started, or data service transmission is ready to be started), and then the first terminal may communicate with the second terminal according to the communication path.
In this embodiment, the obtained identifier of the first terminal and the obtained identifier of the second terminal are sent to a blockchain network, a network control entity set is selectively obtained according to a cooperation judgment principle, the network control entity set at least includes a second network control entity, and then cooperates with the network control entity in the network control entity set, whether the second terminal meets a communication requirement is verified according to a communication authority intelligent contract, after the second terminal meets the communication requirement is determined, a communication path between the first terminal and the second terminal is obtained through calculation according to the communication path intelligent contract, and then the first terminal and the second terminal are controlled to establish communication connection according to the communication path. The method has the advantages that the decentralized network control entities replace the existing single core network, the network control entities are subjected to interactive negotiation, and the communication path between the two terminals is determined, so that the obtained communication path can be optimized, the idle communication path can be distributed to the terminals for communication, the utilization rate of the communication path is improved, the response speed is accelerated when an ultra-reliable ultra-low delay task is processed, the response delay of the task is reduced, and the user experience is improved.
A second embodiment of the present invention relates to a communication control method. The second embodiment is substantially the same as the first embodiment, and mainly differs therefrom in that: and obtaining the identifier of the first terminal and the identifier of the second terminal by receiving a communication request which is forwarded by the first network access entity and sent by the first terminal.
Fig. 2 is a flowchart of a communication control method in this embodiment, which is applicable to a first network control entity, specifically, the first network control entity may be a core network device in a 5G network. The method may include the following steps.
In step 201, in response to a communication request sent by a first terminal and forwarded by a first network access entity, an identifier of the first terminal and an identifier of a second terminal are obtained.
Wherein the communication request comprises an identity of the first terminal and an identity of the second terminal.
It should be noted that the communication request needs to be forwarded through the first network access entity and the first transport entity before the first network control entity receives the communication request. The first transmission entity can be replaced by the first edge computing node to improve the computing capacity of the edge network. Moreover, the first terminal and the second terminal are not in the same network control entity, that is, not in the communication range of the same core network; the first terminal or the second terminal may be a 5G terminal, and may also be a 5G service platform.
In step 202, the obtained identifier of the first terminal and the obtained identifier of the second terminal are sent to the blockchain network.
In step 203, a network control entity in the blockchain network is selected according to the cooperation judgment principle, and a network control entity set is obtained.
In step 204, the second terminal is determined whether to meet the communication requirement according to the intelligent contract of the communication authority in cooperation with the network control entity in the network control entity set.
In step 205, if it is determined that the second terminal meets the communication requirement, the communication path between the first terminal and the second terminal is calculated and obtained according to the intelligent contract for communication path and in cooperation with the network control entity in the network control entity set.
In step 206, the first terminal is controlled to establish a communication connection with the second terminal according to the communication path.
It should be noted that steps 202 to 206 in this embodiment are the same as steps 101 to 105 in the first embodiment, and are not repeated herein.
It should be noted that, after controlling the first terminal to establish a communication connection with the second terminal, information is transmitted between the first terminal and the second terminal through a given communication path. Wherein the transmitted information comprises user data, network slice selection data, policy management data, authentication service data, access and mobility management data and network capability opening data.
The first Network Control entity or the first Network Control entity is a decentralized 5G Network Control entity, and the decentralized Network Control entity still includes and supports a logic module of a conventional 5G Network Control plane, and specifically includes the following eight basic logic Function entities, including a Network Slice Selection Function (NSSF) entity, a Network storage Function (NRF) entity, a Unified Data Management Function (UDM) entity, a Policy Control Function (PCF) entity, an Authentication service Function (AUSF) entity, an Access and Mobility Management Function (AMF) entity, a Network capability open Function (Network egress Function, NEF) entity, and a Session Management Function (SMF) entity.

The cooperation of NRF functionality, i.e. exchanging stored data of the original NRF with all (or part of) the other 5G network control entities in the federated blockchain according to a pre-deployed intelligent contract. The cooperation of the UDM function, i.e. exchanging the stored data of the original UDM with all (or part of) the other 5G network control entities in the federated blockchain according to the pre-deployed intelligent contract. The cooperation of the PCF function, that is, according to the pre-deployed intelligent contract, exchanges the stored data in the original PCF, that is, the network decision policy information, etc., with all (or part) of the other 5G network control entities in the federated block chain. And the cooperation of the AUSF functions, namely, the stored data of the original AUSF, namely, the authentication service information and the like are exchanged with all (or part) of other 5G network control entities in the alliance type block chain according to a pre-deployed intelligent contract. The coordination of the AMF function, that is, according to the pre-deployed intelligent contract, exchanges the stored data of the original AMF, that is, access and mobility management information, with all (or part of) other 5G network control entities in the federated block chain. The coordination of the NEF functions, i.e. the exchange of the stored data of the original NEF with all (or part of) the other 5G network control entities in the federated blockchain, i.e. the synchronization of the related service information, is based on a pre-deployed intelligent contract.

In addition, in order to highlight the innovative part of the present invention, elements that are not so closely related to solving the technical problems proposed by the present invention are not introduced in the present embodiment, but this does not indicate that other elements are not present in the present embodiment.
A fourth embodiment of the present invention relates to a communication network control system, as shown in fig. 4, specifically including: a first terminal 401, a first network access entity 402, a first transmission entity 403, a second transmission entity 406, a second network access entity 407 and a second terminal 408, and a blockchain network, the blockchain network at least includes a first network control entity 404 and a second network control entity 405, the first network control entity 404 is a home network control entity of the first terminal 401 or a roaming network control entity of the first terminal 401, and the second network control entity 405 is a home network control entity of the second terminal 408 or a roaming network control entity of the second terminal 408.
It should be noted that the blockchain network further includes a plurality of other network control entities, so that the first terminal or the second terminal can obtain a better communication path.
The first network access entity 402 is configured to forward a communication request sent by the first terminal 401 to the first network control entity 404, forward a communication path sent by the first network control entity 404 to the first terminal 401 when it is determined that the second terminal 408 meets the communication requirement, and forward a connection termination message sent by the first network control entity 404 to the first terminal 401 when it is determined that the second terminal 408 does not meet the communication requirement, where the communication path includes a routing path through which a communication connection needs to be established between the first terminal 401 and the second terminal 408; the second network access entity 407, configured to forward the communication invitation message sent by the second network control entity 405 to the second terminal 408, and forward a decision response returned by the second terminal 408 to the second network control entity 405, where the decision response includes that the second terminal 408 accepts the communication invitation of the first terminal 401, or that the second terminal 408 rejects the communication invitation of the first terminal 401; the first network control entity 404 or the first network control entity 405 is configured to execute the communication control method in the first embodiment or the second embodiment.
It should be noted that the first terminal 401 wants to establish a communication connection with the second terminal 408, and it should be noted that the first terminal 401 and the second terminal 408 that want to perform a communication connection are not in the same network control entity, that is, are not in the communication range of the same core network; the first terminal 401 or the second terminal 408 may be a 5G terminal, and may also be a 5G service platform.
In step 501, the first terminal 401 initiates a communication request, and wishes to establish a 5G communication connection (e.g., performing a voice service or a data service, etc.) with the second terminal 408.
In step 502, the first network access entity 402 forwards the received communication request sent by the first terminal 401 to the first network control entity 404 through the first transmission entity 403.
It should be noted that, the first network control entity 404 sends the identifier of the second terminal 408 (for example, the device number of the second terminal 408, or the mobile phone number corresponding to the second terminal 408) and the identifier of the first terminal 401, which are carried in the communication request, to the blockchain network, and according to the cooperation judgment principle, cooperates with other network control entities in the blockchain network to judge whether the second terminal 408 meets the communication requirement, where the communication requirement may specifically include whether the second terminal 408 exists, a decision response of the second terminal 408, and whether the second network control entity 405 agrees to establish the communication connection.
The cooperative judgment principle may specifically include: the home location proximity principle refers to a principle of mutual cooperation between network control entities in the vicinity of the home location of the communication initiator or the communication receiver. The roaming place proximity principle means that network control entities in the vicinity of a roaming place of a communication initiator or a receiving party cooperate with each other. The whole member participation principle means that all network control entities in the block chain cooperate with each other. The operator principle means that network control entities of the same operator cooperate with each other. And the above collaborative may select configurations as needed specifically for the network environment.
In step 503, the second network control entity 405 to which the second terminal 408 belongs sends the communication invitation information to the second network access entity 407.
It should be noted that the communication invite message is forwarded to the second terminal 408 via the second network access entity 407.
In step 504, the second network access entity 407 interacts with the second terminal 408 to obtain a decision response of the second terminal 408, where the decision response includes whether the second terminal accepts the communication invitation of the first terminal 401.
Specifically, the second network access entity 407 sends a communication invitation message to the second terminal 408, and the second terminal 408 determines to receive the communication invitation of the first terminal 401 or reject the communication invitation of the first terminal 401 according to the identifier of the first terminal 401 carried in the received communication invitation message and the communication environment where the second terminal is located.
In step 505, the second network access entity 407, after receiving the decision response of the second terminal 408, feeds back the decision response to the second network control entity 405.
It should be noted that, after receiving the decision response, the second network control entity 405 negotiates with other network control entities in the blockchain network according to the cooperation judgment principle and the communication authority intelligent contract to determine whether to allow the communication connection to be established. If the negotiation is performed, it is determined that the communication connection is allowed to be established, that is, the second terminal 408 meets the communication requirement, the second network control entity 404 negotiates with the second network control entity 405 to which the second terminal 408 belongs and other network control entities in the blockchain network, and a communication path between the first terminal 401 and the second terminal 408 is calculated according to the communication path intelligent contract. The communication path refers to a routing path that needs to be passed by when the first terminal 401 establishes a communication connection with the second terminal 408 (for example, which network elements are passed by specifically, what routing configuration needs to be made, and the like); otherwise, the communication connection is terminated, and a response result of terminating the establishment of the communication connection is transmitted to the first terminal 401 and the second terminal 408, respectively.
The communication path intelligent contract and the communication authority intelligent contract are communication agreements between the network control entities, and specifically may include recorded communication bills, agreements of communication rights of the first terminal and the second terminal, and the like.
In step 506, the first network control entity 404 informs the first network access entity 402 of the communication path of the communication connection after determining that the second terminal 408 complies with the communication requirements.
In step 507, if it is determined that the second terminal 408 meets the communication requirement, the first network access entity 402 and the second network access entity 407 respectively send a message allowing to establish communication connection to the first terminal 401 and the second terminal 408, so as to establish communication connection; otherwise, if it is determined that the second terminal 408 does not meet the communication requirement, the first network access entity 402 and the second network access entity 407 respectively send a message of rejecting establishing the communication connection to the first terminal 401 and the second terminal 408, and then terminate the communication connection.
In step 508, if it is determined that the communication connection is allowed to be established, the first terminal 401 and the second terminal 408 are controlled to establish a communication connection according to the communication path obtained by negotiation in step 505, so that a session, a data service, or the like can be performed between the first terminal 401 and the second terminal 408.
It should be noted that, in order to assist in establishing communication connection, the decentralized 5G network control entities complete the following three types of tasks through the blockchain network: the first network control entity 404 searches for the identifier of the second network control entity 405 through the blockchain network, and after the first network control entity 404 obtains the identifier of the second network control entity 405, the first network control entity needs to negotiate with the second network control entity 405 and other network control entities in the blockchain network according to a cooperation judgment principle to determine whether the communication connection is allowed to be established, and if the communication connection is determined to be allowed to be established, the first network control entity negotiates with the second network control entity 405 again according to a communication path intelligent contract to obtain a communication path corresponding to the communication connection.
In one specific implementation, the first transmission entity 403 and the second transmission entity 406 may be replaced with the first edge computing node 601 and the second edge computing node 602 shown in fig. 5, in a communication network including the first edge computing node 601 and the second edge computing node 602, the signaling interaction for establishing a communication connection is similar to the signaling interaction of the first transmission entity 403 and the second transmission entity 406 in fig. 4, except that the first edge computing node 601 and the second edge computing node 602 are included in the communication path in fig. 5, and then the communication connection is established via the first network access entity 402 and the second network access entity 407. The first edge computing node 601 and the second edge computing node 603 are both configured to provide connection and data processing services for the first terminal 401 and the second terminal 408 nearby.
The above communication connection establishment is established in a decentralized 5G network framework. A conventional centralized control 5G network framework is shown in fig. 6, and a 5G network is composed of a core network, an access network, and a transport network. The 5G network access network directly faces the user equipment (e.g., a 5G terminal or a 5G service platform), the 5G network access network provides network access and data transmission services for the user equipment, the 5G network transport entity is used for actually transmitting data, and the 5G network core network is used for processing an access request of the user equipment transmitted by the 5G network access network and coordinating the 5G network transport entity to provide data transmission services for the user equipment. The 5G edge computing node is typically located in a 5G network access network, and one or more 5G edge computing nodes may be deployed in each 5G network access network. The 5G edge computing node provides connection and data processing services for the user equipment nearby. The 5G network User plane not only includes a 5G network access network, a 5G edge computing node and a 5G network transmission entity, but also includes a User Plane Function (UPF) entity for interaction between the 5G network access network and the 5G edge computing node. The 5G network control plane entity is typically located in a 5G network core network, the 5G network user plane entity is typically located in a 5G network access network (part) and transport network, and the 5G network control plane entity coordinates the 5G network access network and transport network to provide network connectivity and data transfer services for the user equipment.
As shown in fig. 7, when the 5G network control entity is located near a 5G network access network, generally located near a deployed 5G edge computing node, the decentralized 5G network control entities cooperate with each other to jointly complete the functions of the traditional centralized control 5G network control entity. When the decentralized 5G network control entity and the conventional centralized-control 5G network control entity coexist, the conventional centralized-control 5G network control entity serves as a backup, and the conventional centralized-control 5G network control entity maintains data synchronization with the decentralized 5G network control entity.
In the decentralized 5G network framework, the 5G edge computing node, the 5G network access network and the 5G network transport entity only need to update the configuration file to enable the configuration originally pointing to the traditional 5G network control entity to be updated to point to the local decentralized 5G network control entity or to point to a plurality of nearby decentralized 5G network control entities at the same time.
If the configuration file is updated to point to a plurality of nearby decentralized 5G network control entities at the same time, the 5G network access network, the 5G edge computing node and the 5G network transmission entity need to perform data interaction with the configured and connected decentralized 5G network control entities so as to complete the core network control function.
It should be noted that, when the 5G network access network, the 5G network transport entity, and the network element in the 5G edge computing node interact with the configured decentralized 5G network control entity, the protocol of the interaction is not changed, and a federated block chain form is formed between the decentralized 5G network control entities. The consensus protocol for this blockchain is pluggable (e.g., using the byzantine consensus protocol, etc.). Each decentralized 5G network control entity stores and manages all or part of the relevant data of the conventional 5G network control entity. Each decentralized 5G network control entity provides the full functionality and protocols of a conventional 5G network control entity. Since the network elements in the 5G network access network, the 5G network transport entity, the 5G edge computing node, etc. do not need to identify the change of the decentralized 5G network control entity, these network elements can obtain the same service when connecting any decentralized 5G network control entity. I.e. these network elements are unaware of the differences between the legacy 5G network control entity and the decentralized 5G network control entity. Information is interacted between the decentralized 5G network control entities through intelligent contracts, the intelligent contracts are used for accelerating automatic processing of the interaction information, and related intelligent contracts are deployed in an alliance type block chain formed by the decentralized 5G network control entities in advance.
In the embodiment, the obtained identifier of the first terminal and the obtained identifier of the second terminal are sent to a blockchain network, a network control entity set is selected and obtained according to a cooperation judgment principle, the network control entity set at least comprises the second network control entity and further cooperates with the network control entity in the network control entity set, whether the second terminal meets the communication requirement is verified according to a communication authority intelligent contract, after the second terminal meets the communication requirement is determined, the communication path between the first terminal and the second terminal is calculated and obtained according to the communication path intelligent contract, the existing single core network is replaced by a plurality of decentralized network control entities, and the plurality of network control entities carry out interactive negotiation to determine the communication path between the two terminals, so that the obtained communication path can be optimized, and the idle communication path can be distributed to the plurality of terminals for communication, the utilization rate of the communication path is improved, the response speed is increased when the ultra-reliable ultra-low time delay task is processed, the response time delay of the task is reduced, and the user experience degree is improved.
