Detailed Description

The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

Aiming at the problems that the current network deployment mode is long in time, complex in configuration data and low in flexibility, and the network cannot be rapidly on line to provide network service capability, the invention provides a deployment method of a distributed network.

Fig. 1 illustrates a flow diagram of a method of deployment of a distributed network, according to some embodiments of the present disclosure. As shown in fig. 1, the deployment method of the distributed network is executed by a network function NF service management function, and includes steps S102 to S110.

In step S102, it is determined whether the network is capable of meeting the service requirements of the user equipment. In some embodiments, service request information sent by a user equipment is received, where the service request information includes service function requirement information and service performance requirement information. For example, the user initiates a navigation service request, the service function requirement information is navigation, and the service performance requirement information is positioning accuracy, sensing range and the like.

The network manager synchronizes the network or the configuration file of the NF in the network to the NF service management function, which can obtain the static information of the NF in the network or the network, such as the resource information of the central processing unit (Central Processing Unit, CPU for short) and the graphics processing unit (Graphic Processing Unit, GPU for short). After the service requirement of the user is acquired, the network requirement information corresponding to the service requirement is analyzed and acquired through analyzing the service requirement, and whether the network can meet the service requirement can be analyzed according to the network requirement information.

In some embodiments, determining whether the network is capable of meeting the traffic demand comprises: determining network demand information corresponding to service demands; and determining whether the network can meet the service requirement according to the network requirement information and the configuration information of the NF existing in the network.

The basic configuration requirement information refers to static configuration information of the network required by the service requirement of the user, and the static configuration information is measured by basic configuration indexes, and the basic configuration indexes include coverage range of the network and the like.

For example, the service requirement of the user needs to acquire data in the location area of the user, and the coverage of the current network needs to be determined, for example, whether the current network can acquire data in the location area of the user is determined through a tracking area identification (Tracking Area Identity, abbreviated as TAI) table of the current network.

The service quality requirement information refers to network quality information required by the service requirement of the user, and the network quality information has different measurement indexes according to the service requirement of the user.

The index corresponding to the network demand information may be an existing index in the network or a newly introduced index. In the case that the index corresponding to the network demand is an existing index in the network, whether the network can meet the service demand is determined by comparing the demand value and the current value of the index. In case the index to which the network demand corresponds is a newly introduced index, i.e. an unused index in the network, the network is considered to not fulfill such network demand, i.e. the network cannot fulfill the traffic demand.

For example, when the service requirement of the user is related to a communication transmission service, such as a real-time communication service, a connection index (Network Connection Indicator, abbreviated as NCI) may be used to measure the network service quality, where NCI includes throughput, delay, jitter, packet loss, reliability, and the like. After determining that indexes corresponding to the service demands of the users include throughput, time delay, jitter, packet loss and reliability, determining whether the conditions of the throughput, time delay, jitter, packet loss and reliability of the current network can meet the service demands of the users according to the configuration information of the NF in the network. For example, the network throughput required by the service requirement of the user has a required value of 70mb/s, and the current value of the throughput of the current network has a current value of 80mb/s, so that the current value of the throughput of the current network can meet the throughput required by the service requirement of the user.

When the service requirement of the user is navigation, the network service quality can be measured by using a sensing index (Sensing Indicator, abbreviated as SI), and the SI comprises positioning precision, sensing range and the like. For example, the positioning accuracy required by the service requirement of the user is the maximum distance between the positioning result and the real position, i.e. the error radius is smaller than 5 meters, and the positioning accuracy of the current network is 6 meters, so that the current value of the positioning accuracy of the current network cannot meet the positioning accuracy required by the service requirement of the user.

Where the user's business needs are related to a computing service, such as a cloud computing service, a computing metric (Computing Indicator, abbreviated CI) may be used to measure network quality of service, including computing service response time, computing efficiency, etc.

Where the user's traffic demand is related to intelligent services, such as regional congestion state prediction, the network quality of service may be measured by an intelligent indicator (Artificial Intelligence Indicator, abbreviated as AII), which includes inference accuracy/precision, inference latency, reusability, etc.

Where the business needs of a user are related to a Data service, such as processing large-scale Data, a Data Indicator (DI) may be used to measure network quality of service, where DI includes Data set type, size, etc.

The service requirements of users often correspond to the comprehensive network service quality requirements, so NF service management functions generally comprehensively determine the network service quality requirements from aspects of connection, sensing, computing, intelligence, data, and the like.

At present, the 5G service quality parameter (such as 5 QI) only reflects the indexes related to the connection service, such as the connection indexes including bandwidth, time delay, jitter and the like, and the present disclosure also considers the network indexes related to the new service (such as intelligence, data, calculation and perception) of the future network (6G), so that the service demand can be analyzed more deeply and according with the evolution direction of the future network based on the present disclosure, so that the network can provide more intelligent and extreme service for the user based on the analysis of the service demand.

When the network demand information corresponding to the service demand of the user is determined, a plurality of indexes are adopted to determine the network service quality demand corresponding to the service demand of the user, and the requirements of new service fragmentation, maximization and high real-time performance of the future 6G network are met. That is, the requirements of high-precision sensing and calculation efficiency of environments in haptic communication, such as introducing some new network indexes for new services in future networks, are met.

The network deployment method meets the requirements that the future network can dynamically and flexibly design and construct the network according to the service, and meets the direction that the future network provides more intelligent and personalized services for users.

In step S104, in the case that the network cannot meet the service requirement, a profile set is generated according to the service requirement, where the profile set includes a profile corresponding to each NF of the one or more NFs.

Under the condition that the current network can not meet the service requirements of the users, the network is deployed so that the deployed network can meet the service requirements of the users, and the dynamic deployment of the network according to the requirements of the users can be realized.

In some embodiments, an NF of the one or more NFs refers to an existing NF in the network or to a newly deployed NF in the network. That is, the business requirements are parsed and NF associated with the business requirements is determined. In the case where the NF associated with the traffic demand is an existing NF in the current network, the existing NF in the network is reconfigured according to the traffic demand. In the case that the NF related to the service requirement is not in the current network, the NF is added in the current network and is configured according to the service requirement.

For example, when the current network cannot meet the navigation requirement of the user, that is, the positioning accuracy of the current network is insufficient, NF can be newly deployed in the network to increase the density of NF, thereby improving the signal strength and the positioning accuracy. For another example, when the throughput of the current network cannot meet the service requirement of the user, the network path can be optimized, so that time delay and packet loss are reduced, and the efficiency of data transmission is improved.

For example, when the positioning accuracy and the sensing range of the current network cannot meet the service requirements of users, NFs can be newly deployed in the network and service areas of sensing related NFs can be reconfigured so as to increase the density of NFs, thereby improving the signal strength, positioning accuracy and sensing areas.

For example, when the response time and the calculation efficiency of the calculation service of the current network cannot meet the service demands of the user, more calculation resources can be allocated to the user so as to improve the calculation speed, thereby reducing the response time of the calculation service and improving the calculation efficiency.

For example, when the intelligent analysis type of the current network cannot meet the service requirement of the user, an intelligent related NF can be newly deployed in the network, and the NF configures an associated analysis Identifier (ID) to support the intelligent analysis service requirement of the user.

For example, when the type and size of the data set of the current network cannot meet the service requirement of the user, registration information of NF, such as service area and data network name (Data Network Name, abbreviated as DNN) and the like, can be reconfigured to increase data sources, thereby enriching data types and increasing data volume.

For example, when the network basic configuration information of the current network cannot meet the service requirement of the user, the registration information of the NF can be reconfigured, such as adding the TAI of the NF service, so as to enlarge the area of the NF service.

In some embodiments, the NF is a core network NF or an access network device, and the access network device is a mobile network access device or a fixed network access device.

And determining whether the current network can meet the service requirements of the user according to the existing basic configuration of the network and the existing network service quality. And if the current network can meet the service requirements of the user, providing corresponding services for the user. If the current network can not meet the service requirements of the user, corresponding network deployment is carried out according to the service requirements of the user, so that the deployed network can meet the service requirements of the user.

The configuration file set is generated according to the service requirements, and the network is deployed, so that the dynamic and local configuration of the network based on the service requirements is realized, and differentiated services of users are met through the customized distributed network, so that more new scenes and new capabilities supported by the future network can be matched, and the service requirements of future service fragmentation, maximization and high real-time performance are matched.

In step S106, a corresponding configuration file is sent to each NF, so that each NF performs self-configuration.

The NF service management function sends the configuration file to the NF to enable the NF to perform self-configuration, so that a plurality of NF can perform self-configuration at the same time, manual intervention is not needed, thereby improving the efficiency of network deployment, improving the accuracy of network deployment, in addition, increasing the flexibility of network deployment, avoiding planning the network deployment in advance, and realizing the requirement of flexibly configuring the network according to the user requirement.

In step S108, service information supported by each NF is received.

After NF self-configuration is completed, the supported service information is registered with the NF service management function. The service information includes a unique identifier corresponding to the NF, a service supported by the NF, a full-defined name (Fully Qualified Domain Name, abbreviated as FQDN) or an IP address corresponding to the NF, and the like.

Unified management of NFs to be deployed in a network is realized through an NF service management function. The NF only needs to interact with the NF service management function from the acquisition of the configuration file to the registration of the supported service information after the self-configuration is completed, so that the flow is simple, the configuration is convenient, and the flexibility is strong.

In step S110, based on the service information of each NF, registration is performed with the network registry to complete network deployment.

After the NF service management function receives the service information of all NFs, the NF service management function registers with the network registration center based on the service information, thereby completing the deployment of the network.

In some embodiments, the network identification may be a network slice identification, a mobile country code (Mobile Country Code, MCC for short) + a mobile network code (Mobile Network Cod, MNC for short) + a number, or a completely new numbering system for identifying the distributed network.

In some embodiments, the network access mode may be a 6G/5G/4G mobile network, wireless fidelity (Wireless Fidelity, wi-Fi for short), satellite access, near field communication, etc.

In some embodiments, network location information refers to the physical or logical location of a device, node, or resource in a network. The network location information facilitates determining the network topology of the various components in the network. The network location information helps to account for overall call latency issues when selecting network services. The data transmission path of the NF can be determined according to the network location information, so that the NF providing the service can be selected for the user according to the geographical location of the user, and the network service with low delay can be provided.

In some embodiments, network coverage describes the transmission range and availability of network services. Network coverage helps to take into account issues of continuity of network services when selecting network services. The user is within network coverage and network services are available. Network coverage in different areas may have different quality of network service.

In some embodiments, the network operator is responsible for validating trusted schemes, which include various security measures and procedures to ensure that the network and communications are secure. The network operator considers the problem of trusted schemes when negotiating network services.

In some embodiments, the network capability information includes network function information and network performance information. Network function information such as a connection function that the network can provide, an intelligent function, a sense-of-general function, etc., wherein the connection function is, for example, a function that the current 5G network can provide connection services such as the internet for the user, etc., and the intelligent function and the sense-of-general function are, for example, a function that the future network can provide personalized specific services for the user. That is, the network-level service information can embody characteristics of a future network.

The intelligent function of the network means that the network has certain intelligent and automatic capability, and can identify, analyze, make decisions and respond to different network events and conditions, such as managing and optimizing network operation by applying different digital models, automatically distributing network resources and the like.

The general sense function of a network refers to the ability of the network to sense, identify and understand various network and communication conditions, for example, the network can sense the quality of network connection, including delay, packet loss rate, bandwidth, etc., so as to identify performance problems in the network, take certain measures to optimize the connection, etc.

In some embodiments, the network performance information includes network capacity, network load, and the like. Network capacity refers to the maximum amount of data that the network can carry, measured, for example, by the data transmission rate, the network bandwidth. Network capacity is used to determine the possible bearer capability of the network, which may lead to congestion and performance problems if the network capacity is insufficient.

Network load refers to the actual amount of data or load currently experienced by the network. Network load is an implemented measure of network traffic, e.g., measured by throughput, bandwidth utilization, etc. The network load is used to evaluate the current operating state of the network to determine if the network is operating properly or if there is a congestion or overload condition.

In some embodiments, the network registry may be a logically centralized network registry, or may be a distributed network registry made up of a plurality of distributed nodes. The distributed network registry may be implemented by blockchain technology, with multiple distributed blockchain nodes making up the network registry.

The NF service management function can send configuration files to all the NFs to be deployed at one time, after the self-configuration of all the NFs is completed, network-level service information is generated based on service information supported by all the NFs, and the registration of all the NFs is completed in a network registration center through the network-level service information of network dimensions, so that the efficiency of network deployment is improved.

In step S202, the network manager synchronizes the configuration file of the network or the network element (NF) to the NF service management, including static information (e.g. CPU, GPU resource information) of the network or the network element.

In step S204, a User Equipment (UE) initiates a service request to a network, where the carried information includes service functions, service performance requirements, and the like.

In step S206, NF service management in the network analyzes the service request, analyzes and obtains corresponding network requirement information, including network quality of service requirement and network basic configuration information. The NF service management analyzes whether the current network can meet the service requirement, and if not, generates a network element configuration file according to the network requirement information.

In step S208, the NF service management sends the network element configuration file to the core network NF, so that the core network NF completes the self-configuration.

In step S210, the core network NF sends a service registration request to the NF service management function, and registers the service supported by itself to the NF service management function in the network. The service registration request includes NF identification, NF supported services, NF corresponding FQDN/IP address, etc.

In step S212, since the core network NF is managed by the NF service management function, the core network NF can acquire information of each other from the NF service management function, thereby enabling mutual discovery and automatic connection.

In step S214, the NF service management sends the network element configuration file to the access network device (which may include the mobile network and the fixed network access device), so that the access network device completes the self-configuration.

In step S216, the access network device sends a service registration request to the NF service management function, and registers the service information supported by itself to the NF service management function. The service registration request includes a device identification, a service supported by the device, a FQDN/IP address corresponding to the device, and the like.

In step S218, since the core network NF and the access network device are managed by the NF service management function, the access network device and the core network NF can acquire information of each other from the NF service management function, thereby enabling mutual discovery and automatic connection.

In step S220, the NF service management function generates network-level service information based on the core network NF service information and the access network apparatus service information.

In step S222, the NF service management function transmits a network service registration request to the network registry.

In step S224, after the network registry receives the request, a network level Profile (Profile) is stored.

In step S226, the network registration center replies a network service registration response to the NF service management function, indicating that the registration is successful.

In the above steps, the core network NF and the access network device are included as two examples, and the deployment of the core network NF and the access network device is not a priority. In addition, a network including the left access network device, the core network NF, and NF service management in fig. 2 may be referred to as a (6G) distributed network a, a network including the right core network NF may be referred to as a (6G) distributed network B or a functional network, and the functional network refers to a network providing a specific service to a user, for example, the above-mentioned network having an intelligent function, a network having a sense of general function, or the like. An automatic open path can be realized between the distributed network a and the distributed network B or the functional network, for example, a connection request is sent to the distributed network B or the functional network through the distributed network a, and the distributed network B or the functional network accepts the connection request, so that services and the like are provided for users cooperatively.

The above is a step of network deployment. In addition, the NF in the network is configured and modified, and similar management can be performed through the NF service management function, so that the NF realizes self-updating and updates the registration information in the network registration center at one time.

Fig. 3 illustrates a flow diagram of an update network deployment, according to some embodiments of the present disclosure. The flow of updating the network deployment shown in fig. 3 includes steps S302 to S308.

In step S302, an updated configuration information set is obtained, where the updated configuration information set includes an updated configuration file corresponding to each NF to be updated of the one or more NFs to be updated.

The network manager or the configuration service center modifies the configuration file, for example, modifies data parameters in the configuration file.
