Description

Technical Field

[0001] The present invention relates to the field of network technologies, and in particular, to a network capability opening method, apparatus, and readable storage medium. Background Art

[0002] 5G technology is a key foundation for realizing the interconnection of all things and plays a crucial role in promoting the digital transformation of the global economy. 5G-Advanced, with its high-speed transmission and extensive device connection capabilities, will become the core force to support the sustainable development of the digital economy. With the accelerated advancement of digital transformation in various industries, enterprise digitalization has penetrated from auxiliary systems into core links such as production and decision-making. Compared with the Internet era, the demand for network capabilities in digitalization has changed fundamentally. The emergence of new digital services has brought diverse network capability requirements such as security, isolation, and service quality assurance. This demand has given rise to a new business model - "Network as a Service"

[0003] (Network as a Service, NaaS). NaaS provides an innovative business model, but the implementation of its API (Application Programming Interface) requires collaboration across different operators and network devices.

[0004] In traditional network architectures, communication and data sharing between different applications usually need to be achieved by writing specific interfaces and protocols. This approach is often not flexible and efficient enough, and it increases the complexity and maintenance cost of the system. Due to the inconsistent API interface standards, the existing technology can only achieve the opening of network capabilities between a single operator and a certain enterprise, and cannot meet the cross-border and cross-operator network capability opening.

[0005] In addition, the current network slicing technology does not support cross-border roaming. When domestic users roam and access overseas 5G networks, due to cross-operator networks, the originally subscribed VIP QoS (Quality of Service) network priority guarantee will fail, and there is currently no method to achieve the opening of network slicing service guarantees in cross-border roaming scenarios. Summary of the Invention

[0056] Embodiment 1:

[0057] This embodiment provides a network capability open method, which is applied to the first Open Gateway platform of the first operator. As Figure 1 shown, the method includes:

[0058] Step S101: Receive the network slice service quality QoS priority guarantee requirement of the user.

[0059] In this embodiment, the user is a domestic or overseas user. The domestic / overseas user raises the network slice QoS priority guarantee requirement on the first Open Gateway platform of the first operator, and the first Open Gateway platform receives the network slice QoS priority guarantee requirement of the user.

[0060] It should be noted that Open Gateway is a general API (Application Programming Interface) framework designed for the network. Through such general APIs, Open Gateway can change the way developers and enterprises use the operator's network, and open the network connection ability of the operator to all walks of life. Open Gateway aims to build a simple, agile and efficient network architecture to promote communication and data exchange between different applications. Open Gateway enables the operator to provide application functions (Application Function, AF) within the 5G network architecture to customers. The core ability of AF is to process the internal and external transfer of information and protocol conversion, and call the network resources of the operator according to the requirements. According to the 3GPP protocol, Open Gateway must be connected to the network function (Network Function, NF) through a standardized interface to securely obtain the basic network ability and provide it to AF. Its key capabilities include authentication and authorization, API consumer identification, profile management, access control, policy enhancement, infrastructure policy, service policy, security, routing and traffic control, protocol conversion, and mapping from API to network interface, etc. The specific logical architecture diagram is as Figure 2 shown. Open Gateway adopts a distributed architecture design, aiming to achieve high availability and fault tolerance. At the same time, its open source feature brings greater flexibility and customizability to users, allowing users to customize and expand according to specific application requirements. The logical architecture of Open Gateway mainly includes the following parts:

[0061] 1) Front - end application layer. The function of the front - end application layer is to provide users with websites / mobile applications, enabling users to interact with the Open Gateway. The applications in this part can be web - based or customized for mobile devices. They exchange information with the Open Gateway through APIs, sending requests and receiving responses to complete tasks such as data sharing and transmission.

[0062] 2) API gateway layer. In the network architecture of the Open Gateway, the API gateway layer plays a key role. It connects the front - end application layer and the back - end service layer. This layer can identify the request type, route the requests to the corresponding back - end service instances, and perform load balancing and caching at the same time. The main responsibility of the API gateway layer is to process and forward requests, delivering them to the target application. In addition, the gateway layer can support multiple communication protocols, such as HTTP (Hypertext Transfer Protocol), TCP (Transmission Control Protocol) / IP (Internet Protocol), MQTT (Message Queuing Telemetry Transport), etc., to meet different application requirements.

[0063] 3) Back - end service layer. The back - end service layer of the Open Gateway is responsible for providing core capabilities, including payment processing, data analysis, and API management, etc. This layer consists of multiple service instances, and each instance undertakes the task of processing specific requests. This distributed design helps to enhance the stability and efficiency of the system. In addition, the service layer also provides a series of key services, including authentication, authorization, messaging, and storage management, etc. These capabilities are all to ensure secure and efficient communication between applications.

[0064] Step S102: Send a QoSProfile configuration file query request to the second Open Gateway platform of the second operator through the QoSProfile API (Quality of Service Profile Application Programming Interface) according to the user's network slice QoS priority guarantee requirement; wherein, the first operator and the second operator belong to different operators, and when the first operator is a domestic operator, the second operator is a foreign operator; or when the first operator is a foreign operator, the second operator is a domestic operator.

[0065] In this embodiment, the first Open Gateway platform and the second Open Gateway platform are connected by an east-west interconnection dedicated line, and each is connected to the network slice management system of its affiliated operator. The QoSProfile API is based on the OpenGateway standard. When the first Open Gateway platform sends a QoSProfile configuration file query request to the second Open Gateway platform through the QoSProfile API, the second Open Gateway platform returns a QoSProfile configuration file that meets the QoS priority guarantee requirements of the network slice to the first Open Gateway platform according to the QoSProfile configuration file query request.

[0066] It should be noted that both the first Open Gateway platform and the second Open Gateway platform are deployed with network slice APIs that conform to the Open Gateway standard. One acts as a service provider and the other acts as a service requester. Both are based on these APIs when sending and receiving messages.

[0067] Step S103: Receive the QoSProfile configuration file returned by the second Open Gateway platform that meets the QoS priority guarantee requirements of the network slice;

[0068] Step S104: Send a request for enabling the network slice QoS priority guarantee function to the second Open Gateway platform through the QualityOnDemand API (Quality on Demand API) based on the QoSProfile configuration file, so that the second Open Gateway platform enables the network slice QoS priority guarantee function for the user according to the request.

[0069] In this embodiment, the QualityOnDemand API is based on the Open Gateway standard. When the first OpenGateway platform calls the QualityOnDemand API interface through the east-west interconnection dedicated line to request the second Open Gateway platform to enable the network slice QoS priority guarantee function, the second Open Gateway platform enables the network slice QoS priority guarantee function for the user according to the request. Specifically, the second Open Gateway platform interacts with the network slice management system of the second operator according to the request to enable the network slice QoS priority guarantee function for the user.

[0070] In an optional embodiment, domestic / overseas users respectively access the 5G core network wirelessly through 5G CPE (Customer Premises Equipment) devices to achieve Internet access. The users access the POP (Point of Presence) points of the SD-WAN (Software-Defined Wide Area Network) backbone network to achieve dedicated line connection. After the second Open Gateway platform receives the request from the user to enable the QoS priority guarantee function of the network slice, it sends the enabling requirement for the QoS priority guarantee function of the network slice to the network slice management system according to the request, so that the network slice management system sends the network guarantee related parameters of the user to the PCC (Policy Control and Charging) to apply for invoking the QoS priority guarantee, and the PCC triggers the template policy pre-configured in the core network PCF (Policy Control Function) network element to take effect, thereby enabling the QoS priority guarantee function of the network slice for the user. Among them, the network guarantee related parameters include the guarantee number MSISDN (Mobile Subscriber International ISDN), the guarantee duration (duration), the service address (IP), etc.

[0071] Optionally, after sending the request for enabling the QoS priority guarantee function of the network slice to the second Open Gateway platform through the Quality On Demand API based on the QoS Profile configuration file, the method further includes:

[0072] Receiving the enabling success information and SessionId (session identifier) returned by the second Open Gateway platform.

[0073] In this embodiment, after successful enabling, the second Open Gateway platform returns the success information and SessionId.

[0074] It should be noted that the network capability open method provided by the present invention aims to give full play to the advantages of the Open Gateway API for quick enabling, flexible access to the 5G network, and rapid networking of the SD-WAN, rely on the network slice API to ensure the network transmission quality, build a dedicated line service that is easy to deploy, quickly enabled, highly guaranteed, and cross-operator, support the network slice service guarantee for cross-border roaming scenarios, and explore new revenue growth points for international business.

[0075] In a specific embodiment, due to the increasingly strong demand of customers in all walks of life for cross-border and cross-regional dedicated lines with quick activation and high-priority service guarantee, and at the same time, there are pain points such as complex customer access environments, difficult "last mile" deployment, and long activation time. The present invention proposes a solution for realizing interconnection and interoperability between domestic operators' Open Gateway platforms and overseas operators. At the same time, the domestic operators' Open Gateway platforms are connected to the network slice management system, and the network QoS capabilities are called on demand. Based on the SD-WAN networking capabilities of the terminals, a complete set of Open Gateway + SD-WAN + 5G slice solutions are formed, as Figure 3 shown: Users inside / outside the country respectively access the 5G core network wirelessly through 5G CPE devices to achieve Internet access. Users access the SD-WAN backbone network POP points to achieve dedicated line connection. When users have the need for network slice guarantee, domestic and overseas operators can call the network slice APIs based on the Open Gateway standard with each other through the Open Gateway platform to activate the network slice service and guarantee the network quality of the users' access.

[0076] Based on Figure 3 the Open Gateway cross-operator capability invocation architecture diagram shown, taking the case where overseas users initiate the network slice QoS priority guarantee requirement as an example, as Figure 4 shown, the network capability open method may include the following steps:

[0077] Step 1: Overseas users raise the network slice QoS priority guarantee requirement on the operator's Open Gateway platform. The overseas operator's Open Gateway platform (abbreviation: overseas operator OG platform) calls the QoSProfile API interface and executes the functions of screening and querying the network QoSProfile configuration files of both parties;

[0078] Specifically, the overseas operator OG platform queries the network slice QoS priority configuration data of the other party's network through the QoSProfile API, that is, the overseas operator OG platform sends a "QoSProfile configuration file query request" to the domestic operator OpenGateway platform (abbreviation: domestic operator OG platform) through the QoSProfile API interface. Then, the domestic operator OG platform returns a QoSProfile configuration file that meets the "network slice QoS priority guarantee requirement" of overseas users.

[0079] Step 2: The overseas operator's OG platform calls the QualityOnDemand API interface through the east-west interconnection dedicated line to request the other party to enable the network slice QoS priority guarantee function. After successful activation, a success message and SessionId will be returned;

[0080] It should be noted that the network slice API based on the Open Gateway standard is a series of APIs, including the QoSProfile API (Quality of Service Configuration API) and the QualityOnDemand API (Quality on Demand Guarantee API). These APIs are deployed on both platforms to enable mutual calls. The QualityOnDemand API can select a network priority according to the user's service requirements to guarantee the user's network service quality.

[0081] Step 3: After receiving the request sent by the other party, the domestic operator's OG platform issues the requirement for enabling the network slice QoS priority guarantee function to the network slice management system through the southbound interface service 5GSlicingPlatform_SliceRequestSending;

[0082] Among them, 5GSlicingPlatform_SliceRequestSending is a request message used to trigger the activation of the 5G network slice priority.

[0083] Step 4: The network slice management system interfaces with the PCC (Policy Control and Charging, which is used to manage the policies of data traffic in the 5G network and ensure the service quality of users) platform, and transmits parameters such as the MSISDN (guarantee number), duration (guarantee duration), and IP (service address) of overseas users to apply for calling the QoS priority guarantee;

[0084] Among them, the QualityOnDemand API interface will carry information such as MSISDN, duration, and IP.

[0085] Step 5: The PCC platform triggers the activation of the template policy pre-configured in the core network PCF network element, establishes an end-to-end slice QoS guarantee mechanism for the user, and returns a message indicating successful slice activation.

[0086] Based on Figure 3 the shown Open Gateway cross-border and cross-operator capability call architecture diagram, taking the case where a domestic user initiates a network slice QoS priority guarantee requirement as an example, as Figure 5 shown, this network capability open method may include the following steps:

[0087] Step 1: Domestic users raise the requirement for network slice QoS priority guarantee on the operator OG platform. The domestic operator OG platform calls the QoSProfile API interface and executes the functions of screening and querying the QoSProfile configuration files of both networks.

[0088] Step 2: The domestic operator OG platform calls the QualityOnDemand API interface through the east-west interconnection dedicated line to request the other party to enable the network slice QoS priority guarantee function. After successful enabling, it will return a success message and SessionId.

[0089] Step 3: After receiving the request from the other party, the overseas operator OG platform issues the requirement for enabling the network slice QoS priority guarantee function to the network slice management system through the southbound interface service 5GSlicingPlatform_SliceRequestSending.

[0090] Step 4: The network slice management system interfaces with the PCC (Policy Control and Charging, which is used to manage the policies of data traffic in the 5G network to ensure the service quality of users) platform, and transmits parameters such as the MSISDN (guarantee number), duration (guarantee duration), and IP (service address) of overseas users to apply for calling QoS priority guarantee.

[0091] Step 5: The PCC platform triggers the activation of the pre-configured template policy in the core network PCF network element, establishes an end-to-end slice QoS guarantee mechanism for users, and returns a message indicating successful slice enabling.

[0092] It should be noted that the network capability open method provided by the present invention realizes cross-border and cross-operator network capability open through the Open Gateway API, promotes seamless connection and efficient collaboration between different networks and services, improves the user experience. At the same time, based on the fast network deployment ability of SD-WAN, combined with 5G network slice technology, it ensures the stability of wireless access and service quality, and can provide users with guaranteed elastic network services.

[0093] The network capability opening method provided by the embodiment of the present invention first receives the network slice service quality (QoS) priority guarantee requirement of a user; and sends a QoSProfile configuration file query request to the second Open Gateway platform of a second operator through a quality of service configuration application programming interface (QoSProfile API) according to the network slice QoS priority guarantee requirement of the user; wherein, the first operator and the second operator belong to different operators, and when the first operator is a domestic operator, the second operator is a foreign operator; or when the first operator is a foreign operator, the second operator is a domestic operator; then receives the QoSProfile configuration file returned by the second Open Gateway platform that meets the network slice QoS priority guarantee requirement; and then sends a request for enabling the network slice QoS priority guarantee function to the second Open Gateway platform through a Quality On Demand API based on the QoSProfile configuration file, so that the second Open Gateway platform enables the network slice QoS priority guarantee function for the user according to the request. The present invention realizes cross-border and cross-operator network capability opening based on the Open Gateway platform and network slice APIs based on the Open Gateway standard, ensures the service quality and opening efficiency of network slices in cross-border roaming, and thus significantly improves the user experience during cross-border roaming. It solves the problems that the prior art cannot meet cross-border and cross-operator network capability opening, and that the network slice technology cannot guarantee service quality and realize service opening in the cross-border roaming scenario.

[0094] Embodiment 2:

[0095] As Figure 6 shown, the present embodiment provides a network capability opening method applied to the second Open Gateway platform of a second operator, and the method includes:

[0096] Step S201: Receive a QoSProfile configuration file query request sent by the first Open Gateway platform of a first operator through a QoSProfile API according to the network slice QoS priority guarantee requirement of a user after receiving the network slice QoS priority guarantee requirement of the user, wherein the first operator and the second operator belong to different operators, and when the first operator is a domestic operator, the second operator is a foreign operator; or when the first operator is a foreign operator, the second operator is a domestic operator.

[0097] In this embodiment, the first Open Gateway platform and the second Open Gateway platform are connected through an east-west interconnection dedicated line, and are respectively connected to the network slice management system of their respective operators. The QoSProfile API is based on the OpenGateway standard.

[0098] Step S202: Return a QoSProfile configuration file that meets the QoS priority guarantee requirements of the network slice to the first Open Gateway platform according to the QoSProfile configuration file query request.

[0099] In this embodiment, when the first Open Gateway platform sends a QoSProfile configuration file query request to the second Open Gateway platform through the QoSProfile API, the second Open Gateway platform returns a QoSProfile configuration file that meets the QoS priority guarantee requirements of the network slice to the first Open Gateway platform according to the QoSProfile configuration file query request.

[0100] Step S203: Receive a request for enabling the QoS priority guarantee function of the network slice sent by the first Open Gateway platform through the QualityOnDemand API based on the QoSProfile configuration file.

[0101] In this embodiment, the QualityOnDemand API is based on the Open Gateway standard.

[0102] Step S204: Enable the QoS priority guarantee function of the network slice for the user according to the request.

[0103] In this embodiment, when the first Open Gateway platform calls the QualityOnDemand API interface through the east-west interconnection dedicated line to request enabling the QoS priority guarantee function of the network slice from the second Open Gateway platform, the second Open Gateway platform enables the QoS priority guarantee function of the network slice for the user according to the request.

[0104] Optionally, the enabling the QoS priority guarantee function of the network slice for the user according to the request specifically includes:

[0105] Interact with the network slice management system of the second operator according to the request to enable the QoS priority guarantee function of the network slice for the user.

[0106] Specifically, the second Open Gateway platform sends an activation requirement for activating the network slice QoS priority guarantee function to the network slice management system according to the request, so that the network slice management system sends the user's network guarantee related parameters to the Policy and Charging Control function (PCC) according to the activation requirement for applying to invoke the QoS priority guarantee, and the PCC triggers the template policy pre-configured in the core network policy control function (PCF) network element to take effect, thereby activating the network slice QoS priority guarantee function for the user.

[0107] Optionally, after activating the network slice QoS priority guarantee function for the user according to the request, the method further includes:

[0108] Returning an activation success message and a session identifier (SessionId) to the first Open Gateway platform.

[0109] It should be noted that the network capability open method provided by the present invention realizes cross-border and cross-operator network capability open through the Open Gateway API, promotes seamless connection and efficient collaboration between different networks and services, improves the user experience. At the same time, based on the fast network formation ability of SD-WAN, combined with the 5G network slice technology, it ensures the stability of wireless access and service quality, and can provide guaranteed elastic network services for users.
