Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method for providing network services and related devices and systems. Background Art

[0002] With the development of communication technology, an endless stream of network services provide convenience for users. Current networks can provide a variety of network services, such as quality of service (QoS), hierarchical quality of service (HQoS), segment routing policy (SR policy), deterministic networking (DetNet), network slicing, network measurement, virtual private network (VPN), or application-aware networking (APN).

[0003] When the network provides network services to applications, it is necessary to implement specific network services by identifying the network service identifier of the network service carried in the message. Each network service usually has its own service identifier. For example, the network service identifier of the SR policy includes the binding segment identifier (binding segment identifier, Binding SID or BSID), the network service identifier of the network measurement includes the flow identifier (flow ID), and the network service identifier of the APN includes the APN ID. Regarding network service identifiers, they can be divided into two categories according to the objects they are oriented to: User-to-Network Interface (UNI) identifier and Network-to-Network Interface (NNI) identifier, where the UNI identifier is an identifier assigned to users or applications, and the NNI identifier is an identifier for internal network services.

[0004] Furthermore, if the application requests the network to use a network service, the network also needs to expand an interface that supports the network service for the application in the process of providing the network service to the application.

[0005] As network services continue to increase, the types of network service identifiers and network service interfaces are becoming increasingly complex. The above factors have raised the threshold for applications to use network services and have made it difficult to efficiently achieve the integration of applications and networks. Summary of the invention

[0006] In a first aspect, an embodiment of the present application proposes a method for providing a network service, comprising:

[0007] The first server obtains first network service information, which includes resource information of the first network service; based on a first request sent by a client, the first server sends a first response to the client, and the first response carries a first network service identifier determined based on the first network service information.

[0008] In one possible implementation, based on a first request sent by a client, the first server determines the first network service corresponding to the client; the first server sends a first response to the client, and the first response carries a first network service identifier determined based on resource information of the first network service.

[0009] In an embodiment of the present application, the first server is an application-related server, or an application service provider-related server. The client is an application-related client, and the client sends a service-related service message. It should be noted that the service message in the embodiment of the present application may also be an application-related application message, for example, replacing the service message with an application message, which is not limited in the embodiment of the present application. The client in the embodiment of the present application may be a client or server of various applications, including but not limited to: video service applications, such as video conferencing applications, video chat applications, short video applications, or live broadcast applications; audio service applications, such as voice chat applications; extended reality (XR) services, virtual reality (VR) services, augmented reality (AR) services, or mixed reality (MR) services, etc.

[0010] In an embodiment of the present application, after the first server obtains the first network service information, it obtains the ability to allocate the first network service to the client. Based on the first request sent by the client, the first server determines the first network service corresponding to the client. Then, the first server can send a first response to the client, and the first response carries the first network service identifier determined by the first server from the resource information of the first network service. The network provides a network service identifier for identifying the network service. After the client obtains the network service identifier, the business message sent by the client can request the corresponding network service by carrying the network service identifier. The network provides an interface between the network service and the network service identifier to provide various types of network services to the application, so that the application can request network services in a refined manner. The network can provide network services to applications more conveniently to better meet the business needs of the application. Lower the threshold for applications to use network services and improve the degree of integration between applications and the network.

[0011] In combination with the first aspect, in a possible implementation of the first aspect, the first request carries an identity identifier associated with the client. Further, the first server determines the first network service according to the identity identifier associated with the client. By carrying the identity identifier associated with the client in the first request, it is convenient for the first server to allocate a suitable network service to the client, thereby improving the user experience.

[0012] Exemplarily, the client-related identity includes: an identity of a first application, an identity of a first user, and / or an identity of a first service, wherein the first application initiates the first service and the first user is a user in the first application.

[0013] In combination with the first aspect, in a possible implementation of the first aspect, the first response also includes any one or more of the following information: identification information of the network service provider of the first network service; type information of the first network service; attribute information of the first network service; authentication service node information, the authentication service node information indicating a network node that provides authentication services for a message requesting the first network service; or authentication information.

[0014] Specifically, the identification information of the network service provider of the first network service, exemplarily, the network service provider may be an operator, and the identification information of the network service provider may be the identity of the operator. For example, the identification information of the network service provider "China Mobile" is "1", the identification information of the network service provider "China Unicom" is "2", and the identification information of the network service provider "China Telecom" is "3"; the type information of the first network service indicates the type of the first network service that the client requests to subscribe to. The type information of the first network service includes but is not limited to: application-aware network (APN), network slicing, segment routing policy (SR policy), flow detection (IFIT), deterministic network (DetNet), virtual private network (VPN) or quality of service (QoS); attribute information of the first network service. The attribute information of the first network service indicates the attributes of the first network service, or the attribute information of the first network service is used to indicate the meaning of the resource information of the first network service. Exemplarily, the attribute information of the first network service indicates the application type applicable to the first network service. For example, the attribute information of the first network service is a video application (or a VR application, or an XR application), which specifically means that the available resources of the first network service are suitable for video applications (or a VR application, or an XR application); authentication service node information, the authentication service node information indicates a network node that provides authentication services for messages requesting the first network service. It should be noted that there are many possible implementations of the network node that provides authentication services (or authentication verification services) in the embodiment of the present application. The network node can be a hardware device (such as a network device) or software, and the embodiment of the present application does not limit this. Exemplarily, the network node includes but is not limited to: a network device, a server, a bare metal, a virtual machine, a container, a network service function chain, or a microservice, etc.; or, authentication information, there are many possible implementations of authentication information, and the embodiment of the present application does not limit this. For example, the authentication information can be a hash value, or a hash operation message authentication code (HMAC) check value, etc. The first response can also include the above-mentioned various information to facilitate the client to request the use of network services and improve the user experience.

[0015] In conjunction with the first aspect, in a possible implementation of the first aspect, the first request is a registration request of the client or a login request of the client. The client can apply for network services in multiple ways to improve the implementation flexibility of the solution.

[0016] In combination with the first aspect, in a possible implementation of the first aspect, the first server obtains the first network service information, including: the first server sends a second request to a second server; the first server receives a second response sent by the second server based on the second request, and the second response carries the first network service information; wherein the second server is a network service provider server.

[0017] In a possible implementation manner, an application server of an application service provider (the application server belongs to the first server) sends a second request to a second server.

[0018] In another possible implementation, a background management platform of an application of an application service provider (the background management platform of the application belongs to the first server) sends a second request to the second server.

[0019] In the embodiment of the present application, the second server is a server related to the network service provider. The first server applies for network service from the second server by sending a second request to the second server. The second server feeds back a second response to the first server based on the second request, and the second response carries the first network service information. The first server obtains the ability to allocate the first network service to the client according to the first network service information carried in the second request.

[0020] In combination with the first aspect, in a possible implementation of the first aspect, the second request carries any one or more of the following information: type information of the first network service, or network service demand information. Exemplarily, the network service demand information includes, but is not limited to: bandwidth, transmission rate, delay, delay jitter, QoS category (class type), Quality of Experience (QoE) score, encryption protection level, integrity protection level, packet loss rate, computing resources, application status or network service status, etc. Specifically, the first server determines the type of network service to be applied for, such as the need to apply for APN service or network slicing service, and the second request carries type information of the network service indicating the APN service or network slicing service. In addition, the second request may carry network service demand information, which refers to the demand information of the first server for the network service. By carrying the type information and / or network service demand information of the first network service in the second request, the second server can allocate more accurate network services to the first server, thereby improving the convenience of using network services and improving user experience.

[0021] In combination with the first aspect, in a possible implementation manner of the first aspect, the first network service information includes any one or more of the following information: identification information of the network service provider of the first network service; type information of the first network service; resource information of the first network service; attribute information of the first network service; parameter information of the first network service; authentication service node information, the authentication service node information indicating a network node that provides authentication services for a message requesting the first network service; or authentication information.

[0022] Specifically, the resource information of the first network service indicates at least one available resource of the first network service. The resource information of the first network service indicates at least one available resource of the first network service, and the resource information of the first network service is identification information of available resources related to the first network service (or resource blocks of the first network service). The resource information of the first network service may be one or more identification information for identifying resources, or a group of address segments for identifying resources, or a start and end range of identification information for identifying resources, or a list of identification information for identifying resources. For ease of understanding, taking the first network service as an example of APN, the resource information of the first network service may be a group of 10 APN identifiers (APN IDs) of application A, indicating that application A can be allocated to 10 users for use. For another example, taking the first network service as an SRv6 network service as an example, the resource identifier of the first network service may be a group of 3 SRv6 binding segment identifiers (binding SIDs) representing gold medal services and a group of 5 SRv6 binding SIDs representing silver medal services. For another example, taking the first network service as network measurement, the resource identifier of the first network service may be 100 flow identifiers (flowID) representing application B, and application B may use these 100 flow identifiers to allocate to 100 application flows that need to enable the network measurement service.

[0023] Optionally, the resource information of the first network service corresponds to a namespace of identification information of a network service provider of the first network service, or the resource information of the first network service corresponds to a namespace of type information of the first network service.

[0024] In combination with the first aspect, in a possible implementation of the first aspect, before the first server determines the first network service corresponding to the client based on the first request sent by the client, the method further includes: the first server obtains a third request sent by the client, and the third request is used to request to subscribe to the first network service. The client can subscribe to the first network service from the first server in advance, so that when the client actually requests to use the first network service, it can conveniently obtain relevant information of the first network service, thereby improving user convenience.

[0025] In combination with the first aspect, in a possible implementation manner of the first aspect, the first network service identifier is a globally unique identifier, or the first network service identifier corresponds to a namespace of type information of the first network service.

[0026] Specifically, the first network service identifier is a globally unique identifier, and the network device or client determines the first network service corresponding to the first network service identifier according to the first network service identifier. For example, the network device or client locally maintains an association relationship between the network service identifier and the network service information, and the network device or client can determine the corresponding network service information from the association relationship according to the network service identifier.

[0027] Exemplarily, the type of network service #1 is APN service, and the network service identifier of network service #1 includes: "100". The meaning of this network service identifier is that the type of network service #1 is APN service, and the instance of network service #1 is the APN service corresponding to identifier 100. The type of network service #2 is network slicing service, and the network service identifier of network service #2 includes: "200". The meaning of this network service identifier is that the type of network service #2 is network slicing service, and the instance of network service #2 is the network slicing service corresponding to identifier 200. The type of network service #3 is network measurement service, and the network service identifier of network service #3 includes: "300". The meaning of this network service identifier is that the type of network service #3 is network measurement service, and the instance of network service #3 is the network measurement service corresponding to identifier 300.

[0028] Regarding the namespace of the first network service identifier corresponding to the type information of the first network service, it can also be understood that the semantics of the first network service identifier is determined by the type information of the first network service. In combination with the type of the network service indicated by the type information of the network service, the network service identifier is used to identify an instance of the network service. The network device or client determines the first network service corresponding to the first network service identifier based on the first network service identifier and the type information of the first network service.

[0029] Exemplarily, the type of network service #1 is APN service, the type information of network service #1 is "1", and the network service identifier is: "100". Combined with the type information of network service #1, the meaning of the network service identifier is that the type of network service #1 is APN service, and the network service identifier is used to identify that the instance of network service #1 is the APN service corresponding to APN ID 100. The type of network service #2 is a network slice service, and the network service identifier of network service #2 includes: "100". Combined with the type information of network service #2, the meaning of the network service identifier is that the type of network service #2 is a network slice service, and the network service identifier is used to identify that the instance of network service #2 is the network slice service corresponding to Slice ID 100.

[0030] In combination with the first aspect, in a possible implementation of the first aspect, the first network service includes any one or more of the following: application-aware network APN, network slicing, segment routing policy SR policy, in-flow detection IFIT, deterministic network DetNet, virtual private network VPN or quality of service QoS.

[0032] In an embodiment of the present application, the first server is an application-related server, or a server related to an application service provider. The client is an application-related client, and the client sends a service-related service message. It should be noted that the service message in the embodiment of the present application may also be an application-related application message, for example, replacing the service message with an application message, which is not limited in the embodiment of the present application. The client in the embodiment of the present application may be a client or server of various applications, including but not limited to: video service applications, such as video conferencing applications, video chat applications, short video applications, or live broadcast applications; audio service applications, such as voice chat applications; extended reality (XR) services, virtual reality (VR) services, augmented reality (AR) services, or mixed reality (MR) services, etc.

[0033] In an embodiment of the present application, a client sends a first request to a first server, and through the first request, requests the first server to use a first network service. Based on the first request, the first server determines the first network service corresponding to the client. Then, the first server may send a first response to the client, and the first response carries the first network service identifier determined by the first server from the resource information of the first network service. After the client obtains the permission to use the first network service, the first service message sent by the client may carry the first network service identifier, and the first network service identifier is used to indicate that the network device provides the first network service for the first service message. The network provides a network service identifier for identifying the network service. After the client obtains the network service identifier, the service message sent by the client may request the corresponding network service by carrying the network service identifier. The network provides an interface between the network service and the network service identifier to provide multiple types of network services to the application, so as to facilitate the application to request network services in a refined manner. The network can provide network services to the application more conveniently to better meet the business needs of the application. Lower the threshold for applications to use network services and improve the degree of integration between applications and networks.

[0034] In combination with the second aspect, in a possible implementation manner of the second aspect, the first response also includes first network service information, and the first network service information includes any one or more of the following information: identification information of the network service provider of the first network service; type information of the first network service; resource information of the first network service, the resource information of the first network service indicates at least one available resource of the first network service; attribute information of the first network service; parameter information of the first network service; authentication service node information, the authentication service node information indicates a network node that provides authentication services for a message requesting the first network service; or authentication information.

[0035] Specifically, the identification information of the network service provider of the first network service, illustratively, the network service provider may be an operator, and the identification information of the network service provider may be the identity of the operator. For example, the identification information of the network service provider "China Mobile" is "1", the identification information of the network service provider "China Unicom" is "2", and the identification information of the network service provider "China Telecom" is "3";

[0036] The type information of the first network service indicates the type of the first network service that the client requests to subscribe to. The type information of the first network service includes, but is not limited to: application-aware network, network slicing, segment routing strategy, flow detection, deterministic network, virtual private network or quality of service; resource information of the first network service, the resource information of the first network service indicates at least one available resource of the first network service. The resource information of the first network service indicates at least one available resource of the first network service, and the resource information of the first network service is the identification information of the available resources related to the first network service (or the resource block of the first network service). The resource information of the first network service may be one or more identification information for identifying resources, or a group of address segments for identifying resources, or the start and end range of identification information for identifying resources, or a list of identification information for identifying resources. For ease of understanding, taking the first network service as an example of APN, the resource information of the first network service may be a group of 10 APN identifiers of application A, indicating that application A can be allocated to 10 users. For another example, taking the first network service as an SRv6 network service as an example, the resource identifier of the first network service may be a group of 3 SRv6 binding segment identifiers representing gold services and a group of 5 SRv6binding SIDs representing silver services. For another example, taking the first network service as network measurement, the resource identifier of the first network service may be 100 flow identifiers (flow IDs) representing application B, which may be used by application B to allocate these 100 flow identifiers to 100 application flows that need to enable the network measurement service; attribute information of the first network service. The attribute information of the first network service indicates the attributes of the first network service, or the attribute information of the first network service is used to indicate the meaning of the resource information of the first network service. Exemplarily, the attribute information of the first network service indicates the application type applicable to the first network service. For example, the attribute information of the first network service is a video application (or a VR application, or an XR application), which specifically means that the available resources of the first network service are applicable to video applications (or VR applications, or XR applications); authentication service node information, the authentication service node information indicates the network node that provides authentication services for the message requesting the first network service. It should be noted that there are multiple possible implementation methods for the network node that provides authentication services (or authentication verification services) in the embodiment of the present application. The network node may be a hardware device (such as a network device) or software, and the embodiment of the present application does not limit this. Exemplarily, the network node includes, but is not limited to: network equipment, servers, bare metal, virtual machines, containers, network service function chains, or microservices, etc.; or, authentication information, there are many possible implementation methods for authentication information, and the embodiments of the present application do not limit this. For example, the authentication information can be a hash value, or a hash operation message authentication code (HMAC) check value, etc.

[0037] In conjunction with the second aspect, in a possible implementation of the second aspect, the first request carries the client-related identity identifier. By carrying the client-related identity identifier in the first request, the first server can allocate appropriate network services to the client, thereby improving user experience.

[0038] Exemplarily, the client-related identity includes: an identity of a first application, an identity of a first user, and / or an identity of a first service, wherein the first application initiates the first service and the first user is a user in the first application.

[0039] In combination with the second aspect, in a possible implementation of the second aspect, the first response also includes multiple network service identifiers, and the multiple network service identifiers include the first network service identifier; the method also includes: the client determines the corresponding multiple network services based on the multiple network service identifiers, and the multiple network services include the first network service; the client determines one or more network services used by the first business message based on the multiple network services, wherein the one or more network services used by the first business message include the first network service.

[0040] Optionally, the client may also carry multiple network service identifiers included in the first response in the first service message. The network device receiving the first service message selects the network service provided by the network device for the first service message based on the multiple network service identifiers and the identification information of the network service providers of the multiple network service identifiers.

[0042] In one example, when the first response includes multiple network service identifiers corresponding to multiple network services of the same type, the client may randomly select one or more network services from the multiple network services of the same type, or the client may select one or more network services with higher priorities based on the priorities of the multiple network services of the same type, or the client may select one or more network services from the multiple network services of the same type based on local policies, or the client may select one or more network services from the multiple network services of the same type based on an agreement, where the agreement refers to an agreement between a network service provider and an application service provider, and the agreement may be configured in the client or network device.

[0043] In another example, when the multiple network service identifiers included in the first response correspond to multiple different types of network services, the client determines whether the functions of the multiple different types of network services overlap or conflict. For example, when the multiple different types of network services include: APN service and network slice service, the functions of the APN service and the network slice service conflict. According to the local policy, priority or agreement of the client, it is determined that the APN service takes precedence over the network slice service, and the client selects the APN service from the multiple different types of network services.

Exemplarily, the state information of the first application includes the working state of the first application and / or the user experience state of the first application, for example, the bandwidth occupancy rate of the first application or the delay value of the first application. Exemplarily, the status information of the first user includes but is not limited to: the delay value of the first user, the packet loss rate of the first user, the bandwidth usage of the first user, the computing resource usage of the first user, whether the operation event of the first user occurs, the number of operations of the first user, the usage time of the first user, or the viewing time of the first user. Exemplarily, the status information of the first service includes but is not limited to: the delay value of the first service, the packet loss rate of the first service, the bandwidth usage of the first service, or the computing resource usage of the first service.

[0049] Specifically, the third request carries relevant information of the client, such as an identity identifier related to the client or attribute information of the client, etc. The embodiment of the present application does not limit the relevant information of the client. Furthermore, the identity identifier related to the client includes: an identity identifier of a first application, an identity identifier of a first user, and / or an identity identifier of a first service, wherein the first application initiates the first service and the first user is a user in the first application.

[0050] In a possible implementation, the third request also includes type information and / or network service demand information of the first network service. By carrying the type information of the first network service in the third request, the type of the first network service that the client requests to subscribe to is indicated. The type information of the first network service includes, but is not limited to: application-aware network, network slicing, segment routing strategy, flow detection, deterministic network, virtual private network, or quality of service.

[0058] In an embodiment of the present application, after the first server obtains the first network service information, it obtains the ability to allocate the first network service to the client. Based on the first request sent by the client, the first server determines the first network service corresponding to the client. Then, the first server can send a first response to the client, and the first response carries the first network service identifier determined by the first server from the resource information of the first network service. After the client obtains the permission to use the first network service, the first business message sent by the client can carry the first network service identifier, and the first network service identifier is used to indicate that the network device provides the first network service for the first business message. The network provides a network service identifier for identifying the network service. After the client obtains the network service identifier, the business message sent by the client can request the corresponding network service by carrying the network service identifier. The network provides an interface between the network service and the network service identifier to provide multiple types of network services to the application, which facilitates the application to request network services in a refined manner. The network can provide network services to the application more conveniently to better meet the business needs of the application. Lower the threshold for applications to use network services and improve the degree of integration between applications and networks.

[0059] In conjunction with the third aspect, in a possible implementation of the third aspect, the first request carries the identity identifier associated with the client. By carrying the identity identifier associated with the client in the first request, it is convenient for the first server to allocate appropriate network services to the client, thereby improving user experience.

[0060] Exemplarily, the client-related identity includes: an identity of a first application, an identity of a first user, and / or an identity of a first service, wherein the first application initiates the first service and the first user is a user in the first application.

[0061] In combination with the third aspect, in a possible implementation of the third aspect, the business processing system also includes a second server, which is a network service provider server; the first server obtains the first network service information, including: the first server sends a second request to the second server; based on the second request sent by the first server, the second server sends a second response to the first server, and the second response carries the first network service information; the first server obtains the first network service information according to the second response.

[0062] In a possible implementation, based on the second request sent by the first server, the second server determines the first network service allocated to the first server; the second server sends a second response to the first server, and the second response carries the first network service information.

[0063] In a possible implementation manner, an application server of an application service provider (the application server belongs to the first server) sends a second request to a second server.

[0064] In another possible implementation, a background management platform of an application of an application service provider (the background management platform of the application belongs to the first server) sends a second request to the second server.

[0065] In the embodiment of the present application, the second server is a server related to the network service provider. The first server applies for network service from the second server by sending a second request to the second server. The second server feeds back a second response to the first server based on the second request, and the second response carries the first network service information. The first server obtains the ability to allocate the first network service to the client according to the first network service information carried in the second request.

[0066] In combination with the third aspect, in a possible implementation of the third aspect, the second request carries any one or more of the following information: type information of the first network service, or network service demand information. Exemplarily, the network service demand information includes, but is not limited to: bandwidth, transmission rate, delay, delay jitter, QoS category, quality of experience score, encryption protection level, integrity protection level, packet loss rate, computing resources, application status or network service status, etc. Specifically, the first server determines the type of network service that needs to be applied for, such as the need to apply for APN service or network slicing service, and the second request carries type information of the network service indicating the APN service or network slicing service. In addition, the second request may carry network service demand information, which refers to the demand information of the first server for the network service. By carrying the type information and / or network service demand information of the first network service in the second request, the second server can allocate more accurate network services to the first server, thereby improving the convenience of using network services and improving user experience.

[0067] In conjunction with the third aspect, in a possible implementation of the third aspect, before the first server determines the first network service corresponding to the client based on the first request sent by the client, the system further includes: the client sends a third request to the first server, and the third request is used to request to subscribe to the first network service. The client can subscribe to the first network service from the first server in advance, so that when the client actually requests to use the first network service, it can conveniently obtain relevant information of the first network service, thereby improving user convenience.

[0068] In combination with the third aspect, in a possible implementation of the third aspect, the first response also includes multiple network service identifiers, and the multiple network service identifiers include the first network service identifier; the system also includes: the client determines the corresponding multiple network services based on the multiple network service identifiers, and the multiple network services include the first network service; the client determines one or more network services used by the first business message based on the multiple network services, wherein the one or more network services used by the first business message include the first network service.

[0069] Optionally, the client may also carry multiple network service identifiers included in the first response in the first service message. The network device receiving the first service message selects the network service provided by the network device for the first service message based on the multiple network service identifiers and the identification information of the network service providers of the multiple network service identifiers.

[0070] In combination with the third aspect, in a possible implementation of the third aspect, the client determines one or more network services used by the first business message based on the multiple network services, including: the client determines one or more network services used by the first business message from the multiple network services based on the priorities and / or local policies of the multiple network services.

[0071] In one example, when the first response includes multiple network service identifiers corresponding to multiple network services of the same type, the client may randomly select one or more network services from the multiple network services of the same type, or the client may select one or more network services with higher priorities based on the priorities of the multiple network services of the same type, or the client may select one or more network services from the multiple network services of the same type based on local policies, or the client may select one or more network services from the multiple network services of the same type based on an agreement, where the agreement refers to an agreement between a network service provider and an application service provider, and the agreement may be configured in the client or network device.

[0072] In another example, when the multiple network service identifiers included in the first response correspond to multiple different types of network services, the client determines whether the functions of the multiple different types of network services overlap or conflict. For example, when the multiple different types of network services include: APN service and network slice service, the functions of the APN service and the network slice service conflict. According to the local policy, priority or agreement of the client, it is determined that the APN service takes precedence over the network slice service, and the client selects the APN service from the multiple different types of network services.

[0077] Specifically, after receiving the first business message, the first network device determines the network service provider of the first network service corresponding to the first network device based on the identification information of the network service provider of the first network service included in the first business message and the identification information of the network service domain to which the first network device belongs. In other words, the first network device supports the provision of the first network service. Therefore, based on the network service provider of the first network service corresponding to the first network device, the first network device can provide the first network service for the first business message based on the first network service identifier carried by the first business message. Through the interface between the network service identifier and the network service, the network device realizes the provision of network services to the business message, thereby improving the convenience of using the network service.

[0078] It should be noted that a network service provider can set up multiple network service domains (or multiple network domains), and each network service domain can set up a corresponding network service provider's identification information. Therefore, a network service provider can correspond to multiple network service provider's identification information, and each network service provider's identification information corresponds to a network service domain set up by the network service provider.

[0079] In combination with the third aspect, in a possible implementation of the third aspect, the system also includes: the first network device obtains the identification information and / or the authentication information of the network service provider of the first network service carried by the first business message; the first network device performs authentication verification on the first business message based on the identification information and / or the authentication information of the network service provider of the first network service carried by the first business message; if the first business message passes the authentication verification, the first network device provides the first network service for the first business message.

[0080] In a possible implementation, the first network device performs authentication verification on the first business message based on the first network service information, including: the first network device receives network service configuration information sent by a server, the network service configuration information includes network service information corresponding to at least one network service; the first network device matches the identification information of the network service provider of the first network service included in the first network service information with the identification information of the network service domain in the network service configuration information, the identification information of the network service domain in the network service configuration information indicates the network service provider corresponding to the first network device; if the match is successful, the first network device determines that the first business message passes the authentication verification.

For example, when the first network service is an SRv6 service, the first network device encapsulates a segment routing extension header (SegmentRouting Header, SRH) for the first business message. The first network device adds the first network service information and / or the client-related attribute information to the SRH to obtain the first business message after adding.

[0086] In combination with the third aspect, in a possible implementation manner of the third aspect, the first message header is a message header of a network layer of the first service message, or the first message header is a message header of a transport layer of the first service message.

[0087] In combination with the third aspect, in a possible implementation of the third aspect, the first network device adds the first network service information to the first business message again to obtain the added first business message, including: the first network device adds the first network service information to the payload of the first business message to obtain the added first business message.

It also includes the future sixth generation (6th-generation, 6G) mobile communication network.

[0210] First, the business processing system proposed in the embodiment of the present application is introduced. In a possible implementation method, please refer to Figure 1 , Figure 1A schematic diagram of a business processing system proposed in an embodiment of the present application. A business processing system proposed in an embodiment of the present application includes: a first server, a second server, a client, and a first network device, wherein the first server is an application-related server, or a server related to an application service provider, and the application service provider provides application-related services; the second server is a server related to a network service provider that provides network services; the client is an application-related client, and the client sends business-related business messages; the first network device provides network services for business messages. It should be noted that the business message in the embodiment of the present application may also be an application-related application message, for example, replacing the business message with an application message, and the embodiment of the present application does not limit this.

[0211] For example, the client may be an application client, the first server belongs to an application service provider, and the second server belongs to a network service provider. Further, the network service provider in the embodiment of the present application may have multiple possible implementation entities, including but not limited to: a telecommunications operator, an alliance of telecommunications operators, a maintenance organization of a network service identifier, a management organization of a network service identifier, or an allocation organization of a network service identifier.

[0212] Specifically, the first server applies for a network service from the second server, and carries relevant information such as the type information of the network service and the network service demand information when applying for the network service from the second server. The first server requests the second server to allocate resources for the network service. Then, after the second server determines the network service to be allocated to the first server based on the application of the first server, the second server sends network service information related to the network service to the first server.

[0213] After receiving the request from the client, the first server allocates a network service identifier of the network service to the client according to the request from the client and the network service information obtained from the second server. The service message sent by the first server carries the network service identifier.

[0214] The first network device refers to a network device that provides network services in a network service domain (NSD) (or network domain). After the first network device obtains network service configuration information related to the network service from the second server, when the first network device receives a service message carrying a network service identifier corresponding to the network service, the first network device provides the network service according to the network service identifier. The service message is forwarded between one or more first network devices in the network service domain, and one or more network devices in the network service domain provide network services for the service message.

[0215] In yet another possible implementation, see Figure 2 , Figure 2 A schematic diagram of another business processing system proposed for an embodiment of the present application. The first server (application service provider) can also be divided into an application server and an application management platform according to its purpose, wherein the application server is used to provide application-related services, and the application management platform is used to manage one or more application servers. The first server applies for network services from the second server, specifically, the application management platform (first server) applies for network services from the second server. When the application management platform applies for network services, the application management platform distributes the acquired network service information to the corresponding application server, and the application management platform sends the network service information to the application server. After receiving the request from the client, the application server assigns a network service identifier to the client according to the network service information.

[0216] In another possible implementation, after the application management platform applies for the network service, the application management platform allocates the network service identifier in the obtained network service information to the application server, and the application management platform sends the network service identifier to the application server. After receiving the request from the client, the application server allocates the network service identifier to the client.

[0217] Exemplarily, the client in the embodiments of the present application can be a client or server of various applications, including but not limited to: video service applications, such as video conferencing applications, video chat applications, short video applications, or live broadcast applications; audio service applications, such as voice chat applications; extended reality (XR) services, virtual reality (VR) services, augmented reality (AR) services, or mixed reality (MR) services, etc.

Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and fully or partially independent of smartphones, such as smart watches or smart glasses, as well as devices that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets and smart jewelry for vital sign monitoring.

[0225] Exemplarily, in an embodiment of the present application, the first server, the second server, the client, and / or the first network device can be interconnected and networked through any one or more of the following methods: wireless fidelity (WIFI), Bluetooth, Bluetooth Low Energy (BLE), ultra-wideband, ZigBee, radio frequency identification (RFID), fourth-generation mobile communication technology (4G), fifth-generation mobile communication technology (5G), sixth-generation mobile communication technology (6G), long-range radio (LoRa), Internet of Things (IoT) or narrowband Internet of Things (NB-IoT), etc.

[0226] Next, the embodiments of the present application are described in conjunction with the accompanying drawings. Figure 3 , Figure 3 The following is a flow chart of a service processing method according to an embodiment of the present application. A service processing method according to an embodiment of the present application includes:

[0227] S0. The client sends a third request to the first server, where the third request is used to request to subscribe to the first network service.

[0228] Step S0 is an optional step.

[0229] In step S0, the client can subscribe to a network service from the first server. Taking the subscription to the first network service as an example: the client sends a third request to the first server, and the third request is used to request subscription to the first network service. The third request carries relevant information of the client, such as an identity identifier related to the client or attribute information of the client, etc. The embodiment of the present application does not limit the relevant information of the client. Furthermore, the identity identifier related to the client includes: an identity identifier of the first application, an identity identifier of the first user, and / or an identity identifier of the first service, wherein the first application initiates the first service, and the first user is a user in the first application. The identity identifier can be an identity ID, address information, or a port number, etc., which is not limited in the embodiment of the present application.

[0230] In one possible implementation, the third request also includes type information of the first network service and / or network service demand information. By carrying the type information of the first network service in the third request, the type of the first network service that the client requests to subscribe to is indicated. The type information of the first network service includes, but is not limited to: Application-aware Networking (APN), network slicing, segment routing policy (SR policy), In-situ Flow Information Telemetry (IFIT), Deterministic Networking (DetNet), Virtual Private Network (VPN), or Quality of Service (QoS).

[0231] The network service demand information in step S0 is used to indicate the performance demand or business demand of the client for the first network service requested for subscription, such as what performance indicators or business indicators the first network service requested for subscription needs to meet. For example, the network service demand information includes but is not limited to: bandwidth, transmission rate, delay, delay jitter, QoS class type, Quality of Experience (QoE) score, encryption protection level, integrity protection level, packet loss rate, computing resources, application status or network service status, etc.

[0232] Regarding the first network service, the embodiment of the present application does not limit the specific network service type of the first network service. The first network service can be one network service or multiple network services. The first network service includes any one or more of the following: application-aware network APN, network slicing, segment routing policy SR policy, flow detection IFIT, deterministic network DetNet, virtual private network VPN or quality of service QoS. It should be noted that the first network service can also be other network services, which is not limited by the embodiment of the present application.

[0233] For example, the first network service that the client requests to subscribe to is APN, and the first network service needs to meet the requirements of latency less than 10 milliseconds (ms), and bandwidth greater than 300 megabits per second (mbps). Then the type information of the first network service carried in the third request is APN, and the network service requirement information is: latency less than 10 milliseconds, and bandwidth greater than 300 mbps.

[0234] Correspondingly, after the first server allocates the subscribed first network service to the client according to the third request, the first server associates and stores the relevant information of the client with the relevant information of the first network service subscribed by the client. For example, as shown in Table 1:

[0235] Table 1

[0236]

[0237] S1. A first server obtains first network service information, where the first network service information includes type information of the first network service and resource information of the first network service.

[0238] In step S1, the first server may obtain the relevant information of the first network service in a variety of ways. In the embodiment of the present application, for ease of description, the relevant information of the first network service is referred to as first network service information.

[0239] In a possible implementation, the first server (application server) applies to the second server for a specific type of network service, and the first server provides the type information of the required network service and the network service demand information when applying to the second server. Taking the example of the first server needing the first network service, when the first server applies to the second server for the first network service, it carries the type information of the first network service and the network service demand information related to the first network service. Then, the second server allocates the first network service to the first server according to the application. Specifically, the second server sends the first network service information related to the first network service to the first server.

[0240] In another possible implementation, the first server is composed of an application server and a background management platform for managing the application server, the background management platform applies for network services from the second server, and the corresponding second server sends the first network service information to the background management platform. The background management platform sends the first network service information to the application server.

[0241] The first network service information includes any one or more of the following: the first network service information includes any one or more of the following information: identification information of a network service provider of the first network service, resource information of the first network service, type information of the first network service, attribute information of the first network service, parameter information of the first network service, authentication service node information, or authentication information. Each of the following is described below.

[0242] 1. Identification information of the network service provider of the first network service. Exemplarily, the network service provider may be an operator, and the identification information of the network service provider may be the identity of the operator. For example, the identification information of the network service provider "China Mobile" is "1", the identification information of the network service provider "China Unicom" is "2", and the identification information of the network service provider "China Telecom" is "3".

[0243] 2. Type information of the first network service, indicating the type of the first network service that the client requests to subscribe to. For details about the type information of the first network service, see the aforementioned step S0, which will not be described in detail here.

[0244] 3. The resource information of the first network service indicates at least one available resource of the first network service, and the resource information of the first network service is identification information of the available resources related to the first network service (or the resource block of the first network service). The resource information of the first network service may be one or more identification information for identifying resources, or a group of address segments for identifying resources, or the start and end ranges of identification information for identifying resources, or a list of identification information for identifying resources, or an identification information block for identifying resources. For ease of understanding, taking the first network service as APN as an example, the resource information of the first network service may be a group of 10 APN identifiers (APN IDs) of application A, indicating that application A can be allocated to 10 users for use. For another example, taking the first network service as an SRv6 network service as an example, the resource identifier of the first network service may be a group of 3 SRv6 binding segment identifiers (binding SIDs) representing gold medal services and a group of 5 SRv6 binding SIDs representing silver medal services. For another example, taking the first network service as network measurement, the resource identifier of the first network service may be 100 flow IDs representing application B, and application B may use these 100 flow IDs to allocate to 100 application flows that need to enable the network measurement service.

[0245] 4. Attribute information of the first network service. Specifically, the attribute information of the first network service indicates the attributes of the first network service, or the attribute information of the first network service is used to represent the meaning of resource information of the first network service.

[0246] Exemplarily, the attribute information of the first network service indicates the application type applicable to the first network service. For example, the attribute information of the first network service is a video application (or a VR application, or an XR application), which specifically means that the available resources of the first network service are applicable to video applications (or VR applications, or XR applications). In combination with the attribute information of the first network service, it is determined that the available resources indicated by the resource information of the first network service are allocated to video services (or VR applications, or XR applications). For example, taking the first network service as APN as an example, the resource information of the first network service is "APN ID 1~APN ID 100", which indicates that the available resources of the first network service include resources corresponding to APN ID 1~APNID 100, and the attribute information of the first network service is a video service type. In combination with the attribute information of the first network service, the available resources "APN ID1~APN ID100" of the first network service can be allocated to video services.

[0247] In another example, the attribute information of the first network service is subdivided into security groups, specifically meaning that the available resources of the first network service are applicable to the services (or users) under the security group. In combination with the attribute information of the first network service, it is determined that the available resources indicated by the resource information of the first network service are allocated to the services (or users) belonging to the security group.

[0248] In another example, the attribute information of the first network service is a video data segmentation, which specifically means that the service (or user) to which the available resources of the first network service are applicable is the service (or user) corresponding to the video data segmentation. For example, the attribute information of the first network service is 1080P video data, and the available resources indicated by the resource information of the first network service are determined in combination with the attribute information of the first network service to be allocated to the service (or user) requiring the use of 1080P video data. For another example, the attribute information of the first network service is the key frame data of the video, and the key frame data may be I frame data, and the available resources of the first network service are determined in combination with the attribute information of the first network service to be allocated to the service message carrying the key frame data. The first network device needs to provide the first network service to the service message carrying the key frame data. For another example, the attribute information of the first network service is the non-key frame data of the video, and the non-key frame data may be P frame data or B frame data, and the available resources of the first network service are determined in combination with the attribute information of the first network service to be allocated to the service message carrying the non-key frame data. The first network device needs to provide the first network service to the service message carrying the non-key frame data.

[0249] Exemplarily, a possible scenario is as follows: the client sends a service message #I carrying a key frame, and the service message #I carries a network service identifier #1. The first network device provides the service message #I with network service #1 corresponding to the network service identifier #1 based on the network service identifier #1 carried by the service message #I. The client sends a service message #P carrying a non-key frame, and the service message #P carries a network service identifier #2. The first network device provides the service message #P with network service #2 corresponding to the network service identifier #2 based on the network service identifier #2 carried by the service message #P. This enables different network services to be provided for different video frame data of the video service.

[0250] In another example, the attribute information of the first network service includes but is not limited to: low latency, high bandwidth, and / or low packet loss, etc. The specific meaning is that the available resources of the first network service meet the requirements of low latency, high bandwidth and / or low packet loss. For example, the first network service is SRv6 policy, and the resource information of the first network service is "Binding SID 200~Binding SID300". According to the attribute information of the first network service, it can be determined that the available resources of the first network service are low-latency paths that meet the low latency requirements, and according to the attribute information of the first network service, it is determined that the path corresponding to the above-mentioned Binding SID 200~Binding SID 300 is a low-latency path.

[0251] In another example, the attribute information of the first network service is: high-bandwidth link, video reassurance (also known as video importance guarantee), or industrial manufacturing. For example, the first network service is network slicing, the attribute information of the first network service is video reassurance, and the resource information of the first network service is network slice ID (slice ID) 1 to network slice ID 10. According to the attribute information of the first network service, it is determined that the available resources of the first network service (for example, the network slice corresponding to network slice ID1 to the network slice corresponding to network slice ID10) can be allocated to the service requiring video reassurance, and the available resources of the network service provide network slices that meet the video reassurance requirements.

[0252] In another example, the attribute information of the first network service is: hop-by-hop measurement or end-to-end measurement. For example, the first network service is network measurement, the attribute information of the first network service is hop-by-hop measurement, and the resource information of the first network service is flow ID 200. According to the attribute information of the first network service, it is determined that the available resources of the first network service (flow with flow ID 200) can be allocated to the service requiring hop-by-hop measurement, and the available resources of the network service provide flows that support hop-by-hop measurement.

[0253] 5. Parameter information of the first network service The parameter information of the first network service refers to parameters related to the first network service. The parameter information of the first network service may be different depending on the first network service. The embodiment of the present application does not limit the parameter information of the first network service.

[0254] In one example, when the first network service is APN, the parameter information of the first network service includes but is not limited to: the SRv6 Policy color mapped to the APN ID, the ID of the network slice mapped to the APN ID, the IFIT instance mapped to the APN ID, or the QoS queue mapped to the APN ID.

[0255] In another example, when the first network service is an SRv6 policy, the parameter information of the first network service includes but is not limited to: a SID list (SID list) after the binding SID is expanded.

[0256] In another example, when the first network service is a network slice, parameter information of the first network service includes but is not limited to: a Flexible Ethernet (Flex Ethernet, FlexE) port, a channelized sub-port, or an index of a Flexible Ethernet channel (FlexE-channel).

[0257] In another example, when the first network service is network measurement, the parameter information of the first network service includes but is not limited to: the statistical period of network measurement, the type of network measurement, or the precision of network measurement. For example, the type of network measurement includes but is not limited to: measuring delay, measuring packet loss rate, or measuring transmission rate. For another example, the precision of network measurement includes but is not limited to: end-to-end measurement, or hop-by-hop measurement.

[0258] 6. Authentication service node information, the authentication service node information indicates the network node that provides authentication service for the message requesting the first network service, such as the ID information of the network node, or the Internet protocol (IP) address of the network node, or the port number of the network node, or the SRv6 SID that identifies the network node providing the authentication service function.

[0259] It should be noted that there are many possible implementations of the network node that provides authentication services (or authentication verification services) in the embodiments of the present application. The network node can be a hardware device (such as a network device) or software, and the embodiments of the present application do not limit this. Exemplarily, the network node includes but is not limited to: network devices, servers, bare metal, virtual machines, containers, network service function chains, or microservices, etc.

[0260] In one possible implementation, the network node may be a network device. The network device may be an edge node in a network service domain. After a service message is sent from a client, the network device responsible for forwarding the service message determines the edge node that provides authentication verification services based on the authentication service node information carried by the service message. Then, the network device forwards the service message to the edge node that provides authentication verification services, and the edge node performs authentication verification on the service message. It should be noted that after a service message is sent from a client, it may also be sent directly to an edge node.

[0261] Regarding the edge node, it can be a head node that provides network services in the network service domain, it can also be a tail node that provides network services in the network service domain, or it can be other nodes that do not provide network services in the network service domain. The embodiments of the present application do not limit this.

[0262] 7. Authentication information. The authentication information is used to authenticate and verify the message requesting the first network service. There are many possible implementations of the authentication information, which are not limited in the embodiments of the present application. For example, the authentication information may be a hash value, or a hash-based message authentication code (HMAC) check value, etc.

[0263] After the first server obtains the first network service information, the first server obtains the ability to allocate the first network service to the client, and the process goes to step S2.

[0264] S2. The first server receives a first request sent by the client.

[0265] In step S2, the first server receives a first request sent by the client. The first request may be a registration request sent by the client to the first server, or a login request sent by the client to the first server. It is understandable that the first request may also be a request by the client to apply for a first network service, which is not limited in the present embodiment of the application.

[0266] Furthermore, the first request carries relevant information of the client, such as an identity identifier related to the client.

[0267] S3. Based on the first request, the first server determines a first network service corresponding to the client.

[0268] In step S3, based on the first request, the first server determines a first network service corresponding to the client.

[0269] The specific process is as follows: the first server determines the first network service corresponding to the client based on the client-related identity carried in the first request. For example, the first network service that the client requests to subscribe to is determined based on the client-related identity. After the first server determines the first network service that the client requests to subscribe to, the first server determines one or more resources allocated to the client from one or more available resources indicated by the resource information of the first network service. Specifically, the first server determines the first network service identifier from the resource information of the first network service, and then allocates the first network service identifier to the client. In other words, the resource information of the first network service includes one or more first network service identifiers related to the first network service, and the first server determines the first network service identifier corresponding to the client from the resource information of the first network service based on the first request.

[0270] In one example, the resource information of the first network service includes ID 200 to ID 300, totaling 100 IDs. The 100 IDs respectively indicate 100 instances of the first network service. The first server allocates one of the 100 instances to the client based on the first request. The first server determines one ID from the 100 IDs, for example, ID 50, and then allocates ID 50 to the client as the first network service identifier.

[0271] In one example, application A (e.g., first server A) purchases 1,000 network guarantee resources from network service provider B (e.g., through the third request of step S0). The network service provider allocates an APN service to application A. The resource information of the APN service includes 1,000 available APN IDs from APN ID 1 to APN ID 1000. The APN service is used to implement network guarantee. When user C (e.g., client C) purchases network guarantee resources from application A, application A allocates any APN ID from APN ID 1 to APN ID 1000 and related network service information to user C. For example, application A allocates the APN service corresponding to APNID 50 and the network service information related to APN ID 50 to user C, so as to provide network guarantee corresponding to the APN service (APNID 50) to user C.

[0272] Optionally, based on the first request, the first server may also determine multiple network services corresponding to the client, and the multiple network services include the first network service. The multiple network services may be multiple network services of the same type, for example, the multiple network services include: APN#1, APN#2 and APN#3; the multiple network services may also be multiple network services of different types, for example, the multiple network services include: APN#1 and network measurement. The multiple network services may be network services provided by different network service providers, for example, the multiple network services include: network service #1 and network service #2, the network service provider of network service #1 is operator A, and the network service provider of network service #2 is operator B. The multiple network services may be network services provided by the same network service provider, for example, the multiple network services include: network service #1 and network service #2, the network service provider of network service #1 is operator A, and the network service provider of network service #2 is operator A.

[0273] S4. The first server sends a first response to the client, where the first response carries a first network service identifier determined based on the resource information of the first network service.

[0274] In step S4, after the first server determines the first network service corresponding to the client, the first server sends a first response to the client, where the first response carries a first network service identifier determined based on resource information of the first network service.

[0275] Exemplarily, if the first request is a registration request, the first response is a registration success response. In another example, if the first request is a login request, the first response is a login success response.

[0276] Optionally, in addition to carrying the first network service identifier, the first response may also carry first network service information related to the first network service. For example, the first response may also include any one or more of the following information: identification information of the network service provider of the first network service, type information of the first network service, attribute information of the first network service, authentication service node information, the authentication service node information indicating a network node that provides authentication services for a message requesting the first network service, or authentication information.

[0277] Optionally, after the first server determines the multiple network services corresponding to the client, the first response sent by the first server to the client may carry multiple network service identifiers, and the multiple network service identifiers correspond to the multiple network services respectively.

[0278] Regarding the first network service identifier, there are multiple possible implementations, such as any one or more of the following methods 1 and 2.

[0279] Mode 1: The first network service identifier corresponds to a namespace of the type information of the first network service. The semantics of the first network service identifier is determined by the type information of the first network service. In combination with the type of the network service indicated by the type information of the network service, the network service identifier is used to identify an instance of the network service. The network device or client determines the first network service corresponding to the first network service identifier based on the first network service identifier and the type information of the first network service.

[0280] Exemplarily, the type of network service #1 is APN service, the type information of network service #1 is "1", and the network service identifier is: "100". Combined with the type information of network service #1, the meaning of the network service identifier is that the type of network service #1 is APN service, and the network service identifier is used to identify that the instance of network service #1 is the APN service corresponding to APN ID 100. The type of network service #2 is a network slice service, and the network service identifier of network service #2 includes: "100". Combined with the type information of network service #2, the meaning of the network service identifier is that the type of network service #2 is a network slice service, and the network service identifier is used to identify that the instance of network service #2 is the network slice service corresponding to Slice ID 100.

[0281] As can be seen from the above example, the semantics of the network service identifier "100" is determined by the type information of the network service, and the network service identifier corresponds to the namespace of the type information of the network service. When the type information of the network service is "1", the network service indicated by the type information of the network service is an APN service. According to the type information of the network service, the meaning of the network service identifier "100" is the APN service corresponding to APN ID 100. When the type information of the network service is "2", the network service indicated by the type information of the network service is a network slice service. According to the type information of the network service, the meaning of the network service identifier "100" is the network slice service corresponding to network slice ID 100.

[0282] Mode 2: The first network service identifier is a globally unique identifier. Specifically, the network device or client determines the first network service corresponding to the first network service identifier based on the first network service identifier. For example, the network device or client locally maintains the association relationship between the network service identifier and the network service information, and the network device or client can determine the corresponding network service information from the association relationship based on the network service identifier.

[0283] Exemplarily, the type of network service #1 is APN service, and the network service identifier of network service #1 includes: "100". The meaning of this network service identifier is that the type of network service #1 is APN service, and the instance of network service #1 is the APN service corresponding to identifier 100. The type of network service #2 is network slicing service, and the network service identifier of network service #2 includes: "200". The meaning of this network service identifier is that the type of network service #2 is network slicing service, and the instance of network service #2 is the network slicing service corresponding to identifier 200. The type of network service #3 is network measurement service, and the network service identifier of network service #3 includes: "300". The meaning of this network service identifier is that the type of network service #3 is network measurement service, and the instance of network service #3 is the network measurement service corresponding to identifier 300.

[0284] In another possible implementation, the first network service identifier indicates the type of the first network service. Exemplarily, the network service identifier includes: a first field and a second field, wherein the first field indicates the type of the network service, and the semantics of the second field is determined by the type of the network service. In combination with the type of network service indicated by the first field, the second field identifies an instance of the network service. In other words, the second field corresponds to the namespace of the first field. The first field can be an enumeration value, for example, when the first field is "1", it represents the APN service, when the first field is "2", it represents the network slicing service, when the first field is "3", it represents the network measurement service, and so on. The second field may also be referred to as an opaque ID.

[0285] Exemplarily, the type of network service #1 is APN service, and the network service identifier of network service #1 includes: "1:100". The meaning of the first field "1" in the network service identifier is: the type of network service #1 is APN service; the meaning of the second field "100" in the network service identifier is: the instance of network service #1 is the APN service corresponding to APN ID 100. The type of network service #2 is network slicing service, and the network service identifier of network service #2 includes: "2:100". The meaning of the first field "2" in the network service identifier is: the type of network service #2 is network slicing service; the meaning of the second field "100" in the network service identifier is: the instance of network service #2 is the network slicing service corresponding to Slice ID 100.

[0286] It should be noted that, since the first network service identifier belongs to the resource information of the first network service, the resource information of the first network service corresponds to the first network service identifier, and there are also multiple implementation methods. Regarding the resource information of the first network service, there are multiple possible implementation methods, such as any one or more of the following methods 3 to 4.

[0287] Mode 3: First network service identifier As in the implementation of Mode 1 above, the resource information of the first network service may be a group of first network service identifiers.

[0288] In one example, the type information of network service #1 is "APN", and the resource information of network service #1 includes: "100-200". Combined with the type information of network service #1, the resource information of network service #1 means that the type of network service #1 is APN service, and the available resources of network service #1 are APN services corresponding to APN ID 100-APN ID 200.

[0289] In another example, the type information of network service #2 is "network slice service", and the resource information of network service #2 includes: "100-200". Combined with the type information of network service #2, the resource information of network service #2 means that the available resources of network service #2 are the network slice services corresponding to network slice ID 100-network slice ID 200.

[0290] As can be seen from the above example, the semantics of the resource information of the first network service is determined by the type information of the first network service. When the type information of the first network service is "1", the type information of the first network service indicates that the first network service is an APN service. According to the type information of the first network service, the meaning of the resource information "100-200" of the first network service is the APN service corresponding to APN ID 100-APN ID 200. When the type information of the first network service is "2", the type information of the first network service indicates that the first network service is a network slice service. According to the type information of the first network service, the meaning of the resource information "100-200" of the first network service is the network slice service corresponding to network slice ID 100-network slice ID 200.

[0291] Mode 4: First Network Service Identifier As in the implementation mode of Mode 2 above, the network device or the client determines the first network service corresponding to the first network service identifier according to the first network service identifier.

[0292] In one example, the resource information of network service #1 includes: “1-100”. The resource information of network service #1 means that the type of network service #1 is APN service, and the available resources of network service #1 are APN services corresponding to identifiers 1-100.

[0293] In another example, the resource information of network service #2 includes: "200-300". The resource information of network service #2 means that the available resources of network service #2 are the network slice services corresponding to identifiers 200-300.

[0294] S5. The client sends a first service message, where the first service message carries a first network service identifier, and the first network service identifier is used to instruct the network device to provide a first network service.

[0295] In step S5, after receiving the first response, the client determines the first network service that the client can request to use according to the first network service identifier carried in the first response. Then, the first service message sent by the client may carry the first network service identifier, which is used to indicate that the network device provides the first network service.

[0296] Optionally, if the first response further includes multiple network service identifiers, the multiple network service identifiers include the first network service identifier. The client may determine the corresponding multiple network services based on the multiple network service identifiers. The client determines one or more network services used by the first business message based on the multiple network services, wherein the one or more network services used by the first business message include the first network service.

[0297] In one example, when the first response includes multiple network service identifiers corresponding to multiple network services of the same type, the client may randomly select one or more network services from the multiple network services of the same type, or the client may select one or more network services with higher priorities based on the priorities of the multiple network services of the same type, or the client may select one or more network services from the multiple network services of the same type based on local policies, or the client may select one or more network services from the multiple network services of the same type based on an agreement, where the agreement refers to an agreement between a network service provider and an application service provider, and the agreement may be configured in the client or network device.

[0298] In another example, when the multiple network service identifiers included in the first response correspond to multiple different types of network services, the client determines whether the functions of the multiple different types of network services overlap or conflict. For example, when the multiple different types of network services include: APN service and network slice service, the functions of the APN service and the network slice service conflict. According to the local policy, priority or agreement of the client, it is determined that the APN service takes precedence over the network slice service, and the client selects the APN service from the multiple different types of network services.

[0299] Optionally, the client may also carry the multiple network service identifiers included in the first response in the first business message. The network device that receives the first business message selects the network service provided by the network device for the first business message based on the multiple network service identifiers and the identification information of the network service provider of the multiple network service identifiers. The network device may also determine the network service provided for the first business message based on the local policy of the network device, the priority and / or agreement of the network service.

[0300] Optionally, the first service message may include first network service information in addition to carrying the first network service identifier.

[0301] Optionally, the first service message may further include attribute information related to the client, wherein the attribute information related to the client includes any one or more of the following information: state information of the first application, demand information of the first application, the demand information of the first application indicating the quality demand of the first application for the network and / or the demand of the first application for the network function, state information of the first user, demand information of the first user, the demand information of the first user indicating the quality demand of the first user for the network and / or the demand of the first user for the network function, state information of the first service, or demand information of the first service, the demand information of the first service indicating the quality demand of the first service for the network and / or the demand of the first service for the network function. Exemplarily, the state information of the first application includes the working state of the first application and / or the user experience state of the first application, for example, the bandwidth occupancy rate of the first application or the delay value of the first application. Exemplarily, the state information of the first user includes but is not limited to: the delay value of the first user, the packet loss rate of the first user, the bandwidth usage of the first user, the computing resource usage of the first user, whether the operation event of the first user occurs, the number of operations of the first user, the usage time of the first user, or the viewing time of the first user. Exemplarily, the status information of the first service includes, but is not limited to: the delay value of the first service, the packet loss rate of the first service, the bandwidth usage of the first service, or the computing resource usage of the first service, etc. In another example, when the first service is a video service, the status information of the first service includes, but is not limited to: the number of freezes of the video (or live broadcast or on-demand), the delay information of starting playback, the delay information of the first playback, the resolution change of the video (or live broadcast or on-demand), the bit rate change of the video (or live broadcast or on-demand), the picture quality change of the video (or live broadcast or on-demand), or the sound quality change of the video (or live broadcast or on-demand).

[0302] The following describes how the first service message carries the first network service identifier, the first network service information, and / or client-related information. In a possible implementation, the network layer of the first service message carries the above information, and the network layer includes but is not limited to: IPv4, or IPv6. For example, the above information is carried in the IPv6 message header of the first service message.

[0303] In another possible implementation, the transport layer of the first business message carries the above information, and the transport layer includes but is not limited to: user datagram protocol (UDP), transmission control protocol (TCP), quick UDP internet connection (QUIC) protocol, or real-time transport protocol (RTP).

[0304] In yet another possible implementation, the above information is carried in a payload of the first service message.

[0305] In a possible example, for ease of understanding, please refer to Table 2 for the first network service information and application attribute information carried by the first business message.

[0306] Table 2

[0307]

[0308] In another possible example, for ease of understanding, please refer to Table 3 for the first network service information and application attribute information carried by the first business message.

[0309] Table 3

[0310]

[0311]

[0312] In the embodiment of the present application, the network provides a network service identifier for identifying the network service, so that the business message can request the corresponding network service by carrying the network service identifier. The network provides various types of network services to the application by providing an interface between the network service and the network service identifier, which facilitates the application to request network services in a refined manner. The network can provide network services to the application more conveniently to better meet the business needs of the application. The threshold for applications to use network services is lowered, and the degree of integration between applications and the network is improved.

[0313] In combination with the above-mentioned embodiment, the following describes how the first server (application service provider) applies for network services from the second server (network service provider). After the first server applies for network services, it can allocate network services to the client. Take the first server applying for the first network service from the second server as an example. It can be understood that the first server applying for other network services from the second server is similar to applying for the first network service. Figure 4 , Figure 4A business processing method proposed in an embodiment of the present application further includes:

[0314] D1. The first server sends a second request to the second server.

[0315] In step D1, the first server (application service provider) can apply for network services from the second server (network service provider). Specifically, the first server can send a second request to the second server. The first server determines the type of network service that needs to be applied for, such as the need to apply for APN service or network slicing service, and the second request carries the type information of the network service. In addition, the second request may carry the first server's demand information for the network service. Taking the first server applying for the first network service as an example, the second request carries any one or more of the following information: type information of the first network service, or network service demand information.

[0316] The type information of the first network service includes, but is not limited to: application-aware network, network slicing, segment routing strategy, flow detection, deterministic network, virtual private network or quality of service.

[0317] The network service requirement information in step D1 is used to indicate the performance requirement or business requirement of the first server for the applied first network service, such as what performance indicators or business indicators the applied first network service needs to meet. For example, the network service requirement information includes but is not limited to: bandwidth, transmission rate, delay, delay jitter, QoS category, experience quality score, encryption protection level, integrity protection level, packet loss rate, computing resources, application status or network service status, etc.

[0318] In a possible implementation manner, an application server of an application service provider (the application server belongs to the first server) sends a second request to a second server.

[0319] In another possible implementation, a background management platform of an application of an application service provider (the background management platform of the application belongs to the first server) sends a second request to the second server.

[0320] It should be noted that when the first server applies for multiple network services, it can be implemented by carrying type information of multiple network services and / or network service demand information corresponding to multiple network services in one second request; it can also be implemented by sending multiple second requests to the second server, each second request is used to request one or more network services.

[0321] D2. Based on the second request, the second server determines the first network service allocated to the first server.

[0322] In step D2, after receiving the second request, the second server determines the first network service allocated to the first server based on the second request.

[0323] Specifically, the second server determines, according to the type information of the first network service and / or the network service requirement information carried in the second request, a network service that meets the requirement information from a class of network services indicated by the type information.

[0324] For example, the type information of the first network service indicates an SRv6 service. The second server can provide four SRv6 services, namely BSID#1, BSID#2, BSID#3 and BSID#4. According to the network service requirement information in the second request, the second server determines that the SRv6 service corresponding to BSID#2 among the above four SRv6 services meets the requirement indicated by the network service requirement information. Therefore, the second server determines that the SRv6 service corresponding to BSID#2 is the first network service.

[0325] D3. The second server sends a second response to the first server, where the second response carries the first network service information.

[0326] In step D3, after the second server determines the first network service assigned to the first server, in response to the second request, the second server sends a second response to the first server, and the second response carries the first network service information. The first network service information in the second response includes the type information of the first network service and the resource information of the first network service. For the first network service information, please refer to the description of the aforementioned embodiment, which will not be repeated here.

[0327] Optionally, in step D3, the second server may also configure the first network service information to the network device, so that the network device provides the first network service to the service message carrying the first network service identifier according to the first network service information.

[0328] D4. The first server obtains the first network service information according to the second response.

[0329] In the embodiment of the present application, the application service provider (first server) can also apply for network services from the network service provider (second server). After the application service provider obtains network service information of the applied network service from the network service provider, the application service provider obtains the ability to allocate the network service to the client.

[0330] In combination with the above-mentioned embodiment, the following describes a processing method after the first network device receives the first service message. Figure 5 , Figure 5A business processing method proposed in an embodiment of the present application further includes:

[0331] F1. A first network device receives network service configuration information, where the network service configuration information includes network service information corresponding to at least one network service.

[0332] In step F1, the first network device may obtain the network service configuration information in a variety of ways, which are described below respectively.

[0333] In one possible implementation, the first network device may obtain network service configuration information from the second server. For example, after the second server receives the second request sent by the first server, the second server feeds back a second response to the first server. The second server may also send network service configuration information including the first network service information to the first network device, so that the first network device supports the provision of the first network service. For another example, after the network service provider launches a certain network service, the network service provider (second server) sends network service configuration information to the first network device, so that the first network device supports the provision of the network service.

[0334] In another possible implementation, the first network device may obtain the network service configuration information from a network element (or device or platform or software function or server or apparatus) that manages the network device, wherein the network element that manages the network device includes but is not limited to: a network controller, an authentication server, a management plane, an orchestrator, and / or a network management platform for managing the first network device. The network element that manages the network device may obtain the network service configuration information from the second server.

[0335] F2. The first network device receives a first service message, where the first service message carries a first network service identifier and identifier information of a network provider of the first network service.

[0336] After step F1, in step F2, the first network device receives a first service message from the client, the first service message carrying the first network service identifier and the identifier information of the network provider of the first network service. For the first service message, please refer to the aforementioned step S5, which will not be described here.

[0337] F3. The first network device performs authentication verification on the first service message according to the first network service information and network service configuration information carried in the first service message.

[0338] In step F3, after the first network device obtains the first network service information from the first service message, it performs authentication verification on the first service message according to the first network service information and the network service configuration information.

[0339] In a possible implementation, the first network device obtains the identification information of the network service provider of the first network service from the first network service information, and then the first network device determines the identification information of the network service domain from the network service configuration information, and the identification information of the network service domain indicates the network service provider corresponding to the first network device. The first network device matches the identification information of the network service provider of the first network service with the identification information of the network service domain, and if the match is successful, it is considered that the first business message has passed the authentication verification. Exemplarily, the identification information of the network service provider of the first network service is "operator A", and the identification information of the network service domain in the first network device includes "operator A" and "operator B". Since the identification information of the network service domain in the first network device includes the identification information of the network service provider of the first network service, the first network device considers that the first business message has passed the authentication verification.

[0340] In another possible implementation, the network service configuration information also includes authentication information. The first network device obtains authentication information from the first network service information of the first service message. Then the first network device matches the authentication information in the network service configuration information with the authentication information in the first network service information. If the match is successful, it is considered that the first service message passes the authentication verification. Exemplarily, the authentication information of the first network service information is "HMAC#1", and the authentication information of the network service configuration information in the first network device is "HMAC#1". Since the authentication information of the first network service information is the same as the authentication information of the network service configuration information, the first network device considers that the first service message passes the authentication verification. In another example, the authentication information of the first network service information is "HMAC". The first network device determines that an authentication algorithm (for example, an HMAC algorithm) needs to be executed on the first service message based on the authentication information and the network service configuration information. If the first service message passes the authentication verification of the authentication algorithm, the first network device determines that the first service message passes the authentication verification; if the first service message fails to pass the authentication verification of the authentication algorithm, the first network device determines that the first service message fails to pass the authentication verification.

[0341] It should be noted that the first network device can perform authentication verification only based on the identification information of the network provider of the first network service in the first network service information, or can perform authentication verification only based on the authentication information in the first network service information, or can perform authentication verification based on both the identification information of the network provider of the first network service in the first network service information and the authentication information in the first network service information. The embodiments of the present application are not limited to this.

[0342] If the first service message passes the authentication check, the process proceeds to step F4; if the first service message fails the authentication check, the first network device forwards the first service message according to the normal routing forwarding process of the first service message, for example, forwarding the first service message according to the routing information of the first service message. Alternatively, the first network device performs packet loss processing on the first service message.

[0343] Optionally, there may be multiple implementation methods for the authentication and verification processing of the first service message.

[0344] In a possible implementation, the first network device may perform the authentication verification process. For example, after the client sends the first service message, the first network device that receives the first service message performs the authentication verification process.

[0345] In another possible implementation, it can also be performed by a network node responsible for authentication verification. For example, after the client sends the first business message, the network device that receives the first business message forwards the first business message to the network node according to the authentication service node information carried in the first business message, and the network node performs authentication verification processing. The authentication service node information indicates the network node that provides authentication service for the message requesting the first network service.

[0346] The network node may be a server with an authentication verification function, a network device with an authentication verification function, or a service chain or service function with an authentication verification function, and the embodiments of the present application are not limited to this. For example, the network node with an authentication verification function may be a network service boundary node in the direction of the inbound port connected to the client. For another example, the network node with an authentication verification function may be a network service boundary node in the direction of the outbound port, where the outbound port direction refers to another direction opposite to the inbound port direction.

[0347] It should be noted that the network service boundary node in the direction of the inbound port can support the provision of the first network service to the first business message, that is, the network service boundary node is jointly set up with the first network device; the network service boundary node in the direction of the inbound port may also not support the provision of the first network service to the first business message. When the network service boundary node in the direction of the inbound port performs authentication and verification processing on the first business message and determines that the first business message passes the authentication and verification processing, the network service boundary node in the direction of the inbound port forwards the first business message to the first network device, and the first network device provides the first network service to the first business message.

[0348] F4. Based on the network service provider of the first network service corresponding to the first network device, the first network device provides the first network service for the first business message.

[0349] In step F4, based on the network service provider of the first network service corresponding to the first network device, the first network device provides the first network service for the first business message. For example, if the first network service is a network slicing service, the first network device transmits the first business message in the network slice corresponding to the network slicing service. For another example, if the first network service is a network measurement service, the first network device performs network measurement on the first business message according to the first network service. For another example, if the first network service is an APN service, the first network device provides the APN service for the first business message according to the first network service. For another example, if the first network service is an SRv6 Policy, the first network device forwards the first business message along the path of the SRv6 Policy according to the first network service.

[0350] In one possible implementation, if the first business message carries a single network service information, the network service information includes identification information of a network service provider. Then, when the first business message is forwarded between network devices, it can pass through network devices in a network service domain, and the network devices in the network service domain provide network services to the first business message. Network devices in the same network service domain have the same identification information of the network service domain. When the identification information of the network service domain matches the identification information of the network service provider of the first business message, the network devices in the network service domain provide network services to the business message. When the first business message is forwarded between network devices, it can also pass through network devices in multiple network service domains, and network services can be provided by network devices in a specific network service domain that matches the identification information of the network service provider of the first business message.

[0351] In another possible implementation, if the first business message carries multiple network service information, the multiple network service information may include identification information of the same network service provider, that is, the network services corresponding to the multiple network service identifications carried by the first business message belong to the same network service provider; the multiple network service information may also correspond to the identification information of multiple network service providers respectively, that is, the network services corresponding to the multiple network service identifications carried by the first business message belong to different network service providers. The following is an introduction respectively: multiple network service information includes identification information of the same network service provider, and the network equipment of the specific network service domain that matches the identification information of the network service provider provides one or more network services corresponding to the multiple network service information. Multiple network service information includes identification information of multiple network service providers, the first business message is forwarded between network equipment of multiple network service domains, and the network equipment of the specific network service domain that matches the identification information of the network service provider provides one or more network services corresponding to the multiple network service information.

[0352] Exemplarily, the identification information (provider ID) of the network service provider in the first business message includes: "underlay" and "overlay". The first business message is first forwarded to the network device of network service domain #1, and the identification information of the network service domain of the network device in network service domain #1 is "underlay". The network device in network service domain #1 provides the first business message with "underlay" related network services, and the specific network services provided are indicated by the network service identifier carried by the first business message. Then, the first business message is forwarded to the network device of network service domain #2, and the identification information of the network service domain of the network device in network service domain #2 is "overlay". The network device in network service domain #2 provides the first business message with "overlay" related network services. It can be understood that the first business message can also be forwarded to the network device of network service domain #2 first, and the network device of network service domain #2 provides network services before forwarding it to the network device of network service domain #1, and then the network device of network service domain #1 provides network services. The embodiment of the present application does not limit this.

[0353] Optionally, when the first network device acts as the head node of the network service domain, the first network device can also add the first network service information carried in the first business message to the first business message again, so that other first network devices that provide the first network service to the first business message can easily obtain the first network service information and improve the quality of network service. Specifically, after the first network device (the head node in the network service domain) receives the first business message, it obtains the first network service information and / or client-related attribute information from the first business message. Then, the first network device adds the first network service information and / or client-related attribute information to the first business message again to obtain the added first business message. The first network device forwards the added first business message to the next hop node.

[0354] In one possible implementation, the first network device adds a first message header to the first business message according to the first network service. Then, the first network device adds the first network service information and / or the attribute information related to the client to the first message header, and obtains the added first business message. The first message header is a message header of the network layer of the first business message, or the first message header is a message header of the transport layer of the first business message. For example, when the first network service is an SRv6 service, the first network device encapsulates a segment routing extension header (Segment Routing Header, SRH) for the first business message. The first network device adds the first network service information and / or the attribute information related to the client to the SRH, and obtains the added first business message.

[0355] In another possible implementation, the first network device adds the first network service information and / or client-related attribute information carried by the first service message to the payload of the first service message to obtain the added first service message, so as to facilitate the first service message to traverse the network service domain that does not support certain message headers and causes message loss.

[0356] In another possible implementation, after the client sends the first business message, the network service boundary node of the inbound port may perform authentication verification on the first business message. If the authentication verification passes, the network service boundary node of the inbound port adds the first network service information carried in the first business message to the first business message again to obtain the added first business message. Then the network service boundary node of the inbound port forwards the added first business message to the next-hop node. If the next-hop node is the first network device, the first network device provides the first network service to the first business message based on the added first business message. The specific adding method is the same as the aforementioned adding method of the first network device, which will not be repeated here.

[0357] Optionally, when the first network device serves as the tail node at the end of the network service domain, after receiving the added first service message, the first network device strips the first network service information and / or client-related attribute information added again from the added first service message to obtain the first service message. Then, the first network device forwards the first service message.

[0358] In another possible implementation, after the tail node (first network device) of the network service domain forwards the added first service message, the network service border node of the egress port receives the added first service message. Then, the network service border node of the egress port strips the first network service information and / or client-related attribute information added again from the added first service message to obtain the first service message. The network service border node of the egress port forwards the first service message to the next hop node.

[0359] The network service border node may be other network devices outside the network service domain, and the network service border node does not support providing the first network service. The network service border node may be the first network device in the network service domain, for example, the network service border node of the ingress port is co-located with the head node (first network device) of the network service domain, and the network service border node of the egress port is co-located with the tail node (first network device) of the network service domain.

[0360] In an embodiment of the present application, the first network device provides the first network service for the first business message according to the first network service identifier carried by the first business message. The network provides multiple types of network services to the application by providing an interface between the network service and the network service identifier, so that the application can request the network service in a refined manner. The network can provide network services to the application more conveniently to better meet the business needs of the application. The threshold for applications to use network services is lowered, and the degree of integration between applications and the network is improved.

[0361] In combination with the above-mentioned embodiment, the forwarding and processing flow of the first service message in the network service domain is introduced next.

[0362] In combination with the above embodiment, in a possible implementation manner, a network service domain including a head node, an intermediate node and an end node is used as an example for description, and the head node, the intermediate node and the end node all belong to the first network device. Figure 6 , Figure 6 This is a schematic diagram of an application scenario in an embodiment of the present application, and the application scenario includes:

[0363] G1. The head node receives a first service message. Specifically, the head node receives the first service message from the client.

[0365] G3. The head node obtains the first network service information.

[0366] G4. The head node adds the first network service information to the first service message again.

Specifically, after the tail node receives the first business message that is added, it determines the first network service and provides the first network service for the first business message according to the first network service identifier carried by the first business message that is added. Then, the tail node executes the forwarding process of the first business message. In the forwarding process, the tail node strips the first network service information that is added again from the first business message to obtain the first business message.

If the authentication verification passes, proceed to step H3; if the authentication verification fails, perform normal routing forwarding on the first service message.

[0376] It should be noted that step H2 is an optional step. When step H2 is executed, step H12 may not be executed; or, when step H12 is executed, step H2 may not be executed; or, both step H2 and step H12 may be executed, which is not limited in the embodiment of the present application.
