[0067] To make the technical problems solved by the present disclosure, technical solutions and advantages clearer, the following will be described in detail with reference to the drawings and specific embodiments.

[0068] It should be understood that the terms "one embodiment" or "an embodiment" as used throughout this specification mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. Therefore, the appearance of the phrase "in one embodiment" or "in an embodiment" in various places throughout the specification is not necessarily referring to the same embodiment. In addition, these particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0069] In various embodiments of the present disclosure, it should be understood that the size of the serial number of the following processes does not mean the order of execution, and the execution order of the processes should be determined according to their functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present disclosure.

[0070] The terms "first", "second", and the like in the present disclosure are used to distinguish similar objects, and are not used to describe a particular order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second" are usually a category, not limited to the number of objects, for example, the first object can be one or more. In addition, "or" in the present disclosure means at least one of the connected objects. For example, "A or B" covers three scenarios, namely, scenario one: including A and not including B; scenario two: including B and not including A; scenario three: including A and B. The character " / " generally represents that the objects before and after are in an "or" relationship.

[0071] In addition, the terms "system" and "network" are often used interchangeably in this document.

[0072] In the embodiments provided in the present disclosure, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that the determination of B according to A does not mean that B is determined only according to A, but B can also be determined according to A and / or other information.

[0073] As shown in FIG. 1, the embodiments of the present disclosure provide a processing method of a network service, applied to a first node, the first node comprising at least one of a network storage function (NRF) and a service communication proxy (SCP), the method comprising:

[0074] Step 101: receiving a first service discovery request, the first service discovery request comprising information of at least two first services.

[0075] Optionally, the step specifically comprises that the first node receives the first service discovery request sent by a third node, the third node being an application function (AF), a user equipment (UE), a core network (CN) network function or a radio access network (RAN) network function.

[0076] Optionally, the at least two first services can come from the same network function, or come from different network functions, or come from different independent services.

[0077] The independent service mentioned above refers to a service independent of a network function, that is, there is no binding relationship between the service and the network function. In the case that the at least two first services come from the same network function or come from different network functions, the existing technology can be compatible, that is, the service can depend on the network function, and in the case that the at least two first services come from different independent services, the service can exist independently.

[0078] Step 102: sending a first service discovery request response, the first service discovery request response comprising registration information of a second node, the second node being a network function or a network unit capable of providing the at least two first services.

[0079] For example, the registration information of the second node comprises an identifier of the second node, a function of the second node, an interface protocol type supported by the second node, and / or a protocol version, etc.

[0080] The second node mentioned above is a network function or a network unit, and the at least two first services can be provided through the second node, thereby achieving the purpose of on-demand combination of services.

[0081] Optionally, the network element comprises a set of network functions of different types, which can be used to adapt to specific scenarios.

[0082] Optionally, the first service supports at least two interface protocol types.

[0083] Optionally, the first service supports a first interface protocol type and a second interface protocol type, the first interface protocol type is a standard defined service interface protocol, which is used for interconnection of devices from different manufacturers or is used to ensure backward compatibility with a 5G network, and the second interface protocol type is a high-performance interface protocol, which can be specific to a manufacturer and is mainly used for internal communication of an NF or a network element.

[0084] In the embodiments of the present disclosure, a first service discovery request is received, the first service discovery request comprising information of at least two first services; a first service discovery request response is sent, the first service discovery request response comprising registration information of a second node, the second node being a network function or a network element capable of providing the at least two first services. In the above scheme, the at least two first services are integrated into one network function or network element through a service discovery process, that is, the at least two first services are integrated into the second node, thereby achieving the purpose of on-demand combination of services.

[0085] Optionally, after receiving the first service discovery request, the method further comprises:

[0086] According to the first service discovery request, a second node is defined, and registration information of the second node is obtained.

[0087] In the embodiments of the present disclosure, defining the second node comprises defining a name, an ID, a function, a supported interface protocol type, and / or a protocol version of the node.

[0088] As an implementation manner, in a case where the first node is an NRF, the obtaining of the registration information of the second node comprises:

[0089] A creation request of the second node is sent to an SCP;

[0090] A creation response sent by the SCP or registration information sent by the second node is obtained, the creation response comprising the registration information of the second node.

[0091] For example, as shown in FIG. 2, the processing method of the network service in the embodiments of the present disclosure comprises:

[0092] Step 1: A third node sends a first service discovery request;

[0093] Step 2: An NRF defines a second node.

[0094] Step 3: The NRF sends a create request of the second node to the SCP.

[0095] Step 4: The SCP creates the second node.

[0096] Step 5a: The SCP sends a create response to the NRF, the create response including registration information of the second node.

[0097] Step 5b: The second node sends the registration information of the second node.

[0098] The step 5b and the step 5a are parallel steps.

[0099] Step 6: The NRF sends a first service discovery request response to the third node.

[0100] As another implementation manner, the first node is an SCP having the function of the NRF, and the obtaining the registration information of the second node includes:

[0101] creating the second node and obtaining the registration information of the second node.

[0102] For example, as shown in FIG. 3, the processing method of the network service of the embodiment of the disclosure includes:

[0103] Step 1: The third node sends a first service discovery request.

[0104] Step 2: The SCP defines the second node.

[0105] Step 3: The SCP creates the second node.

[0106] Step 4: The SCP sends a first service discovery request response to the third node, the first service discovery request response including the registration information of the second node.

[0107] Optionally, the first service discovery request further includes at least one of:

[0108] a first indication, the first indication being used to indicate that the at least two first services are integrated into one network function or network element;

[0109] requirements of the at least two first services, for example, location information of the at least two first services.

[0110] In the embodiment of the disclosure, the first node can integrate the at least two first services into one network element or network function based on the above first indication. In the case that the above first service discovery request includes the requirements of the at least two first services, the first node can define and create the second node meeting the requirements based on the requirements of the first service.

[0111] Optionally, the method of the embodiments of the present disclosure further comprises:

[0112] obtaining registration information corresponding to the service, the registration information comprising an interface protocol type supported by the service and / or a protocol version associated with the interface protocol type, and the service supporting at least two interface protocol types.

[0113] The second node is determined based on the registration information corresponding to the service.

[0114] As shown in the flowcharts of FIGS. 2 and 3, the scheme of the embodiments of the present disclosure can also perform service-level registration. Traditional service registration is network function-level registration. The embodiments of the present disclosure can support both service-level registration, i.e., independent service registration, and network function registration. In this way, based on service-level registration, subsequent on-demand combination of multiple services can be facilitated, for example, multiple services are integrated into a network function or network element.

[0115] In related technologies, it is defined that NFs and NFs, and NFs and service agents interact through a South Bound Interface (SBI) interface, and the SBI interface protocol is unique, i.e., based on REST-HTTP / 2. However, how NF services interact is not defined in the standard. Since the SBI interface protocol is unique, the end-to-end latency performance under the service-oriented architecture is significantly reduced, especially in the indirect communication mode (i.e., NFs interact through SCP), kernel processing, etc. increase the processing delay. In the embodiments of the present disclosure, each network function or each network function service supports at least two types of interface protocols, such as Hypertext Transfer Protocol (HTTP) / 2 over Quick UDP Internet Connections (QUIC), HTTP / 3 over QUIC, gRPC over HTTP / 2, gRPC over HTTP / 3, RDMA over HTTP / 2, etc. One of them is a standard-defined service-oriented interface protocol, which is used for interconnection of devices from different manufacturers or to ensure backward compatibility with 5G networks; at least one other is a high-performance interface protocol, which can be manufacturer-specific, and is mainly used for internal communication of NFs or elements.

[0116] The gRPC (google Remote Procedure Call Protocol) protocol is a high-performance, general-purpose RPC open source software framework based on the HTTP2 protocol released by Google;

[0117] The above-mentioned QUIC (Quick UDP Internet Connections) protocol is a brand-new web development protocol based on the User Datagram Protocol (UDP).

[0118] Optionally, the method of the embodiments of the present disclosure further comprises:

[0119] obtaining a second service discovery request, the second service discovery request being used to request to discover a service provider providing a second service;

[0120] determining, according to the second service discovery request and registration information corresponding to the service, an interface protocol type used by the second service and a network service provider;

[0121] sending a second service discovery request response, the second service discovery request response comprising the interface protocol type used by the second service and the network service provider.

[0122] In the embodiments of the present disclosure, when a service is registered, an NF or a service informs an NRF or an SCP of an interface protocol type and / or a protocol version supported by the NF or the service.

[0123] For example, as shown in FIG. 4, the flow comprises:

[0124] Step 1: A consumer sends a second service discovery request to an SCP.

[0125] Optionally, the consumer can be the third node described above.

[0126] Step 2: The SCP determines an interface protocol used and a service provider (Producer).

[0127] Step 3: The SCP forwards the second service discovery request to the corresponding Producer.

[0128] Step 4: The SCP obtains a second service discovery request response sent by the Producer.

[0129] Step 5: The SCP sends the second service discovery request response to the consumer.

[0130] The inter-service communication mode in the embodiments of the present disclosure comprises the following four communication modes:

[0131] Mode A: direct communication mode without service discovery;

[0132] Mode B: direct communication mode with service discovery;

[0133] Mode C: indirect communication mode without proxy discovery;

[0134] Mode D: Proxy discovery indirect communication mode.

[0135] Overall, direct communication is adopted between services, including Mode A and Mode B. In these two modes, service consumers perform service selection based on local configuration or service producer information (NF profile) obtained from the NRF. The NF profile includes NF type, fully qualified domain name (FQDN) or Internet Protocol (IP) address of the NF, name of supported services, and the like.

[0136] In the related art, indirect communication based on service communication proxies is introduced between services, including Mode C and Mode D. Thus, each NF only needs to focus on its own business processing logic, and hands over its original service discovery, routing forwarding and other functions to the SCP to complete, making the NF function more lightweight. In these two modes, the SCP acts as a proxy function of the service consumer, and performs selection of the service producer based on the NRF or operator policy. The service producer in the embodiments of the present disclosure can also be described as a service provider.

[0137] Among them, the communication model of Mode A is shown in FIG. 5, the communication model of Mode B is shown in FIG. 6, the communication model of Mode C is shown in FIG. 7, and the communication model of Mode D is shown in FIG. 8.

[0138] In order to support the scheme of the embodiments of the present disclosure (each NF or NF service supports at least two types of interface protocols), the existing communication model needs to be enhanced as follows:

[0139] (1) Mode (Model) A: Each NF or NF service stores all the interface protocols supported by the NF or NF service, and indicates the specific interface protocol used in the service request.

[0140] (2) Model B: Each NF or NF service registers the supported interface protocol to the NRF, and selects the producer supporting the required interface protocol through service discovery.

[0141] (3) Model C: Each NF or NF service registers the supported interface protocol to the NRF, and selects the producer supporting the required interface protocol through interaction with the NRF, and the SCP completes message forwarding.

[0142] (4) Model D: Each NF or NF service registers supported interface protocol cases to the NRF, and the SCP selects a producer supporting the required interface protocol after receiving a service request of the consumer, interacting with the NRF.

[0143] On this basis, three new communication models can be added to achieve more efficient communication:

[0144] (5) Model E: Similar to the enhanced Model C, the difference is that there is no service discovery process, and a routing decision interaction process is added; specifically, the SCP generates a routing decision and directly sends it to the consumer through the xDS interface (non-standardized SBI), and the consumer selects the producer based on the routing decision.

[0145] (6) Model F: Similar to the enhanced Model D, the difference is that there is no service discovery process, and a routing decision interaction process is added; specifically, the SCP generates a routing decision and directly sends it to the consumer through the xDS interface (non-standardized SBI), and the consumer selects the producer based on the routing decision. Compared with Model E, Model F also does not have a standardized service registration process.

[0146] The above-mentioned Model E and Model F avoid the latency caused by the need for OS kernel processing when forwarding through the sidecar proxy in the traditional indirect communication mode (i.e., Model C / D), thereby improving communication efficiency.

[0147] (7) Model G: Further enhanced based on Model E, the difference is that there is no routing decision interaction process. The consumer sends a message directly to the SCP, which determines the producer and completes message forwarding.

[0148] In the above-mentioned Model G, the SCP naturally carries the capabilities of the NRF, avoiding the latency caused by interface interaction between the SCP and the NRF, making the service discovery and selection process simpler.

[0149] Among them, the communication model of Model E is shown in FIG. 9, the communication model of Model F is shown in FIG. 10, and the communication model of Model G is shown in FIG. 11.

[0150] In the above-mentioned flow shown in FIG. 4, for Model D, the service is registered to the NRF, and the SCP can obtain relevant information by interacting with the NRF; for Model G, the service is registered to the SCP (with built-in NRF or similar registration function), and the SCP can directly obtain relevant information.

[0151] Optionally, the consumer can also determine the interface protocol to be used. For mode B, mode C, mode E and mode F, the NF or service needs to inform the NRF or SCP of the supported interface protocol type and / or protocol version at service registration, where the protocol version can be used to infer the supported interface protocol type.

[0152] Based on this, the method of the embodiments of the present disclosure further includes:

[0153] Method 1: obtaining a third service discovery request, the third service discovery request including a first interface protocol type and / or a first protocol version of a third service; sending a third service discovery request response, the third service discovery request response including at least one service provider capable of providing the third service and supporting the first interface protocol type, the first interface protocol type being an interface protocol type expected by the consumer, and the first protocol version being a protocol version associated with the first interface protocol type.

[0154] In this method 1, the consumer sends the expected interface protocol type and / or protocol version to the NRF through the service discovery request to obtain the producer information supporting the interface protocol type when discovering the service.

[0155] Alternatively, method 2: obtaining a fourth service discovery request, the fourth service discovery request being used to request to discover a service provider providing a fourth service; sending a fourth service discovery response, the fourth service discovery response including all service providers capable of providing the fourth service and the interface protocol type supported by each of the service providers.

[0156] In this method 2, the consumer obtains the service provider information (producer profile) meeting the communication requirement through the service discovery request response, the profile carrying the interface protocol type and / or protocol version supported by the producer, and the producer and the interface protocol type to be used are determined based on the producer profile.

[0157] Alternatively, method 3: sending routing policy information, the routing policy information being related to the interface protocol type and / or protocol version, and the routing policy information being used by the consumer to determine the interface protocol type and / or protocol version of the service.

[0158] The routing policy information in the embodiments of the present disclosure can also be described as routing decision information.

[0159] In the method 3, the consumer receives the routing policy related to the interface protocol type and / or protocol version sent by the SCP, and determines the interface protocol type and the producer to be used based on the routing policy. This way is mainly used for the Model E or Model F.

[0160] As shown in FIG. 12, the flow of the embodiment of the present disclosure includes:

[0161] Step 1: At the time of service registration, the NF or service needs to inform the NRF or SCP of the supported interface protocol type and / or protocol version.

[0162] Step 2: The consumer determines the interface protocol type and the producer.

[0163] In this embodiment, the consumer can determine the interface protocol type and the producer in the following three implementation manners.

[0164] Implementation manner 1: The consumer determines the interface protocol type and the producer to be used based on the local strategy. This way is mainly used for Model A.

[0165] Implementation manner 2: The interface protocol type and the producer to be used are determined based on service discovery. This way is mainly used for Model B / C. Specifically, the implementation manner includes the following two ways.

[0166] Way 2-1: The consumer sends the expected interface protocol type and / or protocol version to the NRF through the service discovery request to obtain the producer information supporting the interface protocol type at the time of service discovery.

[0167] Implementation manner 2-2: The consumer obtains the service provider information (producer profile) meeting the communication requirement through the service discovery request response. The profile carries the interface protocol type and / or protocol version supported by the producer, and the producer and the interface protocol type to be used are determined based on the producer profile.

[0168] Implementation manner 3: The determination is based on the routing policy. Specifically, the consumer receives the routing policy related to the interface protocol type and / or protocol version sent by the SCP, and determines the interface protocol type and the producer to be used based on the routing policy. This way is mainly used for the Model E or Model F.

[0169] Step 3: The consumer sends the service request message to the corresponding producer / SCP.

[0170] Wherein, for the direct communication mode (i.e. mode A or B), the service request message is sent to the producer, and for the indirect communication mode (i.e. mode C, E or F), the service request message is sent to the SCP.
