Abstract

Disclosed in the embodiments of the present application are a resource query method and apparatus, a device, and a storage medium. Said method comprises: a service user NF initiating a service access request to a service provider NF, the service access request carrying query conditions for a resource, the query conditions being used for indicating a combined query relationship of at least two query parameters; and the service user NF receiving a service access response returned by the service provider NF.

First claim

The invention claimed is:

1. A resource query method, applicable to a service consumer Network Function (NF) in fifth Generation of Cellular technology networks (5G), comprising:
initiating, by the service consumer NF, a request for accessing service to a service provider NF, wherein the request for accessing service is used to request the service provider NF to access a resource, the resource comprising at least one of 5G subscription data or 5G policy data, wherein the request for accessing service carries query conditions of the resource, the query conditions are used to indicate a combined query relationship of at least two query parameters, and the at least two query parameters are used to filter the resource; and
receiving, by the service consumer NF, a response for accessing service, the response for accessing service being returned by the service provider NF according to the query conditions and the response for accessing service being a Hyper Text Transfer Protocol (HTTP) response,
wherein the combined query relationship comprises a conditional expression formed by combining the at least two query parameters,
wherein the combined query relationship comprises a conditional expression formed by nesting at least two conditional expressions, and the at least two conditional expressions are concatenated by logical operations,
wherein the method further comprises:
in response to a query parameter that meets a same preset condition repeatedly appearing multiple times in a conditional expression, simplifying the conditional expression in a dictionary manner, and taking the query parameter appearing repeatedly that meets the same preset condition as an entry in a dictionary.

2. The method of claim 1 , wherein the request for accessing service is a request including a resource query requirement, and types of the request for accessing service comprise at least a resource acquisition request and a resource deletion request.

3. The method of claim 1 , wherein the method comprises at least one of the following:
the query conditions of the resource are expressed in a JavaScript Object Notation (JSON) format; or
when HTTP is adopted, the query conditions of the resource are located in a request line of the request for accessing service.

4. The method of claim 1 , wherein the conditional expression formed by combining the at least two query parameters is used to indicate a logical relationship among multiple query parameters, and the logical relationship comprises at least AND and OR.

5. The method of claim 1 , wherein the combined query relationship comprises a priority of each query parameter for meeting a preset condition; and
wherein a different priority or a same priority is defined for the preset condition met by each query parameter, and the preset condition comprises EQUAL TO or NOT; or the combined query relationship comprises priorities of different combinations of query parameters, and different priorities are defined for the different combinations of query parameters.

6. The method of claim 1 , wherein the nested at least two conditional expressions have different priorities or a same priority.

7. A resource query method, applicable to a service provider Network Function (NF) in fifth Generation of Cellular technology networks (5G), comprising:
receiving, by the service provider NF, a request for accessing service initiated by a service consumer NF, wherein the request for accessing service is used to request the service provider NF to access a resource, the resource comprising at least one of 5G subscription data or 5G policy data, wherein the request for accessing service carries query conditions of the resource, the query conditions are used to indicate a combined query relationship of at least two query parameters, and the at least two query parameters are used to filter the resource; and
returning, by the service provider NF, a response for accessing service to the service consumer NF according to the query conditions and types of the request for accessing service, the response for accessing service being a Hyper Text Transfer Protocol (HTTP) response,
wherein the combined query relationship comprises a conditional expression formed by combining the at least two query parameters,
wherein the combined query relationship comprises a conditional expression formed by nesting at least two conditional expressions, and the at least two conditional expressions are concatenated by logical operations,
wherein the method further comprises:
in response to a query parameter that meets a same preset condition repeatedly appearing multiple times in a conditional expression, simplifying the conditional expression in a dictionary manner, and taking the query parameter appearing repeatedly that meets the same preset condition as an entry in a dictionary.

8. The method of claim 7 , wherein returning, by the service provider NF, the response for accessing service to the service consumer NF according to the query conditions and the types of the request for accessing service comprises:
performing, by the service provider NF, resource query according to the combined query relationship of the at least two query parameters; and
returning, by the service provider NF, the response for accessing service to the service consumer NF according to a resource query result and the types of the request for accessing service.

9. A service consumer Network Function (NF) in fifth Generation of Cellular technology networks (5G), comprising:
a memory; and
a processor,
wherein the memory stores computer programs that are configured to be executed on the processor, and when the computer programs are executed by the processor, the processor is configured to:
initiate a request for accessing service to a service provider NF, wherein the request for accessing service is used to request the service provider NF to access a resource, the resource comprising at least one of 5G subscription data or 5G policy data, wherein the request for accessing service carries query conditions of the resource, the query conditions are used to indicate a combined query relationship of at least two query parameters, and the at least two query parameters are used to filter the resource; and
receive a response for accessing service, the response for accessing service being returned by the service provider NF according to the query conditions and the response for accessing service being a Hyper Text Transfer Protocol (HTTP) response,
wherein the combined query relationship comprises a conditional expression formed by combining the at least two query parameters,
wherein the combined query relationship comprises a conditional expression formed by nesting at least two conditional expressions, and the at least two conditional expressions are concatenated by logical operations,

wherein the processor is further configured to:
in response to a query parameter that meets a same preset condition repeatedly appearing multiple times in a conditional expression, simplify the conditional expression in a dictionary manner, and take the query parameter appearing repeatedly that meets the same preset condition as an entry in a dictionary.

10. The service consumer NF of claim 9 , wherein the request for accessing service is an access request including a resource query requirement, and types of the request for accessing service comprise at least a resource acquisition request and a resource deletion request.

11. The service consumer NF of claim 9 , wherein the query conditions of the resource comprise at least one of the following:
the query conditions of the resource that are expressed in a JavaScript Object Notation (JSON) format; or
when HTT
