5G Service Invocation Flow with Embedded Downstream Call Results
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The service atomization design of the 5G core network complicates the service processing procedure by increasing the number of service process steps and interactions.
Innovation Solution
The provider of a first service includes service invocation information or result for associated second services in its response to the service consumer, optimizing the service processing logic and reducing complexity by omitting unnecessary service discovery and invocation logic.

Engineering Contradiction Analysis
1Adaptability or versatility
If service atomization design is adopted in 5G core network, then service independence and reusability are improved, but service processing procedure complexity increases
Solution Approach 1:
The patent applies preliminary action by having the service provider perform service invocation in advance and include the invocation result in the service response. Specifically, the service provider invokes the second service before the service consumer requests it, and returns the invocation result (such as subscription data change notification) along with the first service response. This eliminates the need for the service consumer to perform additional service discovery and invocation operations, thereby reducing service processing procedure complexity while maintaining service independence and reusability.
2Reliability
If service discovery and invocation operations are performed separately, then service processing completeness is ensured, but service processing steps increase
Solution Approach 1:
The patent applies merging by combining multiple service operations into a single integrated process. The service provider performs both the first service processing and the second service invocation, then merges these operations by including the second service invocation result directly in the first service response. This allows the service consumer to obtain all necessary information in one interaction, ensuring service processing completeness while reducing the number of service processing steps from multiple separate operations to a single consolidated operation.

AI summary
A service invocation method and a network device are provided. The method applied to a service provider side includes: receiving a service request for a first service by a provider of the first service, the service request being sent by a service consumer; sending a service response for the first service by the provider of the first service to the service consumer, wherein the service response for the first service includes service invocation information or a service invocation result of at least one second service associated with the first service, the service invocation information is configured to instruct the service consumer to invoke the second service.
