Radio Network Node Service Indication Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks lack an efficient mechanism for service selection, relying on network selection mechanisms that do not support a service-centric view, making it difficult for user equipment (UE) to access desired services without prior credentials or subscriptions.
Innovation Solution
The proposed solution involves a method where a radio network node receives a service indication from a UE, selects a network node that supports the indicated service, and transmits a service request to the selected network node, allowing the UE to access the desired service without prior network registration or specific credentials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network selection mechanisms are used for service access, then existing network infrastructure can be utilized, but service selection efficiency deteriorates and UE cannot access services without prior credentials
Solution Approach 1:
The patent segments the service access process into two independent phases: service selection (UE side) and service provisioning (network side). The UE selects services based on service indications from the network without needing prior credentials, while the network node handles credential verification separately. This segmentation resolves the contradiction by enabling efficient service selection independent of credential verification.
Solution Approach 2:
The patent introduces service indications as an intermediary mechanism between the network and UE. These indications convey service availability information from the network to the UE, enabling the UE to make informed service selections without direct network registration or credential verification. This intermediary layer decouples service selection from credential requirements.
2Loss of information
If service indications are broadcast by the network, then service information becomes available to UEs, but network broadcasting burden increases
Solution Approach 1:
The patent applies local quality by broadcasting service indications only in specific system information blocks (SIBs) rather than all network broadcasts. The network node selectively includes service indication information in relevant SIBs, providing service information where needed without overwhelming the broadcasting system. This targeted approach reduces overall network broadcasting burden while maintaining service information availability.
3Ease of operation
If UEs perform service selection without prior credentials, then service access flexibility improves, but network security verification complexity increases
Solution Approach 1:
The patent implements preliminary action by having the network node prepare and broadcast service indications in advance, containing service availability and selection criteria. This allows UEs to perform simple service selection based on pre-provided information, while the network node handles the more complex credential verification and service provisioning processes separately, maintaining security without complicating UE operation.

AI summary
A method performed by a radio network node for handling services in a wireless communications network. The radio network node receives, from a user equipment (UE), an indication indicating selection of a service associated with a service indication out of at least one service indication; and based on the received indication, selects a network node that supports the service indicated by the indication.
