QoS Initiation Preference Indicator for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, there is a lack of clarity on whether network-initiated or device-initiated Quality of Service (QoS) should be responsible for establishing QoS for applications that support both options, leading to inefficient resource allocation and erroneous service charges.
Innovation Solution
A method and apparatus that unambiguously indicate a preference for network-initiated or device-initiated QoS by transmitting an indicator to mobile devices, allowing the core network to establish QoS when preferred, and enabling mobile devices to release unnecessary resources by comparing packet filters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both network-initiated QoS and device-initiated QoS are supported for applications, then service flexibility and adaptability are improved, but resource allocation efficiency deteriorates due to duplicative resource allocation
Solution Approach 1:
The patent inverts the traditional approach by having the network indicate its preference for QoS initiation to the device. Instead of the device independently deciding whether to initiate QoS, the network's preference indicator guides the device's behavior, thereby eliminating duplicative resource allocation while maintaining service flexibility.
Solution Approach 2:
The network provides feedback to the device through a preference indicator that specifies whether the network or device should initiate QoS. This feedback mechanism enables the device to align its QoS initiation behavior with network preferences, preventing resource duplication while preserving adaptability.
2Adaptability or versatility
If both network-initiated QoS and device-initiated QoS are supported for applications, then service adaptability is improved, but service charging accuracy deteriorates due to erroneous service charges
Solution Approach 1:
The patent resolves the charging accuracy issue by inverting the decision-making process: instead of the device independently determining QoS initiation, the network's preference indicator explicitly directs whether network or device should initiate QoS. This eliminates ambiguity in charging responsibility and ensures accurate service billing.
Solution Approach 2:
The network provides feedback through the preference indicator that clearly specifies which entity (network or device) is responsible for QoS initiation. This feedback mechanism eliminates charging errors by ensuring that only the indicated entity initiates QoS and incurs associated charges.
3Reliability
If the core network establishes QoS for all applications, then network control and QoS reliability are improved, but device autonomy and operational flexibility deteriorate
Solution Approach 1:
The patent introduces dynamics by making the QoS initiation approach adaptable based on network preferences rather than being statically fixed. The network can dynamically indicate its preference for each application or service type, allowing devices to operate autonomously when appropriate while maintaining network control when needed, thus balancing reliability and device autonomy.
4Ease of operation
If mobile devices independently initiate QoS for all applications, then device autonomy is improved, but network control and resource management efficiency deteriorate
Solution Approach 1:
The patent enables dynamic QoS initiation behavior where devices can operate autonomously when the network indicates device-initiated QoS is preferred, while switching to network-controlled initiation when efficiency requires it. This dynamic approach maintains device autonomy where appropriate while improving overall network resource management efficiency.

AI summary
Systems and methodologies are described that facilitate avoidance of duplicative resource allocation and/or erroneous service charges via unambiguously indicating an entity responsible for quality of service (QoS) initiation. In one example, an indication is provided to a mobile device to indicate a preference for network-initiated QoS or a preference for device-initiated QoS. QoS for a data flow can be established in accordance with the indication. For instance, the mobile device initiates QoS when the indication specifies a preference for device-initiated QoS while a network establishes QoS when the indication specifies a preference for network-initiated QoS.
