Application Network Dynamic Service Bearer Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication networks, existing methods for setting up service bearers fail to adapt to changes in access network resources, leading to deteriorated Quality of Service (QoS) and potential service interruptions when resources are congested.
Innovation Solution
The method involves the application network receiving resource information from the access network and adjusting service requests or parameters to match the current resource status, ensuring that service parameters or requests align with changed access network resources, thereby improving QoS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a service bearer is set up using prior art methods, then the bearer is established for data exchange, but the bearer does not adapt to changes in access network resources, causing QoS deterioration
Solution Approach 1:
The patent implements dynamic service bearer configuration by enabling the service bearer to be adjusted in real-time based on access network resource changes. The network controller receives resource status information from the access network and dynamically modifies bearer parameters (such as bandwidth allocation, QoS parameters) to match current network conditions, transforming the static bearer setup into a dynamic adaptive system that maintains optimal performance despite resource fluctuations
Solution Approach 2:
The patent establishes a feedback mechanism where the access network continuously reports resource status information to the network controller, which then adjusts service bearer parameters accordingly. This closed-loop control system monitors access network resource changes and feeds this information back to modify bearer configurations, ensuring the bearer always matches current network capabilities and preventing QoS deterioration
2Ease of operation
If the service request is formed based on initial resource status, then the service negotiation is completed, but the service request does not match changed access network resources, leading to service interruption
Solution Approach 1:
The patent applies preliminary action by pre-configuring the feedback mechanism and dynamic adjustment capabilities before service interruptions occur. The system is prepared in advance to receive resource status changes and automatically adjust service requests, so when network conditions change, the service can be maintained without interruption rather than requiring reactive re-negotiation
Solution Approach 2:
The service request parameters are made dynamic rather than fixed. The network controller continuously monitors access network resource status and automatically updates service request parameters (such as bandwidth requirements, QoS levels) to match current network conditions, transforming the static service negotiation into an adaptive process that maintains service continuity despite resource changes

AI summary
When a resource of an access network is changed, receiving, by an application network, resource information sent by the access network, where the resource information is information that indicates a current resource status of the access network; and adjusting, by the application network, a service request related to a current service according to the resource information and sending the adjusted service request to the access network; or negotiating, by the application network, a current service parameter with a User Equipment UE according to the resource information, so that the UE modifies the parameter related to the current service according to a result of the negotiation. In the embodiments of the present invention the service parameter or the service request related to the current service matches the changed access network resource, thereby improving the QoS.
