Bearer Allocation Method With Retain Flag For Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the existing bearer allocation methods result in high network signaling load and inefficient data processing when a large number of terminals frequently transmit small amounts of data, leading to network congestion and low system efficiency.
Innovation Solution
A bearer allocation method that marks bearers with a 'bearer retain flag' when certain conditions are met, allowing for the reservation of bearer context information even when the UE is in an IDLE state, enabling efficient data transmission without the need for frequent bearer recovery processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the UE enters IDLE state and bearer resources are released, then network resources are conserved, but bearer recovery process is required which increases signaling overhead
Solution Approach 1:
The patent applies preliminary action by pre-configuring bearers with retain characteristics before the UE enters IDLE state. When data needs to be transmitted, the network can directly use these pre-configured bearers without triggering the full bearer recovery process, thus reducing signaling overhead while maintaining resource efficiency.
Solution Approach 2:
The patent changes the state parameter of bearers by introducing a 'retain characteristic' flag. This parameter change allows certain bearers to be maintained in a reserved state even when UE enters IDLE, enabling direct data transmission without recovery procedures and reducing the signaling burden.
2Reliability
If bearer recovery process is initiated, then data transmission capability is restored, but network signaling load increases
Solution Approach 1:
The patent pre-establishes bearers with retain characteristics during initial network attachment or data transmission. These bearers are kept in a reserved state with their parameters stored, so when data transmission is needed again, the capability is immediately available without triggering extensive recovery signaling.
Solution Approach 2:
The patent extracts the essential bearer parameters and context information and stores them in a condensed form when the UE enters IDLE state. This extraction allows the network to quickly restore full bearer functionality without needing to exchange complete bearer setup signaling, thus reducing signaling load while maintaining transmission capability.
3Productivity
If frequent bearer recovery is performed, then data transmission is enabled, but system efficiency decreases
Solution Approach 1:
The patent pre-configures bearers with retain characteristics before they are needed for data transmission. This preliminary configuration ensures that when data needs to be transmitted frequently, the bearers are already in place and can be activated immediately without going through time-consuming recovery procedures, thus improving system efficiency.
Solution Approach 2:
The patent maintains bearers in a reserved state with their parameters stored, creating a continuous readiness for data transmission. This continuity eliminates the interruptions and delays associated with frequent bearer recovery processes, allowing data transmission to proceed efficiently without repeated setup overhead.

AI summary
A bearer allocation method, a User Equipment (UE), a base station, and a serving gateway are disclosed. The bearer allocation method includes: when a network entity creates a bearer for a UE, determining that the bearer has a bearer retain characteristic, and marking a bearer retain flag in bearer context information; and when the UE enters an IDLE state, an evolved base station and an SGW to which the UE belongs reserving the bearer context information marked with the bearer retain flag.
