Bearer Signalling Management via Unified Resource Request
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing bearer management procedures in wireless communication networks lead to delayed service access and underutilization of backhaul bandwidth due to the excessive exchange of messages between user equipment (UE) and relay nodes (RN) for creating or modifying bearers, resulting in inefficient radio and backhaul resource utilization.
Innovation Solution
A method is introduced to optimize bearer management by transporting a single 'Union of Resource Request' (UR Request) signalling message from Evolved Packet Edge (EPE) entities to managing entities via the Donor-eNB (DeNB) and receiving a single 'Union of Admission Response' (UA Response) message, which simplifies the bearer setup process and reduces message exchange, thereby enhancing resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate bearer management procedures are used for UE and RN, then individual bearers can be managed independently, but message exchange overhead increases and service access is delayed
Solution Approach 1:
The patent combines separate bearer management procedures for UE and RN into a single unified procedure. The RN includes UE bearer management requests and RN bearer management requests in a single message exchange with the DeNB, eliminating the need for separate message exchanges and reducing overall complexity while maintaining independent management capability.
Solution Approach 2:
The unified bearer management procedure serves multiple functions simultaneously - it handles both UE bearer creation/modification and RN bearer creation/modification through a single procedure, making the system more efficient while maintaining the ability to manage different bearer types independently.
2Reliability
If multiple separate messages are exchanged for bearer creation/modification, then detailed control is maintained, but backhaul bandwidth is wasted and resources are underutilized
Solution Approach 1:
The patent merges multiple separate message exchanges into a single unified message exchange. The RN aggregates UE bearer management messages and RN bearer management messages into one combined procedure, reducing the number of messages traversing the backhaul and improving bandwidth utilization while maintaining detailed control through structured message formatting.
3Adaptability or versatility
If separate bearer management procedures are used, then individual bearer requirements can be addressed, but service access time is increased
Solution Approach 1:
The patent enables preliminary aggregation of bearer management requests at the RN before transmitting to the DeNB. The RN can prepare and combine multiple bearer management messages in advance, allowing for more efficient processing and reducing the time required for service access while still addressing individual bearer requirements through the structured unified message format.

AI summary
A method for bearer signalling management in a communication network comprising of transporting bearer resource request message of both the UE and RN via DeNB to managing entity of RN within EPC, as a signalling message over uplink channel referred to as ‘Union of Resource Request (UR Request)’ message. The bearer resource response message from one of the managing entity of RN or managing entities of UE and RN within EPC are transported as a signalling message to Evolved Packet Edge (EPE) via DeNB over the downlink channel referred to as ‘Union of Admission Response (UA Response)’. This manages bearer setup signalling as a single loop, by transportation of ‘UR Request’ signalling message and receiving one ‘UA Response’ signalling message over uplink and downlink channels respectively. EPE is a conglomeration of network nodes comprising of UEs, RNs and all other network nodes that communicate over EPC via DeNB.
