Service Request Completion via RRC Release in Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of user equipment (UEs) and data volume in wireless communication systems pose challenges for base stations (BS) to efficiently transmit and receive uplink/downlink data and control information using limited radio resources, particularly with the rise of smart devices and machine-to-machine communication.
Innovation Solution
A method where user equipment (UE) transmits an EPS mobility management (EMM) message including uplink data, and upon receiving an RRC connection release indication or downlink data, considers the service request procedure as successfully completed, allowing for efficient data transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of user equipments (UEs) and data volume increase to satisfy rapidly increasing data throughput demands, then data transmission capacity improves, but the complexity of resource management at base stations worsens
Solution Approach 1:
The patent segments the service request procedure into distinct phases: UE initiates service request, network processes it, and network responds with connection release indication or downlink data. This segmentation allows independent optimization of each phase, reducing overall system complexity while maintaining high throughput capability.
Solution Approach 2:
The network node performs preliminary actions by sending connection release indication or downlink data to explicitly indicate successful service request completion. This preliminary indication mechanism allows the UE to proactively determine procedure completion without waiting for additional signaling, reducing management complexity.
2Reliability
If traditional service request procedures are used where UE waits for explicit confirmation, then reliability of procedure completion detection improves, but communication efficiency and throughput worsen
Solution Approach 1:
Instead of the UE waiting for explicit confirmation of service request completion, the patent inverts the approach: the network sends connection release indication or downlink data that simultaneously serves as completion confirmation. This inversion eliminates the need for separate confirmation signaling, improving efficiency while maintaining reliability through the dual-purpose nature of these messages.
Solution Approach 2:
The connection release indication and downlink data serve multiple functions: they deliver network control information to the UE and simultaneously indicate successful service request completion. This multi-functionality reduces signaling overhead and improves communication efficiency without compromising reliability.
3Adaptability or versatility
If existing service request mechanisms are used for small and infrequently occurring data, then protocol compatibility is maintained, but transmission efficiency and resource utilization worsen
Solution Approach 1:
The patent changes the parameter of service request completion indication from requiring explicit confirmation messages to using existing connection release or downlink data messages as completion indicators. This parameter change maintains protocol compatibility while dramatically improving transmission efficiency for small and infrequent data transmissions.

AI summary
A user equipment can send an EPS mobility management (EMM) message including uplink data to a network node. The user equipment can determine that an EMM process complying with the EMM message has successfully been completed or can treat an EMM process complying with the EMM message as having been successfully completed if the user equipment receives an RRC disconnection, downlink data or service acceptance message for the EMM message.
