Radio Resource Allocation Control in Mobile Communication Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In E-UMTS systems, continuous allocation and use of radio resources in connected mode are inefficient due to IP packet-based services that do not always communicate packets, leading to waste, as terminals lack information about uplink data and base stations cannot estimate radio resource needs without terminal notifications.
Innovation Solution
A method where the network transmits access control information to terminals, allowing them to selectively request radio resource allocation based on received information, including radio bearer, call type, service type, priority, and time information, to minimize unnecessary requests and optimize resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous radio resource allocation is used in connected mode, then terminal connectivity is maintained, but radio resource waste increases due to IP packet-based services that do not always communicate
Solution Approach 1:
The patent implements dynamic radio resource allocation by transitioning from continuous static allocation to on-demand dynamic allocation. The network dynamically adjusts allocation status based on actual data transmission needs, allowing terminals to request resources only when needed rather than maintaining continuous allocation, thus resolving the contradiction between connectivity reliability and resource waste.
Solution Approach 2:
The patent introduces feedback mechanisms where terminals notify the network of their data transmission needs. The network uses this feedback information to determine whether to allocate radio resources, creating a closed-loop system that prevents both resource waste and connectivity failures by responding to actual terminal requirements.
2Reliability
If base station continuously allocates radio resources, then terminal data transmission is ensured, but resource utilization efficiency decreases due to lack of terminal data information
Solution Approach 1:
The patent implements feedback mechanisms where terminals notify the network of their data transmission needs. The network uses this feedback information to determine whether to allocate radio resources, creating a closed-loop system that prevents both resource waste and connectivity failures by responding to actual terminal requirements.
Solution Approach 2:
The patent applies preliminary action by having terminals prepare and notify the network of their data transmission intentions in advance. This allows the network to proactively allocate resources before actual transmission occurs, ensuring both reliability and efficiency without requiring continuous monitoring or reactive allocation.
3Productivity
If terminal requests radio resource allocation continuously, then data transmission opportunity increases, but unnecessary requests waste network processing resources
Solution Approach 1:
The patent applies preliminary action by having terminals prepare and notify the network of their data transmission intentions in advance. This allows the network to proactively allocate resources before actual transmission occurs, ensuring both reliability and efficiency without requiring continuous monitoring or reactive allocation.

AI summary
In a wireless mobile communications system, a method for controlling a radio resource allocation is provided. A network transmits access control information to a terminal such that a request for the radio resource allocation which will be transmitted from the terminal can be controlled. The terminal selectively transmits the request for the radio resource allocation based on the received information, thus a transmission of an unnecessary request for the radio resource can be minimized, thereby preventing a waste of the radio resource.
