Dynamic Overhead Message Transmission Rate Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Congested RF coverage areas in wireless communication systems can degrade service quality, and existing technologies lack effective methods to manage network load and prevent overloading, leading to delayed or prevented access for user equipment (UE) devices.
Innovation Solution
A network node dynamically adjusts the transmission rate of overhead messages based on detected wireless network conditions, allowing for quicker access to the system by UE devices and potentially avoiding the need for them to switch to adjacent coverage areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmission rate of overhead messages is increased, then network load is reduced and service quality is maintained, but UE devices are delayed or prevented from accessing the system
Solution Approach 1:
The patent applies dynamics by making the overhead message transmission rate adjustable rather than fixed. The network node dynamically changes the transmission rate based on real-time network conditions, allowing the system to adapt between high reliability modes (lower rates) and fast access modes (higher rates), thus resolving the contradiction between service quality maintenance and UE access speed.
Solution Approach 2:
The patent changes the transmission rate parameter of overhead messages based on network conditions. By varying this key parameter, the system can shift the balance between ensuring service quality and enabling quick UE access, directly addressing the technical contradiction through parameter optimization.
2Loss of time
If the transmission rate of overhead messages is decreased, then UE devices can access the system more quickly, but network load increases and service quality degrades
Solution Approach 1:
The system dynamically adjusts the transmission rate based on current network conditions, allowing it to decrease the rate when quick UE access is needed and increase it when service quality must be maintained. This dynamic adaptation resolves the contradiction by choosing the optimal rate at each moment rather than being fixed.
Solution Approach 2:
The network node monitors network conditions and uses this feedback to adjust the overhead message transmission rate. This feedback mechanism ensures that the system responds to real-time demands, decreasing the rate when access speed is prioritized and increasing it when service quality is the concern, thus resolving the technical contradiction.
3Device complexity
If overhead messages are transmitted at a fixed rate, then system complexity is reduced, but the system cannot adapt to changing network conditions and load
Solution Approach 1:
The patent introduces dynamics to the otherwise static fixed-rate system. The network node now actively adjusts the transmission rate based on network conditions, adding adaptability while managing complexity through condition-based decision logic rather than complex continuous optimization algorithms.
Solution Approach 2:
The system changes the transmission rate parameter based on detected network conditions, enabling adaptability to varying loads and conditions. This parameter adjustment mechanism provides versatility without requiring complete system redesign, thus balancing adaptability improvement with complexity management.

AI summary
Method and systems for selecting transmission rates for overhead communications within an RF network are described. The overhead communications can comprise network-access overhead communications, such as master information blocks in accordance with an LTE standard or access parameters messages in accordance with a CDMA standard. Selection of the transmission rate(s) can be based on conditions of a wireless network in which a network node and user equipment (UE) devices operate. A network node can determine the wireless network condition. A UE device can transmit measurement data to the network node for determining the wireless network condition. The network node can transmit, at a first rate, a first sequence of the overhead communications, such as one more overhead messages, detect the wireless network condition, select a second rate based on the detected network condition, and then transmit, at the second rate, a second sequence of the overhead communications.
