Bearer Maintenance for Signaling Reduction in Mobile Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Frequent initiation of connection setup and radio access bearer setup processes by smartphones leads to excessive signaling interactions in communication systems, impacting network performance.
Innovation Solution
Implementing a method where network entities, such as SGSN and RNC, maintain bearers corresponding to user equipment for a specific duration, reducing the need for repeated setup processes and optimizing signaling interactions by using bearer instruction messages to manage RABs and Iu connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If smartphones initiate connection setup and radio access bearer setup processes for frequent packet services, then services can be re-initiated, but excessive signaling interactions occur between air interfaces and Iu interfaces
Solution Approach 1:
The network side performs preliminary actions by maintaining bearers in a dormant state and pre-configuring connection parameters. When services need to be re-initiated, the smartphone can quickly restore connections using the pre-maintained bearer resources, avoiding repeated setup processes and reducing signaling interactions.
2Loss of energy
If smartphones return to idle mode after sending heartbeat packets, then power consumption is reduced, but connection setup processes must be re-initiated
Solution Approach 1:
The patent implements dynamic state management where bearers transition between active, dormant, and released states based on service patterns. The network monitors service frequency and dynamically adjusts bearer maintenance strategies, keeping bearers dormant for frequent services to reduce setup time while releasing them for infrequent services to save power.
3Quantity of substance
If network releases bearers and connections after smartphones enter idle mode, then network resources are freed, but repeated setup processes increase signaling load
Solution Approach 1:
The patent applies differentiated bearer management strategies based on service characteristics. For frequent packet services like heartbeat packets, bearers are maintained in dormant state to avoid repeated setup signaling. For infrequent services, bearers are released to free network resources. This local quality approach optimizes both resource utilization and signaling efficiency.
