Network Equipment Selection via Pool Priority Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the UMTS system utilizing SAE, the existing methods for selecting network equipment often lead to unnecessary CN node relocation and inefficient network operation, particularly when a UE moves between overlapping pools or areas with different node capabilities, resulting in increased network costs and reduced efficiency.
Innovation Solution
A method and system that prioritize the selection of a primary pool or pool with the highest priority based on UE location and load balance principles, ensuring that network equipment with suitable capabilities is chosen, thereby minimizing node relocation and enhancing network efficiency.

Engineering Contradiction Analysis
1Productivity
If existing methods for selecting network equipment are used, then network equipment can be selected, but unnecessary CN node relocation occurs and network operation efficiency decreases
Solution Approach 1:
The patent applies preliminary action by pre-configuring pool priority information in the E-UTRAN node before UE attachment. When a UE needs to select network equipment, the E-UTRAN node directly uses the pre-stored pool priority information to determine the target pool, avoiding the need to select from multiple pools without clear guidance. This preliminary configuration prevents unnecessary CN node relocation and improves network operation efficiency.
2Loss of time
If pool priority information is configured in E-UTRAN node, then CN node relocation is reduced, but system complexity increases
Solution Approach 1:
The patent applies universality by making the pool priority configuration applicable to multiple E-UTRAN nodes across the network. The same pool priority information can be configured and stored in different E-UTRAN nodes, allowing them to all benefit from reduced CN node relocation. This multi-functional approach distributes the solution across the network infrastructure rather than requiring complex individual configurations at each node.
3Reliability
If UEs can access network equipment with necessary service capabilities, then service quality improves, but equipment overhead increases
Solution Approach 1:
The patent applies local quality by enabling UEs to access network equipment with specific service capabilities through the pool priority mechanism. Different pools can be associated with different service capabilities, and by directing UEs to specific pools based on priority information, the system ensures that UEs receive appropriate service capabilities without requiring all network equipment to have all capabilities. This reduces overall equipment overhead while maintaining service quality.

AI summary
A method and a system for selecting network equipment are provided. The method includes: selecting a primary pool or a pool with the highest priority from preset information when UE needs to select network equipment; and selecting the network equipment for the UE from the selected primary pool or pool with the highest priority. Thus, the relocation times of an MME and a serving SAE gateway are effectively reduced and an operation efficiency of a network is enhanced. Meanwhile, the UE having or subscribing a new service function selects to be attached to the network equipment with the new service function within a pool, such that the diversity demands for service development are satisfied, and the equipment overhead is saved.
