Cell Activation Priority Sequencing for Base Station Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE wireless communications systems, insufficient base station resources can lead to important cells being unable to provide services, affecting system stability, especially when a large number of cells need to be activated and resources are limited or faulty.
Innovation Solution
A method where a base station determines and prioritizes multiple target cells for activation, preferentially allocating resources to cells with higher priority, and deactivates abnormal cells to activate higher-priority cells not initially activated due to resource constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cells are activated simultaneously without priority sequencing, then all cells have equal opportunity to acquire resources, but important cells may fail to acquire resources when base station resources are insufficient
Solution Approach 1:
The patent applies preliminary action by determining priority sequences of target cells before resource allocation. The base station identifies multiple target cells that need activation, assigns priorities based on service importance, and pre-establishes an activation sequence. This ensures that when resources are limited, high-priority cells are guaranteed resource allocation first, preventing service failures for critical cells while maintaining a structured approach to resource management.
2Productivity
If base station resources are allocated to activate all target cells, then more cells can provide services, but resource insufficiency or faults may cause some cells to fail activation
Solution Approach 1:
The patent applies segmentation by dividing the set of target cells into priority groups and activating them in sequence rather than simultaneously. The base station segments cells based on service importance, activates high-priority cells first with guaranteed resource allocation, then proceeds to lower-priority cells if resources remain. This segmented approach ensures that limited resources are distributed to maximize both the number of active cells and the reliability of critical services.
3Reliability
If abnormal cells are not deactivated to make resources available, then currently active cells maintain service, but higher-priority target cells cannot be activated due to resource constraints
Solution Approach 1:
The patent applies dynamics by implementing a flexible resource allocation mechanism that can dynamically adjust between active cells and target cells based on priority and service status. When an abnormal cell is detected among target cells, the system dynamically evaluates whether to deactivate it to reallocate resources to higher-priority cells. This dynamic approach allows the base station to adapt resource distribution in real-time, balancing service stability with the ability to activate critical cells that require resources.

AI summary
This application provides a cell activation method and apparatus. After multiple cells to be activated are determined, the multiple cells are activated in sequence according to a priority sequence of the multiple cells, so that in a case in which base station resources are insufficient, an important cell ranking higher in the priority sequence is preferentially activated to preferentially occupy the base station resource and provide a service to the outside, and further, stability of a wireless communications system is improved.
