Solution Overview
Problem
In heterogeneous wireless communication networks with numerous low-power nodes, frequent handovers and cell reselections lead to network overload and poor user experience due to the inability to determine frequently accessed cells, causing service interruptions and inefficient resource utilization.
Innovation Solution
A method and device for determining a target cell by acquiring and analyzing cell statistic information, including specific information about served cells and mobile terminals, to identify preferred cells for handover and reselection, thereby optimizing cell selection and reducing unnecessary handovers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a large number of low-power nodes are deployed to enhance coverage and improve throughput, then network coverage and capacity are improved, but the number of cell borders increases causing frequent handovers and network overload
Solution Approach 1:
The patent implements a feedback mechanism where the network side device collects cell statistic information (including specific information about served cells and mobile terminals) and uses this feedback to intelligently determine target cells. This feedback loop enables the system to adapt to the increased number of cell borders by making informed handover decisions based on historical data, thereby managing the complexity introduced by numerous low-power nodes.
2Productivity
If low-power nodes are deployed in hotspots for traffic offloading, then network capacity is improved, but the inability to determine frequently accessed cells causes service interruptions and poor user experience
Solution Approach 1:
The patent applies preliminary action by collecting and analyzing cell statistic information in advance to determine preferred cells before handovers are needed. The network side device uses this pre-analyzed information to identify frequently accessed cells, ensuring that when handovers are required in hotspot areas, the system can quickly and reliably determine the appropriate target cell, thereby maintaining service continuity and improving user experience.
3Ease of operation
If traditional handover methods are used in heterogeneous networks, then basic connectivity is maintained, but frequent blind handovers consume excessive network resources and cause service interruptions
Solution Approach 1:
The patent implements self-service by enabling the network side device to autonomously analyze cell statistic information and determine preferred cells without requiring extensive manual configuration or intervention. The system serves itself by using its own collected data to make intelligent handover decisions, thereby maintaining basic handover capability while significantly reducing network resource consumption through targeted, informed handovers rather than frequent blind attempts.

AI summary
Embodiments of the present invention disclose a method and a device for determining a target cell. The method includes: acquiring information about a candidate cell for a mobile terminal; and determining the candidate cell as a target cell for the mobile terminal if the candidate cell is a preferred cell determined according to cell statistic information, where the cell statistic information includes: specific information about a cell having served the mobile terminal and specific information about the mobile terminal in the cell having served the mobile terminal. According to the solutions provided in the embodiments of the present invention, a proper target cell may be determined for a mobile terminal, thereby avoiding a large number of handovers and reselections and saving network resources.
