Mobile Device Automatic Neighbor Relation Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic neighbor relation functions in wireless telecommunications networks often result in redundant information being transmitted, leading to wasted network and mobile device resources, as well as increased power consumption, due to the repeated detection and reporting of previously identified neighbor cells.
Innovation Solution
A mobile device equipped with measurement logic to determine if neighbor relations have been previously reported, generating new relations only when necessary, and utilizing a neighbor relation log with indicators to prevent redundant reporting, thereby reducing unnecessary measurements and resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile devices continuously detect and report neighboring cells in automatic neighbour relation mode, then complete neighbor relation information is provided to the network, but redundant information is transmitted causing wasted network and device resources
Solution Approach 1:
The mobile device maintains a local log of previously reported neighbor relations before performing detection. This preliminary record allows the device to compare newly detected cells against the log and avoid reporting duplicates, thereby preventing redundant transmissions and conserving energy while maintaining information completeness.
Solution Approach 2:
The device uses feedback from its own previous reporting activity (stored in the neighbor relation log) to control future detection and reporting behavior. By checking the log before reporting, the device receives feedback on what has already been communicated, avoiding redundant energy-consuming transmissions.
2Reliability
If mobile devices continuously detect and report neighboring cells, then accurate neighbor relations are established in the network, but network resources are wasted processing redundant information
Solution Approach 1:
The network node maintains a record of previously received neighbor relations before processing new reports. This preliminary documentation enables the network to quickly identify and discard duplicate information, ensuring accurate neighbor relations are established while preventing waste of network processing resources on redundant data.
Solution Approach 2:
The network uses feedback from previously processed reports (stored in its record) to control the handling of incoming reports. By comparing new reports against the stored record, the network receives feedback on redundancy, allowing it to filter out duplicates and maintain resource efficiency while ensuring accuracy.
3Loss of information
If mobile devices perform measurements of all detected neighboring cells, then complete measurement data is available for network optimization, but device processing load and power consumption increase
Solution Approach 1:
The mobile device checks its neighbor relation log before performing measurements on detected cells. This preliminary check identifies which cells have already been reported, allowing the device to skip redundant measurements entirely, thereby reducing energy consumption while maintaining measurement data completeness for all unique neighbor relations.
Solution Approach 2:
The device uses feedback from its measurement history (stored in the log) to control future measurement activities. By comparing detected cells against the log, the device receives feedback on which measurements have already been performed and reported, avoiding duplicate energy-consuming measurements while ensuring complete data collection for all unique neighbors.

AI summary
A mobile device operable to perform automatic neighbor relation functions in a wireless telecommunications network, a radio network controller, methods and a computer program product are disclosed. The mobile device is operable to perform automatic neighbor relation functions in a wireless telecommunications network in which neighbor relations derived by the mobile device are provided to a network node of the wireless telecommunications network and comprises: measurement logic operable, in an automatic neighbor relation mode, to measure characteristics of a neighboring cell; and determination logic operable to determine, from the characteristics and from an indication of previously provided neighbor relations, whether a neighbor relation based on the characteristics has been provided previously to the network node and, if not, to generate a new neighbor relation to be provided to the network node. Hence, only neighbor relations which are not indicated as having been provided previously need be generated.
