Terminal Device Selective CGI Reporting for ANR Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing automatic neighbor relation (ANR) process in wireless communications is inefficient as it requires terminal devices to report cell global identifiers (CGIs) of target cells even when mobility between cells is not supported, leading to unnecessary energy consumption and signaling overheads.
Innovation Solution
A method where a terminal device selectively reports the CGI of a target cell only when it meets specific requirements, based on an indication from the network device, thereby reducing unnecessary reporting and optimizing energy consumption and signaling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device reports the CGI of the target cell to the network device in the ANR process, then the neighboring relation table can be maintained, but unnecessary reporting occurs when mobility is not supported, leading to increased energy consumption and signaling overheads
Solution Approach 1:
The terminal device performs selective reporting of CGI based on capability matching. Instead of reporting all target cell CGIs, it only reports those where the terminal has the capability to access the corresponding network type. This partial action approach eliminates unnecessary reporting while ensuring valid neighboring relation updates.
Solution Approach 2:
The reporting decision is made locally at the terminal device based on its own capability characteristics. The terminal evaluates whether it has the capability to access the network type of each target cell and makes an independent determination about reporting, rather than uniformly reporting all CGIs regardless of capability.

3Use of energy by moving object
If the terminal device selectively reports CGI based on capability, then energy consumption and signaling overheads are reduced, but the complexity of determining capability increases
Solution Approach 1:
The terminal device autonomously determines its own capability status for accessing different network types and uses this self-assessed capability information to decide whether to report CGI. This self-service mechanism eliminates the need for complex external capability verification procedures, reducing overall system complexity while enabling selective reporting.

AI summary
This application provides a communications method and apparatus. The method includes: receiving neighboring cell reporting indication information from a network device; and determining, based on a target cell obtained through measurement and the neighboring cell reporting indication information, whether to report a cell global identifier (CGI) of the target cell to the network device. According to the communications method provided in this application, during maintenance of a neighboring relation table, a terminal device can selectively report, based on an indication of the network device, only a CGI of a target cell that meets a requirement, to reduce unnecessary reporting, reduce energy consumption of the terminal device, and reduce signaling overheads.
